📚 Year 7 Edexcel Psychology: Case Study Analysis in Practice | 案例分析实战演练：Year 7 Edexcel 心理学
In Year 7 Psychology, you will be asked to read and analyse real-life scenarios using what you have learned in lessons. This article is a hands-on workshop designed to build your confidence with case study questions. It will guide you through the key steps of analysis, show you worked examples, and help you avoid common errors. By the end, you will be ready to tackle any case-based question in your Edexcel assessment.
在七年级心理学中，你需要运用课堂所学阅读和分析真实情境。本文是一次动手实践的工作坊，旨在帮助你建立对案例研究问题的信心。它将引导你掌握分析的关键步骤，展示详尽的范例，并帮助你避免常见错误。到最后，你将准备好应对 Edexcel 评估中任何基于案例的问题。
1. What Is a Case Study in Psychology? | 什么是心理学案例研究？
A case study in psychology is a detailed examination of an individual, a group or a particular event. Unlike a laboratory experiment, it takes place in a real-world context. In your Edexcel Year 7 course, you will often be presented with a short description of a situation and then asked to explain what is happening using psychological theories.
心理学中的案例研究是对个人、群体或特定事件的详细考察。与实验室实验不同，它发生在真实世界的情境中。在你的 Edexcel 七年级课程中，你经常会遇到一段简短的情境描述，然后被要求运用心理学理论来解释发生了什么。
These tasks test whether you can move beyond simply remembering facts. They assess your ability to select the right knowledge and apply it to a new scenario. Think of a case study as a puzzle where you already have the tools to solve it.
这些任务考查你是否能够超越简单的记忆事实。它们评估你选择正确知识并将其应用于新情境的能力。可以把案例研究想象成一个谜题，而你已经拥有了解决它的工具。
2. Why Case Studies Matter for Year 7 Students | 为什么案例研究对七年级学生很重要
Case studies bring psychology to life. Instead of only learning about theories from a textbook, you get to see how those theories explain the actions of real people. This deepens your understanding and makes the subject much more memorable.
案例研究让心理学变得生动。你不再只是从课本上学习理论，而是能看到这些理论如何解释真实人物的行为。这能加深你的理解，让这门学科更令人印象深刻。
Furthermore, case analysis is a core skill examined by Edexcel. Marks are awarded for identifying the relevant psychological concept, explaining it accurately, and linking it back to the details of the scenario. Practising this skill regularly will not only boost your exam performance but also sharpen your critical thinking.
此外，案例分析是 Edexcel 考试的核心技能。分数会奖励给识别出相关心理学概念、准确解释并把它与情境细节联系起来的答案。定期练习这项技能不仅能提升你的考试成绩，还能锻炼你的批判性思维。
3. Step-by-Step Guide to Analysing a Case | 案例分析的分步指南
Step 1: Identify the psychological topic. Read the scenario and ask yourself: is this about memory, social influence, child development, or learning? Look for keywords like ‘forget’, ‘peer pressure’, ‘younger child’, or ‘reward’.
第一步：确定心理学主题。 阅读情境并问自己：这是关于记忆、社会影响、儿童发展还是学习？寻找关键词，比如“忘记”、“同伴压力”、“年幼的孩子”或“奖励”。
Step 2: Pick out the key facts. Underline or note down the behaviours and outcomes described in the case. For example, how many items did the person remember? What did the group do? These details will be crucial when you write your explanation.
第二步：找出关键事实。 划出或记下案例中描述的行为和结果。例如，那个人记住了多少个项目？群体做了什么？这些细节在你撰写解释时将至关重要。
Step 3: Select the appropriate theory or study. Decide which psychological model or piece of research best explains the key facts. If the case is about memory capacity, the Multi-Store Model is likely the right choice.
第三步：选择合适的理论或研究。 决定哪个心理学模型或研究最能解释这些关键事实。如果案例是关于记忆容量的，多存储模型可能是正确的选择。
Step 4: Explain using a clear structure. Use the PEEL technique (Point, Evidence, Explanation, Link) to build your paragraphs. Always start your explanation by stating the concept you are applying.
