📚 A-Level CAIE Psychology: Complete Syllabus Breakdown | A-Level CAIE 心理学：课程大纲全面解析
Cambridge International A-Level Psychology (9990) gives learners a structured introduction to the scientific study of mind and behaviour. The syllabus is built around four core approaches, research methodology, key issues and debates, and a choice of specialist options that apply psychology to real-world settings. It is a linear qualification, so the AS content is examined at the end of the first year and the full A Level at the end of the second, with no modular re-sits in between.
剑桥国际 A-Level 心理学（9990）为学生提供了一套系统的心理学科学入门。课程围绕四个核心流派、研究方法、关键问题与争论，以及可选的专题方向展开，将心理学应用于现实情境。它属于线性（linear）资格，AS 内容在第一年结束时考核，完整 A Level 在第二年结束时考核，中间不设模块化补考。
1. Course Overview and Aims | 课程概览与目标
The course aims to develop both knowledge of psychological concepts and the ability to evaluate theories and research evidence. Learners are encouraged to think critically, design simple investigations, and recognise the ethical and cultural dimensions of psychology.
本课程旨在培养学生对心理学概念的掌握以及对理论和研究证据的评价能力。课程鼓励学生进行批判性思考、设计简单研究，并关注心理学中的伦理与文化维度。
More specifically, the syllabus asks candidates to: understand and apply psychological theories, concepts and methods; analyse and evaluate studies rather than simply memorise them; plan and justify their own small-scale investigations; and communicate arguments using appropriate terminology and evidence.
更具体地说，大纲要求考生：理解并运用心理学理论、概念与方法；分析并评价研究，而非单纯记忆；设计并论证自己的小型研究；使用恰当的术语与证据表达论证。
- AO1 Knowledge and understanding of psychological concepts, theories and studies.
- AO2 Application of psychological knowledge to familiar and unfamiliar scenarios.
- AO3 Analysis and evaluation of theories, studies, methods and evidence.
- AO1 对心理学概念、理论与研究的认识与理解。
- AO2 将心理学知识应用于熟悉与陌生的情境。
- AO3 对理论、研究、方法及证据进行分析与评价。
2. Syllabus Structure and Assessment | 大纲结构与考核方式
The specification is linear and covers AS and A Level content over two years. AS candidates sit two papers; A Level candidates sit four. Each paper is 1 hour 30 minutes and worth 60 marks, and at A Level the four papers carry equal weight, so no single paper can be neglected during revision.
该大纲为线性结构，用两年时间覆盖 AS 与 A Level 内容。AS 考生考两张试卷，A Level 考生考四张。每张试卷时长 1 小时 30 分钟、满分 60 分；在 A Level 阶段四张试卷权重相同，因此复习时不能偏废任何一张。
| Paper | Content | Level | Marks |
| Paper 1 | Approaches, Issues and Debates | AS + A Level | 60 |
| Paper 2 | Research Methods | AS + A Level | 60 |
| Paper 3 | Specialist Options (Theory) | A Level only | 60 |
| Paper 4 | Specialist Options (Application) | A Level only | 60 |
Paper 1 uses short structured questions on the approaches and on issues and debates. Paper 2 is scenario-based: candidates read a description of a study and answer methodological questions, including a design question. Papers 3 and 4 examine two chosen specialist options, with Paper 4 focusing on applied, novel scenarios.
Paper 1 以短小的结构化题目考查各流派及议题与争论。Paper 2 基于情境：考生阅读一段研究描述并回答方法论问题，其中包含一道研究设计题。Paper 3 与 Paper 4 考查所选的两个专题方向，其中 Paper 4 侧重应用与新颖情境。
It provides a foundation for university study in psychology, sociology, education, criminology, nursing, marketing and other social-science or health-related degrees, and it develops transferable skills in data interpretation and argumentation.
它为大学阶段攻读心理学、社会学、教育学、犯罪学、护理学、市场营销等社会科学或健康相关专业奠定基础，同时培养数据解读与论证等可迁移能力。
3. The Four Core Approaches | 四大核心流派
The syllabus is organised around four approaches: biological, cognitive, learning and social. Each approach has its own assumptions, typical methods, classic studies and strengths and weaknesses, and exam questions frequently ask candidates to compare one approach with another.
大纲围绕四大流派组织：生物取向、认知取向、学习取向与社会取向。每个流派都有自己的基本假设、典型方法、经典研究以及优缺点，考试中经常要求考生比较两个流派。
- Biological: behaviour explained through genes, hormones, neurotransmitters and brain structure; methods include brain scanning, twin studies and animal research.
- Cognitive: behaviour explained through internal mental processes such as memory, attention and schemas; methods include laboratory experiments and case studies of brain injury.
- Learning: behaviour explained through conditioning, reinforcement, observation and imitation; methods include laboratory and natural experiments.
