1. The Multi-Store Model of Memory | 记忆的多存储模型
The multi-store model, proposed by Atkinson and Shiffrin, divides memory into three separate stores: sensory memory, short-term memory (STM), and long-term memory (LTM). Information flows between them through attention and rehearsal.
多存储模型由 Atkinson 和 Shiffrin 提出，将记忆分为三个独立的存储库：感觉记忆、短期记忆（STM）和长期记忆（LTM）。信息通过注意和复述在它们之间流动。
Sensory memory holds incoming information for a fraction of a second. If you pay attention to it, the information passes into STM. Without attention, it decays rapidly.
感觉记忆将传入的信息保持几分之一秒。如果你注意到它，信息便进入 STM。若无注意，信息会迅速消退。
Short-term memory has a limited capacity of 7±2 items and a duration of about 18–30 seconds. Rehearsal keeps information in STM and helps transfer it to LTM.
短期记忆的容量有限，为 7±2 个组块，持续时间约 18–30 秒。复述可将信息保持在 STM 中，并帮助其转入 LTM。
Long-term memory has potentially unlimited capacity and can store information for a lifetime. It is coded mainly by meaning (semantic coding).
长期记忆的容量可能无限，可存储信息长达一生。其编码主要按意义进行（语义编码）。
2. Explanations of Forgetting | 遗忘的解释
Two main explanations of forgetting are decay and interference. Decay theory suggests that memories fade over time if they are not used, especially in STM.
遗忘的两个主要解释是消退和干扰。消退理论认为，若不使用，记忆会随时间的推移而淡化，这在 STM 中尤为明显。
Interference occurs when other memories disrupt the recall of the target memory. Proactive interference is when old learning hinders new learning, while retroactive interference is when new learning disrupts old memories.
干扰指的是其他记忆干扰目标记忆的提取。前摄干扰是指旧的学习阻碍新学习，倒摄干扰则是新的学习干扰旧记忆。
Exam questions often ask you to identify whether a scenario describes proactive or retroactive interference. A common mistake is to mix up the direction of interference.
考题常要求你判断一个场景描述的是前摄干扰还是倒摄干扰。常见错误是混淆干扰的方向。
3. Conformity and Why We Follow the Crowd | 从众及我们为何随大流
Conformity is a type of social influence where an individual changes their behaviour or beliefs to fit in with a group. This can happen due to normative social influence (desire to be liked) or informational social influence (desire to be right).
从众是一种社会影响，个体改变其行为或信念以融入群体。这可能源于规范社会影响（希望被喜欢）或信息社会影响（希望正确）。
Asch’s line study showed that even when the answer was obvious, many participants conformed to the group’s wrong answer. This illustrates the power of majority influence.
Asch 的线段研究显示，即使答案明显，许多参与者也会从众于群体的错误答案。这说明了多数人影响力的强大。
Students often wrongly assume that conformity always means private acceptance. In reality, compliance can occur without genuine belief change.
学生常错误地认为从众总意味着私下接纳。实际上，顺从可能发生，而内在信念并未改变。
4. Obedience to Authority | 服从权威
Obedience involves following a direct order from an authority figure. Milgram’s electric shock experiment revealed that ordinary people can commit harmful acts when instructed by a legitimate authority.
服从涉及听从权威人物的直接命令。Milgram 的电击实验揭示，普通人在合法权威的指令下可能做出有害行为。
Factors affecting obedience include proximity of the authority figure, prestige of the setting, and the presence of disobedient peers. A common pitfall is confusing obedience with conformity.
影响服从的因素包括权威人物的接近程度、环境声望以及是否存在不服从的同辈。常见误区是把服从与从众混为一谈。
Remember: conformity is about peer pressure, obedience is about direct commands from someone in power.
记住：从众关乎同伴压力，服从则关乎掌权者的直接命令。
5. Experimental Design: Independent Groups & Repeated Measures | 实验设计：独立组与重复测量
In independent groups design, different participants are allocated to the control and experimental conditions. This avoids order effects but requires more participants and may suffer from individual differences.
在独立组设计中，不同的参与者被分配到控制组和实验组。这避免了顺序效应，但需要更多参与者，并可能受个体差异影响。
In repeated measures design, the same participants take part in all conditions. This controls for participant variables but can lead to order effects such as practice or fatigue.
在重复测量设计中，同一批参与者参加所有条件。这控制了参与者变量，但可能导致练习或疲劳等顺序效应。
When answering exam questions, always identify the design used and explain one strength and one limitation clearly.
回答考题时，务必指出所使用的设计，并清晰地解释一个优点和一个局限性。
6. Ethical Issues in Psychological Research | 心理学研究中的伦理问题
Ethical guidelines protect participants from harm. Key principles include informed consent, right to withdraw, confidentiality, protection from harm, and debriefing.
伦理准则保护参与者免受伤害。关键原则包括知情同意、退出权、保密、免受伤害以及事后解释。
Milgram’s study raised serious ethical concerns because participants were deceived and experienced extreme stress. Modern studies must be approved by an ethics committee.
Milgram 的研究引发了严重的伦理关切，因为参与者被欺骗并承受了极度压力。现代研究必须获得伦理委员会的批准。
A typical mistake is to describe an ethical issue without linking it to at least one specific principle. Always name the principle explicitly, e.g., ‘deception violated informed consent’.
