本文拆解了剑桥 IGCSE 心理学（9-1）Year 10 阶段最高频的考查课题，并精准定位了那些容易丢分的常见错误。通过将清晰的学科讲解与针对性的错误分析结合起来，这份指南旨在帮助你把复习转化为真正的考试表现。
1. Biological Psychology: Synaptic Transmission and Brain Localisation | 生物心理学：突触传递与大脑功能定位
Neurons communicate across a tiny gap called the synapse. When an electrical impulse reaches the presynaptic terminal, vesicles release neurotransmitters into the synaptic cleft. These chemical messengers bind to receptor sites on the postsynaptic neuron, triggering either excitation or inhibition. Reuptake then removes excess neurotransmitters to end the signal.
神经元通过一个叫做突触的微小间隙进行交流。当电信号到达突触前末梢时，囊泡会将神经递质释放到突触间隙中。这些化学信使与突触后神经元上的受体位点结合，引发兴奋或抑制。随后，再摄取过程会清除多余的神经递质以终止信号。
Examination questions often ask about the function of the frontal lobe and occipital lobe. The frontal lobe governs decision-making, impulse control and voluntary movement; the occipital lobe processes visual information. The temporal lobe handles auditory input and, in the left hemisphere, language comprehension (Wernicke's area). Broca's area in the frontal lobe is responsible for speech production.
考试题目经常会问到额叶与枕叶的功能。额叶主管决策、冲动控制和随意运动；枕叶负责处理视觉信息。颞叶处理听觉输入，并且在左半球负责语言理解（韦尼克区）。位于额叶的布洛卡区则负责语言产出。
One very common error is writing that neurotransmitters 'jump' across the synapse without mentioning receptors. Others mix up the roles of Broca's and Wernicke's areas. Always link each brain region to its specific function and avoid vague terms like 'the brain controls everything'.
一个非常常见的错误是写神经递质“跳过”突触而不提及受体。还有人会把布洛卡区和韦尼克区的功能混淆。始终将每个脑区与其具体功能相联系，并避免使用“大脑控制一切”之类的模糊表述。
2. Memory: The Atkinson-Shiffrin Multi-Store Model | 记忆：阿特金森-希弗林多存储模型
The multi-store model proposes three separate stores: sensory memory, short-term memory (STM) and long-term memory (LTM). Information enters sensory memory and, if attended to, passes into STM. Rehearsal then transfers it to LTM. Each store differs in duration, capacity and encoding.
多存储模型提出存在三个独立的存储库：感觉记忆、短时记忆（STM）和长时记忆（LTM）。信息先进入感觉记忆，若受到注意则转入 STM。复述进而将其转入 LTM。每个存储库在持续时间、容量和编码方式上各有不同。
about 18-30 seconds, and encodes mainly acoustically. LTM has potentially unlimited capacity and duration, and encodes primarily semantically.
感觉记忆的容量非常大但持续时间不到一秒。STM 可容纳约 7±2 个项目，保持 18-30 秒左右，并主要以听觉方式编码。LTM 的容量和持续时间潜在地无限，且主要以语义方式编码。
Students frequently lose marks by stating that STM encodes 'by sound' without using the technical term 'acoustic encoding'. Another error is claiming that information enters LTM without rehearsal, or confusing the capacity of STM with that of sensory memory. Make sure you can describe the model in terms of the three distinct stores and the processes of attention and rehearsal.
学生经常会因为只写 STM “通过声音”编码而未使用专业术语“听觉编码”而丢分。另一个错误是声称信息无需复述就能进入 LTM，或者混淆 STM 与感觉记忆的容量。务必能用三个独立存储库以及注意和复述过程来描述该模型。
3. Forgetting: Interference Theory and Retrieval Failure | 遗忘：干扰理论与提取失败
Two major explanations for forgetting are tested regularly: interference and retrieval failure. Proactive interference occurs when old learning disrupts recall of new information; retroactive interference is when new learning disrupts recall of old information. Both effects become stronger when the material is similar.
