The Central Executive is responsible for supervising and coordinating the activities of the slave systems (the phonological loop and the visuo-spatial sketchpad). It monitors incoming information and allocates attentional resources to different tasks. In this scenario, Amira must balance visual/spatial task demands (steering the car and watching the road) and auditory/verbal task demands (listening to GPS instructions), a coordination process managed by the central executive.

1 mark for the correct identification of option A.
0 marks for any other option selected.

In Milgram's remote-authority variation (where instructions were given over the telephone), the physical distance between the authority figure and the participant increased (proximity variable). This resulted in a significant drop in obedience from the original baseline of 65% to approximately 20.5%. Some participants even pretended to give shocks or gave weaker shocks than required.

1 mark for the correct identification of option A.
0 marks for any other option selected.

In a cognitive interview, the interviewer instructs the witness to 'report everything', including details that the witness might deem unimportant or irrelevant to the case. This technique helps in two main ways:
1. **Retrieval Cues**: Seemingly trivial details can act as effective triggers (cues) that help the brain access more significant, associated memories of the event that might otherwise remain inaccessible (cue-dependent recall).
2. **Reducing Reconstruction**: Asking for all details prevents the witness from using their schema or post-event information to fill in the gaps, which helps maintain the objective accuracy of the actual events witnessed.

Award marks as follows:
- **1 mark** for showing understanding of 'report everything' (e.g., requesting all details, even those that seem trivial or minor).
- **1 mark** for explaining the cognitive mechanism (e.g., acting as retrieval cues, triggering associated memories, or cue-dependent retrieval).
- **1 mark** for linking this to improved accuracy (e.g., preventing filtering or reducing reliance on schemas/reconstructive memory).

The phonological loop is a slave system in Baddeley and Hitch's Working Memory Model (WMM) dedicated to processing and temporarily storing auditory and verbal information.

It is subdivided into:
1. **The Phonological Store ('inner ear')**: This component holds acoustic information (words you hear) for a very brief duration (typically 1–2 seconds) before it decays.
2. **The Articulatory Control Process ('inner voice')**: This component allows for maintenance rehearsal (repeating words sub-vocally) to prevent decay and to translate written words into an auditory code so they can enter the phonological store.

Award marks as follows:
- **1 mark** for outlining the general function of the phonological loop (processing/temporary storage of auditory, verbal, or acoustic information).
- **1 mark** for identifying and defining the phonological store ('inner ear' / holds spoken words briefly).
- **1 mark** for identifying and defining the articulatory control process ('inner voice' / handles sub-vocal rehearsal).

Milgram proposed the agency theory to explain obedience.

Key aspects of the agentic state include:
- **Definition**: It is a psychological state in which an individual views themselves as an instrument (agent) for carrying out another person's wishes. They no longer see themselves as responsible for their own actions.
- **The Agentic Shift**: People typically start in an autonomous state, where they feel voluntary control and personal responsibility. When ordered by a perceived legitimate authority figure, they undergo an 'agentic shift' into the agentic state.
- **Binding Factors**: Aspects of the situation (such as fear of appearing rude or the gradual commitment of the tasks) help keep the individual in this state, despite experiencing high levels of moral strain.

Award marks as follows:
- **1 mark** for defining the agentic state (acting as an agent of an authority figure, shifting responsibility to them, or feeling no personal accountability).
- **1 mark** for contrasting it with the autonomous state (where an individual acts independently and takes personal responsibility for their choices).
- **1 mark** for explaining why/how it occurs (the agentic shift triggered by a perceived legitimate authority figure, or the influence of binding factors).

For minority influence to be effective, consistency is crucial. There are two types of consistency:
1. **Synchronic Consistency**: All members of the minority group agree and say the same thing.
2. **Diachronic Consistency**: The minority group has been saying the same thing for a long period of time.

Consistency is powerful because it draws attention to the minority's cause. It conveys confidence, certainty, and dedication to their position. This persistent message forces the majority to pause and deeply process/re-evaluate their own assumptions (cognitive conflict), which can eventually lead to internalisation or conversion.

Award marks as follows:
- **1 mark** for outlining what consistency means in this context (e.g., synchronic/agreement within the group or diachronic/maintaining the same view over time).
- **1 mark** for explaining the impact on the majority's processing (e.g., forces cognitive conflict, reassessment of their own views, or draws serious attention to the issue).
- **1 mark** for linking this to successful social influence (e.g., demonstrates confidence, resolve, and credibility, leading to conversion/internalisation).

In psychopathology, behavioral characteristics refer to the physical actions or behaviors displayed by an individual with a phobia. Three key behavioral characteristics are:
1. **Panic**: When confronted with the phobic stimulus, the person may exhibit high levels of distress, which can present as crying, screaming, running away, or 'freezing'.
2. **Avoidance**: The person will make active efforts to prevent coming into contact with the phobic stimulus. This can severely restrict their lifestyle, daily routine, or social life (e.g., avoiding parks due to a fear of dogs).
3. **Endurance**: This occurs when the sufferer is forced to remain in the presence of the phobic stimulus and cannot avoid it. They tolerate the situation but experience high, continuous levels of anxiety throughout the exposure.

Award **1 mark** for each clearly outlined behavioral characteristic of a phobia, up to a maximum of **3 marks**:
- Panic (must be described as a behavioral reaction, e.g., crying, screaming, fleeing, freezing).
- Avoidance (must mention the proactive avoidance of the phobic stimulus and/or its impact on daily life).
- Endurance (must mention staying in the presence of the stimulus while suffering extreme anxiety).

*Note: Do not accept emotional characteristics (e.g., feeling fear) or cognitive characteristics (e.g., irrational beliefs) for behavioral marks.*

The biological explanation of OCD suggests that genetic vulnerability is inherited through specific 'candidate genes'.

Key points about their involvement:
- **Polygenic Nature**: OCD is not caused by a single gene but is polygenic, meaning multiple candidate genes (up to 230, according to some studies) act together to increase vulnerability.
- **Neurotransmitter Regulation**: These genes are typically involved in regulating the transmission of key neurotransmitters in the brain.
- **Specific Examples**:
- The **SERT gene** is involved in the transport of serotonin. A mutation/variation in this gene can lead to lower levels of active serotonin in the synapse.
- The **COMT gene** regulates the production of dopamine. Variations can lead to higher levels of dopamine. Both imbalances are associated with the characteristic repetitive behaviors and intrusive thoughts in OCD.

Award marks as follows:
- **1 mark** for explaining that candidate genes create a genetic vulnerability/predisposition to OCD and that OCD is polygenic (involves multiple genes).
- **1 mark** for explaining that these genes specifically affect the regulation/transmission of neurotransmitter systems in the brain.
- **1 mark** for providing a specific example of a candidate gene (e.g., COMT gene leading to high dopamine levels, or SERT gene leading to low serotonin levels).

In Cognitive Behavioral Therapy (CBT) for depression (e.g., based on Beck's cognitive therapy or Ellis's REBT), the therapist aims to identify and systematically challenge the client's irrational and negative thoughts.

This process involves:
1. **Identification**: The therapist helps the client notice automatic negative thoughts (such as catastrophising or negative views of the self, world, and future in Beck's cognitive triad).
2. **Gathering Evidence ('Patient as Scientist')**: The therapist sets behavioral homework tasks (e.g., keeping a diary of times people were nice to them or recording small achievements). This turns the client into an investigator searching for objective facts.
3. **Disputing and Reframing**: In subsequent sessions, when the client makes an irrational claim (e.g., "I am completely useless and never succeed at anything"), the therapist uses the collected evidence to challenge the validity of this belief. This cognitive restructuring helps the client replace negative thoughts with more realistic, positive beliefs.

Award marks as follows:
- **1 mark** for explaining how the therapist identifies negative/irrational thoughts (e.g., using Beck's cognitive triad or automatic thoughts).
- **1 mark** for describing a specific challenging method (e.g., 'patient as scientist', empirical/logical disputing, reality testing, or setting behavioral homework to gather evidence).
- **1 mark** for explaining how the therapist uses this evidence/process to actively disprove the irrational thought and reframe the client's perspective.

To help Maya recall details about the getaway vehicle and the driver's appearance, DI Carter can use the following two techniques:

1. **Mental Reinstatement of Context**:
- **How it works**: DI Carter should ask Maya to mentally put herself back at the scene of the bank robbery. He can ask her to imagine the weather, the sounds, the time of day, and how she was feeling at that moment.
- **Application**: This serves as a retrieval cue (based on the encoding specificity principle), which can help Maya recall details about the getaway car or the driver that she encoded at the time but cannot immediately access.

2. **Report Everything**:
- **How it works**: DI Carter should instruct Maya to report every single detail about the vehicle and driver, even if it seems completely irrelevant, trivial, or if she feels uncertain about it.
- **Application**: Seemingly minor details (e.g., a scratch on the car door or a specific hat the driver wore) can act as a trigger or cue to unlock more significant memories, such as the registration plate or facial features.

**Level 3 (5–6 marks):**
- Explanations of two cognitive interview techniques are clear and accurate.
- Application to Maya and the bank robbery is highly appropriate and effectively integrated.
- The answer is structured logically with appropriate psychological terminology.

**Level 2 (3–4 marks):**
- Knowledge of one or both techniques is present but may lack detail or clarity.
- There is some attempt at application to the scenario, but it may be limited or inconsistent.

