In Milgram's study on obedience, the sample consisted of 40 male participants aged between 20 and 50 years. They were recruited from the New Haven area and surrounding communities using a newspaper advertisement and direct mail. The sample represented a wide range of backgrounds and occupations, including laborers, blue-collar workers, white-collar workers, and professionals. They were paid $4.50 for their participation.

Award 1 mark per correct detail described, up to a maximum of 3 marks: 40 participants; All males; Aged 20 to 50 years; From New Haven (or surrounding area); Varied occupations/occupational backgrounds (such as postal clerks, teachers, engineers, and laborers); Recruited via newspaper advertisement/direct mail; Paid $4.50 (for showing up).

In the original version of the Eyes Test, participants chose between only two response options (opposites). In the revised version, Baron-Cohen et al. increased the number of response choices to four (one correct target word and three foil words). This modification was made to reduce the high likelihood of participants correctly guessing the answer by chance (which was 50% in the original version), thereby making the test a more sensitive and valid measure of social cognitive ability.

Award 1 mark for describing the original format (two choices/opposites). Award 1 mark for describing the revised format (four choices/one target and three foils). Award 1 mark for explaining the reason for the change (e.g., to reduce the chance of guessing / from 50% to 25% / to make it a more sensitive and valid measure of theory of mind).

In the computerized CID task, participants were asked to imagine themselves at the center of a circular screen. They were shown a drawing of an avatar (representing a friend, stranger, etc.) that would start at the edge of the circle and move towards the center from one of eight directions. Participants were instructed to press the spacebar to stop the approaching figure at the moment they began to feel uncomfortable with its proximity. The final distance was recorded as a percentage of the total radius of the circle.

Award 1 mark per correct point, up to a maximum of 3 marks: Participants imagined themselves at the center of a circle/screen; An avatar (representing a target person) approached them from the edge/from eight directions; Participants pressed a key (the spacebar) to stop the movement when they felt uncomfortable/too close; The distance was recorded as a percentage of the total possible distance/radius.

Before listening to the telephone message, participants in the doodling group were given a piece of paper with shapes (circles and squares) on it. They were instructed to shade in these shapes while listening to the tape. They were explicitly told that it did not matter how neatly or quickly they shaded the shapes, as it was just a task to relieve boredom. Additionally, they were instructed to listen to the tape and write down the names of the people who would be attending the party (while ignoring those who said they could not attend).

Award 1 mark per correct point, up to a maximum of 3 marks: To shade in the shapes (circles and squares) on the response sheet; Told that it did not matter how neatly or quickly they did this; Told it was just to relieve boredom; To write down the names of the people attending the party; To ignore the names of people who could not attend.

To ensure that child participants understood the line-up task and the option of rejecting a line-up when the target was absent, Pozzulo et al. conducted a practice trial using familiar cartoon characters (Dora the Explorer or Go, Diego, Go!). Children were first shown a target picture of one of these characters. They were then shown a practice line-up containing four cartoon characters, which was either target-present or target-absent. The researcher guided them to make an identification or point to the 'not there' box, confirming they understood that the cartoon character might not be in the line-up.

Award 1 mark per correct point, up to a maximum of 3 marks: Used familiar cartoon characters (e.g., Dora the Explorer / Go, Diego, Go!); Shown a target picture first, followed by a line-up of four characters; The line-up was target-present or target-absent; Taught/guided them how to select the target or use the 'not there' box (to show they understood the target might not be present).

In the observation room, the researchers recorded specific behaviors that directly copied the adult model's physical aggression. Three of these behaviors classified as 'imitative physical aggression' were: striking the Bobo doll with the mallet, sitting on the Bobo doll and punching it in the nose, and kicking the Bobo doll or tossing it in the air.

Award 1 mark for each correct behavior identified, up to a maximum of 3 marks: Striking the Bobo doll with a mallet; Sitting on the Bobo doll and punching it in the nose; Kicking the Bobo doll; Tossing the Bobo doll in the air.

Hassett et al. measured toy interaction using two primary quantitative measures: the duration of interaction (the total time in seconds spent interacting with a toy) and the frequency of interaction (the number of times a monkey initiated contact with a toy). Interaction was operationalized as physical contact with the toy, which included specific behaviors such as holding, touching, sniffing, chewing, carrying, or actively manipulating the toy. Crucially, passive contact such as sitting on the toy or using it to climb on was not counted as an interaction.

