Key questions: Suitable examples — Edexcel A-Level Psychology

Key questions in Pearson Edexcel A-Level Psychology require students to apply psychological concepts, theories, and empirical research to contemporary societal issues across all core approaches. High-scoring responses clearly articulate the societal relevance of the issue while maintaining a balanced, evidence-based psychological explanation.

In Pearson Edexcel A-Level Psychology, Key Questions form a compulsory component across core topics, requiring candidates to apply psychological theories, concepts, and studies to contemporary issues in society. Whether examining football hooliganism in Social Psychology, memory decline in Cognitive, violence and brain injury in Biological, or screen media effects in Learning Theories, students must demonstrate that psychology has genuine utility outside the laboratory.

Exam success hinges on achieving an equal balance between describing the real-world issue (AO1) and applying psychological explanations or interventions (AO2). High-scoring answers avoid vague generalisations by weaving specific theoretical mechanisms, key studies, and practical implications directly into their analysis of the societal challenge.

• →AO1/AO2 Balance: Equal weighting must be given to outlining the societal issue (statistics, impact on economy/well-being) and applying psychological theory.
• →Social Approach Applications: Explaining phenomena such as riot behaviour, prejudice towards minorities, or obedience to unlawful orders using Social Identity Theory, Realistic Conflict Theory, or Agency Theory.
• →Cognitive Approach Applications: Addressing eyewitness reliability or dementia care using the Multi-Store Model, Working Memory Model, or reconstructive memory.
• →Biological Approach Applications: Analysing violent offending, addiction, or neurodevelopmental disorders using brain lateralisation, neurotransmitters, or evolution.
• →Learning Approach Applications: Evaluating children's exposure to video game violence, eating disorders, or phobias using Social Learning Theory, classical conditioning, and operant conditioning.

• Setting the two accounts against each other by name, deindividuation and the elaborated social identity model, and saying what each predicts about whom a crowd will and will not attack.
• Using evidence of targeting, such as the St Pauls crowd choosing police and banks and respecting the boundary of its own area, to argue that crowd action follows a social identity rather than a loss of self.
• Turning explanation into practical advice: differentiated policing that isolates the few instead of treating a whole crowd as rioters, dialogue and liaison officers, and superordinate goals that rival groups can only achieve together.
• Naming the conditions contact must meet, equal status, cooperation, shared goals and institutional support, rather than claiming that simply mixing groups reduces prejudice.
• Defining heroism in a clause, voluntary action on behalf of others that carries real cost or risk to the actor, and distinguishing physical risk heroism from social heroism such as whistleblowing.
• Using agency theory properly, so the hero moves from the agentic state to the autonomous state, and naming the conditions from the variations that make the shift easier, a distant or less legitimate authority and above all allies who disobey first.
• Applying social impact theory with all three factors, so the drop in obedience with rebellious peers is explained by impact being divided among more targets rather than by simple imitation.
• Bringing in the limits, namely diffusion of responsibility as the group of witnesses grows and the tendency for help to be offered to in-group members, then drawing the applied conclusion that heroism can be encouraged by widening who counts as us.
• Description marks for the scale and the social cost: how many people are affected, the rising numbers as the population ages, the pressure on social care and hospital beds, and the unpaid hours given by relatives.
• Mapping the symptoms onto the memory models. The multi store model explains why immediate span can look almost normal while nothing new is retained, and the working memory model explains why following a conversation or doing two things at once breaks down, since that is central executive work.
• Using the patient evidence properly. Scoville and Milner found new long term memories could not be formed after medial temporal removal while procedural learning continued, and Schmolck and colleagues found semantic knowledge was preserved when damage stopped at the hippocampal formation and lost when it reached lateral temporal cortex.
• Applications stated as things people actually do: reminiscence work using old photographs and music, cognitive stimulation therapy, errorless learning and spaced retrieval so that mistakes are not rehearsed, external memory aids, labelled and simplified environments, and training carers to give one instruction at a time.
• Evidence for those applications and its limits. Spector and colleagues (2003) ran a randomised controlled trial of cognitive stimulation therapy and reported gains in cognitive test scores and quality of life, but such programmes support function and do not slow the underlying neurodegeneration.