**Level 1 (1–2 marks):**
- Knowledge of cognitive interview techniques is basic or superficial.
- Little to no application to the scenario.

**Possible points to cover (select two):**
- **Context reinstatement**: Mentally returning to the scene of the robbery to access environmental and state-dependent retrieval cues.
- **Report everything**: Sharing all details without editing, which may trigger connected memories of the car/driver.
- **Change perspective**: Imagining the robbery from the perspective of another witness or the bank teller to bypass schema-driven memory gaps.
- **Reverse order**: Recalling the robbery events starting from the getaway and working backward to prevent expectations from distorting the recall.

Sarah's compliance can be explained using several obedience factors:

1. **The Agentic State**:
- **Explanation**: In an autonomous state, individuals feel personally responsible for their actions. Under pressure from an authority figure, they can undergo an 'agentic shift' to an agentic state, where they believe they are acting as an agent carrying out another's wishes.
- **Application**: Sarah demonstrates this when she shifts responsibility away from herself, saying, 'it's his responsibility if anything goes wrong,' allowing her to cope with her anxiety (moral strain).

2. **Legitimacy of Authority and Uniform**:
- **Explanation**: People are socialized to obey individuals who possess legitimate authority within a social hierarchy. Uniforms act as strong visual cues indicating status and authority.
- **Application**: The doctor is a 'senior consultant,' occupying a high position in the hospital hierarchy. His authority is further signaled by his uniform ('white lab coat' and 'stethoscope'), which legitimizes his power to give instructions.

3. **Proximity**:
- **Explanation**: Milgram's variations demonstrated that physical proximity to an authority figure increases obedience rates.
- **Application**: Sarah mentions that the consultant was 'standing right there watching me.' This close physical proximity increased the pressure on Sarah to obey immediately.

**Level 3 (5–6 marks):**
- Clear, detailed explanation of at least two relevant explanations of obedience (e.g., agentic state, legitimacy of authority/uniform, proximity).
- Excellent application to the scenario, directly linking the theoretical concepts to Sarah's behavior and quotes.
- Well-structured with accurate psychological terminology.

**Level 2 (3–4 marks):**
- Explanations of obedience factors are mostly clear but may lack depth.
- Some application to Sarah, but connections may be loose or incomplete.

**Level 1 (1–2 marks):**
- Basic or superficial knowledge of obedience explanations.
- Minimal or no application to the scenario.

**Acceptable explanations include:**
- **Agentic State**: Transferring responsibility to the consultant.
- **Legitimate Authority**: Hospital hierarchy and the consultant's status.
- **Uniform**: White lab coat and stethoscope as markers of authority.
- **Proximity**: The physical closeness of the consultant supervising her.

A therapist would use systematic desensitisation (SD) to help Leo overcome his phobia of dogs through three distinct stages:

1. **Anxiety Hierarchy**:
- The therapist and Leo would work together to construct a hierarchy of situations involving dogs, ordered from least to most fear-inducing. For example, the lowest level might be looking at a cartoon of a dog, a mid-level might be watching a dog on a leash through a window, and the highest level might be petting a real dog in a park.

2. **Relaxation Training**:
- The therapist teaches Leo relaxation techniques, such as deep muscle relaxation, breathing exercises, or mental imagery. The psychological principle is 'reciprocal inhibition'—Leo cannot feel anxious and completely relaxed at the same time.

3. **Graduated Exposure**:
- Leo is exposed to the phobic stimulus gradually, starting at the lowest level of his hierarchy. He must practice his relaxation techniques until he is completely calm and anxiety-free at that level. Only then do they move up to the next stage. This continues until Leo can successfully cope with the highest level of his hierarchy (e.g., encountering a dog) without feeling terror.

**Level 3 (5–6 marks):**
- Accurate, comprehensive description of all three stages of systematic desensitisation (anxiety hierarchy, relaxation training, and graduated exposure).
- Consistent, effective application to Leo and his phobia of dogs throughout the response.
- Clear and logical structure.

**Level 2 (3–4 marks):**
- Description of the stages is mostly accurate, though one stage may be lacking detail or omitted.
- There is some application to Leo and dogs, but it may be superficial or inconsistent.

**Level 1 (1–2 marks):**
- Basic or superficial knowledge of systematic desensitisation is shown.
- Minimal or no application to the scenario.

**Key terms/steps to look for:**
- **Anxiety hierarchy**: Tailored list of fears from low to high involving dogs.
- **Relaxation training**: Deep breathing, muscle relaxation.
- **Graduated exposure**: Step-by-step progress through the hierarchy.
- **Reciprocal inhibition**: The concept that relaxation inhibits anxiety.

The working memory model (WMM), proposed by Baddeley and Hitch (1974), suggests that short-term memory is an active processor consisting of multiple components rather than a single unitary store. The model comprises four main components: the central executive, the phonological loop, the visuo-spatial sketchpad, and the episodic buffer. The central executive acts as the 'boss' of the system, monitoring incoming data, making decisions, and allocating slave systems to tasks. It has a very limited processing capacity. The phonological loop deals with auditory information and is subdivided into the phonological store ('inner ear') and the articulatory control process ('inner voice'). The visuo-spatial sketchpad processes visual and spatial information, consisting of the visual cache (storing visual data) and the inner scribe (recording spatial arrangements). The episodic buffer, added in 2000, integrates information from the other components and long-term memory, maintaining a sense of time sequencing. An outstanding strength of the WMM is the support from dual-task performance studies. Baddeley et al. demonstrated that participants had more difficulty performing two visual tasks simultaneously than performing a visual and a verbal task together. This supports the existence of separate slave systems (visuo-spatial sketchpad and phonological loop) because they do not compete for the same limited resources. Clinical evidence from brain-damaged patients, such as KF, further supports the model. KF suffered short-term memory impairment mainly for verbal information, while his visual processing remained intact. This indicates that his phonological loop was damaged but his visuo-spatial sketchpad was functioning normally, confirming the independence of these components. However, a major limitation of the WMM is the lack of clarity regarding the central executive. Many psychologists argue that the concept of the central executive is too vague and its exact functions are not fully understood, with some suggesting it may consist of separate sub-components. This limits the explanatory power of the model as a whole.

Minority influence occurs when an individual or small group influences the beliefs and behaviours of a larger majority. To achieve social change, the minority must display specific behavioural styles: consistency, commitment, and flexibility. Consistency involves maintaining the same message over time (diachronic consistency) and agreement among minority members (synchronic consistency). Commitment shows dedication to the cause, often through personal risks or sacrifices (the augmentation principle). Flexibility requires the minority to negotiate and accept reasonable compromises rather than appearing dogmatic. Over time, these behaviours lead to the snowball effect, where more people convert to the minority view until it becomes the majority norm, culminating in social cryptomnesia, where the origin of the change is forgotten. In the school scenario, the 'green committee' represents the minority. Their 'consistent' campaign means they repeatedly delivered the same message about recycling throughout the term. 'Commitment' is shown by their sustained dedication to organising the campaign, potentially dedicating their own free time. Their 'flexibility' could involve adapting their proposals to fit the school's existing schedule, making it easier for students to participate. As more students began to recycle, the 'snowball effect' occurred, eventually converting the 'majority of students and staff'. Research support comes from Moscovici et al.'s blue-green slide study, which demonstrated that a consistent minority was significantly more effective at influencing the majority than an inconsistent one. Nemeth (1986) also supported flexibility, showing that a flexible minority in a mock jury was more persuasive than a rigid one. However, minority influence is often slow to occur, and the majority may dismiss the minority as 'deviant' or 'troublemakers', limiting the real-world application of these laboratory findings. Additionally, most research uses artificial tasks (e.g., judging slide colours) that lack ecological validity compared to real-life social movements.

AO1 (6 marks): Award up to 6 marks for explanation of minority influence processes (consistency, commitment, flexibility, snowball effect, social cryptomnesia) leading to social change. AO2 (4 marks): Award up to 4 marks for application to the school recycling scenario (e.g., identifying green committee as minority, showing how consistency, commitment, flexibility, and snowball effect apply to their campaign). AO3 (6 marks): Award up to 6 marks for evaluation of minority influence research (e.g., Moscovici, Nemeth, external validity issues, real-world applications/limitations). Level descriptors: Level 4 (13-16 marks): AO1, AO2, and AO3 are well-balanced, accurate, and detailed. Evaluation is logical and application is precise. Level 3 (9-12 marks): Mostly accurate knowledge, reasonable application, and clear evaluation. Level 2 (5-8 marks): Some accurate knowledge, basic application, and limited evaluation. Level 1 (1-4 marks): Weak knowledge, minimal application, and little to no evaluation.

