📚 A-Level AQA Psychology: Case Study Practice Drills | A-Level AQA 心理学：案例分析实战演练
Case study questions in AQA A-Level Psychology require more than simple recall; they demand that you apply theories, research, and ethical considerations to lifelike scenarios. This guide provides structured drills to help you master the skill of dissecting a case, linking it to psychological knowledge, and crafting answers that hit every mark on the specification.
AQA A-Level 心理学中的案例分析题不仅仅要求回忆知识点，更要求你将理论、研究和伦理考量应用到真实情景中。本指南通过结构化演练，帮助你拆解案例、联系心理学知识并写出符合评分标准的高分答案。
1. Introduction to Case Studies in AQA Psychology | AQA 心理学中的案例分析概述
In Papers 1 and 2 of the AQA specification, particularly within topics such as Memory, Attachment, Psychopathology, and Social Influence, you will encounter short scenarios describing a person’s behaviour or experiences. Your task is to identify which psychological concepts are illustrated, support your analysis with named studies, and often evaluate the research method implied or the ethics involved.
在AQA考纲的卷一和卷二中，尤其是在记忆、依恋、精神病理学和社会影响等主题中，你会遇到描述某人行为或经历的短情景。你的任务是识别所涉及的心理学概念，用指名研究支持分析，并常常评估所涉及的研究方法或伦理问题。
Case studies are not simply ‘stories’ – they are carefully designed assessment tools. A strong answer will seamlessly blend knowledge (AO1) with application (AO2) and critical evaluation (AO3). Our drills train you to move from reading a case to producing a coherent, exam-ready response in under five minutes.
案例分析不是简单的「故事」——它们是精心设计的评估工具。一份出色的答案会将知识(AO1)与应用(AO2)及批判性评估(AO3)无缝结合。我们的演练将训练你在五分钟内从阅读案例到产出一份连贯、适合考试的答案。
2. The 4-Step Approach to Case Study Analysis | 案例分析四步法
We recommend adopting the ‘IDEA’ framework: Identify the core issue, Describe and apply relevant psychological theory or research, Evaluate the methodology and ethical dimensions, and Articulate a concise conclusion. This approach ensures you never miss a mark for application or evaluation.
我们建议采用「IDEA」框架：识别核心问题(I)，描述并应用相关心理学理论或研究(D)，评估方法论和伦理维度(E)，并表述简洁的结论(A)。这个方法确保你不会在应用或评估上失分。
Identify: Underline key phrases in the scenario that hint at a specific disorder, attachment type, or memory failure. Describe: Link those clues to one or two well-chosen studies, e.g. ‘This mirrors the case of HM where…’ . Evaluate: Comment on the strengths and limitations of the case study as a method, or consider ethical issues such as confidentiality. Articulate: End with a sentence that ties your argument back to the question stem.
识别：在情景中划出提示特定障碍、依恋类型或记忆缺陷的关键短语。描述：将这些线索与一两个恰当的研究联系起来，例如「这与HM的案例相似，其中……」。评估：评论案例研究作为方法的优缺点，或考虑保密等伦理问题。表述：用一句话将你的论证回扣题目主干，形成结论。
3. Applying Psychological Knowledge: Memory | 应用心理学知识：记忆
Memory case studies often feature individuals who have suffered brain injury or who display selective forgetting. Your first step is to match symptoms to the multi-store model (MSM) or the working memory model (WMM). For example, a person who can remember old friends but not new nurses likely has impaired STM-to-LTM transfer, a classic feature of MSM. Cite Scoville and Milner’s patient HM to exemplify the separation of STM and LTM.
记忆案例研究通常会出现脑损伤患者或表现出选择性遗忘的个体。第一步是将症状与多贮存模型(MSM)或工作记忆模型(WMM)匹配。例如，一个能记得老朋友却记不住新护士的人，很可能存在短时记忆向长时记忆转移的障碍，这是MSM的经典特征。引用Scoville和Milner的病人HM可以阐明STM和LTM的分离。
Should the scenario involve difficulty following multi-step instructions, the central executive and phonological loop of the WMM become relevant. Reference Baddeley and Hitch’s dual-task experiments to show how the model explains specific impairments. Always name the researcher and key finding – the exam board rewards precise evidence.
如果情景涉及难以遵循多步骤指令，WMM中的中央执行器和语音回路就变得相关。引用Baddeley和Hitch的双任务实验来展示该模型如何解释特定损伤。始终指出研究者的姓名和关键发现——考纲奖励准确的证据。
4. Applying Psychological Knowledge: Attachment | 依恋
Attachment scenarios typically describe a child’s response to separation or reunion with a caregiver. Match the behaviour described – such as ‘ignores the mother on return’ or ‘alternates between clinging and hitting’ – to Ainsworth’s attachment types: secure, insecure-avoidant, and insecure-resistant. Then link to the Strange Situation procedure and, where appropriate, discuss cross-cultural variations, such as van IJzendoorn’s meta-analysis.
