📚 Year 10 CIE Psychology: Case Study Practical Workout | Year 10 CIE 心理学：案例分析实战演练
Case studies are a core research method in psychology, enabling in-depth exploration of unique individuals or small groups. In Year 10 CIE Psychology, you need to understand how to analyse and evaluate case studies critically. This practical workout will guide you through famous examples, ethical issues, and step-by-step analysis techniques to sharpen your exam skills.
案例研究是心理学中的核心研究方法，能够深入探索独特的个体或小群体。在 Year 10 CIE 心理学中，你需要掌握如何批判性地分析与评估案例研究。本次实战演练将通过经典案例、伦理议题和逐步分析技巧，帮助你提升考试技能。
1. Introduction to Case Studies in Psychology | 心理学案例研究简介
A case study is a detailed investigation of a single person, group, or event. Unlike experiments, it gathers rich qualitative data from multiple sources, such as interviews, observations, and psychological tests.
案例研究是对单一个人、群体或事件的详细调查。与实验不同，它通过访谈、观察和心理测验等多种来源收集丰富的定性资料。
Psychologists often use case studies when studying rare phenomena or when ethical constraints prevent experimental manipulation, as seen in cases of brain injury or extreme deprivation.
心理学家通常在研究罕见现象或伦理限制阻止实验操控时使用案例研究，例如脑损伤或极度剥夺的案例。
2. The Case Study Method | 案例研究方法
The case study method typically involves longitudinal data collection, triangulation of evidence, and idiographic analysis. Researchers gather material over an extended period to trace development and change.
案例研究方法通常涉及纵向数据收集、证据三角验证和个体化分析。研究者长时间收集材料，以追踪发展和变化。
Triangulation uses multiple sources — such as interviews with family, medical records, and direct observations — to cross-validate findings and increase reliability.
三角验证利用多种来源（如家属访谈、病历和直接观察）来交叉验证发现，提高可靠性。
3. Ethical Considerations | 伦理考量
When working with case studies, psychologists must protect participant confidentiality, obtain informed consent, and avoid psychological harm. Anonymity is often maintained by using initials or pseudonyms, like 'H.M.' or 'Genie'.
在进行案例研究时，心理学家必须保护参与者隐私、获取知情同意并避免心理伤害。通常通过使用姓名缩写或化名（如 'H.M.' 或 'Genie'）来保持匿名。
Special care is needed when participants are vulnerable, such as children or those with cognitive impairments. In the case of Genie, ethical debates centred on the balance between research and care.
当参与者为弱势群体（如儿童或认知障碍者）时，需要特别谨慎。在吉妮案例中，伦理争议集中在研究与照护之间的平衡。
4. Case Study: Phineas Gage | 案例分析：菲尼亚斯·盖奇
Phineas Gage was a railway worker who survived an iron rod passing through his frontal lobe in 1848. His personality dramatically changed, providing early evidence for brain localisation.
菲尼亚斯·盖奇是铁路工人，1848 年他幸存于一根铁棍穿过其额叶的事故。他的人格发生了巨大变化，为大脑功能定位提供了早期证据。
Before the accident, Gage was described as responsible and polite; afterwards, he became impulsive and profane. This case study is a classic example of how the frontal lobe regulates behaviour.
事故前，盖奇被描述为负责且有礼貌；事故后，他变得冲动、满口脏话。这个案例是额叶如何调控行为的经典例证。
5. Case Study: Little Hans | 案例分析：小汉斯
Freud's study of 'Little Hans', a 5-year-old boy with a phobia of horses, was used to support the Oedipus complex theory. Data were collected through letters from the boy's father.
弗洛伊德对“小汉斯”的研究——一个害怕马的 5 岁男孩——被用来支持俄狄浦斯情结理论。数据通过男孩父亲的来信收集。
Freud interpreted Hans's fear as displaced anxiety from his unconscious desires. However, critics argue the interpretation was subjective and biased by the father's involvement.
弗洛伊德将汉斯的恐惧解释为无意识欲望的转移性焦虑。然而，批评者认为这种解释过于主观，并受父亲参与的影响。
6. Case Study: Genie | 案例分析：吉妮
Genie was a girl discovered at age 13 who had been isolated and abused, missing the critical period for language acquisition. Her case provided insights into language development and the effects of deprivation.
吉妮是一名 13 岁时被发现的女孩，她曾遭受隔离和虐待，错过了语言习得的关键期。她的案例为语言发展和剥夺效应提供了洞见。
Even after intensive rehabilitation, Genie never fully acquired grammar, supporting the critical period hypothesis. Ethical concerns arose when research goals conflicted with her welfare.
即使经过密集康复，吉妮也从未完全掌握语法，支持了关键期假说。当研究目标与其福祉冲突时，引发了伦理关切。
7. Case Study: Clive Wearing | 案例分析：克莱夫·韦林
Clive Wearing, a musician, developed severe anterograde and retrograde amnesia after a viral infection damaged his hippocampus. His case highlights the role of this brain area in memory.
音乐家克莱夫·韦林在病毒感染损伤其海马体后，出现了严重的顺行性和逆行性遗忘。他的案例突显了该脑区在记忆中的作用。
Wearing retains procedural memory (e.g., playing piano) but cannot form new episodic memories, demonstrating the distinction between memory types.
韦林保留了程序性记忆（如弹钢琴），但无法形成新的情景记忆，证明了记忆类型之间的区别。
8. Strengths of Case Studies | 案例研究的优点
Case studies provide rich, detailed qualitative data that can reveal the complexity of human behaviour. They are especially useful for generating hypotheses for future research.
案例研究提供丰富、详细的定性数据，能揭示人类行为的复杂性。它们对于为未来研究产生假设特别有用。
They allow investigation of rare conditions that cannot be ethically or practically recreated in a lab, such as severe neglect or specific brain injuries.
它们允许研究那些在伦理或实践上无法在实验室重现的罕见情况，如严重忽视或特定脑损伤。
9. Limitations of Case Studies | 案例研究的局限
Case studies often rely on retrospective data and memory, which can be unreliable. Researcher bias may shape the interpretation of findings, reducing objectivity.
案例研究常依赖于回顾性数据和记忆，这可能是不可靠的。研究者偏见可能塑造对发现的解释，降低客观性。
Findings from a single individual cannot be easily generalised to the wider population, limiting external validity.
基于单一个体的发现难以推广到更广泛的群体，限制了外部效度。
10. Analysing a Case Study Step-by-Step | 逐步分析案例
When approaching a case study in an exam, start by identifying the aim, method, and participant details. Then evaluate the findings, linking them to psychological theories.
在考试中分析案例时，首先确定研究目的、方法和参与者细节。然后评估发现，并将其与心理学理论联系起来。
Apply evaluation points: discuss ethics, validity, reliability, and sampling. Always use the P.E.E.L. structure — Point, Evidence, Explanation, Link — to build coherent paragraphs.
运用评价要点：讨论伦理、效度、信度和抽样。始终使用 P.E.E.L. 结构——论点、证据、解释、连接——构建连贯段落。
- Identify the type of case study: intrinsic, instrumental, or collective.
- 确定案例研究类型：内在型、工具型或集体型。
- Note the data collection methods: interviews, observations, standardised tests.
- 注意数据收集方法：访谈、观察、标准化测试。
- Consider the historical and cultural context.
