Reason 1: Control over socialization. Rhesus monkeys lack human-style social conditioning and exposure to gendered marketing (such as TV toy ads). This controls for environmental variables that confound human studies of toy preferences.

Reason 2: Biological/evolutionary comparison. Rhesus monkeys share a high degree of genetic, physiological, and cognitive similarities with humans, allowing researchers to isolate whether sex differences in toy preferences have evolutionary/hormonal roots without human cultural interference.

Award 2 marks for each reason explained:
1 mark for identifying a valid reason.
1 mark for explaining it in the context of the study (e.g., contrasting with human socialization or explaining evolutionary relevance).

Acceptable reasons include:
- Isolation from gender-socialization / toy-specific marketing
- Controlled breeding/rearing histories
- Strong biological/evolutionary parallels to human hormonal and cognitive development
- Practicality in longitudinal/developmental observation.

The MBSR program was an 8-week course that included:
- Weekly group sessions: Eight 2.5-hour group meetings.
- One full-day retreat: A 6.5-hour session during the sixth week of the course.
- Individual home practice: Participants were requested to practice for approximately 45 minutes daily, guided by audio recordings.
- Types of practices: The homework exercises included the body scan (focusing sequentially on different body parts), mindful yoga (stretching and physical awareness), and sitting meditation (mindful breathing and cognitive awareness).

Award 1 mark for each correct, specific descriptive detail of the program, up to a maximum of 4 marks:
- Mention of weekly meetings / 8-week duration / 2.5 hours per session (1 mark)
- Mention of the full-day retreat / 6.5 hours (1 mark)
- Mention of daily home practice / 45-minute sessions (1 mark)
- Mention of specific exercises (body scan, yoga, or sitting meditation) (1 mark)
- Mention of audio recordings used for home practice (1 mark)

Finding 1: In target-present line-ups, children performed similarly to adults. For instance, children did not differ significantly from adults in their rates of correct identification when the target was present (especially for cartoon targets).

Finding 2: In target-absent line-ups, children had a significantly lower correct rejection rate than adults. They were much more likely to incorrectly select a foil (false positive) rather than correctly state that the target was not there.

Award 2 marks for each finding outlined:
1 mark for stating the general finding (e.g., children made more errors in target-absent trials).
1 mark for elaboration/comparison with adults (e.g., specifying that correct rejection rates were lower, or correct identification rates in target-present trials were comparable).

Acceptable findings include:
- Children are as accurate as adults when the target is present.
- Children are significantly worse/less accurate than adults when the target is absent.
- Children have a higher tendency to choose a foil in target-absent conditions due to social pressure to select someone.

The computerized CID paradigm was implemented as follows:
1. The participant was shown a screen where a figure/circle representing themselves was located at the center.
2. Another figure, representing a specific person (e.g., a friend, an acquaintance, a stranger, or an object), was shown at one of the edges of the screen.
3. This second figure began moving inward toward the center figure from one of 8 different entry angles.
4. The participant was instructed to press the spacebar to stop the movement of the figure as soon as they felt uncomfortable with its proximity. The remaining distance (in pixels or as a percentage) was recorded as the operational measure of personal space.

Award 1 mark for each correct, specific descriptive detail of the CID procedure, up to a maximum of 4 marks:
- Description of center figure/circle representing the participant (1 mark)
- Description of approaching figure representing a specific social entity (friend, stranger, etc.) (1 mark)
- Moving from the edge / 8 directions (1 mark)
- Participant pressing the spacebar to stop the figure when feeling uncomfortable (1 mark)
- Measuring the distance in pixels/percentage to quantify personal space preference (1 mark)

Positive reinforcement was operationalized in the study of Asian elephants through several methods:
- Secondary reinforcement: A whistle blow (secondary reinforcer) was established by repeatedly pairing it with primary reinforcers (highly valued food items like bananas, carrots, or apples).
- Immediate reward: When the elephant exhibited the desired target behavior (e.g., presenting a foot through the barrier), the handler blew the whistle immediately and provided the food reward.
- No-reward marker: If the elephant performed an incorrect behavior, no food reward was given, and a low-pitched tone or a brief pause in interaction (no-reward marker) was used instead of any physical punishment.
- Cue training: Hand gestures and verbal cues were used as discriminative stimuli to prompt the specific responses before rewarding.

Award 1 mark for each correct, specific detail of how training with positive reinforcement was conducted, up to a maximum of 4 marks:
- Use of whistle as a secondary reinforcer (1 mark)
- Use of food/bananas/apples/carrots as primary food rewards (1 mark)
- Pairing the whistle blow with the food delivery (1 mark)
- Immediate reward following correct target behavior (e.g. presenting feet) (1 mark)
- Absence of physical punishment / use of a 'no-reward marker' or pause for incorrect behavior (1 mark)

(a) The monotonous tone of voice was chosen to make the task intentionally tedious and unstimulating, which naturally encourages daydreaming or mind-wandering in participants. The specific speed of 227 words per minute was selected to provide a comfortable pace that allowed easy listening and transcription of names without causing excessive cognitive strain or being so slow that it felt unnatural.

(b) Using common, familiar names (e.g., Jane, William) and well-known places (e.g., London, Colchester) acted as a control variable. It prevented confounding variables such as participants struggling to spell or recognize unusual words, which would test language familiarity rather than memory/attention.

For Part (a):
- 1 mark for explaining the purpose of the monotonous tone (to induce boredom / prevent high arousal / encourage daydreaming).
- 1 mark for explaining the purpose of the 227 wpm speed (to ensure standard, comfortable, and understandable audio pace without causing overload/unnatural delay).

For Part (b):
- 1 mark for identifying that it avoids difficulties in spelling or recognition / acts as a control.
- 1 mark for explaining that this ensures memory recall (rather than linguistic skill or vocabulary knowledge) is being accurately measured.

Control 1: Restriction of caffeine and alcohol. Participants were instructed to avoid drinking beverages containing caffeine (e.g., coffee, tea, cola) or alcohol on the day of the study. This controlled for chemical influences that could alter normal sleep stages (REM/NREM duration) and brainwave activity.

