1. Memory: Encoding, Storage, and Retrieval | 记忆：编码、存储与提取

The Atkinson-Shiffrin three-stage model of memory proposes that information flows from sensory memory to short-term memory and then to long-term memory via encoding. Sensory memory holds fleeting sensory impressions, iconic (visual) and echoic (auditory), for a fraction of a second.

阿特金森-谢夫林的三阶段记忆模型提出，信息通过编码从感觉记忆进入短期记忆，再进入长时记忆。感觉记忆在几分之一秒内保存短暂的视觉（图像）和听觉（回声）印象。

Short-term memory (STM) has a limited capacity of about 7±2 items and lasts about 20-30 seconds without rehearsal. Working memory, a more dynamic model by Baddeley, includes the central executive, phonological loop, visuospatial sketchpad, and episodic buffer to actively process information.

短期记忆的容量有限，约为 7±2 个组块，若不进行复述只能保持 20-30 秒。巴德利提出的工作记忆模型更为动态，包含中央执行器、语音回路、视空间模板和情节缓冲区，以主动加工信息。

Encoding can be automatic or effortful. Levels of processing theory states that deeper, semantic encoding leads to better recall than shallow, structural or phonemic encoding. Mnemonics, chunking, and the spacing effect all enhance encoding.

编码可以是自动的或需要努力的。加工水平理论认为，深层次的语义编码比表层的结构或语音编码更能促进回忆。记忆术、组块化和间隔效应均能改善编码效果。

Long-term memory (LTM) stores information indefinitely. Explicit (declarative) memory includes episodic memory (personal events) and semantic memory (facts and knowledge). Implicit (nondeclarative) memory includes procedural memory (skills) and classical conditioning effects.

长时记忆无限期地存储信息。外显（陈述性）记忆包括情景记忆（个人事件）和语义记忆（事实和知识）。内隐（非陈述性）记忆则包括程序性记忆（技能）和经典条件作用的效果。

Memory Type	Description
Episodic Memory 情景记忆	Memory of personally experienced events, e.g. your first day at school. 对个人经历事件的记忆，例如第一天上学。
Semantic Memory 语义记忆	Factual knowledge, such as the capital of France. 事实性知识，如法国的首都。
Procedural Memory 程序性记忆	Motor skills and habits, e.g. riding a bicycle. 运动技能和习惯，例如骑自行车。

Retrieval involves getting information out of storage. Recall requires generating information from memory (e.g., essay questions), while recognition involves identifying previously learned items (e.g., multiple-choice tests). Context-dependent and state-dependent retrieval suggest that matching the learning environment or internal state aids memory.

提取是指将信息从存储中取出。回忆需要在记忆中生成信息（如简答题），再认则涉及识别先前学过的项目（如选择题）。情境依存和状态依存提取表明，匹配学习时的环境或内部状态有助于记忆。

2. Forgetting, Memory Construction, and Improving Memory | 遗忘、记忆重构与改善记忆

Ebbinghaus’s forgetting curve shows that most forgetting occurs soon after learning, then levels off. The two main explanations for forgetting are storage decay and retrieval failure. Interference theory differentiates proactive interference (old info disrupts new) and retroactive interference (new info disrupts old).

艾宾浩斯的遗忘曲线表明，大部分遗忘发生在学习后不久，之后遗忘速率减缓。遗忘的两个主要解释是存储衰退和提取失败。干扰理论区分了前摄干扰（旧信息干扰新信息）和倒摄干扰（新信息干扰旧信息）。

Memory is not a perfect recording; it is reconstructed each time we retrieve it. The misinformation effect (Loftus) shows that misleading post-event information can alter memories. Source amnesia occurs when we retain a memory but forget its origin, contributing to false memories.

记忆并非完美的录像，每次提取时都会被重构。误导信息效应（洛夫特斯）表明，事件后的误导信息可以改变记忆。来源遗忘症指我们保留了记忆却忘记其来源，这可能导致虚假记忆。

To improve memory, you can use distributed practice (spacing effect), overlearning, active recall, and mnemonic devices such as the method of loci or peg-word system. Making material personally meaningful also deepens encoding.

想要改善记忆，可以利用分散练习（间隔效应）、过度学习、主动回忆以及记忆术，如地点法或挂钩词系统。让材料具有个人意义也能加深编码。

3. Thinking, Problem Solving, and Decision Making | 思维、问题解决与决策

Thinking involves manipulating mental representations, often through concepts and prototypes. A concept is a mental grouping of similar objects, and a prototype is the best example of that concept. Problem solving can use algorithms (step-by-step guaranteed solution) or heuristics (mental shortcuts). Common heuristics include trial and error, means-end analysis, and working backward.

