📚 Case Study Workout for Year 7 CIE Psychology | 七年级CIE心理学：案例分析实战演练
Case studies are one of the most fascinating research methods in psychology. They allow you to dive deep into the life of a single person, a small group, or a unique event to uncover psychological truths that surveys and experiments might miss. For Year 7 CIE Psychology students, learning to analyse case studies is not only a key skill for exams but also a fantastic way to see how psychological theories apply to real human stories. This article will guide you step by step through the process of understanding, evaluating and writing about case studies with plenty of practice along the way.
案例研究是心理学中最吸引人的研究方法之一。它让你能够深入探究某一个人、一个小群体或一个独特事件的细节，去发现问卷调查和实验可能错过的心理学真相。对于学习 CIE 七年级心理学的同学来说，学会分析案例研究不仅是应对考试的关键技能，更是一种绝佳的方法，让你亲眼看到心理学理论如何应用于真实的人类故事。本文将一步步带你走过理解、评估和撰写案例研究的过程，并穿插大量实践练习。
1. What Is a Case Study? | 什么是案例研究？
A case study is an in‑depth investigation of an individual, group or specific situation. The aim is to gather detailed information, often over a long period, to understand behaviour, thoughts and emotions in a real‑world context. Unlike experiments that test many people under controlled conditions, a case study focuses on the richness of a single case.
案例研究是对一个人、一个群体或一个特定情境的深入调查。其目的通常是长期收集详细信息，在真实世界的背景下理解行为、思维和情感。与在受控条件下测试许多人的实验不同，案例研究聚焦于某个个案的丰富细节。
Researchers may use interviews, observations, diaries and psychological tests to collect data. For example, a psychologist might study a child with an extraordinary memory to learn about how memory works.
研究者可能会采用访谈、观察、日记和心理测验来收集数据。例如，心理学家可能研究一个具有非凡记忆力的孩子，以探索记忆的运作方式。
2. Why Psychologists Use Case Studies | 心理学家为何使用案例研究？
Psychologists turn to case studies when they want to explore rare or unusual phenomena that cannot be recreated in a lab. A person with a unique brain injury, a feral child or someone with a rare phobia would be impossible to study through large‑scale experiments. Case studies give voice to these exceptional stories.
当心理学家希望探究无法在实验室里复制的罕见或不寻常现象时，就会采用案例研究。有独特脑损伤的人、野孩子或患有罕见恐惧症的人，是无法通过大规模实验来研究的。案例研究让这些特殊的故事得以被倾听。
Case studies are also useful for generating hypotheses. The detailed observations made in a single case can spark ideas that are later tested with larger samples. In therapy, a case study helps track an individual’s progress and refine treatment.
案例研究还有助于提出假设。在单个案例中做出的细致观察可能激发新的想法，供日后在更大样本中检验。在治疗中，案例研究有助于追踪个人的进展并完善治疗。
3. Key Characteristics of Case Studies | 案例研究的主要特征
Case studies are typically longitudinal, meaning they follow the subject over time — sometimes for months or years. This helps psychologists see how behaviour changes or develops. They also use triangulation, which means gathering data from multiple sources (e.g. interviews, school reports, family observations) to build a fuller and more reliable picture.
案例研究通常是纵向的，即长时间追踪研究对象——有时长达数月甚至数年。这有助于心理学家观察行为如何变化或发展。它们还会采用三角验证，也就是从多个来源收集数据（如访谈、学校报告、家庭观察），从而构建出更完整、更可靠的图景。
Most case studies are idiographic, focusing on the unique qualities of the individual rather than trying to find universal laws. The findings are presented as rich, narrative descriptions that capture the complexity of real life.
大多数案例研究都是个案式的，关注个体的独特品质，而不是试图寻找普遍规律。研究结果通常以丰富的叙事描述呈现，捕捉现实生活的复杂性。
4. How to Analyse a Case Study Step by Step | 如何分步分析案例研究
Step 1: Read the case carefully and highlight key facts — age, background, unusual behaviours, events. Make sure you understand what is happening before you start linking it to psychology.