The behavioural explanation of phobias is based on Mowrer's (1960) two-process model, which proposes that phobias are acquired through classical conditioning and maintained through operant conditioning. According to classical conditioning, an individual associates a neutral stimulus (which initially causes no fear) with an unconditioned stimulus that naturally produces fear (unconditioned response). For example, in Watson and Rayner's (1920) 'Little Albert' study, a white rat (neutral stimulus) was paired with a loud noise (unconditioned stimulus), leading to a fear response (unconditioned response). Eventually, the white rat became a conditioned stimulus, producing a conditioned response of fear. Once acquired, phobias are maintained through operant conditioning. When an individual avoids the phobic stimulus, they experience a reduction in anxiety. This reduction in fear acts as negative reinforcement, strengthening the avoidance behaviour. Because the individual continuously avoids the phobic stimulus, they never have the opportunity to experience it without harm, thus preventing the extinction of the fear. A major strength of the two-process model is its practical application to therapy. It provides a clear rationale for exposure-based therapies, such as systematic desensitisation and flooding. By preventing avoidance behaviours and forcing the patient to face the phobic stimulus safely, these therapies help extinguish the conditioned fear, proving the model has high clinical utility. However, a significant limitation is that the model ignores cognitive aspects of phobias. Phobic individuals often experience cognitive distortions and irrational beliefs (e.g., thinking a harmless spider is deadly), which the purely behavioural model fails to explain. Furthermore, the model cannot explain why some phobias are incredibly common (e.g., heights, snakes) even in individuals who have never had a traumatic experience with them. Seligman (1971) suggested the concept of biological preparedness, arguing that humans are evolutionary predisposed to fear things that posed a threat to our ancestors, a factor the behavioural model overlooks.

AO1 (6 marks): Award up to 6 marks for knowledge of the two-process model (classical conditioning for acquisition, operant conditioning for maintenance via negative reinforcement, role of avoidance). AO3 (10 marks): Award up to 10 marks for evaluation. Credit points such as clinical application to behavioural therapies (systematic desensitisation, flooding), neglect of cognitive factors, biological preparedness (Seligman), and research limitations (e.g., not all phobias follow traumatic events). Level descriptors: Level 4 (13-16 marks): Knowledge is highly accurate and detailed. Evaluation is comprehensive, analytical, and well-structured. Level 3 (9-12 marks): Knowledge is mostly accurate. Evaluation is clear and mostly effective. Level 2 (5-8 marks): Knowledge has some gaps or inaccuracies. Evaluation is basic or limited. Level 1 (1-4 marks): Knowledge is weak or highly fragmented. Evaluation is minimal or absent.

Information from the left visual field (LVF) is projected to the right hemisphere of the brain. The right hemisphere is responsible for controlling the left side of the body, including the left hand. Since the hemispheres cannot communicate in a split-brain patient, the verbal left hemisphere cannot express what was seen in the LVF. However, the right hemisphere can guide the left hand to tactilely select the correct object (the key) without verbal awareness.

1 mark for selecting B. 0 marks for any other option.

A child in the concrete operational stage (typically aged 7 to 11 years) has developed the ability to conserve liquid and volume, understanding that quantity remains the same despite changes in physical appearance. However, systematic, abstract hypothesis testing (such as the scientific reasoning needed for the pendulum task) is characteristic of the formal operational stage, which they have not yet reached.

1 mark for selecting C. 0 marks for any other option.

An electroencephalogram (EEG) provides a general measure of brain activity, recording a mass of waves representing overall brain state. In contrast, Event-Related Potentials (ERPs) use statistical averaging techniques to filter out this background 'noise' or general brain activity. This allows researchers to isolate specific, millisecond-by-millisecond neural responses to a precise sensory, cognitive, or motor stimulus. Therefore, ERPs are highly specific and allow direct associations to be drawn between specific cognitive processes and neural activation, which is not possible with raw EEG recordings.

3 marks: A thorough and well-explained strength of ERPs over EEGs, demonstrating accurate understanding of statistical averaging/filtering background noise to isolate a specific response to a stimulus. 2 marks: A clear strength is identified and partially explained, but lacks some detail or clarity in the comparison. 1 mark: A vague strength is identified (e.g., 'it is more specific' or 'it measures response to a task') but not clearly explained or compared to EEGs. 0 marks: No creditworthy response.

Axonal sprouting is a key mechanism of functional recovery following brain injury. It occurs when undamaged axons grow new nerve endings (sprouts) to connect with other undamaged nerve cells. These new connections help to form alternative neural pathways or reconnect damaged pathways that were severed during the trauma. By bypassing the damaged areas, axonal sprouting allows the brain to functionally adapt and reorganise itself, thereby restoring lost cognitive or motor abilities.

3 marks: A clear, accurate, and detailed explanation of how axonal sprouting works (undamaged axons growing sprouts, establishing new/alternative neural pathways, and leading to functional recovery/restoring lost abilities). 2 marks: An explanation of axonal sprouting that includes some of the mechanism (e.g., growth of new connections) and links to recovery, but lacks precise terminology or full clarity. 1 mark: A basic description of axonal sprouting or recovery, but without explaining the process of how they connect and restore function. 0 marks: No creditworthy response.

In Vygotsky's theory of cognitive development, scaffolding refers to the temporary framework of support provided by a tutor, parent, or more knowledgeable peer to help a child perform a task. Initially, the support is high (e.g., direct instruction or breaking the task down into smaller steps). As the child's competence and confidence increase, this support is gradually withdrawn (faded). Scaffolding allows the child to successfully navigate through their Zone of Proximal Development (ZPD), moving from a state of guided performance to independent mastery of the cognitive skill.

3 marks: A clear and coherent outline of the role of scaffolding, explicitly defining it, explaining the gradual withdrawal/fading of support, and linking it to the child's progress through the ZPD or gaining independence. 2 marks: A clear outline of scaffolding but lacking one of the key elements (such as failing to mention the gradual withdrawal of support or the link to the ZPD). 1 mark: A vague definition of scaffolding as support or help given to a child, with no elaboration on how it aids development. 0 marks: No creditworthy response.

Piaget argued that infants do not understand that objects continue to exist when hidden (object permanence) until they are around 8 months old, as they do not search for a hidden toy before this age. However, Baillargeon used the violation of expectation (VOE) paradigm, showing infants 'possible' and 'impossible' physical events (e.g., a toy car rolling through a space where a block had been placed). She found that infants as young as 3 to 4 months looked significantly longer at the impossible event, indicating surprise. This suggests they possessed an innate expectation about the object's continued existence and solidity, thereby demonstrating object permanence much earlier than Piaget claimed.

3 marks: A clear, accurate explanation of how Baillargeon challenged Piaget, including Piaget's view of object permanence (8 months/search behavior), Baillargeon's VOE finding (longer looking at impossible events in younger infants), and the implication (object permanence is present earlier than 8 months). 2 marks: A mostly accurate explanation but lacking detail in either Piaget's baseline claim or the exact mechanism of the VOE task. 1 mark: A basic statement that Baillargeon found infants understand objects continue to exist younger than Piaget thought, but with no explanation of how this was demonstrated or what Piaget claimed. 0 marks: No creditworthy response.

A psychologist would conduct a pilot study (a small-scale trial run) for several reasons. Firstly, to check the clarity of standardized instructions: This ensures that participants understand what is required of them, allowing the researcher to modify confusing wording before the main study. Secondly, to test stimulus materials and procedures: For example, ensuring that a memory test is not too easy (avoiding a ceiling effect) or too difficult (avoiding a floor effect), which would render the results meaningless. Thirdly, to identify potential extraneous variables or practical issues: Such as timing constraints, equipment malfunctions, or researcher bias, allowing them to save time and money in the main study.

3 marks: Two clear, distinct, and well-explained reasons for conducting a pilot study in a laboratory experiment context. 2 marks: Two reasons identified, but only one is fully explained, or both are briefly explained without clear application. 1 mark: Only one reason is identified and explained, or two reasons are merely named without explanation. 0 marks: No creditworthy response.

An operationalised directional hypothesis must state the expected direction of the relationship/difference and clearly operationalise both the independent variable (IV) and the dependent variable (DV). Example of a fully operationalised directional hypothesis: 'Participants who are sleep-deprived (remaining awake for 24 consecutive hours) will recall significantly fewer words from a standard list of 20 nouns than participants who have had a normal night of sleep (a minimum of 8 hours of sleep).' This is directional because it predicts sleep deprivation will lead to worse performance (fewer words). The IV is operationalised as 24 hours awake vs 8 hours sleep, and the DV is operationalised as the number of words recalled from a list of 20 nouns.

3 marks: A clearly stated, directional (one-tailed) hypothesis with both variables (IV and DV) fully operationalised (e.g., specifying hours of sleep deprivation and the exact measure of memory, such as 'number of words recalled from a 20-word list'). 2 marks: A directional hypothesis where only one of the variables is operationalised, or a non-directional (two-tailed) hypothesis that is otherwise fully operationalised. 1 mark: A simple directional hypothesis with neither variable operationalised (e.g., 'sleep deprivation will make memory worse'). 0 marks: Failing to write a hypothesis (e.g., writing an aim) or writing a completely un-operationalised/null hypothesis.

Before the recital, Amara's sympathetic nervous system (SNS) is activated. The SNS is responsible for preparing the body for action during stressful situations (the 'fight or flight' response). This explains her physiological symptoms: her racing heart, sweaty palms, and shallow breathing, which occur as adrenaline is released. During the recital, as she begins to focus and relax, her parasympathetic nervous system (PNS) becomes dominant. The PNS acts as a 'rest and digest' system, working antagonistically to the SNS. It decreases her heart rate, slows her breathing, and stops sweat production, returning her body to its normal resting state (homeostasis).

Award 1 mark for each of the following points (up to 5 marks): 1) Identification of the sympathetic nervous system (SNS) as the system active before the recital. 2) Application to Amara's symptoms (e.g., explaining how SNS activation causes her racing heart, sweaty palms, or shallow breathing to prepare her for fight-or-flight). 3) Identification of the parasympathetic nervous system (PNS) as the system active during or after she starts playing. 4) Application to Amara's calming down (e.g., explaining how PNS activation reverses the stress response, lowering heart rate and normalizing breathing). 5) Explanation of the antagonistic relationship or the concept of homeostasis (how the two systems work in opposite ways to maintain physiological balance).

