欢迎来到心理学案例分析的实战指南。在这篇文章中，你将了解什么是案例研究、心理学家为什么依赖它们，以及如何分步骤分析真实或虚构的案例。你还将通过两个完整的案例练习，学会心理学家日常使用的思维工具。读完本文后，你将自信地应对任何 Year 7 的案例研究作业。

1. What Is a Case Study? | 什么是案例研究？

A case study is an in-depth investigation of a single person, a small group, or a unique event. Psychologists gather rich qualitative data through interviews, observations, diaries, and sometimes tests. Unlike large surveys that look for patterns across hundreds of people, a case study zooms in on the details of one life story.

案例研究是对单一个人、小群体或特殊事件的深度调查。心理学家通过访谈、观察、日记，有时还有测验来收集丰富的质性数据。与在数百人中寻找模式的大型调查不同，案例研究聚焦于一个生命故事的细节。

For example, instead of asking 500 teenagers about stress, a psychologist might spend six months studying one Year 7 student who is struggling with school anxiety. The goal is to understand the ‘how’ and ‘why’ behind behaviour, not just the ‘what’.

例如，心理学家与其调查 500 名青少年的压力，不如花六个月研究一名正在与学业焦虑作斗争的 Year 7 学生。其目标是理解行为背后的“如何”和“为什么”，而不仅仅是“是什么”。

2. Why Do Psychologists Use Case Studies? | 心理学家为什么使用案例研究？

Case studies are especially useful when a phenomenon is rare or when ethical boundaries stop us from doing experiments. We cannot cause brain injury to study its effects, but we can learn from the case of Phineas Gage, who survived a metal rod through his skull. Case studies also generate new hypotheses that can later be tested with larger samples.

当某种现象十分罕见，或者伦理界限阻止我们进行实验时，案例研究尤其有用。我们不能为了研究大脑损伤的影响而制造伤害，但我们可以从菲尼亚斯·盖奇的案例中学习，他的头骨被一根金属棒穿透后活了下来。案例研究还能产生新的假设，之后可以用更大的样本来检验。

In Year 7, you will use case studies to practise thinking like a psychologist: noticing details, linking evidence to theories, and suggesting real-world applications.

在 Year 7，你将通过案例研究来练习像心理学家一样思考：注意细节、将证据与理论联系起来，并提出现实中的应用建议。

3. The Core Steps of Case Analysis | 案例分析的核心步骤

Every case analysis follows four key moves. Think of them as the ‘DEPC’ model: Describe, Explain, Predict, Change.

每个案例分析都遵循四个关键动作。你可以把它们记作“DEPC”模型：描述 (Describe)、解释 (Explain)、预测 (Predict)、改变 (Change)。

Describe: Identify the main behavioural facts. What is the person doing, feeling, or thinking? Note triggers and consequences.
描述：找出主要的行为事实。这个人在做什么、感受什么、思考什么？记录触发因素和后果。
Explain: Link the behaviour to psychological theories or concepts (e.g., classical conditioning, cognitive biases, social learning).
解释：将行为与心理学理论或概念联系起来（例如，经典条件作用、认知偏差、社会学习）。
Predict: If nothing changes, what is likely to happen next? What would a theory forecast?
预测：如果没有任何改变，接下来可能会发生什么？某种理论会作出怎样的预测？
Change: Suggest an intervention based on your explanation. How could a therapist, teacher, or the person themselves improve the situation?
改变：根据你的解释提出一种干预措施。治疗师、教师或当事人本人如何改善当前状况？

4. Ethical Guidelines You Must Follow | 你必须遵守的伦理准则

When psychologists write about a real person, they follow strict ethical rules. Even in a classroom exercise, you should respect these principles.

当心理学家撰写有关真实人物的文章时，他们遵循严格的伦理规则。即使在课堂练习中，你也应该尊重这些原则。

Confidentiality: Use a fake name or initials. Never share private information that could identify the person.
保密：使用化名或姓名首字母。绝不透露可能识别出当事人的个人信息。
Informed consent: The participant (or their guardian) must agree to be studied and know they can withdraw at any time.
知情同意：参与者（或其监护人）必须同意被研究，并知道他们可以在任何时候退出。
Protection from harm: The study must not cause physical or psychological distress.
免受伤害：研究不得造成身体或心理上的痛苦。
Debriefing: After the study, researchers should explain the purpose and answer any questions.
事后解释：研究结束后，研究者应解释研究目的并回答任何问题。

5. Classic Case: Phineas Gage | 经典案例：菲尼亚斯·盖奇

In 1848, Phineas Gage was a railway worker in the USA. An explosion drove a 3-meter iron rod through his left cheek and out of the top of his skull. Miraculously, he survived and could walk and speak. However, his personality changed dramatically. Before the accident, he was responsible and polite; afterwards, he became impulsive, rude, and unable to stick to plans.

