In Andrade's study, monitoring performance was measured using the number of correct names written down during the message, minus any false alarms. False alarms were names that were not on the target list or other random names mentioned. This resulted in a net monitoring score.

1 mark for identifying the baseline of correct names written down. 1 mark for stating that false alarms were subtracted. 0.5 marks for detailing what counted as a false alarm (e.g., names of people not attending the party, or writing down completely incorrect names).

To eliminate examiner bias, the experimenter only asked the participant standard questions like 'were you dreaming or not?' and did not engage in active conversation. Crucially, the participant spoke into a voice recorder or intercom so there was no direct face-to-face interaction that could convey expectations. Furthermore, a report was only classified as a 'dream' if the participant could describe the dream content in clear detail, rather than just guessing.

1 mark for describing the standardized questioning (asking 'were you dreaming or not?'). 1 mark for explaining the lack of face-to-face contact (use of intercom/recorder). 0.5 marks for specifying that a detailed description of dream content was required to prevent guessing.

In Fagen et al.'s study, positive reinforcement training (PRT) was utilized. The primary reinforcers were high-value food items like bananas or chopped sugar cane. A secondary reinforcer, such as a whistle blow or a clicker, was sounded immediately when the elephant performed the correct target behavior (e.g., lifting a foot) to bridge the time gap. Correct actions were rewarded, while incorrect actions were ignored without punishment.

1 mark for identifying the primary reinforcer (food rewards like bananas/sugar cane). 1 mark for identifying the secondary reinforcer (whistle/clicker) used to mark correct behavior. 0.5 marks for mentioning that incorrect responses were ignored or no negative reinforcement/punishment was used.

Hassett et al. categorized toys into two categories: wheeled toys (which are culturally considered masculine) and plush toys (culturally considered feminine). Examples of wheeled toys used in the trial include a construction truck, a police car, or a wagon. Examples of plush toys include a plush teddy bear, a plush dog, or a Raggedy Andy doll.

1 mark for naming both categories: wheeled (masculine) and plush (feminine). 1 mark for a correct example of a wheeled toy (e.g., truck, car, wagon). 0.5 marks for a correct example of a plush toy (e.g., teddy bear, Raggedy Andy doll, plush puppy).

The Feelings Distress Meter was a 9-point scale ranging from 0 (no distress) to 8 (maximum distress). At the beginning of therapy, the boy used it to rate different types of buttons to construct a hierarchy of fear. During exposure therapy and cognitive imagery sessions, the boy periodically rated his current level of distress upon encountering or imagining buttons, allowing the researchers to quantitatively track his progress and the reduction of his phobia.

1 mark for describing the scale's format (a 9-point self-report scale from 0 to 8 measuring distress). 1 mark for explaining its use in creating the fear/disgust hierarchy. 0.5 marks for explaining its use during the actual therapy sessions to monitor cognitive/exposure progress.

In the target-absent lineup condition, the actual target (the perpetrator from the video) was replaced by a foil matching the description. The lineup also included a wildcard choice (a silhouette with a question mark) indicating that the target is not there. The main purpose of this condition was to evaluate the rate of false identifications (false alarms) and to investigate developmental differences (children vs. adults) in the tendency to make a false choice when the culprit is not present.

1 mark for describing the contents of the target-absent lineup (foils matching description, target missing, and a wildcard/silhouette option). 1 mark for explaining its purpose (to measure false positive identification rates). 0.5 marks for linking it to developmental differences (e.g., investigating children's higher susceptibility to social pressure to make a choice).

The researchers utilized magnetic resonance imaging (MRI) to capture structural images of the participants' brains. Scans were administered at two intervals: once before the 8-week Mindfulness-Based Stress Reduction (MBSR) program, and once immediately following the program. They then applied Voxel-Based Morphometry (VBM) to quantify and statistically compare the gray matter concentration in targeted regions of interest (such as the hippocampus) as well as across the whole brain.

1 mark for stating that MRI scans were conducted at two specific points (pre-intervention/baseline and post-intervention/8 weeks later). 1 mark for identifying the analytical method, voxel-based morphometry (VBM), or measuring gray matter concentration/density. 0.5 marks for mentioning a specific anatomical region of interest analyzed (e.g., hippocampus, temporoparietal junction, cerebellum).

The Comfortable Interpersonal Distance (CID) paradigm was a computerized task where participants were presented with a schematic circle and asked to imagine themselves in the center. An avatar representing a specific social figure (such as a friend, a stranger, or an authority figure) or a non-social control (a ball) would approach from one of 8 different angles. The participant had to press a key to 'stop' the approaching figure at the exact point they would begin to feel uncomfortable. The distance remaining between the figure and the center of the circle was used to calculate their preferred personal space.

1 mark for explaining the computerized layout (participant in the center of a circle, imagining a figure approaching). 1 mark for describing the procedure (the figure approaches from one of 8 directions and the participant stops them using a key when they feel uncomfortable). 0.5 marks for stating how the measurement was calculated (remaining distance as a percentage or distance from the center).

1. Behavioral Exposure (Contingency Management): Dr. Aris would create an exposure hierarchy (e.g., starting with looking at small plastic zippers, progressing to touching plastic zippers, then looking at metal zippers, and finally touching and operating metal zippers). At each step, the child is praised and rewarded (positive reinforcement) for coping. 2. Imagery Exposure (Disgust Imagery): Dr. Aris would address the child's disgust cognitions. He would have the child imagine scenarios, such as zippers falling on them or touching them, and describe how they look and feel. The therapist would help the child pair these images with self-control and coping statements to change the cognitive appraisal of disgust. 3. Application rationale: Addressing both is essential because, as in Saavedra and Silverman's study, behavioral exposure may reduce distress/fear ratings, but disgust can remain high or even increase. Only when imagery exposure is introduced does the level of disgust/distress drop significantly over time.

Apply the following marking points (up to 5 marks total): - 1 mark for defining/explaining behavioral exposure / contingency management in the context of the study. - 1 mark for applying behavioral exposure to the zipper phobia scenario (e.g., step-by-step progress from viewing to touching metal zippers, paired with rewards). - 1 mark for defining/explaining imagery exposure / disgust cognitive restructuring in the context of the study. - 1 mark for applying imagery exposure to the zipper phobia scenario (e.g., imagining zippers touching the body, addressing the 'disgusting' sensory feel/smell of metal). - 1 mark for explaining the psychological reasoning behind using both (e.g., noting that behavioral exposure alone can increase disgust, which requires cognitive imagery therapy to resolve).

