📚 Year 9 OCR Psychology: Case Study Practical Exercises | Year 9 OCR 心理学：案例分析实战演练
In Year 9 OCR Psychology, case studies are a powerful tool to explore real-life examples of psychological phenomena. This article provides practical exercises to help you develop the skill of analysing case studies, a key requirement for your course. By working through these scenarios, you will learn to identify psychological concepts, evaluate evidence, and consider ethical issues.
在 Year 9 OCR 心理学中，案例研究是探索心理学现象真实例子的有力工具。本文提供实战演练，助你培养案例分析的核心技能，这也是你课程的关键要求。通过这些情景练习，你将学会识别心理学概念、评价证据并思考伦理问题。
1. Introduction to Case Studies in Psychology | 心理学案例研究简介
A case study is an in-depth investigation of a single individual, group or event. In psychology, researchers use case studies to gather rich, detailed data that experiments alone cannot provide. The famous case of Phineas Gage, who survived an iron rod through his frontal lobe, showed how brain injury can change personality, offering insights no lab could replicate.
案例研究是对单一个体、群体或事件的深入调查。在心理学中，研究者用案例研究收集丰富、详细的资料，这是单独实验无法提供的。著名的菲尼亚斯·盖奇案例——他额叶被铁棒穿透而幸存——显示了脑损伤如何改变人格，提供了实验室无法复制的洞见。
Case studies are especially useful for studying rare conditions or unique life experiences. However, they have limitations: findings may not generalise to other people, and researchers' own interpretations can introduce bias. In your OCR course, you need to understand both the strengths and weaknesses of this method.
案例研究对于研究罕见状况或独特生活经历特别有用。但它们有局限性：结果可能无法推广到其他人，研究者自身的解释也可能引入偏差。在你的 OCR 课程中，你需要理解这种方法的优点和缺点。
2. The OCR Year 9 Case Study Approach | OCR Year 9 案例研究方法
When you face a case study in an OCR assessment, follow a clear structure. Start by identifying the key psychological issue. Then link it to a theory or concept you have studied, such as memory, social influence, or attachment. Next, evaluate the evidence: what does the case tell you, and what might be missing or biased?
在 OCR 评估中遇到案例研究时，遵循清晰的结构。首先识别关键心理学问题，然后将它与学过的理论或概念联系起来，例如记忆、社会影响或依恋。接着评价证据：案例告诉了你什么，可能缺少什么或存在什么偏见？
You should also consider methodological aspects. Is the data qualitative or quantitative? How was it gathered? Could there be ethical concerns? Practising this approach regularly will build your confidence for written tasks and discussions.
你还应该考虑方法层面。数据是定性还是定量的？如何收集的？是否有伦理方面的担忧？定期练习这种方法将为你的书面任务和课堂讨论建立信心。
3. Case Study 1: The Memory of a Witness | 案例一：证人的记忆
Alex, a 14-year-old student, witnessed a heated argument in the school canteen. Two days later, when a teacher asked what happened, Alex said he clearly remembered the older student throwing a water bottle and shouting insults. However, CCTV footage showed the bottle was actually on a table and the older student only raised his voice without throwing anything. Alex was surprised by the discrepancy.
14 岁的学生亚历克斯目睹了学校食堂里的一场激烈争吵。两天后，当老师询问情况时，亚历克斯说他清楚记得高年级学生扔了一个水瓶并辱骂。然而，监控录像显示水瓶其实在桌子上，高年级学生只是提高了嗓门，并没有扔东西。亚历克斯对记忆的出入感到惊讶。
Later, his friends told him that 'that older guy always throws stuff when he's angry', which might have influenced Alex's recall. This real-world scenario mirrors classic psychological research on eyewitness testimony.
后来，他的朋友告诉他 '那个高年级的家伙生气时总扔东西'，这可能影响了亚历克斯的回忆。这个真实情景与经典的目击证词心理学研究相似。
4. Analysing Case Study 1: Key Concepts | 分析案例一：关键概念
This case illustrates the reconstructive nature of memory. According to Bartlett (1932), memory is not a perfect recording; we rebuild memories using schemas – mental frameworks shaped by our expectations and past experiences. Alex's schema for 'angry older student' may have filled gaps with the idea of throwing objects.
