2026 Cambridge IAL Psychology (9990) 模拟试题及答案详解

In Andrade's study, the doodling group received an A4 sheet with printed shapes (squares and circles) and pencil. They were instructed to:
1. Shade in the printed shapes (and were told it didn't matter how neatly or quickly they did it / it was just to relieve boredom).
2. Listen to the mock telephone message and write down the names of people who definitely said they could attend the party, while ignoring irrelevant names and information.

1 mark per correct instruction outlined, up to a maximum of 2 marks.

• Shade in the printed shapes / doodle while listening (1 mark)
• Do not worry about neatness / speed of shading / do it just to relieve boredom (1 mark)
• Write down the names of the people who are coming to the party (1 mark)
• Ignore the names of people who cannot come / ignore any other information (1 mark)

Participants were woken up by a loud doorbell/buzzer. They immediately spoke into a dictaphone / tape recorder located right beside the bed. They first stated whether they had been having a dream or not, and if they had, they described the details and content of their dream into the recorder without an experimenter entering the room (unless further questioning was needed).

1 mark per procedural detail of how dream recall was recorded, up to a maximum of 2 marks.

• Awakened by a loud doorbell / buzzer (1 mark)
• Spoke into a tape recorder / dictaphone / audio device beside the bed (1 mark)
• Stated whether they had been dreaming or not (1 mark)
• Described the content / details of their dream if they remembered it (1 mark)
• No experimenter entered the room immediately (to avoid influencing recall) (1 mark)

Bandura et al. standardized specific novel aggressive verbal phrases so that imitative aggression could be clearly differentiated from non-imitative aggression. The model repeated phrases such as "Sock him in the nose", "Hit him down", "Throw him in the air", "Kick him", and "Pow".

1 mark per correct aggressive verbal phrase identified, up to a maximum of 2 marks.

• "Sock him in the nose" (1 mark)
• "Hit him down" / "Hit him" (1 mark)
• "Throw him in the air" (1 mark)
• "Kick him" (1 mark)
• "Pow" (1 mark)

Note: Allow minor variations in phrasing as long as the distinct syllabus phrase is recognizable.

Milgram designed four standardized verbal prods delivered in sequence whenever the teacher/participant protested or showed hesitation:
- Prod 1: "Please continue" or "Please go on."
- Prod 2: "The experiment requires that you continue."
- Prod 3: "It is absolutely essential that you continue."
- Prod 4: "You have no other choice, you must go on."

1 mark per correct verbal prod outlined, up to a maximum of 2 marks.

• Prod 1: "Please continue" / "Please go on" (1 mark)
• Prod 2: "The experiment requires that you continue" (1 mark)
• Prod 3: "It is absolutely essential that you continue" (1 mark)
• Prod 4: "You have no other choice, you must go on" (1 mark)

Note: Sequences/prod numbers do not need to be identified, but the wording must accurately reflect the prods used.

The MBSR course consisted of several structured components:
1. Weekly group sessions lasting 2.5 hours covering mindfulness meditation exercises (body scan, sitting meditation, yoga) and discussion.
2. Daily home practice for roughly 45 minutes per day using guided audio recordings.
3. A full-day mindfulness retreat (around 6 hours) held during the sixth week of the programme.

1 mark per correct component outlined, up to a maximum of 2 marks.

• Weekly 2.5-hour group meetings/classes (focusing on mindfulness/meditation practice) (1 mark)
• Daily home practice (approx. 45 minutes per day) using guided audio recordings (1 mark)
• A full-day retreat (6-hour silent retreat) during the sixth week of the course (1 mark)
• Specific mindfulness exercises: body scan / sitting meditation / mindful yoga (1 mark)

During the imagery exposure (disgust-related) sessions, the boy engaged in imaginal exposure rather than handling physical buttons. He was asked to visualize scenarios involving buttons (e.g., hundreds of buttons falling all over him, hugs with people wearing buttons) and imagine their touch, smell, and appearance. He was guided to use self-control statements and cognitive restructuring to explore what made them disgusting, and he rated his distress using the Feelings Thermometer.

1 mark for detail of imagery visualization;
1 mark for detail of cognitive strategy / emotional rating / distress management.

• Visualise / imagine buttons falling on him / imagine how buttons look, feel, and smell (1 mark)
• Pair mental images with positive self-talk / cognitive self-control strategies (1 mark)
• Rate his distress/disgust using the 9-point Feelings Thermometer (1 mark)

In Pozzulo et al., both line-ups consisted of 6 photographs (1 target/replacement + 5 foils):
- In the target-present (TP) condition, the perpetrator/target seen in the original video clip was included in the line-up alongside five innocent distractors/foils.
- In the target-absent (TA) condition, the actual target was omitted and replaced with an innocent replacement foil who matched the general description of the target, alongside the other five foils.

1 mark for outlining the target-present line-up;
1 mark for outlining the target-absent line-up.

• Target-present line-up: Contains the actual target / perpetrator / culprit seen in the video clip alongside foils (1 mark)
• Target-absent line-up: The actual target is absent/removed and replaced by an innocent person / replacement foil matching the general description (1 mark)

The victim's appearance and props were manipulated to create the two conditions:
- In the 'ill' condition, the victim appeared sober and carried a black walking cane.
- In the 'drunk' condition, the victim smelled of alcohol / liquor and carried a liquor bottle inside a brown paper bag.

1 mark for describing the 'ill' condition;
1 mark for describing the 'drunk' condition.

• Ill victim: carried a black cane / walking stick (and appeared sober) (1 mark)
• Drunk victim: smelled of alcohol / liquor AND/OR carried a bottle wrapped in a brown paper bag (1 mark)

Suggestion 1: Farah could supply employees with paper containing pre-drawn shapes (e.g. squares and circles) and pencils, encouraging them to shade the shapes while listening to the presentation.
Explanation 1: In Andrade's study, doodling engaged the brain at an optimal level of arousal, preventing daydreaming (which consumes significant central executive capacity) and enhancing attention, resulting in 29% more information recalled.

Suggestion 2: Farah should ensure the doodling task is simple/structured and does not require complex creative drawing or conscious decision-making.
Explanation 2: Andrade showed that simple, non-demanding visual tasks aid auditory processing; if the secondary task is too complex, it would create cognitive interference and overload executive resources, reducing recall.

Apply point-based marking:
- 1 mark for each practical suggestion linked to the scenario / Andrade's study (up to 2 marks).
- 1 mark for each psychological explanation / justification referencing Andrade's findings or theory (optimal arousal, reducing daydreaming, dual-task processing) (up to 2 marks).

Example points:
- Suggestion: Provide printed sheets with geometric shapes and tell staff to shade them while listening (1 mark).
- Explanation: Doodling prevents daydreaming / maintains optimal cognitive arousal, allowing more auditory details to be processed into memory (1 mark).
- Suggestion: Allow employees to doodle rather than forcing strict quiet attention (1 mark).
- Explanation: Andrade found doodling participants recalled significantly more monitored and incidental information than non-doodlers (1 mark).

Technique 1: Use of secondary reinforcers and primary positive rewards.
Dominic can establish a secondary reinforcer (such as a clicker sound or short whistle blast) by pairing it with a high-value primary reward (e.g. a small piece of apple or carrot). As soon as the horse produces the target movement, Dominic clicks instantly to bridge the time gap before delivering the food reward, reinforcing the exact behavioural response as demonstrated by Fagen et al.

Technique 2: Behavioural shaping (successive approximations).
Dominic can break down the complex target behaviour into small sequential steps. He should first reward the horse for simply shifting its body weight away from the target leg, then reward lifting the hoof off the ground, and finally reward allowing the hoof to be held and inspected, only giving the secondary reinforcer when the horse meets each progressive criterion.

Apply point-based marking:
- 1 mark for suggesting the use of a secondary reinforcer / bridge paired with a primary reward (1 mark: application).
- 1 mark for explaining/justifying the timing or mechanism of positive reinforcement (1 mark: justification).
- 1 mark for suggesting shaping / behavioural chaining / successive approximations (1 mark: application).
- 1 mark for explaining/justifying how breaking the behaviour into steps allows the animal to achieve the target response without force (1 mark: justification).

Technique 1: In vivo exposure with positive reinforcement (contingency management).
Kiran can create a Feelings Thermometer / hierarchy of balloon stimuli (e.g., looking at a picture of a balloon, touching a deflated balloon, standing near a fully inflated balloon, holding a balloon). Kiran then guides Leo through gradual physical exposure to each step, while Leo's mother provides positive reinforcement (praise, stickers, or small rewards) every time Leo successfully tolerates contact without distress.

