1. What Is a Case Study in Psychology? | 什么是心理学中的案例研究？
A case study is an in-depth investigation of a single individual, group, or event. In psychology, it is used to gather rich, detailed data over a period of time through methods such as interviews, observations, and psychological tests. Unlike experiments, case studies do not manipulate variables; instead, they describe and analyse behaviour in a real-world context.
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，通过访谈、观察和心理测试等方法，在一段时间内收集丰富而详细的数据。与实验不同，案例研究不操纵变量；而是在真实世界的情境中描述和分析行为。
For Year 9 students, practising case studies means learning to connect a scenario with psychological concepts. For example, you might be given a short description of a child who struggles to separate from a parent, and you would be expected to discuss attachment theory and relevant research. This skill is assessed in CIE Psychology to check your application and evaluation abilities.
对于九年级学生，练习案例分析意味着要学会将情景与心理学概念联系起来。例如，你可能会拿到一个关于孩子难以与家长分离的简短描述，并需要讨论依恋理论和相关研究。CIE 心理学通过这种题型考查你的应用和评价能力。
2. Core Psychological Perspectives to Apply | 需要运用的核心心理学视角
Before diving into scenarios, it helps to have a clear mental map of the key perspectives and theories you can draw on. The main areas covered in Year 9 CIE Psychology include cognitive psychology, developmental psychology, and social psychology. Below are some of the most relevant concepts:
在深入情景之前，心中要有一张清晰的地图，明确可以运用哪些关键视角和理论。CIE 九年级心理学涵盖的主要领域包括认知心理学、发展心理学和社会心理学。以下是最相关的一些概念：
Cognitive psychology: Multi-store model of memory (Atkinson & Shiffrin, 1968), the distinction between short-term and long-term memory, and forgetting as a result of displacement or decay.
认知心理学： 记忆的多存储模型（Atkinson & Shiffrin，1968），短时记忆与长时记忆的区分，以及由于干扰或消退导致的遗忘。
Developmental psychology: Attachment theory (Bowlby), the Strange Situation and attachment types (Ainsworth, 1978), and the concept of the internal working model.
发展心理学： 依恋理论（Bowlby），陌生情境实验和依恋类型（Ainsworth，1978），以及内部工作模型的概念。
Social psychology: Conformity (Asch, 1951), the role of normative and informational social influence, and factors affecting obedience or compliance.
社会心理学： 从众（Asch，1951），规范性社会影响与信息性社会影响的作用，以及影响服从或顺从的因素。
3. Case Study 1: Memory – Why Do We Forget? | 案例一：记忆 – 我们为何遗忘？
Read the following scenario carefully:
仔细阅读以下情景：
'Sarah, a Year 9 student, always forgets to bring her homework diary to school. She can remember what her grandmother told her during a holiday three years ago, but she cannot recall the three items her friend just asked her to buy from the canteen. Her teacher notices that Sarah often remembers the first and last things said in a lesson but struggles with the middle part.'
“Sarah 是一名九年级学生，她总是忘记带家庭作业记录本到学校。她能记住三年前假期里祖母告诉她的事情，但记不住朋友刚刚让她从食堂买的三样东西。她的老师注意到，Sarah 常常能记住一堂课最先和最后说的内容，但对中间部分感到困难。”
Your task is to explain Sarah's memory experiences using psychological theories. This is a classic case where the multi-store model and serial position effect can be directly applied.
你的任务是运用心理学理论解释 Sarah 的记忆体验。这是一个典型的情景，可以直接应用多存储模型和系列位置效应。
4. Step-by-Step Analysis for Case Study 1 | 案例一的逐步分析
First, identify the psychological concepts present in the scenario. Sarah' e model, STM has a limited capacity of about 7 ± 2 items and a short duration of around 18– e items likely exceeded her attention span and were displaced by new incoming information.
首先，识别情景中出现的心理学概念。Sarah 无法回忆朋友要求的三样东西，表明短时记忆（STM）出现了问题。根据多存储模型，STM 的容量有限，约为 7 ± 2 个项目，在没有复述的情况下持续时间大约为 18–30 秒。这三样东西很可能超出了她的注意力范围，并被新进入的信息所取代。
Second, Sarah's ability to remember her grandmother's story from years ago can be linked to long-term memory (LTM). Information that is rehearsed or emotionally significant is encoded into LTM, which has potentially unlimited capacity and duration. The emotional connection with her grandmother likely strengthened the memory trace.