Award 1 mark per correct point, up to a maximum of 3 marks: Measured using the duration of interaction (time spent); Measured using the frequency of interaction (number of times); Defined interaction as physical contact (e.g., touching, holding, sniffing, carrying, chewing); Did not count passive contact (such as sitting on the toy or climbing on it).

To ensure high internal validity, several controls were implemented during the laboratory sessions: 1) Participants were instructed to avoid consuming caffeine and alcohol on the day of the experiment; 2) They slept in a quiet, dark room; 3) They were awakened by a loud, clear doorbell sound placed near the bed, which controlled for any variations in how they were woken up; and 4) They were required to speak immediately into a tape recorder to describe their dream before talking to the experimenter.

Award 1 mark for each control procedure described, up to a maximum of 3 marks: Participants had to avoid caffeine/alcohol on the day of the study; Participants slept in a quiet, dark room; All participants were awakened using a loud doorbell sound; Wakeups occurred immediately after a burst of eye movements (or after a set interval of REM/NREM); Participants spoke immediately into a tape recorder upon waking / did not communicate with the experimenter first; Electrodes were gathered into a single pony-tail/cord at the head to allow normal movement.

### Model Response

**1. Ecological Validity (Differences)**
- **Milgram (obedience):** This study has low ecological validity. It was conducted in a controlled laboratory setting at Yale University. The task itself—administering electric shocks to an innocent learner in a word-association game—is highly artificial and not an everyday occurrence. Although the experimental realism was high (participants believed the shocks were real), the environment and the task do not represent obedience in typical real-life scenarios.
- **Piliavin et al. (subway Samaritans):** This study has high ecological validity. It was a field experiment conducted in a real-world setting: a moving New York subway train (the Eighth Avenue Independent line). The participants (subway passengers) were in their natural environment, and the event of a passenger (the victim) collapsing is a realistic emergency situation that could occur in everyday life.

**2. Ethical Issues (Similarities and Differences)**
- **Similarities:**
- Both studies subjected participants to **psychological distress**. In Milgram's study, participants experienced extreme anxiety, sweating, trembling, and even seizures. In Piliavin et al.'s study, witnesses to the collapse experienced distress and anxiety, sometimes leading to coping mechanisms like moving away or talking to other passengers to justify not helping.
- Both studies involved **deception**. Milgram's participants believed they were randomly assigned roles and that they were administering real shocks. Piliavin's participants believed the collapsed victim was genuinely ill or drunk.
- **Differences:**
- **Informed Consent and Right to Withdraw:** Milgram's participants volunteered for a study on 'memory and learning' (though they did not consent to an obedience study). During the study, their right to withdraw was compromised by verbal prods (e.g., 'You have no other choice, you must go on'). However, they could physically leave. In contrast, Piliavin's participants had absolutely no informed consent (they were simply riding a train) and no practical right to withdraw, as they were trapped on a moving train for the 7.5-minute journey.
- **Debriefing:** Milgram provided a thorough debriefing at the end of the session, introducing the participant to the unharmed learner and offering psychiatric follow-ups. Piliavin et al. did not debrief the participants, meaning passengers left the train believing they had witnessed a real medical emergency or an intoxicated man collapsing.

### Marking Scheme (8 Marks)

**Level 4 (7–8 marks):**
- Explains both similarities and differences between the two studies clearly and in detail.
- Explicitly and accurately addresses both ecological validity and ethical issues.
- Demonstrates excellent knowledge and understanding of both core studies.
- Well-structured and uses appropriate psychological terminology.

**Level 3 (5–6 marks):**
- Compares both studies in relation to both ecological validity and ethical issues, but the explanation of one aspect may be slightly weaker or lack detail.
- Shows good knowledge and understanding of both core studies.
- Structure is mostly clear with good use of terminology.

**Level 2 (3–4 marks):**
- Only addresses one aspect (either ecological validity or ethics) in detail across both studies, OR covers both aspects but only for one study in detail.
- Demonstrates basic knowledge of the studies with limited comparison.
- Mostly descriptive with limited analytical comparison.

**Level 1 (1–2 marks):**
- Offers a brief, highly generalized, or inaccurate description of one or both studies.
- No effective comparison is made.
- Minimal understanding of ecological validity or ethics shown.