• Evaluation credit for the debates this raises: reductionism in treating a person as a failing memory system, and socially sensitive research with participants whose consent must be revisited because they cannot remember giving it.
• Description marks for the issue itself: the proportion of the population affected to some degree, the consequences for attainment, self esteem and employment, and the argument about how schools identify and fund support.
• The working memory explanation set out as a mechanism. The phonological loop stores speech based material briefly and rehearses it subvocally, so a weak loop means sound sequences decay before they can be mapped onto letters, which is why blending and holding a spoken instruction both suffer.
• Evidence attached to each claim: poorer non word repetition and reduced digit span in children with reading difficulty, and the developmental digit span work showing that spans are language specific, so norms taken from English speaking samples would misjudge a child tested in another language.
• Applications made concrete: structured multisensory phonics that rehearses sound to letter mapping, short instructions given one step at a time, written prompts and memory aids that take load off the loop, extra time and text to speech software, and teacher training in spotting working memory overload rather than inattention.
• Assessment credit for competing explanations and limits. Visual and magnocellular accounts and the cerebellar deficit hypothesis explain findings the phonological account does not, dyslexia is not reducible to one component of a model, and support improves access rather than removing the difficulty.
• Issues and debates links that examiners reward: reductionism, nature and nurture in a difficulty that is partly heritable and heavily shaped by teaching, and the socially sensitive consequences of labelling a child.
• Explaining the mechanism in receptor terms rather than by analogy, that a long-acting agonist occupies opioid receptors, prevents withdrawal and blunts the euphoria of a subsequent dose.
• Citing effectiveness evidence with the outcome measure attached, since the trials judge retention in treatment and urine-verified heroin use rather than lifelong abstinence.
• Saying explicitly what drug therapy does not treat, which is cue-triggered craving, the social circumstances that maintain use, and any co-occurring mental health problem, with relapse common when the prescription stops.
• Comparing alternatives so the judgement is genuinely comparative: buprenorphine as a partial agonist, naltrexone as an antagonist that blocks rather than substitutes, and psychological work such as contingency management or cue exposure, with combined treatment outperforming medication alone.
• Evaluating the evidence base itself, that randomised trials with objective urine testing are high in internal validity but suffer selective drop-out, run for short periods, and measure outcomes that patients, clinicians and government value differently.
• Stating the evidence position accurately before reasoning from it, that twin and adoption data show a genetic contribution to variation rather than genetic determination, and that the working model is diathesis and stress.
• Naming research that makes the interaction concrete, such as heritable physical aggression alongside environmentally carried social aggression in the twin work of Brendgen et al. (2005), the maltreatment by genotype interaction reported by Caspi et al. (2002), and Raine et al. (1997), whose own conclusion was predisposition rather than destiny.
• Working through implications across several institutions rather than one: criminal responsibility and sentencing, screening and prevention, allocation of public money, and possible discrimination by employers or insurers.
• Tying the answer to the debates the specification names, particularly free will and determinism, and socially sensitive research, since findings about the biology of violence have consequences for how whole groups are treated and reported.
• Describe the issue before explaining it, because prevalence among teenage girls and the rise among boys, the typical age of onset, mortality and relapse rates and the reach of social media are all creditworthy context.
• Apply social learning precisely, with attention to an attractive model, retention of the image, reproduction through dieting and motivation supplied by the rewards the model is seen to receive, and identification explaining why a similar celebrity matters more.
• Add the conditioning strands, since weight loss is reinforced by compliments and by a sense of control, while eating repeatedly paired with guilt makes food itself a trigger for anxiety.
• Use evidence on both sides, because the Fijian findings support media influence while higher concordance in identical than in non-identical twins, and the fact that most exposed people never become ill, support a vulnerability model.
• Reach a judgement in the words of the question, for example that role models are a contributory risk factor rather than a sufficient cause.
• Frame the issue for society, giving the proportion of travellers affected, the avoidance that follows, the commercial loss to carriers and the personal cost of not being able to fly for work or family.
• Explain acquisition and maintenance separately, so association pairs the aircraft with fear while negative reinforcement of avoidance explains why the phobia persists with no new frightening experience.
