📚 GCSE AQA Psychology: Case Study Practical Exercises | GCSE AQA 心理学：案例分析实战演练
This article is designed to sharpen your ability to tackle the case study questions that appear in both Paper 1 and Paper 2 of the AQA GCSE Psychology examination. You will learn how to identify key psychological concepts, apply research methods knowledge, and critically evaluate classic and contemporary studies through a series of structured practical exercises.
本文旨在帮助你在AQA GCSE心理学考试中精准应对案例分析题。通过一系列结构化实战演练，你将学会如何识别核心心理学概念、运用研究方法知识，并对经典与当代研究进行批判性评价，从而在Paper 1和Paper 2中游刃有余。
1. What Is a Case Study in GCSE Psychology? | 什么是GCSE心理学中的案例分析？
A case study is an in-depth investigation of a single individual, group, or event. In AQA GCSE Psychology, case studies are often used to illustrate key theories and research methods. They require you to apply your knowledge to a novel scenario, demonstrating understanding rather than mere recall.
案例分析是对单一个体、群体或事件的深入调查。在AQA GCSE心理学中，案例分析常被用来阐释关键理论与研究方法。这类题目要求你将所学知识应用到全新情境中，展现的是理解力而不仅仅是记忆。
For example, you might be given a description of a memory experiment and asked to identify the independent variable, or a vignette about a child’s cognitive development where you must link behaviour to Piaget’s stages. Case studies test skills across AO2 (application) and AO3 (evaluation).
例如，你可能会拿到一段记忆实验的描述并被要求找出自变量，或者一段关于儿童认知发展的文字材料，你需要将行为与皮亚杰的认知阶段联系起来。案例分析同时考查AO2（应用）与AO3（评价）技能。
2. Why Case Studies Matter in the AQA Exams | 为何案例分析在AQA考试中如此重要
The AQA specification places a strong emphasis on applying psychological knowledge to real-world contexts. Case study questions typically account for 6 to 9 marks, often combining short-answer and extended writing elements. Mastering them can significantly boost your grade.
AQA考纲非常强调将心理学知识应用于真实情景。案例分析题通常占6到9分，往往结合简答题与扩展写作。掌握这部分能显著提升你的成绩等级。
These questions appear in sections like Memory, Perception, Development, Social Influence, and Brain and Neuropsychology. They also integrate research methods, requiring you to comment on experimental design, sampling, or ethical issues within the story presented.
这类题目会出现在记忆、感知、发展、社会影响以及大脑与神经心理学等章节中。它们还融合研究方法，要求你在故事背景下评述实验设计、抽样或伦理问题。
3. Core Skills Required for Analysing Case Studies | 分析案例所需的核心技能
To succeed, you need to cultivate three interconnected skills: identification, application, and evaluation. Begin by spotting the psychological content—theories, concepts, or research features embedded in the scenario. Then link them explicitly to what you have learned. Finally, weigh strengths and limitations.
要取得成功，你需要培养三项相互关联的技能：识别、应用与评价。首先要找出情境中蕴含的心理学内容——理论、概念或研究特征。然后将其与你学过的知识明确联系起来。最后，权衡优势与局限。
Identification: Pinpoint the research design (e.g., independent groups, repeated measures), the IV and DV, sampling method, or the specific behaviour being studied.
识别：指出研究设计（例如独立组设计、重复测量设计）、自变量和因变量、抽样方法或所研究的特定行为。
Application: Explain how a theory like Atkinson and Shiffrin’s multi-store model accounts for the behaviour described, or why Asch’s conformity line study is relevant.
应用：解释阿特金森和谢夫林的多重储存模型这样的理论如何解释所描述的行为，或阿希的从众线条实验为何相关。
Evaluation: Discuss generalisability, ecological validity, reliability, ethical considerations, and practical applications using evidence from the case.
评价：利用案例中的证据讨论普遍性、生态效度、信度、伦理考量以及实际应用价值。
Practice moving beyond story retelling. Always connect the dots back to psychological terminology and published research.
练习时不要停留在复述故事。要始终用心理学术语和已发表的研究把各个要点串联起来。
4. Case Study Drill 1: The Memory Experiment | 案例实战1：记忆实验
Read the scenario: “Dr. Kim wanted to test whether background music affects recall. She divided 30 participants into two groups: Group A learned a list of 20 words in silence, while Group B learned the same list with instrumental music playing. Both groups were tested immediately. Group A recalled an average of 15 words, and Group B recalled 12 words.”
