📚 Year 12 OCR Psychology: Core Knowledge Summary | Year 12 OCR 心理学：核心知识点梳理
Mastering Year 12 OCR Psychology requires a clear understanding of the assessment structure, research methods, key perspectives, and all ten core studies across five areas. This article distils the essential knowledge you need, pairing each English explanation with its Chinese equivalent to support bilingual learners and ensure no concept is left behind.
掌握 Year 12 OCR 心理学需要清晰地理解评估结构、研究方法、关键视角以及覆盖五大领域的十项核心研究。本文提炼了你所必需的核心知识，每条英文讲解都配有对应的中文阐释，以支持双语学习者，确保不遗漏任何概念。
1. Course Structure and Assessment Overview | 课程结构与考试概览
The AS Level in Psychology (H167) consists of two examined components. Component 1 (Research Methods, 50%) assesses planning, conducting, analysing and evaluating psychological research. Component 2 (Core Studies, 50%) tests your knowledge and understanding of ten classic and contemporary studies, as well as the areas, perspectives and debates that frame them.
AS 心理学（H167）包含两个考试部分。第一部分（研究方法，占 50%）考查心理研究的计划、实施、分析和评价。第二部分（核心研究，占 50%）测试你对十项经典与当代研究的了解与理解，以及支撑这些研究的领域、视角和辩论。
Both papers feature multiple-choice questions, short-answer items and extended writing. Effective revision must interweave methodological skills with detailed knowledge of each core study, its background, procedure, findings and conclusions.
两份试卷都有选择题、简答题和论述题。有效的复习必须将方法论技能与每项核心研究的背景、步骤、结果和结论的详细知识交织在一起。
2. Research Methods and Design | 研究方法与设计
Aims and hypotheses form the starting point of any investigation. An aim is a general statement of intent, while a hypothesis is a precise, testable prediction. You must be able to formulate directional (one-tailed) and non-directional (two-tailed) hypotheses and identify independent (IV) and dependent (DV) variables.
目标和假设是任何研究的起点。目标是一个概括性的意图陈述，而假设是一个精确的、可检验的预测。你必须能够提出方向性（单尾）和非方向性（双尾）假设，并识别自变量（IV）和因变量（DV）。
Experimental designs – independent groups, repeated measures and matched pairs – each carry strengths and weaknesses in terms of participant variables and order effects. Understand how counterbalancing, random allocation and other controls can minimise extraneous variables, ensuring that changes in the DV are due to the IV rather than confounding variables.
实验设计——独立组、重复测量和配对组——在参与者变量和顺序效应方面各有优缺点。要理解平衡法、随机分配等控制手段如何最大程度减少额外变量，确保因变量的变化是由自变量而不是混淆变量引起的。
Non-experimental methods such as observation, self-report (questionnaires and interviews) and correlations appear frequently. You must know how to evaluate them in terms of reliability, validity, objectivity and representativeness, and be able to design your own simple piece of research.
观察法、自我报告法（问卷与访谈）以及相关研究等非实验方法也经常出现。你必须懂得如何从信度、效度、客观性和代表性的角度对它们进行评价，并能自己设计一项简单的研究。
3. Data Analysis and Descriptive Statistics | 数据分析与描述统计
Data handling covers levels of measurement (nominal, ordinal, interval), measures of central tendency (mean, median, mode) and measures of dispersion (range, variance, standard deviation). Knowing when to use each measure – for example, that the median is preferable for skewed ordinal data – is a core skill.
数据处理涵盖测量水平（定类、定序、定距）、集中趋势的度量（均值、中位数、众数）和离散程度的度量（极差、方差、标准差）。知道何时使用每种度量——例如，对于偏态的定序数据，中位数更为可取——是一项核心技能。
You are not required to calculate inferential statistics in AS, but you must interpret p-values and understand the concept of significance. A result is statistically significant if p ≤ 0.05, meaning there is a less than 5 % probability that the observed effect occurred by chance.
