This article summarises the most tested topics and highlights common mistakes made in assessments, helping you target revision effectively.

在 Year 7 Cambridge 心理学中，学生将探索连接生物学、认知和社会行为的基础概念。理解人们如何思考、感受和行动不仅能满足天生的好奇心，还能培养批判性评价技能。本文总结了最高频的考点，并指出测评中常见的错误，帮助你针对性复习，有效提分。

1. Introduction to Psychology and Research Methods | 心理学简介与研究方法

Psychology is the scientific study of mind and behaviour. It relies on empirical evidence rather than intuition. Key research methods include experiments, observations, interviews, and questionnaires. An independent variable (IV) is what the researcher manipulates, and a dependent variable (DV) is what is measured.

心理学是对心智与行为的科学研究，依赖于实证证据而非直觉。主要研究方法包括实验、观察、访谈和问卷。自变量 (IV) 是研究者操纵的变量，因变量 (DV) 是测量得到的结果。

A common mistake is confusing the IV and DV. Students often write that the IV is the result or fail to identify it in a given scenario. Another pitfall is assuming one research method is always better than another, without considering ethical guidelines such as informed consent, confidentiality, and the right to withdraw.

常见的错误是混淆自变量和因变量。学生们经常误以为自变量是结果，或无法在给定情境中正确识别。另一个陷阱是假设某种研究方法总是优于另一种，却未考虑伦理准则，如知情同意、保密和退出权。

2. Memory: Sensory, Short-Term, and Long-Term Stores | 记忆：感觉记忆、短时记忆与长时记忆

The multi-store model of memory describes three separate stores. Sensory memory holds information for a fraction of a second. Short-term memory (STM) can retain about 7±2 items for around 18–30 seconds without rehearsal. Long-term memory (LTM) has potentially unlimited capacity and duration.

记忆的多重储存模型描述了三个独立的储存系统。感觉记忆将信息保留几分之一秒。短时记忆在不进行复述的情况下可保留约 7±2 个组块，持续 18–30 秒。长时记忆的容量和持续时间几乎无限。

Store	Capacity	Duration
Sensory	Very large	<0.5 seconds
Short-term	7±2 items	18–30 seconds
Long-term	Unlimited	Potentially forever

易错点：学生常把短时记忆的容量和长时记忆的混淆，或在应用题中误认为没有复述时信息会直接进入长时记忆。此外，感觉记忆常被忽略，需要注意它的回声记忆和图像记忆两种类型。

2. Memory: Sensory, Short-Term, and Long-Term Stores | 记忆：感觉记忆、短时记忆与长时记忆

The multi-store model of memory describes three separate stores. Sensory memory holds information for a fraction of a second. Short-term memory (STM) can retain about 7±2 items for around 18–30 seconds without rehearsal. Long-term memory (LTM) has potentially unlimited capacity and duration.

记忆的多重储存模型描述了三个独立的储存系统。感觉记忆将信息保留几分之一秒。短时记忆在不进行复述的情况下可保留约 7±2 个组块，持续 18–30 秒。长时记忆的容量和持续时间几乎无限。

Store	Capacity	Duration
Sensory	Very large	<0.5 seconds
Short-term	7±2 items	18–30 seconds
Long-term	Unlimited	Potentially forever

A classic error is mixing up the capacity of STM with that of LTM in application questions. Students also mistakenly think that without rehearsal, information automatically enters LTM. Sensory memory is often overlooked — remember it includes iconic (visual) and echoic (auditory) forms.

经典错误是在应用题中将短时记忆的容量和长时记忆的混淆。学生们还错误地认为，如果没有复述，信息会自动进入长时记忆。感觉记忆经常被忽略——记住它包括图像记忆（视觉）和回声记忆（听觉）两种形式。

3. Forgetting: Decay and Interference | 遗忘：消退与干扰

Forgetting occurs due to decay (memory trace fades over time) or interference (other information blocks retrieval). Proactive interference happens when old learning disrupts new recall; retroactive interference is when new learning disrupts old recall. Ebbinghaus’s forgetting curve shows rapid forgetting soon after learning, then a plateau.

遗忘因消退（记忆痕迹随时间变淡）或干扰（其他信息阻碍提取）而发生。前摄抑制是指旧知识干扰新信息的回忆；倒摄抑制是新知识干扰旧信息的回忆。艾宾浩斯遗忘曲线表明，学习后短时间内遗忘最快，随后趋于平缓。

Pitfall: Students often label any forgetting as ‘decay’ without considering interference. In multiple-choice questions, they confuse proactive and retroactive interference. Remember: proactive = forward-acting (old → new), retroactive = backward-acting (new → old).

易错点：学生常把所有遗忘都归为“消退”，而不考虑干扰。在选择题中，他们容易混淆前摄抑制和倒摄抑制。记住：前摄抑制 = 向前作用（旧→新），倒摄抑制 = 向后作用（新→旧）。

4. Piaget’s Stages of Cognitive Development | 皮亚杰的认知发展阶段

Jean Piaget proposed four stages: sensorimotor (0–2 years), pre-operational (2–7 years), concrete operational (7–11 years), and formal operational (11+ years). In Year 7, pupils are transitioning from concrete to formal operations. Key achievements include conservation, classification, and logical thought about concrete events.

