📚 Case Study Practical Drills for Year 10 CAIE Psychology | Year 10 CAIE 心理学：案例分析实战演练
Case studies are a central part of the CAIE Year 10 Psychology course, giving you the chance to apply theories and concepts to real-life situations. Whether you are analysing a famous study or responding to an exam question, the skill of breaking down a scenario systematically makes all the difference. This article provides a step-by-step guide to mastering case study analysis, complete with practical examples, checklists, and common pitfalls to avoid.
案例研究是 CAIE 十年级心理学课程的核心环节，让你有机会将理论和概念运用到真实生活情境中。无论你是在分析一项著名研究还是回答考试题目，系统性拆解情景的能力都至关重要。本文提供掌握案例分析的分步指南，配以实战示例、自查清单以及需要避开的常见误区。
1. Introduction to Case Studies in Psychology | 心理学案例研究简介
A case study is an in-depth investigation of a single person, group, event, or community. In psychology, it allows researchers to gather rich, detailed data that may not be accessible through experiments alone. For Year 10 learners, case studies appear both as stimulus material in exams and as evidence to support theoretical explanations.
案例研究是对单一个人、群体、事件或社区的深入调查。在心理学中，它使研究者能够收集到仅靠实验无法获得的丰富详细数据。对于十年级学生来说，案例研究既会作为考试中的背景材料出现，也会作为支撑理论解释的证据。
Well-known examples include the case of HM, who lost his ability to form new memories, and Genie, a child raised in extreme isolation. Your task is not just to retell the story but to link it to psychological concepts such as memory models, social influence, or developmental stages.
著名的例子包括无法形成新记忆的 HM 案例，以及在极度隔绝中长大的 Genie 案例。你的任务不仅仅是复述故事，还要将其与记忆模型、社会影响或发展阶段等心理学概念建立联系。
Always begin by reading the case study twice: once for the overall narrative, and once to highlight key terms that point to theories or methods. This habit will save you time during examinations.
始终以阅读案例研究两遍开始：第一遍了解大致内容，第二遍标出指向理论或方法的关键术语。这个习惯会在考试中为你节约时间。
2. Steps in Analysing a Case Study | 分析案例研究的步骤
Adopting a structured approach prevents you from missing important details. Use the following four-step sequence every time you encounter a new case study:
采用一套有条理的步骤可以避免遗漏重要细节。每次遇到新的案例研究时，请遵循以下四步顺序：
Step 1: Identify the key details. Note the participants, setting, behaviour observed, and methods used to collect data. For instance, look for clues about whether interviews, observations, or questionnaires were employed.
第一步：识别关键细节。 记下参与者、场景、观察到的行为以及收集数据所使用的方法。例如，留意有没有线索表明使用了访谈、观察还是问卷。
Step 2: Link to psychological approaches. Does the case illustrate features of the biological, cognitive, or sociocultural approach? Ask yourself which perspective best explains the behaviour described.
第二步：联系心理学取向。 这个案例是否体现了生物学、认知或社会文化取向的特点？问问自己哪种观点最能解释所描述的行为。
Step 3: Evaluate the evidence. Consider the strengths and limitations of the case study method itself — for example, high ecological validity vs. low generalisability. Also evaluate any specific ethical issues.
第三步：评估证据。 思考案例研究方法本身的优点与局限——例如，高生态效度与低可推广性。同时评估任何具体的伦理议题。
Step 4: Draw a conclusion. Summarise how the case supports or challenges a particular theory. If relevant, suggest an alternative explanation or a follow-up study.
第四步：得出结论。 总结该案例如何支持或挑战某一特定理论。如果相关，提出另一解释或后续研究建议。
Practise this sequence with a classmate using a sample case study from your textbook; the more you repeat it, the more automatic it becomes under exam pressure.
和同学一起用教科书中的示例案例练习这一顺序；重复得越多，在考试压力下就会越自动化。
3. Identifying Psychological Theories | 识别心理学理论
CAIE questions often ask you to 'apply concepts from psychology' to a given scenario. This requires you to spot which theory is most relevant. Three broad areas dominate Year 10 syllabuses:
CAIE 的题目常要求你将“心理学概念”应用于给定情景。这就需要你发现哪一个理论最为相关。三大领域主导着十年级课程大纲：
- Memory: multi-store model, reconstructive memory, and factors affecting eyewitness testimony.
- Social influence: conformity (Asch), obedience (Milgram), and bystander intervention.
- Development: attachment types (Ainsworth), cognitive development (Piaget), and early socialisation.