• Set out what a programme would contain, with relaxation training, a hierarchy running from photographs to boarding, graded exposure, sometimes a supervised flight, and evidence that most treated people report much less fear afterwards.
• Argue the case both ways, because recovered flyers buy tickets and recommend the airline, while sessions cost money and staff time, some clients gain nothing, and the provider has an obvious interest in the result it reports.
• Widen the answer with a competing explanation such as preparedness, the idea that some fears are learned far more readily than others because they once had survival value.
• Define abnormality by more than one route, for example deviation from social norms and failure to function adequately, and show that each route leaves the threshold to local judgement.
• Name the classification systems and where they were written, the American psychiatric manual and the World Health Organization's, both largely produced in Western clinical settings, which is the basis of the imposed etic criticism.
• Use a cultural concept of distress with its actual content, such as taijin kyofusho, a Japanese social anxiety centred on fear of offending others rather than of being judged, to show that symptom patterns are locally shaped.
• Bring evidence of unequal diagnosis inside one society, such as the raised rates of schizophrenia diagnosis among African Caribbean people in Britain, and separate the candidate explanations of clinician misdiagnosis, different help seeking and genuine differences in social adversity.
• Conclude on the emic and etic distinction by arguing whether the category itself varies or only the idiom in which it is expressed.
• Separate the two claims explicitly, that working conditions can cause or worsen disorder, and that carrying a disorder changes how a person is treated at work.
• Use a named model of work strain with its mechanism, such as low decision latitude converting high demand into strain, rather than asserting that work is stressful.
• Bring clinical content to bear, for example Beck's cognitive triad explaining how repeated failure feedback at work builds a negative view of the self, or diathesis stress explaining why a vulnerable employee breaks down under sustained pressure.
• Give the applied consequence, employee assistance programmes, cognitive behavioural stress management, screening and reasonable adjustments, and say what the evidence for each does and does not show.
• Evaluate the evidence base, noting that most workplace data is self report and cross sectional, so the direction of causation between job strain and depression is hard to pin down.
• Credit for evidence on both sides, distortion demonstrated under controlled conditions set against the accuracy shown by witnesses to real crimes, rather than a one sided case.
• Naming mechanisms earns the explanation marks: post event misinformation, high arousal narrowing attention, weapon focus, delay before the first interview and the advantage people have at recognising faces from their own group.
• Credit for the applied response, including video identification parades with foils, a judicial warning to juries about confident witnesses, and the cognitive interview with its report everything, context reinstatement, change of order and change of perspective stages.
• A judgement earns the assessment marks when it is qualified, for instance that such evidence is reliable enough to use with corroboration and proper procedure but not reliable enough to convict on alone.
• Credit for naming who is affected, the wrongly convicted, victims whose real assailant is never caught, and public confidence in verdicts.
• Credit comes first for putting the question in society's terms, that a verdict is meant to rest on the evidence and research shows it also rests on the defendant's accent, appearance and the order in which the story is told.
• Name the bias and the study together: Dixon, Mahoney and Cocks (2002) for accent, Castellow, Wuensch and Moore (1990) for attractiveness, where an attractive defendant drew guilty verdicts from a little over half the mock jurors against roughly three quarters for an unattractive one, and Pennington and Hastie (1988) for story order.
• Explain the mechanism rather than listing effects, so say that jurors build a story from the evidence and fit later information to it, and that stereotypes and halo effects fill the gaps where the evidence is thin.
• Markers reward the counterargument, and Thomas's research for the Ministry of Justice put real jurors through simulated cases at Crown Courts, finding verdicts were not racially biased although many jurors misunderstood the judge's legal directions, which points to better directions rather than to no jury.
• A conclusion that weighs the alternatives, judge only trials of the kind used in Northern Ireland, or reforms such as written directions and screening for pre-trial publicity, earns the evaluative marks a list of biases cannot.
• Set the question up as a decision with named factors, which are age at entry, hours per week, the quality of the setting and the consistency of the key person, because each of those has research attached to it.
• Give evidence pointing both ways, the insecure avoidant finding from Belsky and Rovine and the raised behaviour problem scores in the American cohort against the intellectual and social gains reported in the English preschool research.
• Define quality in the terms researchers actually measured, such as adult to child ratios, staff qualifications and observed sensitivity of caregiving, rather than as a vague word.