第一步：仔细阅读案例，标出关键事实——年龄、背景、异常行为、事件。在开始将其与心理学知识联系起来之前，确保你理解了正在发生的事情。
Step 2: Identify the psychological issues. Is the person showing signs of anxiety? Attachment problems? Memory deficits? Pick out the behaviours that psychologists would be interested in.
第二步：识别心理问题。这个人是否表现出焦虑迹象？依恋问题？记忆缺陷？挑出心理学家会感兴趣的行为。
Step 3: Choose an appropriate theory or concept. For example, if someone is afraid of dogs, you might use classical conditioning from the behaviourist approach. If a child is struggling to make friends, Bowlby’s attachment theory could help.
第三步：选择一个适当的理论或概念。例如，如果有人害怕狗，你可以用行为主义方法中的经典条件作用来解释。如果一个孩子难以交朋友，鲍尔比的依恋理论可能有用。
Step 4: Apply the theory to the specifics of the case. Explain how the theory accounts for what you have observed. Use phrases like ‘This can be explained by…’ or ‘According to the theory, her behaviour is the result of…’
第四步：将理论应用于案例的具体细节。解释理论如何说明你所观察到的现象。可以使用这样的表述：”这可以用……来解释”或”根据该理论，她的行为是……的结果”。
Step 5: Evaluate the case study method itself. Consider the strengths (depth, ecological validity) and weaknesses (subjectivity, lack of generalisability) of using a single case to draw conclusions.
第五步：评估案例研究方法本身。思索只根据单个案例得出结论的优势（深度、生态效度）和弱点（主观性、缺乏普遍性）。
5. Classic Case Study: Little Albert | 经典案例研究：小阿尔伯特
In 1920, John B. Watson and Rosalie Rayner conducted a famous (and ethically questionable) case study of an 11‑month‑old boy called ‘Little Albert’. Albert initially showed no fear of a white rat. The researchers then paired the rat with a loud, frightening noise. After several pairings, Albert cried and tried to crawl away whenever the rat appeared. His fear generalised to other furry objects like a rabbit, a fur coat and even a Santa Claus beard.
1920年，约翰·华生和罗莎莉·雷纳对一个名叫”小阿尔伯特”的11个月大男婴进行了一项著名（但伦理上有争议）的案例研究。起初，阿尔伯特对小白鼠没有恐惧。研究者随后将毛茸茸的动物与一个巨大的可怕噪声配对呈现。几次之后，只要小白鼠出现，阿尔伯特就会哭闹着试图爬开。他的恐惧泛化到了其他带毛的物品上，如兔子、皮毛大衣，甚至圣诞老人的胡子。
Analysis through classical conditioning: the white rat was initially a neutral stimulus (NS). The loud noise was an unconditioned stimulus (UCS) that naturally produced fear (UCR). After pairing, the rat became a conditioned stimulus (CS) producing a conditioned fear response (CR). This case is often used to illustrate how phobias might be learned.
通过经典条件作用分析：小白鼠最初是中性刺激（NS）。巨大噪声是非条件刺激（UCS），自然引起恐惧（UCR）。配对之后，小白鼠变成了条件刺激（CS），引起条件性恐惧反应（CR）。这个案例常被用来说明恐惧症可能是如何习得的。
However, the case had only one participant, so we cannot be sure the findings apply to all children. The study also broke modern ethical rules: it caused distress and no attempt was made to remove the conditioned fear afterwards.
然而，该案例只有一个参与者，所以我们无法确定结果是否适用于所有儿童。这项研究也违反了现代伦理准则：它造成了痛苦，事后也没有尝试消除条件化的恐惧。
6. Classic Case Study: Genie the Wild Child | 经典案例研究：野孩子吉妮
Genie was a girl discovered in 1970 at the age of 13. She had been kept in extreme isolation and abuse by her father for most of her life. When found, she could barely walk, could not speak, and was severely malnourished. Psychologists saw her as an opportunity to study language development and the effects of early deprivation.
