1. What is Psychology? | 什么是心理学？
Psychology is the scientific study of mind and behaviour. It uses systematic observation, measurement, and experimentation to understand why people think, feel, and act the way they do. Unlike everyday ‘common sense’, psychological conclusions are based on empirical evidence gathered through controlled research.
心理学是对心理和行为的科学研究。它运用系统的观察、测量和实验来理解人们为何以特定的方式思考、感受和行动。与日常的“常识”不同，心理学的结论建立在通过严谨研究收集的实证证据之上。
Key areas of psychology include cognitive (how we process information), developmental (how we change over the lifespan), social (how we interact with others), and biological (how brain and body influence behaviour). In Year 9, you will touch on several of these domains, building a broad foundation for future study.
心理学的主要领域包括认知心理学（我们如何处理信息）、发展心理学（我们如何随着年龄增长而变化）、社会心理学（我们如何与他人互动）以及生理心理学（大脑和身体如何影响行为）。在九年级，你会接触到其中好几个领域，为未来的学习打下宽广的基础。
2. Research Methods in Psychology | 心理学研究方法
Psychologists use a variety of research methods to investigate behaviour. A core method is the experiment, where an independent variable (IV) is manipulated to see its effect on a dependent variable (DV), while all other variables are controlled. This allows researchers to establish cause–and–effect relationships.
心理学家使用多种研究方法来探究行为。其中最核心的方法是实验法，通过操纵自变量（IV）来观察其对因变量（DV）的影响，同时控制其他所有变量。这使得研究者能够建立起因果关系。
Other important methods include observations, where behaviour is watched and recorded in a natural or controlled setting, and questionnaires, which gather self-reported attitudes or experiences. Case studies involve in-depth examination of a single individual or small group, often providing rich detail but limited generalisability.
其他重要方法包括在自然或受控情境中观察并记录行为的观察法，以及收集自述态度或体验的问卷法。个案研究则是对单个个体或小群体进行深入考查，常常能提供丰富的细节，但其结论的普遍性有限。
In all methods, variables must be operationalised—clearly defined in measurable terms. Reliability refers to consistency of results, while validity concerns whether a study truly measures what it claims to measure.
在所有方法中，变量都必须操作化——即用可测量的术语进行清晰定义。信度指的是结果的一致性，而效度关注的是一项研究是否真正测量了它声称要测量的东西。
3. Ethical Guidelines | 研究伦理准则
When conducting research with human participants, psychologists must follow strict ethical guidelines. The British Psychological Society (BPS) outlines key principles, including informed consent, right to withdraw, confidentiality, protection from harm, and debriefing. Participants should agree to take part knowing what the study involves and must be allowed to leave at any time without penalty.
在对人类参与者进行研究时，心理学家必须遵守严格的伦理准则。英国心理学会（BPS）提出了包括知情同意、中途退出权、保密、避免伤害和事后解释在内的核心原则。参与者应在了解研究内容后自愿同意参加，并有权随时退出而不受任何惩罚。
Confidentiality means personal data should be kept private, and no individual should be identifiable in published research. Debriefing after the study involves explaining the true aims and restoring the participant to their original state. These ethical practices safeguard both the participants’ welfare and the integrity of psychological research.
保密意味着个人数据应当被保护，已发表的研究中不应可识别出任何个体。研究结束后的事后解释包括告知真实目的，并使参与者恢复至原有状态。这些伦理做法既保护了参与者的福祉，也维护了心理学研究的诚信。
4. The Multi-Store Model of Memory | 记忆的多储存模型
Memory involves encoding, storing, and retrieving information. Atkinson and Shiffrin’s Multi-Store Model (MSM) describes three separate stores: sensory register, short-term memory (STM), and long-term memory (LTM). Information flows between them through attention and rehearsal.
记忆涉及信息编码、储存和提取的过程。Atkinson 和 Shiffrin 提出的多储存模型（MSM）描述了三个独立的储存库：感觉登记、短时记忆（STM）和长时记忆（LTM）。信息通过注意和复述在这些储存库之间流动。
| Store 储存库 | Capacity 容量 | Duration 持续时间 | Coding 编码方式 |
|---|---|---|---|
| Sensory Register 感觉登记 | Very large 非常大 | <0.5 seconds 小于0.5秒 | Sense-specific 特定感官 |
| Short-Term Memory 短时记忆 | 7 ± 2 items 7±2个组块 | 18-30 seconds 18-30秒 | Acoustic 声音 |
| Long-Term Memory 长时记忆 | Potentially unlimited 潜无限 | Lifetime 一生 | Semantic 语义 |
Rehearsal, especially elaborative rehearsal linking new information to existing knowledge, helps transfer material into LTM. Forgetting can occur through decay, displacement, or retrieval failure. The MSM remains a foundational but simplified explanation of memory structure.