思维涉及对心理表征的操控，通常通过概念和原型来实现。概念是对相似对象的心理分组，原型则是该概念的最佳例证。问题解决可以使用算法（保证成功的逐步方案）或启发式（心理捷径）。常见的启发式包括尝试错误、手段—目的分析和逆向操作。

Obstacles to problem solving include confirmation bias (searching for evidence that supports our beliefs), fixation (inability to see a problem from a new perspective), and functional fixedness (failing to see novel uses for objects). Mental set is the tendency to approach problems using previously successful strategies.

问题解决的障碍包括确认偏误（寻找支持自身信念的证据）、固着（无法从新角度看待问题）以及功能固着（未能看到物品的新用途）。心理定势是指倾向于用过去成功的策略来解决问题的倾向。

In decision making, the representativeness heuristic judges the likelihood of something based on how well it matches a prototype, while the availability heuristic estimates likelihood based on how easily examples come to mind. Framing effects demonstrate that the way an issue is presented can drastically alter decisions.

在决策中，代表性启发式根据事物与原型匹配的程度来判断可能性，可得性启发式则依据例证在脑海中的轻易程度来估计概率。框架效应表明，问题的呈现方式能极大地改变决策。

4. Language and Intelligence | 语言与智力

Language consists of phonemes (smallest sound units), morphemes (smallest meaning units), and grammar (syntax and semantics). Chomsky proposed that humans have a universal grammar and a language acquisition device (LAD) that enables rapid language learning during the critical period.

语言由音素（最小的声音单位）、词素（最小的意义单位）和语法（句法与语义）构成。乔姆斯基提出人类拥有普遍语法和语言习得装置，这使得在关键期内能够快速学会语言。

Intelligence is the ability to learn from experience, solve problems, and use knowledge to adapt. Spearman’s g factor theory suggests a general intelligence underlies all mental abilities. Gardner proposed multiple intelligences (e.g., linguistic, logical-mathematical, musical, spatial). Sternberg’s triarchic theory includes analytical, creative, and practical intelligence.

智力是从经验中学习、解决问题以及运用知识适应环境的能力。斯皮尔曼的g因素理论认为存在一种通用智力支撑所有心理能力。加德纳提出多元智力（如语言、逻辑-数学、音乐、空间智力）。斯滕伯格的三元理论包含分析性、创造性和实践性智力。

Intelligence tests such as the Stanford-Binet and Wechsler scales (WAIS, WISC) provide IQ scores. Standardisation, reliability, and validity are essential for good tests. The Flynn effect refers to the observed rise in IQ scores over generations. Cultural bias in testing remains a concern.

斯坦福-比奈量表和韦氏智力量表（WAIS, WISC）提供智商分数。标准化、信度和效度是良好测试的必备条件。弗林效应指观察到的代际智商分数上升。测试中的文化偏见仍是一个值得关注的问题。

5. Developmental Psychology: Prenatal to Childhood | 发展心理学：产前至童年

Prenatal development progresses through the germinal, embryonic, and fetal stages. Teratogens, such as alcohol and drugs, can harm the developing embryo or fetus. Fetal alcohol syndrome (FAS) leads to cognitive and physical abnormalities.

产前发育依次经历胚种期、胚胎期和胎儿期。致畸原，如酒精和药物，可损害发育中的胚胎或胎儿。胎儿酒精综合征会导致认知和身体异常。

Newborns possess reflexes like rooting, sucking, and grasping. Piaget’s theory of cognitive development describes four stages: sensorimotor (0-2, object permanence), preoperational (2-7, egocentrism, lack of conservation), concrete operational (7-11, logical thinking about concrete events), and formal operational (12+, abstract reasoning).

新生儿具备觅食反射、吸吮反射和抓握反射等。皮亚杰的认知发展理论描述了四个阶段：感知运动阶段（0-2岁，客体永存性）、前运算阶段（2-7岁，自我中心，缺乏守恒）、具体运算阶段（7-11岁，对具体事件的逻辑思维）和形式运算阶段（12岁以上，抽象推理）。

Attachment is an emotional bond with a caregiver. Harlow’s monkey studies proved the importance of contact comfort. Ainsworth’s strange situation identified secure attachment, insecure-avoidant, and insecure-ambivalent (anxious) attachment styles. Parenting styles (Baumrind) include authoritative, authoritarian, permissive, and neglectful, with authoritative style linked to the most positive outcomes.

依恋是与照顾者之间的情感纽带。哈洛的恒河猴实验证明了接触安慰的重要性。安斯沃斯的陌生情境实验区分了安全型、不安全回避型和不安全矛盾型（焦虑型）依恋。鲍姆林德的教养风格包括权威型、专制型、放纵型和忽视型，其中权威型与最积极的发展结果相关。

6. Developmental Psychology: Adolescence to Adulthood | 发展心理学：青春期至成年

Adolescence begins with puberty, marked by primary and secondary sex characteristics. The frontal lobe continues developing, which may explain increased risk-taking. Kohlberg’s stages of moral development progress from preconventional (obedience, self-interest), to conventional (social approval, law and order), to postconventional (social contract, universal ethics).

