1. What Is a Case Study? | 什么是案例研究？
A case study is an in‑depth investigation of a single individual, group or event. Unlike large-scale surveys or experiments, it focuses on the unique circumstances of one 'case' in great detail, often using multiple methods such as interviews, observations and psychological tests. The aim is not to generalise directly to a population but to build a comprehensive picture that can reveal underlying psychological processes, sometimes leading to new theories or hypotheses.
案例研究是对单一个体、群体或事件的深入调查。与大规模调查或实验不同，它极度关注一个“案例”的独特处境，通常使用访谈、观察和心理测验等多种方法。其目的并非直接向总体推广，而是构建一个全面的图景，揭示潜在的心理过程，有时还能引出新的理论或假设。
2. Key Features of a Case Study | 案例研究的关键特征
A hallmark of case studies is their longitudinal nature – they often track the individual over a long period, sometimes years. Data collection is flexible and holistic, gathering both quantitative data (e.g. test scores, physiological measures) and qualitative data (e.g. diary entries, therapy transcripts). This triangulation of sources helps to enrich the analysis and improve validity. The researcher may develop a close rapport with the participant, which can yield deeper insights but also introduces potential researcher bias.
案例研究的一个标志是其纵贯性质——它们往往在很长一段时间内追踪个体，有时长达数年。数据收集灵活且整体化，既收集量化数据（如测验分数、生理指标），也收集质化数据（如日记、治疗记录）。这种多元来源的三角验证有助于丰富分析、提高效度。研究者可能与参与者建立密切关系，这能产生更深的洞见，但也可能引入研究者偏见。
3. The Process of Conducting a Case Study | 进行案例研究的过程
Psychologists typically start by defining a research question that emerges from an unusual condition or a gap in the literature. They then select a case that exemplifies the phenomenon. Data is gathered through multiple channels – perhaps interviewing family members, administering cognitive tests and reviewing medical records. All information is organised into a compelling narrative, and themes or patterns are extracted using content analysis. Finally, the researcher forms tentative conclusions, often comparing the findings with existing theories and suggesting directions for future research.
心理学家通常先从一个罕见状况或文献空白中确定研究问题，然后遴选出能体现该现象的案例。通过多种渠道收集数据——或许访谈家属、实施认知测验、查阅医疗记录。所有信息被整合成一个连贯的叙述，再用内容分析法提取主题或模式。最后，研究者得出暂定结论，常将结果与现有理论对比，并提出未来研究方向。
4. Case Studies vs Other Research Methods | 案例研究与其他研究方法的比较
Case studies differ markedly from experimental methods. While experiments isolate and manipulate independent variables to establish cause‑and‑effect, case studies describe the natural unfolding of events without deliberate intervention. Compared to questionnaires, which can access large samples but give superficial data, case studies offer depth. However, they lack the replicability of controlled laboratory studies. This table summarises key comparisons:
案例研究与实验方法显著不同。实验隔离并操纵自变量以建立因果关系，而案例研究则在无刻意干预的情况下描述自然展开的事件。与能触及大样本但只能提供表面数据的问卷相比，案例研究提供了深度。然而，它们缺乏受控实验室研究的可复制性。下表概括了主要对比：
| Feature / 特征 | Case Study / 案例研究 | Experiment / 实验 | Survey / 问卷 |
|---|---|---|---|
| Depth / 深度 | Very high / 极高 | Moderate / 中等 | Low / 低 |
| Generalisability / 可推广性 | Low / 低 | High (with random sampling) / 高（随机抽样） | High / 高 |
| Causation / 因果关系 | Cannot establish / 无法确定 | Can establish / 可以确定 | Cannot establish / 无法确定 |
| Researcher control / 研究者控制 | Minimal / 最小 | High / 高 | Low / 低 |
5. Strengths of Case Studies | 案例研究的优势
One major strength is ecological validity – the study occurs in real‑life contexts, so behaviour is naturally occurring. Case studies are indispensable for investigating rare phenomena, such as profound memory loss (like Clive Wearing) or unique brain injuries, which would be unethical or impossible to reproduce experimentally. The rich, qualitative data can challenge established theories; for instance, the case of Genie prompted debate about the critical period hypothesis in language development. Furthermore, the detailed narrative often generates new hypotheses that can be tested later with larger samples.