1. Finding 1 (Same-sex model influence): Bandura et al. found that children were more likely to imitate same-sex models (especially boys imitating physical aggression from male models). Application: Ms. Taylor can deploy male teaching assistants or older male student mentors to model cooperative, non-violent play on the playground, specifically targeting boys who are at higher risk of displaying physical aggression. 2. Finding 2 (Effect of non-aggressive models): The study showed that exposure to non-aggressive models significantly reduced the level of aggression displayed by children compared to the aggressive group. Application: Ms. Taylor can introduce designated 'prosocial leaders' on the playground who are trained to play cooperatively and calmly. By seeing these peaceful models, other children will naturally show lower levels of playground aggression. 3. Synthesis: Utilizing both gender-matching and proactive positive modeling provides a dual-layered intervention that directly mirrors the experimental conditions of Bandura et al.'s research.

Apply the following marking points (up to 5 marks total): - 1 mark for identifying a relevant finding from Bandura et al. regarding same-sex imitation or gender differences. - 1 mark for applying this finding to a concrete playground strategy (e.g., using male/female staff to model positive behaviors). - 1 mark for identifying a second relevant finding (e.g., the suppressive effect of a non-aggressive model on subsequent behavior). - 1 mark for applying this second finding to a playground strategy (e.g., peer mentoring, structured calm play zones). - 1 mark for maintaining a clear focus on the transmission of aggression paradigm and providing a detailed, practical explanation of how these reduce aggressive behaviors.

According to the cost-reward model proposed by Piliavin et al., bystanders calculate the costs and rewards of both helping and not helping before choosing a response to reduce their unpleasant arousal. 1. Reducing the costs of helping: The company can place clear, step-by-step instructions and automated external defibrillators (AEDs) on trains. This reduces the cost of effort, embarrassment, or physical risk of doing the wrong thing. 2. Increasing the costs of not helping: The company can run campaigns highlighting passenger solidarity (e.g., 'We look out for each other'). This increases internal costs (guilt, self-blame) and external costs (social disapproval from other passengers) if someone ignores a person in need. 3. Increasing the rewards of helping: The company can launch a 'Local Hero' award scheme that publicly praises and rewards passengers who assist in emergencies, adding a tangible positive reward to helping. 4. Decreasing the rewards of not helping: They can design train carriages with open walkthroughs, making it physically harder for bystanders to 'escape' the emergency scene (i.e., avoiding the situation by changing carriages, which is a common way to reduce arousal without helping).

Apply the following marking points (up to 5 marks total): - 1 mark for explaining how reducing the costs of helping (e.g., ease of action, safety) increases helping behavior, with a valid transport example. - 1 mark for explaining how increasing the costs of not helping (e.g., moral guilt, social censure) increases helping behavior, with a valid transport example. - 1 mark for explaining how increasing the rewards of helping (e.g., praise, social approval) encourages action, with a valid transport example. - 1 mark for explaining how decreasing the rewards of not helping (e.g., preventing cognitive avoidance/escape) forces action, with a valid transport example. - 1 mark for explicitly showing how these strategies collectively work to resolve the unpleasant bystander arousal caused by witnessing an emergency, reflecting Piliavin's model.

1. Application of Procedure: Dr. Chen should provide students with an optional, pre-printed or downloadable sheet containing geometric shapes (e.g., rows of circles and squares) to shade. He should instruct them to shade the shapes while listening, emphasizing that neatness does not matter. This mirrors Andrade's controlled doodling condition rather than letting students do free/creative doodling. 2. Avoidance of Creative Doodling: He must caution students against drawing complex, original illustrations, as this would draw away too much attention (dual-task interference). 3. Explanation of Effectiveness (Arousal & Daydreaming): This is effective because listening to a monotonous lecture can cause the mind to wander. Daydreaming consumes substantial cognitive resources. Doodling acts as a micro-task that maintains sufficient physiological arousal to keep the brain focused on the auditory input without overloading it. 4. Expected Outcome (Recall): Consistent with Andrade’s findings, where the doodling group recalled 29% more information (names and places) than the control group, Dr. Chen's students are expected to show significantly higher retention and recall of the lecture content.

Apply the following marking points (up to 5 marks total): - 1 mark for suggesting a structured doodling task (e.g., shading geometric shapes) rather than free drawing. - 1 mark for specifying the instructions given to the students (e.g., shade the shapes, neatness doesn't matter, avoid complex drawing). - 1 mark for explaining the underlying cognitive theory (e.g., maintaining optimal cortical arousal, preventing daydreaming/mind-wandering). - 1 mark for explaining that daydreaming uses valuable cognitive/executive resources, whereas structured doodling uses very little but keeps the person anchored. - 1 mark for linking the application to improved memory performance (e.g., citing Andrade's finding of a ~29% increase in information recall).

The study by Pozzulo et al. (2021) examined line-up identification in children (aged 4-17 divided into groups) and adults using cartoon and human targets.

### Ecological Validity
**Strengths (High Ecological Validity):**
- The researchers attempted to simulate a real-world eyewitness situation by having participants watch a video of a crime (a purse snatching for the human target condition) or a cartoon event (a scene from 'King of the Hill' with a cartoon target).
- The use of line-ups (both target-present and target-absent) closely mirrors the actual legal processes used by police forces globally when obtaining eyewitness identification.

**Weaknesses (Low Ecological Validity):**
- Watching a video clip is very different from witnessing a live crime in person. In real life, an eyewitness may feel intense fear, anxiety, or stress, which activates the physiological fight-or-flight response and can alter memory consolidation. In a controlled environment, these emotional elements are absent.
- The use of a cartoon target is highly artificial. In real forensic psychology, witnesses are never asked to identify a cartoon character in a line-up. Children and adults likely processed cartoon faces differently than human faces, making it difficult to generalise the cartoon findings to real criminal investigations.