Control 2: Standardized awakening method. All participants were awakened using a loud, distinct doorbell placed near the bed. This eliminated situational variables such as the researcher's tone of voice, volume, or physical presence, which might otherwise differentially affect a participant's state of alertness or dream recall.

Award 2 marks for each control outlined:
1 mark for identifying a valid control (situational or participant variable).
1 mark for explaining how it acted as a control (i.e., what confounding variable it prevented, or how it standardizes the procedure).

Acceptable controls include:
- Avoidance of caffeine and/or alcohol (prevents alterations in sleep patterns)
- Standardized loud doorbell for awakening (prevents differences in researcher behavior)
- Sleeping in a quiet, dark laboratory room (prevents external noise/light from disrupting sleep cycles)
- The EEG electrodes being tied in a ponytail-like fashion on the head (prevents them from tangling or waking the participant during movement)

How it was done:
The children were pre-rated by an experimenter and a nursery school teacher (both of whom knew the children well) on four 5-point scales measuring physical aggression, verbal aggression, aggression toward inanimate objects, and aggression inhibition. The scores were summed to create an overall aggression rating.

Why it was done:
This was done to implement a matched pairs design. By grouping children of similar baseline aggression levels and distributing them equally across the experimental conditions (aggressive model, non-aggressive model, control), the researchers controlled for participant variables (pre-existing individual differences in aggression), ensuring that differences in observed aggression were genuinely due to the experimental condition.

Award up to 2 marks for explaining how the pre-rating was done:
- 1 mark for stating that they were rated by two observers (experimenter and teacher) who knew them.
- 1 mark for mentioning the four 5-point scales (or specifying types of aggression measured: physical, verbal, inanimate, inhibition).

Award up to 2 marks for explaining why the pre-rating was done:
- 1 mark for mentioning matched pairs design / equal distribution of aggression across groups.
- 1 mark for explaining that this controlled for participant variables / individual differences in natural aggression levels (preventing confounding).

To obtain full marks, the candidate must describe four distinct aspects of the MBSR program's structure or content. Highly descriptive details include: 1) It was an 8-week program. 2) Group meetings occurred weekly for 2.5 hours. 3) A full-day retreat (6.5 hours) was held during the 6th week. 4) Daily home practice was prescribed for 45 minutes using audio guides. 5) Techniques included the body scan, mindful yoga, and sitting meditation.

1 mark per valid descriptive point about the structure or content of the MBSR program, up to a maximum of 4 marks. Points can include: - It was an 8-week intervention (1 mark). - It featured weekly group sessions (1 mark) that lasted 2.5 hours each (1 mark). - It included a single full-day retreat (1 mark) that lasted 6.5 hours during the 6th week (1 mark). - Participants practiced at home daily (1 mark) for 45 minutes per day (1 mark) using audio recordings (1 mark). - Exercises involved the body scan / mindful yoga / sitting meditation (1 mark for identifying these or 1 mark each if described). - Participants recorded their practice times in a daily diary (1 mark).

STRENGTH 1 (Quantitative Data): The study collected objective, quantitative data through MRI scans, specifically measuring grey matter concentration in cubic millimetres (mm3), and psychometric scores from the Five Facet Mindfulness Questionnaire (FFMQ). This quantitative data allowed researchers to perform precise statistical analyses (e.g., comparing pre- and post-intervention scans) to establish clear biological changes, minimizing researcher bias and increasing the scientific reliability of the findings. STRENGTH 2 (High Control): The research maintained high levels of control. For instance, the scanning parameters were highly standardized using a 1.5 T Magnetom Avanto scanner with a specific automated voxel-based morphometry (VBM) protocol. This ensures that any observed differences in brain structure were caused by the independent variable (the Mindfulness-Based Stress Reduction program) rather than inconsistencies in the imaging process. WEAKNESS 1 (Sample Generalisability): The sample consisted of only 16 participants in the MBSR group and 17 in the control group. Furthermore, participants were self-selected via flyer advertisements. Because this sample is small and consists of individuals already motivated to engage in mindfulness, the findings may not generalize to the wider, less-motivated population. WEAKNESS 2 (Lack of Active Control): The control group was a waitlist control group and did not undergo any active intervention. Consequently, it is difficult to determine whether the changes in grey matter concentration were due specifically to the mindfulness training, or if they were a result of general factors like participating in a regular group activity, expectation of improvement (placebo effect), or other external lifestyle variables during the 8-week period.

Level 4 (8-10 marks): Evaluation is comprehensive, showing an excellent level of understanding of the study. Two strengths and two weaknesses are discussed in detail. At least one strength or weakness directly and effectively addresses the use of quantitative data. The arguments are well-developed, clear, and balanced. Level 3 (5-7 marks): Evaluation is good, showing a solid understanding of the study. Three points (e.g., two strengths and one weakness) are discussed in detail, or four points are discussed but some lack depth. Addresses the use of quantitative data. Level 2 (3-4 marks): Evaluation is limited, showing some understanding of the study. Only two points are discussed, or points are listed without development. May or may not address the use of quantitative data. Level 1 (1-2 marks): Evaluation is basic, showing minimal understanding of the study. Points are highly brief, confused, or irrelevant. Level 0 (0 marks): No creditworthy response.

The researchers used a quantitative self-report measure called the Feelings Thermometer. On this 9-point scale, 0 represented no distress and 8 represented maximum distress. This allowed the boy to provide quantitative ratings for different stimuli, such as rating large plastic buttons as a 2 and small clear plastic buttons as an 8.

1 mark for identifying the self-report tool (Feelings Thermometer). 1 mark for explaining the scale (e.g., 9-point scale / 0 to 8 distress rating). 1 mark for providing an example of a button rating from the study (e.g., rating small clear plastic buttons as an 8, or large plastic buttons as a 2).