这个案例说明了记忆的重构性质。根据巴特利特 (1932)，记忆并非完美录制；我们利用图式——由期望和过去经验塑造的心理框架——重建记忆。亚历克斯关于 '愤怒的高年级学生' 的图式可能用扔东西的想法填补了空白。
The misinformation effect (Loftus & Palmer, 1974) is also relevant here. Post-event information, like his friends' comments, can alter memory. In fact, leading questions or discussions after an event can implant false details. For OCR, you might explain that Alex's memory was contaminated by the verbal suggestion that the older student throws things.
误导信息效应 (洛夫特斯与帕尔默，1974) 在此也很重要。事后信息，例如朋友的评论，可以改变记忆。事实上，诱导性问题或事后讨论可能植入虚假细节。针对 OCR，你可以解释亚历克斯的记忆被那位高年级学生扔东西的言语暗示污染了。
Furthermore, the case raises the issue of ecological validity. While it happened naturally, CCTV allowed verification – something rare in real-life eyewitness situations. This highlights the gap between lab findings and everyday memory.
此外，这个案例提出了生态效度的问题。虽然它自然发生，但监控录像提供了验证——这在真实目击情境中很少见。这突显了实验室发现与日常记忆之间的差距。
5. Case Study 2: Conformity in the Classroom | 案例二：课堂中的从众
In a Year 9 art lesson, five students were asked to estimate the length of a curved line on the board. Four of them were confederates who deliberately gave a wrong answer: 30 cm. The real participant, Sam, initially thought the line was about 20 cm but, after hearing the others, said '30 cm' to fit in. When interviewed alone later, Sam admitted the line looked shorter but didn’t want to look foolish.
在一堂九年级美术课上，五名学生被要求估测黑板上一条曲线的长度。其中四人是事先安排好的假被试，故意给出错误答案：30 厘米。真正的参与者萨姆起初觉得线条大约 20 厘米，但听到其他人的回答后，为了合群也说 '30 厘米'。后来单独访谈时，萨姆承认线条看起来更短，但不想让自己显得愚蠢。
This situation is based on Asch's (1951) conformity experiments, adapted for a school setting. It shows how social pressure can override private judgement.
这个情景基于阿希 (1951) 的从众实验，并改编为学校场景。它显示了社会压力如何压倒个人判断。
6. Analysing Case Study 2: Social Influence | 分析案例二：社会影响
Sam's behaviour is a clear example of normative social influence (NSI). NSI occurs when a person conforms to be accepted or avoid rejection. Sam changed the answer publicly but privately disagreed – a pattern known as compliance. Asch found that even with an unambiguous task, participants conformed about 37% of the time when the group gave a wrong answer.
萨姆的行为是规范性社会影响 (NSI) 的明显例子。当一个人为了被接纳或避免排斥而顺从时，就发生了规范性社会影响。萨姆公开改变了答案，但私下并不同意——这种模式被称为依从。阿希发现，即使任务明确，当群体给出错误答案时，参与者仍有约 37% 的试次从众。
Alternatively, informational social influence (ISI) could play a role if Sam doubted his own perception. However, Sam's later admission that the line looked shorter suggests NSI was dominant. In OCR terms, you should distinguish between compliance (public) and internalisation (private acceptance), which isn't shown here.
另外，如果萨姆怀疑自己的感知，信息性社会影响 (ISI) 可能也起了作用。但萨姆后来承认线条看起来更短，表明规范性社会影响占主导。用 OCR 术语说，你应该区分依从 (公开) 和内化 (私下接受)，而这里没有表现出内化。
Ethical considerations: the use of confederates and deception in this classroom activity mirrors the original Asch study. Students gave consent but were not told the true purpose, which raises questions about protection from psychological harm – even if the task was low-stakes, Sam felt discomfort.
伦理考量：这个课堂活动使用假被试和欺骗，类似于阿希原始实验。学生们同意了，但没有被告知真实目的，这引发了关于保护参与者免受心理伤害的问题——即使任务风险很低，萨姆也感到了不适。
7. Case Study 3: Attachment and Separation | 案例三：依恋与分离
Three-year-old Mia has attended the same nursery for six months. When her mother drops her off, Mia clings to her leg, cries for a few minutes, and then gradually settles to play. When her mother returns, Mia runs to her with outstretched arms and quickly calms down. The nursery staff report that Mia is wary of strangers but can be soothed by familiar caregivers.
