1. Introduction to the Syllabus | 课程大纲介绍
The Cambridge IGCSE Psychology syllabus (0266) is designed to develop an understanding of psychological concepts, theories, and research techniques. It encourages students to think scientifically about behaviour, while appreciating ethical considerations and real-world applications.
剑桥 IGCSE 心理学大纲（0266）旨在培养学生对心理学概念、理论和研究方法的理解。课程鼓励学生以科学的方式思考行为，同时重视伦理考量与现实应用。
The course is built around five core topics that cover cognitive, biological, social, and developmental perspectives. No prior knowledge of psychology is required, making it an accessible yet rigorous subject for 14- to 16-year-old students worldwide.
课程围绕五个核心主题展开，涵盖认知、生物、社会和发展等视角。学习本课程无需心理学基础，这一设计使全球 14 至 16 岁的学生都能入门兼具挑战性的心理学。
2. Assessment Structure and Grading | 评估结构与评分
All candidates take two written papers. Paper 1 ('Studies and Applications in Psychology 1') lasts 1 hour 30 minutes, carries 80 marks, and contributes 50% of the final grade. It assesses the five core topics through short-answer and extended-response questions.
所有考生需参加两份笔试。试卷一（“心理学研究与运用 1”）时长 1 小时 30 分钟，满分为 80 分，占最终成绩的 50%。该卷通过简答题和论述题考查五个核心主题。
Paper 2 ('Studies and Applications in Psychology 2') is equally weighted at 50%, with 80 marks in 1 hour 30 minutes. This paper focuses more heavily on research methods, data handling, and the application of knowledge to novel scenarios while still drawing on the core content.
试卷二（“心理学研究与运用 2”）同样占 50%，80 分，1 小时 30 分钟。该卷更侧重研究方法、数据处理以及将知识应用于新情境的能力，但仍以核心内容为基础。
Both papers require knowledge of the same five topics, but Paper 2 typically presents unseen source material and requires students to evaluate studies, describe ethical issues, or design simple investigations.
两份试卷都考查相同的五个主题，但试卷二通常会给出未见过的资料，要求学生评价研究、描述伦理问题或设计简单的调查。
3. Topic A: Memory – Models and Forgetting | 主题 A：记忆——模型与遗忘
The memory topic explores how information is encoded, stored, and retrieved. Students study the multi-store model (Atkinson and Shiffrin) and the working memory model (Baddeley and Hitch), comparing their features and supporting evidence.
记忆主题探讨信息如何被编码、储存和提取。学生学习多储存模型（Atkinson 和 Shiffrin）与工作记忆模型（Baddeley 和 Hitch），比较两者特点及支撑证据。
Key research includes Peterson and Peterson's study on short-term memory duration using trigrams, and Bartlett's 'War of the Ghosts' experiment, which demonstrated reconstructive memory and cultural schemas. Understanding these studies helps students evaluate models critically.
关键研究包括 Peterson 和 Peterson 使用无意义音节对短时记忆时长的实验，以及 Bartlett 的“幽灵之战”实验，后者表明了记忆的重构性和文化图式影响。理解这些研究有助于批判性地评价模型。
Theories of forgetting are also covered, notably interference theory (proactive and retroactive) and context-dependent forgetting. Students must explain how retrieval failure or competing information can lead to memory loss.
遗忘理论也是学习内容，主要有干扰理论（前摄抑制与倒摄抑制）以及情境依赖遗忘。学生需要解释提取失败或信息竞争为何会导致记忆遗失。
4. Topic B: Perception – Sensation and Interpretation | 主题 B：感知——感觉与解释
Perception examines how we interpret sensory information. The syllabus distinguishes between sensation (the physical process) and perception (the psychological interpretation), using visual illusions and depth cues as core examples.
感知章节探究我们如何解读感觉信息。大纲区分了感觉（物理过程）和感知（心理解释），并利用视错觉和深度线索作为核心实例。
Students learn about monocular depth cues, such as linear perspective, relative size, and texture gradient, which help us judge distance. Pictorial cues are analysed through classic illusions like the Muller-Lyer and Ponzo illusions.