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

Strength 1 (Objective measurements): The study utilized Magnetic Resonance Imaging (MRI) scans and voxel-based morphometry (VBM) to measure grey matter concentration. This provided highly objective, quantitative data about biological changes in brain structures like the hippocampus and amygdala. Since these measurements are physiological, they are free from participant bias, demand characteristics, or researcher subjectivity, increasing the scientific validity of the findings. Strength 2 (Standardization): The Mindfulness-Based Stress Reduction (MBSR) program followed a highly standardized 8-week course structure, and the MRI scanning protocols were identical for all participants. This high control allowed the researchers to confidently isolate the effects of the mindfulness intervention on brain structure, making the study highly replicable. Weakness 1 (Self-report reliance): To measure home practice, participants self-reported their daily practice times. This self-report method is prone to social desirability bias, where participants might overestimate their practice hours to appear compliant, or memory inaccuracies, potentially undermining the reliability of the practice-to-brain-change correlation. Weakness 2 (Sample generalizability): The final sample was small (16 in the mindfulness group and 17 in the control group) and self-selected, consisting of healthy, motivated individuals seeking stress reduction. This limits the generalizability of the findings to a wider, more diverse clinical or demographic population who might respond differently to mindfulness training.

Level 4 (8-10 marks): Evaluation is comprehensive, discussing two strengths (including the required focus on objective measurements) and two weaknesses. Points are explicitly linked to the Hölzel et al. study with accurate detail and high-quality psychological understanding. Level 3 (5-7 marks): Evaluation is good but may lack balance or specific detail from the study. Discusses strengths and weaknesses, including objective measurements. If the required element is omitted, maximum 6 marks. Level 2 (3-4 marks): Basic evaluation. Shows limited understanding of the study's strengths and weaknesses. Points are mostly descriptive. Level 1 (1-2 marks): Very limited or confused response. Simple descriptive points about the study are present but little to no evaluation. Level 0 (0 marks): No response worthy of credit.

Strength (1 mark): Using a computerized avatar allows for extreme standardization (e.g., maintaining identical facial expressions, clothing, and distance increments across all trials), eliminating potential extraneous variables from a human confederate.

Weakness (1 mark): It lacks ecological validity or mundane realism. Dragging a slider on a screen is not a natural way to measure or experience personal space boundaries.

Contextualisation (1 mark): This is achieved by linking the evaluation directly to the digital avatar, the 0-100 cm slider interface, or physical personal space boundaries.

1 mark for explaining a clear methodological strength (e.g., control over extraneous variables, high standardization).
1 mark for explaining a clear methodological weakness (e.g., lack of ecological validity, low mundane realism).
1 mark for applying/linking either the strength or the weakness to the specific context of this simulation study (e.g., using a slider, digital avatar, or personal space).

Breach 1: Protection from psychological harm (1 mark). The stress and intense frustration generated by forcing participants to copy endless phone numbers under pressure can cause emotional distress.

Breach 2: Right to withdraw (1 mark). Standardized verbal prods (e.g., 'You have no other choice, you must go on') make it highly difficult for the participant to exercise their right to leave the study.

Contextualisation (1 mark): The response is explicitly linked to the scenario details, such as the tedious task of copying telephone numbers or the active use of Milgram-style verbal prods.

1 mark for identifying and explaining the first ethical breach (e.g., protection from harm).
1 mark for identifying and explaining the second ethical breach (e.g., right to withdraw).
1 mark for contextualising the breaches to the experimental scenario (e.g., referencing copying telephone numbers or the verbal prods).

Interpretation (1 mark): The humorous advert's lower standard deviation (1.1) shows that participants' recall scores were highly consistent and close to the mean, whereas the serious advert's higher standard deviation (2.4) shows that memory performance varied widely among participants.

Comparison of Measures (1 mark): Standard deviation is a better measure of dispersion than range because it calculates how much all scores deviate from the mean, making it less sensitive to extreme anomalies than the range.

Contextualisation (1 mark): Directly references the specific values (1.1 and 2.4), the types of adverts, or the recall scores.

1 mark for a correct interpretation of the standard deviation values in this scenario (identifying which group is more consistent/spread out).
1 mark for explaining why standard deviation is statistically superior to the range (accounting for all data points/reducing outlier distortion).
1 mark for linking the response to the recall scores or advert conditions.

Direction (1 mark): The positive sign (\(+\)) indicates a positive relationship; as performance on the Eyes Test increases, self-reported empathy scores also increase.

