欢迎来到这门针对 WJEC 12年级心理学课程中案例分析题目的精讲实战课。在 AS 课纲中，你不仅需要复述经典研究，还要将所学知识应用于新情境。案例研究既是一种研究方法，也是检验你对生物、社会、认知和发展心理学理解的跳板。本文提供了实战练习、分步分析框架和范例解答，帮助你从无从下笔到写出高分答案。

1. Understanding Case Studies in WJEC Psychology | 理解 WJEC 心理学中的案例研究

A case study is an in‑depth investigation of a single person, group or event. In WJEC assessments, you must be able to recognise a case study as a non‑experimental method, describe its features and evaluate its use. Unlike experiments, case studies do not manipulate an independent variable; instead, they collect rich, qualitative data over a period of time, often using interviews, observations and questionnaires.

案例研究是对单一个体、群体或事件的深入调查。在 WJEC 考试中，你必须能够识别案例研究是一种非实验方法，描述其特征并评价其应用。案例研究不同于实验，它不操纵自变量，而是在一段时间内收集丰富的质性资料，通常采用访谈、观察和问卷等方法。

In the Year 12 specification, the case study method is embedded within Unit 1: Psychology: Past to Present. You are expected to discuss famous case studies such as the brain‑scanning work of Raine et al. (1997) or Bowlby’s 44 juvenile thieves, and also to critique the methodology. Being fluent in the language of case studies gives you a strong foundation for any ‘apply’ or ‘evaluate’ question.

在12年级大纲中，案例研究方法嵌入在单元1《心理学：回顾与展望》里。你既要讨论著名的案例研究，如 Raine 等人的脑扫描研究（1997）或鲍尔比的44名少年偷窃者，又要对方法论进行批判。熟练运用案例研究的术语，会为任何“应用”或“评价”类题目打下坚实基础。

2. Key Components of a Case Study | 案例研究的关键组成部分

When analysing or designing a case study, you need to identify the aim, participant, data collection techniques, findings and conclusions. These components mirror the scientific process, even without experimental control. Knowing these elements helps you structure a methodical response to a WJEC exam question that presents an unfamiliar scenario.

在分析或设计一项案例研究时，你需要识别出目的、参与者、资料收集技术、发现和结论。这些组成部分反映了科学过程，即使没有实验控制。了解这些要素有助于你针对 WJEC 考试中出现的不熟悉情境，构建出条理清晰的分析回答。

Component	What to look for
Aim	What the researcher wants to investigate, often phrased as ‘to explore…’ or ‘to understand…’
Participant	The individual or small group, usually with unique characteristics (e.g. a brain‑damaged patient, a feral child)
Method	Interviews, naturalistic observations, psychometric tests, brain scans etc.
Findings	The detailed description of behaviour, thoughts or biological markers
Conclusion	Linking back to theory, often tentative due to small sample

By dissecting any case vignette using this table, you immediately demonstrate the skill of ‘breaking down’ research – a skill examiners reward in the higher mark bands. Remember to use the exact terms from the specification: ‘qualitative data’, ‘longitudinal’, ‘subjective interpretation’ and so on.

利用这张表格来拆解任何案例片段，你就能立刻展现出“分解”研究的技能——阅卷老师在高分档会欣赏这种能力。记得使用大纲中的精确术语，例如“质性资料”、“纵向研究”、“主观解读”等。

3. Ethical Considerations in Case Analysis | 案例分析中的伦理考量

Ethical sensitivity is a non‑negotiable part of WJEC psychology. Even in a pre‑written case study, you are expected to spot potential ethical flaws and suggest improvements. The BPS guidelines – informed consent, right to withdraw, confidentiality, protection from harm and debriefing – should be at your fingertips.

伦理敏感性是 WJEC 心理学不可忽视的环节。即使是现成的案例研究，你也需要找出潜在的伦理缺陷并提出改进建议。BPS 指导原则——知情同意、退出权、保密、免受伤害和事后说明——你应该烂熟于心。

For example, a case study involving a brain‑scanned violent offender (Raine et al.) raises issues of anonymity and lasting psychological harm from being labelled ‘abnormal’. A child case study, like that of ‘Genie’ or Bowlby’s thieves, brings up safeguarding and the capacity to consent. Always ask yourself: could the participant have refused? Was their data anonymised? Did the researcher do enough to minimise stress?

