欢迎阅读本篇 Pre-U OCR 心理学核心知识点梳理。本指南整合了你需要掌握的基本理论、核心研究和关键争论，系统呈现了 20 项核心研究、它们的方法学特点以及联结它们的广泛议题。无论你是在为试卷一、试卷二进行复习，还是在探索应用选项，这份资料都将巩固你对考纲关键内容的理解。
1. Core Studies Framework | 核心研究框架
The Pre-U OCR specification is built around 20 core studies spread across five psychological perspectives: cognitive, biological, social, developmental, and individual differences (the latter incorporating psychopathology). These studies are not only assessed individually but also form the basis for thematic comparisons in Paper 2, where questions explore areas such as methodology, ethics, culture, and debates like nature versus nurture.
Pre-U OCR 教学大纲围绕分布在五个心理学视角下的 20 项核心研究构建：认知、生物、社会、发展和个体差异（后者包括心理病理学）。这些研究不仅被单独评估，还构成试卷二主题比较的基础，试卷二的题目探讨方法学、伦理、文化以及先天与后天等争论。
Mastering the core studies involves knowing the background, aim, procedure, findings, and conclusions for each, as well as being able to evaluate their strengths and weaknesses. The six key themes — methodology, ethics, culture, nature-nurture, individual vs. situational explanations, and the use of children and animals in research — run through the entire course and are essential for high-level analysis.
掌握核心研究需要了解每一项研究的背景、目的、程序、结果和结论，并能评价其优缺点。六大关键主题——方法学、伦理、文化、先天与后天、个体解释与情境解释、以及儿童与动物在研究中的使用——贯穿整个课程，对高水平分析至关重要。
2. Cognitive Psychology | 认知心理学
The cognitive approach focuses on internal mental processes such as memory, attention, and perception. Core studies in this area include Loftus & Palmer (1974) on eyewitness testimony, Grant et al. (1998) on context-dependent memory, Moray (1959) on dichotic listening, and Simons & Chabris (1999) on inattentional blindness.
认知视角关注记忆、注意和知觉等内部心理过程。该领域的核心研究包括 Loftus 和 Palmer (1974) 关于目击者证词的研究、Grant 等人 (1998) 关于情境依赖记忆的研究、Moray (1959) 关于双耳分听的研究以及 Simons 和 Chabris (1999) 关于非注意盲视的研究。
Loftus and Palmer demonstrated how leading questions can alter memory for an event, with the verb ‘smashed’ producing higher speed estimates than ‘contacted’. This supports the reconstructive nature of memory. Grant et al. found that students who learned and were tested in matching environments (context-dependent memory) recalled significantly more material, highlighting the practical applications for exam revision.
Loftus 和 Palmer 展示了引导性问题如何改变对事件的记忆，动词 ‘smashed’ 比 ‘contacted’ 导致更高的车速估计，这支持了记忆的重构性。Grant 等人发现，在匹配环境中学习和测试的学生（情境依赖记忆）回忆的材料显著更多，突显了在考试复习中的实际应用。
Theoretical models are fundamental. The multi-store model proposes separate sensory, short-term, and long-term stores with attention and rehearsal as key processes. Baddeley’s working memory model replaces unitary STM with a central executive, phonological loop, visuospatial sketchpad, and episodic buffer, explaining how we process multiple pieces of information simultaneously.
理论模型是基础。多贮存模型提出独立的感觉、短期和长期贮存，注意和复述是关键过程。Baddeley 的工作记忆模型用中央执行器、语音回路、视空间画板和情景缓冲器取代了单一的短时记忆，解释了我们如何同时处理多条信息。
3. Biological Psychology | 生物心理学
The biological perspective explains behaviour through physiological processes. Key studies are Sperry (1968) on split-brain patients, Casey et al. (2011) on neural correlates of delay of gratification, Maguire et al. (2000) on hippocampal plasticity in taxi drivers, and Blakemore & Cooper (1970) on visual cortex development in cats.
生物视角通过生理过程解释行为。关键研究包括 Sperry (1968) 关于裂脑患者的研究、Casey 等人 (2011) 关于延迟满足的神经相关物的研究、Maguire 等人 (2000) 关于出租车司机海马体可塑性的研究以及 Blakemore 和 Cooper (1970) 关于猫视觉皮层发展的研究。
Sperry’s split-brain research revealed hemispheric lateralisation: the left hemisphere is primarily responsible for language production, while the right excels in spatial and visual-motor tasks. Maguire et al. used MRI scans to show that London taxi drivers had increased grey matter in the posterior hippocampus, demonstrating brain plasticity in response to extensive spatial navigation experience.
Sperry 的裂脑研究揭示了半球功能偏侧化：左半球主要负责语言生成，而右半球在空间和视觉运动任务中占优势。Maguire 等人使用 MRI 扫描显示伦敦出租车司机后海马体灰质增加，证明大脑因应广泛的空间导航经验而出现可塑性。
Casey et al. conducted a longitudinal study, finding that those who could delay gratification at age 4 and maintained high self-control in their 20s and 30s showed enhanced activity in the right inferior frontal gyrus, linking self-regulation to a specific brain region. Blakemore and Cooper’s classic experiment with kittens raised in striped environments showed that early visual experience shapes cortical neuron orientation selectivity, providing strong evidence for the interaction of nature and nurture.
