1. Research Methods: The Basics | 研究方法：基础
Psychological research relies on four main types of investigation: experiments, observations, self‑reports, and correlations. In an experiment, the researcher manipulates an independent variable (IV) and measures its effect on a dependent variable (DV) while controlling extraneous variables.
心理学研究主要依赖四种调查类型：实验、观察、自陈报告和相关研究。在实验中，研究者操纵自变量（IV），测量其对因变量（DV）的影响，同时控制额外变量。
Observations can be naturalistic, controlled, participant, or non‑participant. They generate rich qualitative data but are prone to observer bias and lack of control over confounding variables.
观察法可以是自然观察、控制观察、参与式或非参与式。它们能产生丰富的质性资料，但容易出现观察者偏差且难以控制混淆变量。
Self‑report techniques include questionnaires and interviews. They allow direct access to thoughts and feelings but may suffer from social desirability bias and misinterpretation of questions.
自陈技术包括问卷和访谈。它们可以直接获取想法和感受，但可能遭受社会赞许偏差和题目误解的影响。
Correlational research measures the relationship between two variables without manipulation. A correlation coefficient (r) ranges from -1 to +1, indicating strength and direction, yet cannot establish causation.
相关研究在不进行操纵的情况下测量两个变量之间的关系。相关系数（r）的范围从 -1 到 +1，指示强度和方向，但无法确立因果关系。
2. Biological Approach: Brain and Behaviour | 生物学方法：大脑与行为
The biological approach assumes that all thoughts, feelings, and behaviours have a physical basis. Key explanations focus on genetics, brain structure, and neurochemistry.
生物学方法假设所有思想、情感和行为都有其生理基础。主要解释集中在遗传、大脑结构和神经化学上。
Twin and adoption studies provide evidence for the heritability of traits such as intelligence and schizophrenia. Concordance rates are significantly higher in monozygotic (MZ) twins than dizygotic (DZ) twins.
双生子和收养研究为智力、精神分裂症等特质的遗传力提供了证据。同卵双生子的同病率显著高于异卵双生子。
Brain imaging techniques like MRI and PET scans have linked specific regions to functions: the hippocampus is crucial for spatial memory, as shown in Maguire et al.'s taxi driver study, where posterior hippocampal volume increased with navigation experience.
MRI 和 PET 等脑成像技术已将特定区域与功能联系起来：海马体对空间记忆至关重要，如 Maguire 等人的出租车司机研究所显示，后海马体体积随着导航经验的增加而增大。
Neurotransmitters such as serotonin and dopamine influence mood and motivation. The approach is highly scientific and falsifiable, yet reductionist as it often simplifies complex human experiences to biological mechanisms.
血清素和多巴胺等神经递质影响情绪和动机。该流派高度科学、可证伪，但因其常将复杂的人类体验简化为生物机制而带有还原论色彩。
3. Behavioural Approach: Conditioning and Learning | 行为主义方法：条件反射与学习
The behavioural approach focuses exclusively on observable behaviour and rejects mental processes as suitable subject matter. Behaviour is understood as a product of environmental conditioning.
行为主义方法只关注可观察的行为，并拒绝将心理过程作为恰当的研究对象。行为被理解为环境条件作用的产物。
Classical conditioning, demonstrated by Pavlov's dogs, explains how a neutral stimulus can come to elicit a response when repeatedly paired with an unconditioned stimulus. The response then becomes a conditioned response.
经典条件反射由巴甫洛夫的狗实验展示，解释了一个中性刺激与无条件刺激反复配对后，如何引发反应，该反应随后成为条件反应。
Operant conditioning, proposed by Skinner, states that behaviour is shaped by consequences. Reinforcement (positive or negative) increases behaviour, while punishment decreases it. Schedules of reinforcement affect the rate and persistence of learning.
斯金纳提出的操作条件反射指出，行为由其后果塑造。强化（正强化或负强化）增加行为，惩罚减少行为。强化程序影响学习的速度和持久性。
Social learning theory, developed by Bandura, adds a cognitive dimension by emphasising observational learning and vicarious reinforcement. The Bobo doll study showed children imitating aggressive adult models, especially when the model was rewarded.