比如，一项涉及脑扫描暴力犯的案例研究（Raine 等人）会引发匿名性问题，以及被贴上“异常”标签所带来的持续心理伤害。儿童案例研究，如“Genie”或鲍尔比的少年偷窃者，则会牵涉安全保护与同意能力问题。你要时刻自问：参与者能否拒绝？他们的资料是否匿名？研究者是否尽力减少了应激？

In your exam answer, weave ethical discussion into both the description and evaluation sections. A candidate who merely lists ethical guidelines loses the chance to show higher‑order thinking. Instead, explain how the specific procedure could breach a guideline and propose a practical alternative (e.g., using pseudonyms, offering counselling follow‑up).

在考试作答时，把伦理讨论融入描述和评价部分。只罗列伦理原则的考生会错失展示高阶思维的机会。相反，要说明具体程序如何可能违反某项原则，并提出可行的替代方案（如使用化名、提供辅导跟进）。

4. Applying Research Methods to Case Data | 将研究方法应用于案例数据

WJEC examiners love to ask: “Outline how the researcher could gather data for this case study.” This requires you to translate generic research method knowledge into a concrete plan. Even though a case study is holistic, you can propose triangulation – combining interviews, observations and standardised tests to strengthen validity.

WJEC 考官喜欢问：“请概述研究者可以如何为这项案例研究收集资料。”这要求你将通用的研究方法知识转化为具体方案。尽管案例研究是整体性的，你可以提出三角互证——结合访谈、观察和标准化测验来增强效度。

If the scenario involves a child with disrupted attachment, you could describe a structured observation using the Strange Situation categories devised by Ainsworth. If the case relates to memory distortion, a semi‑structured interview probing the participant’s recollection of a real‑life event would mirror the technique of Loftus and Palmer’s follow‑up studies. Always link your proposed method back to a named classic study to showcase your psychological literacy.

如果情境涉及一名依恋受损的儿童，你可以描述如何借助 Ainsworth 设计的陌生情境分类进行结构式观察。若案例与记忆扭曲有关，则可通过半结构化访谈探查参与者对真实事件的回忆，这正呼应了 Loftus 与 Palmer 后续研究中的技巧。务必把你提议的方法与一项知名经典研究关联起来，以展示你的心理学素养。

Also, consider controls that could be added without turning the study into an experiment. For instance, using the same interviewer for all sessions, keeping the room quiet and taking verbatim notes. Mentioning these details signals to the examiner that you grasp the nuances of methodology.

同时，考虑在不把研究变成实验的情况下可以加入哪些控制措施。例如，所有访谈采用同一名访问者、保持房间安静、逐字记录。提到这些细节可以向考官表明你领会了方法论的细微之处。

5. Biological Psychology Case: The Criminal Brain | 生物心理学案例：犯罪大脑

Imagine a scenario: ‘Daniel, a 29‑year‑old convicted offender of impulsive violent crimes, underwent a PET scan. The scan showed reduced glucose metabolism in his prefrontal cortex and heightened activity in the amygdala compared to a matched control group. Researchers also conducted a lengthy clinical interview and collected school reports.’ How would you analyse this from a WJEC biological psychology perspective?

设想这样一个情境：“Daniel，一名29岁冲动型暴力罪犯，接受了一次PET扫描。扫描显示，与匹配对照组相比，他的前额叶皮层葡萄糖代谢降低，杏仁核活动增强。研究者还进行了一次长时间的临床访谈并收集了学校报告。”你如何从WJEC生物心理学视角进行分析？

First, recognise this as a case study implicitly referencing Raine et al. (1997). The aim would be to explore biological correlates of impulsive violence. The method is a combination of brain imaging and qualitative interviews. You could link the prefrontal under‑activity to reduced impulse control and the amygdala over‑activity to heightened emotional reactivity. This offers a biological explanation for violent behaviour, but be careful not to fall into determinism – you must also mention the interaction with environmental factors (e.g., the school reports hinting at a troubled upbringing).