### Quantitative Data
**Strengths:**
- The study collected purely quantitative data, measuring the percentage of correct identifications, correct rejections, and false positives in both target-present and target-absent conditions.
- This allowed the researchers to conduct objective statistical analyses (such as chi-square tests) to compare the performance of young children, older children, and adults.
- It also allowed for clear comparisons between the cognitive processing of human versus cartoon faces.

**Weaknesses:**
- Quantitative data lacks qualitative depth. It does not explain *why* children were significantly more likely than adults to make a false identification in the target-absent condition.
- It does not reveal whether children felt social pressure (such as demand characteristics or a desire to please the adult researcher) to choose someone from the line-up even when the target was not there, which limits our understanding of the underlying cognitive or social mechanisms.

**Marking Scheme (12 Marks):**

**Level 4 (10-12 marks):**
- Evaluation is detailed, comprehensive, and well-structured, addressing both ecological validity and quantitative data with balanced strengths and weaknesses.
- Direct, explicit, and accurate reference to Pozzulo et al. (e.g., referencing children vs. adults, target-present vs. target-absent line-ups, and the human vs. cartoon video clips).
- Demonstrates clear understanding of methodological terms.

**Level 3 (7-9 marks):**
- Good evaluation with some structure. Addresses both issues (ecological validity and quantitative data), but may focus more on one than the other.
- Good reference to the study, though some specific details might be missing or slightly vague.

**Level 2 (4-6 marks):**
- Basic evaluation of one or both issues.
- The response may be highly descriptive of the study's procedure rather than analytical.
- Limited reference to the study.

**Level 1 (1-3 marks):**
- Minimal evaluation, showing limited understanding.
- Very few or no relevant links to Pozzulo et al.

**Level 0 (0 marks):**
- No response worthy of credit.

The study by Hassett et al. (2008) investigated sex differences in toy preferences in rhesus monkeys to explore whether biological factors (nature) or socialization (nurture) drive these preferences.

### Ethical Considerations (Animal Research)
**Strengths (Adherence to Ethical Guidelines):**
- **Housing and Socialization:** The rhesus monkeys were kept in a large outdoor housing area with access to indoor areas. This social environment allowed them to live in a stable troop of 135 animals, avoiding isolation, which is highly distressing for primates.
- **Physical Welfare:** The monkeys had continuous access to water and were fed twice daily with monkey chow and fresh fruit. No food or water deprivation was used to motivate play behaviour.
- **Harm and Stress:** The study did not use any invasive surgical procedures, injections, or physical restraint. The monkeys were simply observed in their naturalistic enclosure playing with toys, ensuring low physical risk and distress.

**Weaknesses (Potential Ethical Issues):**
- **Captivity:** The monkeys were kept in captivity rather than being studied in their natural wild environment.
- **Introduction of Novel Objects:** Introducing novel toys (wheeled toys like trucks, and plush toys like Winnie-the-Pooh) could theoretically trigger territorial aggression or conflict among troop members over access to the resources, though researchers monitored and minimized this.

### Nature vs. Nurture Debate
**Contribution to Nature:**
- The study showed that male monkeys showed a clear, statistically significant preference for wheeled toys (masculine/systemising toys) over plush toys, while females showed a wider range of preferences. Since these monkeys had not experienced human socialization, media influence, or gender-typed parenting, these differences strongly support the 'nature' side of the debate.
- This suggests that sex differences in toy preferences have a biological basis, possibly due to prenatal hormone exposure (like testosterone) affecting visual preferences or active play styles.

**Contribution to Nurture (Limitations of Nature-only Explanation):**
- While the monkeys do not experience human socialization, they still live in a structured social environment with other monkeys where social learning (nurture) could occur.
- Younger monkeys might observe and mimic the play preferences of dominant or older troop members of the same sex.
- Furthermore, the female monkeys did not show a rigid preference for plush toys, exhibiting more flexible toy play. This flexibility suggests that interaction with objects is not entirely genetically determined and can be influenced by individual experience and immediate environment.

**Marking Scheme (12 Marks):**

**Level 4 (10-12 marks):**
- Evaluation is detailed, comprehensive, and well-structured, addressing both ethical considerations (animal guidelines) and the nature vs. nurture debate.
- Direct, explicit, and accurate reference to Hassett et al. (e.g., referencing rhesus monkeys, wheeled vs. plush toys, outdoor housing, and the lack of human socialization).
- Demonstrates clear understanding of psychological and ethical terminology.

**Level 3 (7-9 marks):**
- Good evaluation with some structure. Addresses both issues (ethics and nature/nurture), but may focus more on one than the other.
- Good reference to the study, though some specific details might be missing or slightly vague.

**Level 2 (4-6 marks):**
- Basic evaluation of one or both issues.
- The response may be highly descriptive of the study's procedure (e.g., lists of toys or troop details) rather than analytical.

**Level 1 (1-3 marks):**
- Minimal evaluation, showing limited understanding.
- Very few or no relevant links to Hassett et al.

**Level 0 (0 marks):**
- No response worthy of credit.

Counterbalancing is a technique designed to control order effects (like practice or fatigue) in repeated measures designs. This is done by splitting the participants so that half complete the tasks in one order (e.g., Condition A then B) and the other half complete them in the reverse order (Condition B then A).

1 mark: Explaining that the order of tasks or conditions is systematically varied/reversed for different groups of participants.
1 mark: Identifying the purpose, which is to control for or reduce order effects (such as fatigue, boredom, or practice).

A pilot study serves as a trial run of an experiment or investigation. It is conducted on a smaller sample size before the actual study begins to check if the procedures, apparatus, and instructions work as intended, allowing researchers to make necessary modifications.

1 mark: Stating that it is a small-scale, preliminary, or trial run of the research.
1 mark: Explaining its function (e.g., to identify design flaws, test materials, check equipment, or refine procedures before the full-scale study).

A controlled observation is characterized by the researcher manipulating or structuring the environment where the observation takes place (such as a laboratory room with a one-way mirror). The researcher standardises the setup to ensure consistent conditions for all participants.

1 mark: Stating that observation occurs in an environment that is structured, managed, or set up by the researcher.
1 mark: Explaining a feature of this method (e.g., standardisation of conditions, use of coded behavioral categories, or minimized environmental distractions).

