For Year 10 students tackling CAIE Psychology, knowing what to study is only half the battle. The other half is learning how to avoid the small slips that cost big marks. This article breaks down the most tested topics and the errors that examiners see year after year. Whether you are preparing for end-of-year mocks or simply building strong foundations, these insights will sharpen your revision.
对于 Year 10 学习 CAIE 心理学的学生来说，知道该学什么只是成功的一半。另一半是学会如何避免那些代价高昂的小错误。本文梳理了最高频的考点以及考官年复一年看到的典型差错。无论你是在准备期末模考还是夯实基础，这些分析都能让你的复习更精准。
1. Research Methods: IV, DV and Controls | 研究方法：自变量、因变量与控制变量
Identifying independent variables (IV), dependent variables (DV) and control variables is a skill tested in almost every paper. You must be able to pick them out from a research scenario and explain why each matters. High-frequency exam questions ask: 'Identify the IV in this study' or 'Suggest one variable that should have been controlled.'
识别自变量（IV）、因变量（DV）和控制变量是几乎每张试卷都考的技能。你必须能从研究情境中找出它们并解释其重要性。高频考题会问：“指出本研究中的自变量”或“建议一个应该控制的变量”。
Common Mistake 1: Swapping IV and DV. Students often write that the thing being measured is the IV. In Andrade (2010), some thought doodling was the DV because it was the activity. Actually, the IV was whether participants doodled or not, and the DV was their performance on a surprise memory test.
常见错误1：将自变量与因变量混淆。学生常把被测量的东西当作自变量。在 Andrade (2010) 研究中，有人认为涂鸦是因变量，因为那是一项活动。实际上，自变量是参与者是否涂鸦，而因变量是他们在意外记忆测试中的表现。
Common Mistake 2: Ignoring the importance of operationalisation. Variables must be stated in a way that is measurable. For example, 'aggression' must be defined as 'number of times the child hit a doll' rather than left vague. Without operationalisation, a study cannot be replicated reliably.
常见错误2：忽视操作化的重要性。变量必须以可测量的方式表述。例如，“攻击性”必须定义为“儿童击打玩偶的次数”，而非含糊其辞。缺少操作化，研究就无法可靠复制。
2. Experimental Designs and Ethical Guidelines | 实验设计与伦理准则
CAIE expect you to compare independent groups, repeated measures and matched pairs designs, and to link them to real studies. Ethical guidelines (informed consent, right to withdraw, protection from harm, confidentiality) are equally high-frequency, often appearing in 'Discuss the ethical issues' questions.
CAIE 期望你能比较独立组、重复测量和配对设计，并将它们与实际研究联系起来。伦理准则（知情同意、退出权、免受伤害、保密）同样是高频考点，常出现在“讨论伦理问题”类题目中。
Common Mistake 1: Confusing field and natural experiments. In a field experiment, the researcher still manipulates the IV in a natural setting (e.g., Piliavin et al.'s subway study). In a natural experiment, the IV is naturally occurring (e.g., comparing a town that already had television with one that did not). Treating a natural experiment as a field experiment loses marks.
常见错误1：混淆现场实验与自然实验。在现场实验中，研究者仍在自然环境中操纵自变量（例如 Piliavin 等人的地铁研究）。而在自然实验中，自变量是自然发生的（例如比较已有电视的小镇和没有电视的小镇）。把自然实验当作现场实验会失分。
Common Mistake 2: Believing that a signed consent form makes a study fully ethical. Ethical practice is about the whole process. Even with consent, participants must still be able to withdraw at any time, and deception must be justified by a thorough debrief. Citing only one guideline rarely earns top marks.
常见错误2：认为签署了同意书就代表研究完全合乎伦理。伦理实践关乎整个过程。即使有同意书，参与者依然要能随时退出，且欺骗必须通过充分的事后解释来正当化。只引用一项准则很少能拿到高分。
3. Memory: Multi-Store Model and Working Memory | 记忆：多存储器模型与工作记忆
Atkinson & Shiffrin's (1968) multi-store model and Baddeley & Hitch's (1974) working memory model are cornerstones of the cognitive approach. You need to describe the components (sensory register, STM, LTM; central executive, phonological loop, visuospatial sketchpad) and discuss supporting studies like Peterson & Peterson (1959) or Baddeley (1966).
