1. Why Case Studies Matter in IGCSE Psychology | 为什么案例研究在IGCSE心理学中重要

IGCSE Psychology papers include scenario-based questions because the examiner wants to see how well you can transfer knowledge to unfamiliar examples. A case study is not just a story: it is a source of evidence that invites you to identify methods, variables, and explanations.

IGCSE心理学试卷包含基于情境的题目，因为考官想考查你将知识迁移到陌生例子中的能力。案例研究不只是一个故事：它是证据来源，要求你识别方法、变量和解释。

Strong responses treat the case as a mini investigation. You should ask what design is used, what the findings suggest, and whether the conclusion is justified. These habits earn marks across Paper 1 and Paper 2.

高分答案会把案例当作一项小型调查。你应当思考使用了什么设计、研究结果说明了什么，以及结论是否合理。这些习惯在卷一和卷二中都能帮助你得分。

In the Cambridge assessment objectives, case studies test both application and evaluation. Application means using the right theory to explain the scenario; evaluation means weighing up strengths and weaknesses of the evidence.

在剑桥评估目标中，案例研究同时考查应用和评价能力。应用指使用正确理论解释情境；评价指权衡证据的优缺点。

If you practise case study drills regularly, you will learn to write answers that are selective, psychological, and judgement-based rather than long and descriptive.

如果你定期练习案例研究，你会学会写出有选择性、有心理学依据、有判断力的答案，而不是冗长且描述性的答案。

2. The Core Approaches in the Cambridge Syllabus | 剑桥大纲的核心取向

Before practising, refresh the approaches that Cambridge IGCSE Psychology expects you to use: biological, cognitive, social, learning, and developmental. Each approach offers different explanations for behaviour and different ways of collecting evidence.

在练习之前，先回顾剑桥IGCSE心理学要求掌握的核心取向：生物、认知、社会、学习和发展取向。每种取向对行为提供不同的解释，并使用不同的证据收集方式。

In a case study, the approach mentioned in the scenario should guide your answer. If a question describes brain activity or hormones, use the biological approach; if it describes memory or attention, use the cognitive approach.

在案例研究中，情境中提到的取向应当引导你的答案。如果题目描述脑活动或激素，使用生物取向；如果描述记忆或注意力，使用认知取向。

Social influence scenarios often involve conformity, obedience, or majority pressure. Learning scenarios focus on reinforcement, punishment, imitation, or conditioning. Identifying the correct approach early prevents irrelevant answers.

社会影响类情境通常涉及从众、服从或多数人压力。学习类情境侧重强化、惩罚、模仿或条件作用。尽早识别正确取向可以避免写出无关答案。

Do not mix approaches carelessly. An examiner can reward integrated thinking, but only when the link is explicit and relevant to the question.

不要随意混用取向。考官可以奖励整合性思考，但前提是这种联系明确且与问题相关。

3. Anatomy of an IGCSE Psychology Case Study Question | IGCSE心理学案例分析题解剖

Most case study questions follow a pattern: a short scenario, then a set of sub-questions that test knowledge, application, and evaluation. Read the stem twice and underline command words such as ‘identify’, ‘explain’, ‘suggest’, and ‘evaluate’.

大多数案例分析题遵循固定结构：一段简短情境，然后是考查知识、应用和评价的小题。阅读题干两遍，并在 ‘identify’、’explain’、’suggest’、’evaluate’ 等指令词下划线。

Use the number of marks as a guide. A two-mark ‘identify’ question needs a brief, accurate answer; a six-mark ‘evaluate’ question needs points for and against a method, theory, or application.

根据分值作答。两分的 ‘identify’ 题需要简短准确的答案；六分的 ‘evaluate’ 题需要从正反两方面评价方法、理论或应用。

A good habit is to write a one-line plan before each answer. This prevents you from drifting into description when the examiner asked for evaluation.

一个好习惯是在每题动笔前写一行提纲。这可以防止你在考官要求评价时却写成了描述。

Command word	What it asks	中文含义
Identify	Name or select the correct term	识别或选出正确术语
Explain	Give reasons or describe how and why	解释原因或说明过程和理由
Suggest	Apply psychology to the scenario	将心理学应用于情境
Evaluate	Give strengths and weaknesses, then a judgement	给出优缺点，并作出判断

4. Worked Example: Memory | 实战例题：记忆

Scenario: Maya is revising for her IGCSE exams. She revises in a silent room and listens to instrumental music. In the mock exam, she recalls more information when the test room is silent. Her teacher says this supports the idea that memory is better when the learning and recall contexts match.