Casey 等人进行了一项纵向研究，发现那些在 4 岁时能延迟满足并在 20 多岁和 30 多岁时保持高自我控制的人，其右侧额下回活动增强，将自我调节与特定脑区联系了起来。Blakemore 和 Cooper 用条纹环境中养育的小猫进行的经典实验表明，早期视觉经验塑造了皮层神经元的朝向选择性，为先天与后天的交互作用提供了有力证据。
4. Social Psychology | 社会心理学
The social approach examines how our thoughts, feelings, and behaviours are influenced by the actual or imagined presence of others. Core studies include Milgram (1963) on obedience, Bocchiaro et al. (2012) on obedience and whistleblowing, Piliavin et al. (1969) on bystander intervention, and Levine et al. (2001) on cross-cultural helping.
社会视角考察我们的思想、情感和行为如何被他人实际或想象的存在所影响。核心研究包括 Milgram (1963) 关于服从的研究、Bocchiaro 等人 (2012) 关于服从与举报的研究、Piliavin 等人 (1969) 关于旁观者干预的研究以及 Levine 等人 (2001) 关于跨文化助人行为的研究。
Milgram’s obedience study showed that 65% of participants administered the maximum 450-volt shock under an authority figure’s instruction, illustrating the power of the situation. Bocchiaro et al. extended this by investigating whistleblowing, finding that while most participants predicted they would disobey, the majority actually obeyed an unethical request, with only 14% blowing the whistle.
Milgram 的服从研究显示，65% 的参与者在权威人物的指令下施加了最高 450 伏的电击，说明了情境的力量。Bocchiaro 等人通过研究举报行为进行了扩展，发现尽管大多数参与者预测自己会不服从，但实际上大多数人服从了不道德的请求，仅有 14% 的人进行了举报。
Piliavin et al.’s field experiment on a subway train revealed that help is more likely when the victim appears ill rather than drunk, and the number of bystanders does not always produce a diffusion of responsibility. Levine et al. carried out a cross-cultural study in 23 cities and found that simpatia cultures (e.g., Brazil, Mexico) showed significantly higher helping rates, emphasising cultural norms in prosocial behaviour.
Piliavin 等人在地铁上的现场实验表明，当受害者看似生病而非醉酒时，更可能获得帮助，并且旁观者人数并不总是导致责任扩散。Levine 等人在 23 个城市进行的跨文化研究发现，重视亲和性的文化（如巴西、墨西哥）助人率显著更高，强调了亲社会行为中的文化规范。
5. Developmental Psychology | 发展心理学
This approach explores how behaviour and thinking change across the lifespan. The four core studies are Bandura et al. (1961) on imitation of aggression, Chaney et al. (2004) on operant conditioning and inhaler use, Kohlberg (1968) on moral reasoning, and Lee et al. (1997) on cross-cultural differences in moral evaluations of lying.
该视角探讨行为和思维在人生全程中如何变化。四项核心研究分别是 Bandura 等人 (1961) 关于攻击性模仿的研究、Chaney 等人 (2004) 关于操作条件作用与吸入器使用的研究、Kohlberg (1968) 关于道德推理的研究以及 Lee 等人 (1997) 关于说谎道德评价的跨文化差异的研究。
Bandura’s Bobo doll experiment demonstrated observational learning, with children who observed an aggressive model subsequently displaying more physical and verbal aggression. This supports social learning theory, highlighting the role of vicarious reinforcement. Chaney et al. used the Funhaler, which utilised positive reinforcement (a whistle and spinner) to improve adherence to inhaled medication in asthmatic children, a clear real-world application of operant conditioning.
Bandura 的波波玩偶实验展示了观察学习，观察到攻击性榜样的儿童随后表现出更多身体和言语攻击，这支持了社会学习理论，突显了替代强化的作用。Chaney 等人使用 Funhaler（趣味吸入器），利用正强化（哨子和转盘）提高了哮喘儿童吸入药物的依从性，这是操作条件作用在现实世界中的明确应用。
Kohlberg’s moral development theory proposed three levels of moral reasoning: pre-conventional, conventional, and post-conventional. His study used moral dilemmas like Heinz to assess stage progression. Lee et al. found that Chinese children rated truth-telling less positively and lying for modesty more positively than Canadian children, illustrating the cultural relativity of moral values, which challenges Kohlberg’s universal stage model.
Kohlberg 的道德发展理论提出了道德推理的三个水平：前习俗水平、习俗水平和后习俗水平。他的研究使用海因茨等道德困境来评估阶段进展。Lee 等人发现，中国儿童对说真话的正面评价低于加拿大儿童，而对谦虚谎言则有更积极的评价，这说明道德价值观具有文化相对性，挑战了 Kohlberg 的普遍阶段模型。
6. Individual Differences | 个体差异
The individual differences approach focuses on what makes people different from one another, exploring personality, intelligence, and psychological functioning. Core studies are Freud (1909) Little Hans, Baron-Cohen et al. (1997) theory of mind in autism, Gould (1982) a review of Yerkes’ intelligence testing, and Hancock et al. (2011) language of psychopaths.
