📚 Year 9 CCEA Psychology: Case Study Practical Exercises | Year 9 CCEA 心理学：案例分析实战演练
Psychology is not just about memorising theories; it is about understanding how those theories apply to real people. Case studies allow us to step into someone else's life and use psychological concepts to explain behaviour, thoughts, and emotions. In this article, we will practise analysing different scenarios, linking each one to a key theory you will encounter in Year 9 CCEA Psychology. By the end, you will feel more confident in breaking down a case, selecting the right theory, and discussing ethical considerations.
心理学不只是记住理论，更是理解这些理论如何适用于真实的人。案例分析让我们走进他人的生活，用心理学概念来解释行为、思维和情绪。在这篇文章里，我们将练习分析不同的情境，并将每个情境与你在 Year 9 CCEA 心理学中会接触到的关键理论联系起来。到最后，你会更有信心拆解案例、选择正确的理论并探讨伦理考量。
1. What Is a Case Study in Psychology? | 什么是心理学案例研究？
A case study is an in-depth investigation of a single person, group, or event. Researchers gather data using interviews, observations, questionnaires, and sometimes psychological tests. The aim is to build a rich, detailed picture that can help explain unique or unusual behaviour.
案例研究是对单一个人、群体或事件的深入调查。研究者通过访谈、观察、问卷，有时还包括心理测验来收集资料。其目的在于建立一幅丰富而详细的图像，以帮助解释独特或异常的行为。
Case studies are particularly useful when psychologists cannot conduct experiments for ethical or practical reasons. For example, studying a child who has experienced extreme neglect can offer insights into attachment, but it would be unethical to create such conditions in a lab.
当心理学家因为伦理或实际原因无法进行实验时，案例研究尤其有用。例如，研究一个经历过极端忽视的儿童可以提供关于依恋的深刻见解，但在实验室里创造这样的条件是不道德的。
However, case studies do have limitations. Because they focus on one individual, we cannot always generalise the findings to the wider population. The researcher’s own interpretations may also introduce bias.
然而，案例研究也有局限。由于它们聚焦于单独个体，我们并不总能将发现推广到更广泛的人群。研究者自身的解读也可能带来偏见。
2. The Step-by-Step Approach to Case Analysis | 案例分析的分步方法
To analyse a case study effectively, you can follow a simple four-step framework. This structure will help you stay organised and make sure you cover everything examiners are looking for.
为了有效地分析案例，你可以遵循一个简单的四步框架。这个结构有助于你保持条理清晰，并确保涵盖考官期望的所有内容。
Below is a table summarising the steps. Keep it in mind as we work through the cases later.
下表概括了这些步骤。在后续的案例分析中请牢记它。
| Step | English | 中文 |
|---|---|---|
| 1 | Describe the behaviour or experience. | 描述行为或经历。 |
| 2 | Link to a relevant psychological theory. | 与相关的心理学理论建立联系。 |
| 3 | Apply the theory to explain the case. | 应用该理论来解释案例。 |
| 4 | Evaluate strengths and weaknesses of the explanation. | 评估该解释的优点与不足。 |
When you practise, start by highlighting key details in the case. Then ask yourself: which Year 9 theory best fits this scenario? Always use psychological terminology to show depth of understanding.
练习时，可以从圈出案例中的关键细节入手。然后问自己：哪个 Year 9 的理论最适合这个情境？务必使用心理学术语，以展示理解的深度。
3. Case Study 1: Remembering a Day Out – The Multi-Store Model | 案例一：回忆外出的一天——多存储模型
Jamie, aged 14, describes his birthday trip to a theme park. He recalls the loud roar of the roller coaster, the taste of candyfloss, and the exact moment his friend screamed on the log flume. Interestingly, he cannot remember the colour of the ticket booth assistant's shirt, even though he looked right at her when buying tickets.
14 岁的杰米描述了他去主题公园的生日之旅。他记得过山车震耳欲聋的轰鸣、棉花糖的味道，还有朋友在激流勇进上尖叫的那一刻。有意思的是，尽管买票时他直视着售票员，却想不起她衬衫的颜色。
This case can be explained using the Multi-Store Model of Memory (Atkinson & Shiffrin). Information enters sensory memory, where it is held very briefly. If we pay attention to it, the information moves to short-term memory; otherwise it is forgotten. Jamie paid attention to the exciting sounds and tastes but did not attend to the assistant's shirt colour, so that sensory trace decayed rapidly.
