Paper 1: Foundations in Psychology 心理学基础

Paper 1 (9PS0/01, 2 hours, 90 marks, 35% of A-Level) covers four major approaches: Social Psychology, Cognitive Psychology, Biological Psychology, and Learning Theories. Each approach is assessed through short-answer questions (2-6 marks) and extended essays (8-16 marks). You must know at least two studies per approach, including methodology, results, and evaluation. Paper 1 (9PS0/01, 2 小时, 90 分, 占 A-Level 总分的 35%) 涵盖四大理论流派：社会心理学、认知心理学、生物心理学和学习理论。每个流派均通过简答题 (2-6 分) 和扩展论述题 (8-16 分) 考查，需要掌握至少两项经典研究，包括方法、结果和评价。

Social Psychology 社会心理学
Key studies: Milgram (1963) obedience, Sherif (1954) Robbers Cave. Essay focus: Agency Theory vs Social Impact Theory. Individual differences in obedience and prejudice. 关键研究：Milgram 服从实验 (1963), Sherif 盗贼洞实验 (1954)。论述重点：代理理论 vs 社会影响理论，服从与偏见的个体差异。 Cognitive Psychology 认知心理学
Key studies: Baddeley (1966b) STM encoding, Bartlett (1932) reconstructive memory. Essay focus: Multi-Store Model vs Working Memory Model. Schema theory and reconstructive memory evaluation. 关键研究：Baddeley 短时记忆编码 (1966b), Bartlett 重建记忆 (1932)。论述重点：多储存模型 vs 工作记忆模型，图式理论评价。 Biological Psychology 生物心理学
Key studies: Raine et al. (1997) brain imaging, Brendgen et al. (2005) twin aggression. Essay focus: brain structure and aggression, neurotransmitter roles (serotonin, dopamine). Hormones and evolutionary explanations. 关键研究：Raine 脑成像研究 (1997), Brendgen 双胞胎攻击行为 (2005)。论述重点：脑结构与攻击行为，神经递质 (血清素、多巴胺) 的作用。 Learning Theories 学习理论
Key studies: Watson & Rayner (1920) Little Albert, Bandura (1961) Bobo doll. Essay focus: Classical Conditioning vs Operant Conditioning. Social Learning Theory (attention, retention, reproduction, motivation). 关键研究：Watson & Rayner 小阿尔伯特 (1920), Bandura 波波玩偶 (1961)。论述重点：经典条件反射 vs 操作性条件反射，社会学习理论的四阶段。

Paper 2: Applications of Psychology 心理学应用

Paper 2 (9PS0/02, 2 hours, 90 marks, 35%) includes Clinical Psychology (compulsory) and one optional application. Most centres teach Criminological Psychology as the option. Clinical Psychology covers classification systems (DSM-5, ICD-11), schizophrenia and one other disorder (e.g., anorexia nervosa), plus treatment approaches. Criminological Psychology covers explanations of crime, jury decision-making, eyewitness testimony, and offender treatment. Paper 2 (35%) 包含临床心理学 (必修) 和一门选修应用。多数学校选择犯罪心理学。临床心理学涵盖诊断系统 (DSM-5, ICD-11)、精神分裂症与另一种障碍 (如厌食症) 及治疗方法。犯罪心理学涵盖犯罪解释、陪审团决策、目击证词和罪犯治疗。

The Clinical Psychology essay requires you to evaluate at least two explanations and two treatments for a disorder, referencing studies with dates. Edexcel rewards breadth of evidence: name at least four researchers per disorder. For Criminological Psychology, the key essays are on social explanations of crime (labelling theory, social learning theory) versus biological explanations (genetics, brain structure), and on factors affecting eyewitness testimony (weapon focus, leading questions, anxiety). 临床心理学论述题要求评价至少两种障碍解释和两种治疗方法，引用带年份的研究。Edexcel 奖励证据广度：每种障碍至少引用四位研究者。犯罪心理学的核心论述题是社会解释 (标签理论、社会学习理论) vs 生物解释 (遗传、脑结构)，以及目击证词的影响因素 (武器焦点、诱导性问题、焦虑)。

Paper 3: Psychological Skills 心理学研究技能

Paper 3 (9PS0/03, 2 hours, 80 marks, 30%) is the most technically demanding paper. It covers Research Methods (methods, design, sampling, ethics, data analysis), statistical tests (sign test, chi-squared, Mann-Whitney, Wilcoxon, Spearman, unrelated/related t-test, Pearson), and Issues & Debates (nature/nurture, free will/determinism, reductionism/holism, ethics, socially sensitive research, cultural bias). Unlike AQA, Edexcel Paper 3 integrates research methods questions directly into the Issues & Debates section rather than having a standalone methods paper. 试卷三 (30%) 是技术要求最高的试卷，涵盖研究方法 (实验设计、抽样、伦理、数据分析)、统计检验 (符号检验、卡方、Mann-Whitney、Wilcoxon、Spearman、相关/独立 t 检验、Pearson) 以及议题与争议 (先天/后天、自由意志/决定论、还原论/整体论、伦理、社会敏感研究、文化偏见)。与 AQA 不同，Edexcel 试卷三将研究方法问题直接融入议题与争议部分。