Informed consent is a core ethical guideline. It requires researchers to fully explain the nature of the research to the participants before it begins. The participants then use this information to decide whether or not they want to take part of their own free will.

1 mark: Explaining that participants are given comprehensive information/details about what the study involves (including potential risks, procedures, or rights).
1 mark: Explaining that they voluntarily agree/consent to take part based on that information.

Quantitative data consists of numbers or categories that can be mathematically quantified (for example, the number of helpers, the speed of help in seconds). It is objective and allows for direct comparison between conditions.

1 mark: Stating that it is numerical information, or data in the form of numbers/counts.
1 mark: Explaining a feature or purpose of quantitative data (e.g., it can be statistically analysed, measured, compared, or is highly objective).

Anthropomorphism occurs when a researcher interprets an animal's behavior using human mental concepts (for example, saying a monkey is 'jealous' or 'embarrassed'). To maintain scientific objectivity, researchers must describe behaviour in purely objective, observable terms rather than projecting human-like feelings onto them.

1 mark: Stating that it is the attribution of human characteristics, emotions, thoughts, or intentions.
1 mark: Identifying that these human qualities are wrongly or subjectively assigned to non-human animals (or objects).

To operationalise the independent variable (IV), Dr. Aris needs to define the two conditions clearly. Condition 1: A continuous background white noise (soft hum) played through a speaker at a standardized level, such as \( 45 \text{ decibels} \), throughout the REM period. Condition 2: Silence (no white noise hum played, control condition). To operationalise the dependent variable (DV) of dream vividness, Dr. Aris can use a structured self-report scale. Upon waking the participants during REM sleep, he can ask them to rate the vividness of their dream on a Likert scale from \( 1 \) (very vague/fragmented) to \( 5 \) (highly vivid, rich in visual and sensory details). Alternatively, he can measure the number of descriptive adjectives used in their verbal dream report.

Award up to 4.5 marks total: [1] Operationalisation of the IV (up to 2 marks): 1 mark for identifying the two levels of the IV (white noise vs no noise); 1 mark for specific operational details (e.g., standardizing the volume at \( 45 \text{ decibels} \), playing it during REM sleep). [2] Operationalisation of the DV (up to 2.5 marks): 1 mark for identifying a measurement of dream vividness; 1 mark for describing a specific scale or scoring method (e.g., \( 1 \text{ to } 5 \) self-report Likert scale); 0.5 marks for details of how/when it is collected (e.g., immediately upon awakening from REM sleep via a microphone).

For quantitative data, the psychologist can implement a standardized distress scale, similar to the Feelings Thermometer used by Saavedra and Silverman. The child would rate their fear or disgust on a scale of \( 0 \text{ to } 8 \) when exposed to balloons at different distances. This provides numerical data that can be compared over time to track improvement. For qualitative data, the psychologist can conduct brief semi-structured interviews after each therapy session, asking open-ended questions about what the child was thinking or feeling when touching a balloon. They can record the child's exact quotes and descriptions of their thoughts (e.g., 'I thought it would pop and hurt my ears') to understand the cognitive changes occurring during therapy.

Award up to 4.5 marks total: [1] Quantitative method (up to 2 marks): 1 mark for identifying a quantitative measure (e.g., rating scale, heart rate); 1 mark for describing how it applies to the balloon phobia scenario (e.g., rating distress from \( 0 \text{ to } 8 \) when exposed to a balloon). [2] Qualitative method (up to 2.5 marks): 1 mark for identifying a qualitative measure (e.g., open-ended interviews, observations of behavior); 1 mark for describing how it applies to the balloon phobia scenario (e.g., asking open questions about their thoughts of popping); 0.5 marks for explaining how this data helps assess therapy progress (e.g., tracking cognitive shift from fear to coping thoughts).

To implement a matched pairs design, Dr. Lin must first identify a participant variable relevant to the study, such as baseline attention capacity or memory span. He would administer a standardized pre-test, such as a digit-span task or a short focus test, to all participants. He would then rank participants based on their scores. The two participants with the closest scores would form a pair, the next two would form another, and so on. For each pair, Dr. Lin would use a random method (like a coin toss) to assign one participant to the 'clay kneading' group and the other to the control (sitting still) group. This controls for individual differences in baseline attention, ensuring any difference in performance during the boring lecture is due to the clay kneading rather than pre-existing abilities.

Award up to 4.5 marks total: [1] Identifying the relevant participant variable (up to 1.5 marks): 1 mark for choosing an appropriate variable to match (e.g., baseline attention span, memory capacity); 0.5 marks for explaining why it affects this specific study. [2] Explaining the matching process (up to 2 marks): 1 mark for describing how participants are pre-tested and ranked; 1 mark for explaining how pairs are formed from matching scores. [3] Group assignment (up to 1 mark): 1 mark for explaining random allocation within each pair to the two conditions (clay kneading vs control).

To ensure high inter-rater reliability, the psychologists should follow a systematic process. First, they must develop a highly specific and objective coding scheme. The behavioral categories must be operationalized clearly, leaving no room for subjective interpretation (e.g., 'initiating conversation' is defined as speaking at least one sentence to another person, rather than just standing near them). Second, the observers must undergo a training phase where they practice using the coding scheme on pre-recorded video tapes of social interactions in similar settings. Third, they should run a pilot observation where two observers independently code the same live behaviors of patients. Finally, they should calculate a statistical correlation (such as Cohen's Kappa) between their recorded scores. If the correlation is high (\( 0.80 \) or above), high inter-rater reliability is established. If it is low, they must revise the definitions and retrain.

Award up to 4.5 marks total: [1] Designing the coding scheme (up to 1.5 marks): 1 mark for proposing clear, operationalised, and mutually exclusive behavioral categories; 0.5 marks for a specific example relevant to schizophrenia (e.g., defining social withdrawal vs active conversation). [2] Training phase (up to 1 mark): 1 mark for explaining how observers practice together (e.g., using video recordings) to align their scoring. [3] Testing and mathematical agreement (up to 2 marks): 1 mark for describing a pilot session where observers score independently; 1 mark for explaining the calculation of a correlation coefficient (e.g., Kappa) and the threshold for high reliability (e.g., \( 0.80 \) or above).