阅读以下情景：“金博士想测试背景音乐是否影响回忆。她将30名参与者分成两组：A组在安静环境中学习20个单词，B组在有器乐演奏的环境中学习同样的单词。两组均立即接受测试。A组平均回忆15个单词，B组平均回忆12个单词。”
Identify the experimental design. “Independent groups design is used because different participants were assigned to each condition.”
识别实验设计。“使用了独立组设计，因为不同参与者被分配到不同的实验条件中。”
State the IV and DV. “IV is the presence or absence of music; DV is the number of words correctly recalled.”
说出自变量和因变量。“自变量是有无音乐；因变量是正确回忆的单词数量。”
Suggest one extraneous variable and how to control it. “Individual differences in memory span could act as an extraneous variable. Random allocation of participants to conditions would help control this.”
提出一个额外变量及控制方法。“个体记忆广度的差异可能成为额外变量。将参与者随机分配至各条件有助于控制这一变量。”
Link to the multi-store model. “Better recall in silence supports the idea that attention is needed to transfer information from sensory register to short-term memory; music may have divided attention.”
联系多重储存模型。“安静条件下回忆更好支持了以下观点：信息从感觉登记转入短时记忆需要注意；音乐可能分散了注意力。”
5. Case Study Drill 2: Conformity in the Classroom | 案例实战2：教室里的从众
“A teacher noticed that when she asked the class to estimate the number of marbles in a jar, students who answered after hearing their peers’ guesses tended to give similar answers, even when the initial guess was clearly too high. She repeated this with different classes and found the pattern consistent.”
“一位老师注意到，当她让学生估计罐子里弹珠的数量时，那些在听到同伴的猜测后才回答的学生往往会给出相似的答案，即使最初的猜测明显过高。她在不同班级重复试验，发现该模式始终存在。”
Which type of conformity does this illustrate? “This is normative social influence, where individuals conform to be liked or accepted by the group, as identified by Deutsch and Gerard (1955).”
这体现了哪种从众类型？“这是规范性社会影响，个体为了被群体喜欢或接纳而从众，由Deutsch与Gerard（1955）提出。”
How does Asch’s research explain this outcome? “Asch’s line study demonstrated that about 75% of participants conformed at least once due to group pressure, even when the correct answer was obvious. The classroom scenario mirrors this distortion of judgement.”
阿希的研究如何解释这一结果？“阿希的线条实验表明，约75%的参与者至少因群体压力从众过一次，即使正确答案显而易见。教室情景正反映了这种判断扭曲。”
Evaluate the generalisability of Asch’s study when applied to this class. “Asch used male American undergraduates, which limits cultural and gender generalisability. However, the teacher’s informal replication across different classes strengthens the claim that this behaviour is widespread.”
评价将阿希研究应用于这个班级时的普遍性。“阿希使用了美国男性大学生，这限制了文化和性别方面的普遍性。然而，这位老师在不同班级的非正式重复实验加强了这一行为普遍存在的主张。”
6. Case Study Drill 3: A Child’s Conservation Task | 案例实战3：儿童的守恒任务
“Five-year-old Mia is shown two identical glasses with the same amount of juice. The juice from one glass is poured into a tall, thin beaker. Mia insists the tall beaker now has ‘more juice’ than the remaining glass. Her seven-year-old brother Yusuf correctly states the amounts are equal.”
“五岁的米娅看到两个相同的杯子里装有等量的果汁。其中一个杯子里的果汁被倒入一个高而细的烧杯后，米娅坚持认为高烧杯里的果汁‘更多’。她七岁的哥哥尤瑟夫正确地指出两个容器里的果汁量相等。”
Identify the stage of cognitive development for each child. “Mia is in Piaget’s pre-operational stage (2–7 years), characterised by centration and lack of conservation. Yusuf is in the concrete operational stage (7–11 years), where children can conserve quantity.”
识别每个孩子所处的认知发展阶段。“米娅处于皮亚杰的前运算阶段（2-7岁），表现为中心化和缺乏守恒能力。尤瑟夫处于具体运算阶段（7-11岁），这个阶段的孩子能理解数量守恒。”
Why might Mia have failed the conservation task? “She focuses on the perceptually salient feature—height of the liquid—while ignoring compensation (width). She also shows irreversibility, unable to mentally reverse the pouring action.”