在 AS 阶段，你不需要计算推论统计，但必须解释 p 值并理解显著性的概念。若 p ≤ 0.05，结果就具有统计显著性，意味着观察到的效应偶然发生的概率低于 5 %。
Graphical representation, including bar charts, histograms and scattergrams, must be drawn and interpreted accurately. Pay close attention to labelling axes and identifying positive, negative or zero correlations.
图形呈现，包括条形图、直方图和散点图，必须准确绘制并解释。要特别注意标注坐标轴，并识别正相关、负相关或零相关。
4. Ethical Guidelines and Issues | 伦理准则与议题
The British Psychological Society (BPS) Code of Ethics centres on respect, competence, responsibility and integrity. Specific principles include informed consent, right to withdraw, deception, debriefing, confidentiality and protection from physical and psychological harm.
英国心理学会（BPS）伦理守则以尊重、胜任力、责任和诚信为核心。具体原则包括知情同意、退出权、欺骗、事后说明、保密以及对身心伤害的防护。
When evaluating core studies, you must be able to identify ethical strengths and weaknesses. For instance, Milgram’s research raised severe concerns about deception and protection from harm, while Bocchiaro’s study highlighted the tension between informed consent and the validity of obedience research.
评价核心研究时，你必须能识别伦理上的优劣势。例如，米尔格拉姆的研究在欺骗和免受伤害方面引发了严重关切，而博基亚罗的研究则凸显了知情同意与服从研究效度之间的张力。
Cost-benefit analysis is often applied: did the scientific gain outweigh the ethical costs? Keep this balanced reasoning ready for any extended response.
成本-收益分析常被运用：科学收获是否超过了伦理代价？请随时准备好这种平衡的推理，以应对任何论述题。
5. Areas of Psychology | 心理学领域
The five areas – social, cognitive, developmental, biological and individual differences – organise the ten core studies. Each area is defined by its assumptions, typical research methods and key themes.
五大领域——社会、认知、发展、生物和个体差异——组织了十项核心研究。每个领域由其假设、典型研究方法和关键主题来界定。
The social area assumes that behaviour is influenced by the actual, imagined or implied presence of others. Studies in this area often use controlled laboratory experiments to investigate obedience, conformity and whistle-blowing.
社会领域假设行为受到他人实际、想象或暗示的存在的影响。该领域的研究常采用可控实验室实验来调查服从、从众和举报行为。
The cognitive area focuses on internal mental processes such as memory, attention and perception. It often employs laboratory experiments and seeks to develop explanatory models of how information is processed.
认知领域关注记忆、注意、知觉等内部心理过程。它通常采用实验室实验，并试图建立解释信息如何处理的理论模型。
The developmental area examines how individuals change and remain stable across the lifespan. Research often uses longitudinal snapshots or cross-sectional comparisons, and Bandura’s study exemplifies the use of controlled observation with children.
发展领域考察个体在毕生发展过程中如何变化并保持稳定。研究常采用纵向快照或横断比较，班杜拉的研究是对儿童进行控制性观察的范例。
The biological area emphasises physiological, genetic and neural underpinnings of behaviour. Techniques range from split-brain studies to fMRI scans, assuming that behaviour has a biological origin.
生物领域强调行为的生理、遗传和神经基础。研究技术从裂脑研究到功能性磁共振成像不等，其假设是行为有生物学根源。
The individual differences area assumes that behaviour can be understood by focusing on what makes people distinct. It often uses case studies or clinical interviews to examine disorders like phobia, autism or unconscious conflict.
个体差异领域假设通过关注使人独特的因素可以理解行为。它常使用个案研究或临床访谈来考察恐怖症、自闭症或无意识冲突等障碍。
6. Psychological Perspectives | 心理学视角
Whereas areas demarcate topics, perspectives represent different theoretical lenses. The behaviourist perspective explains behaviour through stimulus-response associations and reinforcement, often dismissing internal mental states.
领域划分的是主题，而视角则代表不同的理论透镜。行为主义视角通过刺激-反应联结和强化来解释行为，常常忽略内部心理状态。
The psychodynamic perspective, originating with Freud, stresses unconscious motives, childhood experiences and psychic determinism. The cognitive perspective compares the mind to a computer, focusing on encoding, storage and retrieval.
