1. The Scientific Nature of Psychology | 心理学的科学本质
Psychology is defined as the scientific study of the mind and behaviour. Unlike everyday ‘common sense’ explanations, psychological research relies on empirical evidence – data gathered through direct observation or experiment. This means that psychologists formulate theories, derive hypotheses, and test them under controlled conditions. Replicability and objectivity are key principles that distinguish psychology from pseudoscience.
心理学被定义为对心理和行为的科学研究。与日常的“常识”解释不同，心理学研究依赖于经验证据——通过直接观察或实验收集的数据。这意味着心理学家提出理论、推导假设，并在受控条件下进行检验。可重复性和客观性是区分心理学与伪科学的关键原则。
2. Research Methods: Experiments and Variables | 研究方法：实验与变量
Experiments are the most powerful tool in a psychologist’s toolkit for establishing cause-and-effect relationships. The independent variable (IV) is the factor that the researcher manipulates, and the dependent variable (DV) is the factor that is measured. All other variables must be carefully controlled so they do not become confounding variables. Standardised procedures ensure that each participant experiences the same environment, increasing the study’s reliability.
实验是心理学家用以建立因果关系的最有力工具。自变量（IV）是研究者操控的因素，因变量（DV）是测量的因素。所有其他变量必须仔细控制，以免成为混淆变量。标准化程序确保每位被试经历相同的环境，从而提高研究的信度。
There are three main types of experiments you need to know. In a laboratory experiment, the IV is manipulated in a highly controlled, artificial setting. A field experiment manipulates the IV in a natural, real-world environment, increasing ecological validity. A quasi-experiment does not involve direct manipulation of the IV; instead, it uses naturally occurring differences, such as gender or age, which means random allocation is not possible.
你需要了解三种主要实验类型。实验室实验中，自变量在高度受控的人工环境中被操纵。现场实验在自然的真实世界环境中操纵自变量，提高了生态效度。准实验不直接操纵自变量；它利用自然存在的差异，如性别或年龄，这意味着无法进行随机分配。
3. Research Methods: Sampling and Ethics | 研究方法：抽样与伦理
A sample is a group of participants drawn from a target population. Random sampling gives every member of the population an equal chance of being selected, reducing bias. Opportunity sampling uses participants who are readily available, which is convenient but less representative. Self-selected sampling relies on volunteers, which can lead to a biased sample of highly motivated individuals. Researchers must also follow strict ethical guidelines set by the British Psychological Society (BPS), including informed consent, right to withdraw, protection from harm, deception and debriefing, and confidentiality.
样本是从目标人群中抽取的一组参与者。随机抽样给予总体中每个成员同等的被选机会，减少了偏差。机会抽样使用容易获得的参与者，方便但代表性较差。自愿抽样依赖于志愿者，这可能导致样本偏向于积极性高的人。研究者还必须遵循英国心理学会（BPS）制定的严格伦理准则，包括知情同意、退出权、免受伤害、欺骗与事后解释以及保密性。
4. Social Influence: Conformity and Asch | 社会影响：从众与阿希
Conformity is a change in a person’s behaviour or opinions as a result of real or imagined pressure from a group. Solomon Asch (1951) demonstrated this using a line-judgment task. Participants were placed in a group of confederates who deliberately gave wrong answers. About 37% of the responses were conforming errors. Asch identified two types of social influence: normative social influence, where we conform to be liked and gain social approval, and informational social influence, where we conform because we assume the group knows better.
从众是指个人由于来自群体的真实或想象的压力而改变行为或观点。所罗门·阿希（1951）通过一个线段判断任务验证了这一点。参与者与一群故意给出错误答案的假被试同组。大约37%的反应是从众的错误。阿希识别出两种社会影响：规范型社会影响，即我们为了被喜欢和获得社会认可而服从；信息型社会影响，即我们因为认为群体更清楚而服从。
5. Social Influence: Obedience and Milgram | 社会影响：服从与米尔格拉姆
Obedience is complying with the direct orders of an authority figure. Stanley Milgram (1963) conducted a now-famous obedience study at Yale University. Participants believed they were delivering increasingly severe electric shocks to a learner (a confederate). An alarming 65% of participants administered the maximum 450-volt shock. Milgram concluded that ordinary people are likely to follow orders given by an authority figure, even to the extent of harming others, due to the agentic state where they shift responsibility to the authority.