Technique 2: Disgust-related imagery exposure and cognitive restructuring.
Because phobias often involve evaluative learning and disgust, Kiran can ask Leo to close his eyes and imagine holding, hugging, and touching balloons while visualising them as harmless and soft rather than dangerous. Kiran helps Leo identify his specific disgust thoughts (e.g., expecting an unbearable loud pop) and replace them with coping self-statements while using deep breathing to reduce subjective distress ratings.

Apply point-based marking:
- 1 mark for identifying behavioural exposure / contingency management linked to the scenario (1 mark).
- 1 mark for explaining how behavioural exposure is implemented with Leo (e.g. hierarchy of balloons, positive reinforcement / praise) (1 mark).
- 1 mark for identifying disgust-related imagery exposure / cognitive restructuring linked to the scenario (1 mark).
- 1 mark for explaining how imagery exposure is implemented with Leo (e.g. imagining touching balloons, targeting evaluative disgust, self-talk/reassurance) (1 mark).

Suggestion 1: Reduce the perceived costs of helping and increase the costs of not helping (cost-reward arousal model).
The company can display clear instructional posters showing simple steps to help someone who collapses (e.g., putting them in the recovery position, pressing the carriage alarm). Piliavin et al.'s cost-reward model indicates that helping increases when the personal cost of helping (e.g. fear of making a medical mistake, fear of personal harm) is minimised and confidence in intervening is high.

Suggestion 2: Introduce early intervention models (e.g. trained commuter ambassadors or visible onboard staff).
The company could place trained staff or peer volunteers on trains who are instructed to step forward immediately if someone falls. Piliavin et al. found that when an early model stepped in (after 70 seconds), it broke the bystander hesitation and significantly increased subsequent helping from other passengers compared to when no model or a late model was present.

Apply point-based marking:
- 1 mark for each practical suggestion linked to the railway/passenger scenario (up to 2 marks).
- 1 mark for each psychological explanation referencing Piliavin et al. (e.g., cost-reward model of bystander behaviour, effect of early vs. late modelling, victim clarity/cues) (up to 2 marks).

Example points:
- Suggestion: Place clear first-aid instructions/alarms to make helping easy and safe (1 mark).
- Explanation: Lowers the personal cost of helping in the cost-reward model, making bystanders quicker to assist (1 mark).
- Suggestion: Train designated regular travellers/staff to initiate help immediately (1 mark).
- Explanation: Piliavin showed an early model setting an example facilitates further helping from nearby passengers (1 mark).

Example full-mark response:

Similarity: Use of an independent measures experimental design
One similarity is that both studies utilized an independent measures design, where participants were allocated to separate groups and only took part in one experimental condition.
- In Andrade's study, participants were randomly allocated to either the doodling condition (shading printed shapes while listening to a mock telephone message) or the control condition (listening to the message without doodling).
- Similarly, in Pozzulo et al.'s study, participants were randomly allocated to either the target-present line-up condition or the target-absent line-up condition for both human and cartoon faces.
This design prevented order effects, such as practice or fatigue, from distorting the recall or identification performance of participants in both investigations.

Difference: Demographic composition of the sample (use of child participants vs. adult-only sample)
One difference between the two studies is the demographic age profile of the participants.
- Pozzulo et al. included children (aged 4–7 years) alongside adults (aged 17–30 years) to investigate developmental differences in eyewitness identification and false-positive choices.
- In contrast, Andrade used an exclusively adult sample (aged 18–55 years) recruited from the Medical Research Council applied psychology unit participant panel.
Consequently, Pozzulo et al. had to implement child-friendly procedural modifications (such as using cartoon characters and simplified instructions) and consider developmental ethics, whereas Andrade did not involve child participants.

Level 4 (7–8 marks):
- Clear, detailed explanation of one similarity and one difference.
- Explicit, accurate, and balanced links made to both the study by Andrade and the study by Pozzulo et al. for each point.
- Effective use of psychological terminology.

Level 3 (5–6 marks):
- Good explanation of one similarity and one difference with contextual links to both studies, though one comparison may be more developed than the other.
- OR clear and detailed explanation of only one similarity OR one difference with comprehensive links to both studies (maximum 5 marks).
- Appropriate use of psychological terminology.

Level 2 (3–4 marks):
- Limited comparison. Points identify a similarity and/or difference, but elaboration or contextual application to one or both studies is brief, muddled, or descriptive.
- Psychological terminology used partially or with minor inaccuracies.

Level 1 (1–2 marks):
- Very basic or fragmented points.
- Identifies a similarity/difference without appropriate contextual links to the studies, or simply describes elements of the studies without direct comparison.

Level 0 (0 marks):
- No creditable response (e.g. refers only to the cognitive approach which is excluded by the stem, or completely incorrect facts).

Indicative content:
Similarities:
- Experimental method (both are laboratory experiments with standardized controls).
- Independent measures design.
- Data collection type (both collected objective quantitative data: number of names/places recalled vs. correct identification rates/false positive rates).
- High control of extraneous variables (e.g., standard audio recording at 187 wpm in Andrade; standardized video clips and photo arrays in Pozzulo et al.).

Differences:
- Sample age/developmental groups (Andrade tested adults aged 18–55; Pozzulo et al. compared young children aged 4–7 to adult university students).
- Nature of the task / target stimuli (listening to auditory monotonous text in Andrade vs. viewing visual video clips of human targets and cartoon characters in Pozzulo et al.).
- Sampling technique (Andrade used a volunteer panel originally recruited for another study / opportunity; Pozzulo et al. recruited children from daycares and adults from an undergraduate university participant pool).

Indicative content for evaluation:

1. Named Issue: The use of children in psychological research
- Ethical considerations: Children are a vulnerable group who may find the exposure to phobic stimuli distressing (e.g. imagining buttons falling on him, handling increasing numbers of buttons). However, the intervention had direct therapeutic benefit, completely curing the child's phobia and distress.
- Consent and assent: Valid informed consent was provided by the mother, and the 9-year-old boy gave his assent to participate and undertake the behavioural exposure and imagery sessions.
- Demand characteristics and vulnerability: Children may be more susceptible to social desirability or wanting to please adult authority figures (the therapists/mother), potentially exaggerating improvements on the Feelings Thermometer. However, the boy was able to report genuine distress levels across different button types (e.g. rating small clear plastic buttons as highest distress at 8).

2. Strengths of the study:
- Rich qualitative and quantitative data: Quantitative data collected using the 9-point Feelings Thermometer (0–8) allowed objective tracking of progress and severity reduction. Detailed qualitative data provided rich clinical insights into the etiology of the phobia (the bowl of buttons falling on him in kindergarten) and the nature of his disgust cognitions.
- Ecological validity of treatment and longitudinal follow-up: The therapy addressed real-life functional impairment (school uniform, hugging mother). Follow-up assessments at 6 and 12 months demonstrated long-term maintenance of treatment gains with no button-related distress.

3. Weaknesses of the study:
- Generalisability / Case study limitations: The sample consisted of a single 9-year-old Hispanic-American boy with a specific phobia triggered by a unique traumatic event. Findings may not generalise to other types of phobias, adult populations, or different cultural backgrounds.
- Subjectivity and researcher bias: As an intensive clinical case study, the close rapport built between researchers and participant may have introduced subjective bias into the interpretation of qualitative self-reports. Self-report ratings of disgust and fear are inherently subjective.

Level 4 (8–10 marks):
• Detailed and balanced evaluation covering strengths and weaknesses.
• Clear and effective discussion of the named issue (the use of children in psychological research) integrated throughout.
• Arguments are explicitly contextualised using specific details from Saavedra and Silverman.
• Clear structure, logical progression, and mature psychological terminology.

Level 3 (5–7 marks):
• Good evaluation with at least two distinct points (strengths/weaknesses).
• Discussion of the named issue is present and linked to the study.
• Points are generally well explained with relevant examples from the study.
• Sound structure and appropriate use of psychological concepts.

Level 2 (3–4 marks):
• Basic evaluation; may focus only on strengths or weaknesses, or points are underdeveloped.
• Discussion of the named issue is brief, superficial, or omitted (Note: answers that do not address the named issue are capped at a maximum of 4 marks / Level 2).
• Limited contextual detail from the study.

Level 1 (1–2 marks):
• Minimal evaluative commentary; mostly descriptive or list-like.
• Lacks depth, clarity, and specific application.

Level 0 (0 marks):
• No creditable response.

An independent measures design is an experimental design where separate groups of participants are allocated to each condition/level of the independent variable. This means each participant experiences only one condition of the study, preventing order effects such as practice or fatigue.

1 mark for a basic/incomplete definition (e.g. 'different people are in different groups').
2 marks for a clear, complete definition referring to separate participants performing in each condition / level of the IV.