其次，Sarah 能够记住多年前祖母的故事，这与长时记忆（LTM）有关。经过复述或具有情感意义的信息会被编码进 LTM，后者的容量和持续时间几乎是无限的。与祖母的情感联系很可能增强了记忆痕迹。
Third, the teacher's observation that Sarah recalls the first and last parts of a lesson but forgets the middle is a clear example of the serial position effect. Research by Murdock (1962) demonstrated that items at the beginning (primacy effect) enter LTM through rehearsal, and items at the end (recency effect) are still held in STM. Items in the middle are poorly recalled because they receive less rehearsal and are displaced.
第三，老师观察到 Sarah 能记住一堂课的开始和结尾却忘记中间部分，这是系列位置效应的一个明显例子。Murdock（1962）的研究表明，开头部分（首因效应）通过复述进入 LTM，结尾部分（近因效应）仍保留在 STM 中，而中间部分因复述较少且被干扰，所以回忆不佳。
5. Case Study 2: Attachment – Understanding a Child's Behaviour | 案例二：依恋 – 理解儿童行为
Now consider this developmental psychology scenario:
现在考虑这个发展心理学情景：
'Tom is three years old and has just started nursery. When his mother drops him off, Tom clings to her and cries loudly. After she leaves, he refuses to play with other children and stares at the door. When his mother returns, Tom runs to her but then pushes her away and continues to cry. The nursery staff say his behaviour is quite consistent.'
“Tom 三岁了，刚开始上幼儿园。当妈妈送他时，Tom 紧抓着妈妈不放，大声哭泣。妈妈离开后，他拒绝和其他小朋友玩，一直盯着门。当妈妈回来时，Tom 跑向她，但随后又把她推开，继续哭闹。幼儿园老师表示他的行为相当一致。”
This description provides clues about Tom's attachment type. To analyse it effectively, you need to recall Ainsworth's Strange Situation classification and the theory of attachment.
这段描述提供了关于 Tom 依恋类型的线索。要有效分析，你需要回忆 Ainsworth 的陌生情境分类和依恋理论。
6. Applying Attachment Theories and Research | 运用依恋理论与研究
Tom's behaviour closely matches that of an insecure-resistant (Type C) attachment. In Ainsworth's Strange Situation, infants with this pattern typically show intense distress upon separation from the caregiver. When the caregiver returns, they display ambivalent behaviour: they seek contact but also resist it, showing anger or rejection. This is exactly what we see when Tom runs to his mother and then pushes her away.
Tom 的行为与不安全-抗拒型（C 类）依恋高度吻合。在 Ainsworth 的陌生情境实验中，具有这种模式的婴儿通常在照顾者离开时表现出强烈的痛苦。当照顾者返回时，他们表现出矛盾行为：既寻求接触，又抗拒接触，往往带有愤怒或拒绝。这正是我们看到 Tom 跑向母亲、然后又推开她的情况。
From Bowlby's perspective, attachment serves an evolutionary function: the child seeks proximity to the primary caregiver for survival and comfort. Tom's extreme distress signals that he does not have a secure base. His internal working model of relationships seems to involve anxiety and uncertainty, possibly because the caregiver has been inconsistent in responding to his needs.
从 Bowlby 的角度看，依恋具有进化功能：孩子寻求与主要照顾者亲近，以获得生存和安慰。Tom 的极度痛苦表明他没有形成安全基地。他关于关系的内部工作模型似乎包含焦虑和不确定感，这可能是因为照顾者在回应他的需求时表现得不一致。
To strengthen your analysis, you should mention a relevant study. Ainsworth's (1978) Strange Situation study observed 12- to 18-month-old infants and found that approximately 70% displayed secure attachment, while around 12% showed insecure-resistant attachment. Tom's case illustrates that minority pattern and highlights the role of caregiver sensitivity in shaping attachment.
为了加强分析，你应该提及相关研究。Ainsworth（1978）的陌生情境研究观察了 12 至 18 个月的婴儿，发现大约 70% 表现出安全型依恋，约 12% 呈现不安全-抗拒型依恋。Tom 的案例说明了这种少数模式，并突显了照顾者敏感性在塑造依恋中的作用。
7. Case Study 3: Social Influence – Conformity in the Classroom | 案例三：社会影响 – 课堂中的从众
Consider this scenario set in a school context:
考虑这个以学校为背景的情景：
'During a psychology lesson, the class is shown two cards: Card A has one line, and Card B has three lines of different lengths. The teacher asks each student to say aloud which line on Card B matches the length of the line on Card A. Most students, who have been told to give wrong answers, confidently say 'B-3'. Sam, the last student, knows B-3 is clearly too long, but he feels pressure to agree with the group. In the end, he gives the same incorrect answer on 6 out of 10 trials.'
