📚 Psychology: Key Concepts, Approaches and Research Methods | 心理学：核心概念、流派与研究方法
Psychology is the scientific study of mind and behaviour. It draws on biological, cognitive, social and developmental evidence to explain how people think, feel and act. In A-level and international curricula, students explore both classic studies and contemporary debates, building the analytical skills needed to evaluate psychological theories and methods.
心理学是关于心理与行为的科学研究。它借助生物学、认知、社会和发展方面的证据来解释人们如何思考、感受和行动。在 A-level 和国际课程中，学生既要学习经典研究，也要探讨当代争议，逐步建立评价心理学理论与方法所需的分析能力。
1. Defining Psychology | 界定心理学
Psychology is often defined as the scientific study of mental processes and behaviour. Unlike everyday guesswork, psychology relies on systematic observation, measurement and replication. Its main goals are to describe, explain, predict and, where possible, change behaviour and mental experience.
心理学通常被定义为对心理过程和行为的科学研究。与日常猜测不同，心理学依赖系统的观察、测量和可重复验证。其主要目标是描述、解释、预测并在可能的情况下改变行为和心理体验。
Psychologists explain behaviour at biological, cognitive and social levels. For example, aggression may be understood through brain circuits, thought patterns or group norms. This multi-level perspective makes psychology both diverse and integrative.
心理学家从生物学、认知和社会层面解释行为。例如，攻击行为可以通过大脑回路、思维模式或群体规范来理解。这种多层次的视角使心理学既多元又具有整合性。
2. Major Approaches in Psychology | 心理学主要流派
The main approaches include behaviourism, cognitive psychology, biological psychology, psychodynamic theory and humanism. Each approach makes distinct assumptions about the causes of behaviour and uses different research methods.
主要流派包括行为主义、认知心理学、生物心理学、心理动力学理论和人本主义。每个流派对行为成因的假设不同，并采用不同的研究方法。
- Behaviourist approach: Behaviour is learned through classical and operant conditioning; research uses controlled lab experiments.
行为主义流派：行为通过经典条件作用和操作性条件作用习得；研究采用控制性实验室实验。 - Cognitive approach: Internal mental processes such as memory and perception mediate between stimulus and response.
认知流派：记忆和感知等内部心理过程在刺激与反应之间起中介作用。 - Biological approach: Genes, brain structures and neurochemistry shape behaviour; twin studies and brain scans are common methods.
生物流派：基因、大脑结构和神经化学塑造行为；双生子研究和脑成像扫描是常用方法。 - Psychodynamic approach: Unconscious drives and early childhood experiences influence adult personality; case studies are often used.
心理动力学流派：无意识驱力和早期童年经历影响成年人格；常采用案例研究。 - Humanistic approach: People have free will and strive for growth and self-actualisation; qualitative interviews are preferred.
人本主义流派：人具有自由意志，并追求成长和自我实现；偏好质性访谈。
Each approach contributes valuable insights, but none fully explains all behaviour. Therefore, many psychologists adopt an eclectic or biopsychosocial framework that combines biological, psychological and social factors.
每种流派都提供了有价值的见解，但没有一种能完全解释所有行为。因此，许多心理学家采用折中或生物心理社会框架，将生物学、心理学和社会因素结合起来。
3. Biological Foundations of Behaviour | 行为的生物学基础
Biological psychology examines how the nervous system and hormones influence behaviour. Neurons transmit electrical and chemical signals; neurotransmitters such as serotonin and dopamine affect mood, motivation and arousal. The endocrine system releases hormones like cortisol during stress, triggering the fight-or-flight response.
生物心理学研究神经系统和激素如何影响行为。神经元传递电信号和化学信号；血清素和多巴胺等神经递质会影响情绪、动机和唤醒水平。内分泌系统在应激时释放皮质醇等激素，引发战斗或逃跑反应。
Brain plasticity means that neural connections can change with experience, which challenges strict genetic determinism. Twin and adoption studies help estimate the heritability of traits such as intelligence and temperament, but they also show that environments matter.
大脑可塑性意味着神经连接可随经验改变，这对严格的基因决定论提出了挑战。双生子和收养研究有助于估计智力和气质等特质的遗传度，但它们也表明环境同样重要。
4. Cognitive Psychology and Memory | 认知心理学与记忆
The cognitive approach studies internal mental processes such as perception, attention, language and memory. The multi-store model proposes separate sensory, short-term and long-term stores, while the working memory model focuses on active processing of verbal and visual information.
认知流派研究感知、注意、语言和记忆等内部心理过程。多储存模型提出感觉记忆、短时记忆和长时记忆是分离的储存系统，而工作记忆模型则侧重对言语和视觉信息进行主动加工。
Memory research distinguishes between encoding, storage and retrieval. Forgetting may occur because of decay, interference or retrieval failure, which has practical implications for revision and eyewitness testimony. Research by Loftus shows that leading questions can distort memory, so memory is reconstructive rather than a passive recording.
记忆研究区分编码、储存和提取。遗忘可能由衰退、干扰或提取失败引起，这对复习策略和目击者证词具有实际意义。洛夫特斯的研究表明，引导性问题会扭曲记忆，因此记忆是重构性的而非被动记录。
5. Social Influence and Conformity | 社会影响与从众
Social psychology investigates how individuals are affected by the real or imagined presence of others. Classic studies by Asch, Milgram and Zimbardo reveal the power of conformity, obedience and social roles. These experiments show that ordinary people can behave in unexpected ways under situational pressure.