主要优势之一是生态效度——研究在真实情境中进行，行为是自然发生的。案例研究对于探究罕见现象不可或缺，比如严重记忆丧失（如克莱夫·韦林）或独特脑损伤，这些若用实验再现则完全不道德或不可能。丰富的质性数据可以挑战既有理论；例如，吉妮案例引发了关于语言发展关键期假说的辩论。此外，详尽的叙述往往催生新假说，日后可用更大样本加以检验。
6. Limitations of Case Studies | 案例研究的局限性
Case studies are often criticised for poor generalisability because a single individual cannot represent a whole population. Subjectivity is another concern – the researcher’s interpretation of qualitative data can be influenced by personal bias, especially when they build a close relationship with the participant. Retrospective data, relied upon in many cases, can suffer from memory distortions. In addition, the method typically cannot establish cause‑and‑effect; observed changes could be due to coincidental factors or natural development rather than the specific variable of interest.
案例研究常因推广性差而受批评，因为单一个体无法代表整个群体。主观性是另一担忧——研究者对质性数据的解读可能受到个人偏见影响，尤其是当他们与参与者建立密切关系时。许多案例依赖回溯性数据，可能受记忆扭曲的困扰。此外，该方法通常无法确立因果关系；观察到的变化可能源于偶发因素或自然成长，而非特定的关注变量。
7. Ethical Considerations in Case Studies | 案例研究的伦理考量
Ethical challenges are particularly acute in case studies. Protecting anonymity is hard when a case is well‑known or medically unique; for example, the true identity of the famous amnesic patient H.M. (Henry Molaison) was revealed only after his death. Informed consent can be problematic when the participant is a child, as with Little Hans, or has cognitive impairments. Researchers must avoid exploiting participants for academic gain and should debrief thoroughly. In the Genie case, serious ethical breaches occurred when the research team prioritised data collection over the child’s welfare, highlighting the need for rigorous ethical review.
案例研究中的伦理挑战尤为严峻。当案例为人熟知或具有医学独特性时，很难保护匿名性；例如，著名失忆症患者 H.M.（亨利·莫莱森）的真实身份直到他去世后才被披露。当参与者为儿童（如小汉斯）或有认知障碍时，知情同意会很棘手。研究者必须避免为了学术利益而剥削参与者，并应彻底进行事后解释。在吉妮案例中，研究团队将数据采集置于儿童福祉之上，出现了严重伦理违规，凸显了严格伦理审查的必要性。
8. A Step‑by‑Step Guide to Analysing a Case Study | 案例分析分步指南
When faced with a case study in your exam, break down your analysis into clear, structured steps. Begin by identifying the aim and the background of the case. Next, describe the methods used to gather data: were interviews, observations or standardised tests employed? Note the findings, distinguishing between factual observations and the researcher’s interpretations. Then evaluate the strengths and weaknesses of the approach, linking each point to methodological concepts like validity, reliability and generalisability. Finally, comment on ethical issues and suggest how future research might build on the case. This structure will ensure your answer is comprehensive and marks are maximised.
当你在考试中遇到案例研究时，把分析拆分成清晰的结构化步骤。首先识别研究目的和案例背景。接着描述收集数据的方法：是否使用了访谈、观察或标准化测验？记录发现，区分事实性观察与研究者的诠释。然后评估该方法的优势与弱点，把每一点都联系到效度、信度和可推广性等方法论概念上。最后评论伦理问题，并建议未来研究如何基于该案例展开。这一结构能确保你的答案全面，分数最大化。
9. Applied Example: The Case of Genie | 应用实例：吉妮案例
Genie was a girl discovered at age 13 who had been kept in extreme social isolation and subjected to severe deprivation. The case presented a tragic 'natural experiment' to investigate whether there is a critical period for language acquisition. Researchers, including Curtiss (1977), worked intensively with Genie using a combination of observations, language tests and therapeutic sessions. Despite the efforts, Genie never gained full grammatical competence, which supported the idea that language learning is time‑sensitive. However, the study was complicated by inconsistent care and the ethical disputes over the research team’s dual role as scientists and caregivers.