A strength of the sample is that rhesus monkeys are cognitively and socially complex primates, making them an excellent model for testing non-human toy preferences. A weakness is the severe gender imbalance, as there were only 11 males compared to 71 females, which reduces the reliability and generalisability of the male-specific data.

1 mark for identifying and explaining a strength of the sample (e.g., developmental/evolutionary similarities to humans). 1 mark for identifying a weakness (e.g., uneven sex ratio of 11 males to 71 females). 1 mark for explaining how this weakness impacts the findings (e.g., limits generalisability of male toy preferences).

Reliability was achieved through standardisation and objectivity. Every participant was scanned using the exact same MRI machine (1.5 Tesla Magnetom Siemens scanner) and head-positioning parameters. Furthermore, the analysis of grey matter density was automated using voxel-based morphometry (VBM) software, which eliminated subjective interpretation and ensured consistent measurements.

1 mark for identifying a standardised feature of the MRI procedure (e.g., same scanner/parameters). 1 mark for identifying the objective analysis tool (voxel-based morphometry software). 1 mark for explaining how this standardisation or objectivity ensures high reliability (e.g., eliminates subjective human bias, allows exact replication).

An independent measures design means different participants are in different conditions, introducing participant variables. In this study, some participants might have naturally superior facial recognition or memory capacities. To control for this, the researchers could have used a matched pairs design, testing participants' memory beforehand and pairing those with similar scores before allocating them to different conditions.

1 mark for identifying participant variables as the disadvantage. 1 mark for contextualising this disadvantage to Pozzulo et al. (e.g., individual differences in memory/facial recognition). 1 mark for suggesting a logical control method (e.g., matching participants based on pre-test memory scores).

Milgram used deception to hide the true aim of the study, which prevented participants from guessing they were being tested on obedience. He provided a cover story that the experiment was about memory and learning. He also structured the setup, including a rigged draw for roles and realistic shock machine, to ensure participants believed the setup was genuine, minimizing demand characteristics.

1 mark for identifying the use of deception/cover story. 1 mark for detail of the cover story (learning and punishment). 1 mark for explaining how this prevented demand characteristics (e.g., by keeping participants blind to the true aim of obedience so they acted naturally).

Fagen et al. ensured high standards of housing and care by keeping the Asian elephants in their existing, naturalistic camp environments. They were housed alongside their normal social groups/companions, preventing isolation distress. Additionally, their daily care, feeding, and bathing routines were maintained, protecting their physical and psychological welfare throughout the study.

1 mark for identifying that they were kept in their familiar camp/naturalistic environments. 1 mark for mentioning they remained with their social companions/groups. 1 mark for mentioning that normal welfare practices (bathing/feeding) were maintained.

(a) Dr. Aris should use a matched pairs design to control for individual differences in baseline phobia severity. If he used an independent measures design, one group might randomly have more severe cynophobia, which would confound the results. Matching participants on their pre-treatment fear scores ensures both treatment groups start with a comparable level of phobia.

(b) The dependent variable could be operationalised using a 10-point Likert scale (where 1 = completely calm, and 10 = extreme panic) in response to imagining being in a room with a dog. A strength of this quantitative measurement is that it provides numerical data that is easy to compare statistically before and after the 6-week treatment course to directly measure improvement.

(c) The primary ethical issue is the protection of participants from psychological harm, as systematic desensitisation involves deliberately exposing participants to their phobic stimulus, which can cause severe anxiety. Dr. Aris can address this by securing fully informed consent beforehand, reminding participants of their right to withdraw at any point without penalty, and ensuring the exposure is gradual and controlled entirely by the participant's comfort level.

(a) Matched pairs vs Independent measures [2 marks]:
- 1 mark: Identifies a relevant participant variable to control (e.g., baseline phobia severity).
- 1 mark: Explains how matching controls this (e.g., ensures equal starting levels across both treatment conditions, preventing participant variables from becoming confounding variables).

(b) Operationalising and strength [3 marks]:
- 1 mark: Provides a clear, operationalised self-report measure (e.g., a specific rating scale measuring anxiety levels).
- 1 mark: Identifies a strength of this scale (e.g., generates quantitative data, allows easy statistical comparison).
- 1 mark: Explains the strength in context of the study (e.g., allows Dr. Aris to directly compare pre- and post-treatment improvement objectively).

(c) Ethical issue and resolution [3 marks]:
- 1 mark: Identifies a relevant ethical issue (e.g., protection from psychological harm/distress when facing phobic stimuli).
- 1 mark: Suggests a realistic way to address it (e.g., right to withdraw, informed consent, therapeutic support).
- 1 mark: Explicitly links the resolution to the context of phobia treatment (e.g., allowing the patient to stop the systematic desensitisation hierarchy if the distress is too high).

(a) The Independent Variable (IV) is the type of office layout (traditional cellular private office vs. open-plan layout). The Dependent Variable (DV) is worker productivity, operationalised as the number of errors made on weekly data-entry tasks.

(b) One potential extraneous variable is the individual data-entry skill or experience level of the employees. If the group in the open-plan office happens to consist of highly experienced staff while the cellular office group has newer employees, the open-plan group might make fewer errors simply due to their skill level rather than the office design. This would lower the internal validity of the study because the researcher cannot be sure if the layout or the skill level caused the difference in error rates.

(c) An advantage of a field experiment is high ecological validity. Because the study takes place in the employees' natural work environment (their actual offices) doing their real tasks, their behavior is much more authentic and representative of real-world productivity. In a laboratory experiment, workers might feel self-conscious or experience demand characteristics, making their performance unnatural and less generalisable to real workplace settings.

(a) Identify IV and DV [2 marks]:
- 1 mark: Correctly identifies the IV (office layout: traditional cellular vs. open-plan).
- 1 mark: Correctly identifies the DV (productivity / number of errors made in data-entry tasks).