复述，尤其是将新信息与已有知识相联系的精细复述，有助于将材料转入长时记忆。遗忘可能由于衰退、干扰或提取失败而发生。多储存模型至今仍是关于记忆结构的基础性解释，尽管相对简化。
5. Understanding Attachment | 理解依恋
Attachment is a deep emotional bond between an infant and their primary caregiver. John Bowlby argued that this bond has an evolutionary basis, keeping infants close to caregivers for survival. A secure attachment provides a ‘secure base’ from which a child can explore the world.
依恋是婴儿与其主要照料者之间深厚的情感纽带。John Bowlby 认为这种纽带具有进化基础，能让婴儿靠近照料者以确保生存。安全型依恋为儿童提供了一个可以探索世界的“安全基地”。
Mary Ainsworth developed the ‘Strange Situation’ technique to identify different attachment types. Observing how infants respond to brief separations and reunions with their caregiver revealed three main patterns: secure, insecure-avoidant, and insecure-resistant (ambivalent). A fourth type, disorganised, was later added.
Mary Ainsworth 设计了“陌生情境”技术来识别不同的依恋类型。通过观察婴儿对短暂分离和与照料者重聚的反应，揭示出三种主要模式：安全型、不安全-回避型和不安全-矛盾型。后来增加了第四种类型——紊乱型。
| Attachment Type 依恋类型 | Exploration Behaviour 探索行为 | Response to Reunion 重聚反应 |
|---|---|---|
| Secure 安全型 | Explores freely, uses caregiver as safe base 自由探索，以照料者为安全基地 | Seeks comfort, quickly soothed 寻求安慰，很快被安抚 |
| Insecure-Avoidant 不安全-回避型 | Explores without seeking proximity 探索时不寻求亲近 | Ignores or avoids caregiver on return 返回时忽视或回避照料者 |
| Insecure-Resistant 不安全-矛盾型 | Reluctant to explore, clingy 不愿探索，黏人 | Simultaneously seeks and resists comfort 同时寻求又抗拒安抚 |
Early attachment patterns can influence later social and emotional development, though life experiences may bring about change. Bowlby’s concept of the ‘internal working model’ suggests that first attachments form a mental template for future relationships.
早期依恋模式可能影响后续的社会情感发展，尽管生活经历也可能带来改变。Bowlby 的“内部工作模型”概念指出，最初的依恋会形成未来人际关系的一种心理模板。
6. Conformity and Obedience | 从众与服从
Social influence describes how our behaviour is affected by others. Conformity is yielding to group pressure, changing one’s beliefs or actions to fit with the majority. Solomon Asch’s line judgement experiment (1951) demonstrated that even on simple tasks, participants often gave incorrect answers to conform with a unanimous majority, showing the power of normative social influence.
社会影响描述的是我们的行为如何受他人影响。从众就是屈从于群体压力，改变自己的信念或行为以符合多数人的标准。Solomon Asch 的线段判断实验（1951年）证明，即使在简单任务中，参与者为了与一致的大多数保持一致，也常常给出错误答案，显示了规范性社会影响的强大力量。
Obedience is following orders from an authority figure. Stanley Milgram’s famous electric shock experiment (1963) found that a high proportion of participants obeyed an experimenter’s commands to deliver what they believed were dangerous shocks to a learner. Obedience rates were much higher than experts had predicted, highlighting the immense influence of perceived legitimate authority.
服从则是遵从权威人物的命令。Stanley Milgram 著名的电击实验（1963年）发现，极高比例的参与者遵从实验者的命令，对学习者施加他们认为危险的点击。服从率远高于专家预测，凸显了感知到的合法权威所带来的巨大影响力。
Factors such as proximity of the authority figure, prestige of the setting, and having disobedient role models all affect obedience levels. Understanding these classic studies helps us recognise the situational factors driving ordinary people to follow harmful orders.