吉妮是一名在1970年被发现的13岁女孩。她一生中大部分时间都被父亲极端隔离和虐待。被发现时，她几乎不能走路，不会说话，并且严重营养不良。心理学家将她视为研究语言发展和早期剥夺影响的机会。
Researchers worked with Genie intensively. She learned many words and could communicate through gestures, but she never acquired the grammar typical of a normally developing child. This case supported the idea of a ‘critical period’ for language — a window in early childhood when language must be learned, or it may never be fully acquired.
研究者对吉妮进行了密集训练。她学会了许多单词，并能用手势交流，但她从未获得正常发育儿童那样的语法能力。这个案例支持了语言发展”关键期”的假说——童年早期是学习语言的一个时间窗口，一旦错过，语言就可能永远无法完全习得。
Genie’s case also raised serious ethical concerns. The researchers may have prioritised scientific data over her well‑being, and she experienced multiple changes in care. Confidentiality was hard to maintain. Today, such a case would be handled with much stricter safeguards.
吉妮的案例也引发了严重的伦理担忧。研究者可能将科学数据置于她的福祉之上，而且她经历了多次看护变动。保密性也很难维持。今天，这种案例会在更为严格的保护措施下处理。
7. Ethical Issues in Case Studies | 案例研究中的伦理问题
Informed consent is often a challenge. When the participant is a child or someone with learning difficulties, researchers must obtain consent from a parent or guardian. Even then, the participant should be told what the study involves in a way they can understand.
知情同意常常是一个挑战。当参与者是儿童或有学习困难的人时，研究者必须获得父母或监护人的同意。即便如此，也应以参与者能理解的方式告诉他们研究涉及的内容。
Confidentiality must be protected. In famous case studies like Genie or Little Albert, real names were hidden, but details of their lives could still lead to identification. Psychologists today keep data anonymous and store it securely.
必须保护隐私。在吉妮或小阿尔伯特等著名案例研究中，虽然真名被隐藏，但生活细节仍可能使人被认出。如今，心理学家会将数据匿名化并安全保存。
The right to withdraw means participants should be free to leave a study at any time without negative consequences. In long‑term case studies, this can be tricky if the researcher has built a close relationship with the participant. Protecting the participant from harm is the most important rule of all.
退出权意味着参与者可以随时退出研究而不承担负面后果。在长期的案例研究中，如果研究者与参与者建立了密切关系，这可能会变得棘手。保护参与者免受伤害是所有规则中最重要的一条。
8. Evaluating a Case Study: Strengths and Weaknesses | 评估案例研究：优势与局限
Strengths
Case studies provide tremendous detail and depth, giving researchers a thorough understanding of the person’s life. Because they occur in real‑world settings, they have high ecological validity — the behaviour observed is genuine and not artificial. They are sometimes the only ethical way to study very rare conditions, like a unique brain injury.
优势
案例研究提供了极为丰富的细节和深度，让研究者能全面了解一个人的生活。由于研究发生在真实世界环境中，因此具有较高的生态效度——观察到的行为是真实而非人造的。有时，这是研究非常罕见的状况（如特殊脑损伤）的唯一合乎伦理的方式。
Weaknesses
The biggest drawback is that the results from one individual cannot be easily generalised to the wider population. The researcher’s own opinions may also influence the interpretation of data, leading to subjectivity. Moreover, case studies often rely on memories and self‑reports, which may be inaccurate. Replicating the exact conditions of a case study is usually impossible.
局限
最大的缺点是一个人的结果很难推广到更广泛的人群。研究者自己的观点也可能影响数据的解释，导致主观性。此外，案例研究往往依赖记忆和自我报告，而这些可能并不准确。通常无法严格复制一个案例研究的确切条件。
9. Practice Case Study: The Curious Case of Alex | 实战案例：亚历克斯的好奇案例
Read the case below and try to apply what you have learned.
Alex is a 12‑year‑old boy who moved to a new school six months ago. Since the move, he has become extremely quiet in class and refuses to speak to most classmates, though he chats happily at home with his parents and one close neighbour his own age. Teachers report that he often looks anxious when asked a question and sometimes covers his ears during loud group activities. His family background is warm and supportive, but Alex’s father lost his job shortly before the move, causing tension at home. Alex used to enjoy drama club, but now avoids it entirely.