源于弗洛伊德的心理动力学视角强调无意识动机、童年经历和心理决定论。认知视角将心智比作计算机，关注编码、存储和提取。
The biological perspective explains behaviour in terms of brain structures, neurotransmitters and genetic inheritance. For each core study, you should be able to identify which perspective(s) it aligns with and why.
生物视角从脑结构、神经递质和遗传的角度解释行为。对于每项核心研究，你应能说出它符合哪种（些）视角，并说明理由。
7. Key Debates | 关键辩论
Debates recur across the specification. Nature versus nurture asks whether behaviour is determined by genes or environment. In AS, both classic and contemporary studies often illustrate an interactionist stance, as in Casey’s work on delay of gratification, which acknowledges genetic neural bases and environmental shaping.
辩论在考纲中反复出现。天性-教养之争追问行为是由基因还是环境决定。在 AS 中，经典与当代研究常常展示互动论立场，例如凯西关于延迟满足的研究既承认基因神经基础，也承认环境塑造。
Free will versus determinism, reductionism versus holism, and nomothetic versus idiographic approaches are other essential debates. Be prepared to discuss how a study like Freud’s Little Hans represents an idiographic, psychodynamic and determinist position.
自由意志与决定论、还原论与整体论、律则式研究与特则式研究是另外的必学辩论。准备好讨论弗洛伊德的小汉斯研究如何体现特则式、心理动力学和决定论的立场。
Socially sensitive research and ethnocentrism also appear. Baron-Cohen’s Eyes Task can be criticised for overgeneralising and for using only European-Caucasian eye images, a point directly relevant to cultural bias.
社会敏感性研究和种族中心主义也会出现。巴伦-科恩的眼部任务可因过度概括和仅使用欧洲白人眼部图像而受批评，这一点直接关乎文化偏见。
8. Classic Core Studies: Social Area | 经典核心研究：社会领域
Milgram (1963) ‘Behavioural study of obedience’ used a controlled laboratory procedure in which participants believed they were administering increasingly severe electric shocks to a learner. Voltage rose to 450 V, and 65 % of participants continued to the maximum level. Milgram concluded that situational factors, such as the presence of an authority figure, can override moral conscience.
米尔格拉姆（1963）的’服从行为研究’采用控制性实验室程序，使参与者相信自己正在对一名学习者施加逐级增强的电击。电压升至 450 伏特，65 % 的参与者持续到了最高水平。米尔格拉姆得出结论：情境因素，如权威人物的在场，可以压倒道德良知。
Bocchiaro et al. (2012) ‘Disobedience and whistleblowing’ similarly investigated responses to unethical requests. Participants were tempted by an experimenter to write a fraudulent statement, and only a minority openly refused or blew the whistle. The study shows a gap between predicted courage and actual obedience.
博基亚罗等人（2012）的’不服从与举报’类似地考察了对不道德要求的反应。参与者被实验者诱惑写一份欺诈声明，只有少数人公开拒绝或举报。该研究显示了预测的勇气与实际服从之间的差距。
Both studies illuminate the power of social pressure, but Bocchiaro improved ethics by including a thorough debriefing and by avoiding the extreme distress seen in Milgram’s procedure.
两项研究都揭示了社会压力的力量，但博基亚罗通过彻底的事后说明和避免米尔格拉姆程序中出现的极端痛苦，改进了伦理。
9. Classic Core Studies: Cognitive Area | 经典核心研究：认知领域
Loftus and Palmer (1974) ‘Reconstruction of automobile destruction’ demonstrated that post-event information can distort memory. In Experiment 1, the verb used in a question (‘smashed’ versus ‘hit’) influenced speed estimates. In Experiment 2, the ‘smashed’ group was more likely to falsely report seeing broken glass a week later.
洛夫特斯与帕尔默（1974）的’汽车损毁的重构’证明，事后信息可以扭曲记忆。在实验 1 中，问题中使用的动词（’撞毁’相对于’碰撞’）影响了速度估计。在实验 2 中，’撞毁’组一周后更可能错误地报告看到了碎玻璃。
Grant et al. (1998) ‘Context-dependent memory’ showed that recall is superior when the encoding and retrieval environments match. Participants studied material in either silence or noise and were tested under matching or mismatching conditions. Performance was significantly higher in matching conditions, supporting the encoding-specificity principle.
