1. Memory: Multi-Store Model | 记忆：多贮存模型

The multi-store model (Atkinson & Shiffrin) is a cornerstone of the memory unit. You must know the capacity, duration, and coding of sensory register, short-term memory (STM), and long-term memory (LTM). A typical exam question asks you to identify which store holds information for around 7±2 chunks or how information passes from STM to LTM through rehearsal.

多贮存模型（阿特金森和谢夫林）是记忆单元的基础。你必须掌握感觉登记、短期记忆（STM）和长期记忆（LTM）的容量、持续时间和编码方式。典型的考题会要求你判断哪个记忆贮存能容纳约 7±2 个组块，或是信息如何通过复述从 STM 转入 LTM。

A common error is confusing capacity with duration — for example, stating that STM has a large capacity but lasts only a few seconds. Another mistake is believing that rehearsal is the only route into LTM; elaborative and meaningful processing also play a role, and mentioning them can earn higher marks.

一个常见错误是混淆容量与持续时间——例如，认为 STM 容量很大但只持续几秒。另一个错误是认为复述是进入 LTM 的唯一途径；精细加工与意义加工同样重要，提及它们可以帮你赢得更高分数。

• High-frequency trap: mislabelling the sensory register as having a duration of seconds rather than milliseconds.
• 高频陷阱：将感觉登记的错误持续时间为秒，而非毫秒级。

2. Memory: Forgetting and Interference | 记忆：遗忘与干扰

Interference theory explains forgetting through proactive interference (old learning disrupts new) and retroactive interference (new learning disrupts old). Examiners love real-life application questions, e.g. ‘Why might a student confuse their new locker combination with the old one?’

干扰理论通过前摄干扰（旧知识干扰新知识）和倒摄干扰（新知识干扰旧知识）来解释遗忘。考官喜欢出应用类题目，例如“为什么学生可能会把新储物柜密码跟旧密码搞混？”

The most frequent mistake is reversing the two types. To avoid this, remember: proactive = old affects new (pro- means forward, so acting forward to block new); retroactive = new affects old (retro- means backward, acting backward to cloud old). Some students also forget to link interference to the similarity of materials — interference is stronger when the two sets of information are alike.

最常见的错误是把两类干扰弄反。为避免混淆，请记住：前摄干扰（proactive）是旧影响新（pro- 意为向前，向前阻碍新信息）；倒摄干扰（retroactive）是新影响旧（retro- 意为向后，向后遮盖旧信息）。一些学生还忘记把干扰与材料相似性联系起来——两套信息越相似，干扰越强。

• High-frequency trap: using cue-dependent forgetting as an example of interference.
• 高频陷阱：把线索依赖遗忘当作干扰的例子。

3. Social Influence: Conformity and Asch | 社会影响：从众与阿希实验

Asch’s line study demonstrates normative social influence (desire to fit in) and informational social influence (desire to be right). You must recall the key findings: about 75% of participants conformed at least once, and conformity dropped when there was an ally or when responses were written privately.

阿希的线段实验展示出规范性社会影响（渴望融入）和信息性社会影响（渴望正确）。你必须记住关键发现：大约 75% 的参与者至少从众一次，当有一个同盟者或私下书写答案时，从众率会下降。

A common error is thinking Asch studied obedience rather than conformity. Another is labelling all conformity as ‘just wanting to fit in’ without distinguishing normative from informational influence. In 6-mark questions, failing to link a factor (e.g. group size, unanimity) to the type of influence loses marks.

一个常见的错误是认为阿希研究的是服从而非从众。另一个是给所有的从众行为都贴上“只想合群”的标签，而不区分规范性与信息性影响。在 6 分题中，未能将某个因素（如群体大小、一致性）与影响类型联系起来，就会失分。

4. Social Influence: Obedience and Milgram | 社会影响：服从与米尔格拉姆实验

Milgram’s electric shock experiment tested obedience to authority. High-frequency exam points include the percentage who gave the maximum 450V shock (65%), the role of proximity, location, and uniform. You must also discuss ethical criticisms, such as deception and lack of protection from harm.

米尔格拉姆的电击实验测试了对权威的服从。高频考点包括施加最高 450V 电压的人数比例（65%），以及接近性、地点、制服的作用。你还必须讨论伦理批评，比如欺骗和缺乏免受伤害的保护。

Misinterpretations often appear: students say ‘people are naturally cruel’ instead of citing situational factors like the experimenter’s prods. Others confuse the terms ‘obedience’ and ‘conformity’ — obedience involves a direct order from an authority figure; conformity does not. Always specify this distinction in answers.

经常出现错误理解：学生说“人天性残忍”，而不引用情境因素，如实验者的催促。还有人混淆“服从”和“从众”——服从涉及权威人物直接下命令，从众则不然。在答案中务必明确这一区别。

5. Development: Piaget’s Stages | 发展：皮亚杰认知发展阶段

Piaget’s four stages of cognitive development — sensorimotor, pre-operational, concrete operational, and formal operational — are regularly tested. You need to know the approximate ages, key achievements (object permanence, egocentrism, conservation, abstract reasoning), and be able to match a child’s behaviour to the correct stage.