Significance (1 mark): The value of \(p < 0.01\) shows that the relationship is highly significant, meaning there is less than a 1% probability that this correlation occurred by random chance.

Contextualisation/Conclusion (1 mark): Links both terms clearly to the specific variables: the Eyes Test (theory of mind) and empathy scores.

1 mark for explaining the positive direction of the correlation in context.
1 mark for explaining the meaning of the significance level (\(p < 0.01\)).
1 mark for explicit link to both variables (the Eyes Test and empathy questionnaire).

Control of participant variables (1 mark): It ensures that baseline symptom levels are relatively equal across the comparison groups, preventing baseline differences from acting as an extraneous variable.

Enhancing internal validity (1 mark): It ensures that any difference in improvement observed after 6 weeks is more likely due to the CBT program itself, rather than one group having an unfair advantage of milder symptoms from the start.

Contextualisation (1 mark): Specifically applies this logic to schizophrenia symptoms, symptom severity, or the therapy timeline.

1 mark for identifying that it controls for participant variables / individual differences.
1 mark for explaining how this control prevents a confounding variable from distorting the results (improving internal validity).
1 mark for linking the explanation directly to schizophrenia symptom severity or CBT therapy.

Operationalising the IV (1 mark): Fast tempo is specified (e.g., songs over 120 BPM) and slow tempo is specified (e.g., songs under 70 BPM).

Operationalising the DV (1 mark): Explaining exactly how spending is measured (e.g., the total dollar amount recorded on the register receipt at checkout).

Context/Application (1 mark): Ensuring both variables are described in terms that are concrete, measurable, and tailored directly to the supermarket store environment.

1 mark for operationalising the IV with a measurable, clear standard (e.g., specific BPM values for fast and slow tempo).
1 mark for operationalising the DV with a clear measurement method (e.g., total spent in dollars/currency on the store receipt).
1 mark for applying both to the context of a supermarket/shopping environment.

Advantage (1 mark): It allows for flexibility and follow-up prompts. This is useful when discussing sensitive, complex experiences like OCD compulsions and ERP therapy, as patients can elaborate in their own words.

Disadvantage (1 mark): Reduced reliability and standardization. Because the questions vary based on the participant's answers, it is harder to replicate the study or compare the therapy outcomes directly.

Context (1 mark): Linked directly to OCD symptoms, exposure therapy (ERP), or patient anxiety experiences.

1 mark for explaining a valid advantage of a semi-structured interview (e.g., flexibility, depth, qualitative rich data).
1 mark for explaining a valid disadvantage (e.g., difficult to replicate, harder to compare/analyze, interviewer bias).
1 mark for contextualising the response to OCD symptoms or ERP therapy experiences.

Experimental Design (1 mark): Independent measures design (as different participants are allocated to either Condition A or Condition B).

Random Allocation Method (1 mark): Describe how random allocation is performed (e.g., using a computer random number generator or drawing group names out of a hat).

Control of Variables (1 mark): Explain how this controls for participant variables (e.g., it ensures that pre-existing traits, like how much coffee they usually drink or their income, are spread evenly across the conditions so they do not confound the DV).

1 mark for correctly identifying the design as independent measures.
1 mark for explaining a practical method of random allocation.
1 mark for explaining how random allocation controls for participant variables/individual differences (e.g., coffee habits or income) in this scenario.

An effective design could be:

1. Operationalisation of Variables:
- Variable 1 (Desk sitting time): Measured objectively using a pressure-sensitive seat pad sensor placed on each participant's office chair. The sensor automatically logs the total cumulative minutes spent sitting at the desk between 09:00 and 17:00 (excluding a mandatory 1-hour lunch break when everyone is away from their desks).
- Variable 2 (Physical fatigue): Measured using a self-report Likert scale questionnaire administered at exactly 17:05 daily. Participants rate their fatigue on a scale of 1 (not at all fatigued; feeling highly energetic) to 10 (extremely fatigued; physical exhaustion).

2. Sample and Sampling Method:
- A sample of 40 administrative office workers (20 males, 20 females, aged 25-50) will be recruited using opportunity sampling from a large marketing firm in London. This sample is suitable as they spend most of their workday at desks.