(b) Extraneous variable and validity [3 marks]:
- 1 mark: Identifies a plausible extraneous variable (e.g., participant experience, ambient lighting, task difficulty, noise from outside).
- 1 mark: Explains how this variable could affect performance on the task.
- 1 mark: Explicitly links this effect to the internal validity of the research (e.g., making it difficult to establish cause-and-effect between the layout and productivity).

(c) Advantage of field experiment [3 marks]:
- 1 mark: Identifies high ecological validity or reduced demand characteristics as the key advantage.
- 1 mark: Describes what this means (natural behavior in a natural setting).
- 1 mark: Applies the concept directly to this scenario (e.g., workers doing real jobs in their actual workplace, meaning the productivity findings can be directly generalized to real corporate practices).

(a) Leo is using a repeated measures design. This is appropriate because it eliminates participant variables (such as individual differences in natural reading speed, visual acuity, or cognitive processing), ensuring that any difference in the duration of visual attention is caused solely by the position of the logo rather than the traits of the participants.

(b) One major advantage of using an eye-tracking device is that it provides highly objective, precise, and quantitative data (duration of gaze in seconds). This eliminates human bias or errors in observation, and avoids the issues of demand characteristics or retrospective self-report bias, where participants might misremember or misrepresent what they looked at, thus increasing the internal validity of the study.

(c) Leo can use counterbalancing by dividing his participants into two equal groups to control for order effects like fatigue or boredom. Group 1 would view the advertisement with the logo in the top-left corner first, followed by the advertisement with the logo in the bottom-right corner. Group 2 would view the advertisement with the logo in the bottom-right corner first, followed by the logo in the top-left corner. This balances out any potential order or sequence effects across both conditions.

(a) Experimental design [2 marks]:
- 1 mark: Identifies the design as a repeated measures design.
- 1 mark: Explains its appropriateness in context (e.g., controls participant variables like individual visual abilities or reading habits so they don't confound the logo location results).

(b) Advantage of eye-tracking [3 marks]:
- 1 mark: Identifies an advantage (e.g., highly objective, accurate, quantitative, lack of demand characteristics).
- 1 mark: Explains the advantage (e.g., measures actual gaze duration in seconds without relying on subjective self-report or human timing errors).
- 1 mark: Contextualises to this study (e.g., directly measures visual attention to the brand logo placement with scientific precision).

(c) Counterbalancing description [3 marks]:
- 1 mark: Defines counterbalancing or the AB/BA structure.
- 1 mark: Describes how it applies to the two logo conditions (top-left first vs bottom-right first).
- 1 mark: Explains how this controls order effects (e.g., distributes any boredom or practice effects equally across both conditions so they do not systematically skew the results).

Part (a):
An effective design must address:
- Independent Variable (IV): Clear operationalisation of open-plan vs. private cubicles (e.g., layout specifications).
- Dependent Variable (DV): Clear operationalisation of concentration (e.g., error rates, standardized test scores).
- Experimental Design: Independent measures (with random allocation) or repeated measures (with counterbalancing details).
- Controls: Keeping external noise, task difficulty, or time of day constant.
- Procedure: Step-by-step description of how the experiment is executed in a field setting.

Part (b):
- Practical decision: Justification for using a field experiment over a lab study (e.g., ecological validity vs. control over extraneous variables) or choice of measurement.
- Ethical decision: Explanation of how informed consent, deception, protection from harm (e.g., stress from monitoring), or confidentiality is managed and why.

Part (a): [10 marks]
- 9–10 marks: The design is highly appropriate, detailed, and replicable. All key elements (IV, DV, controls, sample, procedure) are clearly operationalised and well-tailored to a field experiment.
- 6–8 marks: The design is mostly complete and appropriate. Most key elements are present, though some aspects may lack operational detail or minor controls are omitted.
- 3–5 marks: The design is basic. It has some appropriate elements, but lacks sufficient detail to be easily replicated, or has major methodological flaws (e.g., confounding variables not controlled).
- 1–2 marks: Suggests a very basic or inappropriate design. Key elements are missing or heavily confused.

Part (b): [4 marks]
- 4 marks: Explains both a practical and an ethical decision clearly, with explicit reference to the proposed study.
- 3 marks: Explains both decisions, but one lacks detail or direct application to the study.
- 2 marks: Explains only one decision in detail, or two decisions very briefly/superficially.
- 1 mark: Identification of a decision with virtually no relevant psychological or methodological explanation.

(a) Applied tension is a physiological treatment technique specifically developed by Lars-Göran Öst for blood-injury-injection (BII) phobia. It involves teaching patients to identify the early physical symptoms of a drop in blood pressure (which leads to fainting, a unique vasovagal response in BII phobia) and actively tensing major muscle groups (such as arms, chest, and legs) to increase blood pressure and prevent fainting.

(b) Ost and Westling (1995) compared Cognitive Behavioral Therapy (CBT) with Applied Relaxation (AR) in the treatment of panic disorder.
- Sample: 38 panic disorder patients, randomly assigned to either CBT (n=19) or AR (n=19).
- CBT group received 12 weekly sessions focusing on:
1. Identifying negative/catastrophic automatic thoughts during panic attacks (e.g., 'I am going to have a heart attack').
2. Cognitive restructuring to challenge and reframe these thoughts with realistic evidence.
3. Behavioral experiments/hyperventilation provocation tests to test the validity of their catastrophic fears in a safe environment.
- Results: Both treatments showed significant reductions in panic attacks, which were maintained at a 1-year follow-up. CBT showed slightly higher, though non-significant, rates of panic-free participants at follow-up (74% CBT vs 65% AR).

(c) Discussion of using CBT to treat anxiety disorders:
Strengths:
- High effectiveness and long-term remission: Helps patients address the cognitive root causes of anxiety rather than just masking symptoms (unlike medication), leading to low relapse rates (as shown in Ost and Westling's 1-year follow-up).
- Empowers the patient: Teaches them self-management skills (cognitive restructuring) that they can use in future anxiety-provoking situations, giving them an internal locus of control.
- Ethics: Lacks the physiological side-effects of drugs (like benzodiazepines, which can be highly addictive).
Weaknesses:
- Requires active participation and commitment: Patients must complete homework, self-monitor panic attacks, and actively engage in cognitive restructuring, which can be challenging for those with severe anxiety or low motivation.
- Time-consuming and expensive: Usually requires 12-16 weekly sessions with a highly trained therapist, making it less accessible than pharmacological treatments.
- Focuses heavily on cognition: May underestimate biological or physiological factors contributing to panic or anxiety.