- Social: behaviour explained through the influence of others, groups, norms and situations; methods include field experiments and observations.
- 生物取向：以基因、激素、神经递质和脑结构解释行为；方法包括脑成像、双生子研究与动物研究。
- 认知取向：以记忆、注意、图式等内部心理过程解释行为；方法包括实验室实验与脑损伤个案研究。
- 学习取向：以条件作用、强化、观察与模仿解释行为；方法包括实验室实验与自然实验。
- 社会取向：以他人、群体、规范与情境的影响解释行为；方法包括现场实验与观察法。
A strong answer does not just describe an approach; it uses evidence from named studies and evaluates the methodology that produced that evidence.
高分答案不会只描述某个流派，而会引用具名研究的证据，并对产生该证据的方法论进行评价。
4. Research Methodology | 研究方法
Research methods is examined on Paper 2 and is also embedded throughout the other papers, because every study discussed in class has a method that can be criticised. Candidates must be able to design, describe, justify and evaluate investigations.
研究方法在 Paper 2 中专门考查，同时也贯穿其他试卷，因为课堂上讨论的每一项研究都有可被批评的方法。考生必须能够设计、描述、论证并评价研究。
- Experiments: laboratory, field, natural and quasi-experiments; independent measures, repeated measures and matched pairs.
- Self-reports: questionnaires, structured and unstructured interviews, rating scales.
- Observations: naturalistic, controlled, participant and non-participant, overt and covert.
- Correlational studies, case studies, longitudinal and cross-sectional designs.
- Sampling: random, opportunity, volunteer, systematic and stratified.
- Data: nominal, ordinal and interval; primary and secondary.
- 实验：实验室实验、现场实验、自然实验与准实验；独立组、重复测量与配对设计。
- 自我报告：问卷、结构化与非结构化访谈、评定量表。
- 观察：自然观察、控制观察、参与与非参与观察、公开与隐蔽观察。
- 相关研究、个案研究、纵向与横断设计。
- 抽样：随机抽样、机会抽样、自愿抽样、系统抽样与分层抽样。
- 数据：称名数据、顺序数据与等距数据；一手数据与二手数据。
Descriptive statistics must be calculated and interpreted. The mean, median and mode describe central tendency, while the range and standard deviation describe dispersion:
描述统计必须会计算并解释。平均数、中位数和众数描述集中趋势，全距与标准差描述离散程度：
mean: x̄ = Σx ÷ n | standard deviation: s = √( Σ(x − x̄)² ÷ (n − 1) )
Ethical guidelines run through the whole paper: informed consent, deception, protection from harm, confidentiality, privacy, right to withdraw, and the use of animals. Reliability (consistency) and validity (measuring what is claimed) must be distinguished clearly, since examiners award marks for using these terms precisely rather than loosely.
伦理准则贯穿整张试卷：知情同意、欺骗、免于伤害、保密、隐私、退出权以及动物使用。信度（一致性）与效度（是否测量了所要测量的内容）必须清楚区分，因为考官只会给术语使用准确的答案加分，而非含糊使用的答案。
5. Key Issues and Debates | 关键议题与争论
Issues and debates provide the evaluative backbone of the course. They are not a separate topic to memorise in isolation; they are the lens through which theories and studies are judged on Paper 1 and again in the specialist options.
议题与争论构成了整门课程的评价性主干。它们不是需要孤立记忆的独立主题，而是 Paper 1 以及专题方向中评判理论与研究的透镜。
- Nature versus nurture: is behaviour caused by biology, by experience, or by an interaction?
- Free will versus determinism: can people choose, or is behaviour caused?
- Reductionism versus holism: should behaviour be broken into parts or studied as a whole?
- Individual versus situational explanations of behaviour.
- Cultural bias: do findings generalise beyond Western, educated samples?
- Ethical costs of research versus scientific benefits.
- Social control and the application of psychology to everyday life.
- Is psychology a science? Consider objectivity, replicability and falsifiability.
- 先天与后天：行为由生物因素、经验，还是两者交互作用造成？
- 自由意志与决定论：人能否自主选择，行为是否被决定？
- 还原论与整体论：应把行为拆成部分，还是作为整体研究？
- 行为的个体解释与情境解释。
- 文化偏差：研究结论能否推广到西方受教育样本之外？
- 研究的伦理代价与科学收益之间的权衡。
- 社会控制，以及心理学在日常生活中的应用。
- 心理学是不是科学？可从客观性、可重复性与可证伪性考虑。
In the exam, these debates should be used actively: 'This study is reductionist because it explains memory purely in terms of one brain region, which means it may underestimate the role of social context' is far stronger than simply naming the debate.