三岁的米娅已在同一所幼儿园上了六个月。母亲送她时，米娅会抱住母亲的腿，哭几分钟，然后慢慢平静下来玩耍。母亲回来时，米娅伸开双臂跑向她，并很快平静。幼儿园老师报告说米娅警惕陌生人，但能被熟悉的保育员安抚。
This typical pattern of behaviour can be understood through attachment theory. Mia's reactions are consistent with a secure attachment style, as classified by Ainsworth's 'Strange Situation' procedure.
这种典型行为模式可以通过依恋理论来理解。米娅的反应符合安斯沃斯 '陌生情境' 程序所分类的安全型依恋风格。
8. Analysing Case Study 3: Bowlby's Theory | 分析案例三：鲍尔比理论
Bowlby (1969) proposed that infants form a strong emotional bond with a primary caregiver, usually the mother, which serves as a secure base for exploration. Mia uses her mother as a safe haven: she is distressed at separation but recovers because she trusts her mother will return. This is a key feature of a secure attachment.
鲍尔比 (1969) 提出，婴儿与主要照护者 (通常是母亲) 形成强烈的情感纽带，这成为探索的安全基地。米娅以母亲为安全港：分离时她痛苦，但因相信母亲会回来而恢复。这是安全型依恋的关键特征。
Using Ainsworth's (1978) categories, Mia shows secure behaviour – she seeks proximity, shows distress on separation, and is easily comforted on reunion. She does not display avoidant (ignoring the caregiver) or resistant (ambivalent and angry) patterns. For your OCR analysis, you can link her wariness of strangers to stranger anxiety, which typically emerges around 8 months.
根据安斯沃斯 (1978) 的分类，米娅表现出安全型行为——她寻求亲近，分离时痛苦，重逢时容易安抚。她没有表现出回避型 (忽视照护者) 或矛盾型 (摇摆不定且愤怒) 模式。在你的 OCR 分析中，你可以将她对陌生人的警惕与陌生人焦虑联系起来，这通常在 8 个月左右出现。
However, a single case study cannot prove that secure attachment is caused by sensitive parenting. Bowlby's maternal deprivation hypothesis would require longitudinal data. Nonetheless, Mia's case is a good illustration of concepts like proximity-seeking and secure-base behaviour in a naturalistic setting.
然而，单一案例研究不能证明安全型依恋是由敏感养育造成的。鲍尔比的母爱剥夺假说需要纵向数据。尽管如此，米娅的案例很好地说明了自然情境中寻求亲近和安全基地行为等概念。
9. Common Pitfalls in Case Study Analysis | 案例分析常见误区
One common mistake is overgeneralisation: assuming that what is true for one person applies to everyone. A case study provides depth but not breadth, so avoid phrases like 'this proves that all teenagers…' Instead, use 'this suggests' or 'this supports the idea that…'.
一个常见误区是过度推广：假设对一个人成立的事实也适用于所有人。案例研究提供深度而非广度，因此避免使用 '这证明所有青少年…' 这样的说法，而应使用 '这表明' 或 '这支持了…的概念'。
Another pitfall is ignoring researcher bias. When a case study relies on self-report or observations, the researcher's own beliefs can shape data collection and interpretation. In your answer, always consider who collected the data and how their perspective might have influenced it.
另一个误区是忽视研究者偏见。当案例研究依赖自我报告或观察时，研究者自身的信念会影响数据收集和解释。在你的回答中，始终要考虑谁收集了数据，以及他们的视角可能如何影响了数据。
Finally, forgetting to mention ethics can cost marks. Even if a case seems harmless, discuss issues like consent, confidentiality, and the right to withdraw. In Mia's case, did the parents give informed consent for the observation? Was her identity protected?