皮亚杰的四个认知发展阶段——感知运动、前运算、具体运算和形式运算——经常被考查。你需要知道大致年龄、关键成就（客体永久性、自我中心、守恒、抽象推理），并能将儿童的行为匹配到正确的阶段。

The biggest pitfall is mixing up pre-operational and concrete operational characteristics. Pre-operational children cannot conserve; concrete operational children can conserve but struggle with abstract ideas. Also, do not write that a child ‘learns object permanence’ as a gradual skill — Piaget viewed it as emerging around 8–12 months, but full object permanence is a developmental process. Using precise age ranges prevents confusion.

最大的陷阱是混淆前运算和具体运算的特征。前运算阶段的儿童无法守恒；具体运算阶段儿童能守恒，但难以处理抽象观念。另外，不要把客体永久性写成一项逐步“学会”的技能——皮亚杰认为它约在 8–12 个月出现，但完全形成是一个发展过程。使用精确的年龄范围可以避免混淆。

6. Development: Attachment and Harlow | 发展：依恋与哈洛实验

Harlow’s monkey experiments showed the importance of contact comfort over feeding in forming attachment. High-frequency topics include the wire and cloth mothers, the long-term effects of maternal deprivation, and Ainsworth’s Strange Situation classification (secure, insecure-avoidant, insecure-resistant).

哈洛的猴子实验表明，在形成依恋的过程中，接触安慰比喂养更为重要。高频考点包括铁丝妈妈和绒布妈妈、母爱剥夺的长期影响，以及安斯沃思的陌生情境分类（安全型、不安全－回避型、不安全－反抗型）。

Many students wrongly state that Harlow’s monkeys became attached to the wire mother because it provided food. In reality, they preferred the cloth mother and only went to the wire mother to feed. This underpins the idea that attachment is based on emotional comfort, not just nourishment. When evaluating Harlow, always balance ethical concerns with the study’s significant contribution.

许多学生错误地声称哈洛的猴子依恋铁丝妈妈，因为它提供食物。实际上，它们偏爱绒布妈妈，只在进食时才去找铁丝妈妈。这正说明依恋是基于情感安慰，而不仅仅是喂养。在评价哈洛实验时，务必将伦理关切与其重大贡献进行平衡考量。

7. Research Methods: Variables and Hypotheses | 研究方法：变量与假设

The unit on research methods requires you to identify independent variables (IV), dependent variables (DV), and extraneous variables. You may also be asked to write an appropriate experimental or alternative hypothesis. Operationalising variables — specifying exactly how they will be measured — is crucial for top marks.

研究方法单元要求你识别自变量（IV）、因变量（DV）和额外变量。你可能会被要求撰写一份合适的实验假设或备择假设。操作化变量——确切说明如何测量它们——是取得高分的关键。

Common errors include: stating the IV as ‘memory’ instead of a clearly operationalised condition; failing to indicate the direction in a one-tailed hypothesis; and writing a null hypothesis that still predicts a difference. For example, ‘There will be no significant difference…’ is correct; ‘There will be a difference…’ is not a null. Additionally, mixing up ‘alternative’ and ‘null’ loses easy marks.

常见错误包括：将自变量表述为“记忆”，而非明确操作化的条件；在单尾假设中未能指明方向；以及所写的零假设仍然在预测差异。例如，“将不会出现显著差异……”才是正确的；“将出现差异……”则不是零假设。此外，混淆“备择假设”与“零假设”会丢失易得分。

8. Research Methods: Sampling and Ethics | 研究方法：抽样与伦理

You must know the differences between random, opportunity, volunteer, and stratified sampling, including advantages and limitations. Ethical guidelines — informed consent, deception, right to withdraw, confidentiality, protection from harm — are central to the course and appear in almost every past paper.

你必须了解随机、机会、志愿者和分层抽样之间的差异，包括各自的优势和局限。伦理准则——知情同意、欺骗、退出权、保密和免受伤害——是课程的核心，几乎每次考试都会出现。

One classic mistake is claiming that opportunity sampling is unbiased because it is easy. It is in fact highly biased, as it relies on whoever is available. Another is discussing ethics without fully explaining how to deal with the issue — e.g. simply saying ‘the study was unethical’ gains no credit. You must explain how you would reduce the ethical problem, such as providing a full debrief after deception.

一个经典错误是声称机会抽样没有偏差，因为它很方便。事实上它高度有偏，因为它依赖的是当时恰好能找到的人。另一个错误是在讨论伦理时没有充分解释如何应对问题——例如，仅仅说“这项研究不道德”不得分。你必须说明你会如何减轻伦理问题，比如在欺骗后提供全面的知情解释。

9. Brain and Neuropsychology: Structure and Function | 大脑与神经心理学：结构与功能

You need to localise functions to the frontal lobe (personality, decision-making), temporal lobe (auditory processing, language comprehension via Wernicke’s area), occipital lobe (vision), and parietal lobe (touch, spatial awareness). Broca’s area (speech production) is a frequent target.

