📚 Year 7 CAIE Psychology: High-Frequency Topics and Common Mistake Analysis | Year 7 CAIE 心理学：高频考点与易错题分析
This revision guide explores the most commonly examined areas in Year 7 CAIE Psychology, targeting the mistakes students make again and again. By understanding these pitfalls and consolidating key concepts, you can move from simply recalling facts to applying psychological ideas with confidence in exam-style questions.
本复习指南深入解析 Year 7 CAIE 心理学中最常考的领域，直击学生反复出现的错误。通过吃透这些易错点并夯实核心概念，你将能够从机械记忆转变为自信地运用心理学观点解答考题。
1. Research Methods and Variables | 研究方法与变量
The foundation of any psychology investigation is the clear identification of the independent variable (IV) and the dependent variable (DV). The IV is the factor that the researcher deliberately changes or manipulates. The DV is the factor that is measured to see if it has been affected by the change in the IV.
任何心理学研究的基础都是清晰识别自变量（IV）和因变量（DV）。自变量是研究者故意改变或操纵的因素，而因变量则是被测量以观察是否受自变量变化影响的因素。
A very common error in Year 7 is writing the IV as ‘the results of the experiment’. Students often say ‘the IV is the test scores’, but the test scores are actually what is measured, so they are the DV. Another frequent mistake is forgetting to mention the control variables – the factors kept the same for all participants to ensure a fair test, such as time of day, noise level or instructions given.
Year 7 一个常见错误是把自变量写成“实验的结果”。学生常说“自变量是测试分数”，但测试分数其实是被测量的对象，所以它应是因变量。另一个高频错误是忘记提及控制变量——即为所有参与者保持相同以确保公平测试的因素，比如时间段、噪音水平或给出的指导语。
When answering questions about a study’s aim, do not confuse it with the hypothesis. The aim states the purpose of the investigation, while the hypothesis is a clear, testable prediction that includes both the IV and the DV.
当回答研究目的相关问题时，切勿将其与假设混淆。目的陈述的是调查的宗旨，而假设则是一个清晰、可检验的预测，其中须同时包含自变量与因变量。
2. Experimental Design and Common Design Flaws | 实验设计与常见设计缺陷
The three main experimental designs you need to know are independent groups design, repeated measures design and matched pairs design. In independent groups, different participants are used in each condition of the IV. In repeated measures, the same participants take part in all conditions.
你需要掌握的三种主要实验设计是独立组设计、重复测量设计和配对组设计。在独立组设计中，不同的参与者被分配到自变量的各个条件中。在重复测量设计中，同一批参与者参与所有条件。
A typical mistake is claiming that repeated measures design is ‘better’ because it uses fewer people. While it does control for participant variables, it suffers from order effects – practice or boredom can influence results in the second condition. Many Year 7 explanations miss that counterbalancing is the technique used to combat order effects by varying the sequence of conditions.
一个典型错误是声称重复测量设计“更好”，因为它用的人更少。尽管它能控制参与者变量，但却存在顺序效应的缺陷——练习效应或厌倦感会影响第二个条件下的结果。许多 Year 7 的解释都忽略了平衡法正是用于对抗顺序效应的技术，即通过变化条件的顺序来消除偏差。
For independent groups, students often overlook the problem of participant variables – individual differences between the groups that might affect the DV, not the IV. The solution is random allocation, where every participant has an equal chance of being placed in any condition.
对于独立组设计，学生常忽视参与者变量问题，即组间个体差异可能影响因变量，而非自变量。解决方案是随机分配，让每个参与者都有均等的机会进入任意条件。
3. Ethical Guidelines in Psychological Research | 心理学研究的伦理准则
Studying ethics is a high-frequency topic, especially in scenario-based questions. The four principles you must be able to apply are informed consent, the right to withdraw, confidentiality and protection from harm. Students often lose marks by giving vague answers such as ‘keep it a secret’ instead of citing the term ‘confidentiality’ and explaining how it might be maintained, e.g. using code numbers instead of names.
伦理是高频考点，尤其会出现在情境应用题中。你必须能够运用的四项原则是知情同意权、退出权、保密性与免受伤害的保护。学生常因答案笼统而丢分，比如用“保密”而非专业术语“保密性”，并且未能说明如何维护它，例如用代码编号取代姓名。
Deception is one of the most commonly misunderstood concepts. In Year 7, deception occurs when the true aim of the study is not revealed to participants before they agree to take part. It is only acceptable if the research would be impossible without it and if a full debrief is given afterwards. A typical error is arguing that all deception is wrong – instead, you should discuss the cost–benefit balance.