3. Procedure:
- Participants are fully briefed and provide written informed consent.
- Over a 5-day working week (Monday to Friday), the seat sensors continuously record sitting duration.
- At 17:05 each day, a automated email link is sent to participants to complete the 1-to-10 fatigue scale.
- At the end of the week, a mean daily sitting time (in minutes) and a mean daily fatigue rating are calculated for each participant.
- The data is plotted on a scatter graph, and a Spearman's correlation coefficient is calculated to determine the strength and direction of the relationship.

4. Ethical Considerations and Controls:
- Confidentiality: Participants are assigned numerical codes (e.g., Participant 1, Participant 2) so their names are not associated with their sitting time or fatigue ratings.
- Standardisation: The daily questionnaire is sent at the exact same time (17:05) to control for diurnal fatigue fluctuations.

Marking bands:

Level 3 (8-10 marks):
- The design is highly detailed, practical, and fully appropriate for a correlational study.
- Both variables are clearly operationalised (e.g., precise measurement of sitting time and fatigue).
- The sample, sampling method, and procedure are logical and clearly explained.
- Key controls and relevant ethical issues are addressed.
- Consistent use of correct psychological research methods terminology.

Level 2 (5-7 marks):
- The design is practical and appropriate, but lacks some detail.
- One or both variables are operationalised, but one may lack precision.
- The procedure is outlined but contains minor omissions or ambiguities.
- Some psychological terminology is used correctly.

Level 1 (1-4 marks):
- The design is basic and may have major flaws (e.g., describing an experiment rather than a correlation).
- Variables are poorly operationalised or not operationalised at all.
- Key details regarding sample, procedure, or ethics are missing.

Level 0 (0 marks):
- No response, or response is completely irrelevant.

To evaluate the operationalisation of the dependent variable, we can look at its strengths and weaknesses:

1. **Strength (Objectivity/Reliability):** Counting the number of items in the shopper's cart is a quantitative measure that is completely objective. There is no room for researcher interpretation or bias, meaning different researchers would obtain the exact same tally, ensuring high inter-rater reliability.

2. **Weakness (Construct Validity):** Simply counting items does not fully represent 'purchasing behavior' or consumer spending. For example, a customer buying 2 very expensive items (like premium electronics or high-end spirits) spends much more money and behaves differently than someone buying 12 low-cost grocery items. The count of items does not reflect the monetary value or nature of the purchases.

Marks are awarded for identifying a strength and a weakness of the operationalisation, with application to the supermarket scenario.

- **Strength (Max 2 marks):**
- 1 mark for identifying a valid strength (e.g., highly objective, produces quantitative data, easy to replicate/standardise).
- 1 mark for applying this strength specifically to the supermarket study (e.g., counting physical items at checkout is unambiguous and does not require subjective judgment by the researcher).

- **Weakness (Max 2 marks):**
- 1 mark for identifying a valid weakness (e.g., lacks construct validity, fails to capture the full nature of the variable).
- 1 mark for applying this weakness specifically to the supermarket study (e.g., someone with 2 expensive luxury items is spending more than someone with 15 cheap items, but this difference is lost in a simple item count).

To gain full marks, a response must describe the genetic explanation clearly, referencing genetic inheritance, candidate genes, and relevant research evidence.

- Genetic basis: The idea that OCD runs in families due to genetic transmission.
- Candidate genes: Genes that regulate neurotransmitter systems (like dopamine and serotonin) are implicated.
- Mattheisen et al. (2015): Identified genes such as PTPRD that show significant association with OCD.
- Taj et al. (2013): Found evidence of specific gene variations linked to dopamine receptor function in OCD patients.

Marks are awarded as follows:
- 1 mark: General description of genetic inheritance or family risk.
- 1 mark: Mentioning the role of candidate genes/neurotransmitter regulation.
- 2 marks: Accurate description of specific research evidence (e.g., citing Mattheisen et al., 2015 or Taj et al., 2013, with their relevant findings).

The study by Auty and Lewis (2004) evaluates how implicit memory of product placements influences brand choice.
- Aim: To explore whether product placement in films affects children's choices.
- Sample: Children in two age categories: 6-7 years and 11-12 years.
- Procedure: Experimental group watched 'Home Alone' containing Pepsi; control group watched it with a milk product. Post-viewing, they were offered Pepsi or Coke and interviewed about what they remembered.
- Findings: Those in the Pepsi group showed a significant preference for Pepsi over Coke compared to the control group, demonstrating the effect of implicit product placement.