第四步：使用清晰的结构进行解释。 使用 PEEL 技巧（观点、证据、解释、联系）来构建段落。开始时先说明你正在应用的概念。
Step 5: Check you have linked back to the case. Every explanation should end with a sentence that connects the theory back to the specific person or situation in the case. Avoid writing generic definitions without mentioning the scenario.
第五步：检查是否已联系回案例。 每个解释都应以一句话结尾，将理论与案例中的特定人物或情境联系起来。避免写出不与情境挂钩的泛泛定义。
4. Case Example 1: Memory in the Classroom | 案例一：课堂中的记忆
Scenario: Mr. Smith gives his Year 7 students a list of 20 words and asks them to recall as many as they can immediately. On average, the students remember about 7 words. He then asks them to count backwards from 50 in threes for 30 seconds. When they try to recall the words again, the average drops to just 3 words.
情境： 史密斯老师给七年级学生一张包含 20 个单词的列表，要求他们立即回忆尽可能多的单词。学生们平均能记住大约 7 个词。然后，他要求他们以每次减 3 的方式从 50 倒数，持续 30 秒。当他们再次尝试回忆单词时，平均回忆量下降到了仅仅 3 个词。
This straightforward case is ideal for applying the Multi-Store Model of memory. The immediate recall of about 7 items points directly to the capacity of short-term memory (STM).
这个简单的案例非常适合应用记忆的多存储模型。立即回忆起大约 7 个项目直接指向了短时记忆的容量。
5. Applying Concepts: The Multi-Store Model | 应用概念：多存储模型
The Multi-Store Model (Atkinson and Shiffrin) describes memory as consisting of three separate stores: sensory memory, short-term memory and long-term memory. Information moves between them through attention and rehearsal.
多存储模型（阿特金森和希夫林）将记忆描述为由三个独立的存储库组成：感觉记忆、短时记忆和长时记忆。信息通过注意和复述在它们之间移动。
| Feature / 特征 | Sensory Memory 感觉记忆 |
Short-Term Memory 短时记忆 |
Long-Term Memory 长时记忆 |
|---|---|---|---|
| Capacity 容量 |
Very large 非常大 |
7 ± 2 items 7 ± 2 个项目 |
Unlimited 无限 |
| Duration 持续时间 |
0.5 – 2 seconds 0.5 – 2 秒 |
18 – 30 seconds 18 – 30 秒 |
Potentially a lifetime 可能持续一生 |
| Encoding 编码 |
Sense-specific 感官特异 |
Mainly acoustic 主要是听觉 |
Mainly semantic 主要是语义 |
In the classroom example, the words initially enter sensory memory. Because the students pay attention, the information passes into STM. The recall of 7 words matches the model’s claim that STM holds 7±2 items.
在课堂例子中，单词首先进入感觉记忆。因为学生集中了注意，信息便进入短时记忆。回忆起 7 个单词符合该模型关于短时记忆容量为 7±2 个项目的观点。
The counting backwards task acted as an interference. It prevented the students from rehearsing the words, so they could not keep them in STM. After 30 seconds, without rehearsal, the trace decayed and only a few items could be retrieved. This illustrates STM’s limited duration.
倒数任务起到了干扰作用。它阻止了学生对单词进行复述，因此他们无法将单词保持在短时记忆中。30 秒后，由于没有复述，记忆痕迹消退，只能提取出少数几个项目。这说明了短时记忆的有限持续时间。
If the students had been allowed to repeat the words or if the words had been linked to a story, rehearsal could have transferred some information into long-term memory, leading to much better recall later.
如果允许学生重复单词，或者将单词与一个故事联系起来，复述就可能将一些信息转入长时记忆，从而在之后取得好得多的回忆成绩。
6. Case Example 2: Conformity on the Playground | 案例二：操场上的从众行为
Scenario: Jamie notices that a popular group of Year 7 students have all started wearing a specific brand of trainers. Even though Jamie thinks the trainers look awkward, he feels pressure to buy them too. Within a week, most of the year group is wearing the same brand. Jamie says later, ‘I just didn’t want to stand out.’