在考试中，这些争论应被主动使用：'该研究是还原论的，因为它仅用一个脑区解释记忆，因此可能低估社会情境的作用'，远比只写出争论名称得分更高。
6. Specialist Options | 专题选修方向
At A Level, candidates study two specialist options in depth. Each option applies the four approaches to a real-world domain, and exam questions may require candidates to draw on any relevant approach rather than only the most obvious one.
在 A Level 阶段，考生需深入学习两个专题方向。每个方向都把四大流派应用于某个现实领域，考试题目可能要求考生调用任何相关流派，而不只是最显而易见的那一个。
| Option | Typical content |
| Psychology and Abnormality | Definitions of abnormality, classification and diagnosis, explanations and treatments of disorders such as depression and schizophrenia. |
| Psychology and Consumer Behaviour | Persuasion, advertising, shopping behaviour, brand loyalty, the influence of music and packaging. |
| Psychology and Health | Stress and illness, doctor-patient communication, adherence to treatment, health promotion and pain. |
| Psychology and Organisations | Leadership, motivation, group decision making, job satisfaction, work-related stress and selection. |
The option list is set by Cambridge and has historically included the four areas above; candidates should always confirm the current list in the version of the syllabus they are sitting, since options can be reviewed between syllabus cycles.
专题列表由剑桥设定，历史上通常包含上述四个领域；考生应始终以自己所在考试周期的现行大纲为准，因为专题可能在不同大纲周期之间调整。
Paper 4 makes this section harder than Paper 3. It presents unfamiliar applied scenarios, such as designing an intervention for a hospital, and expects candidates to select and justify psychological ideas rather than simply recite a chapter.
Paper 4 使这一部分的难度高于 Paper 3。它会给出陌生的应用情境，例如为一家医院设计干预方案，要求考生选择并论证心理学观点，而不是单纯背诵课本内容。
7. Named Studies and Their Role | 具名研究及其作用
The course is evidence-based, so named studies appear inside each approach and each option. They are the raw material for AO2 and AO3 questions, and candidates are expected to know aims, procedures, findings and conclusions accurately.
本课程以证据为基础，因此每个流派和每个专题中都会出现具名研究。它们是 AO2 与 AO3 题目的原材料，考生需要准确掌握研究目的、程序、结果与结论。
- Biological: Sperry's split-brain work, Maguire's taxi-driver study, twin studies of intelligence, animal studies of attachment.
- Cognitive: Loftus and Palmer on eyewitness memory, Bartlett on reconstructive memory, case studies of amnesia.
- Learning: Pavlov and Skinner on conditioning, Bandura on observational learning and aggression, Watson and Rayner on conditioned fear.
- Social: Milgram on obedience, Zimbardo's prison study, Asch on conformity, Piliavin on bystander behaviour.
- 生物取向：Sperry 的裂脑研究、Maguire 的出租车司机研究、智力的双生子研究、依恋的动物研究。
- 认知取向：Loftus 与 Palmer 的目击者记忆研究、Bartlett 的重构记忆研究、失忆症个案研究。
- 学习取向：Pavlov 与 Skinner 的条件作用、Bandura 的观察学习与攻击性、Watson 与 Rayner 的条件性恐惧。
- 社会取向：Milgram 的服从研究、Zimbardo 的监狱实验、Asch 的从众研究、Piliavin 的旁观者行为研究。
For each study, prepare a four-part card: methodology, results, conclusions and evaluation (ethics, validity, reliability, sample, culture, usefulness). This one habit answers a large proportion of exam questions.
为每项研究准备一张四栏卡片：方法、结果、结论与评价（伦理、效度、信度、样本、文化、实用性）。这一习惯可以应对考试中相当大比例的题目。
8. AS Level: The First Year | 第一年：AS 阶段
The AS year establishes the foundations. Candidates meet the four approaches, learn the vocabulary of research methods, and begin to write evaluative answers rather than descriptive ones.
AS 这一年打基础。考生接触四大流派、掌握研究方法术语，并开始写出评价性而非描述性的答案。
- Term 1: biological and cognitive approaches, with their key studies and applications.
- Term 2: learning and social approaches, plus the main issues and debates.
- Term 3: research methods in depth (design, sampling, ethics, data, statistics) and past-paper practice.
- 第一学期：生物取向与认知取向，及其关键研究与应用。
- 第二学期：学习取向与社会取向，以及主要议题与争论。
- 第三学期：深入研究方法（设计、抽样、伦理、数据、统计）并进行真题训练。
AS grades do not automatically carry forward into the A Level result under a linear structure, but the content does: everything learned in year one can be examined in the final Paper 1 and Paper 2. A weak first year cannot be repaired by last-minute revision alone.