格兰特等人（1998）的’情境依赖记忆’表明，当编码与提取环境匹配时，回忆效果更佳。参与者在安静或噪音中学习材料，并在匹配或不匹配的条件下接受测试。匹配条件下的成绩显著更高，支持编码特异性原则。
These cognitive studies illustrate how internal processes can be investigated rigorously, and they underpin applications in eyewitness testimony and educational settings.
这些认知研究说明了如何严谨地研究内部过程，它们为目击证词和教育环境的应用奠定了基础。
10. Classic Core Studies: Developmental, Biological and Individual Differences | 经典核心研究：发展、生物与个体差异
Bandura et al. (1961) ‘Transmission of aggression’ used a matched-participants design to show that children exposed to aggressive models reproduced significantly more verbal and physical aggression towards a Bobo doll. This classic study supports Social Learning Theory.
班杜拉等人（1961）的’攻击性传递’采用配对参与者设计，表明接触攻击性榜样的儿童对波波玩偶再现了显著更多的言语和身体攻击。这一经典研究支持社会学习理论。
Chaney et al. (2004) ‘Funhaler’ applied operant conditioning by fitting an inhaler with a whistle and a toy that spun when used correctly, improving compliance in asthmatic children. It demonstrates how behavioural principles can enhance health outcomes.
钱尼等人（2004）的’趣味吸入器’应用了操作条件作用，在吸入器上安装了哨子和正确使用时旋转的玩具，改善了哮喘儿童的依从性。这展示了行为原则如何提升健康效果。
Sperry (1968) ‘Split brain study’ examined patients whose corpus callosum had been severed. Results revealed hemispheric lateralisation: information presented to one visual field could be acted on but not spoken about if it only reached the non-verbal right hemisphere.
斯佩里（1968）的’裂脑研究’考察了胼胝体被切断的患者。结果揭示了半球功能偏侧化：呈现给一个视野的信息如果只到达非言语的右半球，就可以被操作但无法被言说。
Casey et al. (2011) ‘Neural correlates of delay of gratification’ followed individuals from Mischel’s original marshmallow test. Those with lower self-control as adults showed elevated activity in the ventral striatum and reduced prefrontal activity, linking brain function to the ability to resist temptation.
凯西等人（2011）的’延迟满足的神经相关’追踪了米歇尔原始棉花糖测试的个体。成年后自控力较低者表现出腹侧纹状体活动增强和前额叶活动减弱，将脑功能与抵抗诱惑的能力联系起来。
Freud (1909) ‘Little Hans’ case study analysed a five-year-old boy’s phobia of horses through psychoanalytic theory, interpreting it as displaced Oedipal anxiety. Despite its idiographic depth, the research lacks replicability and objectivity.
弗洛伊德（1909）的’小汉斯’个案研究通过精神分析理论分析了一个五岁男孩对马的恐惧，将其解释为移置的俄狄浦斯焦虑。尽管该研究具有特则式的深度，但缺乏可重复性和客观性。
Baron-Cohen et al. (1997) ‘Eyes Task’ tested adults with high-functioning autism, who were significantly worse at inferring mental states from eye photographs. This supports the theory of mind deficit and highlights individual differences in social cognition.
巴伦-科恩等人（1997）的’眼部任务’测试了高功能自闭症成人，他们在从眼部照片推断心理状态上显著更差。这支持了心理理论缺损，并凸显了社会认知中的个体差异。
These ten studies, spanning five areas and multiple perspectives, form the backbone of Year 12 OCR Psychology. Revisit them frequently, link each to methodology and ethics, and practise explaining how they illustrate the key debates.
这十项研究跨越五个领域和多种视角，构成了 Year 12 OCR 心理学的主干。要经常回顾它们，将每项研究与方法和伦理联系起来，并练习解释它们如何体现关键辩论。