“在一节心理学课上，全班看到两张卡片：卡片 A 上有一条线段，卡片 B 上有三条长度不同的线段。老师要求每个学生大声说出卡片 B 上哪条线段与卡片 A 上的线段长度相同。大多数学生（已被事先告知要给出错误答案）自信地说‘B-3’。Sam 是最后一个发言的学生，他知道 B-3 明显太长，但感到来自群体的压力。最终，他在 10 次测试中有 6 次给出了相同的错误答案。”
This is a replica of Solomon Asch's classic conformity study (1951). Even though the task is unambiguous, social pressure can lead individuals to conform.
这是 Solomon Asch 经典从众研究（1951）的再现。尽管任务非常明确，社会压力仍能导致个体从众。
8. Using Research Evidence Effectively | 有效使用研究证据
When you write about Sam's behaviour, start by naming the relevant theory: normative social influence. This is the desire to fit in and be accepted by the group, which is especially strong in classroom settings among teenagers. Sam conformed publicly without changing his private belief because he wanted to avoid standing out or being ridiculed.
当你描述 Sam 的行为时，先从提及相关理论开始：规范性社会影响。这是一种想要融入群体并被接纳的渴望，在青少年课堂环境中尤其强烈。Sam 公开从众，却没有改变自己的内在判断，因为他想避免显得突出或被嘲笑。
To back up your point, cite Asch's (1951) original experiment. In that study, 75% of participants conformed at least once, and the overall conformity rate across all trials was around 37%. By comparing Sam's 6 out of 10 conforming responses (60%), you can note that his conformity level is notably higher than Asch's average. This might be due to factors such as being the only dissenter, the group's age, or the high status of peers.
为了支撑论点，可以引用 Asch（1951）的原始实验。在该研究中，75% 的参与者至少从众过一次，所有试验中的平均从众率约为 37%。通过比较 Sam 在 10 次中 6 次的从众反应（60%），你可以指出他的从众程度明显高于 Asch 的平均水平。这可能是因为他是唯一的异议者、群体的年龄，或同伴的高地位等因素造成的。
Always remember to link the study back to the case. Do not just describe the experiment; explain what it tells us about the person in the scenario.
永远记住要将研究回链到案例本身。不要仅仅描述实验，而要解释它对情景中人物的行为说明了什么。
9. Structuring Your Written Response | 构建书面回答结构
A strong case study answer follows a clear structure. One helpful approach is the PEEL paragraph: Point, Evidence, Explanation, Link. Begin by stating your point directly – for example, 'Sam's behaviour can be explained by normative social influence.' Then introduce evidence from a named study, such as 'In Asch's (1951) line-judgement task, participants often conformed to an incorrect majority.' Next, explain how the evidence applies to the case, and finally link back to the question or scenario.
一个有力的案例分析答案遵循清晰的结构。一种有用的方法是 PEEL 段落：Point（观点）、Evidence（证据）、Explanation（解释）、Link（链接）。首先直接陈述你的观点——例如，“Sam 的行为可以用规范性社会影响来解释”。然后引用一个具体研究的证据，例如“在 Asch（1951）的线段判断任务中，参与者经常屈从于错误的多数意见”。接下来解释证据如何应用于该案例，最后链接回问题或情景。
| Stage | What to do |
|---|---|
| Point | State the psychological concept clearly. |
| Evidence | Describe a specific study that supports the concept. |
| Explanation | Explain how the evidence directly applies to the case. |
| Link | Connect your analysis back to the individual or the question's focus. |
Using this framework ensures you are not simply retelling the story, but are providing a psychological analysis.
使用这一框架可以确保你不仅仅是在复述故事，而是在提供心理学分析。
10. Common Pitfalls and How to Avoid Them | 常见误区及避免方法
One frequent mistake is merely describing the case study without applying any psychology. For instance, saying 'Tom cried when his mother left' is just a description, not an analysis. Always ask yourself: which theory or model explains this behaviour? Another pitfall is mentioning a study without explaining its relevance. Naming 'Ainsworth' is not enough; you must connect the study's findings to the specific behaviours shown.
一个常见的错误是仅仅描述案例研究，而没有应用任何心理学知识。例如，说“Tom 在母亲离开时哭了”只是描述，不是分析。要一直问自己：哪个理论或模型能解释这一行为？另一个误区是提及一个研究却未解释其相关性。仅仅说出“Ainsworth”是不够的；你必须将该研究的发现与案例中显示的具体行为联系起来。
Students also sometimes confuse different concepts, such as mixing up normative and informational social influence. Remember: normative influence is about fitting in and being liked; informational influence is about being right and looking to others for guidance in ambiguous situations. Check the scenario carefully to decide which one fits.
