这份复习指南涵盖了 Year 11 OCR GCSE 心理学的核心主题。每个部分都呈现了你需要掌握的关鍵理论、研究和概念，并用清晰的中英双语解释支持你的学习。
1. Research Methods and Experimental Design | 研究方法与实验设计
Psychologists use experiments, observations, questionnaires, interviews, and case studies to investigate behaviour. An independent variable (IV) is manipulated to measure its effect on a dependent variable (DV).
心理学家使用实验、观察、问卷、访谈和案例研究来调查行为。自变量（IV）被操控以测量其对因变量（DV）的影响。
Experimental designs include independent groups, repeated measures, and matched pairs. Each has strengths and weaknesses, such as order effects in repeated measures or participant variables in independent groups.
实验设计包括独立组设计、重复测量设计和配对组设计。每种设计都有优缺点，例如重复测量设计中的顺序效应，或独立组设计中的被试变量。
Control of extraneous variables is crucial. Standardisation, randomisation, and counterbalancing help reduce bias and increase internal validity.
控制额外变量至关重要。标准化、随机化和平衡法有助于减少偏差并提高内部效度。
2. Memory Models and Forgetting | 记忆模型与遗忘
Atkinson & Shiffrin’s multi-store model describes three separate stores: sensory memory, short-term memory (STM), and long-term memory (LTM). Information moves between them through attention and rehearsal.
阿特金森和谢夫林的多储存模型描述了三个独立的储存库：感觉记忆、短时记忆（STM）和长时记忆（LTM）。信息通过注意和复述在它们之间移动。
Baddeley and Hitch’s working memory model replaced the idea of a unitary STM. It includes the central executive, phonological loop, visuospatial sketchpad, and episodic buffer.
巴德利和希奇的工作记忆模型取代了单一短时记忆的观点。它包括中央执行器、语音回路、视空间画板和情景缓冲器。
Forgetting can be explained by decay, displacement, and retrieval failure. Peterson & Peterson showed that STM duration is around 18–30 seconds without rehearsal. Godden & Baddeley’s diving study demonstrated context-dependent forgetting.
遗忘可以用衰退、干扰和提取失败来解释。彼得森夫妇的研究表明，如果没有复述，短时记忆的持续时间约为18-30秒。戈登和巴德利的潜水实验证明了情境依赖遗忘。
3. Sensation and Perception | 感觉与知觉
Sensation is the detection of physical stimuli by sense organs. Perception is how the brain interprets these sensations. The difference between the two is shown in visual illusions.
感觉是感觉器官对物理刺激的检测。知觉是大脑如何解释这些感觉。两者之间的区别在视错觉中体现出来。
Gregory’s constructivist theory argues that perception is actively built using past experience and expectations. Visual illusions occur when inferences are incorrect.
格雷戈里的建构主义理论认为，知觉是利用过去的经验和期望主动构建的。当推论不正确时就产生视错觉。
Gibson’s direct theory claims that perception is automatic and does not require prior learning. The environment provides sufficient cues like texture gradient and optic flow.
吉布森的直接理论声称知觉是自动的，不需要先前学习。环境提供了足够的线索，如纹理梯度和光流。
Key studies include Haber and Levin (2001) on depth cues in the real world, and Gregory’s work on perceptual set influenced by culture and experience.
关键研究包括哈伯和莱文（2001）关于真实世界中深度线索的研究，以及格雷戈里关于由文化和经验影响的知觉定势的研究。
4. Development: Piaget’s Stages and Beyond | 发展心理学：皮亚杰阶段及之后
Piaget’s theory of cognitive development includes four stages: sensorimotor (0–2 years), pre-operational (2–7 years), concrete operational (7–11 years), and formal operational (11+ years).
皮亚杰的认知发展理论包含四个阶段：感知运动阶段（0-2岁）、前运算阶段（2-7岁）、具体运算阶段（7-11岁）和形式运算阶段（11岁以上）。
Conservation is the understanding that quantity remains the same despite changes in appearance. Piaget’s classic liquid conservation task showed that children in the pre-operational stage lack this concept.
守恒是指尽管外观发生变化，数量仍保持不变的理解。皮亚杰的经典液体守恒任务表明，前运算阶段的儿童缺乏这一概念。
Vygotsky emphasised the role of social interaction and culture, proposing the zone of proximal development (ZPD) and scaffolding. McGarrigle and Donaldson challenged Piaget, showing that making the change in conservation tasks appear accidental improved children’s answers.
维果茨基强调社会互动和文化的作用，提出了最近发展区（ZPD）和支架的概念。麦加里格和唐纳森对皮亚杰提出质疑，表明让守恒任务中的变化看起来像是意外，能改善儿童的回答。
5. Social Influence: Conformity and Obedience | 社会影响：从众与服从
Conformity is a change in behaviour or belief due to real or imagined group pressure. Asch’s line study (1951) demonstrated normative social influence, where 75% of participants conformed at least once.