Part (a): - IV: Doodling condition (shading pre-printed shapes on a page) vs. Control condition (listening on lined paper without instructions to doodle). - DV: Concentration measured by a surprise 15-question recall test based on details of a 15-minute standard history lecture. - Setting: Two separate quiet classrooms in a high school. - Sample: 40 students aged 16-17, recruited through opportunity sampling and randomly allocated to conditions. - Controls: Same recorded voice lecture, same volume, same temperature, same instructions. - Ethics: Parental informed consent, debriefing after the test, and confidentiality of individual scores. Part (b): - Limitation: Participant variables such as individual differences in baseline memory or interest in history may confound results. - Solution: Conduct a matched-pairs design where participants are matched on their baseline academic grades or memory performance before being allocated to the conditions.

Part (a) [10 marks]: - IV and DV operationalisation: 3 marks. - Setting and sample: 3 marks. - Controls: 2 marks. - Ethics: 2 marks. Level 4 (9-10 marks): Detailed, coherent, and highly replicable field experiment. Level 3 (6-8 marks): Good design with minor gaps in details. Level 2 (3-5 marks): Lacks detail or contains significant omissions. Level 1 (1-2 marks): Very basic attempt. Part (b) [4 marks]: - 1 mark for identifying a limitation (e.g., participant variables, distraction from doodling task). - 1 mark for explaining how it affects validity in this study. - 1 mark for suggesting a resolution (e.g., matching participants, pilot testing). - 1 mark for explaining how it works.

Part (a): - Type: Covert, non-participant observation. The researcher acts as a waiting patient to avoid demand characteristics. - Behavioral categories: Shifting seat (moving position), sighing (audible deep breath), checking phone (looking at screen), nail-biting (fingers to mouth). Recorded using a behavioral checklist. - Sampling: Time sampling. Each participant observed for 10 seconds every minute over a 10-minute period. - Reliability and Validity: Inter-rater reliability using two independent observers, calculating a correlation coefficient. Covert nature ensures ecological validity by eliminating the Hawthorne effect. Part (b): - Ethical issue: Covert observation in a clinical waiting room violates privacy and lacks informed consent. Participants may feel uncomfortable knowing their distressed behaviors were recorded. - Resolution: Obtain retrospective consent by debriefing participants as they leave the room, explaining the study, and obtaining permission to use their data. Destroy any data if consent is refused.

Part (a) [10 marks]: - Type of observation: 2 marks. - Behavioral categories and recording: 3 marks. - Sampling method: 3 marks. - Reliability and validity: 2 marks. Level 4 (9-10 marks): Thorough, appropriate, and structured naturalistic observation. Level 3 (6-8 marks): Clear design with minor gaps in operationalisation. Level 2 (3-5 marks): Weak design with major omissions. Level 1 (1-2 marks): Inappropriate design or very basic attempt. Part (b) [4 marks]: - 1 mark for identifying an ethical issue (e.g., privacy, consent). - 1 mark for explaining its impact in this study. - 1 mark for proposing a resolution (e.g., retrospective consent). - 1 mark for explaining how it resolves the issue.

The biomedical explanation of OCD focuses on abnormalities in brain structure, specifically within the 'worry circuit' (cortico-basal ganglia-thalamo-cortical loop). Under normal conditions, the orbitofrontal cortex (OFC) detects a stimulus and sends warning signals to the thalamus. The caudate nucleus (part of the basal ganglia) acts as a filter, deciding which signals are important enough to pass on. In individuals with OCD, the caudate nucleus is thought to be damaged or dysfunctional, meaning it fails to filter out minor or irrelevant worry signals. As a result, the thalamus becomes hyperactive and constantly transmits worry signals back to the OFC, creating a continuous loop of intrusive, obsessive thoughts and subsequent compulsive behaviours to alleviate the anxiety.

4 marks: A clear, accurate and detailed outline showing a thorough understanding of the brain structures and their functional loop in OCD. 3 marks: A mostly accurate outline describing the brain structures and how they function, but missing some detail or clarity on the loop mechanism. 2 marks: A basic outline identifying some brain structures (e.g., caudate nucleus, OFC) with limited explanation of their connection to OCD symptoms. 1 mark: A vague or brief answer that merely names a relevant brain structure (e.g., basal ganglia) without further explanation.

Locke and Latham's (1990) goal-setting theory proposes that specific and difficult goals lead to higher task performance than vague, non-specific goals (such as 'do your best') or no goals at all. The theory outlines five key principles necessary for goals to motivate employees: 1. Clarity: goals must be clear, specific, and measurable. 2. Challenge: goals should be difficult but achievable, as harder goals require more effort and increase satisfaction upon completion. 3. Commitment: employees must buy into the goal and feel personally invested. 4. Feedback: regular updates and praise help employees track their progress and adjust their strategies. 5. Task complexity: highly complex goals must be broken down into smaller, manageable sub-goals to avoid overwhelming the worker.

4 marks: A detailed and accurate outline of the theory, clearly stating the main premise (specific/challenging goals) and explaining at least three of the five key principles in detail. 3 marks: An accurate outline explaining the main premise and at least two principles, or mentioning several principles with limited detail. 2 marks: A basic outline of the theory that mentions the importance of setting challenging/specific goals and lists some principles without detailed explanation. 1 mark: A minimal response showing vague awareness of goal-setting (e.g., 'goals motivate workers if they are hard').

Strength:
- Identification: The study gathered rich, detailed longitudinal data.
- Application to study: Glover followed a 56-year-old female patient with a 14-year history of shoplifting, collecting detailed qualitative reports about her urges and using a 19-month follow-up to monitor her progress.
- Why it is a strength: This allows for an in-depth understanding of the cognitive process behind covert sensitisation and provides strong evidence for the long-term effectiveness of the therapy.

Weakness:
- Identification: The study has very low generalisability.
- Application to study: Because it is a case study of a single female patient suffering specifically from kleptomania, the results may not represent how others would respond.
- Why it is a weakness: We cannot assume that covert sensitisation would work as effectively for men, younger demographics, or individuals with different impulse control disorders (like pyromania or gambling disorder).

For each strength/weakness (out of 3 marks):
- 1 mark: Clearly identifies an appropriate strength/weakness.
- 1 mark: Applies the strength/weakness directly to Glover (2011) using accurate study details.
- 1 mark: Explains the psychological consequence or benefit/drawback of this feature (e.g. why it helps/hinders validity, reliability, or application).