Part (a): [2 marks]
- 1 mark: Basic/partial explanation of the term (e.g., tensing muscles to stop fainting).
- 2 marks: Full explanation showing a clear understanding of the physiological mechanism (tensing major muscle groups to increase blood pressure and prevent the vasovagal/fainting response typical of BII phobia).

Part (b): [6 marks]
- 5-6 marks: Clear, accurate, and detailed description of the study (sample, CBT treatment components, and key results).
- 3-4 marks: Reasonable description but lacks detail or contains minor inaccuracies.
- 1-2 marks: Basic outline with limited detail.

Part (c): [7 marks]
- 6-7 marks: Balanced discussion of both strengths and weaknesses of CBT, with specific reference to anxiety/panic disorders, structured logically with appropriate psychological terminology.
- 4-5 marks: Discussion of strengths/weaknesses but lacks balance (e.g., only strengths or superficial weaknesses) or lacks specific context/application.
- 1-3 marks: Limited evaluation, lists points without explanation, or relies on generic assertions.

(a) Operator-machine interface (OMI) refers to the design of the interaction between human operators and the machines or systems they control. It focuses on ensuring that controls (buttons, levers, steering wheels) and displays (screens, dials, warning lights) match human sensory and physical capabilities, thereby reducing cognitive load, physical strain, and human error.

(b) Fox et al. (1987) studied the long-term effects of a token economy on safety and accident rates in two open-cast mines (Shirley Basin and Cordero mines).
- Participants: All employees at the mines (including office and operations staff).
- Token economy system: Workers received tokens (trading stamps) for:
- Working in a safe group (no lost-time injuries to any group member).
- Individual safe behavior (no individual lost-time injuries).
- Submitting safety suggestions.
- Preventing injuries or equipment damage.
- Tokens were lost if an employee or group member was injured or caused equipment damage.
- Tokens could be exchanged for a variety of consumer goods at local stores.
- Results: The system led to a massive, immediate, and sustained reduction in lost-time injuries and a significant decrease in the costs associated with accidents and equipment repairs, far outweighing the cost of operating the token economy. The gains were maintained over several years.

(c) Discussion of using token economies in health and safety:
Strengths:
- High ecological validity and effectiveness: Fox et al. demonstrated a massive, sustained reduction in industrial accidents over several years, showing that operant conditioning is highly effective in real-world settings.
- Financial viability: The savings from reduced equipment damage and fewer lost workdays far exceed the operational costs of purchasing stamps/rewards.
- Positive organizational culture: Rewards safe behavior rather than just punishing mistakes, boosting morale and team cohesion.
Weaknesses:
- Risk of under-reporting: Employees might conceal minor injuries or equipment damage to avoid losing tokens for themselves or their work group (due to social pressure).
- Extinction/Sustainment issues: If the token economy is removed, the safe behaviors may diminish as the external reward is gone (lack of intrinsic motivation).
- Generalisability: What works in high-hazard environments like mining may not translate easily to service-oriented or office jobs where safety risks are of a different nature.

Part (a): [2 marks]
- 1 mark: Basic/partial definition (e.g., how humans work with machines).
- 2 marks: Accurate, complete definition mentioning both controls/displays and the match to human capabilities to reduce error/strain.

Part (b): [6 marks]
- 5-6 marks: Comprehensive description of Fox et al.'s study, including the setting, how tokens were earned/lost, and the clear long-term outcomes (safety and financial).
- 3-4 marks: Descriptive but lacks specific details (e.g., omits specific criteria for earning tokens or financial outcomes).
- 1-2 marks: Very basic outline of token economies with little specific reference to Fox et al.

Part (c): [7 marks]
- 6-7 marks: Nuanced and balanced discussion of strengths and weaknesses of token economies in organizational safety, utilizing appropriate psychological concepts (e.g., operant conditioning, peer pressure, under-reporting).
- 4-5 marks: Discusses strengths and weaknesses but lacks depth or specific application to health and safety.
- 1-3 marks: Superficially lists pros/cons with little or no analysis.

(a) Product placement is an advertising technique where branded goods or services are subtly integrated into a media program (such as a movie, television show, or video game) rather than being presented in an explicit commercial advertisement. The goal is to generate implicit brand familiarity and positive associations.

(b) Auty and Lewis (2004) investigated the effect of product placement on children's brand choices and memory.
- Sample: 105 children aged 6-7 (younger group) and 11-12 (older group) from the UK.
- Procedure: Children watched a clip from the movie 'Home Alone' containing prominent product placement for Pepsi (the family is eating pizza and drinking Pepsi, which spills). In the control group, they watched a clip with Milk instead.
- After watching, the children were offered a choice of drink (Pepsi or Coca-Cola) and interviewed about what they remembered from the clip.
- Results: Children in the experimental group (exposed to Pepsi) were significantly more likely to choose Pepsi over Coca-Cola compared to the control group. This effect was found even among children who did not consciously recall seeing Pepsi in the clip, indicating implicit processing. The older children (11-12) recalled the brand significantly more than the younger children (6-7), though both age groups were influenced in their behavior.

