1. Social Influence | 社会影响

Social influence examines how an individual’s thoughts, feelings, and behaviours are affected by the presence of others. Key areas include conformity (Asch, 1951, 1955), obedience to authority (Milgram, 1963), resistance to social influence, minority influence (Moscovici et al., 1969), and social change. Asch found that about 37% of responses conformed under group pressure, with variations in group size, unanimity, and task difficulty reducing conformity. Milgram’s baseline study revealed that 65% of participants administered the maximum 450-volt shock, demonstrating immense obedience to an authority figure. Explanations for obedience include the agentic state and legitimacy of authority. Furthermore, Adorno’s authoritarian personality suggests that harsh parenting leads to a dispositional readiness to obey. Social influence processes also explain societal shifts, such as through the snowball effect of minority influence leading to majority conversion.

社会影响探讨个体的思维、情感和行为如何受到他人存在的影响。关键领域包括从众（Asch, 1951, 1955）、对权威的服从（Milgram, 1963）、对社会影响的抵制、少数派影响（Moscovici 等，1969）和社会变革。Asch发现，在群体压力下，大约37%的回答是从众的，而群体规模、一致性和任务难度等因素会降低从众程度。Milgram的基线研究显示，65%的参与者施加了最高450伏的电击，表现出对权威人物极大的服从。对服从的解释包括代理状态和权威的合法性。此外，Adorno的权威人格理论指出，严苛的教养方式会导致一种服从的倾向性。社会影响过程也解释了社会转变，例如通过少数派影响的滚雪球效应最终导致多数派的转化。

2. Memory | 记忆

The study of memory covers models of memory, explanations for forgetting, and factors affecting the accuracy of eyewitness testimony. The multi-store model (Atkinson & Shiffrin, 1968) proposes three separate stores: sensory register, short-term memory (STM), and long-term memory (LTM), distinguished by capacity, duration, and coding. The working memory model (Baddeley & Hitch, 1974) challenges the unitary STM, introducing the central executive, phonological loop, visuo-spatial sketchpad, and episodic buffer. Forgetting is explained through interference theory (proactive and retroactive) and retrieval failure due to absence of cues. Eyewitness testimony can be distorted by misleading information and anxiety; the cognitive interview is designed to enhance recall accuracy.

记忆研究涵盖记忆模型、遗忘的解释以及影响目击证词准确性的因素。多存储模型（Atkinson & Shiffrin, 1968）提出三个独立存储：感觉登记、短时记忆和长时记忆，其区别在于容量、持续时间和编码。工作记忆模型（Baddeley & Hitch, 1974）对单一短时记忆提出挑战，引入了中央执行器、语音回路、视觉空间画板和情景缓冲器。遗忘可通过干扰理论（前摄和倒摄）及因缺乏线索导致的提取失败来解释。目击证词可能受到误导信息和焦虑的扭曲；认知访谈旨在提升回忆的准确性。

3. Attachment | 依恋

Attachment describes the deep emotional bond between an infant and caregiver, affecting social and emotional development. Caregiver-infant interactions include reciprocity and interactional synchrony (Meltzoff & Moore, 1977). Schaffer and Emerson (1964) identified stages of attachment: asocial, indiscriminate, specific, and multiple attachments. Animal studies, such as Lorenz’s goslings and Harlow’s rhesus monkeys, highlight the roles of imprinting and contact comfort. Ainsworth’s Strange Situation classified attachment types: secure (66%), insecure-avoidant (22%), and insecure-resistant (12%), with cultural variations. Bowlby’s maternal deprivation hypothesis and the 44 thieves study link early disruption to later emotional maladjustment. The effects of institutionalisation (Rutter et al., Romanian orphans) demonstrate lasting cognitive and social difficulties but also the potential for recovery with early adoption. Attachment influences internal working models that shape future relationships.