吉妮是一名在 13 岁才被发现的女孩，她一直处于极端的社会隔离和严重剥夺之中。这个案例提供了一个悲剧性的“自然实验”，以探讨语言习得是否存在关键期。以 Curtiss（1977）为首的研究者结合观察、语言测验和治疗课程对吉妮进行了密集工作。尽管努力种种，吉妮从未获得完全的语法能力，这支持了语言学习具有时间敏感性的观点。然而，照护前后不一以及研究团队同时扮演科学家与照顾者的角色所引发的伦理争议，使该研究变得复杂。
10. Analysing the Genie Case Like a Psychologist | 像心理学家一样分析吉妮案例
When analysing the Genie case, start with the aim: to study the impact of early deprivation on language development. Methods included repeated testing, naturalistic observation and audio recordings. A strength is the depth of insight into a condition that cannot be replicated artificially, giving rich qualitative evidence. However, the case lacks generalisability because of its uniqueness. The relationship between researchers and Genie likely introduced researcher bias, and the study encountered severe ethical problems: Genie’s privacy was impossible to protect, and the line between research and therapy was blurred. In your commentary, always link these points to psychological concepts, such as 'critical period hypothesis', 'attachment theory' and 'researcher effect'.
分析吉妮案例时，从研究目的入手：探讨早期剥夺对语言发展的影响。所使用的方法包括重复测试、自然观察和录音。优点在于能深入洞察一种无法人为再现的状况，提供了丰富的质性证据。然而，该案例因其独特性而缺乏推广性。研究者与吉妮的关系很可能引入了研究者偏见，且该研究遭遇了严重的伦理问题：吉妮的隐私无法得到保护，研究角色与治疗角色间的界限模糊不清。在你的评论中，务必把这些要点联系到心理学术语上，如“关键期假说”“依恋理论”和“研究者效应”等。
11. Applied Example: The Case of Phineas Gage | 应用实例：菲尼亚斯·盖奇案例
In 1848, Phineas Gage suffered a horrific accident when an iron rod pierced through his skull, destroying much of his left frontal lobe. Miraculously, he survived, but his personality changed dramatically – from a responsible, mild‑mannered foreman to a profane and impulsive man, as reported by his doctor, John Harlow. This case was pivotal in suggesting that the frontal lobes are involved in personality regulation and executive functions. Although not a planned case study, it became one of the most cited examples in neuroscience, illustrating how a single case can reshape our understanding of brain‑behaviour relationships.
1848 年，菲尼亚斯·盖奇遭遇可怕事故，一根铁棍刺穿其颅骨，损毁了大部分左额叶。不可思议的是他活了下来，但人格发生了剧变——据他的医生约翰·哈洛报道，他从一个负责任、脾气温和的工头变成了满口脏话、冲动行事的人。这个案例在提示额叶参与人格调节和执行功能方面具有里程碑意义。尽管并非有计划进行的案例研究，它却成为神经科学中被引用最多的例子之一，说明单个案例如何重塑我们对脑与行为关系的认识。
12. Tackling Case Study Questions in Your OCR Exam | 在 OCR 考试中应对案例研究问题
OCR exam questions on case studies often ask you to 'outline' a case, 'evaluate the method' or 'discuss ethical issues'. Always use the PEE structure (Point, Evidence, Explain) and bring in methodological language: ecological validity, longitudinal design, sample bias, inter‑rater reliability, etc. When asked to suggest improvements, consider how another method (like a questionnaire or experiment) could address a limitation, but also acknowledge what would be lost in depth. Practise by summarising the key details of classic cases (Genie, Phineas Gage, Clive Wearing) and by writing timed evaluation paragraphs. The more you practise, the more naturally you will connect evidence to theory under exam conditions.
OCR 考试中有关案例研究的问题常要求你“概述”案例、“评估该方法”或“讨论伦理问题”。务必使用 PEE 结构（观点、证据、解释），并引入方法学术语：生态效度、纵向设计、样本偏差、评分者信度等。当被要求提出改进建议时，思考另一种方法（如问卷或实验）如何解决某项局限，但也要指出会在深度上失去什么。通过总结经典案例（吉妮、菲尼亚斯·盖奇、克莱夫·韦林）的关键细节，并计时练习写评估段落来提高。练习得越多，你在考试情境下把证据与理论联系起来就会越自然。