(c) Discussion of research into product placement:
Strengths:
- Experimental control: By having a control group (watching the Milk clip) and keeping other factors constant, researchers can establish a causal relationship between product placement exposure and subsequent choice.
- Practical application: Highly useful for marketers and advertisers to understand how early brand preferences are formed and the subconscious power of implicit advertising.
- Developmentally sensitive: Compares different age groups, providing insights into cognitive developmental stages and how children develop advertising literacy.
Weaknesses:
- Low ecological validity: Watching a brief clip in a laboratory/school setting and then immediately being offered a choice of drink does not fully mirror real-world consumer behavior, where exposure is cumulative and choices are influenced by parents, peer pressure, and budget.
- Ethical concerns: Researching how to effectively influence children's subconscious brand choices raises ethical issues, as children are a vulnerable audience who may lack the critical cognitive skills to recognize persuasive intent.
- Short-term measure: The study only measured immediate beverage choice; it does not demonstrate if product placement leads to long-term brand loyalty or sustained consumer habits.

Part (a): [2 marks]
- 1 mark: Basic/partial definition (e.g., showing a brand in a movie).
- 2 marks: Clear and precise explanation (subtly integrating branded products/services into media programs to generate implicit familiarity/association).

Part (b): [6 marks]
- 5-6 marks: Detailed description of the study by Auty and Lewis (2004), including the sample (ages), the experimental manipulation (Home Alone Pepsi vs Milk), and the dual findings (behavioral choice and conscious recall difference between age groups).
- 3-4 marks: Describes the study but with missing details or minor errors.
- 1-2 marks: Minimal details, showing basic awareness of a Pepsi study in a movie.

Part (c): [7 marks]
- 6-7 marks: Well-structured discussion of both strengths and weaknesses, specifically applying evaluation concepts (e.g., ecological validity, ethics, experimental control) to product placement research.

(a) According to Kanner et al. (1981), everyday hassles are the relatively minor, frequent, and irritating demands of daily life (e.g., misplacing keys, traffic jams, minor arguments). They cause stress because of their cumulative effect; constant exposure to small hassles can deplete an individual's coping resources over time, leading to physical and psychological symptoms of stress that can be even more damaging than major life events.

(b) Johansson et al. (1978) measured stress physiologically in Swedish sawmill workers by comparing a high-stress group (finishers, whose work was highly repetitive, machine-paced, and isolated, yet carried high responsibility for the entire mill's output) and a low-stress control group (cleaners, with more flexible and social tasks).
- Physiological measures used:
- Urine samples: Collected throughout the workday to measure levels of stress hormones (adrenaline and noradrenaline).
- Body temperature and self-reports of mood/alertness were also recorded.
- Key findings: The high-stress finishers had significantly higher levels of adrenaline and noradrenaline in their urine than the control group. Furthermore, their hormone levels increased during the workday, whereas the cleaners' levels decreased. This demonstrated that repetitive, machine-paced work creates constant physiological stress activation.

(c) Discussion of physiological measures of stress:
Strengths:
- Objectivity and scientific rigor: Physiological measures (such as urine cortisol/adrenaline levels, heart rate, or blood pressure) are highly objective and scientific. They cannot be easily faked or distorted by social desirability bias, unlike self-report scales where participants might downplay their stress.
- Quantifiability: Provides precise, continuous quantitative data that can be statistically analyzed and easily compared over time or between groups.
Weaknesses:
- Individual differences: Baselines for heart rate, blood pressure, and hormone levels vary widely from person to person. Factors like diet, physical fitness, caffeine consumption, and sleep can confound physiological readings.
- Stress of the measurement itself: Procedures like blood tests or wearing monitoring equipment can be invasive and cause stress in themselves, skewing the results (white-coat effect).
- Lack of psychological context: Physiological measures show that the body is aroused, but they cannot tell us the qualitative nature of the stress or distinguish between distress (negative stress) and eustress (positive excitement/arousal).

Part (a): [2 marks]
- 1 mark: Basic description of everyday hassles (e.g., daily irritations like losing keys).
- 2 marks: Clear explanation of how they cause stress (mentioning the cumulative effect and depletion of coping resources).

- 1-3 marks: Lists basic advantages/disadvantages without meaningful elaboration.

(a) Systematic desensitisation is a behavioral therapy based on classical conditioning principles (reciprocal inhibition). It aims to replace a fear response with a relaxation response. The process involves training the client in deep muscle relaxation, constructing an anxiety hierarchy of the feared stimulus (from least to most frightening), and gradually exposing the client to each level of the hierarchy while maintaining a relaxed state.

(b) The cognitive explanation, supported by Di Nardo et al. (1988), suggests that phobias are maintained by irrational thought processes, negative cognitive appraisals, and distorted expectations of harm. In their study on dog-phobic and non-phobic individuals, they found that both groups had experienced painful experiences with dogs, but only the phobic group developed a strong expectation that dogs would cause them harm or pain in the future. This indicates that it is the cognitive interpretation and expectation of negative outcomes (rather than the traumatic conditioning event itself) that leads to and maintains the phobia.

(c) Applied tension (developed by Öst) is a technique where individuals tense their major muscle groups (arms, chest, legs) to increase blood pressure, which prevents fainting. This would NOT be suitable for Clara. Acrophobia (fear of heights) is characterized by sympathetic nervous system arousal (increased heart rate and anxiety), rather than a sudden drop in blood pressure and fainting (vasovagal response) which is unique to blood-injury-injection phobia. Therefore, systematic desensitisation, which aims to lower arousal, is highly suitable, whereas applied tension would inappropriately increase her cardiovascular arousal.

(d) Strengths of behavioral treatments:
- They are highly effective and have high success rates for specific phobias.
- They are quicker and require less verbal-cognitive insight compared to psychoanalysis or CBT, making them accessible to a wider demographic (e.g., children or people with communication difficulties).
- Ethical strength: Systematic desensitisation is client-led; the patient determines the pace of the hierarchy, giving them control and reducing stress compared to flooding.

Weaknesses of behavioral treatments:
- They only treat the physical symptoms of the phobia rather than the underlying root cause. This can lead to symptom substitution (where a new phobia develops in place of the old one).
- They require high commitment and emotional resilience from the client to face their fears, which may lead to high drop-out rates.
- In vitro (imagined) exposure within systematic desensitisation may not generalise effectively to real-world (in vivo) situations.

