AQA A-Level Psychology Paper 1 Essays: Memory Essay Questions and Answer Hints
AQA A-Level Psychology Paper 1 Memory essays
For 16 mark essay questions, knowing the content is only part of the job. A strong answer needs to stay focused on the precise wording of the question and use research to develop an argument, rather than simply describing studies.
Discuss the coding, capacity and duration of the sensory register, short-term memory and long-term memory.
How to answer this question
There are three memory stores and three features named in the question. Your answer therefore needs to cover coding, capacity and duration for the sensory register, short-term memory (STM) and long-term memory (LTM).
A clear approach is to organise the descriptive part of the essay by memory store. For each store, explain its coding, capacity and duration, then use research evidence to support or challenge the proposed differences.
Do not turn the essay into a list of numbers. The discussion should consider how convincing the research is and whether coding, capacity and duration really support the idea that these are distinct stores.
Indicative points
You could include:
The sensory register receives information from the senses.
Coding is modality-specific, for example visual information is coded visually.
Capacity is very large because sensory information is constantly entering the system.
Duration is extremely brief unless attention is paid to the information.
Sperling's research can be used as evidence concerning the capacity and duration of visual sensory memory.
STM has a limited capacity.
Digit span research can be used to investigate STM capacity.
STM duration is limited without rehearsal, with Peterson and Peterson's research providing relevant evidence.
STM is predominantly acoustically coded, although this should not be interpreted as meaning it can only use acoustic information.
LTM has a potentially very large or unlimited capacity.
Its duration may extend over many years or potentially a lifetime.
LTM is predominantly semantically coded.
Baddeley's research can be used when discussing differences between coding in STM and LTM.
Bahrick's research provides evidence concerning very long duration in LTM.
The 2025 mark scheme, for example, credits Baddeley's finding that acoustically similar words were harder to recall immediately, while semantically similar words caused greater difficulty after a longer delay.
For evaluation, consider:
the high control of laboratory memory research
the artificial nature of tasks involving word lists, digits and trigrams
whether findings generalise to meaningful everyday memories
individual variation in memory capacity
whether the differences support genuinely separate memory stores
Discuss the working memory model.
How to answer this question
Begin by explaining that the working memory model presents short-term memory as an active processing system, rather than one single temporary store.
Make sure you cover all four main components:
central executive
phonological loop
visuo-spatial sketchpad
episodic buffer
You should also explain how the components work together, particularly when people perform two tasks at once.
For discussion, use research evidence to assess whether the model successfully explains working memory.
Indicative points
You could include:
The central executive directs attention and allocates processing resources.
It has a limited capacity.
The phonological loop processes verbal and acoustic information.
It includes processes involved in temporary storage and rehearsal of verbal material.
The visuo-spatial sketchpad temporarily stores and processes visual and spatial information.
Different components allow some tasks to be performed simultaneously if they use different processing systems.
Two tasks competing for the same component are more likely to interfere with each other.
The episodic buffer integrates information from different components and provides a link with LTM.
The model therefore portrays short-term memory as an active system rather than a passive storage box.
Useful evaluation could include:
dual-task research, which supports the existence of separate components
the case of KF, whose pattern of impairment supports separate visual and verbal short-term systems
brain-imaging evidence suggesting different areas are involved in different working-memory tasks
the practical value of understanding different processing deficits
the central executive being relatively vague compared with the more clearly described subsystems
some supporting evidence coming from artificial laboratory tasks
A useful examiner warning is not to confuse the episodic buffer with episodic memory. The 2022 examiner report also noted that some students incorrectly criticised the model for failing to explain the structure of LTM, even though the working memory model was not designed to model LTM itself.
Discuss the strengths and limitations of describing memory as a collection of separate stores or components.
How to answer this question
This question is broader than simply "describe the multi-store model" or "describe the working memory model".
The key phrase is separate stores or components. You need to consider how useful it is to divide memory into distinct parts.
A strong structure would compare the multi-store model, which distinguishes the sensory register, STM and LTM, with the working memory model, which divides short-term processing into several components.
Indicative points
You could include:
The multi-store model proposes structurally separate sensory, short-term and long-term stores.
These stores differ in coding, capacity and duration.
Evidence showing different patterns of coding and duration supports the idea that STM and LTM are distinguishable.
The working memory model challenges the idea that STM is one single store.
It divides working memory into the central executive, phonological loop, visuo-spatial sketchpad and episodic buffer.
Dual-task performance supports the idea that verbal and visual-spatial processing can operate relatively independently.
Evidence from individuals with selective memory impairment can also support the existence of separate systems.