• Reach a conclusion the evidence supports, that quality and stability predict outcomes more strongly than attendance in itself, and note that temperament and family circumstances produce individual differences.
• Frame the answer around what the child is moved from and to, since the finding concerns the length of deprivation before placement rather than the crossing of a border in itself.
• Use the age at placement result precisely, with children adopted before about six months showing substantial recovery and later placed children showing difficulties that persisted at follow up.
• Name the deprivation specific pattern reported in the later follow ups, which is disinhibited social approach, quasi autistic features, inattention and overactivity, and lower cognitive scores.
• Balance developmental evidence against cultural and ethical argument, including loss of heritage and birth language and the risk that demand from wealthy countries distorts child protection in poorer ones.
• Framing the behaviour as biological dependence plus conditioned cues plus social norms, so that an effective package has to address all three rather than one.
• Naming pharmacological support with evidence: nicotine replacement improving quit rates by roughly half to sixty per cent over placebo in pooled reviews, and varenicline outperforming it, both working by reducing withdrawal and craving.
• Naming behavioural methods and saying what they do, so aversion therapy pairs smoking with nausea or with rapid smoking to build a conditioned aversion, while contingency management pays for biochemically verified abstinence, an approach Volpp and colleagues found roughly tripled quit rates in an American workplace trial.
• Using campaign evidence rather than intuition, including the finding by Janis and Feshbach (1953) that a moderate fear appeal changed dental behaviour more than the strongest appeal did, which predicts that the most graphic warnings can trigger defensive avoidance.
• Judging effectiveness honestly, since relapse is the normal outcome, effect sizes are modest, and price rises and smoke-free legislation change the behaviour of smokers who would never attend a service.
• Bringing in the ethical line, that heavy taxation falls hardest on the poorest smokers and that targeting them raises stigma, which is the socially sensitive side of the issue.
• Setting out both positions and naming the debate, so free will and determinism on one side and the ethical issue of paternalism and social control on the other.
• Citing legislation that changed behaviour: minimum unit pricing in Scotland was followed by a fall of around seven per cent in alcohol bought for drinking at home and by a marked fall in deaths caused wholly by alcohol, and emergency admissions for heart attacks in England fell after the smoke-free law of 2007.
• Explaining nudge and libertarian paternalism with a concrete change of default, and noting that the effects are usually small but the costs are very low.
• Handling the counter-arguments properly, including regressive taxation, illicit markets, stigma, and the evidence that information campaigns on their own change little.
• Reaching a judgement that separates types of intervention, so that a ban, a price, a default and a campaign are each weighed on their own evidence rather than lumped together as interference.

• 💡This is a key question, so the answer needs the problem described as a current one, which a named recent episode of disorder supplies, as well as the theory.
• 💡Application items often give a scenario about a protest, a stadium or a police operation, so practise choosing between social identity and deindividuation for a given stem.
• 💡Keep one line on socially sensitive research, since advice about how to police crowds can be turned on legitimate protest as easily as on rioters.
• 💡Heroism is one of the board suggested key questions, so it can arrive as an extended item asking you to explain it using concepts, theories and research drawn from social psychology.
• 💡Examiners reward a figure attached to a named study, so learn one obedience percentage and one helping result well enough to quote accurately.
• 💡Free will and determinism is the natural debate to raise, because a purely situational account removes the moral credit we normally give a hero.
• 💡The two parts of a key question answer are often asked as separate items, so be able to describe the issue for society without any psychology, and then apply the psychology on demand.
• 💡Keep one checkable figure and one named therapy, since specific detail is what separates a top band description from a general one.
• 💡This answer doubles as material for questions on the usefulness of psychology and on ethics in socially sensitive research, so revise it with those uses in mind.
• 💡Be ready to describe the issue for society first without mentioning a model, because the description and the application are credited separately.
• 💡Questions phrased as how far can cognitive psychology explain this expect a judgement, so end by weighing the phonological account against alternatives rather than summarising it.
• 💡The digit span evidence used here is also a studies answer and a culture answer, which makes it the most economical study in this topic to learn thoroughly.
• 💡Effectiveness questions expect a criterion, so state by what measure and over what period you are judging before you reach a verdict.