1848 年，菲尼亚斯·盖奇是美国的一名铁路工人。一次爆炸将一根 3 米长的铁棒从他的左脸颊穿入，从头顶穿出。不可思议的是，他活了下来，能走路、能说话。但他的性格发生了巨大变化。事故前，他负责且有礼貌；事故后，他变得冲动、粗鲁，无法坚持任何计划。

This case gave early evidence that the frontal lobes of the brain are involved in personality and self-control. Psychologists today might explain Gage’s behaviour using the biological approach: damage to the prefrontal cortex impaired his impulse regulation. A modern intervention would involve cognitive rehabilitation and social skills training.

这一案例提供了早期证据，证明大脑的额叶与人格和自控力有关。如今的心理学家可能会用生物学取向来解释盖奇的行为：前额叶皮层的损伤削弱了他的冲动调节能力。现代干预措施将包括认知康复和社交技能训练。

6. Practise Case 1: Alex’s Fear of Public Speaking | 实战案例 1：亚历克斯的公开演讲恐惧

6.1 Case Description | 案例描述

Alex is a 12-year-old Year 7 student. Two months ago, during a class presentation, he forgot his lines and his classmates laughed. Since then, Alex has refused to speak in front of more than two people. His heart races, his palms sweat, and he says ‘everyone will think I’m stupid’. His teachers note he is bright but his grades in subjects requiring presentations are dropping. He has started complaining of stomach-aches on presentation days.

亚历克斯是一名 12 岁的 Year 7 学生。两个月前，在一次课堂展示中，他忘了台词，同学们笑了起来。从那以后，亚历克斯拒绝在超过两个听众面前说话。他的心跳加速，手心出汗，他说“每个人都会觉得我很蠢”。老师们注意到他很聪明，但需要做展示的科目成绩正在下降。他开始在展示日抱怨胃痛。

6.2 Describe the Behaviour | 描述行为

Alex shows avoidance behaviour (refusing to speak publicly), physiological symptoms of anxiety (racing heart, sweating, stomach-aches), and negative self-talk (‘everyone will think I’m stupid’). The trigger is any situation involving an audience of three or more.

亚历克斯表现出回避行为（拒绝公开说话）、焦虑的生理症状（心跳加速、出汗、胃痛）和消极的自我对话（“每个人都会觉得我很蠢”）。触发因素是任何有三人或以上观众的情境。

6.3 Explain Using Two Approaches | 用两种取向解释

Behavioural explanation (classical conditioning): Alex was initially comfortable speaking. The laughter (unconditioned stimulus) caused embarrassment (unconditioned response). The classroom and the act of presenting (neutral stimulus) became associated with embarrassment. Now the presentation alone (conditioned stimulus) triggers anxiety (conditioned response). His avoidance reduces anxiety in the short term, which reinforces the fear (operant conditioning – negative reinforcement).

行为主义解释（经典条件作用）：亚历克斯原本不害怕说话。笑声（无条件刺激）引起了尴尬（无条件反应）。教室和展示行为（中性刺激）与尴尬建立了关联。现在仅仅展示本身（条件刺激）就引发了焦虑（条件反应）。他的回避在短期内减轻了焦虑，从而强化了恐惧（操作性条件作用——负强化）。

Cognitive explanation: Alex has developed a core belief: ‘I am not good enough at speaking.’ His thinking shows catastrophising (‘If I mess up, it will be a disaster’) and mind reading (‘Everyone will think I’m stupid’). These cognitive distortions keep the fear alive.

认知取向解释：亚历克斯形成了一个核心信念：“我不擅长说话。”他的思维中存在灾难化（“如果我搞砸了，那将是一场灾难”）和读心术（“每个人都会觉得我很蠢”）。这些认知扭曲使恐惧持续存在。

6.4 Predict and Suggest Change | 预测并提出改变方案

Prediction: Without intervention, Alex’s avoidance will generalise to other social situations, and his academic confidence will continue to fall.