你需要将功能定位到额叶（人格、决策）、颞叶（听觉处理、通过韦尼克区实现语言理解）、枕叶（视觉）和顶叶（触觉、空间意识）。布洛卡区（言语产生）是常考目标。

Students frequently confuse Broca’s and Wernicke’s areas. Broca’s is in the frontal lobe and affects speech production; Wernicke’s is in the temporal lobe and affects language comprehension. Damage to Broca’s area causes expressive aphasia (difficulty speaking fluently), while Wernicke’s aphasia leads to fluent but meaningless speech. Using the incorrect example of a patient’s symptoms is a common mistake in application questions.

学生经常混淆布洛卡区和韦尼克区。布洛卡区在额叶，影响言语产生；韦尼克区在颞叶，影响语言理解。布洛卡区受损导致表达性失语症（说话不流利），而韦尼克失语症则导致流利但无意义的言语。在应用题中错误地举例患者症状是一个常见失误。

10. Psychological Problems: Unipolar Depression | 心理问题：单相抑郁症

The specification covers symptoms (low mood, anhedonia, fatigue), the cognitive explanation (Beck’s negative triad of self, world, future), and biological explanations (genetics, serotonin imbalance). You should be able to evaluate the strengths and weaknesses of each explanation.

课程大纲涵盖症状（情绪低落、快感缺失、疲劳）、认知解释（贝克的自我、世界、未来负面三角）以及生物学解释（遗传学、5-羟色胺失衡）。你应能评价每种解释的优缺点。

A recurrent error is offering a one-sided evaluation — for example, only praising the cognitive explanation without noting that it blames the individual and may ignore biological factors. Another is confusing unipolar depression with bipolar depression; the latter involves manic episodes, which are not needed in unipolar questions. Stay precisely within the boundaries of the disorder asked about.

一个反复出现的错误是评价片面——例如，只赞美认知解释，而不指出它责备个体且可能忽略生物学因素。另一个是混淆单相与双相抑郁症；后者包含躁狂发作，在单相问题中不需要提及。务必严格限定在所问障碍的范围内。

---

11. Psychological Problems: Addiction | 心理问题：成瘾

Addiction is often explained through learning theories, especially operant conditioning (positive reinforcement from the ‘high’, negative reinforcement by removing withdrawal symptoms). Tolerance and withdrawal are key concepts. You may be asked to apply these ideas to a novel scenario like smartphone addiction.

成瘾通常通过学习理论来解释，尤其是操作性条件反射（通过“快感”实现正强化，通过消除戒断症状实现负强化）。耐受性与戒断是关键概念。你可能需要将这些观点应用于新情境，例如智能手机成瘾。

Misunderstanding negative reinforcement is extremely common — students say ‘the person takes the drug to avoid punishment’, whereas negative reinforcement actually means removing an unpleasant state, like anxiety or withdrawal. Also, avoid treating tolerance and physical dependence as the same thing: tolerance is needing more of the substance to achieve the same effect; physical dependence is a state where the body requires the drug to function normally. Confusing the two in an explanation will weaken your answer.

误解负强化极为常见——学生说“该人服用药物是为了避免惩罚”，而负强化实际上是指移除不愉快状态，如焦虑或戒断症状。此外，不要将耐受性与躯体依赖等同：耐受性是指需要更多物质才能达到同样效果；躯体依赖则是身体需要该药物才能正常运转。在解释中将两者混淆会削弱你的答案。

12. Exam Technique and Common Mistakes | 考试技巧与常见错误

Many marks are lost not through lack of knowledge, but through poor exam technique. Always check the command word: ‘identify’ requires a single, clear answer; ‘describe’ needs detailed characteristics without evaluation; ‘explain’ demands reasons or mechanisms; ‘evaluate’ requires strengths and weaknesses. Use the PEE structure (Point, Evidence, Explain) for extended answers where appropriate.

许多失分并非因为知识欠缺，而是由于糟糕的考试技巧。务必检查指令词：“identify”要求单一、明确的答案；“describe”需要详细特征，无需评价；“explain”要求给出原因或机制；“evaluate”则要求阐述优点与弱点。在扩展答案中，适时使用 PEE 结构（观点、证据、解释）。

Other common pitfalls: leaving questions blank because they seem hard — even a partial answer can pick up marks; writing illegibly; and spending too long on low-mark questions. Time management is vital. For psychology, always relate your answer back to a named study or theory whenever possible, as generic answers rarely reach the top band. Practising with past papers under timed conditions builds confidence and helps you spot recurring patterns.

其他常见陷阱：因为题目看起来很难就留空——即使部分回答也能得分；字迹潦草；以及在低分值题目上花费太长时间。时间管理至关重要。对于心理学，尽可能将答案联系到指定研究或理论，因为泛泛而谈的答案很少能进入最高等级。在计时条件下练习历年真题，有助于建立信心并帮助发现重复出现的模式。
