1. Behaviourist Approach | 行为主义流派
The behaviourist approach assumes that all behaviours are learned through interaction with the environment. Only observable behaviours should be studied scientifically, ignoring internal mental processes because they cannot be directly observed.
行为主义流派假设所有行为都是通过与环境的互动习得的。只有可观察的行为才应该被科学地研究，忽略内部心理过程，因为它们无法被直接观察。
Classical conditioning, discovered by Ivan Pavlov, involves learning through association. A neutral stimulus can eventually trigger a conditioned response after being repeatedly paired with an unconditioned stimulus. This was famously demonstrated in Watson and Rayner’s (1920) “Little Albert” study, where a child was conditioned to fear a white rat.
经典条件作用由伊万·巴甫洛夫发现，涉及通过联想进行学习。一个中性刺激在与无条件刺激反复配对后，最终可以引发条件反应。这在华生和雷纳（1920）的 “小阿尔伯特” 实验中得到了著名展示，一名儿童被条件化地对白鼠产生恐惧。
Operant conditioning, proposed by B. F. Skinner, explains how behaviour is shaped by consequences. Reinforcement (positive or negative) strengthens a behaviour, while punishment weakens it. Skinner’s box experiments with rats and pigeons demonstrated principles like reinforcement schedules and shaping.
操作条件作用由斯金纳提出，解释了行为如何被后果所塑造。强化（正强化或负强化）增强行为，而惩罚削弱行为。斯金纳箱用大鼠和鸽子进行的实验展示了强化程式和塑造等原则。
Behavioural therapies include systematic desensitisation, which uses counterconditioning and relaxation to treat phobias gradually, and token economies, where desirable behaviours are reinforced with tokens exchangeable for rewards, often used in institutions.
行为疗法包括系统脱敏，它利用反条件作用和放松技术逐步治疗恐惧症；以及代币经济法，即用可兑换奖励的代币强化目标行为，常用于机构环境中。
A major strength of the behaviourist approach is its scientific rigour: it relies on controlled experiments and measurable behavioural data. However, critics argue it is overly reductionist, ignoring cognitive and emotional factors, and that animal research findings may not fully generalise to humans.
行为主义流派的一大优势是其科学严谨性：它依赖控制实验和可测量的行为数据。然而批评者认为它过于还原论，忽视了认知和情感因素，而且动物研究的结果可能无法完全推广到人类。
2. Psychodynamic Approach | 心理动力学流派
Developed by Sigmund Freud, the psychodynamic approach emphasises the influence of the unconscious mind, instinctual drives and early childhood experiences on behaviour. Mental activity occurs outside our conscious awareness and can surface through dreams or slips of the tongue.
心理动力学流派由弗洛伊德发展而来，强调无意识心理、本能驱力和早期童年经历对行为的影响。心理活动在意识觉察之外发生，并可能通过梦境或口误浮现出来。
The personality is structured into three parts: the id (pleasure principle, demanding immediate gratification), the ego (reality principle, mediating between id and superego) and the superego (morality principle, internalised ideals). Conflict among these leads to anxiety, which the ego manages with defence mechanisms such as repression and denial.
人格结构由三部分组成：本我（快乐原则，要求即时满足）、自我（现实原则，在本我和超我之间调解）和超我（道德原则，内化的理想标准）。三者间的冲突导致焦虑，自我通过压抑和否认等防御机制来应对。
According to Freud, children progress through five psychosexual stages (oral, anal, phallic, latency, genital). Unresolved conflicts at any stage may cause fixation and later personality traits. The Oedipus complex during the phallic stage involves a boy’s desire for his mother and rivalry with his father.
弗洛伊德认为，儿童经历五个心理性发展阶段（口唇期、肛门期、性器期、潜伏期和生殖期）。任何阶段的冲突未解决都可能导致固着及日后的性格特征。性器期的俄狄浦斯情结涉及男孩对母亲的渴望及与父亲的竞争。
Freud’s case study of Little Hans provided evidence for the Oedipus complex. Hans developed a phobia of horses, which Freud interpreted as displaced fear of his father. This qualitative case study offers depth but lacks generalisability and involves subjective interpretation.