从众是由于真实或想象的群体压力而导致的行为或信念改变。阿希的线条实验（1951）展示了规范性社会影响，75% 的被试至少从众一次。
Obedience involves following direct commands from an authority figure. Milgram’s electric shock experiment (1963) found that 65% of participants administered the maximum 450V shock when ordered by an experimenter.
服从涉及遵循权威人物的直接命令。米尔格拉姆的电击实验（1963）发现，65% 的被试在实验者命令下施加了最高 450 伏的电击。
Situational factors affecting obedience include proximity, location, and uniform. Milgram’s variations showed that obedience dropped when the experimenter was absent or the teacher was close to the learner.
影响服从的情境因素包括接近程度、地点和制服。米尔格拉姆的变式实验表明，当实验者不在场或老师靠近学习者时，服从程度下降。
Social identity theory (Tajfel) explains how group membership leads to in-group favouritism and out-group discrimination, influencing behaviour and prejudice.
社会认同理论（塔吉费爾）解释了群体成员身份如何导致内群体偏爱和外群体歧视，并影响行为和偏见。
6. Psychological Problems: Depression and Schizophrenia | 心理问题：抑郁症与精神分裂症
The medical model views mental disorders as illnesses with biological causes, such as neurotransmitter imbalances. The cognitive approach links depression to faulty thinking patterns.
医学模型将心理障碍视为有生物原因的疾病，例如神经递质失衡。认知方法将抑郁症与错误的思维模式联系起来。
Beck’s negative triad describes depressed individuals’ automatic negative thoughts about the self, the world, and the future. Ellis’s ABC model explains how irrational beliefs (B) lead to negative emotional consequences (C) from activating events (A).
贝克的消极三合一描述了抑郁症患者对自我、世界和未来的自动消极思维。艾利斯的 ABC 模型解释了非理性信念（B）如何导致由激发事件（A）产生的负面情绪后果（C）。
Schizophrenia symptoms include hallucinations, delusions, and disorganised speech. Gottesman’s twin study found a 48% concordance rate for identical twins, suggesting a strong genetic component.
精神分裂症的症状包括幻觉、妄想和言语紊乱。戈特斯曼的双胞胎研究发现同卵双胞胎的一致率为 48%，表明强烈的遗传成分。
Treatments range from CBT (challenging irrational thoughts) to drug therapies (antidepressants like SSRIs, antipsychotics that block dopamine). Each has strengths and limitations regarding side effects and effectiveness.
治疗方法从 CBT（挑戰非理性思想）到药物疗法（如 SSRIs 抗抑郁药，阻断多巴胺的抗精神病药）。每种疗法在副作用和有效性方面各有优缺点。
7. The Brain and Neuropsychology | 大脑与神经心理学
The central nervous system consists of the brain and spinal cord. Key brain areas include the frontal lobe (decision-making), temporal lobe (auditory processing), parietal lobe (sensory information), and occipital lobe (vision).
中枢神经系统由大脑和脊髓组成。关键脑区包括额叶（决策）、颞叶（听觉处理）、顶叶（感觉信息）和枕叶（视觉）。
Localisation of function means specific brain regions are responsible for specific tasks. Broca’s area is linked to speech production, while Wernicke’s area is linked to language comprehension.
功能定位意味着特定脑区负责特定任务。布洛卡区与言语产生相关，韦尼克区与语言理解相关。
Neuroplasticity is the brain’s ability to change and reorganise itself throughout life. The case of Jodie Miller, who had a hemispherectomy, shows how the remaining hemisphere can take over functions.
神经可塑性是大脑在生命过程中改变和重组自身的能力。乔迪·米勒接受大脑半球切除术的案例显示了剩余半球如何接管功能。
Techniques like fMRI, EEG, and PET scans allow psychologists to investigate brain structure and activity. Tulving’s PET scan study showed episodic and semantic memories activate different brain areas.
fMRI、EEG 和 PET 扫描等技术使心理学家能够研究大脑结构和活动。托尔文的 PET 扫描研究显示，情景记忆和语义记忆激活不同的脑区。
8. Research Ethics and Validity | 研究伦理与效度
The British Psychological Society (BPS) ethical guidelines require researchers to obtain informed consent, avoid deception wherever possible, protect participants from harm, ensure confidentiality, and provide a full debrief.
英国心理学会（BPS）的伦理准则要求研究者获得知情同意、尽可能避免欺骗、保护参与者免受伤害、确保保密性，并提供完整的任务报告。
Informed consent must be given freely, and participants have the right to withdraw at any time without penalty. When children under 16 are involved, parental consent is needed.