Example answer: An experimental design where different participants take part in each level/condition of the independent variable (2 marks).

A directional (one-tailed) hypothesis is a statement that predicts the specific nature or direction of the effect/difference between conditions or the relationship between co-variables (e.g. stating that scores will be higher in one condition, or that a positive correlation will exist), usually formulated when previous research suggests a clear outcome.

1 mark for a basic outline (e.g. 'a prediction that states what will happen').
2 marks for a detailed/complete outline explicitly identifying that it predicts the specific direction/nature of the difference or relationship.

Example answer: A hypothesis that states the specific direction of the outcome or difference between conditions (1 mark), such as one group scoring higher than another (1 mark).

Demand characteristics refer to environmental or procedural cues in an experiment that convey the researcher's hypotheses or expectations to participants. As a result, participants may alter their normal behaviour (either trying to help confirm the hypothesis or doing the opposite), which reduces internal validity.

1 mark for a basic description (e.g. 'when participants guess the aim').
2 marks for an elaborated definition explaining how cues cause participants to guess the aim and change their behaviour.

Example answer: Features of an experiment that give away the aims to participants (1 mark), causing them to change their natural behaviour to match expectations (1 mark).

Inter-rater (or inter-observer) reliability is the degree of consistency and agreement between two or more independent researchers who code or assess the same event, behaviour, or set of data using identical criteria.

1 mark for an incomplete definition (e.g. 'two observers getting similar results').
2 marks for a complete definition mentioning consistency/agreement between two or more independent observers/raters scoring the same data/behaviour.

Example answer: The consistency of scores produced by two or more independent observers (1 mark) when recording the same behaviour using the same coding scheme (1 mark).

Standardisation refers to the practice of keeping all procedures, instructions, timings, and environmental conditions completely identical and consistent for all participants in a research study, ensuring that any differences in performance are due to the independent variable and allowing exact replication.

1 mark for a basic outline (e.g. 'making everything the same for everyone').
2 marks for an elaborated outline referring to identical procedures/instructions given to all participants to ensure control or replicability.

Example answer: Keeping the experimental procedures and instructions identical for every participant (1 mark) to ensure control over extraneous variables / to allow replication (1 mark).

Opportunity sampling is a recruitment technique where researchers recruit individuals from the target population who happen to be present, accessible, and willing to participate at the specific time and location the study is being conducted.

1 mark for a partial outline (e.g. 'choosing people who are around').
2 marks for a clear, complete outline referring to selecting participants who are readily available, accessible, and willing to take part at that moment.

Example answer: Selecting participants who are present and readily available to the researcher (1 mark) at the time and place of the research (1 mark).

A naturalistic observation is an observational method where researchers watch and record participants' behaviour in their typical, unaltered real-world environment without introducing artificial controls or manipulating any variables.

1 mark for a basic outline (e.g. 'watching people in a real setting').
2 marks for a clear, detailed outline referring to observing behaviour in a real-world/natural environment without manipulation of the environment/variables.

Example answer: An observational method where behaviour is watched in the participants' normal everyday environment (1 mark) without any manipulation or intervention by the researcher (1 mark).

Informed consent requires researchers to provide potential participants with comprehensive and understandable details regarding the aims, procedures, requirements, and any potential risks of the investigation before it begins, enabling them to make an educated, voluntary decision to participate.

1 mark for a partial outline (e.g. 'getting permission from participants').
2 marks for an elaborated definition referring to providing sufficient information about the nature/risks of the study so participants can make a voluntary decision to participate.

Example answer: Providing participants with enough information about the study's procedures and aims (1 mark) so that they can make a voluntary decision about whether to participate (1 mark).

Counterbalancing is an experimental control technique used specifically with repeated measures designs to eliminate order effects (e.g., practice, boredom, or fatigue).

It works by dividing participants so that different subgroups experience the experimental conditions in different sequences (for example, Group 1 completes Condition A followed by Condition B, whereas Group 2 completes Condition B followed by Condition A, often referred to as an AB/BA design).

1 mark for identifying the purpose/context: technique used to control/reduce order effects (practice, fatigue) in a repeated measures design;
1 mark for explaining the procedure: participants are divided so that half do Condition A then B and the other half do Condition B then A (or an AB/BA structure).

An operational definition involves stating a variable (independent, dependent, or co-variable) in specific, measurable, and objective terms rather than leaving it abstract.

This ensures that researchers know exactly how the variable is being measured or manipulated (e.g. measuring memory as 'the number of words correctly recalled from a list of 20 within 60 seconds'), which allows the study to be replicated to test for reliability.

1 mark for definition: defining a variable in clear, specific, and measurable/quantifiable terms (or stating how it is manipulated/measured);
1 mark for elaboration: explaining that it allows exact replication / objective testing OR providing a clear, accurate illustrative example of operationalising a variable.

(a) A scatter graph (or scattergram/scatter plot) is the appropriate visual display because both variables (hours of social media use and sleep quality score) are continuous quantitative co-variables.

(b) The data demonstrate a negative correlation: participants with higher daily social media use (e.g., Participant E with 6.0 hours) have lower sleep quality scores (16), whereas participants with low social media use (e.g., Participant G with 1.0 hour) have higher sleep quality scores (46).

(c) Correlational research only measures the strength and direction of a relationship between co-variables and does not demonstrate cause-and-effect. Other extraneous/confounding factors (e.g. academic workload, anxiety, caffeine consumption) could be causing both poorer sleep and increased social media usage.

(a) 1 mark for identifying the correct graph type:
- Scatter graph / scattergram / scatter plot (1 mark).

(b) 1 mark for an accurate description of the result in context:
- As the number of hours of social media use increases, sleep quality score decreases / there is a negative correlation between daily social media use and sleep quality (1 mark).

(c) 1 mark for explaining why causality cannot be inferred in context:
- The study investigated a correlation / relationship between co-variables rather than cause-and-effect / there was no manipulated IV (1 mark);
- A third/uncontrolled variable (e.g., stress, caffeine, homework) might lead to both higher screen time and worse sleep (1 mark).

(a) The range measures the spread/dispersion of data by calculating the difference between the highest and lowest scores. In Elena's study, the range for emotionally charged words is 11 compared to only 4 for neutral words. This indicates greater individual variation in recall performance when words are emotionally charged, whereas participants' recall for neutral words was clustered more closely together.

(b) The mean uses every individual data value in its calculation, providing a more representative overall summary of continuous quantitative data (number of words recalled), whereas the mode merely reflects the single most frequently occurring score and ignores the actual numerical values of all other scores.

(a) 2 marks for explaining the range in context:
- 1 mark for stating that recall scores were more varied / less consistent in the emotional condition compared to the neutral condition (or vice versa);
- 1 mark for linking explicitly to the data values (e.g. range of 11 for emotional words vs 4 for neutral words).

(b) 1 mark for stating a valid reason why the mean is preferred over the mode:
- The mean utilizes all participant scores / every data value in the calculation (1 mark);
- The mode only reflects the most frequent score, which may not be central / can be unrepresentative if there is no clear mode (1 mark).

(a) The mean reaction time was shorter/faster in the binaural beats condition (320 ms) than in the silence condition (415 ms), indicating faster visual processing when listening to binaural beats.

(b) To construct an accurate bar chart:
1. Title: Must clearly state both the independent variable (auditory condition: binaural beats vs. silence) and dependent variable (mean reaction time in ms).
2. Axes: The horizontal (x) axis should be labelled with the discrete categories ('Binaural beats' and 'Silence') with separated bars (gaps between categories). The vertical (y) axis must be labelled 'Mean reaction time (milliseconds)' with an appropriate, evenly spaced numerical scale starting at 0.

(a) 1 mark for outlining the difference with context:
- Mean reaction time was faster / lower in the binaural beats condition (320 ms) than in silence (415 ms) (1 mark).

(b) 2 marks for describing the construction of the bar chart:
- 1 mark for correctly identified and labelled axes (x-axis: auditory condition / binaural beats and silence; y-axis: mean reaction time in milliseconds);
- 1 mark for appropriate graphical conventions (separated bars for distinct conditions / fully informative title referring to both IV and DV / linear scale from zero).

(a) Year 7 students exhibited a higher level of pro-social acts on average compared to Year 11 students, as evidenced by a median of 9 acts per session for Year 7 versus only 4 acts per session for Year 11 (or a mode of 8 for Year 7 versus 3 for Year 11).

(b) To clearly and accurately present categorical frequency data on a bar chart:
1. Separate bars: There must be visible spaces/gaps between the bars for Year 7 and Year 11 to indicate that year groups are distinct nominal categories (not continuous data like a histogram).
2. Axis labelling & scaling: The y-axis must be labelled with the dependent measure ('Total frequency of pro-social acts') using a standardized scale starting at 0, and the x-axis must identify the two year groups.