社会心理学研究个体如何受到他人真实或想象存在的影响。阿施、米尔格拉姆和津巴多的经典研究揭示了从众、服从和社会角色的巨大力量。这些实验表明，普通人在情境压力下也可能表现出意想不到的行为。
Conformity can be normative or informational, while obedience often depends on authority, proximity and personal responsibility. Situational factors can override individual disposition. Minority influence can create social change through consistency, commitment and flexibility, as seen in civil rights movements.
从众可分为规范性和信息性从众，而服从往往取决于权威、接近程度和个人责任感。情境因素能够压倒个体倾向。少数人影响可以通过一致性、投入和灵活性带来社会变革，如民权运动所示。
6. Developmental Psychology and Attachment | 发展心理学与依恋
Developmental psychology studies changes across the lifespan, with attachment theory being a central topic. Bowlby argued that infants have an innate need to form a strong emotional bond with a caregiver. This monotropic bond provides a secure base for exploration and later relationships.
发展心理学研究个体一生的变化，依恋理论是核心主题。鲍尔比认为婴儿天生需要与照料者建立强烈的情感纽带。这种单亲依恋关系为探索活动和日后人际关系提供了安全基地。
Ainsworth’s Strange Situation identified secure, insecure-avoidant and insecure-resistant attachment styles. These patterns may be influenced by parental sensitivity and cultural norms. Bowlby’s maternal deprivation hypothesis suggests that prolonged early separation can harm emotional and intellectual development, although later research shows some resilience.
安斯沃思的陌生情境实验识别出安全型、不安全回避型和不安全反抗型依恋类型。这些模式可能受到父母敏感性和文化规范的影响。鲍尔比的母爱剥夺假说认为，早期长期分离会损害情绪和智力发展，尽管后来的研究表明儿童具有一定的复原力。
7. Psychopathology and Treatment | 心理病理学与治疗
Psychopathology examines the classification, explanation and treatment of mental disorders. Definitions of abnormality may rely on statistical rarity, deviation from social norms, failure to function adequately or deviation from ideal mental health. Each definition has strengths and culturally specific limitations.
心理病理学研究心理障碍的分类、解释和治疗。异常的定义可能依据统计罕见性、偏离社会规范、功能受损或偏离理想心理健康标准。每种定义都有优点，也存在文化特定的局限。
Biological treatments include drug therapy, while psychological therapies include cognitive-behavioural therapy and systematic desensitisation. CBT aims to identify and change negative automatic thoughts and maladaptive behaviours, often through structured sessions and homework tasks. Evaluations consider effectiveness, side effects and ethical concerns.
生物治疗包括药物治疗，心理治疗则包括认知行为疗法和系统脱敏法。认知行为疗法旨在识别并改变负性自动思维和适应不良行为，通常通过结构化会谈和家庭作业实现。评价时会考虑有效性、副作用和伦理问题。
8. Research Methods in Psychology | 心理学研究方法
Psychological research uses experiments, correlational studies, observations, questionnaires, interviews and case studies. Experiments allow causal conclusions, whereas correlations only show relationships. Observations can be naturalistic or controlled, and questionnaires gather large amounts of self-report data efficiently.
心理学研究使用实验、相关研究、观察、问卷、访谈和案例研究。实验可以做因果推论，而相关只能说明变量之间存在关系。观察可以是自然观察或控制观察，问卷则能高效地收集大量自我报告数据。
Key methodological concepts include independent and dependent variables, controls, random sampling, reliability and validity. Design choices such as independent groups, repeated measures or matched pairs affect control of participant variables and order effects. A robust study minimises bias and can be replicated.
关键方法论概念包括自变量和因变量、控制、随机抽样、信度和效度。独立组、重复测量或配对组等设计选择会影响参与者变量的控制以及顺序效应。一项严谨的研究应尽量减少偏差并能被重复验证。
9. Ethical Issues in Psychological Research | 心理学研究中的伦理问题
Ethical guidelines require informed consent, avoidance of deception where possible, confidentiality, right to withdraw and protection from harm. Participants must be debriefed after the study. Ethics committees review proposals to ensure that the benefits of research outweigh potential risks.
伦理准则要求知情同意、尽可能避免欺骗、保密、有权退出以及保护参与者免受伤害。研究结束后必须向参与者进行事后说明。伦理委员会审查研究方案，以确保研究的收益大于潜在风险。
Classic studies such as Milgram’s obedience experiment are often criticised because participants experienced distress and were deceived. This has led to stricter ethical review in modern psychology. The use of animals in research is governed by the 3Rs: replacement, reduction and refinement.
米尔格拉姆服从实验等经典研究常被批评，因为参与者经历了痛苦并且受到欺骗。这促使现代心理学建立了更严格的伦理审查机制。动物研究受 3R 原则约束：替代、减少和优化。
10. Debates and Exam Skills | 争议与备考技巧
Key debates include nature versus nurture, free will versus determinism, reductionism versus holism, and idiographic versus nomothetic approaches. These debates help students evaluate competing explanations and recognise the complexity of human behaviour.
重要争议包括先天与后天、自由意志与决定论、还原论与整体论，以及个案研究与通则研究。这些争议有助于学生评价不同解释，并认识到人类行为的复杂性。
For exam success, define terms precisely, use studies as evidence, and always evaluate strengths and limitations. Use the PEE structure (point, evidence, evaluation) to build balanced arguments and include examples from studies such as Asch, Bandura or Bowlby. Link your points back to the question and consider alternative interpretations.
为了在考试中取得好成绩，要准确定义术语，引用研究作为证据，并始终评价优点和局限。使用 PEE 结构（观点、证据、评价）构建均衡论点，并引用阿施、班杜拉或鲍尔比等研究作为例证。将论点与题目联系起来，并考虑替代解释。