知情同意必须是自由给予的，参与者有权在任何时候退出而不受惩罚。涉及 16 岁以下儿童时，需要父母同意。
Internal validity refers to whether the study truly measures what it intends to. External validity (ecological and population) concerns how generalisable findings are. Reliability is about consistency of results.
内部效度指研究是否真正测量了它想要测量的东西。外部效度（生态效度和人口效度）涉及研究结果的泛化程度。信度是关于结果的一致性。
9. Data Handling and Analysis | 数据处理与分析
Quantitative data is numerical and can be analysed statistically. Qualitative data is non-numerical (e.g., interview transcripts) and focuses on meaning and experience.
定量数据是数字形式的，可以统计性地分析。定性数据是非数字的（如访谈记录），侧重于意义和体验。
Measures of central tendency include mean, median, and mode. The mean is the average, the median is the middle value, and the mode is the most frequent score. The mean is sensitive to extreme values.
集中量数包括平均数、中位数和众数。平均数是算术平均，中位数是中间值，众数是出现最频繁的数值。平均数易受极端值影响。
Scatter graphs show correlations: positive (as one variable increases, so does the other), negative (one increases, the other decreases), and zero (no relationship). A correlation coefficient (e.g., +0.7) indicates strength and direction.
散点图显示相关关系：正相关（一个变量增加，另一个也增加），负相关（一个增加，另一个减少）和零相关（无关）。相关系数（如 +0.7）表示强度和方向。
10. Key Studies and Applications | 关键研究与应用
Memory: Peterson & Peterson (1959) tested STM duration using trigrams and a distracter task. Conclusion: STM lasts about 18 seconds without rehearsal.
记忆：彼得森夫妇（1959）使用三字母组和干扰任务测试短时记忆持续时间。结论：若无复述，短时记忆约持续 18 秒。
Development: Piaget’s conservation of number task (1952) demonstrated that pre-operational children cannot conserve. Hughes’ policeman doll study (1975) showed that with meaningful tasks, younger children could take another’s perspective.
发展：皮亚杰的数字守恒任务（1952）表明前运算阶段儿童无法守恒。休斯的警察玩偶研究（1975）显示，在有意义的任务中，年幼儿童能夠采取他人的视角。
Social influence: Asch (1951) conformity study showed the power of group pressure. Zimbardo’s Stanford Prison Experiment (1973) demonstrated how social roles and norms affect behaviour, though it was highly unethical.
社会影响：阿希（1951）从众研究显示了群体压力的力量。津巴多的斯坦福监狱实验（1973）展示了社会角色和规范如何影响行为，尽管极不道德。
Psychological problems: Gottesman & Shields (1972) twin study found 58% concordance in MZ twins for schizophrenia using the DSM classification. Baker & Morrison (1998) compared CBT with drug therapy.
心理问题：戈特斯曼和希尔兹（1972）的双胞胎研究使用 DSM 分类发现同卵双胞胎的精神分裂症一致率为 58%。贝克和莫里森（1998）比较了 CBT 与药物治疗。
11. Exam Technique and Command Words | 考试技巧与指令词
Command words like ‘describe’, ‘explain’, ‘evaluate’, and ‘compare’ require different responses. ‘Evaluate’ means you must give strengths and weaknesses, supported by evidence.
指令词如“描述”、“解释”、“评价”和“比较”需要不同的回答。”评价”意味着你必须给出优缺点，并用证据支持。
For a 9-mark question, structure your answer with a clear point, evidence/example, and explanation (PEE). Application questions ask you to relate psychological knowledge to a given scenario.
对于 9 分题，用清晰的观点、证据/例子和解释（PEE）来组织你的答案。应用题要求你将心理学知识与给定情景联系起来。
Timing is crucial: allocate roughly one minute per mark. Always refer back to the study or theory named in the question to avoid vague answers.
时间管理至关重要：大約每 1 分分配一分钟。始终回扣题目中指定的研究或理论，避免模糊的答案。
12. Synoptic Thinking and Linking Topics | 综摄思维与主题联系
OCR exams often require you to connect ideas across topics. For example, you could link social influence (obedience) with ethics (Milgram’s lack of protection from harm).
OCR 考试常常要求你跨主题连接观点。例如，你可以將社会影响（服从）与伦理（米尔格拉姆研究中缺乏保护免受伤害）联系起来。
Memory research methods can be applied to development: a study on conservation might use an independent groups design. Understanding neuropsychology helps explain symptoms of schizophrenia (dopamine hypothesis).
记忆研究方法可以应用于发展心理学：守恒研究可能使用独立组设计。理解神经心理学有助于解释精神分裂症的症状（多巴胺假说）。
When writing essays, demonstrate how key themes like nature vs. nurture, reductionism vs. holism, and validity run throughout the syllabus. This shows higher-order thinking.
在撰写论文时，展示先天与后天、还原论与整体论、效度等关键主题如何贯穿整个课程。这体现了高阶思维能力。