For discussion, consider:
dividing memory into components has generated testable predictions
separate components can explain why some combinations of tasks interfere while others do not
the working memory model provides a more active account of short-term processing than the multi-store model
complete separation may be an oversimplification because different components clearly interact
the central executive remains less clearly specified than other components
highly controlled laboratory evidence may not always represent the complexity of everyday remembering
different models may be useful for different aspects of memory rather than one model providing a complete explanation
The strongest essays should avoid treating this as two unrelated mini-essays. Keep returning to the central issue: how convincing is the idea that memory can be divided into distinct stores or components?
Discuss interference as an explanation for forgetting.
How to answer this question
Make sure you explain both forms of interference:
proactive interference
retroactive interference
The core idea is that forgetting occurs because memories compete or become confused with one another, particularly when the information is similar.
Then evaluate how successfully interference accounts for forgetting.
Indicative points
You could include:
Interference occurs when one memory disrupts the ability to recall another memory.
It is particularly likely when memories are similar.
Proactive interference occurs when an older memory interferes with a newer memory.
Retroactive interference occurs when newly learned information disrupts an older memory.
Similar material can create greater competition between memories.
Interference does not necessarily mean that a memory has disappeared, but that successful retrieval has been disrupted.
Research evidence can be used to investigate the effect of similarity and competing information.
Useful evaluation could include:
controlled research demonstrating interference effects
evidence from more realistic situations, such as memory for information accumulated over time
interference research often uses artificial lists of words or similar materials
the effect may depend heavily on similarity between the competing memories
alternative explanations such as retrieval failure due to absence of cues
evidence that providing appropriate cues can restore apparently forgotten information
The 2025 examiner report is especially useful here. Stronger responses used supporting research, contradictory evidence, alternative explanations such as retrieval failure and real-life applications. Weaker responses often gave generic methodological criticisms without explaining what they meant for interference theory itself.
Discuss retrieval failure as an explanation for forgetting.
How to answer this question
The central idea is that information may still exist in LTM but cannot be retrieved because an appropriate cue is absent.
Explain the encoding specificity principle, then distinguish between context-dependent and state-dependent cues.
For evaluation, ask whether changing or reinstating cues really changes recall, and whether retrieval failure can explain all forgetting.
Indicative points
You could include:
Retrieval failure occurs when stored information cannot be accessed because suitable cues are unavailable.
According to the encoding specificity principle, cues present when a memory is encoded can become associated with that memory.
Recall is more successful when similar cues are available at retrieval.
Context-dependent forgetting occurs when the external environment at recall differs from that at encoding.
State-dependent forgetting occurs when the person's internal physical or psychological state differs.
Godden and Baddeley's research can be used to illustrate context-dependent retrieval.
The explanation suggests that some apparently forgotten information is still available but temporarily inaccessible.
Useful discussion points include:
experimental evidence supporting the effect of retrieval cues
practical applications to revision and recall
some context effects may be relatively small outside highly contrasting environments
cues may be more important for free recall than for recognition
artificial materials can limit the validity of supporting research
interference provides an alternative explanation of some forgetting
The 2024 examiner report found that students usually knew the basic explanation, including the encoding specificity principle, but evaluation was weaker when criticisms of supporting studies were not linked back to retrieval failure itself.
Discuss leading questions as a factor affecting the accuracy of eyewitness testimony.
How to answer this question
Keep the focus on eyewitness accuracy. Explain what a leading question is, how its wording may influence an eyewitness and then use psychological research to assess how serious the effect is.
Loftus and Palmer is particularly useful, but you should explain what the findings demonstrate about memory, rather than writing a long description of the experiment.
Indicative points
You could include:
A leading question contains information or wording that encourages a particular answer.
Leading questions can introduce misleading information after an event.
This can change a witness's estimate or account of what happened.
Loftus and Palmer manipulated the verb used when asking participants about a car accident.
Different verbs produced different estimates of speed.
Later questioning about features such as broken glass can provide evidence that misleading information may influence subsequent recall.
Leading questions could influence the response a witness gives without permanently altering the original memory.
Alternatively, post-event information may become incorporated into the witness's reconstructed memory.
The practical implication is that police interview questions should be carefully worded.
For discussion, consider:
experimental control over the wording of questions
replication of misleading-information effects
whether watching films has the same emotional impact as witnessing a real crime
demand characteristics
whether the effect represents genuine memory distortion or merely a change in the answer given
comparison with post-event discussion and anxiety as other influences on EWT
Discuss the effect of post-event discussion on the accuracy of eyewitness testimony.
How to answer this question
Post-event discussion is not the same thing as leading questions.
Here, the focus is on what happens when witnesses talk to other people after an event and encounter information that may differ from what they originally saw.
A good answer should explain both the effect and the psychological mechanisms that could produce it.
Indicative points
You could include:
Witnesses may discuss an event with co-witnesses after it has happened.
Details supplied by another witness can contaminate a person's own account.
This can result in inaccurate recall, false details or memory conformity.
A witness may repeat another person's account because of social pressure.