米娅为何未能通过守恒任务？“她只关注感知上最显著的特征——液体的高度，而忽略了补偿因素（宽度）。她也表现出不可逆性，无法在心理上逆转倒果汁的动作。”
Criticise Piaget’s methodology based on this case. “Piaget’s conservation tasks have been criticised for lacking ecological validity—children rarely encounter such artificial scenarios. Additionally, Hughes’ ‘policeman doll’ study suggests that when tasks are made more child-friendly, even children in the pre-operational stage can show logical thinking, challenging Piaget’s age-bound stages.”
基于该案例批评皮亚杰的方法论。“皮亚杰的守恒任务因缺乏生态效度受到批评——孩子很少遇到如此人为创设的情景。此外，休斯的‘警察玩偶’实验表明，当任务对孩子更友好时，前运算阶段的孩子也能展现逻辑思维，这对皮亚杰的年龄阶段划分提出了挑战。”
7. Case Study Drill 4: The Story of Phineas Gage | 案例实战4：菲尼亚斯·盖奇的故事
“In 1848, Phineas Gage, a railroad foreman, survived a severe brain injury when a tamping iron pierced his frontal lobe. After the accident, his personality changed dramatically—from responsible and sociable to impulsive and irritable—while his memory and language remained intact.”
“1848年，铁路工头菲尼亚斯·盖奇遭遇严重脑损伤，一根铁夯刺穿了他的额叶，但他活了下来。事故后，他的性格发生了巨大变化——从负责、善交际变得冲动、易怒，而他的记忆和语言能力却完好无损。”
What does this case tell us about localisation of function? “Gage’s case provided early evidence that the frontal lobes are involved in regulating personality, impulse control, and social behaviour, while other functions are located elsewhere.”
这个案例告诉我们关于脑功能定位的什么信息？“盖奇的案例提供了早期证据，表明额叶参与调节人格、冲动控制和社会行为，而其它功能位于大脑的其它部位。”
Explain one strength of using a case study for brain research. “A case study allows incredibly detailed, longitudinal insight into a unique condition that could never be ethically or practically reproduced in an experiment.”
解释使用案例研究进行大脑研究的一个优势。“案例研究能对独一无二的状况进行极为详细的纵向观察，无论是在伦理上还是实际操作中，这种状况都无法通过实验再现。”
Discuss a major limitation of this single case. “Gage’s case is idiographic—based on one individual—so findings may not generalise to others with similar injuries. Furthermore, accounts of his personality change relied on anecdotal reports from acquaintances, which may be biased or exaggerated.”
讨论这个单一案例的一个主要局限。“盖奇的案例是特殊个案——仅基于一个个体——因此研究结果可能无法适用于其他相似损伤者。另外，对他性格变化的描述依赖于熟人的轶事报告，可能存在偏见或夸大。”
8. Ethical Considerations in Case Studies | 案例分析中的伦理考量
Ethical issues are a frequent focus in exam case studies. You may be asked to identify breaches of the British Psychological Society’s (BPS) ethical guidelines or to suggest improvements to protect participants.
伦理问题是考试案例分析中的常见关注点。你可能会被要求找出违反英国心理学会（BPS）伦理准则的地方，或提出改进措施以保护参与者。
| Ethical Principle / 伦理原则 | Example Violation in a Case Study / 案例中的违规示例 | How to Address It / 如何解决 |
| Informed Consent / 知情同意 | A researcher observed children in a playground without informing parents. / 研究者未通知家长便观察操场上的儿童。 | Obtain parental consent and, where possible, assent from the children. / 获得家长同意，并尽可能获得儿童的赞同。 |
| Deception / 欺骗 | Participants were told the study was about perception, but their memory was being tested. / 参与者被告知实验与感知有关，但实际测的是记忆力。 | Debrief participants fully at the end and offer the right to withdraw data. / 实验结束后充分进行事后解释，并允许参与者撤回数据。 |
| Protection from Harm / 免受伤害 | A procedure caused embarrassment or anxiety, as in some conformity studies. / 实验过程造成尴尬或焦虑，如某些从众研究。 | Stop the study if distress is observed and provide support; design tasks to minimise discomfort. / 观察到痛苦时立即停止研究并提供支持；设计任务时尽量减少不适。 |
| Confidentiality / 保密性 | A participant’s name and test scores appeared in a published report. / 参与者的姓名和测试分数出现在公开报告中。 | Use codes or pseudonyms; never publish identifiable information. / 使用编码或化名；绝不公布可识别信息。 |
Always link the ethical issue directly to the story—don’t just list principles. Explain why the breach matters and what specific action the researcher should have taken.