Marks are awarded as follows:
- 1 mark: Identification of the independent variable / experimental and control group conditions (Pepsi vs. Milk clips).
- 1 mark: Mention of the age groups involved (6-7 and 11-12 years old).
- 1 mark: Explanation of the dependent variable / selection task (choosing between Pepsi and Coca-Cola).
- 1 mark: Key finding (children exposed to Pepsi placement significantly more likely to choose Pepsi).

The explanation centers around Beck's cognitive theory of depression:
- Negative self-schemas: Developed in childhood, acting as a lens through which the individual views new situations.
- Cognitive triad: A pattern of three negative thought channels: self, world, and future.
- Cognitive distortions: Errors in thinking, such as arbitrary inference, overgeneralization, personalization, or minimization, which maintain the negative cycle.

Marks are awarded as follows:
- 1 mark: General statement of the cognitive approach (errors in thinking / negative automatic thoughts).
- 1 mark: Clear description of the Cognitive Triad (self, world, future).
- 1 mark: Explanation of negative self-schemas (including childhood origins).
- 1 mark: Description and example of cognitive distortions (e.g., overgeneralization or selective abstraction).

To answer this question, candidates must define anchoring and outline how it was tested in Wansink et al. (1998).
- Definition: Anchoring acts as a cognitive baseline that influences decision-making, even when the value is arbitrary.
- Study details: Real-world supermarket field experiment on soup cans.
- Conditions: Limits of buying (no limit vs. a limit of 12).
- Results: The high anchor (limit of 12) significantly boosted purchase quantities compared to the control (no limit), showing how purchase limits act as anchors.

Marks are awarded as follows:
- 1 mark: Definition of anchoring as a cognitive bias/heuristic.
- 1 mark: Details of the Wansink et al. (1998) setup (supermarket, soup displays, manipulation of purchasing limits).
- 1 mark: Mention of the specific conditions ('Limit of 12' vs 'No limit').
- 1 mark: Summary of results (high limit anchor increased the average purchase size significantly).

Frith's (1992) cognitive model explains schizophrenia through impaired self-monitoring and executive control:
- Metarepresentation: The cognitive mechanism allowing us to distinguish between internal mental events and external reality. Impairments lead to positive symptoms like hallucinations and passivity phenomena.
- Central Control: The executive function of inhibiting automatic responses. Deficits cause thought disorders, incoherence, and speech derailment.

Marks are awarded as follows:
- 1-2 marks: Outlines the basic concept of impaired cognitive processing/self-monitoring.
- 3-4 marks: Provides detailed descriptions of both metarepresentation (with links to hallucinations/delusions) and central control (with links to disorganized speech/thought patterns).

North et al. (1999) carried out a field experiment to test atmospheric variables on purchase decisions.
- IV: Type of music played (French accordion vs. German brass band).
- DV: Quantity of French vs. German wine purchased.
- Design: Field experiment in a supermarket wine section.
- Key finding: Music significantly biased purchases towards the congruent country of origin (French music led to more French wine sales, German music to more German wine sales).
- Post-purchase questionnaire: Customers were mostly unaware of the musical influence, highlighting the implicit nature of atmospheric cues.

Marks are awarded as follows:
- 1 mark: Outline of the aim and setup (field study in a supermarket wine section testing French vs. German music).
- 1 mark: Detail of the experimental design (alternating French and German music days with similar wines).
- 1 mark: Key finding showing congruent wine sales (French music increased French wine sales; German music increased German wine sales).
- 1 mark: Mention of customer awareness results (customers reported being unaware that music guided their choice).

Description: The AIDA model (Strong, 1925) suggests consumers move through four linear stages during the advertising process: Attention (gaining visual or auditory awareness), Interest (learning about the product's benefits), Desire (developing an emotional want for the product), and Action (making the final purchase). The hierarchy of effects model (Lavidge and Steiner, 1961) outlines six steps grouped into three broader psychological domains: Cognitive (comprising Awareness and Knowledge), Affective (comprising Liking, Preference, and Conviction), and Conative/Behavioral (comprising the Purchase itself). Evaluation: The individual versus situational explanations debate is highly relevant. From an individual perspective, these models rely on active cognitive and emotional processing within the consumer, assuming that personal preferences, existing beliefs, and unique personality traits will dictate whether someone progresses from 'interest' to 'desire'. From a situational perspective, both models assume that the structure, style, and placement of the advertisement itself (external environmental cues) can systematically guide and drive any consumer through the sequence of stages to a predictable purchase action. Other evaluation points include reductionism, as these models simplify complex, non-linear human purchasing patterns into simple steps, and usefulness, as they provide a clear step-by-step framework for marketing firms to monitor the performance of their campaigns.