阅读下面的案例，尝试应用你学过的知识。
亚历克斯是一名12岁男孩，六个月前转学到一所新学校。自从转学后，他在课堂上变得极度安静，拒绝与大多数同学说话，但在家里与父母和一个同龄的邻居小伙伴聊天时却很愉快。老师们报告说，当被提问时他常常显得焦虑，有时在嘈杂的集体活动中会捂住耳朵。他的家庭背景温暖且支持，但亚历克斯的父亲在搬家前不久失业了，导致家庭气氛紧张。亚历克斯以前很喜欢戏剧社，但现在完全回避了。
Your analysis tasks:
你的分析任务：
1. Identify two psychological issues Alex might be experiencing. (Examples: social anxiety, selective mutism, adjustment disorder.)
2. Choose one theory to explain Alex’s behaviour — consider classical conditioning, attachment theory or the social learning theory of phobias. Explain how the theory fits the details.
3. Suggest one strength and one weakness of using a case study approach to understand Alex.
4. List one ethical consideration a psychologist should keep in mind if they studied Alex in depth.
1. 指出亚历克斯可能存在的两个心理问题。（例如：社交焦虑、选择性缄默、适应障碍。）
2. 选择一个理论来解释亚历克斯的行为——考虑经典条件作用、依恋理论或恐惧症的社会学习理论。说明理论如何契合细节。
3. 提出使用案例研究方法来理解亚历克斯的一个优势和一个局限。
4. 列出心理学家若深入研究亚历克斯应牢记的一项伦理考量。
Sample explanation using classical conditioning: Alex may have associated the new school (neutral stimulus) with the stress of the move and his father’s unemployment (unconditioned stimulus), leading to anxiety (unconditioned response). Now the school alone is a conditioned stimulus that triggers anxiety and mutism (conditioned response). Avoidance of drama club is a behavioural response that reduces anxiety, negatively reinforcing his quietness.
使用经典条件作用的示例解释：亚历克斯可能将新学校（中性刺激）与搬家压力、父亲失业（非条件刺激）联系起来，导致焦虑（非条件反应）。如今学校本身成了条件刺激，引发焦虑和缄默（条件反应）。回避戏剧社是一种减少焦虑的行为反应，对他而言起到了负强化的作用，加剧了他的沉默。
10. Tips for Writing Case Study Answers in Exams | 考试中撰写案例研究答案的技巧
Start your answer by briefly summarising the case to show you have understood it. Then signal the theory you will use: ‘This case can be understood through the lens of…’ Always link theory points directly to the individual’s behaviour. Do not just describe the theory; show how it explains the specific details given.
开始答题时，简要概述案例以表明你已经理解。然后指明你将使用的理论：”这个案例可以通过……的视角来理解。”始终将理论要点直接与个体的行为联系起来。不要只描述理论，要展示它如何解释给出的具体细节。
Remember to evaluate. Examiners love to see ‘However, a limitation of this case study is…’ or ‘Because this is a single case, it is difficult to…’ You can also mention what would make the study stronger, such as collecting data from more sources or using standardised questionnaires alongside observations.
记得进行评估。考官喜欢看到”然而，这个案例研究的一个局限是……”或者”由于这是一个单个案例，很难……”你也可以提及什么能使研究更可靠，比如从更多来源收集数据，或在观察的同时使用标准化问卷。
Keep your answer focused and avoid storytelling. Every sentence should serve a purpose — describing, explaining, applying or evaluating. Use psychological keywords like ‘generalisation’, ‘triangulation’, ‘subjective’ and ‘operant conditioning’ to show your vocabulary.
答案要聚焦，避免流水账。每个句子都应有一个目的——描述、解释、应用或评估。使用心理学术语，如”普遍性”、”三角验证”、”主观的”和”操作条件作用”，以展示你的词汇量。
11. Key Terms to Remember | 记住的关键术语
Here are some essential terms you might use in case study questions:
以下是一些在案例研究问题中你可能用到的基本术语：
Longitudinal — a study that follows the same people over a period of time.
纵向研究 — 在一段时间内追踪同一批人的研究。
Triangulation — using multiple sources of data to improve credibility.