- 记忆： 多储存模型、重构记忆以及影响目击者证词的因素。
- 社会影响： 从众（Asch）、服从（Milgram）和旁观者干预。
- 发展： 依恋类型（Ainsworth）、认知发展（Piaget）和早期社会化。
When you read a case study such as 'A child refuses to explore a new room and clings to the mother', you should immediately think of insecure-resistant attachment. If the case describes a witness changing their story after discussing the event with others, you know reconstructive memory and post-event information are being hinted at.
当你读到类似“一名儿童拒绝探索新房间并紧黏着母亲”的案例研究时，你应立即想到不安全-抗拒型依恋。如果案例描述一位目击者与他人讨论事件后改变了说法，你就知道重构记忆和事后信息被暗示了。
A helpful technique is to keep a theory checklist beside you while practising. For each case, tick which theory fits and jot down one supporting quote from the text. Over time, your speed of recognition will increase.
一个有用的技巧是在练习时将理论清单放在手边。对每一个案例，勾出适合的理论并从文本中摘录一句支持性引语。久而久之，你的识别速度会提高。
4. Evaluating Research Methods | 评估研究方法
Case studies often blend multiple research methods. Your examiner wants to see that you can identify the method used and discuss its strengths and weaknesses in context.
案例研究常常混合多种研究方法。考官希望看到你能够辨识所使用的方法，并结合具体情境讨论其优缺点。
| Method | Common Strengths | Common Limitations |
|---|---|---|
| Interview | In-depth qualitative data; rapport | Social desirability bias; time-consuming |
| Observation | Natural behaviour; high ecological validity | Observer bias; cannot infer cause and effect |
| Questionnaire | Large sample; easy to replicate | Low response rate; fixed questions may miss nuance |
| 方法 | 常见优势 | 常见局限 |
|---|---|---|
| 访谈 | 深入的定性数据；融洽关系 | 社会赞许偏差；耗时 |
| 观察 | 自然行为；高生态效度 | 观察者偏差；无法推断因果关系 |
| 问卷 | 大样本；易复制 | 回收率低；固定问题可能遗漏细微差别 |
When evaluating, don't just list strengths and weaknesses — link them to the scenario. For example, if the case study involves a sensitive topic, point out that an interview might provide rich data but could cause distress, raising ethical concerns.
评估时不只列出优缺点——要将它们与情景联系起来。例如，如果案例研究涉及敏感话题，指出访谈可能提供丰富数据但可能造成痛苦，并引发伦理担忧。
5. Ethical Considerations | 伦理考量
Every psychological case study must adhere to ethical guidelines. In your analysis, you must comment on whether the study respected principles such as informed consent, right to withdraw, confidentiality, and protection from harm.
每一个心理学案例研究都必须遵守伦理准则。在你的分析中，必须评论该研究是否尊重了知情同意、退出权、保密以及免于伤害等原则。
Classic case studies often violated modern ethical standards. For example, in the case of Little Albert, the child was deliberately conditioned to fear a white rat without any attempt to reverse the fear, and no consent was sought from the family. In your answer, you could point out that the study would not be approved by an ethics committee today.
经典案例研究常常违反了现代伦理标准。例如，在小阿尔伯特案例中，孩子被故意建立起对白鼠的恐惧而没有任何消除恐惧的尝试，也没有征求家庭的同意。在你的答案中，你可以指出该研究在今天不会被伦理委员会批准。
Use the acronym P.R.I.C.E. to remember what to check:
- Protection from harm
- Right to withdraw
- Informed consent
- Confidentiality
- Effective debrief
用缩写 P.R.I.C.E. 记住需要核查的要点：
- Protection（免于伤害）
- Right to withdraw（退出权）
- Informed consent（知情同意）
- Confidentiality（保密）
- Effective debrief（有效事后解释）
Even if a case study is ethically sound, discuss why this matters for the validity of the data — distressed participants may not provide honest or reliable responses.
即使一个案例研究在伦理上无懈可击，也要讨论这对数据效度有何影响——痛苦的参与者可能无法提供真实可靠的反应。
6. Case Study 1: Memory and Eyewitness Testimony | 案例一：记忆与目击者证词
Scenario: After a robbery at a convenience store, a witness, Tom, confidently identifies a suspect from a police lineup. Two days later, Tom reads a newspaper article stating that the suspect has previous convictions for theft. When interviewed again, Tom adds new details about the suspect's clothing and claims he saw a weapon, even though no weapon was mentioned initially.