Atkinson 和 Shiffrin (1968) 的多存储器模型与 Baddeley 和 Hitch (1974) 的工作记忆模型是认知取向的基石。你需要描述各个成分（感觉登记、短时记忆、长时记忆；中央执行系统、语音回路、视空间画板），并讨论支持性研究，如 Peterson & Peterson (1959) 或 Baddeley (1966)。
Common Mistake 1: Treating STM as just a passive store. The multi-store model suggests STM is a temporary holding space, but the working memory model demonstrates it is an active processor. Students sometimes mix up the two, stating that STM has a 'central executive', which belongs to working memory.
常见错误1：将短时记忆仅仅当作被动存储器。多存储器模型视短时记忆为暂时存放处，但工作记忆模型表明它是一个主动加工系统。学生有时将两者混淆，声称短时记忆有“中央执行系统”，那属于工作记忆。
Common Mistake 2: Overgeneralising Miller's magic number. Miller (1956) found that the capacity of STM is about 7 +/- 2 chunks, but chunking depends on meaningful grouping. Students often forget that capacity can be increased through rehearsal and that duration (Peterson & Peterson) is separate from capacity.
常见错误2：过度泛化 Miller 的神秘数字。Miller (1956) 发现短时记忆容量约为 7±2 个组块，但组块化依赖于有意义的分组。学生常忘记容量可通过复述增大，且持续时间（Peterson & Peterson 研究）与容量是两回事。
4. Social Influence: Conformity, Obedience and Bystander Effect | 社会影响：从众、服从与旁观者效应
Asch (1951, 1955) on conformity, Milgram (1963) on obedience and Latané & Darley (1968) on bystander intervention form a triple threat in the social approach. Examiners test both the procedures and the factors that affect these behaviours, such as group size, unanimity, proximity of authority, and diffusion of responsibility.
Asch (1951,1955) 的从众研究、Milgram (1963) 的服从研究与 Latané 和 Darley (1968) 的旁观者介入构成了社会取向的三大重点。考官的考查既包括实验程序，也包括影响这些行为的因素，例如群体规模、一致性、权威接近度以及责任分散。
Common Mistake 1: Using obedience terms to describe conformity. Asch's participants conformed because of group pressure, not because an authority figure commanded them. Students sometimes write: 'Participants obeyed the group,' which is conceptually wrong—obedience requires a direct order from an authority.
常见错误1：用服从术语描述从众。Asch 实验中的参与者因群体压力而从众，并非因为权威人物的命令。学生有时写道：“参与者服从了群体”，这在概念上是错误的——服从需要来自权威的直接指令。
Common Mistake 2: Assuming that Milgram's participants were all sadistic. Milgram's work highlights the power of the situation. A common error is to explain obedience solely through dispositional factors (e.g., 'they were aggressive') without mentioning the agentic state or the situational pressures created by the experimenter's presence.
常见错误2：假定 Milgram 实验中的参与者都是施虐狂。Milgram 的研究强调的是情境的力量。常见的错误是仅用性情因素（例如“他们具有攻击性”）解释服从，而不提及代理状态或由实验者在场造成的情境压力。
5. Development: Attachment and Piaget's Stages | 发展心理学：依恋与皮亚杰阶段
Ainsworth's Strange Situation (secure, insecure-avoidant, insecure-resistant) and Piaget's stages (sensorimotor, pre-operational, concrete operational, formal operational) are heavily examined. Understand the key behaviours in each attachment type and the cognitive milestones, such as object permanence and conservation.
Ainsworth 的奇怪情境（安全型、不安全回避型、不安全矛盾型）以及 Piaget 的阶段（感知运动、前运算、具体运算、形式运算）是高频考查内容。要理解每种依恋类型的关键行为和认知里程碑，如客体永久性与守恒。
Common Mistake 1: Mixing up conservation and object permanence. Object permanence develops during the sensorimotor stage (around 8-12 months) and means a child knows objects exist when hidden. Conservation (understanding that quantity remains the same despite changes in appearance) develops in the concrete operational stage, much later. Students often place conservation in the pre-operational stage.