Statistical analysis is worth approximately 20 marks across the paper. You must be able to identify the correct statistical test from a scenario, calculate it (formulas are provided for parametric tests but not for non-parametric observed values), interpret the critical value table, and write a conclusion linking to the research hypothesis. Issues & Debates essays are 20-mark extended responses requiring synoptic awareness: you must draw on content from Papers 1 and 2 to support arguments. 统计分析约占 20 分。你必须能够从场景中识别正确的统计检验、进行计算 (参数检验公式会提供，非参数检验的观察值计算需自己完成)、解读临界值表，并撰写与假设相关联的结论。议题与争议的 20 分扩展论述要求综合意识：必须引用试卷一和试卷二的内容来支撑论点。

Research Methods: What Examiners Want 研究方法评分要点

Edexcel Psychology places heavier weight on practical research skills than AQA. 26% of all A-Level marks come from research methods content, distributed across all three papers. The four key question types are: (1) Designing a study: given a scenario, describe the IV, DV, experimental design (independent groups, repeated measures, matched pairs), sampling method, ethical considerations, and procedure. This is typically a 12-mark question. (2) Data analysis: calculate measures of central tendency and dispersion, draw and interpret graphs (bar charts, histograms, scattergrams), and identify skew. (3) Inferential statistics: choose the correct test, state the hypothesis (directional/non-directional), calculate the observed value, compare to the critical value, and write a conclusion. (4) Methodological evaluation: discuss the strengths and weaknesses of a described study in terms of validity, reliability, generalisability, and ethics. Edexcel 心理学对实用研究技能的重视度高于 AQA。26% 的 A-Level 总分来自研究方法内容，分布在三份试卷中。四类关键题型：(1) 设计研究 (12 分)；(2) 数据分析 (集中量数和离散量数)；(3) 推断统计 (选择检验、计算、对比临界值、结论)；(4) 方法论评价 (效度、信度、推广性、伦理)。

Exam Technique: Edexcel Psychology Mark Schemes 考试技巧

Edexcel uses a specific command-word hierarchy that determines how you structure answers. "Identify" / "State" (1-2 marks): give the answer, no elaboration needed. "Describe" (4 marks): detailed account of a study or theory, covering aim, procedure, findings, and conclusion. "Explain" (4-6 marks): give reasons why something happens, applying theory to context. "Evaluate" / "Discuss" (8-20 marks): balance strengths and limitations, use evidence to support each point, and always include a concluding judgment. Edexcel 使用特定的指令词层级来决定答案结构。"Identify" / "State" (1-2 分)：给出答案，无需展开。"Describe" (4 分)：详细描述研究或理论，涵盖目的、过程、发现和结论。"Explain" (4-6 分)：解释原因，将理论应用于情境。"Evaluate" / "Discuss" (8-20 分)：平衡优势与局限性，用证据支撑每个观点，并始终包含结论性判断。

The AO1/AO2/AO3 mark split is critical. For an 8-mark essay, 4 marks are AO1 (knowledge and understanding: describe the theory or study) and 4 marks are AO3 (evaluation: strengths and weaknesses with evidence). For a 16-mark essay, 6 marks AO1 and 10 marks AO3. Edexcel rewards application (AO2) in Paper 2 scenarios: always link theory back to the stem material using phrases like "This can be explained by..." or "As demonstrated in the scenario...". AO1/AO2/AO3 分数分配至关重要。8 分论述题：4 分 AO1 (描述理论或研究)，4 分 AO3 (评价优缺点)。16 分论述题：6 分 AO1，10 分 AO3。Edexcel 在试卷二的场景题中奖励应用能力 (AO2)：始终将理论链接回题干材料。

Top 5 Mistakes Edexcel Psychology Students Make 五大常见错误

1. Not naming researchers with dates 不标注研究者年份: Edexcel mark schemes explicitly credit named researchers with year of publication (e.g., "Baddeley (1966b) found that..."). Writing "a study showed..." without attribution loses AO1 marks. Edexcel 评分标准明确奖励标注研究者姓名和年份的引用。笼统写 "一项研究表明..." 会丢失 AO1 分数。 2. Writing one-sided evaluation 片面评价: A common error is listing only strengths or only limitations. Edexcel expects balanced evaluation with a concluding paragraph that weighs the evidence. 常见错误是只列优点或只列缺点。Edexcel 期望平衡的评价，并在结论段中权衡证据。 3. Confusing statistical tests 混淆统计检验: Students often mix up Mann-Whitney (unrelated design, ordinal data) with Wilcoxon (related design, ordinal data). Create a decision flowchart: start with the experimental design, then the level of measurement, then choose the test. 学生常混淆 Mann-Whitney (独立设计、顺序数据) 和 Wilcoxon (相关设计、顺序数据)。建立决策流程图：先判断实验设计，再判断测量水平，最后选择检验。 4. Skipping the concluding judgment 缺少总结性判断: For 16-mark essays, the final 2-3 marks are reserved for a conclusion that answers the question (e.g., "Overall, biological explanations provide the strongest account because..."). 16 分论述题的最后 2-3 分专属于回答问题的总结性判断。直接停笔不写总结等于主动放弃分数。 5. Using generic evaluation points 使用通用评价: Writing "this study lacks ecological validity" without explaining why the specific task was artificial scores zero. Tie every evaluation point to the specific study: "Because participants were asked to memorize word lists in a laboratory, the findings may not reflect how memory works in everyday contexts like remembering a shopping list." 写 "缺乏生态效度" 而不解释具体任务为何不自然，得分为零。每个评价点必须紧扣具体研究。
