📚 Year 11 Edexcel Psychology: Core Knowledge Summary | Year 11 Edexcel 心理学核心知识点梳理
Year 11 of the Edexcel GCSE Psychology course focuses primarily on the topics assessed in Paper 2. This paper examines your understanding of social influence – how others affect our behaviour – and two optional topics chosen by your school from criminal psychology, the self, and sleep and dreaming. This revision guide pulls together the essential theories, key studies, and core terminology that frequently appear in exam questions. It is designed to help you consolidate knowledge and sharpen your application skills for the final assessments.
在 Edexcel GCSE 心理学课程的 Year 11 阶段，重点主要放在试卷二所考查的主题上。这份试卷评估你对社会影响（即他人如何影响我们的行为）的理解，以及学校从犯罪心理学、自我心理学和睡眠与做梦中选择的两个选修主题。本复习指南梳理了考试中经常出现的核心理论、关键研究和重要术语，旨在帮助你巩固知识，提升在最终考试中应用心理学概念的能力。
1. Paper 2 Overview and Assessment | 试卷二概览与评估
Paper 2 (1PS0/02) makes up 45% of the GCSE and lasts 1 hour 20 minutes. It contains three sections: Section A covers the compulsory Social Influence topic, while Sections B and C each assess one of the two optional topics your centre has selected. The question styles include multiple-choice, short-open response, and extended writing (up to 9 marks). You are expected to know a range of studies, apply your knowledge to novel scenarios, and evaluate strengths and weaknesses of theories and research.
试卷二 (1PS0/02) 占总成绩的 45%，考试时长为 1 小时 20 分钟。它包含三个部分：A 部分考查必修的“社会影响”主题，B 和 C 部分各自评估你所在学校选择的两个选修主题中的其中一个。题型包括选择题、简短开放式回答以及扩展写作（最高 9 分）。你应当熟悉一系列研究，能够将知识应用到新颖的情境中，并评价理论和研究的优缺点。
2. Social Influence: Conformity (Asch) | 社会影响：从众（阿希实验）
Solomon Asch (1951) demonstrated conformity by asking participants to match lines in the presence of confederates who deliberately gave wrong answers. In the original study, about 37% of the responses were conforming, and 75% of participants conformed at least once. Asch identified group size, unanimity, and task difficulty as key variables influencing conformity levels. The study highlights normative social influence – the desire to fit in with the group – as a powerful driver of behaviour.
所罗门·阿希 (1951) 通过让参与者在一群故意给出错误答案的同伴面前匹配线段，揭示了从众现象。在原始实验中，大约 37% 的回答是从众的，75% 的参与者至少从众过一次。阿希指出群体规模、一致性以及任务难度是影响从众程度的关键变量。这项研究突显了规范性社会影响——渴望与群体保持一致——作为行为的有力驱动因素。
3. Social Influence: Obedience (Milgram) | 社会影响：服从（米尔格拉姆实验）
Stanley Milgram (1963) investigated obedience by instructing participants to deliver increasingly strong electric shocks to a confederate ‘learner’. An alarming 65% of participants administered the maximum 450-volt shock. Factors such as proximity of the authority figure, legitimacy of the setting, and proximity of the victim significantly altered obedience rates. Milgram’s agency theory suggests that people shift to an ‘agentic state’, viewing themselves as instruments of authority, thereby diffusing personal responsibility.
斯坦利·米尔格拉姆 (1963) 通过指示参与者向扮演“学习者”的同伴施加越来越强的电击来研究服从。令人震惊的是，65% 的参与者施加了最高 450 伏的电击。权威人物的接近程度、环境的合法性以及受害者的接近程度等因素显著改变了服从率。米尔格拉姆的代理理论认为，人们会转入“代理状态”，将自己视作权威的工具，从而分散个人责任。
4. Social Influence: Bystander Intervention | 社会影响：旁观者干预
Latané and Darley (1968) proposed that the presence of others reduces the likelihood of helping due to diffusion of responsibility and pluralistic ignorance. Their seizure experiment found that when participants believed they were alone with a victim, 85% helped, compared to only 31% when they thought four other bystanders were present. The decision model of helping (notice, interpret, assume responsibility, decide how to help, provide help) explains the cognitive steps behind intervention or inaction.
拉坦内和达利 (1968) 提出，他人的存在会由于责任分散和多元无知效应而降低提供帮助的可能性。在他们的癫痫发作实验中，当参与者认为自己独自与受害者相处时，85% 的人提供了帮助，而认为还有其他四名旁观者在场时，只有 31% 的人会介入。助人决策模型（注意、理解、承担责任、决定如何帮助、实施帮助）解释了干预或不作为背后的认知步骤。
5. Social Influence: Crowd and Collective Behaviour | 社会影响：群体与集体行为
Zimbardo (1969) linked deindividuation – loss of self-awareness and individual identity within a crowd – to antisocial behaviours. Anonymity, arousal, and group size increase deindividuation. In contrast, Reicher’s social identity model argues that crowd behaviour is not mindless but reflects a shared social identity and group norms. This shift in perspective explains both orderly protests and destructive riots by focusing on the values of the group rather than a mere loss of self.