让·皮亚杰提出四个阶段：感觉运动阶段（0–2岁），前运算阶段（2–7岁），具体运算阶段（7–11岁）和形式运算阶段（11岁以上）。Year 7 学生正从具体运算向形式运算过渡。主要成就是获得守恒、分类能力，以及关于具体事件的逻辑思维。

High-frequency errors include: applying a stage to the wrong age range, forgetting that conservation means understanding that quantity remains the same despite appearance changes, and assuming all adolescents reach formal operations simultaneously. Also, students sometimes claim pre-operational children can think logically, which is incorrect due to egocentrism and lack of reversibility.

高频错误包括：将某个阶段应用于错误的年龄段，忘记守恒意味着理解数量不随外观改变而变化，以及假设所有青少年同时达到形式运算。此外，学生有时声称前运算儿童能进行逻辑思考，这是不正确的，因为该阶段存在自我中心主义和缺乏可逆性。

5. Conformity and Social Influence | 从众与社会影响

Asch’s line experiment demonstrated that people often conform to a majority even when the answer is clearly wrong. Normative influence occurs when we want to be liked; informational influence occurs when we believe the group has better knowledge. The size of the majority is a key factor — conformity increases with group size up to about 3–5 people.

阿希的线段实验表明，即使答案明显错误，人们也常常顺从多数。规范影响发生在我们希望被喜欢时；信息影响发生在我们认为群体拥有更佳知识时。多数人的规模是关键因素——从众行为随群体人数增加而增加，直到大约3–5人。

Common mistake: mixing up normative and informational influence. Students often state that Asch’s participants conformed because they thought the group was correct (informational), but Asch’s follow-up interviews revealed they knew the answer was wrong yet conformed to avoid ridicule (normative). Another error is forgetting that conformity can be lowered by having one ally who gives the correct answer.

常见错误：混淆规范影响和信息影响。学生常说阿希实验中的参与者从众是因为他们以为群体是正确的（信息影响），但阿希的后续访谈显示，他们知道答案是错的，却为了避免嘲笑而从众（规范影响）。另一个错误是忘记只要有一个盟友给出正确答案，从众行为就会减少。

6. Brain Structure and Function | 大脑结构与功能

The cerebral cortex is divided into four lobes: frontal (decision-making, personality), parietal (sensory information, spatial awareness), occipital (vision), and temporal (hearing, memory). The brain stem controls vital functions like breathing. The limbic system, including the amygdala and hippocampus, manages emotion and memory.

大脑皮层分为四个叶：额叶（决策、人格），顶叶（感觉信息、空间意识），枕叶（视觉）和颞叶（听觉、记忆）。脑干控制呼吸等生命功能。边缘系统，包括杏仁核和海马体，管理情绪和记忆。

Lobe	Primary Function
Frontal	Reasoning, planning, personality
Parietal	Touch, temperature, pain
Occipital	Vision
Temporal	Hearing, language comprehension

A repeated error is placing the visual cortex in the parietal lobe or claiming the temporal lobe is responsible for movement. Using the mnemonic ‘F-POT’ (Frontal, Parietal, Occipital, Temporal) can help avoid these mistakes. Also, remember that the left hemisphere controls the right side of the body and vice versa.

屡犯的错误是把视觉皮层放到顶叶，或者声称颞叶负责运动。使用助记符 ‘F-POT’（额、顶、枕、颞）有助于避免这些错误。此外，记住左脑控制右侧身体，反之亦然。

7. Emotions, Motivation, and Maslow’s Hierarchy | 情绪、动机与马斯洛需求层次

Maslow’s hierarchy of needs suggests that basic physiological needs must be satisfied before higher needs like belonging, esteem, and self-actualisation. Emotions often involve physiological arousal (e.g., heart rate increase), expressive behaviour (smiling), and conscious experience. The James-Lange theory proposes that physiological arousal precedes the emotional experience.

马斯洛的需求层次表明，必须首先满足基本的生理需求，才能追求更高层次的需求，如归属感、尊重和自我实现。情绪通常涉及生理唤醒（如心率加快）、表达行为（微笑）和主观体验。詹姆斯-兰格理论认为身体唤醒先于情绪体验发生。

Frequent pitfall: students assume self-actualisation is easy to reach, forgetting that the lower levels must be met first. In exam questions, they often misinterpret the order: safety needs come before love/belonging. Also, they confuse James-Lange with the Cannon-Bard theory, which states arousal and emotion occur simultaneously.

常见陷阱：学生以为自我实现很容易达到，却忘了必须先满足低层次需求。考题中，他们经常误解顺序：安全需求在爱与归属之前。此外，他们会将詹姆斯-兰格理论与坎农-巴德理论混淆，后者认为唤醒与情绪同时发生。

8. Experimental Design and Variables | 实验设计与变量

A well-designed experiment controls extraneous variables to establish cause and effect. Independent measures design uses different participants in each condition, while repeated measures uses the same participants. A confounding variable is one that varies systematically with the IV, potentially misleading results. Operationalisation means clearly defining how variables are measured.

