📚 High-Frequency Topics and Common Mistakes in Year 7 Cambridge Psychology | Year 7 Cambridge 心理学：高频考点与易错题分析

Psychology in Year 7 introduces you to the fascinating scientific study of mind and behaviour. From understanding how memory works to exploring why people conform, the Cambridge curriculum builds a strong foundation. However, many students lose marks not because they lack knowledge, but because they fall into predictable traps. This article maps out the most tested topics and dissects the common errors, helping you turn mistakes into marks. Let’s dive into the high-frequency areas and learn how to avoid the typical pitfalls.

七年级心理学为你打开了用科学方法研究心理与行为的迷人世界。从理解记忆如何运作到探索人们为何会从众，剑桥课程会为你打下坚实的基础。然而，许多学生丢分并不是因为知识欠缺，而是掉入了可预见的陷阱。本文梳理了最高频的考点，并剖析了常见错误，助你化失分为得分。让我们一起进入这些高频领域，学习如何避开典型错误。

1. What is Psychology? | 什么是心理学？

Psychology is the scientific study of the mind and behaviour. It uses empirical methods to observe, measure, and explain why we think, feel, and act the way we do. A common mistake in Year 7 is defining psychology too broadly as ‘the study of people’ or confusing it with psychiatry. Remember, psychologists do not prescribe medication; they use research and therapy. You should be able to distinguish psychology from common sense – it relies on evidence, not just intuition.

心理学是对心理和行为的科学研究。它使用实证方法来观察、测量和解释我们思考、感受和行动的原因。七年级常见的错误是将心理学定义得过于宽泛，说成“研究人的学问”，或将其与精神病学混淆。请记住，心理学家不开处方药；他们运用研究和心理疗法。你应该能够区分心理学与常识——心理学依赖证据，而不仅仅是直觉。

Tip: Use the phrase ‘scientific study of mind and behaviour’ in your definition.
提示：在定义中使用“对心理和行为的科学研究”这个表述。

2. Research Methods: Independent and Dependent Variables | 研究方法：自变量与因变量

Every experiment has an independent variable (IV) – the factor the researcher changes or manipulates – and a dependent variable (DV) – the factor that is measured. A high-frequency exam question asks you to identify the IV and DV in a scenario. The most common error is mixing them up. For example, if a study tests whether background music affects test scores, the IV is the presence or type of music, and the DV is the test score. Never write ‘the music changes’ as the DV; the DV must be the measurable outcome.

每个实验都有自变量（IV）——研究者改变或操纵的因素——和因变量（DV）——被测量的因素。考试中高频出现让你在某个情境中识别自变量和因变量的题目。最常见的错误就是把两者弄反。例如，如果一项研究测试背景音乐是否影响考试成绩，那么自变量是音乐的存在与否或类型，因变量是考试分数。千万不要把“音乐改变了”写成因变量；因变量必须是可测量的结果。

Independent Variable (IV)	Dependent Variable (DV)
What you change	What you measure
Cause	Effect

3. Experimental Design: Independent Groups vs Repeated Measures | 实验设计：独立组与重复测量

Experimental design refers to how participants are allocated to conditions. In independent groups design, different participants take part in each condition. In repeated measures, the same participants do all conditions. A classic mistake is thinking that repeated measures eliminates individual differences; it actually controls for them, but it can cause order effects (practice or fatigue). Students often confuse these designs with the variables themselves. Remember, design describes participant allocation, not the IV.

实验设计指的是如何将参与者分配到不同的实验条件中。在独立组设计中，不同的参与者参加不同的条件。在重复测量设计中，同一批参与者完成所有条件。一个经典错误是认为重复测量可以消除个体差异；实际上它控制了（但未消除）个体差异，并且可能导致顺序效应（练习效应或疲劳）。学生经常将这些设计与变量本身混淆。请记住，设计描述的是参与者的分配方式，而不是自变量。

Independent groups: more participants needed; no order effects.
Repeated measures: fewer participants; may need counterbalancing.
独立组：需要更多参与者；无顺序效应。
重复测量：参与者较少；可能需要平衡顺序。

4. Memory: The Multi-Store Model | 记忆：多存储模型

Atkinson and Shiffrin’s multi-store model describes three stores: sensory register, short-term memory (STM), and long-term memory (LTM). Information enters the sensory register and, if paid attention to, moves to STM. Through rehearsal, it can be transferred to LTM. A frequent mistake is misstating STM capacity or duration. STM holds about 7±2 items and lasts up to 30 seconds without rehearsal. Students often say STM holds 5-9 items and lasts for minutes – that is incorrect. Use accurate figures.