(a) 1 mark for explaining the difference using the mode or median with data values:
- Year 7 students displayed more pro-social acts than Year 11 students because their median was 9 compared to 4 for Year 11 (1 mark);
- Year 7 students had a higher typical frequency of pro-social acts with a mode of 8 compared to 3 for Year 11 (1 mark).

(b) 2 marks for explaining two distinct graphical features (1 mark per feature):
- Distinct gaps between bars to represent separate/discrete categories (1 mark);
- Correctly labelled y-axis (e.g. 'Total frequency of pro-social acts') with an appropriate scale starting from zero (1 mark);
- Informative title specifying both the groups (Year 7 vs Year 11) and the observed behaviour (pro-social acts) (1 mark).

Example plan:

1. Operationalisation of Variables:
- Independent Variable (IV): Background auditory condition with two levels:
(a) Instrumental music condition: listening to classical instrumental music (tempo 60–70 bpm, no vocals) played through standardised noise-cancelling headphones at 50 dB.
(b) Silence condition: wearing identical noise-cancelling headphones with active noise-cancellation enabled and no sound played.
- Dependent Variable (DV): Reading comprehension performance, operationalised as the score achieved on a 20-item multiple-choice test (1 mark per correct answer, total out of 20) based on an unfamiliar 800-word factual text about marine ecosystems.

2. Experimental Design:
- An independent measures design will be used.
- Participants will be randomly allocated to either the music condition or the silent condition (e.g. using a random number generator).
- Justification: This eliminates order effects such as practice or fatigue and prevents participants from reading the same text twice or needing two different texts that might vary in difficulty.

3. Controls and Standardisation:
- Standardised text: All participants read the exact same 800-word text presented on a computer monitor with identical font style (Arial 12pt) and screen brightness.
- Standardised timing: Exactly 10 minutes will be given to read the text, followed immediately by a 10-minute period to complete the multiple-choice comprehension test.
- Environmental controls: The study will take place in an isolated, sound-attenuated laboratory room with consistent lighting and temperature (21°C) to eliminate extraneous auditory and visual distractions.
- Standardised instructions: All participants will receive identical pre-recorded verbal instructions explaining the task before beginning.

4. Data Collection:
- Type of data: Quantitative data (discrete numerical scores from 0 to 20).
- Collection procedure: Responses on the 20-item multiple-choice test will be recorded electronically via the computer software immediately upon completion to avoid scoring bias.

- Environmental controls: The study will take place in an isolated, sound-attenuated laboratory room with consistent lighting and temperature (21°C) to eliminate extraneous auditory and visual distractions.
- Standardised instructions: All participants will receive identical pre-recorded verbal instructions explaining the task before beginning.

4. Data Collection:
- Type of data: Quantitative data (discrete numerical scores from 0 to 20).
- Collection procedure: Responses on the 20-item multiple-choice test will be recorded electronically via the computer software immediately upon completion to avoid scoring bias.

Mark according to the generic 10-mark levels of response table for Paper 2 Planning (AO2 Application):

Level 4 (8–10 marks):
• The plan is detailed, fully operationalised, and could be replicated directly.
• All required features are clearly addressed (IV and DV operationalised, experimental design explained and justified, controls/standardisation explained, data collection/type specified).
• Highly effective application of methodological principles to the specific context of background music and reading comprehension.

Level 3 (5–7 marks):
• The plan is clear and mostly operationalised, though some minor procedural details may be missing.
• Most required features are addressed appropriately.
• Good application to the scenario with appropriate psychological terminology.

Level 2 (3–4 marks):
• The plan is basic or lacks operationalisation in several key areas.
• Addresses some required features, but lacks necessary controls or clarity on measurement.
• Limited application to the scenario.

Level 1 (1–2 marks):
• The plan is muddled, incomplete, or contains major methodological flaws.
• Few required features are attempted.

Level 0 (0 marks):
• No creditable response.

Ethical issue: Participants face potential psychological distress or harm to self-esteem due to being deceived into believing they performed poorly (scoring in the lowest 5%) on a test of academic capability.

Resolution: Tarek should conduct an immediate debriefing session at the end of the procedure where he explains the true aim of the experiment, reveals that the test feedback was entirely false and standardised, and checks participants' psychological well-being before they leave.

1 mark: Identification and contextual explanation of the ethical issue (e.g. psychological harm / distress / deception linked to the false feedback).
1 mark: Appropriate, practical suggestion for how to overcome/mitigate this issue in context (e.g. debriefing explaining the deception and restoring self-esteem, or offering counseling/right to withdraw data).

Note: Do not credit generic ethical guidelines without explicit reference to the scenario.

Ethical issue: Shoppers did not give informed consent to be recorded on video, and recording them covertly infringes on their right to privacy and confidentiality in the shopping mall.

Resolution: Meera or a research assistant can approach every participant who was filmed immediately after the staged incident, explain the nature of the research during a debrief, and ask for retrospective informed consent to use their video footage, offering to delete the recording immediately if they decline.

1 mark: Identification and contextual explanation of the ethical issue (e.g. lack of informed consent / privacy / deception linked to covert filming of shoppers or staged accident).
1 mark: Appropriate, practical suggestion for how to overcome/mitigate this issue in context (e.g. immediate debriefing to obtain retrospective consent / offering to destroy footage if consent is withheld).

Note: Maximum 1 mark if the answer is purely generic and not linked to the shopping mall/filming scenario.

To use exposure and response prevention (ERP) with Saira:

1. Establish a Fear Hierarchy / Graded Exposure: The psychologist and Saira develop a graded hierarchy of contamination fears (e.g., touching a clean doorknob up to touching an unwashed public door handle).
2. In Vivo Exposure: Saira is guided to touch the feared contaminated object (e.g., placing her hands on the doorknob) to evoke anxiety.
3. Response Prevention: Saira is actively prevented from engaging in her compulsive safety ritual (washing her hands with hot water/antiseptic soap) for a specified duration.
4. Habituation: Over repeated prolonged exposures without performing the compulsion, Saira learns that her anticipated catastrophic harm does not occur, allowing her anxiety to extinguish naturally.

Award marks based on accurate understanding and application of ERP to Saira's OCD:
- 1 mark for identifying/describing exposure to the feared stimulus (e.g., touching doorknobs/contaminated surfaces);
- 1 mark for identifying/describing response prevention (e.g., preventing/delaying handwashing with antiseptic soap/hot water);
- 1 mark for explaining the psychological mechanism/outcome applied to Saira (e.g., habituation/extinction of anxiety, breaking the obsession-compulsion reinforcement loop).

Note: Maximum 2 marks if there is no direct contextual link to Saira's specific symptoms (contamination/handwashing/doorknobs).

Lucas could apply psychological research on menu design in the following ways:

1. Gaze Motion and Eye-Tracking ('Sweet Spot'): Research shows that diners' eyes typically land first on the top-right corner of a two-page menu (or the centre/top of a single-page menu). Lucas can place his high-profit artisan desserts in this visual focal area to maximise immediate visual attention.
2. Primacy and Recency Effects: Information presented at the very beginning (primacy) or very end (recency) of a menu list is recalled best. Lucas can list his signature artisan desserts at the top or bottom of the menu page/section.
3. Sensory / Vivid Food Descriptions: Adding evocative, vivid descriptive adjectives (e.g., 'warm molten Belgian fudge', 'crisp hand-caramelised crust') stimulates mental imagery and sensory expectations, increasing perceived value and willingness to pay.

Award marks for suggesting valid menu design techniques applied to Lucas's café:
- 1 mark for identifying a valid menu design principle (e.g., gaze motion / sweet spot, primacy/recency, vivid/sensory food descriptors, font/visual boxing);
- 1 mark for explaining how the principle works psychologically (e.g., guiding visual fixations, enhancing memory recall, increasing perceived value/hedonic expectation);
- 1 mark for explicit contextual application to Lucas's café/artisan desserts (e.g., placing high-profit desserts at top-right or using sensory labels like 'velvety Belgian mousse').

Note: Maximum 2 marks if no explicit link to Lucas's scenario (café/high-profit artisan desserts) is made.

Tariq could use behavioural interventions to improve adherence to preventative asthma inhalers by:

1. Prompts / Cues: Setting up automated text message (SMS) or mobile notifications scheduled at specific times of day (e.g., morning and evening) to remind patients to use their inhaler.
2. Customised Regimens / Habit Chaining: Advising patients to anchor taking the inhaler to an existing daily behavioural routine (e.g., brushing their teeth in the morning/evening) so the established habit acts as an environmental prompt.
3. Visual Cues / Smart Packaging: Providing inhalers fitted with electronic dose counters, smart caps, or visual chart logs that provide clear visual feedback showing whether the daily dose has already been taken, eliminating unintentional forgetting.