服从是听从权威人物直接命令的行为。斯坦利·米尔格拉姆（1963）在耶鲁大学进行了一项如今著名的服从研究。参与者以为自己在对一名学习者（假被试）施加越来越强的电击。令人震惊的是，65%的参与者施加了最高450伏的电击。米尔格拉姆得出结论，普通人很可能听从权威人物的命令，甚至达到伤害他人的程度，这是因为代理状态，他们将责任转移给了权威。
6. Memory: Multi-Store Model | 记忆：多储存模型
Atkinson and Shiffrin (1968) proposed the Multi-Store Model of memory (MSM), which describes memory as a flow of information through three separate stores. Information enters the sensory register, where it is held in a raw, unprocessed form for less than half a second. If attention is paid, it passes to short-term memory (STM), which has a limited capacity of 7±2 items and a duration of around 18–30 seconds. Maintenance rehearsal can then transfer information to long-term memory (LTM), which has potentially unlimited capacity and duration.
阿特金森和希夫林（1968）提出了记忆的多储存模型（MSM），将记忆描述为信息流经三个独立储存器。信息进入感觉登记器，以原始未加工的形式保持不到半秒。如果加以注意，信息进入短时记忆（STM），STM容量有限，为7±2个组块，持续时间约为18–30秒。维持性复述可以将信息转入长时记忆（LTM），LTM容量和持续时间可能无限。
| Store | Capacity | Duration | Encoding |
|---|---|---|---|
| Sensory Register | Very large | < 0.5 seconds | Modality-specific |
| Short-Term Memory | 7 ± 2 chunks | 18–30 seconds | Acoustic primarily |
| Long-Term Memory | Unlimited | Potentially permanent | Semantic |
表格总结：多储存模型中三种储存器的容量、持续时间和编码方式。感觉登记器容量很大但不到半秒；短时记忆为7±2个组块，持续18–30秒，主要是听觉编码；长时记忆容量无限，可能是永久的，以语义编码为主。
7. Memory: Forgetting and Eyewitness Testimony | 记忆：遗忘与目击证词
Forgetting from STM occurs through displacement or decay unless information is rehearsed. Forgetting from LTM can be explained by interference theory, where new or old memories disrupt retrieval, or by retrieval failure due to absence of cues. Eyewitness testimony (EWT) refers to the accounts people give of events they have witnessed. Elizabeth Loftus’ research showed that leading questions can distort memory. For example, the verb ‘smashed’ in the question made participants estimate a higher speed than the verb ‘contacted’. Memory is reconstructive, and post-event information can alter the original memory trace.
短时记忆的遗忘是由于信息被取代或衰退，除非进行复述。长时记忆的遗忘可以用干扰理论来解释，即新旧记忆干扰提取，或因线索缺失导致提取失败。目击证词（EWT）指人们对所见事件的叙述。伊丽莎白·洛夫特斯的研究表明，诱导性问题会扭曲记忆。例如，问题中使用“撞毁”一词比使用“接触”一词使参与者估计的车速更高。记忆是可重构的，事后信息可以改变原始记忆痕迹。
8. Development: Piaget’s Theory of Cognitive Development | 发展：皮亚杰的认知发展理论
Jean Piaget proposed that children’s thinking is not just a less complex version of adult thinking, but qualitatively different. He identified four universal stages. The sensorimotor stage (0–2 years) is when infants learn through senses and actions, and develop object permanence. The pre-operational stage (2–7 years) features egocentrism and the inability to conserve. The concrete operational stage (7–11 years) brings logical thinking about concrete objects, with mastery of conservation and class inclusion. The formal operational stage (11+ years) enables abstract and systematic reasoning.
让·皮亚杰提出，儿童的思维不仅是成人思维的简化版，而是质的不同。他确定了四个普遍阶段。感觉运动阶段（0–2岁）婴儿通过感官和动作学习，发展客体永久性。前运算阶段（2–7岁）以自我中心和无法进行守恒为特征。具体运算阶段（7–11岁）能够对具体事物进行逻辑思考，掌握守恒和类包含。形式运算阶段（11岁以上）能够进行抽象和系统推理。
Piaget used clinical interviews and observation, such as the conservation of number task. Children in the pre-operational stage fail to understand that rearranging counters does not change the quantity, whereas children in the concrete operational stage grasp this. However, critics argue that Piaget underestimated children’s abilities and that cognitive development may be more continuous than stage-like.