常见错误1：混淆守恒与客体永久性。客体永久性在感知运动阶段（约 8-12 个月）发展，指儿童知道物体被藏起来时依然存在。守恒（理解数量不随外观变化而改变）则在具体运算阶段才出现，晚得多。学生常把守恒放在前运算阶段。
Common Mistake 2: Describing avoidant attachment as just 'shy'. In the Strange Situation, an avoidant infant shows little distress when the caregiver leaves and avoids contact upon return. Mistaking this for a simple shy temperament overlooks the organised pattern of caregiver interaction linked to insensitive parenting.
常见错误2：把回避型依恋仅仅描述为“害羞”。在奇怪情境中，回避型婴儿在照顾者离开时几乎不表现出痛苦，并在重聚时回避接触。把这误认为单纯的害羞气质，就忽略了与不敏感教养方式相关的有组织的互动模式。
6. Biopsychology: Neurons, Synaptic Transmission and Brain Areas | 生物心理学：神经元、突触传递与脑区
You must be able to label a motor, relay or sensory neuron and explain synaptic transmission (vesicles, neurotransmitters, receptors, reuptake). The roles of Broca's area (speech production) and Wernicke's area (language comprehension) are also frequently tested, often using case studies like Tan or patient KF.
你必须能够标出运动神经元、中间神经元或感觉神经元的结构，并解释突触传递（囊泡、神经递质、受体、再摄取）。Broca区（言语产生）和 Wernicke区（语言理解）的作用也常被考查，往往通过案例研究如 Tan 或患者 KF 来出题。
Common Mistake 1: Swapping the functions of Broca's and Wernicke's areas. A memorable slip is stating that 'Broca's area is responsible for understanding language'. Actually, damage to Broca's area leads to non-fluent aphasia where speech production is impaired but comprehension is relatively preserved. Wernicke's area damage leads to fluent but meaningless speech.
常见错误1：互换 Broca 区与 Wernicke 区的功能。一个常见的错误是声称“Broca区负责理解语言”。实际上，Broca区受损导致非流利性失语症，言语产生受损但理解相对保留。Wernicke区受损导致言语流利但缺乏意义。
Common Mistake 2: Confusing neurotransmitters with hormones. Neurotransmitters like serotonin and dopamine work across the synapse, while hormones like adrenaline are secreted into the bloodstream. In an essay about biological explanations of depression, students sometimes incorrectly describe serotonin as a hormone travelling through blood.
常见错误2：混淆神经递质与激素。血清素、多巴胺等神经递质在突触间传递，而肾上腺素等激素则分泌到血液中。在关于抑郁症的生物学解释中，学生有时错误地把血清素描述为通过血液流动的激素。
7. Individual Differences: Personality and Measuring Traits | 个体差异：人格与特质测量
Eysenck's PEN model (Psychoticism, Extraversion, Neuroticism) and Freud's structure of personality (id, ego, superego) are classic theories. Questions may ask you to evaluate personality scales such as the EPQ, focusing on reliability, validity and cultural bias.
Eysenck 的 PEN 模型（精神质、外倾性、神经质）与 Freud 的人格结构（本我、自我、超我）是经典理论。考题可能要求你评价艾森克人格问卷等量表，侧重信度、效度和文化偏见。
Common Mistake 1: Treating personality traits as fixed and unchangeable. The interactionist approach suggests behaviour is influenced by both personality and situation. Saying 'an extravert will always be outgoing' ignores situational constraints. This is a key evaluation point.
常见错误1：将人格特质视为固定不变的。交互作用取向认为行为受人格和情境共同影响。声称“外倾者永远外向”忽略了情境因素。这是一个关键的评析点。
Common Mistake 2: Equating reliability with validity. A test can be reliable (producing consistent results) without being valid (measuring what it claims to measure). For example, a personality questionnaire might consistently give the same score but not actually measure extraversion due to social desirability bias.
常见错误2：把信度等同于效度。一个测验可以具有高信度（结果一致），但效度低（未能测量其声称测量的内容）。例如，一份人格问卷可能总能给出同样的分数，但由于社会赞许性偏差，它并未真正测量外倾性。
8. Mental Health: Defining Abnormality and Explanations of Disorders | 心理健康：异常行为的定义与障碍解释
The four definitions of abnormality (statistical infrequency, deviation from social norms, failure to function adequately, deviation from ideal mental health) must be compared and contrasted. The Rosenhan (1973) 'Being Sane in Insane Places' study is a staple for evaluating the reliability of diagnosis. Biological and psychological treatments for depression or phobias (CBT, SSRIs) are examined as applications.