(a)
- 1 mark: Identifies the theoretical basis (classical conditioning / reciprocal inhibition / replacing fear with relaxation).
- 1 mark: Outlines the steps (relaxation training + anxiety hierarchy + gradual exposure).

(b)
- 1-2 marks: Outline of the cognitive explanation (focus on irrational thinking, negative appraisals, and expectation of harm).
- 3-4 marks: Clear description of the Di Nardo et al. (1988) study (e.g., comparing dog phobics and non-phobics, findings about equal trauma but different cognitive expectations/expectancy of harm).

- 1 mark: Clear definition of applied tension (tensing muscles to raise blood pressure).
- 1 mark: Application to Clara's case (explains that she has acrophobia, which raises heart rate/blood pressure).
- 1 mark: Explicit conclusion on suitability (not suitable because it is designed for blood-injury-injection phobia to prevent fainting/syncope, whereas Clara needs to relax and lower her arousal).

(d)
- 1-2 marks: Minimal discussion. Basic points made about behavioral treatments, lacking detail or evaluation structure.
- 3-4 marks: Good discussion of both strengths and weaknesses, but may lack balance or depth of examples/links to the syllabus.
- 5-6 marks: Balanced, detailed, and well-structured discussion of both strengths and weaknesses of behavioral treatments (such as systematic desensitisation) using appropriate psychological terminology.

(a) A rapid rotation shift pattern (sometimes called metropolitan or continental rotation) is a temporal work schedule where employees change shifts frequently, such as working 2 morning shifts, 2 afternoon shifts, 2 night shifts, followed by 2 days off. This rapid adjustment prevents the body's circadian rhythm from fully adapting to a night schedule, keeping the worker anchored to normal social/diurnal rhythms on their days off.

(b) Fox et al. (1987) implemented a token economy system in open-cast coal mines to reduce accidents. Workers earned stamp tokens for behaviors that promoted safety, such as working without lost-time injuries, preventing damage to equipment, making helpful safety suggestions, or actively preventing injuries. These tokens could be exchanged for items at an on-site redemption store (e.g., household appliances, outdoor gear). There were also penalities where tokens were lost if any group member was injured or caused equipment damage. The system led to a significant and sustained reduction in lost-time injuries, days lost from work, and overall accident costs over several years.

(c) One alternative is safety promotion campaigns/posters. This approach uses visual media and persuasive communication to increase workers' safety awareness. For example, campaigns can use fear appeals or positive role models to encourage compliance with safety behaviors (like wearing personal protective equipment). Another alternative is ergonomic design, where machinery and workstations are physically altered to make human error physically impossible or less damaging (e.g., requiring two buttons to be pressed simultaneously to operate a stamp machine, ensuring hands are clear of danger).

(d) Strengths of changing physical or temporal conditions:
- High reliability: Physical alterations (e.g., improved illumination or safety guards) and structured shift patterns are permanent and do not depend on continuous human compliance or motivation to be effective.
- Prevention of physiological fatigue: Designing optimal shift rotations (like avoiding long night shifts or using slow/rapid rotation appropriately) aligns with human biology and circadian rhythms, which directly reduces errors caused by sleep deprivation.
- Large-scale impact: Changing conditions affects all workers simultaneously, creating a safer default environment for the entire workforce.

Weaknesses of changing physical or temporal conditions:
- High financial cost: Altering physical layouts, upgrading lighting, or redesigning shift schedules (which might require hiring more staff) requires substantial capital investment.
- Disruption to social lives: Changes in shift patterns, even if biologically beneficial (such as slow rotation), can severely disrupt workers' family lives and social patterns, potentially decreasing job satisfaction and increasing turnover.
- Individual differences: Not all workers adapt to shift changes in the same way; some individuals are 'morning types' (larks) and others are 'evening types' (owls), meaning standardized shifts will never suit everyone.

(a)
- 1 mark: Identifies the frequent changing of shifts (e.g., every 2 or 3 days).
- 1 mark: Mentions the purpose or an example of a pattern (e.g., 2 mornings, 2 afternoons, 2 nights; prevents circadian adaptation).

- 2 marks: Explains how the alternative reduces accidents.
- 3 marks: Fully explains the alternative, clearly contrasting its mechanism (e.g., cognitive/persuasive or physical) with the behavioral token economy approach.

(d)

- 5-6 marks: Balanced, analytical evaluation of changing physical or temporal conditions. Covers both productivity and safety with appropriate examples (e.g., circadian rhythms, financial cost, ergonomics).

### Part (a) Suggested Design

* **Aim:** To investigate whether the tempo of instrumental background music affects the average monetary spend of supermarket shoppers.
* **Research Method:** A field experiment conducted in a real, functioning supermarket.
* **Experimental Design:** Independent measures design. Shoppers will experience either the fast-tempo condition or the slow-tempo condition.
* **Independent Variable (IV):** The tempo of the background music, operationalised as:
* Condition 1: Fast tempo instrumental music (120 beats per minute [BPM]).
* Condition 2: Slow tempo instrumental music (60 beats per minute [BPM]).
* **Dependent Variable (DV):** The average amount of money spent per customer, measured in dollars ($) using anonymous sales receipt data obtained from the point of sale (checkout).
* **Sample and Sampling Method:** An opportunity sample of shoppers entering a mid-sized supermarket during a two-week period. To control for confounding variables like weekday/weekend spending habits, the conditions will be counterbalanced (e.g., fast tempo on Monday/Wednesday/Friday of Week 1 and Tuesday/Thursday/Saturday of Week 2; slow tempo on the opposite days). Only shoppers who shop alone will be included to avoid social influence on spending.
* **Controls and Standardisation:**
* The playlist will consist of instrumental, non-vocal jazz/ambient music to prevent lyrics from influencing behavior.
* The volume of the music will be kept constant at a moderate level of 60 decibels throughout the store.
* Store lighting, temperature, and product placements will remain completely unchanged across both conditions.
* Times of testing will be standard operating hours (09:00 to 18:00).
* **Procedure:**
1. Before the study begins, permission is obtained from the supermarket management.
2. On designated 'slow tempo' days, the 60 BPM playlist is played continuously. On 'fast tempo' days, the 120 BPM playlist is played.
3. Researchers station themselves near the checkout area to observe and record data.
4. A systematic sampling technique is used where every 5th customer shopping alone is approached at the exit after paying.
5. They are asked if they would mind sharing their receipt for an anonymous academic study on shopping patterns. No mention of music is made to avoid demand characteristics.
6. If they agree, the total expenditure on the receipt is recorded alongside the day/time. The receipt is returned, and no personal identifiable information is collected.
7. Data is analyzed using an independent t-test to compare the mean spending between the two music conditions.