Strength:
- Identification: High ecological validity and realism.
- Application to study: Janis investigated actual, real-world historical decisions made by key political committees, such as the defense of Pearl Harbor and the Cuban Missile Crisis.
- Why it is a strength: This ensures that the symptoms and outcomes of groupthink observed are genuine and reflective of real organizational dynamics under high pressure, which cannot be artificially replicated in lab experiments.

Weakness:
- Identification: Retrospective researcher bias and lack of control.
- Application to study: Janis relied on qualitative, historical archives, memoirs, and reports compiled after the decisions had already succeeded or failed.
- Why it is a weakness: This makes the research subjective, as Janis could selectively analyze documents to support his theory of groupthink (confirmation bias), and there is no way to control for post-hoc rationalisation by the decision-makers in their memoirs.

For each strength/weakness (out of 3 marks):
- 1 mark: Clearly identifies an appropriate strength/weakness of historical case studies/qualitative analysis.
- 1 mark: Applies the point directly to Janis's (1972) work on groupthink.
- 1 mark: Explains the methodological consequence (e.g., how it impacts validity, reliability, or objectivity).

A high-quality response will demonstrate accurate knowledge of biological explanations (genetic, biochemical/dopamine hypothesis, and brain abnormalities) and cognitive explanations (e.g., Frith's model of metarepresentation and supervisory attentional system failure). Evaluation should focus on the named issue (reductionism vs. holism): biological explanations are highly reductionist as they isolate chemical imbalances (dopamine) or genetic risk factors, ignoring social factors. Cognitive explanations are also somewhat reductionist as they reduce the disorder to information processing deficits, but they can be integrated more easily with situational elements. Other evaluation points include: nature versus nurture (biological supports nature; cognitive supports an interaction where biological predispositions are triggered or processed incorrectly), determinism versus free will (biological determinism vs. cognitive control), and practical applications (such as drug therapies vs. Cognitive Behavioral Therapy).

Level 4 (16-20 marks): Outstands in both knowledge and evaluation. Detailed and accurate description of both biological and cognitive explanations of schizophrenia. Evaluation is robust, balanced, and contains a well-argued, explicit discussion of reductionism versus holism. Demonstrates excellent structure and psychology-specific terminology.
Level 3 (11-15 marks): Good knowledge and understanding. Evaluation is mostly balanced, and the discussion of reductionism is present but may lack depth or detail.
Level 2 (6-10 marks): Limited or superficial knowledge. Evaluation is basic, one-sided, or lacks a coherent discussion of reductionism.
Level 1 (1-5 marks): Answer is purely descriptive with little to no relevant evaluation, or is highly confused and disorganized.

Candidates should outline cognitive theories such as Vroom's VIE theory (Valence, Instrumentality, Expectancy) and Locke & Latham's goal-setting theory (which outlines the importance of specific, challenging goals and feedback). The evaluation must directly address the individual versus situational debate: cognitive theories rely heavily on individual perception (e.g., how much an individual values a reward, or their personal self-efficacy), representing an individualist view. However, they also incorporate situational factors, such as the clarity of organizational goals, difficulty of tasks set by managers, and the concrete rewards provided by the environment. Other evaluative points should include: practical applications for management (e.g., how to design bonus schemes or performance reviews), methodological issues (e.g., the reliance on self-report questionnaires which may suffer from social desirability bias), and the deterministic nature of expectancy calculations.

Level 4 (16-20 marks): Explains cognitive theories of motivation with high accuracy. The evaluation is detailed, balanced, and includes a sophisticated discussion of the individual versus situational debate. Consistent use of relevant psychological terminology.
Level 3 (11-15 marks): Good explanation of the theories. The evaluation is balanced, and the individual/situational debate is addressed, though it may lack absolute depth or thorough integration.
Level 2 (6-10 marks): Basic description of the theories with limited evaluation. The discussion of individual versus situational factors is weak or missing.
Level 1 (1-5 marks): Little to no relevant knowledge or evaluation. Mostly descriptive, fragmented, or highly superficial.

(a)
Based on the stimulus, the two clinical characteristics of kleptomania are:
1. Experiencing a mounting tension/build-up of arousal prior to committing the theft.
2. Stealing items that are not needed for personal use or monetary value, followed by a feeling of gratification/pleasure/relief after the act.

(b)
Covert sensitization is an in-imagination behaviour therapy that pairs the unwanted impulse with an unpleasant stimulus:
- Dr. Lin would first teach Marcus relaxation techniques to prepare him for visualization.
- Marcus would be guided to imagine a sequence of events leading up to a theft in vivid detail (e.g., entering a store, seeing an object, reaching out to take it).
- At the peak of the urge (just as Marcus is about to take the item), Dr. Lin instructs him to imagine a highly aversive, disgusting, or shameful consequence (e.g., vomiting all over himself, being publicly arrested, or being humiliated in front of his family).
- The unpleasant mental image is held vividly to condition an aversion to the act of stealing.
- Finally, Marcus is asked to visualize putting the item down, walking away from the store, and feeling a massive sense of relief and clean comfort.

(c)
An alternative treatment is imaginal desensitization (or biochemical treatments):
- **Imaginal Desensitization:** This involves teaching the client progressive muscle relaxation techniques. Once relaxed, the client is asked to visualize a triggering scenario (e.g., wanting to gamble or steal) and mentally go through the situation step-by-step while remaining completely relaxed, eventually visualizing themselves walking away without acting on the impulse. This prevents the physiological arousal associated with the impulsive behavior.
- **Biochemical Treatments:** Medications such as opiate antagonists (e.g., naltrexone) block the release of dopamine in the brain's reward pathway, thereby reducing the 'rush' or pleasure associated with the impulsive behaviour. Alternatively, SSRIs can be prescribed to address underlying obsessive-compulsive impulses or mood issues.

(d)
**Strengths:**
- **No physical side effects:** Unlike drug therapies (biochemical treatments), covert sensitization does not carry risks of physical dependency or physiological side effects.
- **Empowerment and self-control:** It equips the patient with a cognitive strategy they can independently use in real-world scenarios whenever they feel a trigger.
- **Ethical advantage:** Unlike classic aversion therapy, which uses real physical shocks or emetics, the aversive stimuli are entirely covert (imagined), making it a more humane intervention.