情境： 杰米注意到一群受欢迎的七年级学生都开始穿某个特定品牌的运动鞋。尽管杰米觉得那双鞋看起来很别扭，他仍感到压力也想买一双。一周内，年级里大多数人都穿上了同样的品牌。杰米后来说：“我只是不想显得与众不同。”
This is a clear example of conformity—a type of social influence where an individual changes their behaviour or opinions to fit in with the majority. Several classic studies help explain Jamie’s actions.
这是一个明显的从众例子——一种个体改变自己的行为或观点以融入大多数的社会影响类型。几个经典研究有助于解释杰米的行为。
Normative social influence occurs when someone conforms because they want to be accepted and avoid rejection. Jamie’s comment about not wanting to stand out is a textbook sign of normative influence. Asch’s line study (1951) showed that even when the majority is clearly wrong, people often conform to avoid feeling uncomfortable.
规范社会影响 发生在某人因为想要被接纳、避免被拒绝而从众时。杰米关于不想显得与众不同的言论正是规范影响的典型迹象。阿希的线段研究（1951）显示，即使多数人明显错误，人们也常常从众以避免感到不适。
In addition, informational social influence may be at play. Students might believe that if the popular group is wearing those trainers, they must be the ‘right’ choice. This is especially common in ambiguous situations where people look to others for guidance.
此外，信息社会影响 也可能在起作用。学生们可能认为，如果受欢迎的那群人都穿着那双运动鞋，那么它一定是“正确”的选择。这在模糊情境中尤其常见，人们会向他人寻求指导。
When writing a case analysis, you should name the type of conformity and link the specific behaviour from the scenario to the explanation. For example: ‘Jamie conformed due to normative social influence because his main motivation was to avoid standing out from the majority of his year group.’
在撰写案例分析时，你应当说出从众的类型，并将情境中的具体行为与解释联系起来。例如：“杰米因为规范社会影响而从众，因为他的主要动机是避免从年级大多数中显得与众不同。”
7. Writing a PEEL Paragraph for Case Studies | 为案例分析撰写 PEEL 段落
A strong answer in Edexcel Year 7 Psychology uses the PEEL structure. This keeps your writing focused and ensures you pick up all the available marks.
一份优秀的 Edexcel 七年级心理学答案会使用 PEEL 结构。这能让你的写作聚焦，确保你获得所有可得的分数。
- Point: State the psychological idea you are going to use.
观点： 陈述你将使用的心理学观点。 - Evidence: Provide a brief piece of evidence from the scenario or from a key study.
证据： 提供来自情境或一个关键研究的简短证据。 - Explanation: Explain how the theory works in more detail, using psychological terminology.
解释： 更详细地解释该理论如何运作，使用心理学术语。 - Link: Relate your explanation directly back to the person or event in the case.
联系： 将你的解释直接联系回案例中的人物或事件。
Here is a PEEL paragraph written for the memory case study:
以下是为记忆案例研究撰写的一个 PEEL 段落：
Point: The students’ immediate recall of about 7 words can be explained by the limited capacity of short-term memory (STM).
Evidence: According to the Multi-Store Model, STM can hold 7±2 items.
Explanation: Because the students were asked to recall the words straight after hearing them, the information was still active in their STM. Rehearsal helped some of them maintain the trace, but the finite capacity meant that only a few items could be held at once.
Link: This is why the average recall in Mr. Smith’s class was around 7, neatly fitting the model’s prediction.
观点： 学生立即回忆起大约 7 个单词可以用短时记忆的有限容量来解释。
证据： 根据多存储模型，短时记忆能够容纳 7±2 个项目。
解释： 因为学生在听到单词后立刻被要求回忆，信息仍在他们的短时记忆中保持活跃。复述帮助部分人维持了记忆痕迹，但有限的容量意味着一次只能容纳少数几个项目。
联系： 这就是为什么史密斯老师班上的平均回忆量大约是 7，正好契合模型的预测。
Notice that the ‘Link’ sentence mentions ‘Mr. Smith’s class’. This is what turns a generic answer into a specific case analysis.