设计良好的实验通过控制额外变量来确定因果关系。独立组设计在每个条件下使用不同的参与者，而重复测量设计使用同一批参与者。混淆变量是与自变量系统性地一起变化、可能误导结果的变量。操作化意味着明确界定如何测量变量。

Major mistakes: calling a confounding variable an extraneous variable when it actually affects the DV systematically. Also, students often forget to operationalise variables in exam answers, writing vague phrases like ‘measure memory’ instead of ‘number of words recalled correctly from a list of 20’.

主要错误：当混淆变量系统性地影响因变量时，却称其为额外变量。此外，学生在考试答案中经常忘记操作化变量，写“测量记忆”这种模糊表述，而不是“从20个词中正确回忆出的单词数量”。

9. Mental Health, Stigma, and Stereotypes | 心理健康、污名化与刻板印象

Mental health refers to our emotional, psychological, and social well-being. Common disorders introduced at this level include anxiety and depression. Stigma involves negative attitudes and discrimination towards those with mental health conditions. Stereotypes are oversimplified beliefs about a group, which can lead to prejudice.

心理健康指我们的情绪、心理和社交健康。在该年级阶段接触的常见障碍包括焦虑症和抑郁症。污名化涉及对有心理健康问题的人持有负面态度和歧视。刻板印象是对某一群体的过度简化信念，可能导致偏见。

Error-prone areas: confusing stress with anxiety (stress is a response to a specific stressor, anxiety can be vague and persistent), or assuming all stereotypes are negative (they can be positive but still limiting). Also, students may provide a single label without explaining the impact of stigma, such as reluctance to seek help.

易错领域：混淆压力与焦虑（压力是对特定压力源的反应，焦虑可能是模糊且持久的），或者假设所有刻板印象都是负面的（有些可以是正面的但仍然有局限性）。学生也可能只给出标签，却不解释污名化的影响，比如导致不愿寻求帮助。

10. Stress and Coping Strategies | 压力与应对策略

Stress is the body’s reaction to perceived threat, activating the fight-or-flight response via the sympathetic nervous system. Coping can be problem-focused (addressing the stressor directly) or emotion-focused (managing feelings). Social support is a protective factor that buffers against negative effects of stress.

压力是身体对感知到的威胁的反应，通过交感神经系统激活战或逃反应。应对策略可分为问题焦点应对（直接处理压力源）和情绪焦点应对（管理感受）。社会支持是一个保护因素，能缓冲压力的负面影响。

Common pitfalls: failing to distinguish between acute and chronic stress, or thinking that avoidance is a healthy emotion-focused strategy (it is usually maladaptive). Another error is saying ‘stress is always bad’ — a moderate level of stress can enhance performance (Yerkes-Dodson law).

常见陷阱：无法区分急性压力和慢性压力，或认为回避是一种健康的情绪焦点策略（它通常是不适应的）。另一个错误是说“压力总是不好的”——适度的压力可以提升表现（耶克斯-多德森定律）。

11. Language, Thought, and Problem Solving | 语言、思维与问题解决

Language helps us structure and express thoughts. Problem-solving can be hindered by functional fixedness (inability to see an object used beyond its typical function) and mental set (sticking to a strategy that worked in the past). Insight involves a sudden realisation of a solution.

语言帮助我们组织和表达思想。问题解决可能受到功能固着（无法看到物品超出其典型功能的用途）和心向（坚持过去有效的策略）的阻碍。顿悟涉及突然意识到解决方案。

Typical exam mistake: describing a mental set as ignorance, rather than an inability to switch strategies. Also, students confuse functional fixedness with lack of creativity — it is specifically about object use. When given a scenario, they must identify the exact cognitive obstacle.

典型考试错误：将心向描述为无知，而不是无法切换策略。此外，学生将功能固着与缺乏创造力混淆——它特指物品的用途。在给定情境中，他们必须准确识别认知障碍的类型。

12. Attachment and Early Social Development | 依恋与早期社会性发展

Attachment is the emotional bond between an infant and caregiver. Mary Ainsworth’s Strange Situation identified secure, insecure-avoidant, and insecure-resistant attachment styles. Imprinting, studied by Lorenz, showed that some animals form strong attachments during a critical period shortly after birth.

依恋是婴儿与照顾者之间的情感纽带。玛丽·安斯沃斯的陌生情境实验识别出安全型、不安全-回避型和不安全-矛盾型依恋风格。洛伦茨研究的印刻现象表明，一些动物在出生后不久的关键期内会形成强烈依恋。

Frequent errors: mislabelling a child who ignores the caregiver on reunion as ‘secure’ when that is actually avoidant behaviour. Students also confuse critical and sensitive periods — a critical period is a fixed time window, while a sensitive period is a longer span when development is optimal but not impossible later.

常见错误：把重聚时忽略照顾者的孩子标记为“安全型”，而这实际上是回避型行为。学生还会混淆关键期和敏感期——关键期是固定的时间窗口，敏感期是一段较长的最佳发展期，但过后仍有可能发展。