Award marks for suggesting and explaining behavioural interventions to improve adherence in Tariq's pharmacy:
- 1 mark for identifying a relevant behavioural technique (e.g., automated digital prompts/SMS, stimulus control/habit pairing, customised dosing aids/dose-tracking caps);
- 1 mark for explaining how the behavioural mechanism reduces non-adherence (e.g., serves as an external discriminative stimulus, reduces cognitive load/forgetfulness, provides immediate feedback);
- 1 mark for explicit contextual application to Tariq's asthma inhaler scenario (e.g., pairing morning/evening inhaler puff with tooth brushing or text reminder).

Note: Maximum 2 marks if there is no explicit contextual link to asthma inhalers / preventative daily routine.

Elena can apply Locke and Latham's goal-setting theory by:

1. Setting Specific and Challenging Goals (SMART): Instead of vague instructions like 'work faster', Elena should establish specific, quantifiable, and challenging targets (e.g., 'complete and debug Module A within 10 working days'). Specific and difficult goals focus attention and increase effort.
2. Securing Goal Commitment: Elena should involve the software developers in setting these goals through collaborative sprint planning, ensuring developers accept and feel personal ownership over their coding targets.
3. Providing Regular Feedback: Elena should implement brief daily stand-up meetings to provide progress feedback, allowing developers to assess their performance relative to the goal and adjust their strategies accordingly.

Award marks for applying Locke and Latham's goal-setting theory to Elena's software team:
- 1 mark for identifying a core principle of goal-setting theory (e.g., goal specificity/difficulty, goal commitment/participation, regular feedback/clarity);
- 1 mark for explaining how this principle increases motivation/performance (e.g., channels effort, directs attention, increases persistence, enables self-regulation);
- 1 mark for explicit contextualisation to Elena's software development team (e.g., setting a specific target of debugging code modules before sprint deadlines or holding daily feedback check-ins).

Note: Maximum 2 marks if no direct link to Elena's software team / coding deadlines is provided.

Operant conditioning explains the maintenance of compulsive behaviours via negative reinforcement:
1. An intrusive thought or obsession creates high levels of anxiety and distress.
2. Performing the compulsive act (e.g., excessive hand-washing or checking) reduces or removes this unpleasant emotional state.
3. Because the behaviour successfully terminates the unpleasant state (negative reinforcement), the compulsion is strengthened and repeated whenever the obsessive thought recurs.

Award 1 mark for identifying negative reinforcement / anxiety reduction as the mechanism.
Award 1 mark for elaboration explaining that performing the compulsion removes the unpleasant feeling/anxiety caused by the obsession, increasing the likelihood of the behaviour being repeated.

Example 2-mark answer:
Compulsions are maintained through negative reinforcement (1 mark). When a person performs the compulsive ritual, it removes or reduces the distress/anxiety caused by the obsession, strengthening the behaviour so they repeat it in future situations (1 mark).

The anchoring heuristic refers to a mental shortcut in decision-making:
1. A person establishes a reference point based on the initial piece of information received (the anchor).
2. Subsequent judgements, price evaluations, or quantity estimates are disproportionately adjusted around that starting number (e.g., an item marked down from an inflated 'original price' seems like a bargain because the original price anchored the consumer's perception of value).

Award 1 mark for defining/identifying that the consumer relies heavily on the initial piece of information (the anchor) received.
Award 1 mark for elaboration/contextualisation explaining how subsequent judgements/estimates/purchasing decisions are adjusted relative to this initial reference point (or providing an accurate consumer example).

Example 2-mark answer:
The anchoring heuristic occurs when consumers rely too heavily on the first piece of information they see when making a judgement (1 mark). For example, seeing a high 'original price' serves as an anchor that makes the discounted sale price seem like much better value (1 mark).

Weaknesses of biochemical tests (blood/urine samples) in measuring adherence include:
- Temporal limitation: They only show presence of the drug or metabolite at the exact time of testing, meaning a non-adherent patient who takes their medication immediately prior to the clinic visit ('white-coat compliance') will appear fully adherent.
- Metabolic individual differences: Rates of absorption and metabolism vary between individuals, which can skew concentration readings.
- Invasiveness: Taking blood samples can cause physical discomfort and distress, reducing patient willingness to participate.

Award 1 mark for identifying an appropriate weakness (e.g. only measures recent intake / invasive / individual metabolic variations / cost and lab requirements).
Award 1 mark for explaining why this is a limitation in the context of assessing patient adherence.

Example 2-mark answer:
Biochemical tests only provide a snapshot of recent drug ingestion (1 mark). This means patients might only take their medication just before the test to appear adherent, masking habitual non-adherence over the long term (1 mark).

Within Vroom's VIE (Valence, Instrumentality, Expectancy) theory:
- Expectancy is the subjective probability perceived by an employee that increasing effort (
E
) will directly result in achieving the desired level of performance (
P
), often referred to as the E → P link.
- It ranges on a scale from 0 (no belief that effort leads to performance) to 1 (complete certainty that effort leads to performance), influenced by self-efficacy, resources, and training.

Award 1 mark for stating that expectancy is the belief/perception that effort leads to performance (the Effort → Performance link).
Award 1 mark for elaboration (e.g. mentioning subjective probability from 0 to 1 / role of resources, skills, or self-confidence in shaping this belief).

Example 2-mark answer:
Expectancy refers to an employee's belief that their effort will result in successful performance (1 mark). It is a perceived probability (ranging from 0 to 1) that working harder will actually enable them to achieve the required goal (1 mark).

Maudsley Obsessive-Compulsive Inventory (MOCI):
• Developed by Hodgson and Rachman (1977) as a quick self-report assessment.
• Comprises 30 forced-choice statements with a True/False response format.
• Takes approximately 4–5 minutes to complete.
• Yields an overall score (out of 30) indicating obsessive-compulsive severity.
• Assesses four distinct subscales/dimensions: Checking, Washing/Cleaning, Slowness, and Doubting.



Yale-Brown Obsessive Compulsive Scale (Y-BOCS):
• Developed by Goodman et al. (1989) as a semi-structured clinician-administered interview.
• Evaluates the presence and severity of symptoms occurring during the previous week.
• Begins with a broad Symptom Checklist categorising various types of obsessions and compulsions.
• Followed by a core 10-item severity scale: 5 items measuring obsessions and 5 items measuring compulsions.
• Each item is rated on a 5-point Likert scale (0 = None/No symptoms to 4 = Extreme).
• Assesses five distinct severity dimensions for both obsessions and compulsions: time spent, interference in functioning, distress caused, resistance attempted, and degree of control.
• Total severity score ranges from 0 to 40, where higher scores indicate greater clinical severity.

Generic marking criteria for Paper 3 AO1 6-mark description questions:

Level 3 (5–6 marks):
• Description is accurate, detailed, and clear.
• Demonstrates a thorough and balanced understanding of both measures (MOCI and Y-BOCS).
• Relevant psychological terminology is used accurately and effectively.

Level 2 (3–4 marks):
• Description is mostly accurate and relevant with some detail.
• Demonstrates adequate understanding of both measures, or detailed understanding of one measure only.
• Psychological terminology is used adequately.

Level 1 (1–2 marks):
• Description is basic, brief, or superficial with limited accuracy/detail.
• Demonstrates limited understanding of the measures.
• Minimal or inaccurate use of psychological terminology.

Level 0 (0 marks):
• No creditable content.

A comprehensive evaluative response should address multiple theoretical explanations of depression alongside the named debate:

1. Named Issue — Reductionism versus Holism:
- Biochemical and genetic explanations (e.g. Oruč et al., monoamine hypothesis) represent biological reductionism. They isolate complex affective states down to specific genetic polymorphisms (such as 5-HTT alleles) or synaptic depletion of serotonin, norepinephrine, and dopamine. A major strength of reductionism is that it facilitates scientific testing and allows pharmacological interventions (SSRIs, MAOIs) to be developed. However, biological reductionism fails to account for psychosocial stressors, life events, and cognitive appraisal mechanisms.
- Beck's cognitive theory and Abramson/Seligman's learned helplessness/attributional models adopt a more holistic stance by integrating internal thought processes (schemas, negative cognitive triad, internal/stable/global attributions) with environmental interaction and learning history. However, they can still be viewed as cognitive reductionism if they overlook underlying neurochemical predispositions.