学生了解单眼深度线索，例如线条透视、相对大小和纹理梯度，这些帮助判断距离。通过穆勒-莱耶错觉和潘佐错觉等经典错觉分析图像线索。
The constructivist theory (Gregory) and direct theory (Gibson) are compared. Gregory emphasises top-down processing using prior knowledge, while Gibson argues that perception is direct and based on affordances in the environment.
建构主义理论（Gregory）与直接理论（Gibson）被加以对比。Gregory 强调基于已有知识的自上而下加工，而 Gibson 认为感知是直接的，基于环境中的功能可提供性。
Important studies include Haber and Levin's investigation of size constancy and familiarity, and research by Kanizsa on subjective contours, which supports the idea that perception is an active construction.
重要研究有 Haber 和 Levin 对大小恒常性与熟悉度的探究，以及 Kanizsa 对主观轮廓的研究，后者支持感知是主动建构的观点。
5. Topic C: Development – Cognitive Changes Across Childhood | 主题 C：发展——儿童期认知变化
This topic focuses on cognitive development, primarily through the work of Jean Piaget. Students examine his stage theory, including the sensorimotor, pre-operational, concrete operational, and formal operational stages, and the key milestones within each.
本主题聚焦认知发展，主要通过让·皮亚杰的研究展开。学生需要学习他的阶段理论，包括感知运动阶段、前运算阶段、具体运算阶段和形式运算阶段，以及各自的关键里程碑。
Conservation tasks are a central part of the syllabus. The classic Piagetian experiments on conservation of number, volume, and mass are analysed, along with critiques such as McGarrigle and Donaldson's 'naughty teddy' study, which suggests younger children can conserve under child-friendly conditions.
守恒任务是课程的核心。经典的皮亚杰数量、体积和质量守恒实验被深入分析，同时也评价了批判性研究，如 McGarrigle 和 Donaldson 的“顽皮小熊”实验，表明在儿童友好的条件下年幼儿童也能完成守恒。
The role of education and culture is considered through Vygotsky's theory of social development, highlighting the zone of proximal development and scaffolding. Students compare how social interaction, as opposed to innate maturation, influences cognitive growth.
教育与文化的作用通过维果茨基的社会发展理论加以探讨，重点介绍最近发展区和支架作用。学生比较社会互动（而非先天成熟）如何影响认知成长。
Research by Hughes on the 'policeman doll' task provided an alternative test of egocentrism, challenging some of Piaget's conclusions and demonstrating that task context can drastically alter a child's performance.
Hughes 的“警察玩偶”任务为自我中心主义提供了另一种测试，挑战了皮亚杰的某些结论，表明任务情境可显著改变儿童的表现。
6. Topic D: Social Influence – Conformity, Obedience, and Prosocial Behaviour | 主题 D：社会影响——从众、服从与亲社会行为
Social influence examines how individuals are affected by others. Conformity is studied through Asch's line judgment experiments, which revealed that many people conform to an obviously incorrect majority due to normative or informational influence.
社会影响探究个体如何受他人影响。通过阿希的线条判断实验学习从众行为，实验显示许多人会因规范影响或信息影响而从众于明显错误的大多数。
Obedience is explored using Milgram's electric shock experiment, which dramatically demonstrated that ordinary people are capable of inflicting harm when ordered by an authority figure. Ethical and situational explanations for obedience are key learning points.
服从行为通过米尔格拉姆的电击实验加以探讨，该实验惊人地表明普通人在权威指令下可能施加伤害。对服从的伦理和情境解释是关键学习内容。
Prosocial behaviour is covered through studies like Piliavin's subway experiment, which investigated helping behaviour in public settings. The bystander effect, diffusion of responsibility, and cost-reward models are used to explain why people do or do not help.
亲社会行为通过 Piliavin 的地铁实验等研究来探讨，该实验研究了公共场所的帮助行为。旁观者效应、责任分散和成本-奖赏模型被用来解释人们为何出手或不出手相助。
Students must be able to describe and evaluate these classic studies, considering factors such as sample size, ecological validity, and cultural bias, and discuss how the findings apply to real-world issues like bullying or emergency responses.