预测：如果不进行干预，亚历克斯的回避行为将泛化到其他社交情境，他的学业自信将继续下降。

Intervention ideas: A behavioural approach might use systematic desensitisation – a step-by-step exposure hierarchy, from reading to one person up to speaking to the class, while practising relaxation. A cognitive approach would use CBT to challenge negative thoughts, keep a thought diary, and test beliefs through small experiments. Both approaches respect ethical guidelines: Alex must consent (with parental permission), can withdraw at any time, and his real name must be protected in any written report.

干预建议：行为主义取向可采用系统脱敏法——构建一个从给一个人朗读到在全班面前演讲的逐步暴露阶梯，同时练习放松技巧。认知取向会使用CBT来挑战消极思维，写想法日记，并通过小实验检验信念。两种方法都遵循伦理准则：亚历克斯必须同意（并获得家长许可），可以随时退出，在书面报告中必须保护他的真实姓名。

7. Practise Case 2: Annabelle’s Exam Worries | 实战案例 2：安娜贝尔的考试焦虑

7.1 Case Description | 案例描述

Annabelle, 11, used to enjoy maths. Since a difficult test three weeks ago, she says ‘my brain goes blank when I see numbers’. She cries before school on test days, has trouble sleeping, and has started telling friends she is ‘just bad at maths’. Her mother says Annabelle spends hours rewriting notes but never feels ready.

11 岁的安娜贝尔过去喜欢数学。三周前一次很难的测验后，她说“我一看到数字脑子就一片空白”。她在考试日上学前会哭，睡眠困难，还开始告诉朋友她“就是数学不行”。她的母亲说安娜贝尔花好几个小时重写笔记，但总觉得没准备好。

7.2 Apply DEPC | 应用 DEPC 模型

Describe: Crying, sleep trouble, blanking out, avoidance of maths talk, perfectionist note‑rewriting, and a fixed mindset statement (‘I’m just bad at maths’).

描述：哭泣、睡眠问题、头脑空白、回避谈论数学、完美主义式的反复抄写笔记，以及固定型思维表达（“我就是数学不行”）。

Explain: From a cognitive viewpoint, Annabelle holds maladaptive schemas about her ability (fixed mindset). The blanking out could be a working memory overload caused by anxiety. The biological approach might note that high cortisol from stress disrupts memory retrieval. The behavioural perspective would see test anxiety as a classically conditioned response to the test paper after a punishing experience (poor grade).

解释：从认知角度看，安娜贝尔对自身能力持有适应不良的图式（固定型思维）。空白感可能是焦虑导致的工 作记忆超载。生物学取向可能指出，压力导致的高皮质醇水平会干扰记忆提取。行为主义视角会将考试焦虑视为在惩罚性经历（差成绩）之后，对试卷形成的经典条件反应。

7.3 Intervention Design | 干预设计

A teacher or school counsellor could combine strategies: teach growth mindset language (‘I can’t do it yet’), introduce relaxation breathing before tests, and set small achievable revision targets to reduce perfectionism. The counsellor would need Annabelle’s and her mother’s informed consent and would keep session notes confidential.

老师或学校辅导员可以结合多种策略：教授成长型思维的表达（“我还做不到”），在考试前引入放松呼吸法，并设定可达成的小复习目标以减少完美主义。辅导员需要获得安娜贝尔和她母亲的知情同意，并对咨询记录保密。

8. How to Write a Top‑Quality Case Report in Year 7 | 如何写出 Year 7 高分案例报告

Your teacher will likely ask you to write a report with the following sections. Use this checklist:

你的老师很可能要求你写一份包含以下部分的报告。请使用这份清单：

Section	What to include
Title	‘Case Study of [Fake Name]’
Background	Age, context, reason for referral (brief, anonymous)
Behaviour Description	What the person does, feels, thinks; triggers; duration
Explanation	Link to at least two psychological approaches with evidence from the case
Prediction	What might happen without help, based on theory
Intervention	Practical, ethical suggestion linked to the explanation
Ethical Considerations	Confidentiality, consent, right to withdraw, debrief

报告部分	应包含内容
标题	[化名] 的案例研究
背景	年龄、情境、转介原因（简洁、匿名）
行为描述	此人做什么、感受什么、想什么；触发因素；持续时间
解释	至少联系两种心理学取向，并使用案例中的证据
预测	如果没有帮助，根据理论会发生什么
干预	与解释相关的、切实可行且符合伦理的建议
伦理考量	保密、知情同意、退出权、事后解释

9. Common Mistakes and How to Avoid Them | 常见错误及避免方法

Mistake 1: Just retelling the story. Avoid simply paraphrasing the case. Your job is to apply psychology concepts. After a sentence of fact, always add a sentence like ‘This shows…’ or ‘This fits the idea of…’.