永远要将伦理问题与故事直接关联——不要只罗列原则。解释为什么这种违规行为事关重大，以及研究者本应采取哪些具体措施。
9. Evaluating Research Methods in a Case Study Context | 在案例情境中评价研究方法
AQA examiners expect you to evaluate the methodology that underpins the scenario. Whether it is a laboratory experiment, a naturalistic observation, or a brain scan, you must be able to discuss strengths and weaknesses using precise psychological terminology.
AQA考官希望你评价情境中所使用的研究方法。无论是实验室实验、自然观察还是脑部扫描，你都必须能够用精确的心理学术语讨论其优势与不足。
Internal validity: Does the design allow firm cause-and-effect conclusions? “The use of a standardised procedure and counterbalancing strengthens internal validity by controlling order effects.”
内部效度：研究设计是否允许得出确切的因果关系结论？“使用标准化程序和平衡设计能控制顺序效应，从而增强内部效度。”
Ecological validity: How well do findings translate to real life? “The laboratory setting is artificial, so the behaviour observed (e.g., obedience to an authority figure) may not reflect how people act outside the lab—a criticism levelled at Milgram’s study.”
生态效度：研究发现多大程度上可以迁移到现实生活中？“实验室环境是人为的，所以观察到的行为（如服从权威人物）可能无法反映人们在实验室外的表现——这是对米尔格拉姆研究的一种批评。”
Reliability: Could the study be replicated? “The use of a detailed script and fixed-response questionnaires increases replicability.”
信度：研究可否被重复？“使用详细的脚本和固定回答问卷提高了可复制性。”
Sampling and generalisability: “A sample of 20 psychology students obtained through opportunity sampling may produce biased findings. Random sampling from a target population is preferable.”
抽样与普遍性：“通过便利抽样获得的20名心理学专业学生样本可能会产生有偏差的结果。从目标人群中随机抽样更为可取。”
Practice the ‘PEEL’ structure in your evaluation paragraphs: Point, Evidence from the case, Explanation of the psychological concept, Link back to the question.
在评价段落中练习“PEEL”结构：论点、案例中的证据、心理学概念的解释、回扣问题。
10. Mock Paper in Action: A Full Case Study with Model Answers | 模拟实战：完整案例分析及范答
Study the following information carefully and then attempt the questions that follow.
仔细研究以下信息，然后尝试回答后续问题。
Scenario: “A psychologist wanted to investigate the impact of praise on pupils’ motivation in mathematics. She visited a secondary school and selected a Year 7 class. Over four weeks, every Monday and Wednesday, the teacher gave public verbal praise to five pupils who had been randomly chosen from the class every time they completed a problem correctly. The other 20 pupils received no praise. The psychologist recorded the number of optional maths problems each pupil completed during break time.”