弗洛伊德对小汉斯的个案研究为俄狄浦斯情结提供了证据。小汉斯对马产生了恐惧，弗洛伊德将其解释为对父亲恐惧的转移。这种质性个案研究提供了深度，但缺乏可推广性且涉及主观解释。
The psychodynamic approach has contributed to the recognition that early experiences shape adult mental health. Nevertheless, many concepts are untestable, the approach is androcentric, and it may overemphasise sexual drives at the expense of social factors.
心理动力学流派使人们认识到早期经验塑造了成人心理健康。然而，许多概念无法验证，该流派存在男性中心倾向，并可能过度强调性驱力而忽略社会因素。
3. Humanistic Approach | 人本主义流派
The humanistic approach focuses on free will, personal growth and self-actualisation. It arose as a reaction against the deterministic views of behaviourism and psychoanalysis, claiming that people are inherently good and motivated to achieve their full potential.
人本主义流派关注自由意志、个人成长与自我实现。它作为对行为主义和精神分析决定论观点的回应而兴起，主张人性本善，人们有动力去实现自己的全部潜能。
Abraham Maslow proposed a hierarchy of needs, typically shown as a pyramid. Basic physiological and safety needs must be fulfilled before higher-level needs for love, esteem and self-actualisation can be pursued. Self-actualisation represents reaching one’s fullest potential.
亚伯拉罕·马斯洛提出了需要层次理论，通常以金字塔表示。必须先满足基本的生理和安全需要，才能追求爱、尊重和自我实现等更高层次的需要。自我实现代表着达到个人的全部潜能。
Carl Rogers emphasised that for healthy psychological development, individuals need unconditional positive regard from significant others. When acceptance is conditional (conditional positive regard), people develop conditions of worth, which lead to incongruence between the ideal self and the real self.
卡尔·罗杰斯强调，为了心理健康发展，个体需要来自重要他人的无条件积极关注。当接纳是有条件的（条件性积极关注），人们会形成价值条件，导致理想自我和真实自我之间的不一致。
Rogers developed client-centred therapy (person-centred therapy), where the therapist provides genuineness, empathy and unconditional positive regard to help clients reduce incongruence. The Q-sort technique can measure the gap between perceived self and ideal self.
罗杰斯发展了来访者中心疗法（个人中心疗法），治疗师通过真诚、共情和无条件积极关注帮助来访者减少不一致。Q 分类技术可以测量感知自我与理想自我之间的差距。
A strength is the holistic and optimistic emphasis on subjective experience. However, the approach has been criticised for being unscientific, lacking empirical evidence, and for being culturally biased—self-actualisation may reflect individualist Western values rather than universal needs.
该流派的优点在于对主观体验的整体和乐观的强调。但它也因不科学、缺乏实证证据以及存在文化偏见而受到批评——自我实现可能反映了个人主义的西方价值观而非普适需求。
4. Cognitive Approach | 认知流派
The cognitive approach argues that internal mental processes, such as memory, perception, thinking and language, can be studied scientifically. It likens the human mind to a computer, with input, processing and output, and uses models like the multi-store model of memory to explain information flow.
认知流派认为，记忆、知觉、思维和语言等内部心理过程可以进行科学研究。它把人脑比作计算机，进行输入、加工和输出，并使用诸如记忆的多储存模型等来解释信息流。
Schemas are mental frameworks that help us organise and interpret information. They are derived from past experience and can distort new information. Research on eyewitness testimony, such as Loftus and Palmer’s (1974) study, demonstrates that leading questions can influence memory recall, showing the reconstructive nature of memory.