• 💡Keep one review or trial finding you can quote, because a stated outcome measure lifts an answer above general claims that therapy sometimes works.
• 💡A conditional conclusion scores best here, for example effective for retention and harm reduction, weaker for abstinence, and stronger still when combined with psychological therapy.
• 💡Items using discuss or assess expect both sides and then a judgement, so plan implications for and against and finish with a conditional conclusion rather than a slogan.
• 💡Name the debate explicitly, because writing that this is an issue of determinism and of socially sensitive research signals the synoptic link the mark scheme is looking for.
• 💡Use one interaction study as the pivot of the answer, since it lets you reject the strong nature claim while still taking the implications seriously.
• 💡Blame is the trap here, and the examiner rewards a balanced conclusion naming other risk factors rather than a campaign against magazines.
• 💡Carry two or three precise pieces of applied evidence, because vague references to the media read identically across every script.
• 💡The same material answers a shorter question asking for one way the learning approach explains disordered eating, so practise it at both lengths.
• 💡Extended answers here expect a conclusion, so decide your position early and use the evaluation to justify it rather than to hedge.
• 💡Anchor the therapy to named research instead of general claims about exposure, because the specification expects the contemporary study to be used.
• 💡Read the command word, since assess and discuss want a weighed judgement while explain wants the mechanism, and the same knowledge is organised differently for each.
• 💡This is socially sensitive material, so examiners reward a measured conclusion and a practical implication, such as culturally trained clinicians and properly briefed interpreters, over a strong opinion.
• 💡Keep two contrasting pieces of evidence ready, one showing variation in how distress is expressed and one showing variation in diagnosis rates, so you can argue both sides under assess.
• 💡Tie the answer back to classification and diagnosis, because your reliability and validity evidence earns credit twice in this question.
• 💡Examiners reward a two sided argument, so prepare one point about prevention at the organisational level and one about treatment at the individual level.
• 💡Hook the answer to a debate you already revise: an individual level explanation of a structural problem is a ready made reductionism point.
• 💡If the question supplies a source about a company or a survey, quote from it, because application questions on this paper expect the stem to be used.
• 💡As a key question this can be assessed in two parts, the issue itself and the psychology that explains it, so keep the two answers separate.
• 💡Quote one figure you are certain of, such as the collapse in correct identifications among highly anxious visitors, rather than several you half remember.
• 💡When the command word is assess or discuss, decide your line before you start writing so the conclusion follows from the argument rather than arriving as a surprise.
• 💡Use the word testimony precisely, since much of the evidence concerns identification of a face, and saying so shows control of the material.
• 💡Key question items carry a large block of marks split between describing the issue and explaining it with psychology, so plan two sections and put a named study in every paragraph of the second.
• 💡The board can set this as a discuss or an assess, so hold one line of evidence for reform and one for abolition rather than arguing in a single direction.
• 💡Social psychology counts as usable content here, so majority influence during deliberation can be brought in provided you tie it to verdicts actually changing.
• 💡This is the most commonly prepared example, so make sure your version carries at least three named studies and reaches a position rather than shrugging.
• 💡Application marks are earned by advice, so write what a parent should look for in a setting and why, in the words the research uses.
• 💡If the stem describes a particular family, answer about that family and their circumstances rather than about parents in general.
• 💡This example rewards a plainly two sided structure, so plan one paragraph of evidence for benefit, one for harm, and a conclusion naming what the answer depends on.
• 💡Socially sensitive research is the easiest evaluation route here, so be ready to say how these findings have been used by adoption agencies and governments.
• 💡Name the longitudinal design as a strength, because the same children were assessed repeatedly rather than at a single point.
• 💡As a key question this splits into description and application, so keep prevalence and cost figures for the description and keep theory plus treatment evidence for the application.
• 💡Effectiveness questions want a ranked comparison and a judgement, not a list, so decide in advance which method you will argue is most effective and on what evidence.
• 💡The same material answers a treatment question elsewhere in the option, so learn one drug method and one behavioural method in enough detail to describe the procedure.
• 💡This is a discuss or to what extent question, so plan a case for, a case against and a conclusion that actually answers the extent rather than balancing forever.
• 💡Take in at least two named policies with an outcome attached to each, because one evaluated policy outscores three unevidenced ones.