Vygotsky's theory highlights the Zone of Proximal Development (ZPD), which is the gap between what a child can do independently and what they can achieve with help. In this scenario, building the complex tower is within Maya's ZPD; she fails to do it alone, but succeeds with Dev's help. Dev provides scaffolding, which refers to the temporary, structured support given by a more knowledgeable other (MKO). Dev's scaffolding is both verbal (hinting to put wider blocks at the bottom) and physical (holding the base steady). Over time, as Maya internalizes these strategies, Dev will withdraw his support (a process known as fading), allowing Maya to eventually complete the task independently.

Award 1 mark for each of the following points (up to 5 marks): 1) Clear definition of the Zone of Proximal Development (ZPD). 2) Application of the ZPD to Maya (identifying that building the tower is beyond her current independent ability but achievable with Dev's assistance). 3) Clear definition of scaffolding (temporary support provided by a more knowledgeable other to help a child cross the ZPD). 4) Application of scaffolding to the scenario (identifying Dev's specific help, such as verbal hints about wider blocks or physical support holding the base). 5) Explanation of internalization or fading (how this support is temporary and will be gradually reduced as Maya masters the skill).

To implement a structured observation, Dr. Lin needs to define specific, objective behavioral categories before beginning. She can operationalise 'cooperative play' by breaking it down into observable, distinct actions. Examples include: 1) 'Sharing a toy/resource with another child' and 2) 'Taking turns during a structured game/activity'. For the sampling method, she could choose event sampling or time sampling. If she chooses event sampling, she would keep a continuous tally of every time one of the target cooperative behaviors occurs. This ensures that brief or infrequent cooperative behaviors are captured. Alternatively, if she chooses time sampling, she would observe the children at set intervals (e.g., every 2 minutes for 10 seconds) and record whether cooperative play is occurring. This reduces the cognitive demand on the observer but might miss behaviors occurring outside the intervals.

Award marks for the following points (up to 5 marks): 1 mark for explaining the nature of structured observation (i.e., using a pre-determined, structured behavioral checklist/categories to increase objectivity/reliability). 2 marks for providing two clearly operationalised behavioral categories appropriate for cooperative play in preschool children (1 mark per distinct, observable category, e.g., 'sharing a toy', 'verbally coordinating a task', 'taking turns on a slide'). 1 mark for explaining how either event sampling (counting each occurrence of target behaviors) or time sampling (recording behavior at pre-defined time intervals) would be executed in this scenario. 1 mark for applying a benefit or limitation of the chosen sampling method to this specific nursery context (e.g., 'event sampling is beneficial here because cooperative behaviors might be short-lived and would be missed in fixed-interval time sampling').

AO1: Plasticity refers to the brain's ability to modify its own structure and function as a result of experience and learning. During infancy, the brain experiences rapid growth in synaptic connections, peaking at around 15,000 per neuron at age 2 to 3 years. As we age, rarely used connections are deleted and frequently used connections are strengthened through synaptic pruning. Functional recovery refers to the transfer of functions from a damaged area of the brain to other undamaged areas following trauma. This occurs through structural changes including: axonal sprouting (the growth of new nerve endings which connect with other undamaged nerve cells to form new neuronal pathways), reformation of blood vessels, and recruitment of homologous (similar) areas on the opposite side of the brain to perform specific tasks. AO3: One strength is the practical application of this research to neurorehabilitation. Following injury, spontaneous recovery slows down, meaning physical therapy is needed to maintain progress. Techniques such as movement therapy and electrical stimulation are used to counter deficits in motor functioning, showing how understanding these processes improves quality of life. However, brain plasticity can also have maladaptive consequences. For example, prolonged drug use can lead to poorer cognitive functioning and an increased risk of dementia in later life. Also, 60 percent to 80 percent of amputees experience phantom limb syndrome, which is often painful and thought to be due to cortical reorganisation in the somatosensory cortex. Another point is that the capacity for neural reorganising is not fixed and can vary with age. Although plasticity is generally greater in children, research has shown that even older adults can demonstrate change when learning new skills, such as playing a musical instrument. Finally, cognitive reserve plays a role; Schneider et al. (2014) found that patients with a college education were seven times more likely to be disability-free one year after a moderate-to-severe brain injury compared to those who did not finish high school.

Level 4 (13-16 marks): Knowledge of brain plasticity and functional recovery is accurate and detailed. The discussion is thorough, effective, and well-structured, showing a clear understanding of physiological processes and evaluation. Level 3 (9-12 marks): Knowledge is mostly accurate with some detail. The discussion is mostly effective, though some points may lack depth. Level 2 (5-8 marks): Some knowledge is present but lacks detail. The discussion is limited, descriptive, or lacks focus. Level 1 (1-4 marks): Knowledge is very basic or fragmented. Discussion is absent, highly superficial, or irrelevant.

AO1: Vygotsky's theory emphasizes the crucial role of social interaction and culture in cognitive development. He argued that children are born with elementary mental functions (such as attention and sensation) which are transformed into higher mental functions (such as mathematical thinking) through cultural tools. A key concept is the Zone of Proximal Development (ZPD), which is the distance between what a child can achieve independently and what they can achieve with the guidance and encouragement of a More Knowledgeable Other (MKO). Another key concept is scaffolding, which refers to the temporary support structure provided by an adult or peer to help the child master a task, which is gradually removed as the child becomes more competent. Language is also central; private speech transitions into silent inner speech, driving cognitive self-regulation. AO3: One strength is empirical support for the concept of scaffolding. Wood and Middleton (1975) observed mothers teaching their 4-year-olds to assemble a 3D toy. They found that the most successful mothers adjusted their level of help depending on the child's success, demonstrating scaffolding in action. Another strength is the theory's positive educational applications, such as collaborative learning, peer tutoring, and reciprocal teaching in classrooms, which have been shown to improve learning outcomes. However, Vygotsky's theory has been criticized for underemphasizing individual differences and biological factors. It assumes that the processes of learning are largely the same across all children and ignores genetic influences on intelligence and development. Furthermore, unlike Piaget, Vygotsky did not provide a detailed, stage-by-stage account of development, making his concepts harder to test empirically.

Level 4 (13-16 marks): Knowledge of Vygotsky's theory is accurate and detailed. The discussion is thorough, effective, and well-structured, demonstrating a clear understanding of ZPD, scaffolding, and relevant research evidence. Level 3 (9-12 marks): Knowledge is mostly accurate. The discussion is mostly effective, though some evaluation points may lack detail or clarity. Level 2 (5-8 marks): Some knowledge is present but lacks detail. The discussion is limited, basic, or highly descriptive. Level 1 (1-4 marks): Knowledge is very limited or fragmented. Discussion is absent or extremely weak.

Step 1: Calculate the mean for the group with visual aids:
\((12 + 14 + 15 + 11 + 13 + 16 + 14 + 15) / 8 = 110 / 8 = 13.75\)

Step 2: Calculate the mean for the group without visual aids:
\((9 + 11 + 10 + 8 + 12 + 11 + 9 + 10) / 8 = 80 / 8 = 10.00\)

Step 3: Calculate the percentage increase from 10.00 to 13.75:
\(\text{Percentage Increase} = \frac{13.75 - 10.00}{10.00} \times 100 = \frac{3.75}{10} \times 100 = 37.5\%\)

1 mark for calculating both mean values correctly (13.75 and 10.00).
1 mark for showing correct workings / formula for calculating percentage change: \(\frac{13.75 - 10}{10} \times 100\).
1 mark for the correct final answer of 37.5% or 37.50% (accept 37.5 without the percentage sign).

Step 1: Arrange the data in ascending order:
11, 12, 12, 13, 14, 14, 15, 16, 45

Step 2: Identify the middle value (the 5th value):
Median = 14 seconds.

Step 3: Explain why the median is preferred:
The score of 45 seconds is an extreme outlier (anomalous score) compared to the rest of the data. Because the mean uses all scores in its calculation, it is highly sensitive to outliers and would be skewed upwards (mean = 20.2 seconds). The median is unaffected by extreme scores and therefore provides a more representative measure of the central tendency of the group.

1 mark for calculating the correct median of 14 (or 14 seconds).
1 mark for identifying that the data contains an extreme value/outlier (45 seconds) or stating the data is skewed.
1 mark for explaining that the mean would be disproportionately affected/skewed upwards by this outlier, whereas the median remains unaffected, making it more representative.

Step 1: Calculate the duration of Deep Sleep:
\(480 \text{ minutes} - 96 \text{ minutes} - 240 \text{ minutes} = 144 \text{ minutes}\)

Step 2: Express the relationship as an unsimplified ratio of REM : Light : Deep:
96 : 240 : 144

Step 3: Simplify the ratio by dividing by the greatest common divisor (48):
\(96 / 48 = 2\)
\(240 / 48 = 5\)
\(144 / 48 = 3\)

Simplest ratio = 2 : 5 : 3

1 mark for calculating the correct duration of Deep Sleep as 144 minutes.
1 mark for setting up the unsimplified ratio correctly (96 : 240 : 144) or demonstrating a correct step of simplifying (e.g., dividing by a common factor like 12 to get 8 : 20 : 12).
1 mark for the final simplified ratio of 2 : 5 : 3 (or 2:5:3).