图式是有助于我们组织和解释信息的心理框架。它们源自过往经验，可能扭曲新信息。关于目击证词的研究，例如洛夫特斯和帕尔默（1974）的实验，表明引导性问题会影响记忆提取，显示了记忆的重构性质。
Cognitive neuroscience combines cognitive psychology with brain-scanning techniques (PET, fMRI) to explore the biological basis of mental processes. This has enabled researchers to link specific cognitive functions to particular brain regions, making the approach more scientifically robust.
认知神经科学将认知心理学与脑成像技术（PET、fMRI）结合，探索心理过程的生物基础。这使得研究者能够将特定认知功能与脑区联系起来，使该流派在科学上更为严谨。
Cognitive-behavioural therapy (CBT) applies cognitive principles to treat disorders like depression by challenging irrational thoughts. Clients learn to identify, challenge and replace negative automatic thoughts with more realistic ones, linking thinking patterns to emotional well-being.
认知行为疗法（CBT）应用认知原理，通过挑战非理性思维来治疗抑郁症等障碍。来访者学习识别、挑战并用更现实的想法替代负性自动思维，将思维模式与情绪健康联系起来。
Strengths include the use of controlled laboratory experiments and objective measurements, making cognitive psychology highly scientific. Limitations involve reductionism—it can neglect the role of emotion and motivation—and the fact that its computational models may oversimplify human cognition.
优势包括使用控制实验室实验和客观测量，使认知心理学高度科学化。局限包括还原论——它可能忽视情绪和动机的作用——以及其计算模型可能过度简化了人类认知。
5. Biological Approach | 生物心理学流派
The biological approach explains behaviour through underlying physiological, genetic and evolutionary processes. It assumes that everything psychological has a biological basis and examines the role of the brain, neurotransmitters, hormones and heredity.
生物心理学流派通过潜在的生理、遗传和进化过程来解释行为。它假设所有心理现象都有其生物基础，并考察大脑、神经递质、激素和遗传的作用。
Twin and family studies are used to estimate the heritability of traits. Gottesman’s research on schizophrenia showed a higher concordance rate in monozygotic (identical) twins (around 48%) compared to dizygotic (fraternal) twins (17%), suggesting a strong genetic component, though not 100% determinism.
双生子和家庭研究用于估算特质的遗传力。戈特斯曼对精神分裂症的研究显示，同卵双生子的同病率（约48%）高于异卵双生子（17%），表明存在强烈的遗传成分，但并非100%决定论。
Brain plasticity research demonstrates that the brain can change structurally in response to experience. Maguire et al. (2000) found that London taxi drivers, who complete extensive navigation training, had increased grey matter volume in the posterior hippocampus compared to non-taxi drivers, with changes correlating with time spent on the job.
脑可塑性研究表明，大脑可以因应经验而发生结构改变。马圭尔等人（2000）发现，接受过大量导航训练的伦敦出租车司机，其海马后部灰质体积比非出租车司机更大，且这种改变与从业时间相关。
Biological therapies include drug treatments that target neurotransmitter systems, for example, SSRIs for depression increase serotonin availability. Although effective for many, they may carry side effects and are criticised for treating symptoms without addressing root causes.
生物疗法包括针对神经递质系统的药物治疗，例如用于抑郁症的SSRI类药物增加可用的血清素。尽管对许多人有效，但可能带来副作用，并被批评为只治疗症状而不解决根本原因。
The biological approach provides highly objective, measurable data through advanced scanning techniques. However, it is deterministic, implying behaviour is predetermined by biology, and can be reductionist, reducing complex social behaviours to simple neural or genetic explanations.
生物心理学流派通过先进的扫描技术提供了高度客观、可测量的数据。然而，它是决定论的，暗示行为由生物学预先决定，并且可能表现出还原论，将复杂的社会行为简化为简单的神经或遗传解释。
6. Experimental Research Methods | 实验研究方法
Experiments aim to establish cause-and-effect relationships by manipulating an independent variable (IV) and measuring its effect on a dependent variable (DV), while controlling extraneous variables. A well-formulated hypothesis, often a directional (one-tailed) or non-directional (two-tailed) prediction, guides the investigation.