这个案例可以用记忆的多存储模型（阿特金森和谢夫林）来解释。信息首先进入感觉记忆，在此短暂保持。如果我们加以注意，信息就会转移到短时记忆；否则就会遗忘。杰米注意了刺激的声音和味道，却没有注意售票员衬衫的颜色，因此那个感觉痕迹很快就消退了。
Short-term memory has a limited capacity (about 7±2 items) and duration of around 18–30 seconds without rehearsal. Jamie' ed them by talking about the day with his family, transferring them into long-term memory.
短时记忆的容量有限（约 7±2 个项目），在没有复述的情况下持续时间约为 18–30 秒。杰米生动的记忆之所以保留下来，是因为他通过与家人谈论这一天进行了复述，从而将其转入长时记忆。
When applying the model, we can say that paying attention to sensory input, engaging in rehearsal, and forming strong episodic memories all explain Jamie's experience. A limitation is that the model oversimplifies memory as a linear flow; it does not explain why some unrehearsed events still stick, like a traumatic moment.
在应用该模型时，我们可以说注意感觉输入、进行复述以及形成强烈的情景记忆都能解释杰米的经历。一个局限是，该模型将记忆过度简化为线性流程；它无法解释为什么某些未经复述的事件（如创伤性时刻）仍然挥之不去。
4. Case Study 2: Conformity in the Classroom – Asch’s Study | 案例二：教室里的从众行为——阿希实验
During a maths lesson, the teacher asks the class to estimate the length of a line on the board. Maya thinks the line is about 15 cm, but five classmates confidently answer 20 cm. Although Maya knows her answer is closer, she hesitates and then says 20 cm to match the others. Later she tells her friend she felt pressure not to stand out.
在一节数学课上，老师让全班估算黑板上一条线段的长度。玛雅觉得线段大约 15 厘米，但五位同学却信心十足地回答 20 厘米。尽管玛雅知道自己的答案更接近，她犹豫了一下，随后说出 20 厘米以与他人一致。后来她对朋友说，自己感受到了不想出头的压力。
This is a clear example of conformity, fitting Solomon Asch’s classic research. Asch found that participants often gave obviously wrong answers to a line-judgment task when they heard several confederates giving the same incorrect response. He concluded that normative social influence – the desire to fit in and be accepted – drives such behaviour.
这是一个明显的从众例子，契合所罗门·阿希的经典研究。阿希发现，当参与者听到几名研究助手都给出相同的错误答案时，他们在判断线段的任务中也常常给出明显错误的回答。他得出结论，规范型社会影响——即渴望融入和被接纳——驱动了这种行为。
Maya experienced normative social influence: she knew the correct answer but conformed to avoid disapproval. Factors that increase conformity include group size (up to about four people), unanimity of the group, and the task being public. All were present in the classroom.
玛雅经历的是规范型社会影响：她知道正确答案却选择从众，以免遭到否定。增加从众的因素包括群体规模（大约达到四人）、群体的一致性以及任务的公开性。这些因素在课堂中全部具备。
Applying Asch’s study helps explain why Maya acted as she did. However, the situation was not a lab experiment, so other variables, like Maya's relationship with her classmates, may also have played a role. Furthermore, Asch’s study was criticised for using a biased sample of American male students, limiting generalisability.
应用阿希的研究有助于解释玛雅的行为。不过，这个情境并非实验室实验，因此其他变量，比如玛雅与同学的关系，可能也起了作用。此外，阿希的研究被批评使用了美国男学生这一有偏样本，限制了可推广性。
5. Case Study 3: A Strange Situation – Attachment Types | 案例三：陌生情境——依恋类型
One-year-old Leo and his mother enter a playroom. Leo explores the toys happily, occasionally looking back at his mother. When a stranger enters, Leo is a little wary but warms up when his mother smiles. When his mother leaves the room, Leo cries and cannot be comforted by the stranger. Upon her return, he immediately crawls to her, reaches out to be picked up, and calms down within seconds.
一岁的利奥和妈妈进入一间游戏室。利奥高兴地探索着玩具，偶尔回头看看妈妈。陌生人进入时，利奥有点警惕，但在妈妈微笑后就放松了。当妈妈离开房间，利奥哭泣起来，陌生人无法安抚他。妈妈回来后，利奥立刻爬向她，伸出双手要抱抱，几秒钟内就平静下来。
Mary Ainsworth’s Strange Situation study identified three main attachment types: secure, insecure-avoidant, and insecure-resistant. Leo’s behaviour matches a secure attachment. Securely attached infants use their caregiver as a safe base from which to explore, show distress when separated, and are easily soothed upon reunion.
