📚 IGCSE CCEA Psychology: International Competition Preparation Guide | IGCSE CCEA 心理学：国际竞赛备战攻略
Competitive psychology events reward more than memory. They test your ability to design studies, interpret data, evaluate evidence and apply CCEA-style concepts under time pressure. This guide breaks down a systematic preparation route from core content to exam-room strategy.
心理学竞赛不止考查记忆，更考查你设计研究、解读数据、评价证据以及在限时压力下运用 CCEA 风格概念的能力。本攻略将系统拆解从核心内容到考场策略的备考路径。
1. Know the Competition Format | 了解竞赛形式
Before revising, obtain the official syllabus or competition brief. Some contests use multiple-choice quizzes; others ask structured short answers, data-response questions and one extended experimental design task. Identify the mark allocation and timing to plan your revision priorities.
复习之前，先获取官方大纲或竞赛说明。有些竞赛使用选择题，有些则要求结构化简答、数据反应题和一道扩展实验设计任务。明确分值分配和时间限制，才能合理规划复习重点。
- Multiple-choice questions: test breadth of recall. | 选择题：考查知识广度。
- Short-answer questions: test definitions and applications. | 简答题：考查定义和应用。
- Data response: give a graph or table and ask for calculations. | 数据反应题：给出图表要求计算。
- Extended design task: write a full experimental plan. | 扩展设计题：撰写完整实验方案。
2. Master Research Methods | 掌握研究方法
Research methods form the backbone of nearly every competition paper. Be able to define and identify independent variables (IV), dependent variables (DV), extraneous variables and confounding variables. A strong operationalised hypothesis turns a vague aim into a testable statement.
研究方法是几乎所有竞赛试卷的主干。要能定义并识别自变量（IV）、因变量（DV）、额外变量和混淆变量。一个清晰的操作化假设能把模糊的研究目的变成可检验的陈述。
Learn three experimental designs. Independent groups use different participants in each condition; repeated measures use the same participants in all conditions; matched pairs pair participants on key traits before random assignment. Be ready to explain one strength and one limitation of each.
掌握三种实验设计。独立组设计在每个条件下使用不同被试；重复测量设计在所有条件下使用同一批被试；配对组设计先按关键特征配对再随机分配。要能说出每种设计的一个优点和一个局限。
3. Biological Psychology Essentials | 生物心理学核心
For biological psychology, focus on the structure and function of neurons, synaptic transmission and common neurotransmitters such as dopamine and serotonin. You may be asked to explain how an action potential triggers release of neurotransmitters into the synaptic gap.
在生物心理学部分，重点掌握神经元结构与功能、突触传递以及多巴胺、5-羟色胺等常见神经递质。你可能会被要求解释动作电位如何促使神经递质释放到突触间隙。
Also revise central nervous system and peripheral nervous system divisions, and brain imaging techniques like fMRI and PET. A common evaluation point is that biological explanations can be reductionist because they simplify complex behaviour to brain processes.
还要复习中枢神经系统和外周神经系统的划分，以及 fMRI、PET 等脑成像技术。常见的评价点是生物解释可能具有还原论倾向，因为它将复杂行为简化为大脑过程。
4. Cognitive Psychology | 认知心理学
Cognitive questions often test memory models. Know the multi-store model of memory: sensory register, short-term memory and long-term memory, with capacity, duration and coding. Also revise Baddeley’s working memory model and its components.
认知类题目常考查记忆模型。要掌握多贮存模型：感觉登记、短时记忆和长时记忆，以及它们的容量、持续时间和编码方式。还要复习巴德利的工作记忆模型及其成分。
Apply these models to scenarios such as why a student forgets a phone number or why chunking helps recall. Evaluation can focus on supporting evidence and the artificiality of laboratory experiments.
要会把这些模型应用到具体情境，例如为什么学生忘记电话号码，或者组块为什么有助于回忆。评价可以围绕支持证据以及实验室实验的生态效度展开。
5. Social Psychology & Group Behaviour | 社会心理学与群体行为
Social psychology competitions often use classic studies. Revise Asch’s conformity experiments, Milgram’s obedience research and the Stanford prison experiment. Know how group pressure, authority and role adoption influence behaviour.
社会心理学竞赛常引用经典研究。要复习阿希的从众实验、米尔格拉姆的服从研究和斯坦福监狱实验。掌握群体压力、权威和角色扮演如何影响行为。
Be prepared to evaluate these studies ethically and methodologically. For example, Milgram’s procedure raises serious ethical concerns about deception and psychological harm, but it also produced high internal validity through controlled conditions.
要能从伦理和方法两个角度评价这些研究。例如，米尔格拉姆的程序在欺骗和心理伤害方面存在严重伦理问题，但其严格控制的条件也带来了较高的内部效度。
6. Developmental Psychology | 发展心理学
In developmental psychology, revise attachment styles, separation anxiety and the strange situation procedure. Also compare Piaget’s stage theory with Vygotsky’s emphasis on social interaction and scaffolding.
