📚 Year 7 CAIE Psychology: Case Study Practice in Action | 七年级 CAIE 心理学：案例研究实战演练

Case studies are one of the most fascinating ways psychologists explore human behaviour. Instead of running large-scale experiments, they look closely at a single person, group, or event to uncover deep insights. This article will walk you through what case studies are, why they are used, and how you can practise analysing them like a real psychologist. By the end, you will have sharpened your critical thinking and be ready to tackle any case study question that comes your way.

案例研究是心理学家探索人类行为最迷人的方式之一。他们不是进行大规模实验，而是仔细观察单个人、群体或事件，从而发现深刻的洞察。本文将带你了解什么是案例研究、为什么使用它们，以及你如何像真正的心理学家一样练习分析案例。最终，你将提高批判性思维能力，为应对任何案例研究问题做好准备。

1. What Is a Case Study? | 什么是案例研究？

A case study is an in-depth investigation of one individual, group, or institution. In psychology, it often focuses on a unique or rare situation that cannot be replicated in a lab. For example, a psychologist might study a child who grew up in extreme isolation to understand language development.

案例研究是对一个个体、群体或机构的深入调查。在心理学中，它通常关注无法在实验室复制的独特或罕见情况。例如，心理学家可能会研究一个在极度孤立环境中长大的孩子，以了解语言发展。

Unlike surveys that collect surface-level data from many people, case studies gather rich, detailed information using interviews, observations, and sometimes psychological tests. The goal is to build a full picture of the subject over a period of time.

与从许多人那里收集表面数据的调查不同，案例研究通过访谈、观察，有时还有心理测试，收集丰富、详尽的信息。目标是在一段时间内构建出研究对象的完整画像。

2. Why Use Case Studies in Psychology? | 心理学中为什么使用案例研究？

Psychologists turn to case studies when they want to explore something that is too complex or rare for experiments. For instance, you cannot ethically deprive a child of language just to see what happens, but you can study a real case where that occurred naturally.

当心理学家想要探索太复杂或太罕见而不适合实验的现象时，他们会转向案例研究。例如，你无法合乎伦理地剥夺一个孩子的语言环境来观察后果，但你可以研究一个自然发生的真实案例。

Case studies also allow researchers to challenge existing theories. One unusual case can show that a general rule does not apply to everyone, pushing science forward. They are particularly useful in clinical psychology to document unusual disorders and their treatment.

案例研究还能让研究者挑战现有理论。一个不寻常的案例就可以表明普遍规律并非对所有人都适用，从而推动科学进步。在临床心理学中，它们特别适用于记录罕见障碍及其治疗过程。

3. Key Features of a Case Study | 案例研究的主要特点

Every case study has certain core features that make it powerful:

每个案例研究都有一些使其强大的核心特征：

• Longitudinal Focus – they often follow the subject over weeks, months, or even years. / 纵向关注 – 通常对被试进行数周、数月甚至数年的跟踪研究。
• Multiple Data Sources – using interviews, diaries, medical records, and direct observation. / 多种数据来源 – 使用访谈、日记、医疗记录和直接观察。
• Individual-Centred – the spotlight is on a single case to uncover mechanisms that might be missed in group averages. / 以个体为中心 – 聚焦单个案例，揭示可能被群体平均值掩盖的机制。
• Rich Qualitative Data – words and descriptions are just as important as numbers. / 丰富的定性数据 – 文字描述和数字同样重要。

These features make case studies stand out from experiments, which aim for controlled, numerical data.

这些特点使案例研究区别于旨在获取受控数值数据的实验。

4. How to Conduct a Case Study: Step by Step | 如何进行案例研究：逐步指南

If you were a psychologist designing a case study, you would typically follow these steps:

如果你是一名心理学家设计案例研究，通常会遵循以下步骤：

Step 1: Identify a Research Question

Start with a clear question, such as ‘How does a traumatic brain injury affect memory?’

从一个清晰的问题开始，比如“创伤性脑损伤如何影响记忆？”

Step 2: Select Case(s)

Choose someone whose experience directly relates to your question – for example, a patient with a specific type of brain damage.

选择直接与你的问题相关的人——例如，一个患有特定类型脑损伤的病人。

Step 3: Collect Data

Use a mix of interviews, standardised tests, observations, and existing records to build a comprehensive file.

结合使用访谈、标准化测试、观察和现有记录来建立全面的档案。

Step 4: Analyse the Data

Look for patterns, links between events, and any changes over time.

寻找模式、事件之间的联系以及随时间的变化。

Step 5: Write the Report

Present the background, method, findings, and conclusions while protecting the subject’s identity.