情景： 便利店发生抢劫后，目击者 Tom 信心十足地从警察列队中认出了一名嫌疑人。两天后，Tom 读到一篇报纸文章称该嫌疑人有盗窃前科。再次接受访谈时，Tom 补充了关于嫌疑人衣着的新细节，并声称看到了一把武器，尽管最初并未提及武器。
Analysis question: Explain Tom's change in testimony using the theory of reconstructive memory and the concept of post-event information.
分析问题： 运用重构记忆理论和事后信息的概念解释 Tom 证词的改变。
In this case, Tom’s memory has been altered by the newspaper article, a classic example of post-event information. According to Bartlett’s theory of reconstructive memory, memory is not a passive replay but an active reconstruction that can be distorted by schemas. Tom’s schema for 'criminal' likely contains the expectation that a suspect carries a weapon and has a detailed appearance, which explains why he now 'remembers' a weapon. The confidence he initially showed does not guarantee accuracy, as studies by Loftus and Palmer demonstrated that leading questions and new information can alter memory even when the witness feels certain.
在这个案例中，Tom 的记忆被报纸文章所改变，这是事后信息的经典例子。根据 Bartlett 的重构记忆理论，记忆不是被动的重播，而是主动的重构，可能被图式所扭曲。Tom 对于“罪犯”的图式可能包含嫌疑人携带武器并且外貌细节丰富的预期，这就解释了为什么他现在“记起”了一把武器。他最初展现的信心并不保证准确性，正如 Loftus 和 Palmer 的研究表明，引导性问题和新的信息即使证人感觉确定也能改变记忆。
To strengthen your analysis, mention that the case study highlights the real-world implication — the criminal justice system should avoid exposing witnesses to potentially biasing information after the event.
为了让分析更有力，可以指出该案例研究凸显了现实世界的影响——刑事司法系统应避免在事发后让目击者接触可能产生偏差的信息。
7. Case Study 2: Social Influence – Conformity | 案例二：社会影响 – 从众行为
Scenario: In a secondary school, a group of five friends takes a maths quiz. Four of them, who are confederates, deliberately give wrong answers to some easy questions. The true participant, Sam, initially gives correct answers but after hearing the others, begins to agree with the wrong answers in subsequent rounds, despite looking puzzled.
情景： 在一所中学，五个朋友一起参加数学小测验。其中四人（实验同谋）故意在一些简单题目上给出错误答案。真正的参与者 Sam 最初给出了正确答案，但在听到其他人的回答后，随后的几轮中开始赞同错误答案，尽管他露出困惑的表情。
Analysis question: Explain Sam's behaviour with reference to conformity and the Asch paradigm. Consider whether this is normative or informational social influence.
分析问题： 参照从众行为和 Asch 范式解释 Sam 的行为。思考这是规范性社会影响还是信息性社会影响。
Sam’s behaviour mirrors the findings of Solomon Asch’s conformity experiments. Because the task was unambiguous (a maths quiz), Sam was most likely influenced by normative social influence — the desire to fit in with the group and avoid rejection. The puzzled expression indicates that he privately disagreed but publicly conformed. In Asch’s terms, this is compliance. There is little evidence of informational social influence because the questions were easy, and Sam did not show signs of genuinely doubting his own ability; instead, he yielded to group pressure.
Sam 的行为与 Solomon Asch 从众实验的发现相似。因为任务清晰明确（数学测验），Sam 最有可能受到规范性社会影响——想要融入群体并避免排斥的愿望。困惑的表情表明他私下并不同意但公开从众了。用 Asch 的术语来说，这就是顺从。几乎没有信息性社会影响的证据，因为题目很简单，Sam 也没有表现出真正质疑自己能力的迹象；相反，他屈服于群体压力。
Apart from the theory, evaluate the ecological validity of this scenario. Classroom settings are natural for adolescents, giving the case high mundane realism. However, the small, all-male or all-female friendship group might not generalise to different cultures or age groups.
除了理论之外，评估这个情景的生态效度。课堂环境对青少年来说是自然的，使得该案例具有较高的日常真实性。然而，小规模的同性别朋友圈可能无法推广到不同文化或年龄组。
8. Case Study 3: Developmental Psychology – Attachment | 案例三：发展心理学 – 依恋
Scenario: In a school nursery, three-year-old Maya is left by her mother for the first time. Maya cries intensely and cannot be comforted by the staff. When her mother returns ten minutes later, Maya approaches her but then pushes her away and arches her back. The nursery teacher notes that Maya’s mother sometimes responds quickly to Maya’s needs but at other times is distracted and inconsistent.