依恋描述婴儿与照料者之间深刻的情感纽带，影响着社会性和情绪发展。照料者-婴儿互动包括互动同步性和轮流互动（Meltzoff & Moore, 1977）。Schaffer和Emerson（1964）确定了依恋阶段：无社会性、无差别、特定依恋和多重依恋。动物研究如Lorenz的幼鹅和Harlow的恒河猴，突出了印记和接触安慰的作用。Ainsworth的陌生情境将依恋类型分为：安全型（66%）、不安全-回避型（22%）和不安全-反抗型（12%），并存在文化差异。Bowlby的母爱剥夺假说及44个小偷研究将早期中断与后期情绪失调联系起来。强制收容的影响（Rutter等，罗马尼亚孤儿）表明存在持久的认知和社交困难，但也揭示了早期被收养有恢复的可能。依恋影响内部工作模式，塑造未来的关系。

4. Psychopathology | 心理病理学

Psychopathology involves the study of mental disorders, focusing on definitions of abnormality, and characteristics, explanations, and treatments for phobias, depression, and obsessive-compulsive disorder (OCD). Abnormality can be defined through statistical infrequency, deviation from social norms, failure to function adequately, and deviation from ideal mental health. Phobias are characterised by excessive fear and avoidance; the two-process model (Mowrer) explains acquisition through classical conditioning and maintenance through operant conditioning. Systematic desensitisation and flooding are behaviourist treatments based on counterconditioning. Depression’s cognitive characteristics involve negative schemas and irrational beliefs; Beck’s negative triad and Ellis’s ABC model are central. Cognitive-behavioural therapy (CBT), including REBT, challenges irrational thoughts. OCD is associated with intrusive thoughts and compulsive behaviours. The biological explanation involves genetic vulnerability (candidate genes like SERT and COMT) and neural abnormalities (orbitofrontal cortex, basal ganglia, serotonin and dopamine dysregulation). Drug therapy using SSRIs increases serotonin levels.

心理病理学研究精神障碍，重点是异常定义，以及恐惧症、抑郁症和强迫症（OCD）的特征、解释和治疗。异常可通过统计稀少性、偏离社会规范、功能失调和偏离理想心理健康来定义。恐惧症以过度恐惧和回避为特征；两过程模型（Mowrer）解释其通过经典条件作用获得，并通过操作性条件作用维持。系统脱敏和冲击疗法是基于反条件作用的行为主义治疗。抑郁症的认知特征涉及负性图式和非理性信念；Beck的负性认知三合一和Ellis的ABC模型至关重要。认知行为疗法（包括理性情绪行为疗法）挑战非理性思维。OCD与侵入性思想和强迫行为相关。生物学解释涉及遗传易感性（候选基因如SERT和COMT）和神经异常（眶额皮层、基底神经节、血清素和多巴胺失调）。使用SSRIs的药物疗法可以提升血清素水平。

5. Approaches in Psychology | 心理学流派

The major approaches provide distinct perspectives on human behaviour. The behaviourist approach focuses on observable behaviour, classical conditioning (Pavlov’s dogs) and operant conditioning (Skinner’s rats and pigeons), rejecting mental processes as unscientific. Social learning theory (Bandura) adds cognitive mediational processes and vicarious reinforcement, demonstrated in the Bobo doll studies. The cognitive approach investigates internal mental processes like memory and perception, using models (e.g., information processing approach) and cognitive neuroscience. The biological approach emphasises genetic inheritance, neurochemistry, and brain structures, with twin studies revealing heritability of traits. The psychodynamic approach (Freud) proposes the unconscious mind, tripartite personality (id, ego, superego), psychosexual stages, and defence mechanisms. The humanistic approach (Rogers, Maslow) stresses free will, self-actualisation, and conditions of worth, advocating person-centred therapy.