**Weaknesses:**
- **Relies on cognitive capability:** The therapy's success depends entirely on the patient's ability to generate vivid, detailed mental images of both the urge and the aversive consequence.
- **High attrition rates:** Because patients must repeatedly imagine highly unpleasant and distressing scenarios (such as public humiliation or vomiting), they may find the process too unpleasant and drop out of therapy.
- **Symptom substitution:** It suppresses the immediate behavioral urge but does not necessarily resolve the underlying psychological causes or trauma that triggered the kleptomania.

**(a)**
- 1 mark for each characteristic clearly identified from the stimulus, up to a maximum of 2 marks.
- Acceptable points: mounting tension before stealing; stealing items that are not needed; feeling gratification after the act.

**(b)**
- 1 mark for a basic description of pairing stealing with an unpleasant image.
- 2–3 marks for a detailed description containing core elements (progressive visualization of the urge, introduction of the aversive/disgusting event, and the final relief stage).
- 4 marks for a comprehensive, highly accurate description of how Dr. Lin would implement the steps with Marcus.

**(c)**
- 1 mark for naming an appropriate alternative therapy (e.g., biochemical therapy / imaginal desensitization).
- 2 marks for a basic explanation of how this alternative therapy works.
- 3–4 marks for a detailed outline showing clear psychological understanding of the mechanisms (e.g., blocking dopamine receptors for naltrexone, or systematically pairing muscle relaxation with the mental urge to walk away in imaginal desensitization).

**(d)**
- 1–2 marks for identifying and briefly explaining general strengths/weaknesses.
- 3–4 marks for a balanced discussion with at least one clear strength and one clear weakness of covert sensitization specifically.
- 5 marks for a well-structured, insightful evaluation showing sophisticated psychological reasoning and appropriate terminology.

(a)
In Hackman and Oldham's Job Characteristics Model, the Motivating Potential Score (MPS) is a quantitative index that measures the overall potential of a job to foster high internal work motivation.
- It is calculated using the five core job dimensions with the following formula: \(MPS = \frac{\text{Skill Variety} + \text{Task Identity} + \text{Task Significance}}{3} \times \text{Autonomy} \times \text{Feedback}\).
- The formula shows that Autonomy and Feedback are critical multipliers; if either of these is zero, the overall motivating potential of the job becomes zero.

(b)
Candidates can describe any two of the following dimensions (2 marks each):
1. **Skill Variety:** The degree to which a job requires a range of different activities, enabling the employee to use various talents and skills.
2. **Task Identity:** The degree to which a job requires completion of a whole and identifiable piece of work (doing a job from beginning to end with a visible outcome).
3. **Task Significance:** The degree to which the job has a substantial, perceivable impact on the lives or work of other people (either inside or outside the organization).
4. **Autonomy:** The degree of freedom, independence, and discretion given to the employee to schedule their work and determine the procedures to carry it out.
5. **Feedback:** The degree to which the work activities provide direct and clear information to the employee about the effectiveness of their performance.

(c)
Job enrichment involves the vertical expansion of jobs, giving employees more responsibility, control, and feedback. The HR manager can apply this to software developers by:
- **Increasing Autonomy:** Allowing developers to schedule their own work hours, choose their programming languages/tools, or make final decisions on architectural design without needing manager approval.
- **Enhancing Task Identity:** Shifting from a system where developers only code isolated modules to one where a single developer is responsible for an entire application from client requirements analysis to final deployment.
- **Establishing Feedback Loops:** Setting up direct channels for developers to interact with the end-users of their software to see the impact of their work and receive direct feedback on how to improve it (also boosting Task Significance).

(d)
Not all employees respond the same way to job redesign; the JCM identifies key individual moderator variables:
- **Growth Need Strength (GNS):** This is the degree to which an individual desires personal growth, self-actualization, and development. Employees with high GNS will thrive in enriched jobs with high MPS. Conversely, employees with low GNS may find the increased responsibility and variety stressful or anxiety-inducing, and may prefer simple, routine tasks.
- **Knowledge and Skills:** If employees lack the necessary competence or training to handle the enriched job's new demands, they will experience frustration, low self-efficacy, and stress rather than high motivation.
- **Context Satisfaction:** If employees are highly dissatisfied with their pay, job security, co-worker relationships, or managers, they are unlikely to respond positively to job enrichment attempts, as basic hygiene factors must be met first.

**(a)**
- 1 mark for explaining that MPS is a predictive quantitative score/index used to measure job motivation.
- 1 mark for outlining how it is calculated (e.g., showing the formula, or explaining that autonomy and feedback act as multipliers on the other three dimensions).

**(b)**
- For each core dimension (maximum of 2 dimensions):
- 1 mark for naming and basic definition.
- 1 mark for elaboration/description of what it entails.

**(c)**
- 1–2 marks for explaining the concept of job enrichment (vertical job expansion, increasing responsibility and autonomy).
- 3–4 marks for linking job enrichment explicitly to the JCM dimensions in the context of the software development firm (e.g., developers getting to manage client relationships, complete entire software features, or schedule their tasks).

**(d)**
- 1–2 marks for identifying at least one individual difference (such as Growth Need Strength).
- 3–4 marks for explaining how different levels of these variables (high vs. low GNS, high vs. low skills, or context satisfaction) lead to different motivation outcomes in redesigned jobs.
- 5 marks for a sophisticated, balanced discussion using precise psychological terms (GNS, moderators, context satisfaction).