欺骗是最常被误解的概念之一。在 Year 7 中，欺骗指在参与者同意参加前没有告知研究的真实目的。只有在不欺骗就无法进行研究，且事后提供完整的事后解说的情况下，欺骗才是可接受的。一个典型错误是主张所有欺骗都是错误的——相反，你应讨论成本与收益的平衡。
Always link your ethical answer back to the scenario. Instead of just writing ‘give the right to withdraw’, explain exactly when and how a participant could leave the study without penalty.
无论如何都要将伦理答案与情境联系起来。不要仅仅写“给予退出权”，要确切说明参与者可以何时以及如何无惩罚地离开研究。
4. The Multi-Store Model of Memory | 记忆的多重储存模型
The multi-store model proposes that memory consists of three separate stores: sensory memory, short-term memory (STM) and long-term memory (LTM). Information flows from sensory memory into STM if we pay attention to it, and from STM into LTM through rehearsal.
多重储存模型提出记忆由三个独立的储存库组成：感觉记忆、短时记忆（STM）和长时记忆（LTM）。如果我们对信息加以注意，它就会从感觉记忆进入短时记忆；通过复述，信息再从短时记忆转入长时记忆。
One exam question that traps many Year 7 students concerns the capacity and duration of STM. They often answer ‘7 items’ for both capacity and duration. Capacity refers to how much information can be held – about 7 ± 2 chunks. Duration refers to how long information lasts – around 18–30 seconds without rehearsal. Make sure you never swap these two characteristics.
一道常让 Year 7 学生掉入陷阱的考题是有关短时记忆的容量和持续时间的。他们常把容量和持续时间都答成“7项”。容量指能容纳多少信息——约 7 ± 2 个组块。持续时间指信息能保留多久——若无复述大约 18–30 秒。务必不要混淆这两个特征。
When describing LTM, avoid the common mistake of saying ‘LTM has unlimited capacity and duration for everyone’. While theoretically its capacity is unlimited, retrieval may fail due to interference or lack of cues. Use the correct terms: semantic encoding (meaning) is the main form of encoding in LTM.
在描述长时记忆时，要避免常见错误“每个人的 LTM 都有无限的容量和时长”。虽然理论上容量无限，但由于干扰或缺乏线索可能导致提取失败。应使用正确术语：语义编码（以意义编码）是长时记忆的主要编码形式。
5. Forgetting and Interference Theory | 遗忘与干扰理论
Interference theory explains forgetting in LTM by suggesting that some memories disrupt the retrieval of others. There are two types: proactive interference – when an older memory disrupts the recall of a newer one; and retroactive interference – when a newer memory disrupts the recall of an older one.
干扰理论通过表明某些记忆会干扰其他记忆的提取来解释长时记忆中的遗忘。它包括两类：前摄干扰——旧记忆干扰了新记忆的回忆；倒摄干扰——新记忆干扰了旧记忆的回忆。
The direction of interference is the most frequent source of errors. An easy way to remember is that ‘proactive = past going forward’ (old disrupts new) and ‘retroactive = recent going backward’ (new disrupts old). Under test conditions, many students mix these up when given a simple example like learning two lists of words. Draw a timeline if you are unsure.
干扰的方向是最常见的错误来源。一个简单的记忆方法是“前摄 = 从前向前”（旧的扰乱新的），“倒摄 = 新近向后”（新的干扰旧的）。考试时，很多学生碰到像学习两组词表这类简单例子时就会混淆。如果不确定，就画一条时间线。
Another misconception is to state that interference causes information to vanish from LTM. In reality, the information is still stored but temporarily inaccessible. Be precise: interference reduces the accessibility, not the availability, of memories.
另一个误解是声称干扰会导致信息从长时记忆中消失。实际上信息仍被储存着，只是暂时无法提取。要准确表述：干扰减少的是记忆的可提取性，而非可用性。
6. Visual Perception and Depth Cues | 视觉感知与深度线索
Year 7 CAIE psychology expects you to differentiate between monocular and binocular depth cues. Monocular cues require only one eye – examples include relative size, texture gradient, linear perspective and superimposition. Binocular cues rely on both eyes working together, notably retinal disparity and convergence.
Year 7 CAIE 心理学要求你区分单眼和双眼深度线索。单眼线索只需一只眼——例子包括相对大小、纹理梯度、线条透视和重叠。双眼线索依赖双眼协同工作，主要是视网膜像差和辐合。
A classic exam error is labelling ‘linear perspective’ as a binocular cue because the student imagines two lines converging towards a vanishing point. But linear perspective is a pictorial cue, therefore monocular. Always check whether the cue can be used with one eye covered. If yes, it is monocular.