阿特金森和谢夫林的多存储模型描述了三个存储库：感觉登记器、短时记忆（STM）和长时记忆（LTM）。信息进入感觉登记器，如果被注意，则会进入短时记忆。通过复述，它可以被转入长时记忆。一个常犯错误是记错短时记忆的容量或持续时间。短时记忆大约容7±2个项目，在不复述的情况下最多保持30秒。学生常说短时记忆容量5-9个项目，并保持几分钟——这是不正确的。请使用准确数字。

Sensory Register → Attention → STM → Rehearsal → LTM

5. Common Mistakes: Serial Position Effect | 易错点：系列位置效应

When recalling a list, people tend to remember the first items (primacy effect) and the last items (recency effect). This is the serial position effect. The primacy effect is due to LTM rehearsal; the recency effect is due to STM still holding the last items. A common trap is stating that the recency effect proves LTM rehearsal. It does not. Another mistake is failing to explain why a delay with a distractor task wipes out the recency effect – it prevents STM rehearsal. You must link the effect to the correct memory store.

在回忆一个列表时，人们往往能记住开头的项目（首因效应）和末尾的项目（近因效应）。这就是系列位置效应。首因效应是由于长时记忆中的复述；近因效应是由于短时记忆仍然保留着最后几个项目。一个常见陷阱是说近因效应证明了长时记忆的复述。它并没有。另一个错误是未能解释为什么带有干扰任务的延迟会消除近因效应——它阻止了短时记忆复述。你必须将这个效应与正确的记忆存储联系起来。

Primacy → LTM
Recency → STM
首因效应 → 长时记忆
近因效应 → 短时记忆

6. Social Influence: Conformity vs Obedience | 社会影响：从众与服从

Conformity is a change in behaviour or belief due to real or imagined group pressure. Obedience is following a direct order from an authority figure. The distinction is a high-frequency question. Students often use examples interchangeably and fail to mention the key element: Conformity does not require an explicit command, while obedience does. For example, Asch’s line study demonstrates conformity; Milgram’s shock experiment illustrates obedience. Always identify the presence (or absence) of a direct order.

从众是指由于真实的或想象到的群体压力而改变行为或信念。服从是听从权威人物的直接命令。这一区别是高频考题。学生经常混用例子，并且没有提到关键要素：从众不需要明确的指令，而服从需要。例如，阿希的线条研究展示的是从众；米尔格拉姆的电击实验展示的是服从。务必识别是否存在直接命令。

7. Factors Affecting Conformity | 影响从众的因素

Several factors influence conformity levels: group size, unanimity, task difficulty, and culture. An easy mistake is to write that conformity increases indefinitely with group size. Research shows conformity rises sharply up to about 3-5 group members and then levels off. Another error is neglecting the role of a dissenter (someone who breaks unanimity); even one dissenter dramatically reduces conformity. When answering exam questions, be specific: ‘a larger group increases conformity, but only up to a point.’

有几个因素会影响从众程度：群体大小、一致性、任务难度和文化。一个简单错误是写从众会随群体规模的增大而无限增加。研究表明，从众在群体达到约3-5人时急剧上升，随后趋于平稳。另一个错误是忽略了异议者（打破一致性的人）的作用；哪怕只有一个异议者，也会戏剧性地降低从众行为。在答题时要具体：“更大的群体会增加从众，但仅限于一定程度。”

8. The Brain and Behaviour: Localisation of Function | 大脑与行为：功能定位

The idea that different brain areas perform specific functions is called localisation. For Year 7, you need to know the basic roles: frontal lobe (thinking, planning), temporal lobe (hearing, memory), occipital lobe (vision), and parietal lobe (touch, spatial awareness). A common mistake is confusing Broca’s area (speech production) with Wernicke’s area (language comprehension). Remember: Broca’s is about speaking; damage leads to broken speech. Wernicke’s is about understanding; damage leads to fluent but meaningless speech.