首先，要认识到这是一个暗指 Raine 等人（1997）的案例研究。研究目的可能是探寻冲动暴力的生物关联。方法结合了脑成像与质性访谈。你可以将前额叶活动不足与冲动控制力减弱联系起来，将杏仁核过度活跃与情绪反应增强联系起来。这为暴力行为提供了一种生物学解释，但要小心不要陷入决定论——你还必须提及与环境因素（如学校报告暗示的艰难成长经历）的交互作用。

When evaluating, point out that a single‑case design prevents generalisation, the PET scan provides objective data which increases scientific credibility, yet the interview data are subjective. Ethical issues include labelling and the risk that the findings could be misused to stigmatise individuals. Always finish with a balanced conclusion: biological predispositions may increase risk but do not absolve personal responsibility.

进行评价时，指出单一个案设计阻碍了概括推广，PET扫描提供客观数据提高了科学可信度，但访谈数据是主观的。伦理问题包括贴标签和结果可能被滥用来污名化个体的风险。最后一定要给出平衡的结论：生物倾向可能会增加风险，但并不能免除个人责任。

6. Social Psychology Case: Conformity and Obedience | 社会心理学案例：从众与服从

Consider this short vignette: ‘Care worker Marie was instructed by a senior doctor over the phone to administer a double dose of a new sedative to a restless patient. The instruction violated the clinic’s protocol. Marie hesitated but eventually complied, fearing that questioning the doctor would result in a formal reprimand.’ How can you use social psychology to explain Marie’s behaviour?

考虑这个简短片段：“护理员 Marie 通过电话接到一位资深医生的指示，要求她给一位烦躁的患者注射双倍剂量的新型镇静剂。这一指示违反了诊所的操作规程。Marie犹豫了一下，但最终还是服从了，她害怕质疑医生会招致正式处分。”你如何用社会心理学解释 Marie 的行为？

Immediately, you should be reminded of Milgram’s (1963) research on obedience to authority and, even closer, Hofling et al.’s (1966) hospital study where 21 out of 22 nurses obeyed an unknown doctor’s phone order to administer an excessive drug dose. Identify the factors: legitimate authority (the doctor, perceived as an expert), the authority figure’s proximity (phone call creates physical distance but the hierarchical gap remains), and the absence of a disobedient role model.

你应该立刻联想到 Milgram（1963）关于服从权威的研究，以及更接近的 Hofling 等人（1966）的医院研究——在22名护士中，有21人服从了陌生医生通过电话下达的超量用药指令。要识别出相关因素：合法权威（医生被视为专家），权威人物的接近性（电话造成了物理距离，但等级差距依然存在），以及缺少反抗的榜样。

In your answer, structure the analysis around situational variables: agentic state (Marie shifts responsibility to the doctor), buffers (the phone shields her from the patient’s potential reaction) and the gradual commitment that might occur over time. Then evaluate using the weakness of androcentric sampling in Milgram and the ethical breach of deception. Propose how you might ethically replicate the study by using a role‑play simulation with full debriefing. This demonstrates the critical application WJEC examiners seek.

在答案中，围绕情境变量来组织分析：代理状态（Marie将责任转移给医生），缓冲因素（电话使她远离患者的潜在反应），以及可能随时间发生的渐进承诺。然后，引用Milgram研究中的男性中心取样弱点以及欺骗行为的伦理缺陷进行评价。提出你可以如何通过一次全程事后说明的角色扮演模拟来在伦理允许的范围内重复该研究。这就展示了 WJEC 考官所寻求的批判性应用能力。

7. Cognitive Psychology Case: Memory Failure | 认知心理学案例：记忆失败

Case: ‘After witnessing a road traffic accident, Meg told the police that the car “smashed” into the cyclist. A week later, when asked to describe the event again, she reported seeing shattered glass on the road, although photographs from the scene showed no broken glass.’ This is pure Loftus and Palmer (1974) territory.