学生需能描述并评价这些经典研究，考虑样本量、生态效度和文化偏见等因素，并讨论研究结果如何应用于欺凌或应急响应等现实问题。
7. Topic E: Biopsychology – Brain, Neurons, and Neuropsychology | 主题 E：生物心理学——大脑、神经元与神经心理学
Biopsychology introduces the biological structures that underpin behaviour. The nervous system is outlined, distinguishing between the central nervous system (brain and spinal cord) and the peripheral nervous system.
生物心理学介绍支撑行为的生物结构。概述了神经系统，区分中枢神经系统（脑和脊髓）与外周神经系统。
Neurons and synaptic transmission are fundamental. Students learn how neurotransmitters like serotonin and dopamine relay signals across synapses, and how imbalances can be linked to psychological conditions such as depression or addiction.
神经元与突触传递是基础内容。学生将学习血清素和多巴胺等神经递质如何在突触间传递信号，以及递质失衡如何与抑郁或成瘾等心理状况相关。
Brain structure and localisation of function are studied using evidence from case studies like Phineas Gage, who survived an iron rod through his frontal lobe and showed profound personality changes. This supports the link between specific brain areas and behaviour.
通过学习 Phineas Gage 等案例研究来了解脑结构与功能定位，Gage 被铁棒穿过额叶后幸存并表现出明显人格变化，这支持了特定脑区与行为的关联。
Sperry's split-brain research provides further evidence of lateralisation, revealing how the left and right hemispheres process information independently. The use of techniques like CT and PET scans is discussed to show modern methods of investigating the brain.
Sperry 的裂脑研究为大脑偏侧化提供了更多证据，揭示了左右半球如何独立处理信息。CT 和 PET 扫描等技术被讨论，以展示现代大脑研究方法。
8. Research Methods in Psychology | 心理学研究方法
Research methods are woven throughout the syllabus, but students need explicit knowledge of experimental design (independent groups, repeated measures, matched pairs), variables (IV, DV, extraneous), and hypothesis writing.
研究方法贯穿整个大纲，但学生需要明确掌握实验设计（独立组、重复测量、配对组）、变量（自变量、因变量、额外变量）和假设的撰写。
Different types of experiments – laboratory, field, and natural – are compared for strengths and limitations. Non-experimental methods such as observations, questionnaires, interviews, and correlations also feature prominently.
不同类型的实验——实验室实验、现场实验和自然实验——的比较包括各自的优势与局限。观察、问卷、访谈及相关性研究等非实验方法也是重要内容。
Sampling techniques are essential: random, opportunity, volunteer, and stratified samples each have implications for representativeness and generalisability. Students must practise calculating measures of central tendency (mean, median, mode) and dispersion (range, standard deviation).
抽样技术至关重要：随机抽样、机会抽样、志愿者抽样和分层抽样各自对代表性和可推广性有不同影响。学生必须练习计算集中趋势量数（平均数、中位数、众数）和离散量数（极差、标准差）。
Data presentation includes bar charts, histograms, scatter graphs, and tables. Understanding how to interpret data and draw conclusions is tested explicitly in Paper 2, often through novel research scenarios.
数据呈现包括条形图、直方图、散点图和表格。试卷二明确考查对数据的解读和得出结论的能力，常通过新颖的研究情境出题。
9. Ethical Issues and Guidelines | 伦理问题与指导原则
Ethics is a cornerstone of psychological research. Students examine issues like informed consent, deception, protection from harm, privacy, and the right to withdraw, using the British Psychological Society (BPS) guidelines as a reference.
伦理是心理学研究的基石。学生以英国心理学会（BPS）指南为参考，探讨知情同意、欺骗、免受伤害、隐私和退出权利等议题。
Classic studies often pose ethical dilemmas: Milgram's participants were deceived and experienced extreme stress; Asch's participants were misled about the purpose of the study. These are used to debate the balance between scientific value and participant well-being.
经典研究常带来伦理困境：米尔格拉姆实验的参与者被欺骗并经历极端压力；阿希实验的参与者被误导了研究目的。这些案例被用来探讨科学价值与参与者福祉之间的平衡。
Ways to deal with ethical issues include presumptive consent, debriefing, and offering counselling. Candidates should be able to recommend improvements to ethically questionable procedures while respecting methodological rigour.