权威人物的近距离在场、环境的声望以及拥有不服从的榜样等因素，都会影响服从程度。理解这些经典研究有助于我们认识到，是哪些情境因素驱使普通人去执行有害命令。
7. Prejudice and Discrimination | 偏见与歧视
Prejudice is a negative, often unfounded attitude towards an individual based solely on their membership of a particular group. Discrimination refers to actual behaviour that treats people unfairly because of their group membership. Stereotypes are oversimplified, fixed beliefs about categories of people.
偏见是一种仅基于个体所属群体而产生的、通常并无根据的负面态度。歧视则是指因群体身份而以不公平方式对待他人的实际行为。刻板印象是对特定人群类别过度简化且僵化的固定看法。
The ‘Robbers Cave’ experiment by Sherif showed how competition can quickly create intergroup hostility, prejudice, and ingroup favouritism. Conversely, working towards shared goals through superordinate objectives reduced tension between the groups. This suggests that cooperative contact can diminish prejudice.
Sherif 的“强盗洞”实验展示了竞争如何迅速制造群体间敌意、偏见和内群偏爱。相反，通过超然目标共同合作则减轻了群体间的紧张关系。这表明合作性的接触可以减少偏见。
Contact theory, refined by Allport, argues that prejudice can be reduced when groups have equal status, common goals, intergroup cooperation, and support from authorities. Education and critical thinking about stereotypes also play key roles in tackling prejudiced attitudes.
由 Allport 完善的接触理论指出，当群体地位平等、目标一致、群体间合作并得到权威支持时，偏见便可以被削弱。针对刻板印象的教育和批判性思考在消除偏见态度中也起着关键作用。
8. Nature versus Nurture | 先天与后天之争
The nature–nurture debate examines whether behaviour is primarily determined by genetic inheritance (nature) or by environment, learning, and experience (nurture). In reality, almost all psychological traits involve a complex interplay between the two.
先天与后天之争探讨的是，行为究竟主要由遗传基因（先天）决定，还是由环境、学习和经历（后天）所决定。实际上，几乎所有的心理特质都涉及这两者之间复杂的相互作用。
Proponents of the nature perspective point to twin studies showing that identical twins reared apart often share remarkable similarities in intelligence, personality, and mental health, supporting a genetic influence. The nurture argument highlights the impact of parenting styles, education, and culture, demonstrating that enriched environments can raise IQ and alter behaviour patterns.
先天论的支持者指出，双生子研究显示分开抚养的同卵双胞胎在智力、人格和心理健康方面往往有着惊人的相似性，这支持了遗传的影响。后天论证则强调教养方式、教育和文化的作用，表明丰富的环境可以提高智商并改变行为模式。
Contemporary psychology adopts an interactionist stance, acknowledging that nature gives us potential, but nurture shapes how that potential is expressed. Epigenetics shows that environmental factors can even affect how genes are switched on or off, blurring the line between nature and nurture.
当代心理学采纳了交互作用论的立场，承认先天赋予我们潜能，但后天塑造着潜能如何被表达。表观遗传学表明，环境因素甚至能影响基因的开启或关闭，从而模糊了先天与后天之间的界限。
9. Introduction to Mental Health | 心理健康入门
Mental health refers to our emotional, psychological, and social well-being. It affects how we think, feel, and behave, as well as how we handle stress and relate to others. Being mentally healthy is not just the absence of a diagnosed disorder; it also involves resilience and the ability to enjoy life.
心理健康指的是我们情绪、心理和社交方面的完好状态。它影响着我们的思考、感受和行为方式，也影响我们如何应对压力和与他人相处。心理健康并不仅仅意味着没有确诊的疾病，它还包括心理韧性以及享受生活的能力。
Stigma around mental health can prevent young people from seeking help. Understanding common conditions like anxiety and depression in a factual, empathetic way reduces stereotypes and encourages support-seeking behaviour. Open conversations and self-care strategies are vital tools for maintaining well-being.
围绕心理健康的污名化可能会阻碍年轻人主动寻求帮助。以基于事实且富有同理心的方式去了解焦虑和抑郁等常见问题，有助于减少刻板印象并鼓励求助行为。开放对话和自我关怀策略是守护心理健康的重要工具。
Year 9 provides a safe space to explore basic psychological concepts related to stress, coping, and the importance of social support. Recognising that mental health exists on a continuum and can change over time is an empowering realisation for all students.
九年级的学习提供了一个安全的空间，去探索与压力、应对以及社会支持重要性相关的基础心理学概念。认识到心理健康是一个动态连续谱且会随时间发生变化，这对所有学生来说都是一个充满力量的认识。
