1. Memory: Types and Processes | 记忆：类型与过程
The multi-store model of memory is a classic Year 7 topic, distinguishing sensory memory, short-term memory (STM) and long-term memory (LTM). Sensory memory holds information for a fraction of a second before it is either attended to and transferred to STM or lost.
记忆的多重储存模型是 Year 7 的经典课题，它区分了感觉记忆、短时记忆和长时记忆。感觉记忆将信息保持几分之一秒，若未得到注意便消退，若被注意则转入短时记忆。
STM has a limited capacity of 7±2 items (Miller’s ‘magic number’) and a duration of around 18–30 seconds without rehearsal. Encoding in STM is often acoustic, meaning we remember by repeating sounds in our head.
短时记忆的容量有限，为 7±2 个组块（米勒的“魔法数字”），在无复述的情况下持续时间约为 18–30 秒。短时记忆的编码通常是听觉性质的，即我们通过在脑中重复声音来记忆。
LTM, in contrast, has a potentially unlimited capacity and duration, with encoding mainly semantic – based on meaning. Information moves from STM to LTM through elaborative rehearsal, not just simple repetition.
相比之下，长时记忆的容量和持续时间在理论上都是无限的，其编码主要是语义性的——基于意义。信息通过精细复述（而非简单重复）从短时记忆转入长时记忆。
Common mistake: Many students say STM stores information for ‘a few minutes’ or confuse acoustic and semantic encoding. Remember that 18–30 seconds is the typical STM duration unless rehearsal occurs.
常见错误：许多学生声称短时记忆能将信息保持“几分钟”，或混淆听觉编码与语义编码。请记住，若不进行复述，短时记忆的典型时长仅为 18–30 秒。
2. Forgetting and Eyewitness Testimony | 遗忘与目击者证词
Forgetting can occur due to decay, interference, or retrieval failure. Proactive interference happens when old information disrupts recall of new information, while retroactive interference is the reverse.
遗忘可能由痕迹消退、干扰或提取失败导致。前摄干扰指旧信息干扰新信息的回忆，倒摄干扰则相反。
Eyewitness testimony (EWT) is highly relevant for exams. Leading questions, post-event discussion and anxiety can all distort memory. Loftus and Palmer’s classic study showed that the verb used in a question (e.g. ‘smashed’ vs ‘hit’) affected participants’ speed estimates.
目击者证词在考试中相关性极高。引导性问题、事后讨论和焦虑都可能歪曲记忆。洛夫特斯和帕尔默的经典研究表明，问题中使用的动词（如“撞碎”与“碰撞”）会影响参与者对车速的估计。
Students often incorrectly claim that EWT is always unreliable. A better answer acknowledges that it can be unreliable under certain conditions, but is not entirely useless. Use terms like ‘post-event information’ precisely.
学生常错误地断言目击者证词总是不可靠的。更优秀的答案会承认，在特定条件下它可能不可靠，但并非完全无效。请准确使用“事后信息”等术语。
3. Non-verbal Communication | 非言语沟通
Non-verbal communication includes eye contact, facial expressions, body language, personal space and touch. Argyle’s research suggested that eye contact signifies attention and can regulate conversation.
非言语沟通包括眼神接触、面部表情、身体语言、个人空间和触摸。阿盖尔的研究表明，眼神接触表示关注，并能调节对话进程。
Cultural differences are crucial: while a direct gaze may be a sign of honesty in many Western cultures, it can be perceived as disrespectful in some East Asian cultures. Personal space also varies – Hall identified intimate, personal, social and public distances.
文化差异至关重要：在许多西方文化中，直视可能是诚实的标志，但在某些东亚文化中却可能被视为无礼。个人空间也因文化而异——霍尔划分了亲密距离、个人距离、社交距离和公共距离。
A typical error is to overgeneralise findings from one culture to all humans. Always mention that non-verbal rules are influenced by culture, context and individual differences.
一个典型错误是将源自某种文化的发现过度泛化到全人类。务必提及，非言语规则受文化、情境和个体差异的影响。
4. 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. Asch’s line experiment revealed that about 37% of participants conformed to an obviously incorrect majority judgment at least once.
从众指因真实的或想象的群体压力而导致的行为或信念改变。阿希的线段实验揭示，约 37% 的参与者至少一次屈从于明显错误的大多数判断。
Obedience involves following a direct command from an authority figure. Milgram’s famous study showed that 65% of participants were willing to administer what they believed were dangerous electric shocks when instructed by an experimenter.
服从涉及遵从权威人物的直接命令。米尔格拉姆的著名研究显示，65% 的参与者在实验者指令下愿意施加他们相信是危险的电击。
Students often confuse conformity with obedience. Conformity usually lacks an explicit order and stems from peer influence; obedience requires a recognised authority. Never use the two terms interchangeably without clarifying the difference.
学生常混淆从众与服从。从众通常没有明确的命令，且源于同伴影响；服从则需要一个公认的权威。切勿在未澄清区别的情况下互换使用这两个术语。
5. Attachment Theory | 依恋理论
Bowlby’s theory of attachment emphasises that infants have an innate need to form a strong emotional bond with a primary caregiver, usually the mother. This bond provides a secure base for exploration and is essential for healthy emotional development.