在线性结构下，AS 成绩不会自动计入 A Level 总成绩，但内容会：第一年所学的全部内容都可能在最终的 Paper 1 与 Paper 2 中考查。第一年基础薄弱，仅靠最后冲刺难以弥补。
9. A Level: The Second Year | 第二年：A Level 阶段
In the second year the emphasis shifts from breadth to depth. Candidates consolidate the four approaches, strengthen their handling of issues and debates, and study two specialist options for Papers 3 and 4.
第二年，重心从广度转向深度。考生巩固四大流派、强化对议题与争论的运用，并为 Paper 3 与 Paper 4 学习两个专题方向。
A useful second-year routine is to build an 'options matrix' that maps each option against the four approaches. Many strong Paper 4 answers gain marks precisely by bringing an unexpected approach to an applied problem, such as using learning theory to explain adherence to a medical regime.
第二年一个有效的习惯是制作'专题—流派矩阵'，把每个专题与四大流派对应起来。许多高分 Paper 4 答案正是通过把意想不到的流派用于应用问题而得分，例如用学习理论解释患者对治疗方案的依从性。
Synoptic thinking is the main new demand: questions rarely say 'use the biological approach', so candidates must decide for themselves which approach, study and debate will produce the most convincing argument in the time available.
综合性思维是新的主要要求：题目很少直接说'请使用生物取向'，考生必须自行判断哪个流派、哪项研究与哪个争论能在有限时间内形成最有说服力的论证。
10. Assessment Objectives and Command Words | 考核目标与指令词
Marks are allocated to assessment objectives, and each objective demands a different style of writing. Command words in the question tell candidates which objective is being targeted, so misreading them is one of the most common causes of lost marks.
分数按考核目标分配，每个目标要求不同的写作方式。题干中的指令词会提示该题针对哪个目标，因此误读指令词是失分最常见的原因之一。
- Describe, outline, state, give: AO1 — accurate, concise knowledge.
- Explain, apply, suggest: AO2 — link concepts to the scenario given.
- Evaluate, discuss, assess, to what extent, compare: AO3 — strengths, weaknesses, evidence, conclusion.
- Describe、outline、state、give：AO1——准确、简洁的知识。
- Explain、apply、suggest：AO2——把概念与所给情境联系起来。
- Evaluate、discuss、assess、to what extent、compare：AO3——优点、缺点、证据与结论。
AO2 answers must use the material in the scenario. A generic paragraph about Milgram earns AO1 credit but no application marks, whereas 'the nurse in the scenario followed the senior doctor's instruction, which mirrors the agentic shift described by Milgram' earns both.
AO2 的答案必须使用情境中的材料。一段泛泛而谈的 Milgram 段落只能得 AO1 分，得不到应用分；而'情境中的护士听从了资深医生的指示，这正对应 Milgram 所描述的代理状态转变'则可同时得分。
AO3 answers need balance and a judgement. Listing three weaknesses without deciding which matters most usually caps the mark, because the assessment objective explicitly includes reaching a supported conclusion.
AO3 的答案需要平衡与判断。只罗列三个缺点而不指出哪一个最重要，通常会限制得分，因为该考核目标明确包含'得出有依据的结论'。
11. Revision Strategy and Exam Technique | 复习策略与应试技巧
Psychology rewards active recall and structured writing far more than re-reading notes. Effective revision converts content into answers, under timed conditions, with examiner-style feedback.
心理学更奖励主动回忆与结构化写作，而非反复阅读笔记。有效的复习是在限时条件下把内容转化为答案，并获得类似考官的反馈。
- Build a study bank: aim, method, results, conclusion, evaluation for every named study.
- Build a debate bank: one paragraph for each debate, with two studies as evidence on each side.
- Practise design questions from memory, then check against mark schemes.
- Time your answers: roughly 1.5 minutes per mark leaves a few minutes for checking.
- Learn to define reliability, validity, ethics, objectivity and generalisability in one precise sentence each.
- 建立研究库：为每项具名研究整理目的、方法、结果、结论与评价。
- 建立争论库：每个争论写一段，正反各用两项研究作证据。
- 凭记忆练习研究设计题，再对照评分标准检查。
- 训练答题速度：大约每分 1.5 分钟，留出几分钟检查。
- 把信度、效度、伦理、客观性与可推广性各用一句精确的话定义清楚。
For extended evaluation questions, use a simple skeleton: point, evidence from a named study, explanation of why it matters, and a link back to the question. This structure keeps answers coherent under pressure and makes it easy for examiners to award marks.
对于长篇评价题，使用简单框架：观点、来自具名研究的证据、说明为何重要、再回扣题目。这一结构能让答案在压力下依然连贯，也便于考官给分。
Finally, avoid unsupported claims. 'Studies show that...' earns nothing; 'Loftus and Palmer found that leading questions altered speed estimates, which suggests memory is reconstructive' earns credit because it names the evidence and draws a conclusion.
最后，避免无证据的断言。'研究表明……'得不到分；'Loftus 与 Palmer 发现引导