主要流派为人类行为提供了独到视角。行为主义流派关注可观察行为，研究经典条件作用（巴甫洛夫的狗）和操作性条件作用（斯金纳的老鼠与鸽子），反对将心理过程作为非科学的对象。社会学习理论（班杜拉）增加了认知中介过程和替代强化，通过波波玩偶研究加以证明。认知流派探究记忆、知觉等内在心理过程，使用模型（如信息加工取向）和认知神经科学。生物学流派强调遗传、神经化学和脑结构，双胞胎研究揭示了特质的遗传率。心理动力学流派（弗洛伊德）提出无意识心理、三层人格结构（本我、自我、超我）、性心理阶段以及防御机制。人本主义流派（罗杰斯、马斯洛）强调自由意志、自我实现和价值条件，倡导以当事人为中心的治疗。

6. Biopsychology | 生物心理学

Biopsychology bridges psychology and biology, examining the nervous and endocrine systems, fight or flight response, brain plasticity, and biological rhythms. The nervous system is divided into central and peripheral systems; the peripheral includes the somatic and autonomic (sympathetic and parasympathetic) nervous systems. Neurons transmit electrical impulses across synapses through neurotransmitters. The endocrine system uses hormones such as adrenaline and cortisol, being slower but more widespread in effect. The fight or flight response is a coordinated autonomic and endocrine reaction to acute stress, including increased heart rate and glucose release. Brain plasticity refers to the brain’s ability to change structurally and functionally due to experience; Maguire et al. (2000) found larger posterior hippocampi in London taxi drivers, supporting plasticity and functional recovery after trauma. Circadian, infradian, and ultradian rhythms govern sleep-wake cycles and other bodily functions, regulated by endogenous pacemakers and exogenous zeitgebers.

生物心理学连接心理学和生物学，研究神经系统和内分泌系统、战斗或逃跑反应、大脑可塑性以及生物节律。神经系统分为中枢和外周系统；外周系统包括躯体神经系统和自主神经系统（交感与副交感）。神经元通过神经递质跨越突触传递电冲动。内分泌系统利用肾上腺素和皮质醇等激素，其作用较慢但影响更为广泛。战斗或逃跑反应是身体对急性压力产生的自主神经和内分泌协调反应，包括心率和葡萄糖释放增加。大脑可塑性指大脑因经验而发生结构和功能改变的能力；Maguire等（2000）发现伦敦出租车司机的后海马体体积更大，支持了可塑性和创伤后的功能恢复。昼夜节律、周内节律和超昼夜节律调控睡眠-觉醒周期等身体功能，受内源性起搏器和外源性授时因子的调节。

7. Research Methods | 研究方法

Research methods form the bedrock of psychological investigation, covering experimental design, data analysis, and ethical considerations. Aims and hypotheses (directional and non-directional) guide studies. Independent groups, repeated measures, and matched pairs are common experimental designs, each with strengths and limitations. Variables include independent, dependent, and confounding (including demand characteristics and investigator effects). Sampling techniques range from random and stratified to opportunity and volunteer sampling. Researchers use experiments (laboratory, field, natural, quasi), observations (naturalistic, controlled, covert, overt, participant, non-participant), self-report techniques (questionnaires, interviews), and correlations. Data analysis involves descriptive statistics (mean, median, mode, range, standard deviation) and inferential statistics (choosing appropriate tests like Sign test, Chi-square, Mann-Whitney, Wilcoxon, Spearman’s rho, related and unrelated t-tests, and Pearson’s r). The notion of significance, probability levels, type I and type II errors must be understood. Reporting conventions follow the standard structure: abstract, introduction, method, results, discussion, references and appendices. Ethics demand informed consent, deception management, protection from harm, privacy, and right to withdraw, overseen by ethics committees.

研究方法是心理学探究的基石，涵盖实验设计、数据分析和伦理考量。目的和假设（定向与非定向）指导研究。独立组设计、重复测量设计和配对设计是常见实验设计，各有优势和局限。变量包括自变量、因变量和混淆变量（含需求特征和主试效应）。抽样技术从随机抽样、分层抽样到机会抽样和志愿者抽样。研究者使用实验（实验室、现场、自然、准实验）、观察（自然主义、控制、隐蔽、公开、参与式、非参与式）、自我报告技术（问卷、访谈）和相关分析。数据分析涉及描述统计（平均数、中位数、众数、全距、标准差）和推断统计（选择合适的检验，如符号检验、卡方检验、曼-惠特尼U检验、威尔科克森检验、斯皮尔曼相关系数、相关及不相关t检验、皮尔逊r）。必须掌握显著性的概念、概率水平、第一类与第二类错误。报告惯例遵循标准结构：摘要、引言、方法、结果、讨论、参考文献和附录。伦理要求知情同意、欺瞒处理、免受伤害、隐私权和退出权，由伦理委员会监督。