遗忘的两种主要解释经常被考查：干扰和提取失败。前摄干扰是指旧的学习干扰对新信息的回忆；倒摄干扰是指新的学习干扰对旧信息的回忆。当材料相似时，这两种效应都会变得更强。
Retrieval failure states that information is available but not accessible without appropriate cues. Context-dependent forgetting shows that recall is better when the learning environment is reinstated; state-dependent forgetting refers to the match between internal state (e.g. mood) at learning and at recall.
提取失败理论认为，信息是存在的，但若没有适当的线索便无法提取。情境依赖遗忘表明，当学习环境被恢复时回忆会更好；状态依赖遗忘则指学习时与回忆时的内部状态（如情绪）相匹配。
A common exam mistake is defining interference as simply 'forgetting because of time' ve interference. Remember: proactive = forward-acting (old harms new), retroactive = backward-acting (new harms old).
考试中常见的错误是将干扰简单定义为“因时间而遗忘”。干扰是关于其他记忆的破坏效应，而非痕迹消退。此外，学生经常把前摄干扰和倒摄干扰的方向弄反。记住：前摄 = 前行作用（旧伤害新），倒摄 = 逆行作用（新伤害旧）。
4. Social Influence: Asch’s Conformity Experiment and Variables | 社会影响：阿希从众实验与变量
Asch (1951) demonstrated conformity by asking participants to match line lengths aloud after confederates gave unanimous wrong answers. About 37% of responses were conforming errors, and 75% of participants conformed at least once. The real task was clear, showing that people conform even to an obviously incorrect majority.
阿希（1951）通过让参与者在多数同盟者一致给出错误答案后大声匹配线段长度，证明了从众行为。约有37%的反应是从众错误，75%的参与者在至少一次实验中从众。真正的任务很清晰，这表明人们即便面对明显错误的大多数也会从众。
Key variables affecting conformity include group size (conformity increases up to about three confederates, then levels off), unanimity (a dissenting partner drastically reduces conformity), and task difficulty (harder tasks increase conformity because people doubt their own judgement).
影响从众的关键变量包括：群体大小（从众增加到约三个同盟者后趋于平缓）、一致性（有一个异议者会大幅降低从众）以及任务难度（更难的任务会增加从众，因为人们怀疑自己的判断）。
Many candidates confuse conformity with obedience. Conformity involves yielding to group pressure without a direct order, whereas obedience follows a direct command from an authority figure. In describing Asch, avoid saying participants 'obeyed' the confederates. Use the term 'conformed' correctly.
许多考生会混淆从众与服从。从众是在没有直接指令的情况下屈从于群体压力，而服从是遵循权威人物的直接命令。在描述阿希实验时，避免说参与者“服从”了同盟者。要正确使用“从众”一词。
5. Obedience to Authority: Milgram’s Study and Ethics | 服从权威：米尔格拉姆的研究与伦理
Milgram (1963) recruited participants for a 'learning experiment' in which they were instructed to give increasing electric shocks to a confederate learner. No real shocks were given, but participants believed they were. 65% administered the maximum 450-volt shock. The study revealed the powerful influence of an authority figure in a legitimate setting.
米尔格拉姆（1963）为一项“学习实验”招募了参与者，并指示他们对一名同盟者“学习者”施加逐渐增强的电击。实际上并没有真正的电击，但参与者信以为真。65%的参与者给出了最高450伏的电击。该研究揭示了在合法环境中权威人物的强大影响力。
Several situational factors affect obedience: proximity of the authority figure, proximity of the victim, and the prestige of the setting. When the experimenter gave orders by telephone, obedience dropped to 20.5%. When two confederate teachers rebelled, obedience fell to 10%.
几个情境因素会影响服从：权威人物的接近程度、受害者的接近程度以及情境的声望。当实验者通过电话下命令时，服从率降至20.5%。当有两名同盟者教师反抗时，服从率降至10%。
Ethical criticisms of Milgram are a high-frequency exam topic. Candidates often list merely 'it was unethical' without explanation. You must specify: deception (participants believed they were shocking someone), lack of informed consent, and the right to withdraw being compromised. Always link each ethical issue to specific evidence from the procedure.