鲍尔比的依恋理论强调，婴儿天生需要与主要照顾者（通常是母亲）形成强烈的情感联结。这种联结为探索提供了安全基地，对健康的情感发展至关重要。
Ainsworth’s Strange Situation identified three main attachment types: secure (distress on separation, joy on reunion), insecure-avoidant (ignores caregiver) and insecure-resistant (clingy yet angry). A fourth type, disorganised, was later added.
安斯沃思的陌生情境法识别出三种主要依恋类型：安全型（分离时痛苦，重聚时喜悦）、不安全-回避型（忽视照顾者）和不安全-反抗型（粘人但愤怒）。后来增加了第四种，即紊乱型。
A common exam pitfall is labelling a child as ‘avoidant’ without linking behaviour to the reunion phase. In the Strange Situation, classification relies heavily on reunion behaviour, not just separation distress.
一个常见的考试陷阱是，仅凭分离时的行为就给孩子贴上“回避型”标签，而未联系重聚阶段的表现。在陌生情境法中，分类极大程度上依赖重聚行为，而不仅是分离时的痛苦。
6. Piaget’s Theory of Cognitive Development | 皮亚杰认知发展理论
Piaget proposed four stages: sensorimotor (0–2 years), pre-operational (2–7 years), concrete operational (7–11 years) and formal operational (11+ years). Year 7 students are typically entering the formal operational stage, capable of abstract and hypothetical thinking.
皮亚杰提出了四个阶段：感知运动阶段（0–2 岁）、前运算阶段（2–7 岁）、具体运算阶段（7–11 岁）和形式运算阶段（11 岁以上）。Year 7 学生通常正进入形式运算阶段，能够进行抽象和假设性思维。
Egocentrism and lack of conservation are hallmarks of the pre-operational stage. Conservation tasks (e.g. liquid, number) are classic: a child in this stage fails to understand that quantity remains the same despite changes in appearance.
自我中心主义和缺乏守恒能力是前运算阶段的标志。守恒任务（如液体、数量守恒）是经典实验：处于这一阶段的儿童无法理解尽管外观改变，但数量保持不变。
Exam tip: Do not simply name the stages. Describe a specific behaviour shown in a scenario and link it to the correct stage using Piagetian terminology, such as ‘reversibility’ or ‘decentration’.
考试提示：不要仅仅说出阶段名称。应描述场景中表现出的具体行为，并使用皮亚杰术语，如“可逆性”或“去中心化”，将其与正确的阶段联系起来。
7. Research Methods: Variables and Hypotheses | 研究方法：变量与假设
An independent variable (IV) is the factor manipulated by the researcher, while the dependent variable (DV) is what is measured. A hypothesis must be testable and clearly state the expected effect of the IV on the DV.
自变量是研究者操纵的因素，因变量是被测量的结果。假设必须是可检验的，并清晰陈述自变量对因变量的预期影响。
Students frequently confuse the IV and DV when given a research scenario. Phrases like ‘the IV is the DV because…’ show misunderstanding. Practise identifying what the experimenter changes (IV) and what they then record (DV).
学生在面对研究情境时经常混淆自变量和因变量。像“因为…所以自变量是因变量”这样的措辞表明理解有误。请练习识别实验者改变了什么（自变量），然后记录了什么（因变量）。
A good hypothesis uses precise language: ‘Participants who listen to music while studying will recall fewer words than those who study in silence’ states both the IV and DV clearly.
一个好的假设使用精确的语言：“学习时听音乐的参与者比在安静中学习的参与者回忆的单词更少”，这清楚地陈述了自变量和因变量。
8. Experimental Designs | 实验设计
| Design | Key Feature | Strength | Limitation |
|---|---|---|---|
| Independent groups | Different participants in each condition | No order effects | Participant variables may confound results |
| Repeated measures | Same participants in all conditions | Controls participant variables | Order effects (practice/boredom) |
| Matched pairs | Participants paired on key traits, then split | Reduces participant variables without order effects | Time-consuming and matching is never perfect |
A repeated measures design can suffer from order effects, but counterbalancing (half the participants do condition A first, half do condition B first) can help control them. Students often forget to mention counterbalancing when evaluating this design.
重复测量设计可能受顺序效应困扰，但平衡法（一半参与者先做条件 A，另一半先做条件 B）可以帮助控制。学生在评价该设计时常常忘记提及平衡法。
When describing an independent groups design, a frequent error is saying ‘participants were randomly allocated to avoid order effects’ – order effects are irrelevant here; random allocation controls participant variables.
在描述独立组设计时，一个常见错误是说“参与者被随机分配以避免顺序效应”——顺序效应在此并不相关；随机分配控制的是参与者变量。
9. Ethical Issues in Psychology | 心理学研究伦理
The British Psychological Society (BPS) sets ethical guidelines including informed consent, deception, right to withdraw, protection from harm, confidentiality and debriefing. Year 7 exam questions often ask you to identify ethical problems in a described study.