Description (8 marks):
- 7-8 marks: Description of both the AIDA model and the hierarchy of effects model is highly accurate, detailed, and coherent, showing a thorough understanding of all key stages and psychological domains.
- 5-6 marks: Description of both models is mostly accurate with some detail, or one model is described in detail while the other is only briefly outlined.
- 3-4 marks: Description is basic, lacks detail, or focuses almost entirely on one model with significant omissions.
- 1-2 marks: Description is extremely limited, fragmented, or contains major inaccuracies.

Evaluation (8 marks):
- 7-8 marks: Evaluation is detailed and balanced, containing a thorough discussion of the individual versus situational debate alongside at least one other evaluation point (e.g., usefulness, reductionism), using appropriate psychological terminology.
- 5-6 marks: Evaluation is reasonable, with a clear attempt to discuss individual versus situational explanations, but may lack depth or balance.
- 3-4 marks: Evaluation is basic, mentioning the debate briefly or listing evaluation points without applying them effectively to the models.
- 1-2 marks: Evaluation is superficial, disorganized, or fails to address the individual versus situational debate.

Description: Biological explanations focus on genetic and neurochemical factors. Genetic theories point to twin and family studies showing a higher concordance rate for depression in monozygotic twins. Oruc et al. (1997) investigated DNA polymorphisms in serotonin receptor and transporter genes, showing genetic variation can increase susceptibility to bipolar/unipolar depression, especially in females. The monoamine hypothesis posits that depression is caused by a neurochemical deficit of serotonin, norepinephrine, and dopamine in the synaptic cleft. Cognitive explanations include Beck's cognitive triad, which suggests depressed individuals hold negative schemas about the self, the world, and the future, maintained by cognitive errors like overgeneralisation and selective abstraction. Seligman's learned helplessness and attributional style theory states that individuals learn they cannot control negative events, leading them to explain negative situations using internal, stable, and global attributions. Evaluation: The nature versus nurture debate is a central issue. Biological explanations represent the nature side, proposing that depression is driven by innate biological mechanisms such as genetics and chemical pathways. In contrast, cognitive explanations highlight nurture, suggesting that depressive thought patterns and learned helplessness are acquired through environmental experiences, negative parenting, and life stressors. A comprehensive explanation often relies on the interactionist perspective (diathesis-stress model), where genetic vulnerability (nature) is activated by life events and negative cognitive patterns (nurture). Other evaluation points include reductionism (with biological theories reducing complex mood states to chemical levels) versus holism, and the practical application/usefulness of these explanations in developing treatments such as SSRIs versus Cognitive Behavioral Therapy (CBT).

Description (8 marks):
- 7-8 marks: Description of both biological (genes and neurochemistry) and cognitive (Beck and Seligman) explanations is highly accurate, detailed, and references specific research (e.g., Oruc et al.).
- 5-6 marks: Description of both explanations is mostly accurate with some detail, or one explanation is detailed while the other is outlined briefly.
- 3-4 marks: Description is basic, lacks detail, or focuses on only one explanation with major omissions.
- 1-2 marks: Description is extremely limited, fragmented, or contains major errors.

Evaluation (8 marks):
- 7-8 marks: Evaluation is balanced and detailed, containing a thorough discussion of the nature versus nurture debate and at least one other issue (e.g., reductionism, usefulness), using appropriate psychological terminology.
- 5-6 marks: Evaluation is reasonable, containing a clear attempt to discuss nature versus nurture, but lacks depth or balance.
- 3-4 marks: Evaluation is basic, referencing the nature versus nurture debate briefly or listing evaluation points with poor application.
- 1-2 marks: Evaluation is superficial, disorganized, or fails to address the nature versus nurture debate.