针对米尔格拉姆实验的伦理批评是高频考点。考生往往只列出“这不道德”而无解释。你必须明确指出：欺骗（参与者相信自己在电击他人）、缺乏知情同意、退出权受到损害。始终将每个伦理问题与程序中的具体证据联系起来。
6. Attachment: Ainsworth’s Strange Situation and Types | 依恋：安斯沃斯陌生情境与类型
The Strange Situation (Ainsworth et al., 1978) is a controlled observation used to assess attachment quality in infants aged 12–18 months. It involves seven episodes of separations and reunions with the caregiver and a stranger. The infant’s behaviour during reunion is key to classifying attachment type.
陌生情境（安斯沃斯等人，1978年）是一项用于评估12-18个月婴儿依恋质量的受控观察。它包含七幕与照看者和陌生人分离与重聚的情节。重聚时婴儿的行为是判断依恋类型的关键。
Three main attachment types are identified: Type B (secure) – infant uses caregiver as a secure base, shows distress on separation but is quickly comforted on reunion; Type A (insecure-avoidant) – infant ignores caregiver, treats caregiver and stranger similarly; Type C (insecure-resistant) – infant clings to caregiver, resists comfort on reunion and may show anger.
识别出三种主要依恋类型：B型（安全型）——婴儿将照看者作为安全基地，分离时痛苦但重聚时很快得到安慰；A型（不安全-回避型）——婴儿忽视照看者，对待照看者与陌生人相似；C型（不安全-反抗型）——婴儿缠着照看者，重聚时抗拒安慰并可能表现出愤怒。
A typical error is writing that Type A infants are 'shy' or 'independent', which are personality labels, not attachment behaviours. Examination questions require you to describe observable behaviours, not make inferences. Also, many students confuse the high anxiety in Type C with the low anxiety in Type A, so focus on reunion responses.
典型的错误是把A型婴儿写成“害羞”或“独立”，这是对人格的标签而非依恋行为。考试题目要求你描述可观察的行为，而非进行推断。此外，许多学生会把C型的高焦虑与A型的低焦虑混淆，因此要聚焦于重聚反应。
7. Learning Theories: Generalisation and Discrimination in Classical Conditioning | 学习理论：经典条件作用中的泛化与辨别
In Pavlov's classical conditioning, a neutral stimulus becomes a conditioned stimulus (CS) that elicits a conditioned response (CR) after being paired with an unconditioned stimulus (UCS). Once conditioning occurs, the CR may appear in response to stimuli similar to the CS – this is called generalisation.
在巴甫洛夫的经典条件作用中，一个中性刺激在与非条件刺激（UCS）配对后，变成能引发条件反应（CR）的条件刺激（CS）。一旦条件作用形成，CR 可能会对与 CS 相似的刺激出现——这叫做泛化。
Discrimination is the opposite process: the organism learns to distinguish between the original CS and other, similar stimuli that are not followed by the UCS. For example, a dog salivates to a 1000 Hz tone but not to an 800 Hz tone if only the 1000 Hz tone has been paired with food.
辨别是相反的过程：有机体学会区分原始的 CS 与其他类似但不跟随 UCS 的刺激。例如，一只狗对 1000 Hz 的音调分泌唾液，但不对 800 Hz 的音调分泌，如果只有 1000 Hz 的音调曾与食物配对。
Students often mislabel generalisation as 'spontaneous recovery' or 'extinction'. Spontaneous recovery is the reappearance of a CR after a rest period, while extinction is the weakening of the CR when the CS is presented without the UCS. Learn to differentiate these four processes because exam questions frequently swap them in scenario-based items.
学生经常把泛化错贴成“自发恢复”或“消退”。自发恢复是休息一段时间后 CR 的再次出现，而消退是当 CS 单独呈现不伴随 UCS 时 CR 的减弱。要学会区分这四个过程，因为考试经常在情境题中互换它们。
8. Research Methods: Variables, Hypotheses and Experimental Designs | 研究方法：变量、假设与实验设计
Every experiment manipulates an independent variable (IV) and measures a dependent variable (DV). Extraneous variables (EVs) must be controlled to prevent them from becoming confounding variables that ruin internal validity. A clearly operationalised hypothesis – 'if the IV is changed, then the DV will change because…' – is essential.