津巴多 (1969) 将去个体化——在群体中丧失自我意识和个体身份——与反社会行为联系起来。匿名性、唤醒水平和群体规模会增强去个体化。与此不同，瑞切尔的社會认同模型认为，群众行为并非无理智的，而是反映了共享的社会认同和群体规范。这一视角的转变通过聚焦于群体价值观而非单纯的自我丧失，解释了有序的抗议和破坏性的骚乱。
6. Criminal Psychology: Explanations of Crime | 犯罪心理学：犯罪解释
Social Learning Theory, as proposed by Bandura, explains offending through observation, modelling, and vicarious reinforcement. Eysenck’s Personality Theory, by contrast, attributes criminal tendencies to high extraversion, high neuroticism, and high psychoticism, rooted in biological differences in arousal levels. Heaven (1996) found self-reported delinquency correlated with these personality dimensions. Both theories have influenced treatment but are criticised for being reductionist and ignoring situational factors.
班杜拉的社会学习理论通过观察、模仿和替代强化来解释犯罪行为。而艾森克的人格理论则将犯罪倾向归因于高外向性、高神经质和高精神质，这些特质根植于唤醒水平的生理差异。希文 (1996) 发现自我报告的偏差行为与这些人格维度存在相关。二者都影响了治疗方法，但被批评过于简化且忽略了情境因素。
7. Criminal Psychology: Treatment and Punishment | 犯罪心理学：治疗与惩罚
Anger management programmes draw on cognitive-behavioural principles to help offenders recognise triggers, control arousal, and replace aggressive responses. Restorative justice shifts the focus from punishment to repairing harm, bringing offender and victim together to communicate. Research indicates that restorative justice can reduce reoffending rates by up to 14% in some studies (Sherman & Strang, 2007), although its effectiveness varies depending on crime type and willingness of participants.
愤怒管理项目借鉴认知行为原理，帮助罪犯识别触发因素、控制生理唤醒并替换攻击性反应。恢复性司法将重点从惩罚转向修复伤害，让犯罪者和受害者面对面交流。研究表明，在某些研究中恢复性司法可将再犯率降低高达 14%（舍曼和斯特朗，2007），尽管其有效性因犯罪类型和参与者的意愿而异。
8. Sleep and Dreaming: Stages and Functions | 睡眠与梦：阶段与功能
A full sleep cycle lasts roughly 90 minutes and repeats 4–5 times per night, comprising NREM stages 1–3 and REM sleep. The restoration theory (Oswald, 1980) suggests NREM sleep repairs the body via growth hormone release, while REM sleep restores the brain. The evolutionary theory (Webb, 1979) argues sleep evolved to conserve energy and keep animals safe during vulnerable periods. A key criticism is that the restoration theory cannot fully explain why REM sleep is so active.
一个完整的睡眠周期大约持续 90 分钟，每晚重复 4–5 次，包括非快速眼动睡眠阶段 1–3 和快速眼动睡眠。恢复理论（奥斯瓦尔德，1980）提出非快速眼动睡眠通过释放生长激素修复身体，而快速眼动睡眠则恢复大脑。进化理论（韦伯，1979）认为睡眠的进化是为了保存能量，并使动物在易受攻击的时段保持安全。一个关键批评是，恢复理论无法充分解释为何快速眼动睡眠如此活跃。
9. Sleep and Dreaming: Freudian Theory of Dreaming | 睡眠与梦：弗洛伊德梦的理论
Freud’s (1900) theory distinguishes between the manifest content – the actual storyline of a dream – and the latent content, its hidden unconscious wishes. He proposed that dreams serve as a ‘royal road to the unconscious’, acting as wish fulfilment and protecting sleep by disguising disturbing desires through dreamwork processes such as condensation and displacement. While hugely influential, this theory lacks empirical support, as dreams cannot be directly observed and interpretations rely heavily on the analyst’s subjectivity.
弗洛伊德 (1900) 的理论区分了显性内容——梦的实际情节——与隐性内容，即其隐藏的潜意识愿望。他提出梦是“通往潜意识的捷径”，起着愿望实现的作用，并通过凝缩和移置等梦的运作过程伪装令人不安的欲望，从而保护睡眠。尽管影响巨大，该理论缺乏实证支持，因为梦境无法直接观察，且解读严重依赖分析者的主观性。
10. Research Methods and Key Studies | 研究方法与关键研究
Across all topics, you must be confident with research methods including experiments (lab, field, and quasi), observations, correlations, and case studies. You need to identify independent and dependent variables, evaluate validity and reliability, and discuss ethical issues such as informed consent, deception, and protection from harm. For example, Milgram’s obedience study raised profound ethical concerns over psychological distress, while Asch’s conformity experiment involved deception about the purpose of the study.
在所有主题中，你必须熟练掌握研究方法，包括实验法（实验室、现场和准实验）、观察法、相关法以及个案研究。你需要能够识别自变量和因变量，评价效度和信度，并讨论知情同意、欺骗以及免受伤害等伦理问题。例如，米尔格拉姆的服从研究因其造成的心理痛苦而引发了深刻的伦理关切，而阿希的从众实验则涉及对研究目的的欺骗。