在发展心理学部分，复习依恋类型、分离焦虑和陌生情境程序。还要比较皮亚杰的阶段理论与维果茨基对社会互动和支架作用的强调。
Competition questions may present a child behaviour case study and ask you to identify the likely stage or attachment type. Use precise terms such as object permanence, conservation, or zone of proximal development.
竞赛题目可能给出儿童行为案例，要求你判断所处的认知阶段或依恋类型。要使用准确术语，如客体永久性、守恒或最近发展区。
7. Individual Differences & Mental Health | 个体差异与心理健康
Individual differences covers intelligence, personality, gender and cultural variation. Know the difference between fixed and growth mindsets, and how labelling or stigma can affect mental health and help-seeking behaviour.
个体差异部分包括智力、人格、性别和文化差异。要了解固定型思维与成长型思维的区别，以及标签和污名如何影响心理健康和求助行为。
Understand definitions of normality and abnormality, including statistical infrequency, deviation from social norms and failure to function adequately. These definitions are evaluation-rich, so practise applying and criticising them.
理解正常与异常的几种定义，包括统计稀有性、偏离社会规范以及功能失调。这些定义很适合出评价题，要练习应用和批判。
8. Experimental Design & Ethics | 实验设计与伦理
Many contests reward a clear experimental design more than any single fact. Practise writing an aim, an alternative or null hypothesis, and a fully operationalised IV and DV. State whether you would use independent groups, repeated measures or matched pairs, and justify your choice.
许多竞赛对清晰实验设计的加分超过任何单一知识点。练习撰写研究目的、备择或零假设，以及完全操作化的自变量和因变量。说明你使用独立组、重复测量还是配对组设计，并说明理由。
Ethical issues must be explicit. Address informed consent, right to withdraw, confidentiality, deception, debriefing and protection from harm. If a study involves children, explain how you would obtain parental consent and child assent.
伦理问题必须明确写出。要处理知情同意、退出权、保密、欺骗、事后解释和免受伤害。如果研究涉及儿童，要说明如何获得家长同意和儿童同意。
9. Data Analysis & Statistics | 数据分析与统计
Descriptive statistics are common in data-response questions. Calculate the mean, median, mode and range, and choose the most appropriate measure of central tendency for skewed data. Use percentages to compare conditions when sample sizes differ.
描述统计常出现在数据反应题中。会计算平均数、中位数、众数和全距，并且能针对偏态数据选择最合适的集中量数。样本量不同时，用百分比进行比较。
Mean = Σx ÷ N Range = Highest value − Lowest value
Interpret graphs and correlation coefficients. State clearly that correlation does not imply causation because a third variable may explain the relationship.
会解读图表和相关系数。要明确指出相关不等于因果，因为可能存在第三个变量解释两者关系。
10. Essay and Short-Answer Technique | 论文与简答题技巧
Use command words to shape your answer. ‘Describe’ asks for accurate detail; ‘explain’ asks for a mechanism or reason; ‘evaluate’ asks for strengths, weaknesses and a judgement. A useful structure is Point, Evidence, Explain, and Link back to the question.
根据指令词来确定答题结构。’描述’要求准确细节，’解释’要求机制或原因，’评价’要求优点、缺点和判断。一个实用结构是观点、证据、解释和回扣题目（PEEL）。
For extended writing, spend 3-5 minutes planning. Write one paragraph per point, keep evaluation balanced, and end with a short conclusion. Under time pressure, clarity beats quantity.
扩展写作要花 3 到 5 分钟列提纲。每个论点写一段，评价要均衡，最后写简短结论。限时压力下，清晰比数量更重要。
11. Revision Timetable & Active Recall | 复习计划与主动回忆
Replace passive re-reading with active recall. After studying a topic, close your notes and write or say everything you remember. Use flashcards with questions on one side and answers on the other, and interleave topics rather than blocking.
用主动回忆代替被动重读。学完一个主题后，合上笔记，默写或口述你记得的所有内容。使用一面问题、一面答案的闪卡，并采用交错复习而不是集中复习。
Plan a weekly timetable that cycles through research methods, biological, cognitive, social, developmental and individual differences. Add one timed past paper or competition simulation each Saturday and analyse your errors.
制定周计划，循环复习研究方法、生物、认知、社会、发展和个体差异。每周六做一次限时真题或竞赛模拟，并分析错误。
12. Mock Competition and Final Review | 模拟竞赛与最后复习
In the final two weeks, run full mock papers under strict time limits. Mark them using the mark scheme, then record which topics lose the most marks. Revisit those topics with targeted tasks and one-page summaries.
最后两周，严格按照时间限制做整套模拟卷。按评分标准批改，记录哪些主题失分最多。再用针对任务和一页纸总结重新复习这些主题。
Prepare your body and mind: maintain sleep, eat before the competition, and use slow breathing if you feel anxious. Arrive with a clear plan for each section and a time allowance.
做好身心准备：保持睡眠，赛前进食，紧张时用慢呼吸调节。到达考场时对每个部分都有清晰计划和时间分配。