Source monitoring errors may occur when the witness remembers information but cannot identify whether it came from the original event or from later discussion.
Gabbert and colleagues provide research evidence for co-witness contamination.
In one study, participants who had discussed an event sometimes reported information that they could only have obtained from the other witness.
Useful discussion could include:
research support for memory conformity
whether warning witnesses about contamination reduces the effect
laboratory control versus the realism of eyewitness situations
difficulty distinguishing genuine memory distortion from conformity
comparison with leading questions
practical implications, such as separating witnesses before obtaining statements
The 2024 examiner report found that stronger answers made good use of Gabbert's research, source monitoring and memory conformity. Many weaker responses had too little psychological content and remained descriptive.
Discuss research into the effects of anxiety on the accuracy of eyewitness testimony.
How to answer this question
The important point is that the relationship between anxiety and eyewitness accuracy is not straightforward.
Research suggests anxiety can sometimes reduce accuracy but can also improve memory in real-life situations. A strong essay should therefore explain and evaluate this apparent contradiction rather than claiming that anxiety simply makes eyewitness testimony worse.
Indicative points
You could include:
Anxiety may narrow attention onto a threatening stimulus.
This may leave fewer attentional resources available for peripheral details.
Weapon focus provides one explanation for reduced identification accuracy.
Johnson and Scott's research can be used as evidence for reduced identification under threatening conditions.
Research using violent or emotionally arousing material has also found impaired recall.
However, real-life studies have sometimes found that witnesses experiencing high anxiety have very accurate memories.
Yuille and Cutshall's research can be used as evidence from a real-life crime.
Research has therefore produced apparently contradictory findings.
The inverted-U hypothesis proposes that performance may improve as arousal rises to an optimum level but deteriorate at very high levels.
For discussion, consider:
laboratory studies allow greater control but may create relatively weak anxiety
real-life studies have greater ecological validity but less control over extraneous variables
ethical constraints make it difficult to create genuine fear experimentally
the apparent weapon-focus effect might partly be caused by unusualness or surprise, rather than anxiety itself
different levels of anxiety may explain contradictory findings
witnesses may remember central and peripheral details differently
The 2023 examiner report noted that stronger students dealt explicitly with the contradictory evidence, using research such as Johnson and Scott and Yuille and Cutshall, rather than simply listing studies.
Discuss the usefulness of the cognitive interview as a technique for improving eyewitness recall.
How to answer this question
Because the question asks about usefulness, do not spend the entire essay describing the cognitive interview.
You need enough AO1 to explain the main techniques, but the discussion should then assess whether they actually improve eyewitness recall and whether the interview is practical for real police investigations.
For every technique, try to explain why it should improve retrieval.
Indicative points
You could include:
Report everything: witnesses are encouraged to recall every detail, even if it appears trivial.
Apparently unimportant details may act as cues for further memories.
Reinstate the context: witnesses mentally reconstruct the physical and psychological context in which the event occurred.
This can provide retrieval cues and links to the encoding specificity principle.
Recall in a different order: witnesses may recount events backwards or begin from different points.
This can reduce reliance on expectations and schemas.
Change perspective: witnesses attempt to recall the event from another viewpoint.
This may encourage retrieval of information not accessed through the original sequence of recall.
Enhanced versions of the cognitive interview can also improve communication and the relationship between interviewer and witness.
Useful discussion could include:
evidence that cognitive interviewing can increase the amount of correct information recalled
its clear practical application to police interviewing
increased recall is useful only if accuracy is maintained
the full procedure can be time-consuming
interviewers require training to use the techniques effectively
some components may be easier and more useful to apply than others
changing perspective may be difficult for some witnesses
mental context reinstatement has theoretical support from retrieval-failure research
the technique cannot remove every source of eyewitness error, particularly if memory has already been contaminated by misleading information
A useful exam technique is to avoid simply naming the four techniques. The June 2022 mark scheme required explanation of how techniques could improve recall, for example by generating cues or disrupting the influence of expectations.
Final tips for AQA A-Level Psychology Memory essays
Across these Memory essays, several patterns are worth remembering:
Follow the wording exactly. If the question asks about anxiety, do not drift into a general essay about eyewitness testimony.
Learn the distinctions. Proactive and retroactive interference, context and state cues, leading questions and post-event discussion are easy areas to confuse.
Use studies as evidence, not decoration. State what the findings mean for the explanation or model you are evaluating.
Link methodological evaluation back to the psychology. "The study was artificial" is not enough. Explain how that affects confidence in the explanation.
Compare explanations where useful. Interference versus retrieval failure is particularly effective.
Be precise with the working memory model. The episodic buffer is not episodic memory, and the central executive is not simply another storage system.
For eyewitness testimony, think about practical implications. Interviewing techniques, question wording and witness separation all show why the research matters outside the laboratory.