皮亚杰采用临床访谈和观察，如数量守恒任务。前运算阶段的儿童无法理解重新排列筹码不会改变数量，而具体运算阶段的儿童能掌握这一点。然而，批评者认为皮亚杰低估了儿童的能力，且认知发展可能更多是连续的而非呈阶段式。
9. Development: Brain Development and Intelligence | 发展：大脑发育与智力
During adolescence, the brain undergoes significant changes. The prefrontal cortex, responsible for decision-making and impulse control, is one of the last regions to mature. This explains some risk-taking behaviours in teenagers. In the OCR specification, you also examine the role of education and intelligence. Fluid intelligence involves logical problem-solving without prior knowledge, while crystallised intelligence involves using learned knowledge and experience. The concept of a growth mindset, introduced by Carol Dweck, emphasises that intelligence can be developed through effort and learning, contrasting with a fixed mindset where ability is seen as static.
青少年时期大脑经历显著变化。负责决策和冲动控制的前额叶皮层是最后成熟的区域之一。这解释了青少年的一些冒险行为。在OCR考纲中，你还需要考察教育与智力的作用。流体智力涉及没有先验知识的逻辑问题解决，而晶体智力涉及使用学到的知识和经验。卡罗尔·德韦克提出的成长型思维强调，智力可以通过努力和学习发展，与能力被视为一成不变的固定型思维形成对比。
10. Psychological Problems: Mental Health and Disorder | 心理问题：心理健康与障碍
Mental health is a continuum from flourishing to severely disabling disorders. The OCR specification focuses on depression and addiction as key mental health problems. Depression is characterised by persistent low mood, loss of interest (anhedonia), and feelings of worthlessness. The biological explanation highlights the serotonin hypothesis and genetic vulnerability. The psychological explanation cites negative schemas (Beck) and learned helplessness (Seligman). Addiction involves compulsive engagement in rewarding stimuli despite adverse consequences. Biological explanations refer to the dopamine reward pathway, while psychological explanations focus on operant conditioning and social learning.
心理健康是一个从蓬勃发展到严重致残障碍的连续谱。OCR考纲重点关注抑郁症和成瘾作为关键心理健康问题。抑郁症的特征是持续的情绪低落、兴趣丧失（快感缺失）和无价值感。生物学解释强调血清素假说和基因易感性。心理学解释引用消极图式（贝克）和习得性无助（塞利格曼）。成瘾包括尽管有不良后果仍强迫性地从事奖励性刺激。生物学解释涉及多巴胺奖赏通路，而心理学解释侧重于操作性条件作用和社会学习。
11. Psychological Problems: Treatments and Therapies | 心理问题：治疗与疗法
Treatments for psychological disorders can be broadly divided into biological and psychological approaches. For depression, selective serotonin reuptake inhibitors (SSRIs) aim to increase serotonin levels at the synapse. Cognitive Behavioural Therapy (CBT) is a psychological treatment that helps patients identify and challenge irrational thoughts. For addiction, aversion therapy involves pairing an addictive substance with an unpleasant stimulus, while self-management programmes and support groups like Alcoholics Anonymous provide structured recovery. It is essential to evaluate the effectiveness and ethical implications of any treatment.
心理障碍的治疗可大致分为生物学方法和心理学方法。对于抑郁症，选择性5-羟色胺再摄取抑制剂（SSRIs）旨在增加突触中的血清素水平。认知行为疗法（CBT）是一种心理治疗，帮助患者识别和挑战非理性思维。对于成瘾，厌恶疗法涉及将成瘾物质与不愉快刺激配对，而自我管理项目和如匿名戒酒会等支持团体提供结构化的康复。必须评估任何治疗的有效性和伦理含义。
12. Synthesising Research Methods with Core Topics | 研究方法与核心主题的融合
Throughout Year 10, you are expected to apply research methods knowledge to every topic. For instance, when you study Asch’s conformity experiment, you should identify the IV (group presence or absence), the DV (conformity rate), and the experimental design (independent measures). Similarly, for Piaget’s conservation tasks, consider the use of the clinical method as a quasi-experiment and discuss issues of validity and reliability. Always link theories back to their supporting and challenging evidence, and be prepared to evaluate studies using GRAVE criteria: Generalisability, Reliability, Applicability, Validity, and Ethics.
在整个10年级，你需要将研究方法知识应用到每个主题。例如，当你学习阿希的从众实验时，应识别出IV（群体存在与否）、DV（从从率）和实验设计（独立测量）。同样，对于皮亚杰的守恒任务，考虑临床方法的使用作为准实验，并讨论效度和信度问题。始终将理论与其支持和挑战的证据联系起来，并准备使用GRAVE标准评估研究：可推广性、信度、应用性、效度和伦理学。