情境：“一位心理学家想研究表扬对小学生数学学习动机的影响。她来到一所中学，选取了一个七年级班级。在四周时间里，每周一和周三，只要被随机从班里选出的五名学生在解题时答对，老师就公开口头表扬他们。其余20名学生没有得到表扬。心理学家记录了每个学生在课间完成的额外数学题数量。”
Question 1 (2 marks): Identify the type of experimental design used. / 问题1（2分）：指出所用的实验设计类型。
Model answer: Independent groups design, because different participants were allocated to the praise condition and the no-praise condition, and they were not matched. / 范答：独立组设计，因为不同的参与者被分配到表扬条件和不表扬条件，且他们未进行匹配。
Question 2 (3 marks): Explain one ethical issue the psychologist should have considered. / 问题2（3分）：解释心理学家本应考虑的一个伦理问题。
Model answer: The psychologist should have considered the protection of participants from psychological harm. The pupils who received no praise may have experienced lowered self-esteem or frustration during maths lessons. To address this, the researcher could have debriefed all pupils after the study and ensured that the no-praise group later received positive feedback to restore any loss of confidence. / 范答：心理学家本应考虑保护参与者免受心理伤害。未得到表扬的学生可能在数学课上感到自尊心受挫或产生挫败感。为解决这一问题，研究者可以在研究结束后向所有学生进行事后解释，并确保无表扬组后续得到正面反馈以恢复可能受损的信心。
Question 3 (4 marks): Using your knowledge of social learning theory, discuss whether the results of this study would support Bandura’s ideas. / 问题3（4分）：运用社会学习理论的知识，讨论本研究的结果是否会支持班杜拉的观点。
Model answer: Bandura’s social learning theory suggests that behaviour can be learned through observation and vicarious reinforcement. If the five pupils who were praised completed more maths problems, the other pupils might have witnessed this praise (vicarious reinforcement) and thus be motivated to imitate that behaviour. However, the study only measured the individual output, not observational learning effects. To fully support Bandura, the psychologist would need to show that the non-praised pupils also increased their problem-solving after observing their peers being rewarded. / 范答：班杜拉的社会学习理论认为，行为可以通过观察和替代强化习得。如果被表扬的五名学生完成了更多数学题，其他学生可能目睹了这种表扬（替代强化），从而被激发去模仿该行为。然而，本研究仅测量了个人的产出，而没有测量观察学习效应。要完全支持班杜拉，心理学家需要证明未受表扬的学生在观察到同伴被奖励后，也增加了自己的解题数量。
This mock exercise demonstrates how multiple assessment objectives are woven into a single narrative. Always use psychological concepts as the backbone of your answers.
这个模拟练习展示了多个评估目标是怎样交织在一个单一叙述中的。永远将心理学概念作为你答案的主干。
11. Common Pitfalls and How to Avoid Them | 常见误区与规避策略
Many students lose marks by simply summarising the scenario without adding psychological value. Another mistake is evaluating a study without linking the criticism back to the specific details of the case. Avoid vague statements like “the study lacks ecological validity” without explaining why the setting or task is unrealistic in that particular story.
许多学生失分的原因是仅仅总结了情境而没有增添心理学价值。另一个错误是评价研究时未能将批评点与案例的具体细节关联起来。避免没有解释为何在该特定故事中环境或任务不真实，就笼统地写“该研究缺乏生态效度”。
Other pitfalls include: confusing ethical guidelines with research methods, failing to use the correct terminology (e.g., saying ‘the people were split up’ instead of ‘the participants were allocated randomly’), and not managing time effectively on longer 9-mark questions. Practice writing timed responses using the PEEL structure so you can construct a balanced evaluation swiftly.
其他误区包括：将伦理准则与研究方法混淆，未能使用正确术语（例如说‘人们被分开’而不是‘参与者被随机分配’），以及在较长的9分题上时间管理不当。练习使用PEEL结构进行限时作答，这样你就能迅速构建出平衡的评价。
12. Final Checklist Before the Exam | 考前终极核对表
Before you sit your GCSE Psychology paper, run through this quick checklist for case study success.
在参加GCSE心理学考试之前，请快速浏览这份案例分析成功核对表。
Can I spot the IV, DV, and experimental design in any research description? / 我能在任何研究描述中找出自变量、因变量和实验设计吗？
Do I know at least two strengths and two limitations for each key study (Peterson & Peterson, Asch, Piaget, Penfield, etc.)? / 对于每个关键研究（Peterson & Peterson、阿希、皮亚杰、潘菲尔德等），我是否知道至少两个优点和两个局限？
Am I able to connect a given behaviour to a relevant psychological theory without simply naming it? / 我能否将给定行为与相关的心理学理论联系起来，而不仅仅是命名？
Have I practiced linking ethical principles to concrete examples? / 我是否练习过将伦理原则与具体例子联系起来？
Do I structure evaluation answers using point, evidence, explanation, and link? / 我是否使用论点、证据、解释和回扣的结构来组织评价性答案？
If you can answer ‘yes’ to all five, you are well-prepared to turn any case study narrative into high-scoring marks.
如果你能对全部五个问题回答‘是’，你就已经做好充分准备，可以将任何案例分析叙述转化为高分的得分点。