请注意，“联系”句提到了“史密斯老师的班级”。这正是将泛泛的答案转变为具体案例分析的关键。
8. Case Example 3: Piaget’s Conservation Task | 案例三：皮亚杰的守恒任务
Scenario: Lucy is 5 years old. She watches an adult pour the same amount of orange juice into two identical short glasses. Then the adult pours the juice from one of the glasses into a tall, narrow glass. Lucy insists the tall glass now has more juice, even though she saw that no extra juice was added. Her older brother, aged 8, correctly says the two amounts are the same.
情境： 露西 5 岁。她看着一个成年人将等量的橙汁倒入两个相同的矮杯中。然后，成年人将其中一个杯子的果汁倒入一个高而窄的玻璃杯。露西坚持认为高杯子里的果汁更多，尽管她看到没有添加额外的果汁。她 8 岁的哥哥则正确地指出两个量是一样的。
This case allows us to apply Piaget’s theory of cognitive development, specifically the concept of conservation. Conservation is the understanding that quantity remains the same even when appearance changes.
这个案例让我们能够应用皮亚杰的认知发展理论，特别是守恒概念。守恒是指理解即使外观改变，数量仍然保持不变。
Lucy is in the pre-operational stage (ages 2-7). Children at this stage lack the ability to conserve because they focus on only one aspect of a situation, a tendency called centration. Lucy centres on the height of the juice, ignoring the width of the glass. She also lacks reversibility—the idea that an action can be mentally reversed. She cannot imagine pouring the juice back into the original glass to check the quantity.
露西处于前运算阶段（2-7 岁）。这一阶段的孩子缺乏守恒能力，因为他们只关注情境的一个方面，这种倾向称为中心化。露西集中于果汁的高度，忽略了玻璃杯的宽度。她也缺乏可逆性——即在心理上逆转一个动作的能力。她无法想象将果汁倒回原先的杯子来检查数量。
Her 8-year-old brother, however, is in the concrete operational stage (ages 7-11). He can de-centre and consider both height and width. He has also mastered reversibility and therefore correctly judges that the amounts must be equal. When you analyse this case, always mention the name of the stage, define centration, and link it to the child’s exact words or actions in the scenario.
然而，她 8 岁的哥哥处于具体运算阶段（7-11 岁）。他能够去中心化，同时考虑高度和宽度。他也掌握了可逆性，因此正确地判断两个量必然相等。当你分析这个案例时，一定要提到阶段的名称，定义中心化，并将其与情境中孩子的确切话语或行为联系起来。
9. Common Mistakes and How to Avoid Them | 常见错误及如何避免
Mistake 1: Describing the case instead of explaining it. Many students simply retell the story. You must go further and use psychology to explain why the behaviour occurred.
错误 1：描述案例而非解释它。 许多学生仅仅复述故事。你必须更进一步，用心理学解释为什么出现了这种行为。
Mistake 2: The ‘name-drop’ without a link. Writing ‘this is normative social influence’ is not enough. Always explain what that term means and connect it directly to a detail in the case.
错误 2：只提到术语名称而不联系。 写“这是规范社会影响”是不够的。始终要解释该术语的意思并把它直接联系到案例中的一个细节。
Mistake 3: Confusing similar concepts. For example, mixing up ‘short-term memory duration’ with ‘short-term memory capacity’. Before writing, check your notes to ensure you are using the right piece of knowledge.
错误 3：混淆相似的概念。 例如，把“短时记忆持续时间”和“短时记忆容量”搞混。在动笔前，检查笔记以确保你使用了正确的知识点。
Mistake 4: Ignoring the question wording. If the question says ‘explain using the Multi-Store Model’, do not bring in other models like Working Memory unless asked. Stick to the theory named.
错误 4：忽略题目措辞。 如果题目说“使用多存储模型解释”，除非有要求，否则不要引入工作记忆等其他模型。坚持使用点名的理论。
10. Practice Case for You to Try | 供你尝试的练习案例
Scenario: Ms. Brown notices that her Year 7 class is often noisy when they enter the room. She decides to give a ‘star sticker’ to each student who sits down quietly and is ready to learn. After two weeks, almost