呈现背景、方法、发现和结论，同时保护被试的身份。

5. Real-Life Example: The Case of Phineas Gage | 真实案例：菲尼亚斯·盖奇

Phineas Gage was a railroad worker who survived a horrific accident in 1848: an iron rod shot through his skull, destroying much of his frontal lobe. Miraculously, he could walk and talk afterwards, but his personality changed completely.

菲尼亚斯·盖奇是一名铁路工人，1848年在一场可怕的事故中幸存：一根铁棍穿透了他的头骨，破坏了大部分额叶。奇迹般地，他之后还能走路和说话，但他的性格完全变了。

Before the accident, Gage was responsible and polite. Afterward, he became impulsive, rude, and struggled to hold a job. This case provided early evidence that the frontal lobe governs personality and self-control, changing the course of neuroscience.

事故前，盖奇负责且有礼貌。事故后，他变得冲动、粗鲁，难以保住工作。这个案例提供了早期证据，证明额叶主导着个性和自控力，从而改变了神经科学进程。

Psychologists still debate whether the changes were as extreme as first reported, but the case remains a classic example of how one person’s tragedy can teach us about the brain.

心理学家仍争论这些变化是否像最初报道的那样极端，但这个案例仍是一个经典例子，说明一个人的悲剧如何教会我们关于大脑的知识。

6. Real-Life Example: Little Albert | 真实案例：小阿尔伯特

The ‘Little Albert’ experiment (1920) by John B. Watson and Rosalie Rayner is both a case study and an experiment. They conditioned a 9-month-old baby to fear a white rat by pairing it with a loud noise. Soon Albert generalised this fear to other furry objects like rabbits and even a Santa Claus mask.

约翰·B·华生和罗莎莉·雷纳在1920年进行的“小阿尔伯特”实验既是一个案例研究，也是一个实验。他们通过将白鼠与巨大噪音配对，使9个月大的婴儿对白鼠产生恐惧。很快，阿尔伯特将这种恐惧泛化到其他毛茸茸的物体，如兔子和甚至圣诞老人面具。

This case is taught worldwide to illustrate classical conditioning in humans. It raised serious ethical concerns because Albert was never de-conditioned, meaning his fear may have persisted. Despite its flaws, the study provides a dramatic example of how emotions can be learned.

这个案例在全世界被讲授，以说明人类的经典条件反射。它引发了严重的伦理关切，因为阿尔伯特从未被解除条件反射，这意味着他的恐惧可能持续下去。尽管有缺陷，该研究生动地展示了情绪是如何被习得的。

7. Practising Analysis: A Case of Memory Loss | 实战分析：一个记忆丧失案例

Imagine a 15-year-old named Mia who suddenly cannot form new memories after a viral infection. She remembers everything from before the illness but forgets new information within minutes. Doctors diagnose her with anterograde amnesia.

想象一个15岁的女孩米娅，在病毒感染后突然无法形成新记忆。她记得生病前的一切，但在几分钟内就会忘记新信息。医生诊断她患有顺行性遗忘症。

Let us practise analysing this case. First, what would you want to know? You might ask: Does she remember how to ride a bike or play an instrument? Can she learn new skills even if she doesn’t remember the learning session? These questions separate declarative memory (facts and events) from procedural memory (skills and habits).

让我们练习分析这个案例。首先，你想知道什么？你可能会问：她还记得如何骑自行车或弹奏乐器吗？即使她不记得学习过程，她能学会新技能吗？这些问题将陈述性记忆（事实和事件）与程序性记忆（技能和习惯）区分开来。

By comparing Mia to famous cases like H.M., who had a similar condition after surgery, psychologists built the theory that different memory systems exist in the brain. This shows how a single case can spark a whole research programme.

通过将米娅与著名案例H.M.（手术后患有类似病情）进行比较，心理学家建立了大脑中存在不同记忆系统的理论。这显示了一个单一案例如何激发整个研究项目。

8. Comparing Case Studies to Other Methods | 案例研究与其他方法的比较

Method	Case Study	Experiment	Survey
样本量 / Sample Size	Very small (often N=1)	Medium to large	Large
控制 / Control	Little to none	High	None on variables
数据 / Data	Mainly qualitative	Mainly quantitative	Quantitative/Qualitative
目的 / Purpose	Explore the unusual	Test cause-effect	Describe trends

Case studies are not designed to prove causes, but they can generate hypotheses that experiments then test. For example, Phineas Gage’s case suggested the frontal lobe’s role in personality; later experiments with animals confirmed and refined this idea.

案例研究并非旨在证明因果关系，但它们可以产生假设，随后由实验进行检验。例如，菲尼亚斯·盖奇的案例提示了额叶在个性中的作用；后来的动物实验证实并完善了这一想法。

9. Strengths of Case Studies | 案例研究的优势

Case studies offer unique advantages. They capture the complexity of real life—something a lab experiment often strips away. When you read a case study, you get a sense of the whole person in their environment, not just isolated variables.