最后，忘记提及伦理问题可能失分。即使案例看似无害，也要讨论知情同意、保密和退出权等问题。在米娅的案例中，家长对观察给予了知情同意吗？她的身份得到了保护吗？
10. Applying Ethical Considerations | 应用伦理考量
All psychological research, including case studies, must follow ethical guidelines. The British Psychological Society (BPS) sets out principles such as respect, competence, responsibility, and integrity. For Year 9 OCR, you should be able to identify how these apply to each scenario.
所有心理学研究，包括案例研究，都必须遵循伦理准则。英国心理学会 (BPS) 制定了尊重、胜任、责任和诚信等原则。对于 Year 9 OCR，你应该能够识别这些原则如何应用于每个情景。
In the memory witness case, Alex's experience was shared for educational purposes. Even if anonymised, using a real event raises questions: did Alex agree to his mistake being analysed? Could it cause embarrassment? The ethical recommendation would be to obtain retrospective consent and debrief fully.
在记忆证人案例中，亚历克斯的经历被用于教育目的。即使匿名了，使用真实事件也引发问题：亚历克斯同意自己的错误被分析了吗？会不会造成尴尬？伦理建议是获得追溯同意，并进行充分的事后解说。
For the conformity activity, the deception about confederates is ethically sensitive. A proper debrief after the session is essential to explain the purpose and reassure participants. Consent forms should mention that the exact aim will be revealed afterwards, following BPS rules on deception.
在从众活动中，关于假被试的欺骗在伦理上很敏感。活动结束后进行适当的事后解说是必要的，以解释目的并安抚参与者。同意书应提及确切目的将在事后公布，遵循 BPS 关于欺骗的规定。
In attachment observations, maintaining confidentiality and anonymity is paramount. Recordings or detailed notes should be stored securely. If the case study is published, no identifying details should be included.
在依恋观察中，维护保密和匿名至关重要。录像或详细笔记应安全存放。如果案例研究被发表，不应包含任何可识别身份的细节。
11. Practice Exercise: Design Your Own Case Study | 实战练习：设计你自己的案例
Now it's your turn. Think of a psychological concept you have studied – for example, operant conditioning, stress, or phobias. Design a brief case study about a fictional person that illustrates this concept. Write a paragraph describing the person, the situation, and the behaviour.
现在轮到你了。想一个你学过的心理学概念——例如，操作条件作用、压力或恐惧症。设计一个简短的关于虚构人物的案例研究，来说明这个概念。写一段描述人物、情景和行为的文字。
Then, write an analysis using the OCR approach: identify the concept, link it to a theory, evaluate the case's strengths and weaknesses, and comment on ethical issues. Swap your case study with a classmate and see if they can spot the same concepts you intended.
然后，用 OCR 方法写一段分析：识别概念，将其与一个理论联系起来，评价案例的优点和缺点，并评论伦理问题。和同学交换案例研究，看他们能否发现你想要展现的相同概念。
For example, you could describe a teenager who checks their phone constantly and feels anxious without it. You might link this to addiction or negative reinforcement. This active practice is one of the most effective ways to prepare for your assessments.
例如，你可以描述一个青少年不断查看手机，没有手机就感到焦虑。你可以将此与成瘾或负强化联系起来。这种主动练习是备考评估的最有效方式之一。
12. Conclusion and Exam Tips | 总结与考试技巧
Case study analysis is a skill that develops with practice. Remember to always connect the scenario to specific psychological theories and terminology – OCR examiners look for accurate use of key terms like 'reconstructive memory', 'normative social influence', or 'secure attachment'.
案例分析是一项通过练习逐渐发展的技能。记住始终将情景与具体的心理学理论和术语联系起来——OCR 考官看重准确使用诸如 '重构记忆'、'规范性社会影响' 或 '安全型依恋' 等关键术语。
Use the 'PEE' structure in your written answers: Point (identify the issue), Evidence (from the case or research), and Explain (link to theory). Evaluate by noting what the case cannot tell you, and always mention generalisability and ethics. Keep practising with different scenarios, and you'll be well prepared for any case study question.
在书面答案中使用 'PEE' 结构：观点 (识别问题)、证据 (来自案例或研究) 和解释 (联系理论)。通过指出案例无法告诉你的事情来评价，并始终提及推广性和伦理。不断练习不同的情景，你将为任何案例研究问题做好准备。