8. Issues and Debates | 议题与争论

Issues and debates in psychology address overarching themes that run through all topics, encouraging critical evaluation of theories and research. Gender bias includes alpha bias (exaggerating differences) and beta bias (minimising differences), and androcentrism leads to female behaviour being judged as abnormal. Cultural bias involves ethnocentrism and cultural relativism, with etic and emic approaches. Free will emphasises individual choice, while determinism encompasses hard, soft, biological, environmental, and psychic determinism. The nature-nurture debate examines the relative importance of heredity and environment; interactionism sees them as inseparable. Holism and reductionism debate whether it is better to analyse behaviour at a whole, integrated level or break it down into constituent parts (environmental, biological, and molecular reductionism). Idiographic and nomothetic approaches contrast the study of unique individuals with the search for general laws. Ethical implications of research studies and theories include social sensitivity and potential uses of psychological findings.

心理学的议题与争论涉及贯穿所有主题的宏观主题，鼓励对理论和研究进行批判性评估。性别偏见包括阿尔法偏向（夸大差异）和贝塔偏向（缩小差异），男性中心主义导致女性行为被判定为异常。文化偏见涉及种族中心主义和文化相对主义，以及非位和位方法。自由意志强调个体选择，而决定论涵盖硬决定论、软决定论、生物决定论、环境决定论和心理决定论。天性-教养辩论探讨遗传与环境的重要性；互动论认为二者不可分割。整体论与还原论争论是否应在整体层面分析行为，还是将其分解为构成部分（环境还原论、生物还原论和分子还原论）。特则研究与通则研究对比了对独特个体的研究和对普遍规律的寻求。研究及理论的伦理含义包括社会敏感性和心理学发现可能被如何使用的问题。

9. Option: Schizophrenia | 选项：精神分裂症

Schizophrenia is a severe mental disorder characterised by psychosis. Classification involves ICD-11 and DSM-5, using positive symptoms (hallucinations, delusions) and negative symptoms (avolition, speech poverty). Reliability and validity of diagnosis are concerns, including inter-rater reliability, comorbidity, and symptom overlap (e.g., with bipolar disorder). Biological explanations centre on the dopamine hypothesis (hyperdopaminergia in subcortical areas, hypodopaminergia in cortical areas) and neural correlates such as enlarged ventricles and reduced grey matter. Candidate genes are polygenic, and the diathesis-stress model integrates biological vulnerability with psychological triggers. Psychological explanations include family dysfunction (double bind theory, expressed emotion) and cognitive explanations (metarepresentation dysfunction and central control deficits leading to positive symptoms). Drug therapies include typical (chlorpromazine) and atypical (clozapine, risperidone) antipsychotics, which act as dopamine antagonists. Psychological therapies encompass CBTp, family therapy (reducing expressed emotion and improving communication), and token economies used in institutional settings. The interactionist approach, combining drug therapy and therapy, is considered the most effective management.

精神分裂症是一种以精神病性为特征的重性精神障碍。分类使用ICD-11和DSM-5，采用阳性症状（幻觉、妄想）和阴性症状（无欲、言语贫乏）。诊断的信度和效度是关注要点，包括评定者间信度、共病和症状重叠（如与双相障碍）。生物学解释集中于多巴胺假说（皮质下区域多巴胺能亢进，皮质区域多巴胺能低下）以及神经相关物，如脑室扩大和灰质减少。候选基因具有多基因特性，素质-应激模型将生物易感性与心理触发因素整合。心理学解释包括家庭功能障碍（双重束缚理论、情感表达）和认知解释（元表征功能障碍和中央控制缺陷导致阳性症状）。药物疗法包括典型抗精神病药（氯丙嗪）和非典型抗精神病药（氯氮平、利培酮），均为多巴胺拮抗剂。心理疗法包括CBTp、家庭治疗（降低情感表达并改善沟通）和机构环境中使用的代币制。互动主义取向将药物与治疗相结合，被视为最有效的管理方案。