实验旨在通过操纵自变量（IV）并测量它对因变量（DV）的影响，同时控制额外变量，来建立因果关系。一个表述清晰的假设，通常是有方向的（单尾）或无方向的（双尾）预测，引导着研究。
The three main experimental designs are: independent groups (different participants in each condition), repeated measures (same participants in all conditions) and matched pairs (participants are pre-matched on relevant traits and then split). Each design has strengths and weaknesses regarding participant variables and order effects.
三种主要的实验设计是：独立组设计（不同条件下使用不同被试）、重复测量设计（相同被试完成所有条件）和配对设计（被试在相关特质上预先匹配后再分组）。每种设计在控制被试变量和顺序效应方面各有优缺点。
With independent groups, there are no order effects, but participant variables can confound results unless randomly allocated. Repeated measures eliminates participant variables but risks order effects; counterbalancing is used to control this. Matched pairs reduce both concerns but require more time and a pre-test to match participants effectively.
独立组设计没有顺序效应，但被试变量可能混淆结果，除非采用随机分配。重复测量设计消除了被试变量，但可能产生顺序效应，可使用反向平衡来控制。配对设计减少了两方面的担忧，但需要更多时间并通过预测试来有效匹配被试。
Experiments are classified by setting: laboratory experiments offer high control and internal validity but may lack ecological validity; field experiments are conducted in natural settings, increasing ecological validity but with less control; natural experiments use a naturally occurring IV, with no direct manipulation; quasi-experiments involve an IV that is a pre-existing characteristic (e.g., age, gender), so cause-and-effect can only be inferred cautiously.
实验按情境分类：实验室实验控制度高，内部效度高，但可能缺乏生态效度；现场实验在自然环境中进行，提高了生态效度但控制较弱；自然实验利用自然发生的自变量，不直接操纵；准实验的自变量是预先存在的特征（如年龄、性别），因此只能谨慎地推断因果关系。
7. Non-experimental Methods | 非实验研究方法
Observational methods involve watching and recording spontaneous behaviour in either a naturalistic or controlled setting. They can be covert or overt, and participant or non-participant. Use of behavioural categories and time sampling can improve reliability, but observer bias remains a concern.
观察法涉及在自然或控制情境下观看并记录自发行为。可以是隐蔽或公开的，也可以是参与式或非参与式的。使用行为类别和时间取样可以提高信度，但观察者偏差仍是一个需要注意的问题。
Self-report techniques include questionnaires and interviews. Questionnaires can efficiently gather large amounts of data with closed questions (providing quantitative data) and open questions (providing qualitative data), but respondents may show social desirability bias. Interviews range from structured to unstructured; semi-structured interviews balance consistency with flexibility.
自陈法包括问卷和访谈。问卷通过封闭式问题（提供量化数据）和开放式问题（提供质性数据）有效收集大量信息，但回答者可能出现社会赞许性偏差。访谈从结构化到非结构化各有不同；半结构化访谈则在一致性和灵活性之间取得平衡。
Correlational analysis examines the strength and direction of a relationship between two continuous variables, summarised by a correlation coefficient (r) that ranges from -1.0 to +1.0. A positive correlation means as one variable increases, the other tends to increase; a negative correlation means one decreases as the other increases. Correlation does not imply causation.
相关分析探讨两个连续变量之间关系的强度和方向，用相关系数（r）概括，范围从 -1.0 到 +1.0。正相关表示一个变量增加，另一个也趋于增加；负相关表示一个变量增加，另一个则减少。相关关系并不意味因果关系。
Case studies provide rich, in-depth qualitative data about a single individual, group or event, often using multiple methods (interviews, observations, psychological tests). They are useful for studying rare phenomena but lack generalisability and may rely on retrospective accounts.