案例：“在目睹一起道路交通事故后，Meg 告诉警方汽车‘猛撞’（smashed）了骑自行车的人。一周后，当她再次被要求描述事件时，她报告说看到路上有碎玻璃，尽管现场照片显示并无碎玻璃。”这完全是 Loftus 与 Palmer（1974）的领域。

Explain that the leading question containing the verb ‘smashed’ activated a schema of a serious collision, which in turn created a false memory of shattered glass. This illustrates the reconstructive nature of memory: we piece together fragments of what actually happened with post‑event information. You can bring in Bartlett’s concept of schema and the misinformation effect studied by Loftus. It is a perfect demonstration of how cognitive psychology can explain everyday memory errors.

解释：含有动词“猛撞”的引导性问题激活了关于严重碰撞的图式，进而制造出关于碎玻璃的错误记忆。这说明了记忆的重构性质：我们会将实际发生的事情片段与事后信息拼凑在一起。你可以引入 Bartlett 的图式概念，以及 Loftus 所研究的错误信息效应。这极好地展示了认知心理学如何解释日常记忆错误。

For evaluation, discuss the high ecological validity of such a real‑life scenario, but also the lack of control over individual differences (Meg’s prior experiences with accidents, her emotional state). Note that laboratory experiments like Loftus and Palmer’s allowed precise control but may have suffered from demand characteristics. A case study approach, as presented here, offers richer context but limited reliability – precisely the sort of balance required for the top mark band.

进行评价时，要讨论此类现实生活情境的高生态效度，但同时也要指出对个体差异缺乏控制（Meg 以往的意外经历、情绪状态）。注意，像 Loftus 和 Palmer 那样的实验室实验可以实现精确控制，但可能存在需求特征。如此处展示的案例研究方法则提供了更丰富的背景，但信度有限——这正是在高分档中所需的权衡。

8. Developmental Psychology Case: Attachment Patterns | 发展心理学案例：依恋模式

Read the extract: ‘Three‑year‑old Leo was observed at nursery. When his mother left, he became intensely distressed and could not be comforted by staff. On reunion, he rushed to his mother but then pushed her away, arching his back. At home, his mother reported that Leo often clung to her but also showed anger when she returned after short separations.’ What attachment type does this suggest?

阅读这段摘录：“在幼儿园观察了三岁的Leo。母亲离开时，Leo变得极度痛苦，工作人员无法安抚。重聚时，他冲向母亲但随即又将她推开，身体后仰。在家中，母亲报告Leo常常粘着她，但在经历短暂分离后她又回来时也会表现出愤怒。”这提示了哪种依恋类型？

Using Ainsworth’s Strange Situation classification, this behaviour matches insecure‑resistant (Type C) attachment: high separation anxiety, difficulty in being soothed and ambivalent reunions. The case study method here allows us to gather rich detail – the mother’s diary notes, staff observations – that could not be captured by a questionnaire alone. It also brings Bowlby’s maternal deprivation hypothesis into view: if Leo’s early care was inconsistent, his internal working model may have developed negative expectations of caregivers.

利用 Ainsworth 的陌生情境分类，这一行为符合不安全—矛盾型（C 型）依恋：分离焦虑高，难以被安抚，重聚时表现出矛盾行为。这里的案例研究方法让我们能够收集丰富的细节——母亲的日记记录、教职员工的观察——这些都是单纯问卷无法捕捉的。它同时也把 Bowlby 的母爱剥夺假说带入视野：如果 Leo 的早期照料不连续，他的内部工作模型可能已经发展出对照料者的负面预期。

When evaluating, acknowledge that one case cannot establish cause and effect; temperament could be a confounding variable (Kagan’s work). However, the longitudinal potential of a case study could track Leo’s development into adolescence, testing the continuity hypothesis. This is how you move from description to critical evaluation – always thinking about what the methodology can and cannot achieve.