班杜拉发展的社会学习理论通过强调观察学习和替代性强化，增添了认知维度。波波玩偶研究显示儿童会模仿攻击性的成人榜样，当榜样受到奖励时模仿更为明显。
4. Cognitive Approach: Memory and Thought Processes | 认知方法：记忆与思维过程
The cognitive approach likens the mind to an information processor, studying internal mental processes such as perception, memory, and problem‑solving. It uses experimental methods and often constructs theoretical models.
认知方法将心智比作信息加工器，研究感知、记忆和问题解决等内部心理过程。它采用实验方法，并常常构建理论模型。
The multi‑ model (Atkinson & Shiffrin) proposes three separate memory stores: sensory register, short‑term memory (STM), and long‑ res via attention and rehearsal, with STM having a limited capacity of about 7 ± 2 chunks.
多贮存模型（阿特金森和谢夫林）提出了三个独立的记忆贮存库：感觉登记器、短时记忆和长时记忆。信息通过注意和复述在贮存库之间转移，短时记忆的容量有限，约为 7 ± 2 个组块。
Schemas are mental frameworks that help organise and interpret information. They enable rapid processing but can lead to distortions in memory, as evidenced by Bartlett's 'War of the Ghosts' study where participants reconstructed the story to fit their own cultural schemas.
图式是帮助组织和解释信息的心理框架。它们能够快速加工信息，但可能导致记忆扭曲，正如巴特利特的“幽灵之战”研究所证明的，参与者根据自己的文化图式重构了故事。
The cognitive approach has high internal validity from controlled experiments, but critics argue it ignores emotion and biological influences, and the computer analogy may oversimplify human cognition.
认知方法通过控制实验获得了较高的内部效度，但批评者认为它忽视了情绪和生物影响，而且计算机类比可能过度简化了人类认知。
5. Psychodynamic Approach: Unconscious Mind and Childhood | 心理动力学方法：潜意识与童年
Initiated by Sigmund Freud, the psychodynamic approach emphasises the role of the unconscious mind, early childhood experiences, and innate drives in shaping personality and behaviour.
由弗洛伊德开创的心理动力学方法强调潜意识、早期童年经历和先天驱力在塑造人格与行为中的作用。
The mind is structured into three parts: the id (pleasure principle), ego (reality principle), and superego (morality principle). Conflict among these structures creates anxiety, which the ego manages through defence mechanisms.
心智结构分为三个部分：本我（快乐原则）、自我（现实原则）和超我（道德原则）。这些结构之间的冲突会产生焦虑，自我通过防御机制加以管理。
Common defence mechanisms include repression (pushing threatening memories into the unconscious), denial, and displacement. They operate unconsciously and temporarily reduce anxiety but can lead to maladaptive behaviour.
常见的防御机制包括压抑（将威胁性记忆推入潜意识）、否认和转移。它们在潜意识中运作，暂时缓解焦虑，但可能导致适应不良行为。
Freud proposed five psychosexual stages (oral, anal, phallic, latency, genital). Fixation at a stage due to under‑ or over‑gratification supposedly influences adult personality, e.g., anal retentiveness from harsh toilet training.
弗洛伊德提出五个心理性欲发展阶段（口唇期、肛门期、性器期、潜伏期、生殖期）。在某一阶段因满足不足或过度而固着，可能影响成人人格，例如严厉的如厕训练导致肛门滞留型人格。
The approach uses case studies like Little Hans, providing rich qualitative data, but it is criticised for being unfalsifiable, deterministic, and based on a small, unrepresentative sample.
该流派使用小汉斯等个案研究，提供了丰富的质性资料，但被批评为不可证伪、具有决定论色彩，并且基于少量且不具代表性的样本。
6. Humanistic Approach: Self‑Actualisation and Free Will | 人本主义方法：自我实现与自由意志
The humanistic approach focuses on the whole person, free will, and the innate drive to achieve one's full potential. It emerged as a reaction against the deterministic outlooks of behaviourism and psychoanalysis.
人本主义方法关注完整的人、自由意志以及实现自身潜能的内驱力。它作为对行为主义和精神分析决定论世界观的反动而兴起。
Maslow's hierarchy of needs arranges human motivations in a pyramid: basic physiological needs must be satisfied before safety, love/belonging, esteem, and finally self‑actualisation can be pursued. Self‑actualised individuals are creative, accepting, and peak‑experience‑oriented.