• 💡Name the debates explicitly, since examiners credit free will and determinism, ethical implications and socially sensitive research when they are identified rather than implied.
• 💡Open your essay by explicitly writing the key question as a clear, interrogative title to frame your answer around a defined societal debate.
• 💡Use a dual-aspect paragraph structure: describe one specific real-world feature of the issue, then immediately apply a corresponding psychological theory to explain or solve it.
• 💡Incorporate specific empirical evidence (e.g., Sherif, Baddeley, Bandura, or Raine) to substantiate how psychological research supports your proposed solutions.

• Describing a riot as mindless or as contagion, which is precisely the account the evidence in this topic is used to argue against.
• Retelling Robbers Cave without extracting the usable part, that competition created hostility and only the joint tasks requiring cooperation reduced it, while simple contact did not.
• Proposing solutions with no psychology attached, such as longer sentences or more police, when the question asks how knowledge of social psychology would be used.
• Explaining heroism entirely by personality, when the specification points at situational evidence from the obedience variations and at social identity.
• Overstating the variation results, for example saying nobody obeyed once peers rebelled, when a minority still went to the end of the shock scale.
• Treating deindividuation and diffusion of responsibility as the same idea, when one concerns anonymity inside a group and the other concerns responsibility shared among witnesses.
• Describing the biology of plaques and tangles at length, which is biological psychology and earns little in a cognitive answer that is supposed to apply memory models.
• Treating dementia as one condition and as simply being forgetful, missing that different memory systems fail at different times, which is the very thing the cognitive models explain.
• Claiming that reminiscence or cognitive stimulation work treats or reverses dementia, when the evidence supports improved functioning and wellbeing rather than cure.
• Applying only the multi store model, so the everyday failures of attention and dual tasking that carers report go unexplained.
• Writing about dyslexia as seeing letters backwards, a description the evidence does not support and which no cognitive model explains.
• Describing the working memory model in full without ever saying what a weak phonological loop does to a child trying to read a word, so the application marks go unclaimed.
• Presenting the phonological account as the agreed explanation and ignoring visual, cerebellar and environmental accounts, which costs the assessment marks.
• Recommending interventions in general terms, such as more support or extra help, instead of naming a method and saying which cognitive difficulty it addresses.
• Writing that methadone cures heroin addiction, when maintenance manages dependence and harm rather than removing it.
• Confusing agonist with antagonist, so that methadone is described as blocking the receptor, which is what naltrexone does.
• Judging effectiveness by abstinence alone, when the trials that support the therapy measure retention and reduced use.
• Replacing evidence with opinion about whether people with addictions deserve treatment, which earns nothing in a psychology answer.
• Reading heritability as the proportion of the aggression of one individual that is caused by genes, when it describes variation across a population in a particular range of environments.
• Arguing only one side, when a question about implications expects both the protective uses of such evidence and its dangers.
• Listing implications with no psychology attached, so the answer becomes a general opinion piece about crime.
• Assuming a genetic account must lead to punitive policy, when it can equally support early support for at-risk families.
• Treating exposure as sufficient, which cannot be right when the same images reach almost everyone and only a small minority become ill.
• Sliding from correlation to cause when quoting media research, particularly where the comparison is between different people rather than the same people over time.
• Leaving out biological and family factors entirely, which makes the evaluation one-sided and caps the mark.
• Describing systematic desensitisation step by step and never answering whether airlines should provide it, which is the question actually asked.
• Assuming treatment always works, with no mention of the participants in the evidence who did not improve or who relapsed.
• Calling avoidance a punishment rather than a negative reinforcer, which reverses the mechanism keeping the phobia alive.
• Treating other cultures as one undifferentiated place and writing about the East as though it were a country, which loses the marks for specific named evidence.
• Assuming cultural variation proves mental illness is invented, when the stronger argument separates an underlying condition from the language available to express it.
• Confusing culture bias with cultural relativism: the first is a flaw in a measure that assumes one norm, the second is the claim that such judgements only hold within a culture.
• Offering Rosenhan as evidence about culture, when it is evidence about context and labelling inside a single country.
• Writing a business studies answer about bad managers with no psychology in it at all.