情景： 在学校附属幼儿园，三岁的 Maya 的妈妈第一次离开她。Maya 大哭不止，工作人员无法安抚。十分钟后妈妈回来时，Maya 靠近妈妈但随即推开她并弓起背。幼儿园老师注意到 Maya 的妈妈有时会迅速回应 Maya 的需求，但另一些时候会分心且表现不一致。
Analysis question: Identify Maya’s attachment type and justify your choice with reference to Ainsworth’s 'Strange Situation' and the role of maternal sensitivity.
分析问题： 识别 Maya 的依恋类型，并参照 Ainsworth 的“陌生情境”和母亲敏感性的作用来论证你的选择。
Maya’s behaviour — distress on separation, ambivalence at reunion (seeking contact but then resisting) — matches the description of insecure-resistant (Type C) attachment as classified by Ainsworth. The mother’s inconsistent responsiveness fits the pattern of caregiving associated with this attachment type: the child cannot predict whether the caregiver will be available, leading to heightened anxiety and intense but conflicted reactions.
Maya 的行为——分离时痛苦、重聚时矛盾（寻求接触但又抵抗）——符合 Ainsworth 分类的不安全-抗拒型（C 型）依恋。母亲不一致的回应方式与这种依恋类型相关的养育模式相吻合：孩子无法预知照顾者是否会出现，导致焦虑加剧以及强烈但矛盾的反应。
In your evaluation, you can state that the nursery observation has high ecological validity because it captures natural parent–child interaction. However, cultural differences in attachment behaviour should be acknowledged — in some cultures, ambivalent behaviour might reflect different socialisation goals rather than insecurity.
在你的评估中，可以指出幼儿园观察具有高生态效度，因为它捕捉到了自然的亲子互动。然而，应承认依恋行为的文化差异——在某些文化中，矛盾行为可能反映不同的社会化目标，而非不安全性。
9. Applying the D.E.A.L. Framework | 运用D.E.A.L.框架
Once you have identified the relevant theory, a simple acronym — D.E.A.L. — can help you structure your written answer for high marks:
- Describe: Briefly outline the case study details.
- Explain: Link the details to psychological theories or studies.
- Apply: Show how the theory works in this specific context.
- Link back: Return to the question, offering a concluding statement that addresses the command term.
一旦你识别出相关理论，一个简单的缩写——D.E.A.L.——能帮助你构建高分书面答案：
- D（描述）：简要概述案例研究细节。
- E（解释）：将细节与心理学理论或研究联系起来。
- A（应用）：展示该理论如何在此特定情境中发挥作用。
- L（回扣）：回到问题，给出针对指令词的结论性陈述。
For example, using the Maya case study above: (D) Maya shows distress at separation and ambivalence at reunion. (E) This pattern mirrors Ainsworth’s Type C insecure-resistant attachment. (A) Her mother’s inconsistent sensitivity can explain this because the child does not learn a stable internal working model of responsiveness. (L) Therefore, Maya’s behaviour supports the idea that early caregiving quality directly influences attachment security.
例如，运用上面的 Maya 案例：(D) Maya 在分离时表现出痛苦，重聚时表现矛盾。(E) 这种模式与 Ainsworth 的 C 型不安全-抗拒型依恋相似。(A) 其母亲不一致的敏感性可以解释这一点，因为孩子没有学会关于回应性的稳定内部工作模型。(L) 因此，Maya 的行为支持了早期养育质量直接影响依恋安全性的观点。
Practice writing one D.E.A.L. paragraph each week using different case studies. By the exam, you will be able to produce a well-structured evaluation in under ten minutes.
每周用不同的案例研究练习写一个 D.E.A.L. 段落。到考试时，你就能在十分钟内写出结构良好的评估。
10. Common Mistakes and How to Avoid Them | 常见错误及避免方法
Many Year 10 students lose marks not because they do not know the theory, but because of predictable mistakes in case study analysis. Watch out for these:
许多十年级学生失分不是因为不懂理论，而是因为案例分析中可预料的错误。请注意以下问题：
1. Storytelling instead of analysing. Do not simply summarise the case study. Every sentence must serve the purpose of explaining, applying, or evaluating. If you find yourself writing 'This is about a boy who...' without linking to psychology, stop and add a theoretical connection.
1. 讲故事而非分析。 不要只总结案例研究。每个句子都必须服务于解释、应用或评估的目的。如果你发现自己写着“这是一个关于一个男孩……的故事”而没有联系心理学，停下来并添加理论关联。
2. Ignoring the command term. 'Explain' requires detailed reasons; 'Discuss' asks for strengths and limitations; 'Evaluate' expects a judgement. Highlight the command term before you start writing.