案例研究具有独特的优势。它们捕捉了现实生活的复杂性——这往往是实验室实验所剥离的。当你阅读一个案例研究时，你会感受到整个人的生存环境，而不仅仅是孤立的变量。

They are indispensable for studying rare phenomena, like a person with a photographic memory that never fades, or a case of recovered memories after decades. Without case studies, these extraordinary stories would be lost to science.

对于研究罕见现象，它们不可或缺，比如一个永远不消退的摄影记忆者，或是几十年后恢复记忆的案例。没有案例研究，这些非凡的故事将无法被科学所了解。

Finally, case studies can challenge existing theories and lead to paradigm shifts. One contradictory case can force researchers to rethink what they thought was true.

最后，案例研究可以挑战现有理论并导致范式转变。一个矛盾的案例就能迫使研究者重新思考他们认为正确的东西。

10. Limitations of Case Studies | 案例研究的局限性

Despite their power, case studies have weak points. The most common criticism is they lack generalisability. Findings from one individual may not apply to others. Phineas Gage’s brain injury was so specific that we cannot assume all frontal lobe damage produces the same personality changes.

尽管案例研究很强大，但它们也有弱点。最常见的批评是缺乏可推广性。一个人的发现可能不适用于其他人。菲尼亚斯·盖奇的脑损伤如此特殊，以至于我们不能假设所有额叶损伤都会产生相同的性格改变。

Researcher bias is another concern. Because the psychologist often works closely with the subject, they may interpret data in a way that fits their expectations. Safeguards like using multiple observers and standardised tests can help, but the risk remains.

研究者偏见是另一个顾虑。因为心理学家通常与研究对象密切合作，他们可能会以符合自己预期的方式解释数据。使用多个观察者和标准化测试等保障措施可以有所帮助，但风险依然存在。

Memory and retrospective accounts can be unreliable. Case studies often rely on the subject’s recollection of past events, which may be flawed or incomplete.

记忆和回溯性叙述可能不可靠。案例研究常常依赖于研究对象对过去事件的回忆，这可能有缺陷或不完整。

---

11. Ethical Considerations in Case Studies | 案例研究中的伦理考量

When studying a unique individual, protecting their identity is crucial. Most case studies use pseudonyms (fake names) and avoid revealing details that could identify the person. The famous patient H.M., whose real name was Henry Molaison, was only revealed after his death.

在研究独特个体时，保护其身份至关重要。大多数案例研究使用化名，并避免透露可能识别该人的细节。著名病人H.M.，本名亨利·莫莱森，直到去世后才被公开。

Informed consent must be obtained where possible, and the subject should know they can withdraw at any time. If the person cannot give consent (e.g., due to brain damage), a guardian must approve. Additionally, the psychologist must weigh the benefits of the research against any distress the study might cause.

在可能的情况下必须获得知情同意，研究对象应知道他们可以随时退出。如果此人无法给予同意（例如因脑损伤），则必须由监护人批准。此外，心理学家必须权衡研究的益处与可能引起的任何痛苦。

Modern ethical guidelines, like those from the British Psychological Society, ensure today’s case studies are far more careful than the Little Albert or Gage accounts from a century ago.

现代伦理准则，如英国心理学会的准则，确保今天的案例研究比一个世纪前的小阿尔伯特或盖奇的叙述要谨慎得多。

12. Your Turn: DIY Case Study Project | 动手做：你自己的案例研究项目

Now it is your chance to think like a psychologist. Choose a famous figure from history, a character from a book, or a person you know well, and plan a mini case study. Write down: 1) what psychological question you want to explore, 2) what data you would collect, and 3) how you would analyse it while staying ethical.

现在轮到你像心理学家一样思考了。选择一个历史著名人物、书中的角色或你熟悉的人，规划一个小型案例研究。写下：1）你想探索什么心理问题，2）你会收集什么数据，3）在保持伦理的同时你将如何分析这些数据。

For example, if you chose a highly disciplined athlete, you might ask: ‘What motivates this person to maintain such a strict routine?’ You could interview them, observe their daily schedule, and read their diary entries. Then you could look for recurring themes like self-talk, goal setting, or fear of failure.

例如，如果你选择了一位高度自律的运动员，你可能会问：“是什么激励这个人保持如此严格的作息？”你可以采访他们，观察他们的日常时间表，并阅读他们的日记。然后你可以寻找反复出现的主题，比如自我对话、目标设定或对失败的恐惧。

Share your project idea with a classmate and discuss what makes it a good (or not so good) case study. Practising this way prepares you for real psychological analysis and builds skills you can use across all your subjects.

与同学分享你的项目构想，并讨论是什么使之成为一个好的（或不太好的）案例研究。以这种方式练习可以为你进行真正的心理分析做好准备，并培养你可以在所有学科中使用的技能。
