1. What Are Case Studies in Psychology? | 心理学中的案例研究是什么？
A case study is an in-depth investigation of a single individual, group, or event. In psychology, it gathers detailed, often longitudinal, data using methods such as interviews, observations, and psychometric tests. Unlike experiments, case studies do not manipulate an independent variable; they aim to provide a rich, holistic picture of the subject.
案例研究是对单一个体、群体或事件的深入调查。在心理学中，它通过访谈、观察和心理测量等方法收集细致的、常为纵向的数据。与实验不同，案例研究不操纵自变量；它旨在提供一幅丰富、整体的主体画像。
2. Key Features of a Psychological Case Study | 心理学案例研究的关键特征
Case studies often use triangulation – combining multiple research methods to enhance validity. They typically generate qualitative data, though quantitative measures can supplement. Features include idiographic focus (the unique individual), longitudinal tracking, and the exploration of rare phenomena that cannot be ethically replicated in experiments, such as brain trauma (e.g., Phineas Gage).
案例研究常使用三角验证法——结合多种研究方法来提高效度。它们通常产生质性数据，但也可辅以量化测量。特征包括特殊规律性焦点（独特的个体）、纵向追踪，以及探索无法在实验中伦理地复现的罕见现象，如脑损伤（例如菲尼亚斯·盖奇）。
3. Why Case Studies Matter in AQA Psychology | 案例研究在 AQA 心理学中的重要性
In the AQA specification, case studies are woven into topics such as memory (Patient KF), attachment (Bowlby’s 44 thieves), psychopathology (Little Hans), and social influence (Milgram’s participants). The exam expects you to describe the case, link it to theories, and evaluate its contribution. Mastering case study analysis will boost your performance on both short-answer and extended writing questions.
在 AQA 大纲中，案例研究贯穿于记忆（患者 KF）、依恋（Bowlby 的44名少年小偷）、心理病理学（小汉斯）和社会影响（米尔格拉姆实验的参与者）等主题。考试要求你描述案例、将其与理论联系并进行评价。掌握案例分析将提升你在简答题和论述题上的表现。
4. Step‑by‑Step Approach to Analysing a Case Study | 逐步分析案例研究的方法
Begin by reading the scenario carefully and highlighting key behavioural, emotional, or cognitive details. Then, identify which psychological concepts or theories (e.g., classical conditioning, working memory, attachment styles) are relevant. Next, apply the theory explicitly: ‘Because John experienced X, according to Y theory, he may develop Z.’ Finally, evaluate the case: consider alternative explanations, generalisability, and ethical issues.
首先仔细阅读情景，标出关键的行为、情绪或认知细节。然后，识别相关的心理学概念或理论（如经典条件反射、工作记忆、依恋类型）。接着，明确地应用理论：“因为约翰经历了X，根据Y理论，他可能会发展出Z。”最后，对案例进行评价：考虑替代解释、可推广性和伦理问题。
5. Common Topics and Classic Case Studies | 常见主题和经典案例研究
You should be familiar with the following iconic case studies. Each connects to a core topic:
你应当熟悉以下经典案例研究。每一个都关联一个核心主题：
- Memory: Patient KF – demonstrates separate short‑term memory stores; supports the Working Memory Model. | 记忆：患者 KF——证明了短时记忆的分立存储；支持工作记忆模型。
- Attachment: Bowlby’s 44 juvenile thieves – maternal deprivation hypothesis. | 依恋：Bowlby 的44名少年小偷——母爱剥夺假说。
- Social Influence: Individual case examples from Milgram’s obedience study (e.g., a participant who defied authority). | 社会影响：米尔格拉姆服从研究中的个别案例（例如某个反抗权威的被试）。
- Psychopathology: Little Hans – Freud’s explanation of phobias via the Oedipus complex. | 心理病理学：小汉斯——弗洛伊德通过俄狄浦斯情结解释恐惧症。
- Biopsychology: Phineas Gage – link between frontal lobe damage and personality change. | 生物心理学：菲尼亚斯·盖奇——额叶损伤与人格改变之间的关联。
6. Applying Theories to Cases: A Practical Example | 将理论应用于案例：实战范例
Let’s take a hypothetical case: ‘Lucy, aged 6, screams and cries when she sees any dog, after a large dog jumped on her last month.’ Using classical conditioning, the dog (neutral stimulus) became associated with pain/fright (unconditioned response), so now the dog alone (conditioned stimulus) triggers fear. Alternatively, social learning theory might suggest Lucy observed a caregiver reacting fearfully to dogs. In your answer, explain both possibilities before reaching a reasoned conclusion.
我们来看一个假设案例：“6岁的露西上个月被一只大狗扑倒后，现在一见到任何狗都会尖叫大哭。”运用经典条件反射，狗（中性刺激）与疼痛/惊吓（非条件反应）形成了联结，因此现在狗本身（条件刺激）就能引发恐惧。或者，社会学习理论可能认为露西观察到了照料者对狗表现出恐惧。在你的答案中，要先解释两种可能性，然后得出有论据的结论。
7. Evaluating Case Studies: Strengths and Limitations | 评估案例研究：优势与局限
Strengths include high ecological validity (real‑life context), rich qualitative detail, and the ability to study rare or unique cases that provide new hypotheses for further research. Limitations involve poor generalisability (small sample size), low reliability, and potential researcher bias – as the researcher may become too involved and lose objectivity. Always balance your evaluation when writing exam responses.