2. 忽视指令词。 “解释”要求给出详细理由；“讨论”要求优缺点；“评估”期待一个判断。在开始写作前先标出指令词。
3. Using generic evaluations. A statement like 'Case studies have low generalisability' is true but insufficient unless you justify it by referring to the specific case (e.g., '...because Maya’s behaviour was observed in a single nursery in London, so it may not apply to children in extended-family cultures').
3. 使用通用评价。 像“案例研究可推广性低”这样的陈述是真实的，但不够充分，除非你通过引用具体案例来论证（例如，“……因为 Maya 的行为是在伦敦单一幼儿园观察到的，可能不适用于扩展家庭文化中的儿童”）。
4. Missing the ethical dimension. Even if the question does not explicitly ask for ethics, a well-placed ethical point can demonstrate higher-order thinking. Always consider whether the study respected the P.R.I.C.E. guidelines.
4. 遗漏伦理维度。 即使题目没有明确要求伦理考量，一个恰当的伦理观点也能展现高阶思维。始终考虑研究是否遵守了 P.R.I.C.E. 准则。
11. Practice Exam-Style Question | 模拟考题演练
Question:
Tom is a Year 10 student who has just moved to a new school. He notices that all his classmates stand up when the teacher enters the room, even though there is no official rule. Tom initially remains seated but after three days, he also starts to stand up. The teacher smiles at the class when they stand.
Using your knowledge of social influence, explain why Tom’s behaviour has changed. (6 marks)
题目：
Tom 是一名刚转学到新学校的十年级学生。他注意到所有同学在老师进教室时都起立，尽管并没有正式规定。Tom 起初仍然坐着，但三天后他也开始起立。老师看到大家起立时会微笑。
运用你的社会影响知识，解释 Tom 的行为为何发生了改变。（6 分）
Model Answer:
Tom’s behaviour can be explained by both normative and vicarious reinforcement. Initially, he conformed due to normative social influence — the desire to fit into the new peer group and avoid appearing disrespectful. The unanimous behaviour of his classmates created group pressure similar to that seen in Asch’s experiments. Over time, the teacher’s smile acted as vicarious reinforcement; Tom observed the class receiving a positive reaction and learned that standing up leads to approval. This combines elements of social learning theory, where observation of consequences shapes behaviour. Additionally, the fact that Tom changed his behaviour despite the absence of an official rule highlights the power of informal social norms.
参考答案：
Tom 的行为可以通过规范性社会影响和替代性强化来解释。起初，他因为规范性社会影响而从众——希望融入新的同伴群体并避免被视为不尊重。同学们一致的行为制造了类似 Asch 实验中的群体压力。之后，老师的微笑起到了替代性强化的作用；Tom 观察到全班得到积极回应，从而习得起立会带来认可。这结合了社会学习理论的要素，即对后果的观察塑造行为。此外，尽管没有正式规定 Tom 仍改变了行为，凸显了非正式社会规范的力量。
This answer directly addresses the command term 'explain', links to named studies, and avoids mere storytelling. Practising with six-mark questions like this will sharpen your ability to combine theory and evidence concisely.
这一答案直接针对指令词“解释”，联系了具名研究，并且避免了单纯叙述。用这样的六分题进行练习，将提升你简明结合理论与证据的能力。
12. Conclusion | 结语
Case study analysis in Year 10 CAIE Psychology is a skill that improves with deliberate practice. By following the step-by-step guide, learning to identify theories rapidly, and using frameworks like D.E.A.L. and P.R.I.C.E., you can transform a potentially intimidating task into a reliable source of marks. Remember to always read the case with a 'psychological lens', asking not just what happened, but why and how it supports or challenges existing psychology. With continued practice, you will find that case study questions become an opportunity to showcase your understanding rather than a challenge to fear.
十年级 CAIE 心理学中的案例分析是一项通过刻意练习可以不断提升的技能。遵循分步指南，学会快速识别理论，并使用 D.E.A.L. 和 P.R.I.C.E. 等框架，你就能够将可能令人畏惧的任务转变为可靠的得分来源。始终记得用“心理学视角”阅读案例，不仅要问发生了什么，更要问它为什么会发生以及它如何支持或挑战现有心理学知识。通过持续练习，你会发现案例研究类题目会成为你展示理解的机会，而不再是令人生畏的挑战。