情境：Maya正在为IGCSE考试复习。她在安静房间里复习，同时听器乐。在模拟考试中，当考场安静时她回忆出更多信息。老师认为这支持了记忆在学习与回忆情境一致时更好的观点。

Question: Identify the type of memory cue described in the scenario. Explain one strength and one weakness of using this classroom example as evidence.

问题：指出情境中描述的记忆线索类型。解释将该课堂例子用作证据的一个优点和一个缺点。

Model answer points: The cue is context-dependent memory. A strength is that the observation has high ecological validity because it occurred in a real learning environment. A weakness is that the example is not a controlled experiment, so extraneous variables such as stress or sleep may have affected recall.

示范答案要点：该线索是情境依赖记忆。优点是观察具有较高的生态效度，因为它发生在真实学习环境中。缺点是该例子并非控制实验，因此压力或睡眠等额外变量可能影响了回忆。

When you write this in the exam, label your point, give evidence from the scenario, and then link back to the question. This point-evidence-link structure keeps your answer focused.

在考试中作答时，先标明你的观点，再引用情境中的证据，最后回扣题目。这种 ‘观点-证据-回扣’ 结构能让答案保持集中。

For top marks, explain why ecological validity matters: findings from real classrooms may generalise to other revision situations better than findings from artificial memory tests.

要拿高分，需要解释为什么生态效度很重要：来自真实课堂的研究结果可能比人为记忆测试的结果更能推广到其他复习情境。

5. Worked Example: Social Influence | 实战例题：社会影响

Scenario: A football crowd begins to shout insults at a referee after one supporter starts shouting. Some individuals later say they joined in because ‘everyone else was doing it’. A few said they were afraid of being called disloyal if they stayed quiet.

情境：一名球迷开始叫骂后，足球观众开始集体辱骂裁判。一些人事后说他们加入是因为 ‘大家都这么做’。还有少数人说他们害怕如果保持沉默会被认为不忠诚。

Question: Explain this behaviour using two social influence terms. Evaluate the use of self-report data collected after the event.

问题：使用两个社会影响术语解释这一行为。评价事后收集的自我报告数据。

Model answer points: The change can be explained by normative social influence, because individuals conformed to gain approval and avoid rejection. It may also show deindividuation in a crowd, where anonymity reduces personal responsibility.

示范答案要点：这种变化可以用规范社会影响解释，因为个体为获得认可和避免被排斥而服从。它也可能表现出人群中的去个体化，即匿名感降低个人责任感。

Self-report data is easy to collect and gives access to private motives, but it is vulnerable to social desirability bias and memory distortion. Evaluations should therefore weigh the insight against the risk of inaccurate recall.

自我报告数据易于收集，并能揭示私人动机，但容易受到社会称许性偏差和记忆扭曲的影响。因此评价时应权衡其洞见价值和回忆不准确的风险。

If the question asks you to suggest a better method, you could propose a covert observation to see whether the same individuals actually started the shouting, though this raises ethical concerns about informed consent.

如果题目要求你提出更好的方法，你可以建议使用隐蔽观察，看是否正是这些个体首先开始叫骂，但这会引发知情同意方面的伦理问题。

6. Worked Example: Learning and Behaviour | 实战例题：学习与行为

Scenario: A teacher gives a gold star to any student who answers a question correctly. Over a month, students raise their hands more often. However, when the teacher stops giving stars, hand-raising gradually decreases.

情境：一位教师给每位正确回答问题的学生颁发金星贴纸。一个月后，学生更频繁举手。但当教师停止发放贴纸后，举手行为逐渐减少。

Question: Identify the type of reinforcement and the extinction process shown. Suggest one practical change to make the new behaviour more resistant to extinction.

问题：指出所展示的强化类型和消退过程。提出一项实际改变，使新行为更不容易消退。

Model answer points: The teacher uses positive reinforcement by adding a pleasant stimulus after the target behaviour. Extinction occurs when the reinforcer is removed and the learned response weakens.

示范答案要点：教师通过目标行为后给予愉快刺激，使用了正强化。当强化物被移除后，习得反应减弱，这就是消退。

A practical change is to switch from continuous reinforcement to partial reinforcement, because behaviour learned on an unpredictable schedule is usually slower to extinguish.