马斯洛的需求层次将人类动机排列成金字塔：必须先满足基本的生理需要，才能追求安全、爱与归属、尊重，最终达到自我实现。自我实现者富有创造力、接纳性，并追求高峰体验。
Carl Rogers emphasised the self‑concept and the importance of unconditional positive regard from others. When a person experiences incongruence between their actual self and ideal self, psychological distress occurs. Client‑centred therapy aims to reduce this gap through empathy, genuineness, and unconditional positive regard.
卡尔·罗杰斯强调自我概念以及来自他人的无条件积极关注的重要性。当一个人的真实自我与理想自我之间出现不协调，就会产生心理困扰。来访者中心疗法旨在通过共情、真诚和无条件积极关注来缩小这一差距。
The humanistic approach is holistic and values subjective experience, yet concepts like self‑actualisation are difficult to measure empirically. It may also underestimate the influence of biological and social constraints.
人本主义方法是整体性的，重视主观体验，但自我实现等概念难以用实证测量。它可能也低估了生物和社会约束的影响。
7. Ethical Issues and Guidelines in Psychology | 心理学中的伦理问题与准则
All psychological research must adhere to ethical principles designed to protect participants. The British Psychological Society (BPS) Code of Ethics outlines four core principles: respect, competence, responsibility, and integrity.
所有心理学研究都必须遵守旨在保护参与者的伦理原则。英国心理学会伦理守则概述了四个核心原则：尊重、胜任、责任和诚信。
Informed consent requires that participants know the aims, procedures, and their right to withdraw before agreeing to take part. When full disclosure is not possible, researchers must obtain presumptive consent or debrief participants thoroughly afterwards.
知情同意要求参与者在同意参加前了解研究目的、程序及其退出权。当无法完全告知时，研究者必须获取预先同意，或在事后对参与者进行充分解释。
Deception should be avoided, but if used, it must be justified by significant scientific value and lack of alternatives. A cost‑benefit analysis is conducted, and participants must be debriefed as soon as possible to explain the true nature of the study.
应当避免欺骗，但如果使用，必须由重大的科学价值和无其他方法可替代来证明其合理性。需要进行成本效益分析，并且必须尽快对参与者进行事后解释，说明研究的真实性质。
Confidentiality ensures that personal data is protected and not disclosed. Participants are typically referred to by numbers or pseudonyms. They have the right to withdraw their data at any point during and after the research, up to publication.
保密确保个人数据得到保护而不被泄露。通常用编号或化名指代参与者。他们有权在研究期间及之后、直至发表前的任何时刻撤回自己的数据。
Protection from harm means participants should not experience psychological or physical harm greater than that encountered in everyday life. Researchers must provide support if unintended distress occurs.
免受伤害意味着参与者不应遭受超过日常生活中所遇程度的心理或身体伤害。若发生意外困扰，研究者必须提供支持。
8. Data Analysis: Descriptive Statistics and Graphs | 数据分析：描述性统计与图表
he features of a dataset. Measures of central tendency indicate the typical score: mean (x̄), median, and mode. The mean is calculated as x̄ = Σx / n, but it is sensitive to extreme scores.
描述性统计总结和描述数据集的特征。集中趋势量数指示典型分数：均值（x̄）、中位数和众数。均值计算为 x̄ = Σx / n，但它对极端分数敏感。
the highest and lowest values. Standard deviation (SD) is more informative: SD = √(Σ(x - x̄)² / n). A low SD indicates scores are clustered near the mean.
离散程度量数反映数据的散布情况。全距是最高值与最低值之间的差。标准差更具信息量：SD = √(Σ(x - x̄)² / n)。低标准差表明分数集中在均值附近。
Here is a summary of common descriptive measures:
以下是常见描述性指标的总结：
| Measure / 量数 | Definition / 定义 | Sensitivity / 敏感性 |
|---|---|---|
| Mean / 均值 | Arithmetic average / 算术平均值 | Influenced by outliers / 受离群值影响 |
| Median / 中位数 | Middle value when ordered / 排序后的中间值 | Robust against outliers / 对离群值稳健 |
| Mode / 众数 | Most frequent value / 最频繁出现的值 | Can be unaffected by extreme scores / 可能不受极端分数影响 |
| Range / 全距 | Highest minus lowest / 最大减最小 | Affected by a single outlier / 受单个离群值影响 |
| Standard deviation / 标准差 | Average deviation from mean / 偏离均值的平均程度 | Uses every data point / 使用每个数据点 |
Graphs help visualise data distributions. Bar charts present discrete (categorical) data, histograms display continuous data with touching bars, and scattergrams show the relationship between two variables. The normal distribution is a bell‑shaped curve where mean, median, and mode coincide at the centre.