### Part (a) Proposed Design of the Study

* **Research Design and Sample:** This study will use a correlational research design via a self-report questionnaire. The sample will consist of 60 software developers (45 male, 15 female, aged 22–45) recruited via opportunity sampling from a large multinational software engineering firm that has recently implemented a performance-related pay (PRP) program.
* **Administration & Ethics:** The questionnaire will be created online using a secure platform and distributed via company email. An introductory page will explain the study's purpose, guarantee absolute anonymity (to reduce social desirability bias), obtain informed consent, and explicitly state that participants can withdraw at any point.
* **The Questionnaire Structure:**
* **Section 1: Demographics & PRP perception.** Questions will assess how long they have worked under the PRP scheme and their perception of it (e.g., "What percentage of your monthly income is dependent on performance milestones?").
* **Section 2: Intrinsic Motivation (Quantitative).** Five Likert-scale questions will measure intrinsic motivation, adapted from the Work Extrinsic and Intrinsic Motivation Scale (WEIMS). Participants rate statements on a scale of 1 (strongly disagree) to 5 (strongly agree). Statements will include:
1. "I write code because I derive personal satisfaction from solving complex logic problems."
2. "I feel a sense of personal growth when mastering a new programming language."
3. "Even if I were not paid, I would still enjoy working on software projects."
These scores will be summed to create an 'Intrinsic Motivation Index' ranging from 5 to 25.
* **Section 3: Qualitative Experience.** To gain deeper insight, one open-ended question will be included: "Please describe in your own words how the introduction of the performance-related pay scheme has affected your day-to-day enjoyment of programming."
* **Data Analysis:** Quantitative scores will be analysed using a Spearman's rho correlation test to see if there is a negative correlation between the perceived strength of the extrinsic reward (PRP) and intrinsic motivation scores. Qualitative comments will undergo thematic analysis to identify common feelings (e.g., pressure, loss of autonomy).

### Part (b) Explanation of Decisions

* **Methodological Decisions:**
* **Anonymity & Distribution:** Software developers might fear that admitting low motivation or dislike of the new PRP scheme could lead to termination or negative performance reviews. Administering an anonymous online survey ensures ecological validity and reduces social desirability/evaluation apprehension.
* **Mixed-methods Approach:** Combining quantitative Likert-scales with open-ended questions allows for triangulation. The quantitative scale provides numerical data that is easy to statistical analyze for correlation, while the qualitative question provides the depth needed to understand the underlying thoughts and feelings of the developers.
* **Sampling Strategy:** Opportunity sampling within a single large firm ensures that all participants are under the exact same organisational structure and PRP framework, minimising external confounding variables.

* **Psychological Decisions:**
* **Cognitive Evaluation Theory (Deci & Ryan):** This study is grounded in Cognitive Evaluation Theory, which states that when individuals are given extrinsic rewards (like PRP) for doing a task they already enjoy, their perceived locus of causality shifts from internal (doing it for joy) to external (doing it for money). This "overjustification effect" reduces intrinsic motivation.
* **Operationalisation of Intrinsic Motivation:** The questionnaire items directly target the core pillars of intrinsic motivation: autonomy, competence, and task enjoyment. Questions are phrased to isolate personal satisfaction from financial incentives, ensuring construct validity.

### Part (a) [10 marks]
* **9–10 marks:** The design is highly detailed, fully appropriate, and easily replicable. All key aspects of the questionnaire are addressed (sample, explicit examples of questions, Likert scale details, administration, data collection, and ethical safeguards).
* **7–8 marks:** The design is appropriate and has good detail. It might lack minor clarification in one area (e.g., sample size is vague or questionnaire questions are slightly underdeveloped).
* **5–6 marks:** The design is basic. It is recognisable as a questionnaire but lacks sufficient detail to replicate (e.g., no clear example questions, or lacks analytical details).
* **3–4 marks:** Major omissions in design. It may not clearly measure the intended variables, or may read like a generic research methods essay.
* **1–2 marks:** Extremely weak attempt with very little detail or structural relevance.

### Part (b) [8 marks]
* **7–8 marks:** Explicit and accurate justification of both methodological choices (e.g., why mixed questions, why anonymity, why opportunity sampling) and psychological theory (e.g., Cognitive Evaluation Theory, intrinsic vs. extrinsic dynamics). Ideas are well-structured and fully integrated with the design.
* **5–6 marks:** Good explanation of decisions, but may focus heavily on methodology while giving only a brief mention of the psychological theory, or vice versa.
* **3–4 marks:** Basic explanation of decisions. The links between the design choices and psychology/methodology are weak or superficial.
* **1–2 marks:** Very limited or purely descriptive response. Little to no justification for choices made.

Explanations of impulse control disorders (ICDs), such as kleptomania, pyromania, and gambling disorder, can be understood through biochemical (dopamine), behavioral (operant conditioning), and cognitive (Feeling-State theory) perspectives.

One major area of evaluation is the individual versus situational debate. Individual explanations argue that the onset and maintenance of ICDs stem from factors internal to the person. For instance, the biochemical explanation points to individual differences in neurotransmitter systems, suggesting that individuals with ICDs have a dysfunctional dopamine reward pathway, leading them to seek out risky behaviors to experience a normal reward sensation. Similarly, Miller's Feeling-State theory is an individual-focused cognitive explanation, proposing that an individual's unique cognitive pairing of an intense positive emotion (e.g., feeling powerful) with a specific act (e.g., shoplifting) creates a persistent compulsion. In contrast, situational explanations suggest that environmental triggers and rewards maintain these behaviors. The behavioral explanation emphasizes operant conditioning, where external triggers—such as the sensory environment of a casino (flashing lights, sounds) or the immediate reward of obtaining a stolen item—reinforce the behavior. This perspective suggests that the behavior is heavily dependent on situational cues and rewards rather than purely internal drives.

Another critical point of evaluation is reductionism versus holism. The biochemical explanation is highly reductionist as it simplifies complex compulsive behaviors down to basic neurochemical imbalances (dopamine deficiency). While this reductionist view makes it easier to design targeted drug therapies (like opioid antagonists), it fails to address why an individual chooses a specific outlet (such as fire-setting over gambling) to satisfy their urge. Conversely, the Feeling-State theory is more holistic because it attempts to integrate physiological arousal, emotional states, and cognitive beliefs to explain the disorder.

In terms of usefulness and application, individual explanations are highly valuable for clinical interventions, such as using cognitive-behavioral therapy (CBT) to restructure cognitive feeling-states or using pharmacotherapy to regulate neurotransmitters. However, ignoring situational factors can limit treatment efficacy. For example, if a recovering gambler is continuously exposed to high-risk environments, situational cues may trigger a relapse regardless of biochemical or cognitive treatment. Therefore, a holistic, interactionist approach that accounts for both individual vulnerability and environmental situations is the most comprehensive way to explain and treat impulse control disorders.