一个经典的考试错误是把“线条透视”标记为双眼线索，因为学生想象两条线汇聚到一个消失点。但线条透视是图画线索，因此是单眼的。永远要检查这个线索是否能用一只眼睛感知到。如果可以，那就是单眼线索。
When analysing visual illusions such as the Muller-Lyer illusion, avoid describing it as a ‘trick of the brain’ without explanation. Instead, link the illusion to a specific misinterpretation of depth cues – for instance, the outward fins are interpreted as an inside corner of a room, which appears closer, leading the line to be perceived as shorter.
在分析诸如穆勒-莱尔错觉等视错觉时，不要仅仅把它描述为“大脑的欺骗”而不加解释。而应将错觉与对深度线索的特定错误解读联系起来——例如，向外的箭头被解读为房间的内角，看起来更近，导致线条被感知为更短。
7. Piaget’s Theory of Cognitive Development | 皮亚杰的认知发展理论
Piaget’s stage theory is a guaranteed high-weight topic. The stages you must know for Year 7 are the sensorimotor (0–2 years), preoperational (2–7 years) and concrete operational (7–11 years). Make sure you can link key features to the correct stage: object permanence for sensorimotor, egocentrism and animism for preoperational, and conservation and decentration for concrete operational.
皮亚杰的阶段理论是必考的高权重主题。Year 7 必须掌握的阶段是感觉运动阶段（0–2 岁）、前运算阶段（2–7 岁）和具体运算阶段（7–11 岁）。确保你将关键特征与正确阶段对应起来：客体永久性对应感觉运动阶段，自我中心和泛灵论对应前运算阶段，守恒与去中心化对应具体运算阶段。
The single most tested concept is conservation – the understanding that quantity remains the same even when appearance changes. Many students incorrectly say that conservation develops because children ‘get older’, rather than linking it to the logical operation of reversibility. In an exam, you should explain that the child realises the transformation can be mentally reversed.
考察最多的单一概念就是守恒——理解即使外观改变，数量依然保持不变。许多学生错误地说守恒能力的发展仅仅是因为孩子“长大了”，而未能将其与可逆性的逻辑运算联系起来。在考试中，你应解释孩子意识到这种转变可以在脑内逆行。
Another high-risk area is describing egocentrism simply as ‘being selfish’. In Piaget’s framework, it means the child can only see the world from their own point of view, as demonstrated by the three mountains task. So avoid the word ‘selfish’ – use ‘unable to take another person’s perspective’.
另一个高风险区域是把自我中心主义简单描述为“自私”。在皮亚杰的框架里，它指的是孩子只能从自己的视角看世界，正如三山实验所展示的。因此要避免“自私”一词——应使用“无法采取他人的观点”。
8. Social Influence: Conformity and 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. You must be able to differentiate between compliance (publicly agreeing but privately disagreeing) and internalisation (truly accepting the group’s norm). A common slip is using them interchangeably in short-answer questions.
从众是由于真实或想象中的群体压力而导致的行为或信念改变。你必须能够区分顺从（公开同意但私下不同意）和内化（真正接受了群体规范）。常见的疏忽是在简答题中交换使用这两个术语。
When referring to Asch’s line study, do not just state the percentage of participants who conformed. Many Year 7 answers say ‘75% conformed at least once’ but forget to mention that this happened because the task was unambiguous – the confederates gave a clearly wrong answer. This highlights normative social influence, the desire to be liked and accepted.
当提到阿希的线段研究时，不要只说出从众的参与者百分比。许多 Year 7 的答案会说“75% 的人至少从众了一次”，却忘了提这发生在任务答案明确的情况下——同谋给出了明显错误的回答。这突出了规范性社会影响，即渴望被喜欢和接纳。
Obedience is different: it involves following a direct order from an authority figure. Students often misuse the term ‘conformity’ when they mean ‘obedience’. If a teacher tells you to put your phone away and you comply, that is obedience, not conformity, because it is a direct command.
服从则不同：它涉及遵照权威人物的直接指令。学生经常误用“从众”一词来表达“服从”。如果老师让你把手机收起来，你照做了，那是服从，不是从众，因为这是一个直接的命令。
9. Stereotypes, Prejudice and Discrimination | 刻板印象、偏见与歧视
These three concepts are frequently confused. A stereotype is a cognitive simplification – an overgeneralised belief about a group (e.g. ‘all teenagers are rebellious’). Prejudice is the affective, or emotional, component – a negative attitude towards someone based on their group membership. Discrimination is the behavioural component – how you act on prejudice.