The correct answer is **a**. Light acts as an exogenous zeitgeber and is detected by specialized photoreceptors in the retina. This neural signal is transmitted along the retinohypothalamic tract to the suprachiasmatic nucleus (SCN), which is the master endogenous pacemaker. The SCN then sends inhibitory signals to the pineal gland, resulting in a decrease in the secretion of the hormone melatonin, which promotes wakefulness.

Award 1 mark for selecting the correct option (a). Zero marks for any other option.

The correct answer is **b**. By making the significance level more stringent (reducing it from \(p \le 0.05\) to \(p \le 0.01\)), the researcher requires much stronger evidence to reject the null hypothesis. This reduces the risk of committing a Type I error (rejecting a true null hypothesis, or a 'false positive'). However, because the threshold for significance is now much harder to reach, the researcher is more likely to fail to reject a false null hypothesis, thereby increasing the risk of a Type II error (a 'false negative').

Award 1 mark for selecting the correct option (b). Zero marks for any other option.

1 mark for identifying the SCN as the master pacemaker in the hypothalamus that generates a 24-hour circadian rhythm. 1 mark for explaining that the SCN controls the pineal gland to regulate melatonin secretion. 1 mark for explaining how light signals from the optic chiasm reset/entrain the SCN.

3 marks: A clear, accurate, and coherent explanation of how the SCN regulates the sleep-wake cycle, detailing its internal rhythm, connection to melatonin, and entrainment by light. 2 marks: A partially complete explanation, perhaps missing details on melatonin or light entrainment. 1 mark: A very basic outline of the SCN's role in sleep.

1 mark for defining Expressed Emotion (criticism, hostility, emotional over-involvement). 1 mark for explaining that high EE acts as an environmental stressor for the patient. 1 mark for linking high stress in a high-EE environment to an increased likelihood of patient relapse/re-hospitalisation.

3 marks: Clearly defines EE and explains its role as a major stressor leading to relapse in schizophrenia. 2 marks: Identifies EE and links it to relapse, but with some lack of clarity in explaining the mechanism (stress). 1 mark: Simple definition of EE or basic mention of relapse with no expansion.

1 mark for explaining familiarisation with the data (reading/re-reading the diaries). 1 mark for explaining the process of generating initial codes from text segments. 1 mark for explaining how codes are collated into broader, meaningful themes that represent the dataset.

3 marks: A clear, step-by-step explanation of how thematic analysis would be applied to the insomnia diaries, covering familiarisation, coding, and establishing themes. 2 marks: A general explanation of thematic analysis but lacking specific application to the scenario or missing a key step. 1 mark: A vague or incomplete description of coding/themes.

1 mark for stating that total sleep time decreases over the lifespan (from 16 hours in newborns to 6-7 hours in the elderly). 1 mark for stating that the proportion of REM sleep decreases significantly (from 50% in infancy to about 20% in adulthood). 1 mark for stating that slow-wave sleep (SWS) decreases or sleep becomes more fragmented in old age.

3 marks: Outlines changes in total sleep time, REM sleep, and sleep architecture (SWS/fragmentation) with accurate details across the lifespan. 2 marks: Outlines changes in at least two aspects but may lack developmental details or precision. 1 mark: Outlines only one change in sleep patterns over the lifespan.

1 mark for explaining hyperdopaminergia (excess dopamine in subcortical areas/mesolimbic pathway) and its link to positive symptoms. 1 mark for explaining hypodopaminergia (deficit of dopamine in the cortex/prefrontal cortex) and its link to negative symptoms. 1 mark for explicitly contrasting the two hypotheses in terms of dopamine activity levels, brain regions, or symptom types.

3 marks: Clear and accurate distinction between the two hypotheses, specifying the direction of dopamine activity, brain locations, and associated symptom types. 2 marks: Explains both hypotheses but lacks details on brain regions or specific symptom associations. 1 mark: Identifies high/low dopamine but fails to clearly distinguish them or relate them to schizophrenia symptoms.

Spielman’s 3P model explains insomnia through three interacting factors:

1. **Predisposing factors:** These are internal, stable vulnerabilities. In the scenario, Julian has a genetic predisposition to anxiety and a family history of sleep issues (his father also had severe sleep issues), which makes him naturally more susceptible to developing insomnia.
2. **Precipitating factors:** These are external events that trigger the onset of sleep problems. In Julian's case, the trigger was starting a highly stressful new job, which initiated his first sleepless nights.
3. **Perpetuating factors:** These are cognitive and behavioral habits that maintain the insomnia even after the precipitating stressor has resolved. For Julian, these are his clock-watching behaviors and cognitive worries ("worrying about how tired he will be the next day"), which heighten arousal and prevent sleep from returning to normal.

**[1 mark]** for identifying and applying the predisposing factor to Julian (genetic/family history of anxiety/sleep issues).
**[1 mark]** for identifying and applying the precipitating factor to Julian (the stress of starting a new job).
**[1 mark]** for identifying and applying the perpetuating factor to Julian (clock-watching and cognitive worrying about sleep deprivation).
**[2 marks]** for explaining the interaction: 1 mark for showing how these factors combine to transition from short-term to chronic insomnia, and 1 mark for clear, coherent application using details from the scenario.

*Note: Max 3 marks if there is no explicit application to the scenario.*

Amara's experiences can be explained by two key family dysfunction concepts:

1. **Double-Bind Theory (Bateson et al.):** Amara receives contradictory, incompatible messages from her mother. The verbal message is warm ("loves her dearly") but the non-verbal message is cold and rejecting (pulling away with a tense expression). When Amara notices this contradiction, her mother invalidates her feelings by calling her "too sensitive." This traps Amara in a "no-win" situation, leading to a distorted grasp of reality and contributing to positive symptoms like delusions or disorganized thinking.
2. **Expressed Emotion (EE):** The high level of negative emotion directed at Amara by her family (frequent shouting matches, hostility, and extreme criticism of her personal habits) represents a high-EE environment. High EE is a significant source of chronic stress, which can trigger the onset or relapse of schizophrenia in vulnerable individuals.

**[5 marks]** The candidate provides a detailed, coherent explanation that accurately defines and fully applies both double-bind theory and expressed emotion (EE) to Amara's case.
**[3-4 marks]** The candidate explains both concepts with some application to the scenario, though one concept may be explained in less detail; OR only one concept is exceptionally well-applied with clear links to schizophrenia.
**[1-2 marks]** The candidate provides a basic definition of family dysfunction concepts with little or no application to Amara, or the explanation is highly muddled.
**[0 marks]** No creditworthy response.

The correct test to use is the **Mann-Whitney U test**.

**Justifications:**
1. **Test of Difference:** The researcher is investigating a difference in deep sleep hours between two groups rather than a correlation.
2. **Independent / Unrelated Design:** The study uses an independent groups design, comparing two distinct, non-overlapping groups of participants (Group A: night-shift workers and Group B: standard day-shift workers).
3. **Non-parametric / Ordinal Data:** Although hours of deep sleep is physically interval-level data, because it is highly skewed and violates parametric assumptions, a non-parametric alternative must be used, which treats the data at the ordinal level of measurement.

**[1 mark]** for identifying the Mann-Whitney U test.
**[1 mark]** for justifying that it is a test of **difference** and applying this to the scenario (comparing deep sleep hours between groups).
**[1 mark]** for justifying that it uses an **independent/unrelated design** and applying this to the scenario (comparing Group A/night-shift workers to Group B/standard day-shift workers).
**[1 mark]** for justifying that the data must be treated as **non-parametric/ordinal** because the interval sleep data is highly skewed/violates parametric assumptions.
**[1 mark]** for clear, coherent structure and expression linking all elements together accurately.

*Note: Do not award justification marks if the incorrect statistical test is identified, unless the justifications logically follow a minor naming error (e.g. "Mann-Whitney").*

Evolutionary (or ecological) explanations of sleep propose that sleep is an adaptive behavioral response that has evolved to increase an organism's chances of survival in its specific environmental niche. Webb's 'Energy Conservation' (or hibernation) theory suggests that sleep evolved to conserve energy during periods when foraging for food is inefficient or dangerous, such as at night for diurnal animals. Since body temperature and metabolic rate drop during sleep, energy is preserved. Meddis' 'Predator Avoidance' (or waste of time) theory posits that sleep keeps animals safe from predators. By remaining silent, still, and hidden during times of greatest danger (such as darkness), animals are less likely to be detected. Research by Allison and Cicchetti (1976) supports these evolutionary models, showing that species facing high danger (e.g., rabbits) sleep less deeply or in shorter bouts, while large predators (e.g., lions) sleep for long periods. Evaluation points: A major limitation of Meddis' theory is the 'unprepared organism' paradox: an animal that is unconscious for several hours is highly vulnerable to predators, which seems maladaptive if survival is the primary goal. Contrastingly, restoration theories (e.g., Oswald, Horne) argue that sleep is essential for physical and psychological repair, pointing to biological evidence like the release of growth hormone during slow-wave sleep. Evolutionary explanations also struggle to account for the catastrophic physiological consequences of long-term sleep deprivation (such as immune system failure and death in rats), which suggests sleep is a physiological necessity rather than just a convenient behavioral strategy. Lastly, animal research in this area lacks ecological validity as lab-based sleep environments do not mirror natural habitats, making generalizability difficult.