玛丽·安斯沃思的陌生情境研究确定了三种主要的依恋类型：安全型、不安全-回避型和不安全-反抗型。利奥的行为与安全型依恋相符。安全型依恋的婴儿把照顾者当作探索的安全基地，分离时表现出痛苦，重聚时容易得到安抚。
An insecure-avoidant child would likely ignore the mother and show little distress, while an insecure-resistant child would be clingy, extremely upset upon separation, and resist comfort on reunion. Leo showed neither pattern.
不安全-回避型儿童可能忽视妈妈且几乎不表现出痛苦，而不安全-反抗型儿童则会过度黏人，分离时极其不安，重聚时又抗拒安慰。利奥没有表现出这两种模式。
The case highlights how sensitive responsiveness from a caregiver usually leads to secure attachment. Criticism of the Strange Situation includes the fact that it is a short, artificial observation and may not reflect care in the home. Also, cultural differences in parenting mean behaviours might be interpreted differently across contexts.
该案例突显了照顾者的敏感回应通常如何促成安全型依恋。对陌生情境的批评包括：这是一个短暂、人为的观察，可能无法反映家庭中的照顾情况。此外，养育方式存在文化差异，行为在不同背景下可能会有不同解读。
6. Case Study 4: Exam Stress – The Fight-or-Flight Response | 案例四：考试压力——战或逃反应
Zara is sitting in the exam hall. Her heart pounds, her palms sweat, and her breathing becomes rapid as the papers are handed out. She feels a surge of energy but also a sense of panic. Twenty minutes later, she is able to focus, and the physical sensations subside a little.
扎拉正坐在考场里。试卷下发时，她的心脏狂跳、手心出汗、呼吸变得急促。她感到一股能量涌上来，但同时也有一丝恐慌。二十分钟后，她能够集中注意力，身体感觉稍有缓解。
This reaction is the body’s acute stress response, often called the fight-or-flight response. When the brain perceives a threat – in this case, a high-stakes exam – the hypothalamus activates the sympathetic nervous system and the adrenal medulla, releasing adrenaline and noradrenaline. These hormones increase heart rate, redirect blood to muscles, and sharpen alertness.
这种反应是身体的急性应激反应，常被称为战或逃反应。当大脑察觉到威胁时——这里指高风险考试——下丘脑会激活交感神经系统和肾上腺髓质，释放肾上腺素和去甲肾上腺素。这些激素会加快心率、将血液重新导向肌肉并提高警觉性。
The fight-or-flight response is adaptive when facing physical danger, but during exams it can be less helpful, especially if it triggers panic. Once Zara realises the exam is manageable, her parasympathetic nervous system begins to calm her body down.
战或逃反应在面对身体危险时具有适应性，但在考试中可能就不那么有用了，尤其是当它引发恐慌时。一旦扎拉意识到考试是可以应对的，她的副交感神经系统便开始让身体平静下来。
We can also link this case to Selye’s General Adaptation Syndrome: the alarm stage (initial shock), resistance stage (coping with the stressor), and eventually exhaustion if stress is prolonged. Fortunately for Zara, the exam is short enough to stay within the resistance stage.
我们还可以把这个案例与塞利的一般适应综合征联系起来：警戒期（初始冲击）、抵抗期（应对压力源）以及如果压力延长最终会进入衰竭期。对扎拉而言，幸运的是考试时间短，足以停留在抵抗期。
An evaluative point is that the fight-or-flight response research was based mainly on male animals and participants; women may show a ‘tend-and-befriend’ pattern under stress. Also, individual differences mean some students experience more intense physical arousal than others.
需要评估的一点是，战或逃反应的研究主要基于雄性动物和男性参与者；女性在压力下可能表现出“照料与结盟”模式。此外，个体差异意味着有些学生的生理唤醒比其他人更强烈。
7. Case Study 5: Phobia of Dogs – Classical Conditioning | 案例五：怕狗——经典条件作用
Six-year-old Evie used to love playing with her neighbour’s Labrador. One day, while running with a toy, the dog accidentally knocked her over and she fell hard onto the pavement, hurting her wrist. Since that incident, Evie freezes and starts trembling whenever she sees any dog, even small, friendly ones.
六岁的伊薇过去很喜欢和邻居家的拉布拉多犬玩耍。有一天，她拿着玩具跑的时候，那只狗不小心撞倒了她，她重重摔在人行道上，伤了手腕。从那以后，伊薇一看到任何狗，哪怕是小型友善的狗，都会僵住并开始发抖。
This phobia can be understood through Ivan Pavlov’s classical conditioning. Before the incident, the dog (neutral stimulus) produced no fear. The painful fall was an unconditioned stimulus (US) that naturally caused fear (unconditioned response, UR). The dog was present when the pain occurred, so it became associated with the US. After conditioning, the dog alone (now a conditioned stimulus, CS) triggers the conditioned response (CR) of fear.