依恋情感情景通常描述儿童对与照料者分离或重聚的反应。将描述的行为——如「母亲回来时忽视她」或「在紧缠和击打间交替」——与Ainsworth划分的依恋类型匹配：安全型、不安全-回避型和不安全-反抗型。然后联系陌生情境实验，并在适当的时候讨论跨文化差异，比如van IJzendoorn的元分析。
For a deeper evaluation, many questions expect you to apply Bowlby’s concept of the internal working model. Explain how the child’s early relationship might shape future adult relationships, citing Hazan and Shaver’s ‘Love Quiz’ or Bowlby’s maternal deprivation hypothesis. This moves your answer from simple identification to psychological explanation.
为了更深层的评估，许多题目期待你应用Bowlby的内部工作模型概念。解释该儿童的早期关系如何可能塑造未来的成人关系，引用Hazan和Shaver的「爱情测验」或Bowlby的母性剥夺假说。这使你的答案从简单识别提升到心理学解释。
5. Applying Psychological Knowledge: Psychopathology | 精神病理学
Psychopathology case studies may describe a person with symptoms such as excessive hand-washing, persistent low mood, or delusions. Begin by assessing which of the four definitions of abnormality – deviation from social norms, failure to function adequately, statistical infrequency, and deviation from ideal mental health – best captures the individual’s condition, providing a short justification.
精神病理学案例研究可能会描述一个人有过度洗手、持续情绪低落或妄想等症状。首先评估四种异常定义——社会常模偏差、功能失调、统计罕见性和理想心理健康偏差——中哪一种最能概括该个体的状况，并提供简短的理由。
Then offer an explanation from the AQA specification: for OCD, draw on genetic and neural explanations (COMT gene, worry circuit); for phobias, apply the two-process model (classical conditioning plus operant conditioning). Evaluate by noting that case studies lack population validity and may oversimplify dual explanations. Mention ethical concerns around labelling, which link directly to the ‘Issues and Debates’ dimension.
然后从AQA考纲中选取一种解释：对于OCD，引用遗传和神经解释（COMT基因、担忧回路）；对于恐惧症，应用双过程模型（经典条件作用加上操作条件作用）。通过指出案例研究缺乏人群效度并可能过度简化二元解释来进行评估。提及关于贴标签的伦理关切，这直接联系到「议题与争论」维度。
6. Evaluating Research Methods in Case Studies | 评估案例研究中的研究方法
Many AQA questions ask you to discuss the research method used in the scenario. The case study method, often involving interviews, observations, and psychometric tests, generates rich, in-depth data but faces challenges in replicability and generalisability. Use the table below to structure your evaluation.
许多AQA题目要求你讨论情景中使用的研究方法。案例研究法通常涉及访谈、观察和心理测量测试，能产生丰富深入的数据，但在可重复性和推广性上面临挑战。使用下表中的结构来组织你的评估。
| Strength | Limitation |
|---|---|
| Provides detailed qualitative insight into unique phenomena (e.g., HM, Genie). | Findings cannot be statistically generalised due to small, unrepresentative samples. |
| High ecological validity when studying behaviours in real contexts. | Researcher bias may colour interpretation; retrospective accounts can be unreliable. |
| Ethical complexity can be managed through informed consent and anonymity. | Inability to establish cause-and-effect; relies on correlational or anecdotal evidence. |
Always link evaluations directly to the given scenario. If the case involves a brain-damaged individual, for instance, highlight that the idiographic approach reveals how one person copes, but cannot predict behaviour for all patients with similar trauma.
始终将评估直接联系到所给情景。例如，如果案例涉及一位脑损伤个体，要强调特殊规律研究法揭示了个体如何应对，但无法预测所有类似创伤患者的行为。
7. Ethical Considerations in Psychological Case Studies | 心理学案例研究中的伦理考量
AQA frequently embeds ethical dilemmas into case studies: a participant may not have given fully informed consent, or the case might reveal identifying details. Reference the British Psychological Society (BPS) Code of Ethics, focusing on consent, deception, protection from harm, and confidentiality. Illustrate with real studies – e.g., Elizabeth Loftus’s ‘Lost in the Mall’ study raised questions about false memory planting and potential harm.
AQA常常在案例中嵌入伦理困境：参与者可能没有给出完全知情同意，或者案例可能暴露身份细节。引用英国心理学会(BPS)伦理准则，聚焦于同意、欺骗、免于伤害和保密。用真实研究来说明——例如，Elizabeth Loftus的「商场走失」研究引发了关于植入虚假记忆和潜在伤害的问题。
In your answer, adopt a balanced stance: acknowledge that ethical guidelines are sometimes breached for scientific gain, but propose how the study could be redesigned (e.g., using presumptive consent, debriefing, or altering the methodology to an observational design) to meet ethical standards without sacrificing validity.