图表有助于直观呈现数据分布。条形图展示离散（分类）数据，直方图以相邻长条显示连续数据，散点图展示两个变量之间的关系。正态分布是一条钟形曲线，均值、中位数和众数重合于中央。
9. Stress: Causes, Effects, and Management | 压力：原因、影响与管理
Stress is a pattern of physiological and psychological responses to perceived demands that exceed coping resources. The transactional model (Lazarus & Folkman) views stress as an interaction between the individual's appraisal and the environment.
压力是对超出应对资源的外部要求所产生的一系列生理和心理反应。交易模型（拉扎勒斯和福克曼）将压力视为个体评估与环境之间的相互作用。
Selye's General Adaptation Syndrome (GAS) describes a three‑stage bodily response: alarm (activation of the sympathetic nervous system and HPA axis), resistance (continued high arousal with adaptation), and exhaustion (depletion of resources, leading to illness).
塞利的一般适应综合征（GAS）描述了一个三阶段的躯体反应：警戒期（交感神经系统和 HPA 轴激活）、抵抗期（持续高唤醒并适应）和衰竭期（资源耗尽，导致疾病）。
Life changes, as measured by the Social Readjustment Rating Scale (Holmes & Rahe), accumulate stress and correlate with physical illness. Daily hassles, however, have been found to be stronger predictors of stress‑related health problems than major life events.
生活事件，如社会再适应评定量表（霍姆斯和拉赫）所测量的，会累积压力并与躯体疾病相关。然而，日常烦扰被发现比重大生活事件更能预测与压力相关的健康问题。
Stress management techniques include biological methods (e.g., benzodiazepines enhancing GABA activity) and psychological methods such as cognitive‑behavioural therapy (CBT) and mindfulness‑based stress reduction. Social support also buffers the negative effects of stress on health.
压力管理方法包括生物学方法（如苯二氮䓬类药物增强 GABA 活性）和心理方法，如认知行为疗法（CBT）和正念减压法。社会支持也能缓冲压力对健康的负面影响。
10. Behavioural Addictions: Gambling and Gaming | 行为成瘾：赌博与游戏成瘾
Behavioural addictions involve compulsive engagement in rewarding non‑substance‑related behaviours. Gambling disorder and internet gaming disorder are key examples examined in CCEA Health and Wellbeing topics.
行为成瘾涉及对具有奖赏性但非物质的某种行为的强迫性投入。赌博障碍和网络游戏障碍是 CCEA 健康与幸福课题中考察的关键实例。
Gambling addiction is characterised by loss of control, chasing losses, continued gambling despite negative consequences, and tolerance (needing to gamble with increasing amounts). Cognitive biases such as the illusion of control and the gambler's fallacy fuel persistent gambling.
赌博成瘾的特征包括失控、追回损失、不顾负面后果继续赌博以及耐受性（需要加大赌注）。控制幻觉和赌徒谬误等认知偏差助长了持续赌博。
Learning theory explains gambling through partial reinforcement and the variable‑ratio schedule, which makes extinction extremely slow. Near‑misses also activate dopamine reward pathways, mimicking a win and encouraging repeated play.
学习理论通过部分强化和变动比率程序来解释赌博，这使得消退极为缓慢。差一点赢也会激活多巴胺奖赏通路，模拟赢的体验并鼓励重复下注。
Internet gaming disorder involves persistent gaming to the extent that it impairs daily functioning. Risk factors include low self‑esteem, poor impulse control, and the structural characteristics of games (easy access, reward loops, and social anonymity) that make them inherently addictive.
网络游戏障碍指持续沉迷游戏，以致损害日常功能。风险因素包括低自尊、冲动控制差，以及游戏本身的结构特征（易获得、奖励循环和社交匿名性），这些使其具有内在成瘾性。
Biopsychosocial models suggest that genetic predisposition, dopamine dysregulation, environmental stressors, and maladaptive thought patterns together contribute to the development and maintenance of behavioural addictions. Treatment often combines CBT, motivational interviewing, and in some cases pharmacological support.
生物心理社会模型表明，遗传易感性、多巴胺失调、环境压力源以及适应不良的思维模式共同促成了行为成瘾的发展和维持。治疗通常结合 CBT、动机性访谈，并在某些情况下辅以药物支持。