优势包括高生态效度（真实生活情境）、丰富的质性细节，以及能够研究罕见或独特的案例，为进一步研究提供新假设。局限包括可推广性差（样本量小）、信度低，以及潜在的研究者偏见——研究者可能过度介入而失去客观性。在撰写考试答案时，始终要平衡你的评价。
8. Using Real‑Life Scenarios: A Practice Exercise | 使用真实情景：练习
Read the following scenario: ‘A 15‑year‑old boy, Tom, refuses to attend school and becomes physically sick each morning. Teachers report he was bullied by older students last term.’ Identify two psychological explanations. (Tip: Use classical conditioning – school has become a conditioned fear stimulus; also consider operant conditioning – avoidance behaviour is negatively reinforced by reduction of anxiety.) Then evaluate which explanation is more plausible.
阅读以下情景：“15岁男孩汤姆拒绝上学，每天早晨都会感到身体不适。老师报告称他上个学期曾被高年级学生欺凌。”找出两种心理学解释。（提示：使用经典条件反射——学校已成为条件化恐惧刺激；同时考虑操作性条件反射——回避行为因焦虑减轻而得到负强化。）然后评估哪种解释更合理。
9. Exam‑Style Questions and Model Answers | 考试风格问题与模范答案
Typical question: ‘Use your knowledge of attachment to explain the behaviour of a child who is clingy and distressed when separated from their mother.’ In response, connect the case to Bowlby’s maternal deprivation or Ainsworth’s insecure‑resistant attachment. A model answer: ‘The child’s distress suggests an insecure‑resistant attachment (Type C), characterised by intense separation anxiety and conflicted reunion behaviour. This pattern may develop from inconsistent caregiving, where the caregiver is sometimes responsive and sometimes neglectful.’
典型问题：“运用你的依恋知识，解释一名孩子在离开母亲时表现得黏人且痛苦的行为。”回答时，将案例与 Bowlby 的母爱剥夺或 Ainsworth 的不安全-抵抗型依恋联系起来。模范答案：“孩子的痛苦表明这是一种不安全-抵抗型依恋（C 型），其特征为强烈的分离焦虑和矛盾的重聚行为。这种模式可能源于不一致的照料，即照料者时而回应时而忽视。”
10. Common Mistakes to Avoid | 常见错误避免
Many students fall into the trap of simply retelling the case without analysis. Avoid pure description. Do not forget to name the theory explicitly and use correct terminology (e.g., ‘conditioned stimulus’ not ‘scary thing’). Another error is neglecting evaluation – always add a sentence about limitations or alternative viewpoints. Finally, ensure your answer links back to the question stem throughout.
许多学生会陷入单纯复述案例而不分析的陷阱。要避免纯描述。不要忘记明确点出理论并使用正确的术语（例如“条件刺激”而非“可怕的东西”）。另一个错误是忽略评价——总是要添加一句关于局限性或替代观点的句子。最后，确保你的回答始终与问题题干相关联。
11. Integrating Research Methods: Case Study vs. Experiment | 整合研究方法：案例研究 vs. 实验
Understanding how case studies differ from experiments is crucial for method‑focused questions. Here is a quick comparison:
理解案例研究与实验的区别对于关注研究方法的题目至关重要。以下是快速对比：
| Feature | Case Study | Experiment |
|---|---|---|
| Manipulation of IV | No | Yes |
| Control over variables | Low | High |
| Typical data | Qualitative (rich detail) | Quantitative (numerical) |
| Generalisability | Limited | Higher (if large sample) |
In the AS exam, you might be asked to explain why a researcher chose a case study design. Reference these features, linking to the context of the given scenario.
在 AS 考试中，你可能会被要求解释为什么研究者选择了案例研究设计。引用这些特征，并将其与给定情景的背景联系起来。
12. Final Tips for Exam Success | 考试成功的最后提示
Practice by writing out responses to sample cases under timed conditions. Always highlight key concepts from the specification: for example, if the case involves memory loss, mention components of the multi‑store model or working memory. Keep an evaluation bank ready: ‘low population validity’, ‘retrospective data may be unreliable’, ‘rich insights into atypical development’. Use linking phrases such as ‘This is consistent with…’ or ‘However, an alternative perspective suggests…’ to demonstrate critical thinking.
通过限时写下样例案例的回答来进行练习。始终突出大纲中的关键概念：例如，如果案例涉及记忆丧失，就提及多存储模型或工作记忆的组成部分。准备好评价库：“低人口效度”、“回顾性数据可能不可靠”、“对非典型发展的丰富洞见”。使用“这与……一致”或“然而，另一种视角认为……”等关联短语来展示批判性思维。