AO1 (6 marks): Award up to 6 marks for knowledge and understanding of evolutionary explanations of sleep. Examiners should look for clear descriptions of Webb's energy conservation theory and/or Meddis' predator avoidance theory, and relevant animal studies (e.g., Allison and Cicchetti). AO3 (10 marks): Award up to 10 marks for evaluation, analysis, and discussion. This includes: - Critically analyzing the adaptive value of sleep (the vulnerability paradox). - Comparing evolutionary explanations with restoration explanations (Oswald, Horne). - Methodological evaluation of animal studies (generalisability, ecological validity). - Discussion of the consequences of sleep deprivation as a challenge to evolutionary accounts. Mark Bands: Levels of Response: Level 4 (13-16 marks): Accurate and detailed knowledge; thorough and effective evaluation; clear, coherent structure. Level 3 (9-12 marks): Mostly accurate knowledge; some effective evaluation; mostly structured. Level 2 (5-8 marks): Limited/basic knowledge; superficial evaluation; lacks structure. Level 1 (1-4 marks): Very limited knowledge; little or no evaluation; disorganized.

Cognitive explanations of schizophrenia focus on dysfunctional thought processing and cognitive deficits. Frith (1992) identified two main types of dysfunctional thought processing that contribute to schizophrenic symptoms: metarepresentation and central control. Metarepresentation is our cognitive ability to reflect on thoughts, behaviors, and intentions, allowing us to distinguish our own thoughts from those of others. A deficit in metarepresentation means individuals cannot recognize their own thoughts and actions as self-generated, leading to positive symptoms like auditory hallucinations (hearing their own inner speech as an external voice) and delusions of control. Central control is the cognitive ability to suppress automatic responses while performing deliberate actions. A deficit in central control means individuals cannot filter out irrelevant thoughts and sensory stimuli, leading to speech derailment, disorganized thinking, and the 'word salad' characteristic of schizophrenia. Evaluation points: There is strong empirical support for cognitive deficits. For example, Stirling et al. (2006) compared 30 patients with schizophrenia with 18 control participants on a range of cognitive tasks, including the Stroop Test (which tests central control by requiring participants to suppress automatic reading). They found that schizophrenic patients took over twice as long as controls to name the ink colors, supporting Frith's theory of central control deficit. However, a major limitation of cognitive explanations is that they only explain the proximal causes of schizophrenia (the cognitive mechanisms that generate symptoms) rather than the distal causes (what actually causes these cognitive deficits in the first place). As such, they are often considered descriptive rather than explanatory. To address this, an interactionist approach is needed, combining cognitive explanations with biological factors, such as excess dopamine activity or neural correlates, which may drive these cognitive impairments. Success of cognitive-behavioral therapy for psychosis (CBTp) further supports the model, as helping patients challenge and restructure their dysfunctional thoughts leads to clinically significant reductions in symptom distress.

AO1 (6 marks): Award up to 6 marks for knowledge and understanding of cognitive explanations of schizophrenia. Examiners should look for explanations of dysfunctional thought processing, particularly Frith's concepts of metarepresentation deficits and central control deficits, and how they relate to positive/disorganized symptoms. AO3 (10 marks): Award up to 10 marks for evaluation, analysis, and discussion. This includes: - Evaluating empirical evidence (e.g., Stirling et al.'s Stroop test performance). - Addressing the limitation of proximal vs distal explanations (descriptive vs causal). - Integrating biological explanations to form a holistic/interactionist view (diathesis-stress model). - Utilizing the effectiveness of CBTp as supportive practical evidence for the cognitive model. Mark Bands: Levels of Response: Level 4 (13-16 marks): Accurate and detailed knowledge; thorough and effective evaluation; clear, coherent structure. Level 3 (9-12 marks): Mostly accurate knowledge; some effective evaluation; mostly structured. Level 2 (5-8 marks): Limited/basic knowledge; superficial evaluation; lacks structure. Level 1 (1-4 marks): Very limited knowledge; little or no evaluation; disorganized.

Step 1: Calculate the mean nightly sleep duration before the intervention.
\(\text{Sum Before} = 360 + 400 + 320 + 440 + 380 = 1900\text{ minutes}\)
\(\text{Mean Before} = 1900 / 5 = 380\text{ minutes}\)

Step 2: Calculate the mean nightly sleep duration after the intervention.
\(\text{Sum After} = 420 + 410 + 390 + 430 + 400 = 2050\text{ minutes}\)
\(\text{Mean After} = 2050 / 5 = 410\text{ minutes}\)

Step 3: Calculate the percentage increase from before to after.
\(\text{Increase} = 410 - 380 = 30\text{ minutes}\)
\(\text{Percentage Increase} = \left(\frac{30}{380}\right) \times 100 \approx 7.8947...\%\)

Step 4: Round to two decimal places.
\(\text{Percentage Increase} = 7.89\%\)

* **1 mark** for calculating both mean values correctly (Mean Before = 380 and Mean After = 410).
* **1 mark** for showing the correct formula/workings for calculating percentage increase: \(\frac{410 - 380}{380} \times 100\) (or equivalent).
* **1 mark** for the correct final answer rounded to two decimal places (accept 7.89% or 7.89).

Step 1: Understand that a complete pie chart represents 360 degrees, and the total number of patients is 60.

Step 2: Calculate the degrees per patient:
\(360^{\circ} / 60 = 6^{\circ}\text{ per patient}\)

Step 3: Calculate the angle for Auditory hallucinations:
\(36 \text{ patients} \times 6^{\circ} = 216^{\circ}\)

Step 4: Calculate the angle for Somatic/Tactile hallucinations:
\(9 \text{ patients} \times 6^{\circ} = 54^{\circ}\)

* **1 mark** for showing a correct method/workings to calculate sector angles (e.g., dividing the individual frequency by 60 and multiplying by 360, or finding that each patient equals \(6^{\circ}\)).
* **1 mark** for the correct angle for Auditory hallucinations (\(216^{\circ}\) or 216).
* **1 mark** for the correct angle for Somatic/Tactile hallucinations (\(54^{\circ}\) or 54).

Step 1: Identify the formula for degrees of freedom in a Chi-Square test of association:
\(df = (r - 1) \times (c - 1)\)
where \(r\) is the number of rows and \(c\) is the number of columns in the contingency table.

Step 2: Identify the number of rows and columns from the study:
* Rows (Sleep quality): 3 categories (Good, Average, Poor)
* Columns (Employment status): 3 categories (Employed, Unemployed, Retired)

Step 3: Substitute the values into the formula:
\(df = (3 - 1) \times (3 - 1)\)
\(df = 2 \times 2 = 4\)

* **1 mark** for stating the correct formula: \(df = (r - 1) \times (c - 1)\) or \(df = (\text{rows} - 1) \times (\text{columns} - 1)\).
* **1 mark** for showing the correct calculation/substitution: \((3 - 1) \times (3 - 1)\) or \(2 \times 2\).
* **1 mark** for the correct final degrees of freedom value (4).

The correct option is B. The psychologist is using an idiographic approach because the focus is on understanding the unique, subjective experiences of a very small number of individuals (three participants) without aiming to formulate general laws of behaviour. A primary limitation of the idiographic approach is that, due to the very small and unrepresentative sample size, it is highly restricted in its ability to generalise findings to the wider population.

Award 2 marks for selecting the correct option (B). Award 0 marks for any other response.

The correct option is B. By changing the job from writing disconnected blocks of code to completing an entire, functional module from start to finish, the developers can now identify with a complete and visible piece of work. This directly increases 'Task identity'. According to the Job Characteristics Model, high task identity (along with skill variety and task significance) contributes directly to the critical psychological state of 'experienced meaningfulness of the work'.

Award 2 marks for selecting the correct option (B). Award 0 marks for any other response.

According to the humanistic approach (specifically Carl Rogers), healthy self-esteem is fostered by unconditional positive regard—feeling loved and accepted without reservation.
When parents set boundaries on their love (e.g., 'I will only love you if you get high grades' or 'if you behave quietly'), they establish conditions of worth.
The child internalises these conditions, believing they are only valuable when they meet these standards.
This creates incongruence: a discrepancy between how they see themselves (actual self) and who they feel they must be to receive love (ideal self). This incongruence is what manifests as low self-esteem and anxiety.

2 marks: Outline of conditions of worth.
- 1 mark for explaining that conditions of worth arise from conditional positive regard (limits set on love/acceptance).
- 1 mark for elaborating that the child believes they must meet these conditions to be valued.

2 marks: Application to self-esteem/congruence.
- 1 mark for identifying that this process leads to incongruence (a mismatch between the actual self-concept and the ideal self).
- 1 mark for linking this incongruence to the development of low self-esteem or poor psychological well-being.

The idiographic approach focuses on the individual case as a means of understanding behaviour. Its primary strength is the depth of detail it produces, which can challenge existing general theories or prompt new areas of research.

The nomothetic approach focuses on identifying general principles of behaviour across groups. Its primary strength lies in its scientific utility, enabling researchers to establish baselines, predict outcomes, and generalise findings to formulate standardized treatments or interventions.

2 marks for explaining one strength of the idiographic approach:
- 1 mark for identifying a valid strength (e.g., rich/detailed qualitative data, focus on unique subjective experience, power to challenge general theories).
- 1 mark for explaining/elaborating why this is a strength in research.