学生有时也会混淆不同的概念，比如将规范性社会影响和信息性社会影响混为一谈。请记住：规范性影响是为了融入和被喜欢；信息性影响是在不确定的情况下为了追求正确而向他人寻求指导。仔细检查情景，决定哪种解释更为合适。
Lastly, avoid using vague terms like 'memory is bad' or 'attachment is weak'. Use psychological vocabulary precisely: 'STM capacity is limited', 'displacement in LTS', or 'insecure-resistant attachment'. Precision gains marks.
最后，避免使用模糊的词语，如“记忆力差”或“依恋很弱”。要精确使用心理学词汇：“STM 容量有限”、“LTM 中的干扰”，或“不安全-抗拒型依恋”。用词精确才能得分。
11. Practice Scenarios for Self-Assessment | 自我评估练习情景
Try analysing these brief scenarios on your own. After reading each one, write a short PEEL paragraph and then check your ideas against the hints provided.
尝试自己分析以下简短情景。在阅读每一个后，写一个简短的 PEEL 段落，然后对照给出的提示检查你的想法。
Scenario A: 'Mia always revises by reading her notes silently. She scored low on a test last week, but her friend Louis, who reads notes aloud and draws mind maps, did very well. Their psychology teacher says Mia might not be encoding information deeply enough.' Which memory concept applies here?
情景 A: “Mia 总是通过默读笔记来复习。上周她测试成绩很低，但她的朋友 Louis 朗读笔记并画思维导图，成绩很好。他们的心理学老师说 Mia 可能没有对信息进行足够深的编码。”这里适用哪个记忆概念？
Hint: Consider levels of processing theory (Craik & Lockhart, 1972). Mia's shallow processing (silent reading) leads to weak long-term memory, while Louis's deeper processing (elaborative rehearsal) strengthens retention.
提示：考虑加工层次理论（Craik & Lockhart，1972）。Mia 的浅层加工（默读）导致长时记忆薄弱，而 Louis 的深层加工（精细复述）加强了记忆保持。
Scenario B: 'A Year 9 tutor group starts leaving rubbish on the floor because one popular student says it is 'cool'. Soon, most students join in, even though they know it is against school rules.' Which type of social influence is at work?
情景 B: “一个九年级辅导小组开始把垃圾扔在地上，因为一个受欢迎的学生说这样‘很酷’。很快，大多数学生都跟着做，尽管他们知道这违反了校规。”这里是哪种社会影响在起作用？
Hint: This is normative social influence coupled with a desire for social approval. The popular student acts as a role model, and conformity increases because the group values acceptance over rule-following.
提示：这是规范性社会影响，加上渴望获得社会认同。那个受欢迎的学生充当了榜样，从众行为增加，因为群体将接纳看得比遵守规则更重要。
12. Summary and Final Tips | 总结与最后提示
To excel in Year 9 CIE Psychology case studies, always follow a four-step mental checklist: (1) Identify the psychological concepts in the scenario; (2) Select the most relevant theory or model; (3) Support your point with a named research study and explain how it applies; (4) Conclude by linking back to the individual's behaviour. Practice using PEEL paragraphs until the structure becomes automatic.
要在 CIE 九年级心理学案例分析中取得优异成绩，始终遵循四步心理检查清单：（1）识别情景中的心理学概念；（2）选择最相关的理论或模型；（3）用一个明确命名的研究来支持你的观点，并解释其如何适用；（4）通过链接回个体行为来得出结论。反复练习使用 PEEL 段落，直到这一结构变得自动。
Remember that psychology is a science of evidence. Every claim you make should be tied to a theory or a piece of research. Even if the scenario seems like common sense, your answer needs the specialist language and reference to studies that distinguish a psychological analysis from an everyday opinion. Review the key studies mentioned here – Atkinson & Shiffrin, Ainsworth, Asch – and be ready to discuss them concisely.
要记住，心理学是一门讲究证据的科学。你提出的每个主张都应联系到一个理论或一项研究。即使情景看起来像是常识，你的答案也需要使用专业语言并引用研究，这样才能将心理学分析与日常观点区分开来。复习本文提到的关键研究——Atkinson & Shiffrin、Ainsworth、Asch——并准备好简洁地讨论它们。
Finally, simulate exam conditions: time yourself and write a full analysis for each of the three main case studies in this guide. By practising under pressure, you will refine your ability to think quickly and write accurately. Case studies are not something to fear; they are an opportunity to show how well you can apply what you have learned.
最后，模拟考试情境：给自己计时，为本指南中的三个主要案例各写一份完整的分析。通过在压力下练习，你将提高快速思考和准确写作的能力。案例分析并不可怕；它们是一个展示你能够多好地应用所学知识的机会。