每一个实验都会操纵一个自变量（IV）并测量一个因变量（DV）。额外变量（EV）必须得到控制，以防它们成为破坏内部效度的混淆变量。清晰操作化的假设——“如果改变了 IV，那么 DV 将会改变因为……”——至关重要。
Three experimental designs are tested: independent groups (different participants in each condition), repeated measures (same participants in all conditions) and matched pairs (participants are matched on a relevant trait). Each design has distinct strengths: independent groups avoid order effects but need more participants; repeated measures control participant variables but risk order effects; matched pairs reduce participant variables but can be time-consuming.
三种实验设计会出现在试题中：独立组设计（每个条件采用不同参与者）、重复测量（所有条件采用同一批参与者）和配对组（根据相关特征匹配参与者）。每种设计都有独特的优势：独立组避免了顺序效应但需要更多参与者；重复测量控制了参与者变量但有顺序效应风险；配对组减少了参与者变量但可能很耗时。
Confusing an IV with a DV is a surprisingly frequent error. The IV is what the researcher changes or compares; the DV is what is measured. Another common slip is writing a one-tailed hypothesis as 'there will be a difference' instead of specifying the direction, or failing to operationalise – for instance, writing 'memory will be better' without saying how memory is measured.
混淆 IV 和 DV 是出奇常见的错误。IV 是研究者改变或比较的东西；DV 是被测量的东西。另一个常见疏漏是在写单尾假设时只写“会有差异”而不指明方向，或者没有进行操作化——比如写“记忆力会更好”而不说明如何测量记忆。
9. Evaluating Research: Reliability, Validity and Ecological Validity | 研究评价：信度、效度与生态效度
Reliability refers to consistency. If a study is repeated and similar results are obtained, it has external reliability. Internal reliability means that the procedures and measurements within a single study are consistent. Validity asks whether a study truly measures what it claims to measure.
信度指的是可重复性。如果一项研究可以被重复得出相似结果，它就具有外部信度。内部信度意味着单个研究内的程序和测量是统一的。效度则问的是研究是否真正测量了它所声称要测量的东西。
Ecological validity is the extent to which findings generalise to real-life settings. A laboratory study like Milgram's is often criticised for low ecological validity because the artificial task may not represent how people respond to authority outside the lab. However, some researchers argue that just because a setting is artificial does not automatically make the results inapplicable.
生态效度是指研究发现能推广至现实生活情境的程度。像米尔格拉姆实验这样的实验室研究常因生态效度低而受批评，因为人工化的任务可能无法代表人们在实验室之外对权威的反应。不过，一些研究者认为，仅仅因为情境是人为设置的，并不能自动意味着结果就不适用。
Weak evaluation statements such as 'it was a lab study so it's not valid' lose marks. You must explain why that feature threatens validity and, if possible, contrast with a strength. For example: 'The high control over EVs strengthens internal validity, but the artificial tasks like pressing shock buttons may lower ecological validity.' Show a balanced judgement.
诸如“这是实验室研究所以无效”之类的无力评价会丢分。你必须解释为什么那个特点会威胁效度，并在可能的情况下与某个优点对比。例如：“对额外变量的高度控制加强了内部效度，但按电击按钮之类人工化的任务可能降低生态效度。”要展现出平衡的判断。
10. Common Exam Errors and How to Avoid Them | 常见考试错误及避坑指南
Many candidates lose marks by simply describing a study without linking back to the question. If asked to 'discuss' or 'evaluate', you must provide strengths and weaknesses, not just a summary of procedure. Use the PEEL structure: Point, Evidence, Explanation, Link.
许多考生仅描述了研究却没有回扣题目，因而丢分。如果题目要求“讨论”或“评价”，你必须给出优点与缺点，而不仅仅是对程序的概述。请使用 PEEL 结构：论点、证据、解释、链接。
Another frequent mistake is using terms like 'proves' or 'the experiment showed that…' Psychology research does not prove; it supports, suggests or indicates. Similarly, causal language should be avoided unless the study is an experiment with high control.
另一个常见错误是使用“证明”或“该实验显示了……”之类的词。心理学研究不提供证明；它支持、表明或指示。同样，除非是高控制的实验，否则应避免因果语言。
A table of high-frequency substitution errors is shown below. These mixing-ups appear in many past papers and cost easy marks.
下表显示了高频率的术语混淆错误。这些混淆在众多历年考卷中出现，导致轻易失分。