2 marks for explaining one strength of the nomothetic approach:
- 1 mark for identifying a valid strength (e.g., scientific credibility, standardisation, ability to generalise/predict behaviour).
- 1 mark for explaining/elaborating why this is a strength in research.

Hackman and Oldham's Job Characteristics Model identifies five core job dimensions that affect work outcomes. To increase motivation, a company can focus on:
- Skill Variety: The degree to which a job requires different activities and talents. If a worker uses multiple skills, they find the work more meaningful.
- Task Identity: The degree to which a job requires completion of a whole and identifiable piece of work.
- Task Significance: The degree to which the job has a substantial impact on the lives or work of other people.
- Autonomy: The degree of freedom, independence, and discretion in scheduling and determining how to carry out the work. This fosters a sense of personal responsibility.
- Feedback: The degree to which carrying out work activities results in direct and clear information about performance.

For each of the two selected core job characteristics (max 2 marks each):
- 1 mark for identifying and outlining a correct core job characteristic from the model (Skill variety, Task identity, Task significance, Autonomy, Feedback).
- 1 mark for explaining how it relates to psychological states or directly increases employee motivation.

Leo's behaviour of insisting everything is fine and refusing to admit he is worried constitutes denial. Denial is an unconscious defense mechanism where the ego blocks external events or facts from conscious awareness. If a situation is too much to handle, the person just refuses to experience it. In Leo's case, denying the academic pressure protects his ego from anxiety and potential feelings of inadequacy, allowing him to maintain psychological equilibrium in the short term, even if it is maladaptive in the long term.

1 mark: Correctly identifying the defense mechanism as 'denial'.
1 mark: Explaining the nature of denial (refusing to acknowledge or accept reality/external threats).
2 marks: Explaining how this helps Leo cope with stress (e.g., protects the ego from painful anxiety/feelings of failure, prevents conscious distress by redirecting focus to pleasant activities like video games, temporarily keeps the psyche balanced).

According to Charles Handy's cultural types:
- Power culture (represented by a web): Power radiates from a central hub. Decisions can be made very quickly, but this relies heavily on the capabilities of those at the centre.
- Task culture (represented by a net/matrix): Focus is on getting a specific job done. Teams are formed for specific projects and then disbanded. Influence is based on expertise rather than position or personal power.

2 marks: Explanation of power culture (1 mark for identifying concentration of power in a single central figure/small group, 1 mark for highlighting its characteristics like rapid decision-making or low formal structure).
2 marks: Explanation of task culture (1 mark for identifying project/team orientation, 1 mark for highlighting that power is distributed based on task expertise rather than hierarchical status).

Note: For full marks, there must be a clear point of distinction between the two (e.g., centralized vs. distributed expertise-based power).

Biological explanation:
- Sarah's physiological symptoms (racing heart and sweating palms) are the result of biological mechanisms. When she is faced with public speaking, her brain perceives a threat, activating her hypothalamus-pituitary-adrenal (HPA) axis and the sympathetic nervous system. This triggers the release of adrenaline, preparing her body for a 'fight or flight' response.

Cognitive explanation:
- Sarah's fear is mediated by internal mental processes and memory. She has stored a negative schema of public speaking based on her past experience of being laughed at. When faced with a new presentation, she retrieves this negative memory, which distorts her current information processing (cognitive bias), leading her to expect negative outcomes and experience anxiety.

Biological explanation (2 marks):
- 1 mark for identifying a relevant biological mechanism (e.g., sympathetic nervous system activation, adrenaline release, fight-or-flight response).
- 1 mark for applying this mechanism directly to Sarah's physiological symptoms (her racing heart or sweating palms).

Cognitive explanation (2 marks):
- 1 mark for identifying a relevant cognitive concept (e.g., internal mental processes, schemas, memory retrieval, cognitive bias/distortions).
- 1 mark for applying this concept to Sarah's situation (e.g., how her memory of being laughed at in school shapes her current expectations or thoughts about public speaking).

Identification:
- Dr. Al-Sudani is adopting the idiographic approach to investigation.

Differences from the alternative approach (nomothetic approach):
- The idiographic approach focuses on the individual as a unique entity, using qualitative methods (such as Dr. Al-Sudani's unstructured interviews) to gain deep insights into their subjective experiences.
- In contrast, the alternative is the nomothetic approach, which seeks to establish general laws or principles of human behaviour. In the context of depression, a nomothetic researcher would study large samples of people using quantitative methods (e.g., standardised diagnostic questionnaires like the Beck Depression Inventory) to identify universal patterns or biological causes of depression across populations, rather than focusing on a single individual's unique life history.

- 1 mark for identifying the idiographic approach.
- 1 mark for applying/explaining why Dr. Al-Sudani's work is idiographic (e.g., focusing on unique, subjective experiences of individual patients using qualitative unstructured interviews).
- 1 mark for identifying the alternative approach as the nomothetic approach and defining its core feature (seeking to establish general laws/principles of behaviour).
- 1 mark for applying the difference to depression (e.g., explaining that a nomothetic approach would use large-scale quantitative data, such as standardised diagnostic questionnaires, to classify or find general causes of depression across a sample).

Stressor 1: Lack of control
- Research into workplace stress (e.g., the Whitehall studies, Johansson et al.) indicates that a lack of control over one's work environment is a major predictor of stress-related illness. George has a severe lack of control because he has 'no say over his shift patterns, break times, or the speed of the line,' leaving him unable to regulate his pace of work, which leads to chronic physiological arousal and illness.

Stressor 2: High workload / job demands
- High workload and fast-paced, repetitive tasks put high psychological and physical demands on an employee. George's job involves 'repetitive packaging tasks' on a conveyor belt moving at a 'fixed, fast speed.' This continuous, intense work demand exceeds his coping resources, directly contributing to his high anxiety and physical symptoms.

For each of the two stressors (2 marks each):
- 1 mark for identifying a relevant workplace stressor (e.g., lack of control, high workload / demands, repetitive work environment).
- 1 mark for applying this stressor to George's scenario (e.g., linking lack of control to having no say over shifts/breaks/conveyor belt speed; linking workload/demands to the fast, fixed speed of the line or repetitive packaging tasks).

### **AO1: Knowledge and Understanding (6 marks)**
Candidates should describe the key assumptions and concepts of the psychodynamic approach.

* **The Role of the Unconscious:** The mind is divided into three parts: the conscious, preconscious, and unconscious. Unconscious drives, instincts, and repressed childhood traumas exert a powerful influence over adult behaviour and personality.
* **Tripartite Structure of Personality:** The personality consists of:
- **The Id:** Operates on the pleasure principle; present at birth; demanding and selfish.
- **The Ego:** Operates on the reality principle; develops in early childhood; acts as a mediator between the competing demands of the Id and Superego.
- **The Superego:** Operates on the morality principle; represents internalized societal and parental values.
* **Defense Mechanisms:** Used by the Ego to manage anxiety caused by conflicts between the Id and Superego. Examples include:
- *Repression:* Forcing distressing memories out of the conscious mind.
- *Denial:* Refusing to acknowledge some aspect of reality.
- *Displacement:* Transferring feelings from the true source of distressing emotion onto a substitute target.
* **Psychosexual Stages of Development:** Children progress through five distinct developmental stages (Oral, Anal, Phallic, Latent, Genital). Unresolved conflicts at any stage lead to fixation, affecting adult personality (e.g., anal-retentive personality).

### **AO3: Comparison and Evaluation (10 marks)**
Candidates must compare the psychodynamic approach with the humanistic approach, highlighting similarities and/or differences.

* **Free Will vs. Determinism:**
- *Psychodynamic Approach:* Highly deterministic (psychic determinism). It claims that all behaviour is determined by unconscious motives and unresolved early childhood experiences, leaving no room for free will.
- *Humanistic Approach:* Strongly advocates for free will. It views individuals as active agents who have conscious control over their choices and behaviour, self-determining their destiny.
* **View of Human Nature:**
- *Psychodynamic Approach:* Pessimistic and negative. It views humans as inherently driven by primitive, biological impulses (aggression and sexual drives) that must be constantly controlled and suppressed.
- *Humanistic Approach:* Optimistic and positive. It views individuals as fundamentally good and possesses an innate drive toward growth, fulfillment, and self-actualisation.
* **Methodology and Scientific Status:**
- *Psychodynamic Approach:* Relies on idiographic clinical case studies (such as the case of Little Hans) to gather rich, qualitative data, but interprets these findings subjectively. It is criticized for being unfalsifiable and unscientific (concepts like the unconscious cannot be empirically tested).
- *Humanistic Approach:* Also adopts an idiographic, qualitative stance, rejecting scientific reductionism and objective, nomothetic testing. However, it focuses on conscious subjective experience rather than unconscious forces, although it is similarly criticized for lacking empirical testability.
* **Therapeutic Application:**
- *Psychodynamic Therapy (Psychoanalysis):* Highly directive. The therapist acts as the expert who interprets the patient's free associations, dreams, and resistance to uncover unconscious conflicts.
- *Humanistic Therapy (Person-Centred Therapy):* Non-directive. The therapist acts as a facilitator, providing a warm, supportive, and non-judgmental environment based on unconditional positive regard, empathy, and genuineness to help the client achieve congruence.