案例研究提供关于单一个体、群体或事件的丰富、深入的质性数据，通常采用多种方法（访谈、观察、心理测验）。它们有助于研究罕见现象，但缺乏可推广性，并可能依赖回顾性叙述。
8. Data Analysis and Ethics | 数据分析与伦理
Descriptive statistics summarise data sets: measures of central tendency (mean, median, mode) indicate typical values, while measures of dispersion (range, standard deviation) reflect variability. A small standard deviation suggests data points cluster closely around the mean.
描述统计概括数据集合：集中趋势的度量（平均数、中位数、众数）指代典型数值，而离散趋势的度量（全距、标准差）反映变异性。标准差小表明数据点紧密聚集在平均数周围。
Inferential statistics help researchers decide whether results are significant or due to chance. A significance level of p < 0.05 is commonly adopted in psychology; if the probability of obtaining the result by chance is less than 5%, the null hypothesis is rejected and the experimental hypothesis supported.
推断统计帮助研究者判断结果是显著的还是由概率所致。心理学中通常采用 p < 0.05 的显著性水平；如果结果由概率造成的可能性低于5%，则拒绝虚无假设并支持实验假设。
Ethical guidelines by the British Psychological Society (BPS) mandate that researchers must obtain informed consent, avoid deception unless justified and followed by thorough debriefing, protect participants from physical and psychological harm, ensure the right to withdraw, and maintain confidentiality of personal data.
英国心理学会（BPS）的伦理准则规定，研究者必须获得知情同意，避免欺骗（除非有充分理由并在事后进行详尽解释），保护参与者免受身心伤害，确保退出权，并对个人数据保密。
Special consideration is required for vulnerable groups and for animal research. In animal studies, the 3Rs (replacement, reduction, refinement) guide ethical practice, and the potential scientific benefit must outweigh the cost to the animals.
对易受伤害群体以及动物研究需要特别的考量。在动物研究中，3R 原则（替代、减少、优化）指导伦理实践，且潜在的科学收益必须超过动物所付出的代价。
9. Key Issues and Debates | 重要争论
The nature-nurture debate centres on whether behaviour is driven by innate biological factors (nature) or learned through environment and experience (nurture). Most psychologists now adopt an interactionist view, recognising that genetic predispositions and environmental triggers work together, as seen in stress-related disorders.
先天-后天争论围绕行为是由先天生物因素（先天）还是由环境与经验习得（后天）所驱动。如今多数心理学家采取互动论观点，承认遗传易感性与环境诱因共同作用，如在压力相关障碍中所见。
Free will versus determinism: humanistic psychology champions free will, while biological, behaviourist and psychodynamic approaches imply determinism. Soft determinism (seen in cognitive psychology) acknowledges that behaviour has causes but allows some personal choice within constraints.
自由意志与决定论：人本主义心理学拥护自由意志，而生物学、行为主义和精神分析流派意味着决定论。软决定论（见于认知心理学）承认行为有其原因，但在限制下允许一定程度的个人选择。
Reductionism simplifies behaviour to its most basic components (e.g., biological reductionism to genes and neurotransmitters, stimulus-response reductionism). Holism, in contrast, looks at the whole person in context. Both have value, but excessive reductionism can miss the richness of human experience.
还原论将行为简化为最基本的组成部分（如生物还原论归结于基因和神经递质，刺激-反应还原论）。相反，整体论在情境中看待整个个体。两者都有其价值，但过度的还原论可能错失人类经验的丰富性。
Psychology as a science debate questions whether all areas of psychology use objective, replicable, and falsifiable methods. Research methods such as controlled experiments and brain scans strengthen psychology’s scientific status, while subjective and idiographic approaches (e.g., humanistic case studies) are harder to verify.
心理学是否是一门科学的争论质疑心理学的所有领域是否都采用了客观、可重复和可证伪的方法。控制实验和脑扫描等研究方法加强了心理学的科学地位，而主观和个体化的方法（如人本主义案例研究）则较难验证。
10. Key Studies and Exam Skills | 核心研究与备考技巧