在答案中采取平衡立场：承认伦理指南有时为科学利益而被违反，但提出如何重新设计研究（例如，使用推定同意、事后解说或将方法改为观察设计）以满足伦理标准而不牺牲效度。
8. Crafting High-Mark Responses: Structure and Terminology | 高分答案的构建：结构和术语
Examiners expect a ‘point-evidence-explanation-link’ (PEEL) structure within each paragraph. Start with a clear topic sentence that answers the question; follow with a named piece of evidence; then elaborate how that evidence explains the case; finally, link back to the scenario. Avoid vague terms like ‘the case shows’; instead, write ‘the participant’s inability to recall recent events is consistent with…’.
考官期待每段使用「观点-证据-解释-联系」(PEEL)结构。以明确回答问题的主题句开头；接着给出指明证据；然后详细解释证据如何说明案例；最后回扣情景。避免模糊词汇如「该案例显示」，而是写「参与者无法回忆近期事件与……一致」。
Employ specialist terminology: ‘episodic buffer’, ‘internal working model’, ‘positive reinforcement’, ‘deviation from ideal mental health’. However, never use a term without defining it at first use; this demonstrates understanding. A phrase like ‘the central executive, which monitors and coordinates the slave systems, appears impaired because…’ simultaneously provides AO1 and AO2.
使用专业术语：「情景缓冲器」、「内部工作模型」、「正强化」、「理想心理健康偏差」。但每次首次使用术语时都要定义，以展示理解。像「中央执行器——它监控和协调从属系统——似乎受损，因为……」这样的措辞同时提供了AO1和AO2。
9. Common Pitfalls and How to Avoid Them | 常见错误及避免方法
Pitfall 1: Describing instead of applying. Merely recounting the multi-store model earns low marks. Instead, link each component directly to the scenario: ‘The sensory register would briefly hold the child’s mother’s face before encoding to STM…’. Pitfall 2: Ignoring the command word. ‘Outline’ requires description only; ‘Discuss’ demands evaluation with strengths and limitations. Read the question three times before you write.
错误1：描述而非应用。仅仅复述多贮存模型得分很低。相反，将每个成分直接联系情景：「感觉登录器会短暂保持孩子母亲的面孔，然后编码进入短时记忆……」。错误2：忽略指令词。「简述」只要求描述；「讨论」则需要带着优缺点进行评估。动笔前把问题读三遍。
Pitfall 3: Overly brief or generic evaluation. A sentence like ‘Case studies lack generalisability’ is insufficient. Expand with: ‘Because this single case of a 6-year-old girl with selective mutism cannot represent the wider population, the findings have low population validity and cannot be used to develop universal therapies.’ Pitfall 4: Forgetting to name researchers. Always credit: ‘According to Ainsworth (1978)…’ or ‘As demonstrated by Baddeley and Hitch (1974)…’. This lifts AO1.
错误3：评估过于简短或通用。像「案例研究缺乏推广性」这样的句子是不够的。扩展成：「由于这个选择性缄默症6岁女孩的单一案例无法代表更广泛人群，研究发现具有较低的人群效度，不能用来开发通用疗法。」错误4：忘记指名研究者。始终归功：「根据Ainsworth(1978)……」或「正如Baddeley和Hitch(1974)所证明……」。这提升AO1。
10. Practice Drill: Memory Case Study | 实战演练：记忆案例
Scenario: ‘Clive, 52, suffered a viral infection that damaged his hippocampus. Now he lives entirely in the present moment; he can recall events from before his illness but cannot form new lasting memories for people he meets daily. However, he can still play the piano from memory and retains his sense of humour.’
情景：「Clive，52岁，因病毒感染导致海马体受损。现在他完全活在当下；能回忆生病前的事件，但无法对每天见到的人形成新的持久记忆。然而，他仍能凭记忆弹钢琴，并保持着幽默感。」
Identify: This scenario illustrates a classic dissociation between episodic memory and procedural memory, as well as between retrograde and anterograde amnesia. The intact piano-playing points to preserved procedural memory, while the inability to form new personal experiences indicates impaired episodic memory consolidation.
识别：该情景说明了情景记忆与程序记忆之间的经典分离，以及逆行性与顺行性遗忘之间的分离。完好的钢琴演奏表明程序记忆得以保留，而无法形成新的个人经历则表明情景记忆的巩固受损。
Apply: Draw on the case of Clive Wearing, who showed similar symptoms. The working memory model can also be invoked: his phonological loop and visuospatial sketchpad likely function, but the episodic buffer cannot transfer information to LTM due to hippocampal damage. Mention Tulving’s (1972) division of LTM into episodic, semantic, and procedural.