进行评价时，要承认单个案例无法建立因果关系；气质可能是一个混淆变量（Kagan 的研究）。然而，案例研究的纵向潜力可以追踪 Leo 进入青春期的发展，从而检验连续性假说。这就是从描述走向批判性评价的方式——始终思考方法能做到什么、不能做到什么。

9. Evaluating Strengths and Limitations | 评估优势与局限

Any WJEC case study question that asks you to ‘evaluate’ requires a structured, point‑by‑point argument. Strengths: case studies produce rich, in‑depth data that can challenge established theories; they can study rare phenomena impossible to reproduce experimentally; they often lead to practical applications (e.g., rehabilitation programmes for brain‑injured patients).

任何要求你“评价”案例研究的 WJEC 题目都需要结构化的逐点论证。优势：案例研究能产生丰富深入的资料，可以挑战既有理论；可以研究无法用实验复制的不常见现象；往往能带来实际应用（如脑损伤患者的康复方案）。

Limitations: generalisability is weak because of the tiny sample; researcher bias can colour interpretations; retrospetive data (memories, diaries) may be inaccurate; and, crucially, cause‑and‑effect conclusions cannot be drawn because variables are not isolated. To reach the highest marks, you must not only list these but also apply them to the specific case in the question. For example, “In Raine et al.’s case, the small sample of NGRI murderers prevents us from concluding that all violent individuals have the same brain pattern.”

局限：样本量小导致可推广性弱；研究者偏见可能影响诠释；回溯性资料（记忆、日记）可能不准确；最关键的是，因为变量未被隔离，无法得出因果结论。要获得最高分，你不仅要罗列这些，还要将它们应用于题目中的具体案例。例如，“在 Raine 等人的案例中，NGRI 谋杀犯的小样本使我们无法得出所有暴力个体都具有相同大脑模式的结论。”

A powerful technique is to counter one limitation with an improvement. “Although the case study lacks reliability, using a standardised interview schedule and inter‑rater reliability checks on thematic analysis can increase the trustworthiness of the findings.” This shows evaluative sophistication.

一个强有力的技巧是用改进措施来回应一个局限。“虽然案例研究缺乏信度，但使用标准化访谈提纲并对主题分析进行评分者间信度检验，可以增加研究结果的可信度。”这展示出了评价的精细度。

10. Exam Technique: Structuring Your Answer | 考试技巧：构建你的答案

When faced with a 12‑mark or 20‑mark case study question, allocate your time wisely. A proven structure for an ‘apply and evaluate’ question is: (1) Brief description – summarise the case aim and method in two sentences. (2) Apply psychological theory – map the case onto relevant classic studies with explicit links. (3) Analyse methodology – evaluate strengths and weaknesses of the case study approach shown. (4) Ethical reflection – pick at least two ethical points and suggest practical solutions. (5) Conclusion – a balanced summary, often weighing the contribution of the case study against its limitations.

面对 12 分或 20 分的案例分析题时，要合理分配时间。一种经过验证的“应用与评价”类题目结构是：（1）简要描述——用两句话概括案例的目的与方法。（2）应用心理学理论——将案例与相关经典研究联系起来，并明确对应。（3）方法分析——评价所示案例研究方法的优势与劣势。（4）伦理反思——挑选至少两个伦理要点并提出可行的解决方案。（5）结论——平衡的总结，往往衡量该案例研究的贡献与其局限。

For lower‑tariff questions (e.g. 6 marks), focus heavily on the application step. Use the ‘PEC’ formula: Point, Evidence from the case, Connect to theory. “Meg’s false memory of shattered glass is an example of the misinformation effect (Point). The verb ‘smashed’ in the police question (Evidence) encouraged her to reconstruct her memory with a schema of a severe accident (Connect to Loftus and Palmer).”

对于分值较低的题目（如 6 分），重点关注应用步骤。使用“PEC”公式：观点、来自案例的证据、联系理论。“Meg 对碎玻璃的错误记忆是错误信息效应的一个例子（观点）。警方提问中的动词‘猛撞’（证据）促使她用严重事故图式重构记忆（联系 Loftus 与 Palmer）。”