应对伦理问题的方式包括假定同意、事后解说和提供心理咨询。考生应能够在尊重方法严谨性的同时，针对有伦理争议的程序提出改进建议。
10. Key Studies Across the Syllabus | 贯穿大纲的关键研究
While each topic has its own core studies, some research is particularly significant and appears in multiple contexts. The table below summarises several must-know studies and their principal findings.
虽然每个主题都有其核心研究，但某些研究格外重要并出现在多个情境中。下表总结了一些必知研究及其主要发现。
| Study / Researcher | Key Finding (English) | 主要发现（中文） |
|---|---|---|
| Peterson & Peterson (1959) | Short-term memory lasts around 18–30 seconds without rehearsal. | 无复述时短时记忆持续约 18–30 秒。 |
| Bartlett (1932) | Memory is reconstructive and influenced by cultural schemas. | 记忆是重构性的，受文化图式影响。 |
| Asch (1951) | About 37% of responses conformed to an incorrect majority on a simple perceptual task. | 约 37% 的判断在简单知觉任务上从众于错误的大多数。 |
| Milgram (1963) | 65% of participants administered the maximum 450 V shock when ordered by an authority figure. | 65% 的参与者在权威指令下施加了最高 450 伏电击。 |
| Piliavin et al. (1969) | Help was more likely when the victim appeared ill rather than drunk; the 'cost-reward' model was supported. | 当求助者看似生病而非醉酒时，帮助更有可能发生；支持了“成本-奖赏”模型。 |
| Sperry (1968) | Split-brain patients could not verbally name objects presented to the left visual field, supporting hemispheric lateralisation. | 裂脑患者无法口头命名呈现在左视野的物体，支持了半球偏侧化。 |
| McGarrigle & Donaldson (1974) | Children could conserve number when the transformation appeared accidental ('naughty teddy'), challenging Piaget. | 当变化看似偶然（顽皮小熊）时，儿童能完成数量守恒，挑战了皮亚杰。 |
Memorising the author, year, aim, method, results, and conclusion of these studies is critical. Use flashcards and mind maps to link each study to the relevant topic and ethical point.
熟记这些研究的作者、年份、目的、方法、结果和结论至关重要。使用抽认卡和思维导图将每项研究与相关主题及伦理要点联系起来。
11. Effective Revision and Exam Techniques | 有效复习与考试技巧
Start revision early and break the syllabus into manageable chunks. Allocate specific days for each topic and interleave research methods practice. Active recall, such as self-quizzing without notes, strengthens memory far more than passive re-reading.
尽早开始复习，将大纲拆分成可管理的小块。为每个主题安排具体天数，并穿插研究方法练习。主动回忆法（如无笔记自我测验）比被动重读更能强化记忆。
For Paper 1, practise writing clear, structured answers using the PEEL technique (Point, Evidence, Explanation, Link). Always anchor your arguments to named studies and theory. For example, when explaining conformity, cite Asch and distinguish between normative and informational influence.
针对试卷一，练习使用 PEEL 结构（观点、证据、解释、联系）撰写清晰有条理的答案。始终将论点与指定研究和理论挂钩。例如解释从众时，引用阿希实验并区分规范影响和信息影响。
Paper 2 demands strong data analysis skills. Refresh your ability to calculate means, medians, and percentages. Practise interpreting graphs and tables by describing trends, anomalies, and what the data suggests. Be ready to identify flaws in a described study and propose ethical refinements.
试卷二要求扎实的数据分析技能。重新温习计算平均数、中位数和百分比的能力。练习解读图表与表格，描述趋势、异常值以及数据所表明的信息。做好准备指出所描述研究的缺陷并提出伦理改进措施。
Time management is vital: allocate roughly one minute per mark. Read source material carefully, highlight keywords, and plan longer responses briefly. Avoid writing generic introductions; instead, dive into the specific scientific content demanded by the question.
时间管理至关重要：大致为每一分值分配一分钟。仔细阅读所给材料，标记关键词，简要规划较长回答。避免撰写泛泛的引言，而应直接深入题目所要求的科学内容。