应用：引用Clive Wearing的案例，他表现出类似症状。也可援引工作记忆模型：他的语音回路和视空间面板可能正常运作，但情景缓冲器因海马体受损而无法将信息传递至长时记忆。提及Tulving(1972)将长时记忆分为情景、语义和程序的分类。
Evaluate: This is a case study, so depth of detail compensates for lack of generalisability. Ethical concerns include ongoing consent and privacy, as the real Clive Wearing’s life has been widely publicised. The idiographic approach offers unique insights into memory structures, but it is hard to replicate. Suggest comparing this case with other hippocampal patients like HM to tentatively identify patterns.
评估：这是一个案例研究，因此细节深度弥补了推广性的不足。伦理关切包括持续同意和隐私，因为真实的Clive Wearing的生活已被广泛公开。特殊规律研究法为记忆结构提供了独特的洞见，但难以复制。建议将该案例与HM等其他海马体受损患者进行比较，以初步识别规律。
11. Practice Drill: Attachment Case Study | 实战演练：依恋案例
Scenario: ‘Four-year-old Maya attends nursery. When her mother leaves, Maya does not cry and continues playing. Upon reunion, she ignores her mother and turns away when approached. The nursery staff report that Maya is equally friendly with strangers as with her mother.’
情景：「四岁的Maya上幼儿园。母亲离开时，Maya不哭并继续玩耍。重聚时，她忽视母亲并在母亲靠近时转身。幼儿园工作人员报告，Maya对陌生人和对母亲一样友好。」
Identify: Maya’s behaviour matches the insecure-avoidant attachment type (Type A) as identified by Ainsworth et al. (1978). She shows low stranger anxiety, low separation anxiety, and avoidance on reunion, suggesting a dismissing relationship with her caregiver.
识别：Maya的行为符合Ainsworth等人(1978)识别的不安全-回避型依恋(A型)。她表现出低陌生人焦虑、低分离焦虑和重聚时的回避，暗示与照料者之间是一种疏离关系。
Apply: Explain the internal working model: Maya may have learned that her attachment figure is unresponsive, so she deactivates attachment behaviour. Link to research – for instance, Isabella et al. (1989) found that mothers of avoidant infants were more rejecting. Also discuss the Strange Situation procedure and note that this classification only captures one relationship, not Maya’s overall temperament.
应用：解释内部工作模型：Maya可能已了解到她的依恋对象不回应，因此她停用依恋行为。联系研究——例如，Isabella等人(1989)发现回避型婴儿的母亲更倾向于拒绝。同时讨论陌生情境程序，并指出这一分类只捕捉了一段关系，而不能代表Maya的整体气质。
Evaluate: The case study is based on naturalistic observation in a nursery, so ecological validity is high. However, observer bias may affect the recording of behaviour. Use the BPS ethical guidelines: maintain Maya’s anonymity and consider parental consent. To strengthen conclusions, a longitudinal follow-up could explore whether Maya’s attachment style changes in adolescence, relating to Hazan and Shaver’s continuity hypothesis.
评估：本案例研究基于幼儿园的自然观察，因此生态效度高。但观察者偏差可能影响行为记录。引用BPS伦理准则：保持Maya的匿名性并考虑家长同意。为加强结论，可进行纵向追踪以探索Maya的依恋风格在青春期是否改变，这与Hazan和Shaver的连续性假说相关。
12. Mark Scheme Insights and Self-Assessment | 评分标准解读与自我评估
After completing a practice drill, compare your answer against the AQA mark bands. For a 6-mark application question, a top-band response will demonstrate accurate and detailed application of at least two pieces of psychological knowledge, clear linkage to the scenario, and use of specialist terminology. A mid-band answer might merely identify a concept without elaboration or confuse evaluation with description.
完成一项实战演练后，将你的答案与AQA评分等级对照。对于一道6分的应用题，最高等级的答案会展示至少两个心理学知识点准确详细的运用、与情景的清晰联系以及对专业术语的使用。中等答案可能只识别概念而不展开，或将评估与描述混淆。
Create a self-assessment checklist: Did I name a researcher and study? Did I use words like ‘because’, ‘therefore’, ‘this means’ to build explanation? Did I include both a strength and a weakness of the method? Did I explicitly refer to the scenario in every paragraph? Tick each item to ensure you have hit all assessment objectives before moving on.
制作一份自我评估清单：我是否指出了一个研究者及其研究？我是否使用了诸如「因为」、「因此」、「这意味着」等词汇来构建解释？我是否包含了方法的一个优点和一个缺点？我是否在每段中都明确提到了情景？在前进之前，逐项核对以确保命中了所有评估目标。