这种恐惧症可以通过伊万·巴甫洛夫的经典条件作用来理解。在事件发生之前，狗（中性刺激）不会引起恐惧。痛苦的摔倒是一个无条件刺激，自然引起了恐惧（无条件反应）。疼痛发生时狗在场，因此狗与无条件刺激产生了联结。条件化之后，狗单独出现（现已成为条件刺激）便会引发恐惧的条件反应。
Generalisation has also occurred because Evie now fears all dogs, not just the Labrador. Higher-order conditioning may explain why even the sound of a dog barking or a picture of a dog can trigger anxiety.
泛化也发生了，因为伊薇现在害怕所有的狗，而不只是那只拉布拉多犬。高阶条件作用或许能解释为什么连狗叫声或狗的图片都能引发焦虑。
Classical conditioning offers a clear explanation, but it does not account for the cognitive element – Evie may also have developed irrational beliefs about dogs that maintain the fear. Treatments such as systematic desensitisation, based on counter-conditioning, could help her unlearn the phobia gradually.
经典条件作用提供了清晰的解释，但它没有说明认知因素——伊薇可能也已发展出关于狗的非理性信念，从而维持了恐惧。基于反条件作用的系统脱敏等治疗方法可以帮助她逐步消除恐惧。
8. Ethics in Case Study Research | 案例研究中的伦理
Whenever psychologists work with human participants, ethical principles must be followed. Even when analysing case studies in class, it is important to think about how the data was obtained and how the person’s rights were protected.
心理学家只要与人类被试工作，就必须遵循伦理原则。即便是在课堂上分析案例，思考数据是如何获取的以及当事人的权利如何受到保护也很重要。
The four main ethical guidelines in psychological research are: informed consent, confidentiality, protection from harm, and the right to withdraw. In a case study, a researcher must ensure the participant (or their guardian) fully understands what the study involves and agrees to take part.
心理学研究中的四项主要伦理准则为：知情同意、保密、免受伤害以及退出权。在案例研究中，研究者必须确保被试（或其监护人）完全理解研究内容并同意参加。
Confidentiality means personal details should be anonymised. Names are usually changed, and identifying information is removed. In our case examples, names like Jamie and Maya are pseudonyms, protecting the real individuals’ identities.
保密意味着个人信息应当匿名化。姓名通常会被更改，可识别信息则被删除。在我们的案例示例中，杰米和玛雅等名字均为化名，保护了真实个体的身份。
Protection from harm requires that no psychological or physical damage occurs. If recalling a trauma is part of a case study, the psychologist must provide support and stop if distress is too great. The right to withdraw allows participants to leave at any time without penalty.
免受伤害要求不发生任何心理或身体上的损害。如果案例研究中需要回忆创伤事件，心理学家必须提供支持，并在痛苦过大时停止。退出权允许被试在任何时候退出而不受惩罚。
As students, we should be sensitive when discussing real-life inspired scenarios and avoid making judgements. Ethical thinking not only makes you a better psychology student but also a more empathetic person.
作为学生，我们在讨论受真实生活启发的情境时应当保持敏感，避免作出评判。伦理思考不仅让你成为更好的心理学学习者，也让你成为更有同理心的人。
9. Conclusion: Becoming a Confident Psychology Student | 结论：成为自信的心理学学生
Case studies offer a bridge between abstract theories and everyday life. Through the exercises in this article, you have practised describing behaviour, linking it to core Year 9 theories, applying those theories step by step, and offering evaluations. Whether it is memory, social influence, attachment, stress, or conditioning, the skill of case analysis remains the same.
案例研究在抽象理论与日常生活之间架起了一座桥梁。通过本文的练习，你已经练习了描述行为、将其与 Year 9 核心理论相联系、逐步应用那些理论并提供评价。无论是记忆、社会影响、依恋、压力还是条件作用，案例分析的技能都是一样的。
Keep a short checklist when you work on new cases: identify the key feature, name the relevant theory, use technical terms, say why the theory applies, and then mention one strength and one limitation. Regular practice will transform case studies from intimidating puzzles into rewarding challenges.
当你分析新案例时，请保留一份简短的清单：识别关键特征，说出相关理论，使用专业术语，解释该理论为何适用，然后指出一个优点和一个局限。规律的练习会将案例分析从令人生畏的谜题转变为富有成就感的挑战。
Psychology is ultimately about people. Every case study is a story, and you now have the tools to understand those stories with both scientific rigour and genuine curiosity.
心理学归根结底是关于人的。每一个案例研究都是一个故事，你现在拥有了以科学严谨和真诚好奇心理解这些故事的工具。