Method: A laboratory experiment using an independent measures design. Independent Variable (IV): The presence of a decoy option. Condition 1 (No Decoy) presents two options: Basic Package ($5 per month) and Premium Package ($10 per month). Condition 2 (With Decoy) presents three options: Basic Package ($5 per month), Decoy Package ($9 per month for web-only access), and Premium Package ($10 per month for web and mobile access). The Decoy is asymmetric: it is clearly inferior to the Premium package but priced almost identically, making the Premium package appear to be a superior value proposition. Dependent Variable (DV): The proportion of participants choosing the Premium Package in each condition. Sample: An opportunity sample of 120 adult participants recruited via social media, randomly allocated to one of the two conditions (60 participants per condition). Procedure: Participants are presented with an online interface for a fictional music streaming service. They are asked to choose one subscription option that they would be most likely to purchase. Controls: Both conditions feature identical branding, visual aesthetics, font, and descriptions of the core features. No time limit is enforced. Data Analysis: A Chi-square test of independence will be used to compare the frequency of choices (Basic vs. Premium) between the two conditions to see if the presence of the decoy significantly increases the selection rate of the Premium package.

Marks are awarded across two main areas: quality of experimental design (5 marks) and application of psychological knowledge (5 marks). [1-2 marks]: Basic design with many key elements missing. Poor understanding of the decoy effect or experimental methodology. [3-5 marks]: Reasonable design. The IV and DV are identified, but operationalisation or controls are weak. Shows some psychological understanding of choice heuristics. [6-8 marks]: Good, replication-ready design. IV, DV, and controls are clearly defined. Explains the decoy structure well. [9-10 marks]: Excellent, highly detailed design. Clearly details the mathematical/pricing relationship of the decoy option (asymmetric dominance), describes rigorous control procedures, identifies sample characteristics, and outlines an appropriate statistical test (e.g., Chi-square).

(a) Example Design:
- Research Method: Field experiment in a natural restaurant environment to ensure high ecological validity.
- Independent Variable (IV): The location of the "chef's special" dessert on the menu. Condition 1: Placed at the very top of the dessert list. Condition 2: Placed at the very bottom of the dessert list.
- Dependent Variable (DV): The proportion of customers ordering the target dessert (calculated as: number of target desserts ordered divided by the total number of desserts ordered under that condition).
- Experimental Design: Independent measures. The restaurant uses Menu A (top placement) during Weeks 1 and 3, and Menu B (bottom placement) during Weeks 2 and 4 to control for potential weekly confounding variables.
- Sample: Real restaurant patrons who dine during the 4-week trial. They are unaware of their participation to avoid demand characteristics.
- Controls: The price, visual design, font size, and written description of the target dessert remain completely identical across both conditions. Waitstaff are instructed to follow a strict script and must not verbally recommend any specific dessert.
- Ethics: Deception is passive (unaware of menu design manipulation). No personally identifiable data is recorded, maintaining complete anonymity.

(b) Psychological Basis:
- The study is rooted in the psychology of choice architecture and intuitive decision-making (System 1 thinking), specifically menu design psychology as studied by Dayan and Bar-Hillel (2011).
- Research shows that consumers do not scan menus systematically; instead, they are subject to order effects. Items placed at the extremes (the very beginning or the very end of a category) receive disproportionately more visual attention, leading to primacy and recency effects.
- By comparing the top position directly against the bottom position, this design tests whether the primacy effect (initial attention at the top) exerts a stronger pull on consumer decision-making than the recency effect (final impression at the bottom) within a realistic food-ordering environment.

Part (a) [10 marks]:
- 8–10 marks: The candidate provides a detailed, coherent, and feasible design for a field experiment. Both the IV and DV are clearly operationalised. Controls (such as waitstaff scripts, matching visual layout, pricing) are highly appropriate. The choice of sample and procedure is realistic and well-explained.
- 5–7 marks: The design is generally sound but lacks specific details in some areas, such as the exact calculation of the DV, control of extraneous variables, or the layout of the menu.
- 1–4 marks: The candidate presents a basic outline with significant omissions. The chosen method may not align with a field experiment, or key experimental features (IV/DV/controls) are missing.

Part (b) [4 marks]:
- 3–4 marks: Explains the psychological basis clearly and accurately, referencing relevant theories of attention, choice heuristics, or specific findings from menu design literature (e.g., Dayan and Bar-Hillel, 2011, and primacy/recency/extremeness effects). The explanation is explicitly linked to the candidate's own design in part (a).
- 1–2 marks: The explanation of psychological principles is superficial, or the link between the theory and the proposed design is weak or missing.