英国心理学会制定了伦理准则，包括知情同意、欺骗、退出权、免受伤害、保密和事后解释。Year 7 试题常要求你识别所描述研究中的伦理问题。
Deception should only be used when necessary and must be followed by a thorough debrief. Even then, some level of harm may be criticised. Milgram’s study raised serious ethical concerns because participants were deceived and exposed to extreme stress.
欺骗只有在必要时才可使用，且必须随后进行彻底的事后解释。即便如此，仍可能因造成某些伤害而受到批评。米尔格拉姆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大的压力。
Common slip: Suggesting that a study is unethical simply because participants were ‘unhappy’ for a moment. Instead, link the issue to a specific guideline, e.g. ‘This study breached the protection from harm principle because participants showed signs of distress such as trembling and sweating.’
常见疏忽：仅因参与者一时“不开心”就断定研究不伦理。正确的做法是将问题与具体准则挂钩，例如：“该研究违反了免受伤害原则，因为参与者表现出颤抖和出汗等痛苦迹象。”
10. Correlation vs Causation | 相关与因果的区分
A correlation is a relationship between two co-variables, expressed with a correlation coefficient ranging from −1 to +1. A positive correlation means both variables increase together; a negative correlation means as one increases, the other decreases.
相关是指两个共变因素之间的关系，用介于 −1 到 +1 的相关系数表示。正相关意味着两个变量同时增加；负相关意味着一个变量增加，另一个减少。
The most stubborn misconception is that correlation implies causation. Just because ice cream sales and drowning incidents both rise in summer does not mean ice cream causes drowning. A third variable, hot weather, explains the link.
最顽固的误解是认为相关意味着因果。冰淇淋销量与溺水事件在夏季同步上升，并不意味着冰淇淋导致溺水。第三个变量——炎热天气——解释了这一联系。
In exam answers, never say ‘this proves’ – use ‘suggests’ or ‘indicates’. Psychological research is rarely about proof; correlations allow predictions but not causal conclusions.
在考试答案中，绝不要说“这证明了”——应使用“表明”或“指示”。心理学研究很少涉及证明；相关能支持预测，但不能得出因果结论。
11. Common Pitfalls in Answering Exam Questions | 答题常见误区
Many marks are lost because students describe a study without applying it to the question. If a question asks ‘Explain how one study shows that leading questions affect memory’, you must state the IV, DV, results and then explicitly explain the link to leading questions.
许多分数丢失是因为学生描述了一项研究却没有将其应用于问题。如果题目要求“解释一项研究如何表明引导性问题影响记忆”，你必须陈述自变量、因变量、结果，然后明确解释与引导性问题的联系。
Vague language such as ‘memory gets worse’ earns few marks. Use psychological terms: ‘recall accuracy decreased’, ‘participants exhibited memory distortion’. Similarly, ‘the experiment was fair’ is meaningless; state which variable was controlled and how.
像“记忆力变差”这样的模糊表述得分很低。应使用心理学术语：“回忆准确性下降”、“参与者表现出记忆扭曲”。同样，“实验是公平的”毫无意义；应说明控制了哪个变量以及如何控制的。
Not reading the command word is a classic mistake. ‘Outline’ requires brief points; ‘Evaluate’ demands strengths and limitations; ‘Discuss’ expects a balanced argument with a conclusion. Writing a full evaluation when only an outline is needed wastes time.
忽略指令词是一个经典错误。“概述”要求简要列出要点；“评价”要求陈述优势和局限；“讨论”要求给出平衡论证并得出结论。当只需概述时却写出完整评价，会浪费宝贵时间。
12. Key Study Examples and Analysis | 经典研究案例与分析
Being able to cite key studies accurately can lift your answer. For cognitive development, Piaget’s conservation studies are fundamental. For social influence, Asch (1951, 1955, 1956) and Milgram (1963) are must-know references. For memory, Peterson and Peterson (1959) demonstrated STM duration using trigrams.
准确引用经典研究能提升你的答案水平。在认知发展方面，皮亚杰的守恒研究是基础。在社会影响方面，阿希（1951, 1955, 1956）和米尔格拉姆（1963）是必知文献。在记忆方面，彼得森夫妇（1959）用三字母组证明了短时记忆的持续时间。
Avoid the error of citing a study incorrectly – for instance, mixing up the findings of Asch and Milgram. Asch measured conformity to a unanimous but incorrect majority; Milgram measured obedience to an authority figure’s harmful orders. Keep their aims distinct.
避免错误引用研究——例如混淆阿希和米尔格拉姆的发现。阿希测量的是对一致却错误的大多数的从众行为；米尔格拉姆测量的是对权威人物有害指令的服从。务必区分二者的目的。
When evaluating studies, comment on ecological validity, sample bias and ethics. For example, Asch’s study used male American undergraduates in a laboratory setting, limiting generalisability to real-life conformity and to other cultures or genders.
在评价研究时，应评述生态效度、样本偏差和伦理。例如，阿希的研究在实验室中使用美国男大学生，这限制了对现实从众行为以及其它文化或性别的可推广性。