异常的四种定义（统计稀有、偏离社会规范、无法充分正常生活、偏离理想心理健康）需要比较和分析。Rosenhan (1973) 的“当正常人在不正常的地方”研究是评估诊断信度的核心案例。抑郁症或恐惧症的生物学治疗与心理治疗（CBT, SSRIs）作为应用题进行考查。
Common Mistake 1: Assuming one definition works for all cultures. Behaviour that is statistically rare in one culture may be common in another. The deviation from social norms definition is culturally relative, and students lose marks when they overlook this in evaluation.
常见错误1：假定一种定义适用于所有文化。在一种文化中统计上罕见的行为，可能在另一种文化中普遍存在。偏离社会规范的定义具有文化相对性，学生常在评析中忽略这一点而失分。
Common Mistake 2: Claiming that low serotonin causes depression without nuance. The link between serotonin and depression is correlational. A common exam error is to state a direct causal relationship, ignoring that low serotonin could be a consequence rather than a cause, or that other neurotransmitters are also involved.
常见错误2：不加限定地声称低血清素导致抑郁症。血清素与抑郁之间的关系是相关性的。一个常见的考试错误是声称直接的因果关系，忽视了低血清素可能是结果而非原因，也忽略了其他神经递质的参与。
9. Research Evaluation: Reliability, Validity and Sampling | 研究评价：信度、效度与抽样
When you are asked to evaluate a study, you must address internal validity (does the study test what it intends to?), external/ecological validity (can results generalise to real life?) and reliability (are the findings consistent?). Sampling methods—random, stratified, opportunity and volunteer—carry their own strengths and biases.
当题目要求评价一项研究时，你必须涉及内部效度（研究是否测试了它想测的？）、外部/生态效度（结果能否推广到现实生活？）和信度（研究结果是否一致？）。抽样方法——随机、分层、机会与志愿者——各有利弊与偏差。
Common Mistake 1: Using reliability to answer a question about validity. If a question asks whether a study measures what it claims, describing high test-retest reliability does not answer the question. Validity and reliability are distinct concepts and must be addressed separately.
常见错误1：用信度回答关于效度的问题。如果题目问一项研究是否测量了它声称要测量的东西，描述重测信度高并不能回答问题。效度和信度是不同的概念，必须分别阐述。
Common Mistake 2: Thinking a large sample automatically means representative. An opportunity sample of 200 people from a shopping centre may still be biased towards certain demographics and not representative of the whole population. Sampling technique matters more than raw sample size.
常见错误2：认为大样本就自动具有代表性。来自购物中心的 200 人机会样本可能仍偏向某些人群，无法代表总体。抽样技术比单纯的样本量更重要。
10. Exam Technique: Command Words and Applied Analysis | 考试技巧：指令词与应用分析
CAIE psychology papers use specific command words. 'Identify' requires a brief, accurate answer. 'Describe' demands detail—often of a procedure or theory. 'Explain' requires reasons or mechanisms. 'Evaluate' calls for strengths, weaknesses and a balanced conclusion. Misjudging these is a top source of lost marks.
CAIE 心理学试卷使用特定的指令词。“Identify”要求简短准确的回答。“Describe”需要详细说明——通常是程序或理论。“Explain”要求给出原因或机制。“Evaluate”则要求陈述优缺点并给出平衡的结论。对这些指令词的误判是失分的主要来源之一。
Common Mistake 1: Describing instead of evaluating. If a 6-mark question says 'Evaluate the multi-store model', simply listing the components of the model will only earn low marks. You must include supporting evidence (e.g., the primacy and recency effect) and criticisms (e.g., the model is oversimplified, working memory offers a better account).
常见错误1：以描述代替评析。如果一道 6 分题说“评析多存储器模型”，仅仅列出模型的各部分只能得低分。你必须提供支持性证据（例如首因效应和近因效应）和批评（例如模型过于简化，工作记忆能提供更好的解释）。
Common Mistake 2: Not linking an application back to the study. When a scenario-based question asks you to apply a concept, you must explicitly link your answer to details in the stem. For example, if asked how a teacher could use chunking, state: 'The teacher could present the 10-digit code in three groups, which reduces the load on STM capacity, as shown by Miller.' A vague answer without the study reference loses marks.
常见错误2：没有将应用与所学研究相联系。当基于情境的题目要求