这三个概念经常被混淆。刻板印象是一种认知简化——对某个群体的过度概括化的信念（例如“所有青少年都叛逆”）。偏见是情感成分，即基于某人所属群体而产生的负面态度。歧视则是行为成分，即基于偏见采取的行动。
The most common mistake is defining prejudice as an action. Prejudice is an attitude, not a behaviour. In a scenario question, do not label an act of verbal abuse as ‘prejudice’ – call it ‘discrimination’ and then explain that it may be driven by prejudiced attitudes and stereotypic beliefs.
最常见的错误是将偏见定义为一种行为。偏见是态度，不是行为。在情境题中，不要把言语辱骂的行为标为“偏见”——应称之为“歧视”，然后解释它可能由偏见态度和刻板信念驱动。
Year 7 questions also expect you to suggest ways of reducing prejudice. A simple but effective answer is ‘intergroup contact under equal status conditions’, but many students miss the condition ‘equal status’. Without it, contact can reinforce stereotypes.
Year 7 的题目还期望你提出减少偏见的方法。一个简单但有效的答案是“在平等地位条件下进行群体间接触”，但许多学生漏掉了“平等地位”这一条件。没有它，接触反而可能强化刻板印象。
10. Prosocial and Antisocial Behaviour | 亲社会行为与反社会行为
Prosocial behaviour refers to actions intended to help others, such as sharing, cooperating or comforting. Altruism is a purer form of helping where the helper expects no reward. The bystander effect – the tendency for individuals to be less likely to help when others are present – is a high-frequency concept that often appears in multiple-choice and short-answer items.
亲社会行为指旨在帮助他人的行动，例如分享、合作或安慰。利他主义是更纯粹的助人形式，助人者不期待任何回报。旁观者效应——当有其他人在场时个体不太可能提供帮助的倾向——是一个高频概念，常出现在选择题和简答题中。
A common misinterpretation is that the bystander effect means ‘everyone ignored the victim on purpose because they are bad people’. This is not what the theory suggests. Instead, psychological factors like diffusion of responsibility (thinking someone else will help) and pluralistic ignorance (looking to others for cues on how to react) explain the inaction.
一个常见的误解是认为旁观者效应意味着“每个人都故意忽视受害者，因为他们是坏人”。这并非该理论的本意。相反，责任扩散（认为别人会帮忙）和多元无知（观察他人以获取如何反应的线索）等心理因素解释了不作为。
On the antisocial side, the social learning theory of aggression, modelled by Bandura’s Bobo doll experiment, is examined. The most frequent error is to say that children ‘copied exactly what they saw’ without mentioning the cognitive processes of attention, retention, reproduction and motivation. A full answer must link these mediational processes to the observed aggressive acts.
在反社会行为方面，由班杜拉的波波玩偶实验所建模的攻击的社会学习理论会考查到。最常见的错误是说孩子“完全复制了他们看到的东西”，而未提及注意、保持、再现和动机等认知过程。一个完整的答案必须将这些中介过程与观察到的攻击行为联系起来。
11. Introduction to Mental Wellbeing and Stress | 心理健康与压力导论
In the Year 7 syllabus, mental wellbeing is often explored through the lens of stress and coping. Eustress is positive, motivating stress, while distress is negative and overwhelming. Students frequently forget to label stress as a psychological and physiological response to a perceived threat – the stressor.
在 Year 7 教学大纲中，心理健康常常通过压力和应对的视角来探讨。良性应激是积极、有推动力的压力，而劣性应激则是消极且令人不堪重负的。学生经常忘记将压力标记为对感知到的威胁（即压力源）所产生的心理和生理反应。
A classic error occurs when students list coping strategies as either ‘good’ or ‘bad’. Instead, they should be categorised as problem-focused (aimed at tackling the stressor directly, like making a revision timetable) or emotion-focused (aimed at managing the emotional response, like deep breathing or talking to a friend). Avoid value judgments – an emotion-focused strategy is not automatically ‘bad’.
一个经典错误是学生把应对策略简单地列为“好”或“坏”。实际上，它们应被分类为问题导向的应对（旨在直接处理压力源，如制定复习时间表）或情绪导向的应对（旨在管理情绪反应，如深呼吸或与朋友倾诉）。避免做出价值判断——情绪导向的应对策略并不自动等同于“坏”。
When discussing the impact of stress, do not just say ‘stress makes you ill’. Explain briefly the physiological pathway, such as increased heart rate, muscle tension and the release of hormones like adrenaline. This shows a deeper understanding that the exam is looking for.
在讨论压力的影响时，不要只说“压力会让你生病”。简要解释生理通路，例如心率加快、肌肉紧张和肾上腺素等激素的释放。这能体现出考试所要求的更深层理解。