错误 1：只是复述故事。避免仅仅改写案例。你的任务是应用心理学概念。在陈述事实后，一定要加上一句“这表明……”或“这符合……的概念”。

Mistake 2: Using only one explanation. Psychology is multi-perspective. Always aim for at least two approaches, even if one is covered very briefly.

错误 2：只使用一种解释。心理学是多视角的。始终力求至少两种取向，即使其中一个论述非常简短。

Mistake 3: Forgetting ethics. Even in a mock case, say how you would protect the participant’s privacy and wellbeing.

错误 3：忘记伦理。即使在模拟案例中，也要说明你将如何保护参与者的隐私和福祉。

Mistake 4: Vague intervention. ‘Give them counselling’ is too weak. Specify the type (e.g., CBT, systematic desensitisation) and a concrete step.

错误 4：干预措施模糊。“给他们提供咨询”过于空泛。应明确类型（如 CBT、系统脱敏）并写出具体步骤。

10. Key Terminology Bank | 关键术语库

Term	Definition
Case study	In-depth investigation of an individual or small group.
Qualitative data	Non-numerical information (e.g., interview quotes, observations).
Classical conditioning	Learning by association; a neutral stimulus triggers a response after being paired with an unconditioned stimulus.
Operant conditioning	Learning through consequences (reinforcement and punishment).
Negative reinforcement	Removing something unpleasant to increase a behaviour (e.g., avoiding a speech reduces anxiety).
Cognitive distortion	Inaccurate or exaggerated thought pattern (e.g., catastrophising).
Systematic desensitisation	Gradual exposure to feared situation while relaxed.
Confidentiality	Keeping participants’ identities and personal information private.

术语	定义
案例研究	对个体或小群体的深度调查。
质性数据	非数字信息（如访谈引语、观察记录）。
经典条件作用	通过关联进行学习；中性刺激与无条件刺激配对后引发反应。
操作性条件作用	通过后果（强化和惩罚）进行学习。

认知扭曲	不准确或夸大的思维模式（如灾难化）。
系统脱敏	在放松状态下逐渐暴露于恐惧情境。
保密	使参与者的身份和私人信息不公开。

11. Your Turn: Quick Self‑Quiz | 你的练习：快速自测

Read the mini‑case below and jot down one behavioural, one cognitive, and one ethical idea.

阅读下面的迷你案例，并草记一个行为主义观点、一个认知观点和一个伦理考量。

Mini‑case: Jayden, 12, used to love football. After missing a penalty kick that lost his team the match, he now refuses to join PE lessons and says ‘I’ll just let everyone down again.’ His coach reports he is talented but his self‑belief has vanished.

迷你案例：12 岁的杰登过去热爱足球。在他踢失点球导致球队输掉比赛后，他现在拒绝上体育课，并说“我只会再次让大家失望”。教练说他有天赋，但他的自信消失了。

Think about: What behaviour does Jayden show? (Describe.) What might cause it? (Explain – pick one conditioning or cognitive idea.) What ethical rule would you follow if you were to interview him?

想一想：杰登表现出什么行为？（描述。）可能是什么导致的？（解释——选择一个条件作用或认知概念。）如果你要采访他，你会遵循哪条伦理规则？

12. Final Tips and Summary | 最后建议与总结

Case studies are detective stories in psychology. Your job is not just to report but to explain and improve. Always connect back to a psychological theory, use precise vocabulary, and treat the person in the case with the same respect you would hope for yourself. Practise the DEPC steps with the examples above, and you will build a rock‑solid case analysis skill that will serve you all the way into IGCSE and beyond.

案例研究是心理学中的侦探故事。你的工作不仅仅是报告，还要解释和改善。始终回到心理学理论上，使用准确的词汇，并像你希望自己被尊重一样尊重案例中的人。用上面的例子练习 DEPC 步骤，你将建立起扎实的案例分析技能，这份技能将伴随你一直到 IGCSE 乃至更远。