一个典型错误是描述伦理问题却不关联至少一项具体原则。务必明确说出原则名称，如“欺骗违反了知情同意”。
7. Sleep and Dreaming: Freud’s Theory | 睡眠与做梦：弗洛伊德的理论
Sigmund Freud proposed that dreams are the ‘royal road to the unconscious’. He believed dreams allow us to express unconscious wishes and desires in a disguised, symbolic way.
西格蒙德·弗洛伊德提出，梦是“通往潜意识的捷径”。他认为梦使我们能够以伪装、象征的方式表达潜意识的愿望与欲望。
According to Freud, a dream has two levels of content: the manifest content (the story you remember) and the latent content (the hidden meaning). Dreamwork transforms the latent content into the manifest content.
根据弗洛伊德，梦具有两个层次的内容：显性内容（你记得的故事）和隐性内容（隐藏的含义）。梦的工作将隐性内容转化为显性内容。
Students sometimes confuse Freud’s theory with biological theories of dreaming. Freud focuses on psychological meaning, not on random brain activation.
学生有时会混淆弗洛伊德的理论与关于梦的生物学理论。弗洛伊德关注心理意义，而非随机脑激活。
8. Piaget’s Stages of Cognitive Development | 皮亚杰的认知发展阶段
Jean Piaget suggested that children go through four stages of cognitive development: sensorimotor, pre-operational, concrete operational, and formal operational. Each stage represents a different way of thinking.
让·皮亚杰认为儿童经历四个认知发展阶段：感知运动阶段、前运算阶段、具体运算阶段和形式运算阶段。每个阶段代表不同的思维方式。
In the pre-operational stage (ages 2–7), children are egocentric and struggle with conservation tasks. They may believe that spreading out coins means there are more coins, even when the number hasn’t changed.
在前运算阶段（2–7 岁），儿童以自我为中心，并在守恒任务上存在困难。他们可能认为硬币摊开后数量变多了，即使数量并未改变。
A classic exam error is to claim that pre-operational children can perform logical operations. Only in the concrete operational stage do they begin to think logically about concrete objects.
经典考试错误是声称前运算阶段的儿童能进行逻辑运算。只有到了具体运算阶段，他们才开始对具体事物进行逻辑思考。
9. Common Mistake: Confusing IV and DV | 常见错误：混淆自变量和因变量
The independent variable (IV) is the factor the researcher manipulates or changes. The dependent variable (DV) is what is measured or observed. In an experiment on the effect of caffeine on memory, the IV is caffeine intake, and the DV is memory performance.
自变量（IV）是研究者操纵或改变的因素。因变量（DV）是被测量或观察的东西。在一项关于咖啡因对记忆影响的实验中，IV 是咖啡因摄入量，DV 是记忆表现。
Many students identify the IV as the result. Remember: the IV is the potential cause, the DV is the effect. A helpful mnemonic is that the DV depends on the IV.
许多学生将 IV 误认为是结果。记住：IV 是潜在原因，DV 是结果。一个有用的记忆方法是 DV 依赖于 IV。
10. Misinterpreting Correlation as Causation | 将相关误解为因果
A correlation shows a relationship between two variables, but it does not prove that one variable causes the other. A third variable may explain the association.
相关展示两个变量之间的关系，但它并不证明一个变量导致了另一个。可能存在第三个变量解释这一关联。
For example, a positive correlation between ice cream sales and drowning rates does not mean ice cream causes drowning. The third variable is likely hot weather, which increases both.
例如，冰淇淋销量与溺水率之间的正相关并不意味着冰淇淋导致溺水。第三个变量很可能是炎热天气，它同时增加了二者。
In exams, always use the phrase ‘correlation does not imply causation’ when interpreting correlational data.
考试中解读相关数据时，务必使用“相关不意味着因果”这一说法。
11. Calculation Errors: Mean, Median, Mode, Range | 计算错误：平均数、中位数、众数、范围
The mean is calculated by adding all values and dividing by the number of values. The median is the middle score when data are in order. The mode is the most frequent score. The range is the difference between the highest and lowest scores.
平均数通过将所有数值相加再除以数值个数得出。中位数是将数据排序后位于中间的分数。众数是出现最频繁的分数。范围是最高分与最低分之差。
Mean = (sum of scores) ÷ number of scores
平均数 = (总分之和) ÷ 分数个数
Common slip-ups include using the wrong divisor for the mean, forgetting to put data in order for the median, and giving the mode as a count instead of the actual value.
常见的疏忽包括：在计算平均数时用错除数、求中位数时忘记先排序，以及把众数报成次数而非具体数值。
12. Exam Technique: How to Structure a 6-Mark Answer | 考试技巧：如何构建6分答案
For extended response questions, use a clear structure: first state your point, then provide evidence or an example, and finally explain why it matters. Link back to the question throughout.
面对扩展型题目，使用清晰的结构：先陈述观点，接着提供证据或例子，最后解释其重要性。始终回应题目要求。
If asked to evaluate a study, describe one strength and one limitation. Always use psychological terminology, e.g., ‘high ecological validity’ or ‘lack of population validity’.
若要求评价一项研究，需描述一个优势和一个局限性。务必使用心理学专业术语，如“生态效度高”或“缺乏人口效度”。
Avoid simple description. Show analysis by discussing implications or suggesting how a limitation could be overcome.
避免简单描述。通过讨论影响或提出如何克服局限性来展现分析能力。