不同脑区执行特定功能这一观念被称为功能定位。对七年级来说，你需要了解各脑叶的基本作用：额叶（思维、计划）、颞叶（听觉、记忆）、枕叶（视觉）和顶叶（触觉、空间感知）。一个常见错误是将布罗卡区（言语产生）与韦尼克区（语言理解）混淆。记住：布罗卡区管说话；损伤导致断断续续的言语。韦尼克区管理解；损伤导致流利却无意义的言语。

9. Sensation and Perception: Visual Illusions | 感觉与知觉：视错觉

Sensation is the detection of stimuli by sensory receptors; perception is how the brain interprets those sensations. Visual illusions occur when perception does not match physical reality. The Muller-Lyer illusion, for example, is often misunderstood. Students incorrectly state it is due to depth cues from everyday life – actually, one explanation is the misapplication of size constancy based on perceived distance. You need to mention that our brain uses prior knowledge (top-down processing), which can sometimes mislead us.

感觉是感受器对刺激的探测；知觉是大脑对这些感觉的解读。当知觉与现实物理世界不一致时，就会产生视错觉。例如，穆勒-莱耶错觉常被误解。学生错误地认为它是由于日常生活中的深度线索——实际上，一种解释是基于感知距离的大小恒常性误用。你需要提到，我们的大脑使用了先前知识（自上而下加工），而它有时会误导我们。

10. Key Study: Asch’s Conformity Experiment | 经典研究：阿希从众实验

Asch (1951) asked participants to match line lengths in a group of confederates who purposely gave wrong answers. About 75% of participants conformed at least once. A high-frequency error is misreporting the percentage or claiming everyone conformed in every trial. The correct figure is that on the critical trials, participants conformed about 37% of the time. Another mistake is forgetting the control condition: when alone, errors were less than 1%, showing the power of group pressure. Always reference the baseline accuracy.

阿希（1951）要求参与者在由一群故意给出错误答案的假被试组成的组里，匹配线段长度。大约75%的参与者至少从众了一次。一个高频错误是误报百分比或声称所有人在每个试验中都从众了。正确的数字是，在关键试验中，参与者约37%的时间表现出了从众。另一个错误是忘记控制条件：独自一人时错误率低于1%，这显示了群体压力的力量。务必提及基线准确度。

11. Applying Knowledge: Exam-Style Questions | 知识应用：考试题型分析

Exam questions often present a short scenario and ask you to apply psychological concepts. For instance, ‘Explain why Sarah might remember the first and last items on her shopping list but forget the middle.’ Students often lose marks by simply naming the serial position effect without elaboration. You must explain that the first items were rehearsed into LTM (primacy) and the last items were still in STM (recency). Linking explanation to evidence is where marks lie. Practice structuring answers: state, define, apply, conclude.

考试题常常给出一个简短情境，要求你应用心理学概念。例如，“解释为什么莎拉可能记得购物清单上的第一个和最后一个项目，却忘记了中间的项目。”学生常常因为只是说出系列位置效应的名称而不加详细阐述而丢分。你必须解释第一个项目是通过复述进入了长时记忆（首因效应），最后几个项目还留在短时记忆（近因效应）。将解释与证据联系起来，才是得分点。练习答案结构：陈述、定义、应用、总结。

12. Tips for Avoiding Mistakes | 避免错误的技巧

To conquer common mistakes, you need a strategy. First, underline command words: identify, explain, compare. Second, use precise terminology – never write ‘short memory’ when you mean ‘short-term memory’. Third, always check the unit of measurement: STM duration is seconds, not minutes. Fourth, when comparing, use linking phrases like ‘whereas’ or ‘on the other hand’. Fifth, practise drawing labelled diagrams of the multi-store model. A final tip: read feedback from past exercises, as errors tend to repeat.

要攻克常见错误，你需要一套策略。首先，圈出指令词：识别、解释、比较。第二，使用精确术语——当你说短时记忆时，绝不要漏掉“时”字。第三，始终检查计量单位：短时记忆持续以秒计，而非分钟。第四，做比较时，使用连接短语，如“而”或“另一方面”。第五，练习绘制带有标签的多存储模型图。最后一个技巧：仔细阅读过往练习的反馈，因为错误往往会重复。