2. Nature versus Nurture / Determinism:
- Genetic and biochemical explanations emphasize nature and biological determinism, implying that individuals lack agency over affective states. In contrast, cognitive explanations allow for free will and personal empowerment through cognitive restructuring and Ellis's REBT.

3. Methodological Evidence & Validity:
- Twin, family, and association studies (e.g. Oruč et al., 1997) demonstrate moderate concordance rates, indicating that biology alone is insufficient and supporting a diathesis-stress interaction.
- Cognitive models often suffer from correlational designs (difficult to determine whether cognitive distortions cause depression or are merely symptoms of the disorder).

4. Application and Practical Usefulness:
- Biological explanations provide targeted medical treatments (antidepressants) which are fast-acting, whereas cognitive models provide long-lasting coping mechanisms with lower relapse rates (CBT).

Generic Level Descriptors (Table B - AO3 Evaluation, 10 marks):

Level 4 (8–10 marks):
- Evaluation is comprehensive, insightful, and demonstrates thorough psychological understanding.
- Discussion of the named issue (reductionism vs holism) is thoroughly integrated, balanced, and clearly applied to explanations of depression.
- Clear structure, effective psychological terminology, and well-sustained argument throughout.

Level 3 (5–7 marks):
- Evaluation is good with appropriate points made (strengths/weaknesses/debates).
- Discussion of the named issue is present and relevant, though it may lack complete depth or balance.
- Psychological terminology is mostly used accurately.

Level 2 (3–4 marks):
- Evaluation is limited or descriptive of evaluation points.
- Discussion of the named issue may be absent, brief, or superficial (Note: Responses omitting the named issue cannot score above Level 2 / max 4 marks).

Level 1 (1–2 marks):
- Minimal evaluative content; points are unsubstantiated or poorly related to the question.

Level 0 (0 marks):
- No creditable content.

An effective evaluative answer should systematically analyse theories of job satisfaction while directly embedding the individual versus situational debate:

1. Named Issue — Individual versus Situational Explanations:
- Situational focus: Both Herzberg's two-factor theory and Hackman and Oldham's job characteristics theory heavily emphasise situational factors. Herzberg identifies extrinsic hygiene factors (company policy, salary, physical working conditions) and intrinsic motivators (advancement, responsibility, nature of the work) situated within the organisational structure. Hackman and Oldham identify five core job dimensions (skill variety, task identity, task significance, autonomy, feedback) that must be designed into the workplace environment to foster critical psychological states.
- Individual focus: Hackman and Oldham explicitly integrate individual differences via 'Growth Need Strength' (GNS) and knowledge/skill moderators. An employee with low GNS may experience stress rather than satisfaction when given high autonomy and task complexity. In contrast, Herzberg's model assumes universal applicability across all employees, neglecting individual variations in what individuals find satisfying or dissatisfying.

2. Methodological Strengths and Weaknesses:
- Herzberg's critical incident method relies on retrospective self-reports, which are prone to social desirability and self-serving bias (individuals naturally attribute positive outcomes to themselves/motivators and negative outcomes to external factors/hygiene).
- Hackman and Oldham developed the Job Diagnostic Survey (JDS), which allows quantitative psychometric calculation of the Motivating Potential Score (MPS). This enables objective comparison across job roles, though self-report rating scales can be subject to response sets.

3. Practical Application to Organisations:
- Both models have high application to everyday life by informing job redesign strategies: Herzberg inspired job enrichment, whereas Hackman and Oldham provide specific architectural guidance for job enrichment, rotation, and autonomous work groups.

Generic Level Descriptors (Table B - AO3 Evaluation, 10 marks):

Level 4 (8–10 marks):
- Evaluation is balanced, nuanced, and demonstrates thorough psychological knowledge of work satisfaction theories.
- Discussion of the named issue (individual versus situational explanations) is explicitly addressed, fully developed, and thoughtfully applied to both Herzberg and Hackman & Oldham.
- Writing is coherent with fluent use of specialist psychological vocabulary.

Level 3 (5–7 marks):
- Evaluation shows good understanding with a range of evaluative points (e.g. practical utility, psychometric testing, self-report limitations).
- The named issue is discussed and applied, though one theory may be treated more thoroughly than the other.
- Psychological terminology is generally accurate.

Level 2 (3–4 marks):
- Evaluation is brief, heavily descriptive, or lacks depth.
- Named issue may be omitted or treated as a superficial mention (Note: Max 4 marks if named issue is omitted).

Level 1 (1–2 marks):
- Fragmented or basic comments with little relevance to evaluation.

Level 0 (0 marks):
- No creditable content.

(a) Lovell et al. (2006) compared two modalities of delivering CBT with exposure and response prevention (ERP) over 10 weeks:
- Face-to-face group: Participants attended 10 weekly individual sessions held in person at a clinic, with each session lasting approximately 60 minutes.
- Telephone group: Participants attended 1 initial face-to-face session, followed by 8 weekly telephone sessions of 30 minutes each, and completed 1 final face-to-face session at week 10. Both groups were set standard homework tasks between sessions.

(b) Methodological strength:
- High standardisation / control: Both groups received the same manualised CBT and ERP content delivered by the same experienced therapists, and assessments (e.g. Y-BOCS scores) were administered by independent evaluators blind to condition. This minimised experimenter bias and ensured high internal validity.

(a) 1 mark for basic outline of the two treatment groups (e.g. one in person/clinic, one over phone).
1 mark for detail/elaboration regarding session structure (e.g. 10 weekly 1-hour face-to-face sessions vs 1 initial face-to-face + 8 telephone sessions [30 mins] + 1 final face-to-face session).

(b) 1 mark for identifying an appropriate methodological strength (e.g. standardisation of treatment manual / blind independent raters / randomised allocation).
1 mark for context-linked elaboration/justification showing how this strength enhances reliability or validity in the context of OCD treatment.

(a) Becker et al. (2011) manipulated package shape by creating yoghurt containers that were either distinctly angular (sharp corners, straight edges) or rounded (smooth, curved contours). The volume of the yoghurt, brand labelling, and actual flavour formulations were kept identical across conditions to isolate the effect of visual package geometry on perceived taste attributes (such as sweetness and sourness).

(b) Weakness in ecological validity:
- Artificial laboratory setting: Consumers evaluated yoghurt samples in a test setting focusing intensely on taste ratings immediately after seeing single package prototypes. In everyday life, food purchases involve dynamic shopping environments with background clutter, varying price points, prior brand loyalty, and consuming food in meals rather than rating single bites, reducing generalisability to real-world purchasing behaviour.

(a) 1 mark for identifying the independent variable manipulation (angular vs rounded/curved packaging shapes).
1 mark for contextual elaboration (e.g. keeping content/volume/yoghurt type identical to test sensory/taste perceptions).

(b) 1 mark for identifying a valid ecological validity weakness (e.g. artificial laboratory tasting task / lack of realistic shopping context).
1 mark for contextualised explanation showing how this limits generalisability to real consumer eating/shopping behaviour.

(a) In Bridge et al. (1988), participants in the relaxation plus imagery condition:
- Met with a therapist who taught them deep muscle relaxation techniques alongside guided visual imagery.
- Were provided with an audio recording containing guided relaxation and imagery instructions (picturing a calm, pleasant location such as a beach or countryside).
- Were asked to listen to the tape and practise the exercises daily at home for 15 minutes throughout their six-week radiotherapy treatment.

(b) Strength of standardised self-report scales:
- Objective and comparable measurement: Using validated psychometric scales (like the Leeds General Scales for depression and anxiety) provides uniform, quantitative scores. This ensures that mood changes over the course of radiotherapy can be measured objectively, allowing reliable comparisons between baseline, interim, and post-intervention scores without assessor subjectivity.

(a) 1 mark for basic outline of the intervention (relaxation techniques + guided mental imagery / peaceful scene).
1 mark for procedural detail (e.g. provision of an audio tape / instruction to practise daily for 15 minutes during radiotherapy course).

(b) 1 mark for identifying a methodological strength of standardised scales (e.g. high reliability / produces quantitative data / facilitates direct statistical comparison).
1 mark for contextual link to measuring psychological adjustment/mood states (anxiety/depression) in cancer patients.

(a) In Experiment 1, Claypoole and Szalma (2019) manipulated EPM across three distinct levels of surveillance:
- Control group: Completed the sustained attention task without any monitoring equipment or surveillance instructions.
- Video monitoring group: Completed the task while an active webcam visibly pointed at them, having been told their facial expressions and behaviour were being recorded and evaluated.
- Automated/computer monitoring group: Completed the task with on-screen electronic monitoring tracking and auditing their exact response times and error rates.