• Blurring everyday stress into a clinical diagnosis, instead of marking where a stress reaction ends and a depressive or anxiety disorder begins.
• Offering only individual level fixes such as mindfulness sessions, which invites the criticism that the organisation's own demands go unexamined.
• Quoting cost figures with false precision; give the scale and say whose review it came from rather than inventing a number.
• Answering entirely with misinformation experiments, so the argument never meets the evidence that witnesses to real crimes can be accurate over long delays.
• Treating every laboratory finding as directly applicable without noting that watching a film clip is not the same as witnessing a crime.
• Confusing recall of detail with recognition of a face, when a witness can be poor at one and better at the other and the courts treat them differently.
• Offering no verdict on a question that asks for one, or a verdict with no evidence attached to it.
• Writing a general essay on whether juries are a good idea with no named study in it, which leaves the psychology out of a question the board sets on psychology.
• Treating mock jury findings as descriptions of real verdicts, when the participants were often students reading a written summary alone, with no deliberation and no consequence for a defendant.
• Describing bias for the whole answer and never addressing the abolition half, so the response never reaches a judgement the examiner can credit.
• Answering only with Bowlby and concluding that any separation is damaging, which ignores the whole day care literature the question is about.
• Reporting correlational findings about hours of care as proof that day care causes aggression, when families using long hours differ in many other ways.
• Forgetting that the Strange Situation classifies a relationship under stress, so a child accustomed to separations may look avoidant without being insecure.
• Treating the Romanian findings as evidence about adoption in general, when those children had experienced extreme institutional privation that most adopted children have not.
• Claiming the research proves a critical period, when the researchers argued for a sensitive period in which later recovery is harder but not impossible.
• Ignoring the comparison group of children adopted within Britain, which is what makes the Romanian results interpretable at all.
• Recommending willpower or better information, when almost every smoker already knows the risks and knowledge alone predicts very little behaviour change.
• Quoting a success rate with no comparison group, so a figure is given that could be the rate people achieve unaided.
• Presenting aversion therapy as standard practice, when the evidence for it in smoking is weak and dropout is high.
• Treating electronic cigarettes as either obviously safe or obviously useless instead of citing the trial evidence on cessation and noting what remains unknown about long-term use.
• Confusing nicotine replacement, which substitutes the drug to ease withdrawal, with aversion therapy, which punishes the behaviour.
• Writing an opinion piece with no psychology and no evidence in it, which cannot reach the higher bands however reasonable it sounds.
• Treating all intervention as one thing, so that a seat belt law and a leaflet receive the same argument.
• Objecting that nudges are unethical because they work below awareness, without engaging with the reply that some default already exists whichever way it is set.
• Asserting that education is the best answer, which the evaluations of health campaigns do not support.
• Writing a generic sociopolitical opinion piece rather than grounding arguments in named psychological concepts, models, and empirical studies.
• Failing to adapt pre-prepared key question essays to the specific command word (e.g., giving a purely descriptive answer when the question asks to 'Assess' or 'Evaluate').
• Confusing the approach-specific requirements by applying biological explanations to a question that explicitly asks for a cognitive or social key question.

1. 1Step 1: Choose and write down one clear key question for each of the four core approaches (Social, Cognitive, Biological, Learning).
2. 2Step 2: Compile a fact file for each question containing 2-3 real-world statistics, key affected groups, and why it matters to modern society.
3. 3Step 3: Pair every real-world feature of the issue with at least two psychological concepts, one theory, and one empirical study from that topic.
4. 4Step 4: Draft timed 8-mark responses using 'Discuss' and 'Assess' command words, verifying that psychological mechanisms outweigh descriptive narrative.
5. 5Step 5: Review responses against Edexcel levels-based mark schemes to check for accurate terminology, conceptual depth, and sustained relevance.

• 📋8-mark 'Discuss the key question' essay: Requires a balanced explanation of the societal issue alongside appropriate theoretical psychological applications.
• 📋8-mark 'Assess the key question' essay: Requires psychological explanation combined with an evaluation of how effectively the theories explain or resolve the issue.
• 📋Short-answer application questions (3-4 marks): Typically presents a brief scenario or contemporary quote and asks to apply a specific approach's concept to it.
