掌握案例分析是剑桥 Year 11 心理学取得成功的基石。本指南提供实战演练，将彻底改变你处理真实心理学情境的方式，从拆解复杂研究到构建高分考试答案。通过将理论框架与伦理推理融入每一步，你将学会像心理学家一样思考。
1. What is a Case Study in Psychology? | 心理学案例分析是什么？
A case study in psychology is an in-depth, detailed examination of a unique individual, group, or situation. It often combines multiple research methods such as interviews, observations, psychological tests, and archival records to build a rich portrait. Unlike experiments that manipulate variables, case studies retain the complexity and context of real life, making them especially useful for investigating rare phenomena.
心理学中的案例分析是对独特个体、群体或情境进行深入、详尽的检视。它通常结合多种研究方法，如访谈、观察、心理测验和档案记录，构建出丰富的全貌。与操控变量的实验不同，案例分析保留了现实生活的复杂性和背景，在调查罕见现象时尤其有用。
In the Cambridge syllabus, you are expected to recognise that case studies provide qualitative depth but may lack generalisability. You must be able to critique their validity, reliability, and ethical dimensions while extracting relevant psychological theories.
在剑桥教学大纲中，你应认识到案例分析提供了质性深度，但可能缺乏普遍性。你必须能够在提取相关心理学理论的同时，评价其效度、信度和伦理维度。
2. Core Theoretical Lenses: Biological, Cognitive and Social | 核心理论视角：生物、认知与社会
Every case study can be analysed through the three central approaches in Cambridge Psychology. The biological lens examines brain structures, neurotransmitters, hormones, and genetic predispositions. The cognitive perspective focuses on mental processes such as memory, attention, perception, and decision-making. The social approach explores how the presence of others, culture, norms, and group dynamics shape behaviour.
每个案例都可以通过剑桥心理学的三种核心途径来分析。生物视角考察脑结构、神经递质、激素和遗传倾向。认知视角聚焦于记忆、注意、知觉和决策等心理过程。社会取向则探讨他人的存在、文化、规范和群体动力如何塑造行为。
For instance, when reviewing a case of a patient with amnesia after brain injury, the biological lens would highlight damage to the hippocampus; the cognitive lens would describe deficits in encoding and retrieval; and the social lens might consider how the patient's identity and relationships are affected. Learning to switch between lenses is a key skill for exam questions that ask you to 'evaluate' a case study.
例如，在分析一例脑损伤后失忆的患者时，生物视角会强调海马体的损伤；认知视角会描述编码和提取方面的缺陷；而社会视角则可能考虑患者的身份认同和人际关系如何受到影响。学会在视角之间切换是应对要求你“评估”案例的考试题的关键技能。
3. Spotting Research Methods in a Case Description | 识别案例描述中的研究方法
Cambridge exam scenarios often embed research methods within a case narrative. You must quickly identify whether the study uses a longitudinal design, a cross-sectional snapshot, or a case history approach. Look for clues: repeated measures over years signal longitudinal work; comparisons between age groups at one point in time suggest cross-sectional design.
剑桥考试的题干常将研究方法嵌入案例叙述中。你必须迅速识别该研究采用的是纵向设计、横断快照还是个案史方法。寻找线索：多年重复测量表示纵向研究；在某一时间点比较不同年龄组则提示横断设计。
Common data collection techniques include structured or unstructured interviews, naturalistic or controlled observations, psychometric tests, and questionnaires. For each technique, consider its strengths (e.g., ecological validity from naturalistic observation) and limitations (e.g., social desirability bias in self-report). When the case mentions 'daily diaries' or 'CCTV footage', you are dealing with behavioural recording methods. Practice extracting these methods to gain immediate marks.
常见的数据收集技术包括结构化或非结构化访谈、自然观察或控制观察、心理测量测验和问卷。对每种技术，都要考虑其优势（例如，自然观察的生态效度）和局限（例如，自我报告中的社会赞许性偏差）。当案例提及“每日日记”或“监控录像”时，你面对的是行为记录法。练习提取这些方法以立即得分。
4. Ethical Considerations in Case Study Analysis | 案例分析中的伦理考量
Ethics are a fundamental component of any case study evaluation. You should automatically check for informed consent, confidentiality, right to withdraw, protection from psychological and physical harm, and debriefing. In the Cambridge syllabus, case studies of vulnerable participants (children, patients with mental disorders, prisoners) demand extra scrutiny regarding capacity to consent and privacy.
伦理是任何案例分析评估中的基本部分。你应自动审视是否具备知情同意、保密、退出权利、免于心理和身体伤害的保护以及事后解释。在剑桥大纲中，涉及弱势参与者（儿童、精神障碍患者、囚犯）的案例需要特别审查其同意能力和隐私保护。
A powerful drill is to ask: 'If I were a member of an ethics committee reviewing this case, what would I approve or reject?' This mindset helps you generate balanced arguments. For example, in a case study of a teenage anorexic patient, the detailed personal history is valuable for treatment but risks identification. Always link ethical issues back to the specific features of the case rather than giving generic statements.
一个有效的练习是问自己：“如果我是伦理审查委员会的成员，我会批准或驳回哪些内容？”这种心态有助于你提出平衡的论点。例如，在一例青少年厌食症患者的案例中，详细的个人史对治疗有价值，但存在身份暴露的风险。始终将伦理问题与案例的具体特征联系起来，而不是给出笼统的陈述。
5. The PEE Structure for Case Study Responses | 案例分析回答的 PEE 结构
The Point-Evidence-Explanation (PEE) framework is the gold standard for structuring your written answers. Start with a clear Point that directly addresses the question. Next, present Evidence from the case study — a specific detail, quotation, or statistic. Finally, Explain how this evidence supports your point, linking it to psychological concepts or theories.