(b) Methodological weakness:
- Low mundane realism / task artificiality: The visual vigilance task required detecting minute stimulus alterations on a screen for a short continuous duration in a lab. Real work tasks involve diverse responsibilities, interruptions, intrinsic motivation, and interpersonal interactions over several hours or months; hence, findings regarding stress and vigilance decrements under EPM may not fully generalise to real organisational environments.

(a) 1 mark for identifying the conditions (e.g. no monitoring vs video/webcam monitoring vs computer-based tracking).
1 mark for detail/elaboration on how participants were informed/set up with the monitoring apparatus.

(b) 1 mark for identifying an appropriate weakness (e.g. lack of mundane realism / artificial laboratory vigilance task).
1 mark for contextual elaboration explaining why this limits generalisation to actual organizational work settings.

1. Alternative Methodology Suggestion (AO2):
- The psychologist could use a structured behavioural observation, such as a Behavioural Avoidance Test (BAT) in a clinic or home setting.
- Participants are presented with a standardised OCD trigger (e.g., touching an unsterilised door handle or messy surface).
- Observers record operationalised behavioural metrics pre- and post-therapy, such as latency to initiate a ritual, total duration of compulsive cleaning/checking behaviours, or frequency of avoidance behaviours within a set 15-minute period.
- Standardisation: using two independent trained observers recording tally counts to ensure inter-observer reliability.

2. Methodological Evaluation (AO3):
- Strength: High construct validity / objectivity.
- In self-report scales (like Y-BOCS), patients may show demand characteristics, social desirability bias, or retrospective recall inaccuracies by under-reporting or over-reporting compulsive acts to please the therapist.
- Direct behavioural observation yields objective, quantifiable data on actual compulsive acts performed, giving a more accurate representation of treatment efficacy.

AO2: Suggestion of alternative methodology (2 marks):
- 2 marks: Clear, practical suggestion of an observational method with operationalised behavioural categories/metrics (e.g. timing rituals, counting compulsive checks) in a defined context (pre- and post-treatment).
- 1 mark: Vague or generic observational suggestion lacking operationalisation or clear contextual link to ERP/OCD.

AO3: Evaluation of alternative methodology (1.5 marks):
- 1.5 marks: Detailed evaluation of a methodological strength (e.g. increased objectivity, avoidance of demand characteristics/social desirability bias) explicitly linked to assessing OCD treatment outcomes.
- 0.5–1 mark: Generic strength identified with incomplete justification or limited contextualisation.

1. Alternative Methodology Suggestion (AO2):
- Design a field experiment in an authentic supermarket environment.
- Independent Variable (IV): Ambient scent condition (e.g., Condition 1 = uplifting citrus scent diffused through HVAC systems; Condition 2 = no ambient scent/control), alternated on matched days/weeks.
- Dependent Variable (DV): Total money spent per customer, measured objectively using electronic point-of-sale (EPOS) till receipt records.
- Controls: Keeping store layout, lighting, and background music constant across both scent conditions.

2. Methodological Evaluation (AO3):
- Limitation: Reduced control over confounding/extraneous variables (low internal validity).
- In a real supermarket, uncontrollable factors such as unannounced product price discounts, bad weather reducing customer footfall, seasonal variations, or differing demographic profiles of shoppers at different times can influence spending independently of the ambient scent, making it difficult to establish direct cause-and-effect.

AO2: Suggestion of alternative methodology (2 marks):
- 2 marks: Clear, operationalised field experiment design including explicit manipulation of the IV (scent condition in a real store) and measurement of the DV (actual spending/receipt totals).
- 1 mark: Outline of a field study that is brief, incomplete, or lacks clear operationalisation of variables.

AO3: Evaluation of alternative methodology (1.5 marks):
- 1.5 marks: Thorough explanation of a methodological limitation (e.g. extraneous variables, lack of standardised control, lower internal validity) directly applied to the supermarket spending context.
- 0.5–1 mark: Generic evaluation point with minimal application to consumer behaviour.

1. Alternative Methodology Suggestion (AO2):
- The researcher could use a biochemical analysis, such as collecting urine samples or blood plasma samples from patients during the prescribed 10-day antibiotic course (e.g., at day 3, day 6, and day 10).
- Samples are assayed in a laboratory for chemical traces/metabolites of the specific antibiotic compound (or an inert metabolic marker/tracer pill co-administered with the antibiotic).
- Adherence is operationalised as the detectable concentration of the drug metabolite matching therapeutic target thresholds.

2. Methodological Evaluation (AO3):
- Strength: High measurement validity and complete objectivity.
- Self-report interviews frequently suffer from social desirability bias and memory failure, as patients often exaggerate their adherence to avoid disapproval from healthcare providers.
- Biochemical markers provide unambiguous, empirical proof of ingestion that cannot be falsified by the participant, directly reflecting true physiological compliance.

AO2: Suggestion of alternative methodology (2 marks):
- 2 marks: Clear description of a practical biochemical/physiological measurement (e.g. blood/urine assay, chemical marker), including timing and operationalisation of adherence.
- 1 mark: Basic suggestion of a biological test lacking procedural detail or operational clarity.

AO3: Evaluation of alternative methodology (1.5 marks):
- 1.5 marks: Well-developed evaluation of a methodological strength (e.g. objectivity, elimination of social desirability/demand characteristics, higher construct validity) applied directly to antibiotic adherence.
- 0.5–1 mark: Superficial strength with limited justification or context.

1. Alternative Methodology Suggestion (AO2):
- The psychologist implements a longitudinal study over 6 to 12 months comparing workers trained in setting SMART goals against a control group receiving standard instructions.
- Objective performance metric: automated production logs recording the number of defect-free units assembled per hour, or error rates per shift, tracked weekly across the entire study duration.
- Baseline performance is measured before goal implementation and tracked repeatedly at 1-month, 3-month, and 6-month intervals.

2. Methodological Evaluation (AO3):
- Limitation: High risk of participant attrition (sample drop-out) and history/maturation effects.
- Over several months, skilled employees may leave the company or transfer departments, biasing the remaining sample. Furthermore, external events (e.g., changes in factory machinery, shift scheduling, or seasonal fatigue) may confound productivity trends, making it hard to isolate the effect of SMART goal setting over time.

AO2: Suggestion of alternative methodology (2 marks):
- 2 marks: Clear, operationalised longitudinal design using an objective performance metric (e.g. units produced, error tallies) tracked over multiple intervals with clear comparison groups.
- 1 mark: Incomplete longitudinal plan or vague performance metric.

AO3: Evaluation of alternative methodology (1.5 marks):
- 1.5 marks: Comprehensive evaluation of a methodological limitation (e.g. participant attrition, history/maturation effects, time-consuming nature) directly tied to assessing employee performance over time.
- 0.5–1 mark: Generic evaluation point lacking application to the workplace scenario.

Sample Model Plan:

1. Aim and Hypotheses:
• Aim: To investigate whether the presence of an ambient citrus scent in a high-street clothing store significantly increases the time (in minutes) spent browsing by customers compared to a no-scent control condition.
• Directional (one-tailed) alternative hypothesis: Shoppers in the citrus-scented condition will spend significantly more time browsing in the store (measured in minutes and seconds from entry to exit) than shoppers in the un-scented control condition.
• Null hypothesis: There will be no significant difference in the time spent browsing in the store between the citrus-scented condition and the un-scented control condition, and any observed difference will be due to chance.

2. Sample and Sampling Technique:
• Sample: 80 adult shoppers (aged 18–65, 40 per condition; balanced for gender where possible) visiting a medium-sized urban clothing store.
• Sampling Technique: Opportunity sampling, selecting every third customer who enters the store alone during the testing periods until 40 participants per condition are reached. Solitary shoppers are chosen to avoid social influence on browsing time.

3. Experimental Design and Controls:
• Independent Variable (IV): Scent condition with two levels — Level 1: Ambient citrus scent dispersed via four hidden electronic cold-air diffusers at standard intervals; Level 2: Control condition with identical diffusers operating without scent (clean ambient air).
• Design: Independent measures design. To avoid order effects and scent lingering, testing occurs on alternate weekdays (e.g. scented on Tuesday/Thursday, unscented on Wednesday/Friday) at identical time slots (14:00–17:00).
• Controls: Background music playlist, store lighting (500 lux), indoor temperature (21°C), store layout, and promotional sale signage remain constant across all testing periods.

4. Measurement of DV and Data Analysis:
• Dependent Variable (DV): Browsing time, operationalised as total time spent in the store from the moment the participant steps across the entrance threshold until they step across the checkout/exit threshold.
• Data Collection: Measured covertly by two trained observers positioned at unobtrusive vantage points using synchronised digital stopwatches. Inter-rater reliability will be assessed using a preliminary sample to ensure stopwatch timing consistency.
• Descriptive Statistics: The mean and median browsing times (in minutes) will be calculated for both the scented and unscented conditions. Measures of spread will be calculated using the standard deviation and range. A bar chart will be plotted comparing the mean browsing duration between the two conditions.