### **AO1 (6 marks)**
* **5–6 marks:** Knowledge and understanding of the psychodynamic approach is detailed, accurate, and coherent, showing a clear grasp of its core concepts (e.g., role of the unconscious, personality structure, defense mechanisms, and psychosexual stages).
* **3–4 marks:** Knowledge of the psychodynamic approach is mostly accurate and clear, though some details or explanations may be omitted or lack depth.
* **1–2 marks:** Knowledge of the approach is weak, disjointed, or highly limited. Core terms may be used incorrectly.
* **0 marks:** No relevant content.

### **AO3 (10 marks)**
* **9–10 marks:** Comparison between the psychodynamic and humanistic approaches is well-developed, highly structured, and balanced. Points of contrast (e.g., determinism vs. free will, view of human nature, methodology, and therapy) are clearly articulated and thoroughly evaluated.
* **6–8 marks:** Comparison is clear and mostly balanced. Evaluation points are logical and well-explained, though some aspects may lack depth or detail.
* **3–5 marks:** The comparison is limited, basic, or highly descriptive. The candidate may focus heavily on describing both approaches separately with very little direct comparative analysis.
* **1–2 marks:** Very weak comparison. Explanations are superficial, fragmented, or largely irrelevant.
* **0 marks:** No comparative analysis or evaluation is present.

### **AO1: Knowledge and Understanding (6 marks)**
Candidates should define and describe the features of both the idiographic and nomothetic approaches.

* **Idiographic Approach:**
- Focuses on the unique, subjective experience of the individual.
- Aims to understand private experiences rather than formulating general rules or laws of behaviour.
- Typically utilizes qualitative research methods, such as case studies, unstructured interviews, diaries, and thematic analysis.
- High interest in individual clinical history and phenomenological reality.
* **Nomothetic Approach:**
- Aims to establish general laws and principles of human behaviour that apply across populations.
- Typically utilizes quantitative research methods, including structured observations, laboratory experiments, large-scale surveys, and psychometric testing.
- Focuses on finding similarities across groups of people to allow for prediction and control of behaviour.
* **Integration of Examples (at least two areas):**
- *Biological / Psychopathology Area:* The biological approach uses the nomothetic framework to determine general laws regarding neurotransmitter imbalances in mental illness (e.g., OCD caused by low serotonin, treated with SSRIs). Conversely, neuropsychological research often uses the idiographic approach (e.g., case studies like HM or Phineas Gage) to investigate brain injury effects on memory and executive functions.
- *Cognitive / Humanistic Area:* The cognitive approach heavily uses a nomothetic approach to model general information processing models (e.g., Multi-Store Model of Memory) across populations, while the Humanistic approach is strictly idiographic, focusing entirely on the individual's progress toward self-actualisation (e.g., Rogers' client-centered therapy).

### **AO3: Evaluation and Synthesis (10 marks)**
Candidates must evaluate the strengths, limitations, and relationship between the two approaches.

* **Scientific Rigor vs. Subjectivity:**
- The nomothetic approach is highly scientific. The use of standardized procedures, statistical analysis, and objective measurements allows for replication, high control over confounding variables, and establishing cause-and-effect relationships.
- The idiographic approach is criticized for its subjective nature, small sample sizes (often \(N = 1\)), and vulnerability to researcher bias, meaning findings cannot be easily generalized to the wider population.
* **Depth of Understanding vs. Generalization:**
- The idiographic approach provides deep, rich, and holistic insights into the individual. This can challenge existing nomothetic theories or spark new pathways of research (e.g., the unique deficits of patient HM helped refine nomothetic models of memory by showing short-term and long-term memory use distinct structures).
- However, the nomothetic approach allows for broad, general rules which are useful for practical applications on a wider scale (such as standardized diagnostic manuals like DSM-5 and mass-market pharmacological treatments).
* **Complementarity / Integration:**
- Rather than viewing them as competing paradigms, modern psychology increasingly views them as complementary. A researcher might start with an idiographic case study to explore a novel phenomenon, then formulate a hypothesis to be tested using a nomothetic, large-scale experimental design.

### **AO1 (6 marks)**
* **5–6 marks:** Clear, accurate, and detailed knowledge of the idiographic and nomothetic approaches. Concepts are explained precisely with appropriate references to research methods. Relevant examples from at least two different areas of psychology are integrated effectively.
* **3–4 marks:** Accurate knowledge of both approaches is demonstrated, but there may be minor inaccuracies, omissions, or a lack of clarity in how examples are applied.
* **1–2 marks:** Basic or fragmented knowledge of the approaches. Examples are either absent, incorrect, or not linked to the approaches.
* **0 marks:** No relevant content.

### **AO3 (10 marks)**
* **9–10 marks:** High-quality, balanced, and critical evaluation of both approaches. Contrast between scientific rigor and depth of understanding is clearly explained. Discussion of how both approaches complement each other is sophisticated and thorough.
* **6–8 marks:** Clear evaluation is provided. Strengths and limitations of both approaches are discussed, and some analytical depth is achieved, though some points may be slightly underdeveloped.
* **3–5 marks:** The evaluation is weak, unbalanced, or highly descriptive. The candidate may outline the two approaches without analyzing their value, or omit critical evaluation of one approach.
* **1–2 marks:** Minimal evaluation. Discussion is extremely basic, lacking focus on key methodological debates.
* **0 marks:** No evaluative content.

### **AO1: Knowledge and Understanding (6 marks)**
Candidates should describe at least two theories of employee motivation. Suitable examples include Herzberg's Two-Factor Theory and Locke's Goal-Setting Theory (other valid theories include Maslow's Hierarchy of Needs, McClelland's Theory of Needs, Vroom's Expectancy Theory, or Equity Theory).

* **Herzberg's Two-Factor Theory:**
- Divides occupational satisfaction/motivation factors into two categories:
- *Hygiene Factors (Extrinsic):* Factors that do not actively motivate but must be present to prevent dissatisfaction (e.g., pay, job security, company policies, physical working conditions).
- *Motivators (Intrinsic):* Factors that actively drive job satisfaction and higher effort (e.g., achievement, recognition, responsibility, meaningful work, opportunities for advancement).
* **Locke's Goal-Setting Theory:**
- Argues that goal-setting is directly linked to task performance.
- Five core principles increase motivation and productivity:
- *Clarity:* Goals must be specific and measurable (SMART targets).
- *Challenge:* Challenging but attainable goals stimulate higher effort than easy goals.
- *Commitment:* The employee must accept and buy into the goal.
- *Feedback:* Regular progress reviews are essential to keep motivation high.
- *Task Complexity:* Goals must be realistic and broken down into manageable steps if complex.

### **AO3: Application and Evaluation (10 marks)**
Candidates should analyze the practical application of these theories to increase workplace productivity and critically evaluate their strengths and limitations.

* **Practical Applications for Workplace Productivity:**
- *Application of Herzberg's Theory:* Organizations cannot motivate staff simply by increasing salary (which is only a hygiene factor). To boost productivity, managers must engage in **Job Enrichment** (e.g., giving employees more challenging responsibilities and control over their work) and establish recognition systems (e.g., Employee of the Month, constructive public praise).
- *Application of Locke's Theory:* Organizations can implement formal systems like Management by Objectives (MBO), where managers work with employees to set clear, difficult targets and hold scheduled performance review meetings to provide direct feedback, which research shows significantly improves output.
* **Research Support:**
- Support for Locke's theory comes from numerous studies demonstrating that specific, hard goals lead to higher performance than 'do your best' instructions.
- Job enrichment programs based on Herzberg's theories have shown increases in worker productivity and reductions in absenteeism.
* **Limitations / Critique of the Theories:**
- *Herzberg's Theory:* Subject to attribution bias (people often attribute job satisfaction to their own internal efforts/motivators and dissatisfaction to external factors/hygiene factors). It also assumes a uniform reaction, ignoring individual differences (some workers prefer routine jobs with high pay over high-responsibility jobs).
- *Locke's Theory:* If goals are too difficult, they can lead to stress, burnout, and unethical shortcuts (e.g., falsifying numbers to hit targets). Goal-setting can also discourage cooperation if team members focus entirely on their individual targets rather than broader organizational goals.
- *Cultural Bias:* Many motivational theories are rooted in Western, individualistic cultures that highly value personal achievement and autonomy, which may not translate perfectly to collectivist cultures where group goals and harmony are more valued.

### **AO1 (6 marks)**
* **5–6 marks:** Detailed, accurate, and coherent explanation of at least two theories of employee motivation. Key terminology is used correctly, showing a thorough understanding of theoretical concepts.
* **3–4 marks:** Accurate description of two motivational theories, though there may be minor omissions, or one theory may be described with significantly more detail than the other.
* **1–2 marks:** Basic or disjointed descriptions. Only one theory is addressed adequately, or both are outlined with significant errors/omissions.
* **0 marks:** No relevant content.

### **AO3 (10 marks)**
* **9–10 marks:** Excellent analytical application of the chosen theories to improving workplace productivity. The evaluation is balanced, critical, and incorporates robust debates (e.g., individual differences, research support, methodological weaknesses, cultural bias).
* **6–8 marks:** Good discussion of how these theories apply to workplace settings. Evaluation is present and mostly balanced, though some points could be linked more explicitly to productivity or lack depth.
* **3–5 marks:** The application/evaluation is weak, brief, or highly superficial. The candidate might describe the theories in detail but fail to sufficiently discuss their practical implementation or limitations.
* **1–2 marks:** Very weak evaluation with little to no focus on applications to productivity. Points are fragmented and lack relevance.
* **0 marks:** No evaluative content.