个体差异视角关注使人彼此相异的因素，探索人格、智力和心理功能。核心研究包括 Freud (1909) 的小汉斯案例、Baron-Cohen 等人 (1997) 关于自闭症心理理论的研究、Gould (1982) 对 Yerkes 智力测验的回顾以及 Hancock 等人 (2011) 关于精神病态者语言的研究。
Freud’s Little Hans case study was used as evidence for the Oedipus complex and psychosexual stages, demonstrating the influence of unconscious conflicts on phobias. Baron-Cohen et al.’s Eyes Task showed that adults with high-functioning autism or Asperger syndrome had a significant impairment in theory of mind, providing a cognitive explanation for social difficulties in autism.
Freud 的小汉斯个案研究被用作俄狄浦斯情结和心理性欲阶段的证据，展示了无意识冲突对恐惧症的影响。Baron-Cohen 等人的眼神读心任务显示，高功能自闭症或阿斯伯格综合征成人存在心理理论的明显缺损，为自闭症中的社交困难提供了一种认知解释。
Gould’s review critiqued Yerkes’ army alpha and beta tests, highlighting cultural, educational, and linguistic biases that led to flawed conclusions about the intellectual inferiority of certain ethnic groups. Hancock et al. analysed language samples of psychopathic murderers, finding that they used more subordinating conjunctions, instrumental language, and fewer positive emotion words, linking language patterns to psychological disorders.
Gould 的回顾批判了 Yerkes 的军队阿尔法和贝塔测验，揭示了导致某些族裔智力低下这一错误结论的文化、教育和语言偏差。Hancock 等人分析了具有精神病态特征谋杀犯的语言样本，发现他们使用了更多的从属连词、工具性语言和更少的积极情绪词汇，将语言模式与心理障碍联系了起来。
7. Psychopathology | 心理病理学
Psychopathology studies examine the nature and treatment of mental disorders. The two core studies representing this approach are Rosenhan (1973) ‘On Being Sane in Insane Places’ and Watson & Rayner (1920) ‘Little Albert’. These studies are often discussed alongside individual differences but provide distinct insight into diagnostic reliability and the learning of phobias.
心理病理学研究考察心理障碍的性质与治疗。代表该视角的两项核心研究是 Rosenhan (1973) 的’精神病院中的正常人’以及 Watson 和 Rayner (1920) 的’小阿尔伯特’。这些研究常与个体差异一同讨论，但在诊断可靠性和恐惧症的学习方面提供了独特的见解。
Rosenhan’s field study sent eight pseudopatients to 12 psychiatric hospitals, all of whom were admitted and mostly diagnosed with schizophrenia. Once inside, they behaved normally, yet their normal behaviours were interpreted as pathological. This exposed the unreliability of psychiatric diagnosis and the power of labelling. Watson and Rayner classically conditioned a fear response to a white rat in an infant, which generalised to other furry objects, demonstrating that phobias could be acquired through simple conditioning.
Rosenhan 的现场研究派八名假病人进入十二家精神病院，所有人均被收治且多数被诊断为精神分裂症。入院后他们行为正常，但正常行为被解读为病态。这暴露了精神病诊断的不可靠性和标签的力量。Watson 和 Rayner 通过经典条件作用使一名婴儿对白鼠产生恐惧反应，并泛化到其他有毛物体，证明恐惧症可以通过简单条件作用习得。
Both studies raise profound ethical issues. Rosenhan involved deception and potential harm to institutions and staff, while Watson and Rayner induced distress in a child with no attempt at deconditioning. They also fuel the debate on whether mental disorders are primarily biological or learned, and whether diagnostic systems are culturally biased.
这两项研究都引发了深刻的伦理问题。Rosenhan 涉及欺骗和对机构及工作人员可能造成的伤害，而 Watson 和 Rayner 则给一名儿童造成了痛苦且未尝试消除条件作用。它们还助长了关于心理障碍主要是生物性的还是后天习得的、以及诊断系统是否存在文化偏见的争论。
8. Research Methods | 研究方法
Understanding research methodology is crucial for the Pre-U course. You need to evaluate how studies use experiments (laboratory, field, quasi), observations, self-reports, and case studies. Key concepts include internal and external validity, reliability, sampling techniques, and ethical guidelines such as informed consent, protection from harm, and debriefing.
理解研究方法对 Pre-U 课程至关重要。你需要评估研究如何使用实验（实验室、现场、准实验）、观察、自我报告和个案研究。关键概念包括内部效度和外部效度、信度、抽样技术以及伦理准则，如知情同意、免受伤害保护和事后解释。
For example, Moray’s auditory attention experiments are laboratory-based, offering high internal validity but weaker ecological validity. In contrast, Piliavin et al.’s field experiment has strong ecological validity but less control over extraneous variables. Case studies like Freud’s Little Hans provide rich qualitative data but suffer from low replicability and researcher bias.
例如，Moray 的听觉注意实验是在实验室进行的，内部效度高但生态效度较弱。