### Part (b) Explanation of Evidence

* **Methodological Evidence:**
* **Field Experiment:** Conducted in a real supermarket. This increases ecological validity as shoppers are behaving naturally in a real-world setting, meaning their spending behavior is representative of genuine consumer actions.
* **Independent Measures:** Avoids order effects (e.g., fatigue or practice) as each shopper is only exposed to one music tempo condition during their trip.
* **Ethical Considerations:** Informed consent is obtained post-trip before collecting receipt data, maintaining the ethical right to withdraw. To avoid demand characteristics, deception is used regarding the true aim (shoppers are told it is a study on 'general shopping patterns' rather than music).
* **Standardisation:** Controlling volume (60 dB) and using instrumental music ensures that variables other than tempo do not confound the results.

* **Psychological Evidence:**
* **Milliman (1982):** This study is the primary basis. Milliman investigated the effect of background music tempo on consumer behavior in a supermarket. He found that slow-tempo music slowed down the pace of flow through the store, which in turn increased sales significantly compared to fast-tempo music.
* **Cognitive/Behavioral Mechanism:** Slow music is hypothesized to reduce physiological arousal, leading consumers to walk slower, spend more time browsing shelves, and consequently make more unplanned impulse purchases. Fast music increases arousal and the speed of movement, leading to quicker exits and lower spending.

### Part (a) [10 Marks]
* **8–10 marks:** The design is highly appropriate, detailed, and clearly structured. It explicitly operationalises the IV, DV, sample, controls, and procedure. The methodology is highly realistic and appropriate for a field study.
* **5–7 marks:** The design is mostly appropriate with some good detail. Some key elements (e.g., controls or specific operationalisation of variables) may be lacking or slightly unrealistic.
* **3–4 marks:** The design is basic. It has omissions of major elements, or lacks clarity on how the variables are manipulated/measured.
* **1–2 marks:** Very weak attempt. The design is muddled, lacks relevant details, or is inappropriate for the specified scenario.

### Part (b) [8 Marks]
* **7–8 marks:** Excellent explanation of both methodological decisions (e.g., why field experiment, ethics, sample choice) and psychological evidence (e.g., Milliman's study, environmental psychology theories regarding tempo, arousal, and consumer pacing).
* **5–6 marks:** Good explanation. Mentions both methodological and psychological evidence, but one may be significantly stronger or more detailed than the other.
* **3–4 marks:** Limited explanation. Focuses mostly on either methodological or psychological aspects, with basic or superficial links to the proposed study.
* **1–2 marks:** Anecdotal or highly incomplete explanation with little to no clear reference to established psychological studies or methodological principles.

To answer this question, candidates should discuss both sides of the debate regarding how consumers make decisions when buying high-value items (such as cars, property, or high-end electronics).

### Arguments in agreement with the statement (Rational/System 2 decisions):
- **System 2 thinking (Kahneman):** This form of thinking is slow, deliberate, effortful, and logical. Since high-value items represent significant financial risk, consumers are highly motivated to employ cognitive effort, conduct thorough research, and carefully compare alternatives.
- **Utility Theory:** Classic economic models suggest that consumers seek to maximise utility. When purchasing high-value goods, they are more likely to perform a cost-benefit analysis (subjective expected utility) to ensure the choice delivers the highest possible value.
- **Sproles and Kendall's Consumer Style Inventory (CSI):** Certain consumer profiles (e.g., the high-quality/perfectionist or price-conscious consumer) rely on systematic, structured comparisons, particularly when purchasing expensive goods to ensure value for money.
- **Non-compensatory strategies (e.g., Elimination by Aspects):** Consumers purchasing complex, expensive goods often use systematic rules to eliminate options that do not meet specific criteria (e.g., rejecting cars without a five-star safety rating).

### Arguments against the statement (Irrational/System 1 decisions/Heuristics):
- **System 1 thinking (Kahneman):** This is fast, automatic, emotional, and unconscious. Even for high-value items, emotional reactions (e.g., the status appeal of a luxury brand, aesthetic preference, or the 'feeling' of driving a car) can dominate the choice, with System 2 logic only used post-purchase to rationalise the decision.
- **Bounded Rationality and Satisficing (Simon):** Consumers do not have infinite cognitive capacity or access to perfect information. Even when buying high-value items, they may opt to 'satisfice' (choose the first option that meets their basic requirements) rather than optimize.
- **Prospect Theory (Kahneman & Tversky):** Decisions are heavily influenced by framing and loss aversion rather than objective rationality. For example, a consumer might buy an overpriced extended warranty on an expensive appliance due to fear of future loss.
- **Heuristics and Biases:**
- *Anchoring:* Consumers can be biased by an initial high 'suggested retail price' and believe they are getting a great deal, ignoring objective value.
- *Social Proof/Availability:* Choosing an expensive brand simply because it is highly visible or recommended by peers, rather than based on independent logical evaluation.

The essay should be marked using the following 12-mark holistic grading criteria for Paper 4 Section C:

**Level 4 (10–12 marks):**
- Both sides of the argument are considered in detail.
- Excellent psychological knowledge and understanding of consumer decision-making models (e.g., Kahneman's System 1 and 2, utility theory, heuristics, satisficing) are demonstrated.
- The discussion is well-structured, coherent, and uses precise psychological terminology.