观点-证据-解释（PEE）框架是构建书面答案的黄金标准。以直接回应问题的清晰观点（Point）开头。接着，呈现来自案例的证据（Evidence）——具体细节、引文或统计数据。最后，解释（Explain）该证据如何支持你的观点，并联系到心理学概念或理论。
For example, if asked why a child in a case study shows separation anxiety, your PEE could be: (Point) The child's behaviour aligns with Bowlby's attachment theory. (Evidence) The case reports that the mother left for a long hospitalisation when the child was 18 months old. (Explanation) This separation during the critical period likely disrupted the formation of a secure internal working model, leading to clingy and anxious behaviour now. Practice writing PEE paragraphs for every sub-question in past paper case studies.
例如，若被问到某案例中的儿童为何表现出分离焦虑，你的 PEE 可以是：（观点）该儿童的行为符合鲍尔比的依恋理论。（证据）案例报告称母亲在孩子18个月大时因长期住院而离开。（解释）这一关键期内的分离可能干扰了安全内部工作模式的形成，导致当前粘人、焦虑的行为。针对往年试卷案例中的每一小题练习撰写 PEE 段落。
6. Drill Case 1: Memory – Patient KF | 案例演练 1：记忆 – 患者 KF
Patient KF suffered damage to his left parietal-occipital lobe after a motorcycle accident. Studies showed his short-term memory for visual information was severely impaired, while his auditory memory remained relatively intact. This case is a classic example used to challenge the unitary model of short-term memory and support the Working Memory Model.
患者 KF 在一次摩托车事故后左侧顶枕叶受损。研究显示，他对视觉信息的短时记忆严重受损，而听觉记忆相对完好。此案例是被用来挑战短时记忆单一模型、支持工作记忆模型的经典实例。
Apply the lenses: Biologically, damage to the parietal lobe explains the specific visual memory deficit. Cognitively, the findings suggest distinct slave systems (the visuo-spatial sketchpad was damaged, but the phonological loop was spared). Ethically, KF's identity was protected by using initials, and repeated testing may have caused fatigue — a risk that researchers needed to manage.
运用不同视角：生物学上，顶叶损伤解释了特定的视觉记忆缺陷。认知上，研究结果表明存在独立的附属系统（视觉空间画板受损，而语音回路完好）。伦理上，使用姓名首字母保护了 KF 的身份，而反复测试可能造成疲劳——这是研究者需把控的风险。
ry, and the consistency of findings across multiple testing sessions. This trains you to combine methodological evaluation with theoretical insight.
练习：在8分钟内写一个 PEE 段落，论证此案例是否可靠。考虑样本量（n=1）、损伤的独特性，以及多次测试结果的一致性。这能训练你结合方法学评价与理论洞见。
7. Drill Case 2: Obedience – Milgram's Study on Authority | 案例演练 2：服从 – 米尔格拉姆权威研究
Stanley Milgram's 1963 experiment is often presented as a case study of extreme obedience. Forty male volunteers were told they were taking part in a learning experiment and were instructed to administer increasing electric shocks to a 'learner' (a confederate) whenever a mistake was made. The finding that 65% of participants continued to the maximum 450 volts shocked the world.
斯坦利·米尔格拉姆 1963 年的实验常被当作极端服从的案例来呈现。四十名男性志愿者被告知参加一项学习实验，并被指令每当“学习者”（同谋）出错时就施加逐级增强的电击。65% 的参与者一直持续到最大 450 伏特的结果震惊了全世界。
When analysing, focus on the powerful situational factors: the prestigious Yale University setting, the presence of an authority figure in a lab coat, and the incremental nature of the shocks. The social approach explains obedience through agency theory, where individuals shift responsibility to the authority. Biologically, the stress reactions (sweating, trembling) show the conflict between conscience and obedience. Critically, evaluate ethics: deception was extreme, and participants were visibly distressed, yet Milgram's thorough debriefing and follow-up surveys showed no long-term harm.
分析时要聚焦强大的情境因素：耶鲁大学的声誉、穿白大褂的权威人物在场，以及电击的渐进式递增。社会途径通过代理人理论解释服从，即个体将责任转移给权威。生物学上，应激反应（出汗、颤抖）展示了良知与服从之间的冲突。关键在于伦理评价：欺骗极端，参与者明显痛苦，但米尔格拉姆彻底的事后解释和后续调查显示无长期伤害。
8. Drill Case 3: Attachment – Ainsworth's Strange Situation | 案例演练 3：依恋 – 安斯沃思的陌生情境
Mary Ainsworth's Strange Situation procedure was a short, structured observational case study of infant-caregiver attachment patterns. Infants aged 12-18 months were exposed to a series of separations and reunions with their mother and a stranger. Based on their responses, infants were classified as securely attached (Type B), insecure-avoidant (Type A), or insecure-ambivalent (Type C).
玛丽·安斯沃思的陌生情境程序是一项对婴儿与照料者依恋模式进行的短期、结构化观察案例研究。12-18 个月大的婴儿经历一系列与母亲和陌生人的分离与重聚。根据反应，婴儿被分为安全型（B 型）、不安全-回避型（A 型）或不安-矛盾型（C 型）。
To write an evaluative answer, use cross-cultural evidence: for instance, German infants showed higher rates of avoidant behaviour, which may reflect cultural emphasis on early independence