5. Ethical Considerations:
• Protection from Harm: The citrus scent used will be hypoallergenic and dispersed at low concentrations below allergen threshold levels to prevent respiratory irritation or allergic reactions.
• Privacy and Confidentiality: No names, photos, or identifying video footage will be recorded; participants are assigned numerical identifiers (e.g. Participant 1–80).
• Debriefing and Consent: A prominent, clearly visible debriefing poster will be placed near the store exit explaining that an environmental psychology study was taking place, providing contact details for the lead researcher, and allowing shoppers to request the withdrawal of their timed data.

Level-of-Response Assessment Grid (Table A — AO2 Application / Planning):

• Level 4 (8–10 marks): The response is a well-planned, practical, and fully operationalised study. All required features are addressed in clear, appropriate detail. Terminology is accurate throughout. A researcher could replicate the study directly from the description provided.
• Level 3 (5–7 marks): The response is a mostly planned study with good detail. Most required features are addressed with reasonable operationalisation. Methodological decisions are mostly appropriate, though some details may require minor clarification for replication.
• Level 2 (3–4 marks): The response is a basic plan with limited detail and weak operationalisation. Only some required features are addressed or the method chosen has serious design flaws.
• Level 1 (1–2 marks): The response shows minimal planning with little relevant detail. Fails to address the majority of the required bullet points.
• Level 0 (0 marks): No creditable content.

Indicative Content Breakdown:

- Clear statement of aim relating ambient scent to retail browsing time.
- Fully operationalised directional/non-directional alternative hypothesis and corresponding null hypothesis.

2. Sample & Sampling (1–2 marks):
- Appropriate sample size and demographic description (e.g., 60–100 retail shoppers).
- Explicit sampling technique identified (e.g., opportunity or systematic sampling) and applied in context.

3. Design & Controls (2–3 marks):
- Correctly identified IV (citrus scent vs no scent) and design (independent measures).

4. DV Measurement & Descriptive Statistics (2–3 marks):
- Operationalisation of DV (exact duration from store entry to exit recorded via stopwatch/timing).
- Named descriptive statistics: measures of central tendency (mean/median), measures of spread (standard deviation/range), and graphical representation (bar chart).

5. Ethics (1 mark):
- Specific ethical safeguards relevant to retail field experiments (e.g. non-toxic/hypoallergenic scent, debrief signage at exit, right to withdraw, data anonymity).

Methodological Defense (RCT vs Case Series):
An RCT with random allocation ensures participant variables (e.g. baseline symptom severity, duration of OCD) are evenly distributed across conditions, preventing selection bias. The double-blind control design controls for demand characteristics and practitioner/experimenter expectancy effects, which an open case series cannot prevent. This allows the psychologist to establish a direct cause-and-effect relationship between the specific intervention (ERP vs SSRIs) and the reduction in OCD symptoms (e.g. measured via Y-BOCS scores).

Theoretical Framework Justification (Cognitive-Behavioural Model):
The cognitive-behavioural framework posits that obsessions create anxiety due to catastrophic misinterpretations (thinking errors), and compulsions are operantly conditioned behaviours maintained through negative reinforcement (temporary reduction of anxiety). ERP directly targets this mechanism: exposure to the obsession triggers anxiety, while prevention of the compulsive response enables habituation and extinction to occur, disconfirming the patient's irrational belief that harm will occur without the ritual.

• Methodological defense (2 marks):
- 1 mark for explaining control of participant variables/selection bias via randomisation OR eliminating researcher bias/placebo effects via double-blind controls.
- 1 mark for linking methodological rigor directly to internal validity / establishing causal efficacy in OCD treatment outcome comparison (compared to the lack of generalisability/confounds in a case series).
• Theoretical framework justification (1.5 marks):
- 1 mark for identifying how the cognitive-behavioural model explains OCD maintenance (e.g. negative reinforcement, failure of habituation due to neutralizing rituals).
- 0.5 mark for explicitly linking the theory to the functional mechanism of ERP (exposure breaks the conditioned fear response / prevents avoidance to allow cognitive disconfirmation).

Theoretical Framework Justification (PAD Model):
Mehrabian and Russell's PAD model posits that physical environmental stimuli (such as ambient scent and jazz music) alter internal emotional states along three dimensions: Pleasure, Arousal, and Dominance. These emotional states directly mediate subsequent consumer behaviour, resulting in either 'approach' behaviours (e.g. browsing longer, spending more money) or 'avoidance' behaviours (e.g. leaving the boutique). Using this framework enables the researchers to measure the underlying emotional mechanism explaining why sensory modifications alter purchasing patterns, rather than merely recording superficial behavioural outcomes.

Methodological Defense (Field Experiment vs Lab Simulation):
A field experiment is conducted in the natural boutique setting where consumers use their own actual financial resources. This achieves high ecological validity and mundane realism. In contrast, laboratory simulations or virtual stores produce artificial demand characteristics where participants make hypothetical purchase decisions without real economic consequences, distorting genuine spending behaviour.

• Theoretical framework justification (1.5 marks):
- 1 mark for outlining the core components of the PAD model (emotional states of Pleasure, Arousal, Dominance leading to approach/avoidance behaviours).
- 0.5 mark for linking PAD to the scenario (mediating how music/scent drive shopping duration and monetary spending).
• Methodological defense (2 marks):
- 1 mark for identifying high ecological validity / mundane realism in the actual boutique setting.
- 1 mark for contrasting with the weakness of lab simulations (hypothetical purchasing, demand characteristics, lack of real financial commitment).

Methodological Defense (Objective/Biochemical vs Self-Report):
Relying solely on self-reports is vulnerable to social desirability bias, where patients over-report compliance to please healthcare practitioners, as well as recall inaccuracies (especially among older populations). Biochemical assays (urine metabolite tests) provide objective, valid physiological confirmation of whether the drug was ingested and metabolised. Electronic pill dispensers add objective time-stamped behavioural data (tracking adherence schedule and dose intervals), ensuring measurement validity that cannot be faked or forgotten.

Theoretical Framework Justification (Health Belief Model):
Becker's Health Belief Model (HBM) explains adherence as a balance of cognitive evaluations: perceived susceptibility to hypertension complications (e.g. strokes), perceived severity of the illness, perceived benefits of the medication, and perceived barriers (e.g. cost, side effects, forgetting). Applying the HBM allows the psychologist to identify which specific dimension (e.g. lack of 'cues to action' or high 'perceived barriers') predicts non-adherence, enabling the intervention to target the exact cognitive determinant.

• Methodological defense (2 marks):
- 1 mark for explaining the limitations of self-report (social desirability bias, recall decay/forgetting in older adults).
- 1 mark for defending the validity of biochemical assays and electronic dispensers (objective quantitative confirmation of ingestion and timing).
• Theoretical framework justification (1.5 marks):
- 1 mark for identifying relevant HBM dimensions (perceived threat/susceptibility, perceived benefits vs barriers, cues to action).
- 0.5 mark for contextual application to understanding/predicting hypertension medication adherence.

Theoretical Framework Justification (Goal-Setting vs Maslow):
Latham and Locke's Goal-Setting Theory provides direct, actionable mechanisms for task motivation by focusing on specific, challenging, yet attainable goals (SMART principles) accompanied by direct feedback. This creates immediate cognitive direction, effort regulation, and task persistence for logistics operations. In contrast, Maslow's Hierarchy of Needs is non-linear, difficult to operationalise for concrete daily work tasks, and assumes a rigid hierarchical progression that cannot easily be tailored to immediate job performance targets.

Methodological Defense (Objective Metrics vs Supervisor Ratings):
Objective productivity metrics (e.g. units processed per hour, error rates recorded automatically) provide standardised, ratio-level quantitative data with high reliability and zero observer subjectivity. In contrast, supervisor rating scales are vulnerable to subjective biases, such as halo/horns effects, central tendency bias, and interpersonal favoritism, which threaten the construct validity of the evaluation.

• Theoretical framework justification (1.5 marks):
- 1 mark for explaining the operational strengths of Latham & Locke (specificity, challenging goals, feedback directing immediate effort/persistence) contrasted with Maslow's abstract/rigid hierarchy.
- 0.5 mark for linking goal setting directly to task performance in logistics operations.
• Methodological defense (2 marks):
- 1 mark for identifying the reliability and objectivity of automated quantitative metrics (units/errors).
- 1 mark for explaining the prevention of supervisor subjectivity/rating errors (e.g. halo effect, leniency/favouritism).