青春期始于青春期，标志着第一和第二性征出现。额叶仍在发育，这或许能解释为何冒险行为增加。科尔伯格的道德发展三水平六阶段从习俗前水平（服从、自利），到习俗水平（社会认可、法律秩序），再到后习俗水平（社会契约、普遍伦理）。

Erikson’s psychosocial stages span the entire lifespan. Key stages include identity vs. role confusion (adolescence), intimacy vs. isolation (young adulthood), generativity vs. stagnation (middle adulthood), and integrity vs. despair (late adulthood). Successful resolution of each stage leads to a healthy personality.

埃里克森的心理社会发展阶段贯穿整个生命周期。关键阶段包括：自我同一性对角色混乱（青春期），亲密对孤独（成年早期），繁衍对停滞（成年中期），以及完善对绝望（成年晚期）。成功解决每个阶段的冲突会带来健康的人格。

Cognitive changes in adulthood include a possible decline in fluid intelligence (speed and abstract reasoning) while crystallised intelligence (accumulated knowledge) remains stable or increases. Ageing involves adjustments, but many older adults maintain high life satisfaction and cognitive engagement through active lifestyles.

成年期的认知变化包括液态智力（速度和抽象推理）可能下降，而晶态智力（累积知识）则保持稳定或提高。衰老需要适应，但许多老年人通过积极的生活方式保持较高的生活满意度和认知参与。

7. Motivation and Emotion | 动机与情绪

Motivation theories seek to explain why we initiate and persist in behaviours. Drive-reduction theory posits that physiological needs create an aroused state (drive) that pushes us to reduce the need and restore homeostasis. Arousal theory suggests we seek an optimal level of stimulation, as shown by the Yerkes-Dodson law.

动机理论旨在解释我们为何发起并维持行为。驱力减少理论认为，生理需求会产生唤醒状态（驱力），驱使我们减少需求并恢复体内平衡。唤醒理论则主张我们寻求最佳刺激水平，耶克斯-多德森定律说明了这一点。

Maslow’s hierarchy of needs ranks human needs from basic physiological needs, safety, love/belonging, and esteem, up to self-actualisation and self-transcendence. Self-determination theory emphasises autonomy, competence, and relatedness as key psychological needs.

马斯洛的需求层次理论将人类需求由低到高排列为生理需求、安全需求、爱与归属、尊重，直至自我实现和自我超越。自我决定理论强调自主性、胜任力和归属感是核心的心理需求。

Emotion involves expressive behaviours, physiological arousal, and conscious experience. The James-Lange theory states that arousal comes before emotion (we feel sad because we cry). The Cannon-Bard theory argues arousal and emotion occur simultaneously. Schachter-Singer’s two-factor theory adds cognitive appraisal: emotion depends on physiological arousal plus a cognitive label.

情绪涉及表达行为、生理唤醒和意识体验。詹姆斯-兰格理论认为生理唤醒先于情绪（我们因为哭泣才感到悲伤）。坎农-巴德理论主张唤醒与情绪同时发生。沙赫特-辛格的双因素理论则加入了认知评价：情绪取决于生理唤醒加上认知标签。

Stress is the process by which we perceive and respond to threats. General adaptation syndrome (Selye) includes alarm, resistance, and exhaustion phases. Coping can be problem-focused or emotion-focused. Perceived control and social support buffer the effects of stress.

压力是我们对威胁的感知与反应过程。塞利的一般适应综合征包含警觉期、抵抗期和衰竭期。应对方式可分为问题聚焦和情绪聚焦两种。感知到的控制感和社会支持能缓冲压力的影响。

8. Theories of Personality | 人格理论

Psychoanalytic theory (Freud) divides mind into id, ego, and superego and proposes psychosexual stages: oral, anal, phallic, latency, and genital. Defence mechanisms like repression, denial, and projection protect the ego from anxiety. Neo-Freudians such as Jung (collective unconscious), Adler (inferiority complex), and Horney (basic anxiety) shifted focus to social and cultural factors.

精神分析理论（弗洛伊德）将心理划分为本我、自我和超我，并提出性心理发展阶段：口唇期、肛门期、性器期、潜伏期和生殖期。压抑、否认、投射等防御机制保护自我免受焦虑。新弗洛伊德主义者如荣格（集体无意识）、阿德勒（自卑情结）和霍妮（基本焦虑）将焦点转向社会文化因素。

Humanistic theories focus on personal growth. Rogers emphasised unconditional positive regard and the self-concept, saying incongruence between ideal self and actual self causes distress. Maslow studied self-actualised individuals. Trait theories describe personality in terms of stable characteristics. The Big Five (OCEAN) traits are openness, conscientiousness, extraversion, agreeableness, and neuroticism.

人本主义理论关注个人成长。罗杰斯强调无条件积极关注和自我概念，认为理想自我与现实自我之间的不一致会导致困扰。马斯洛则研究自我实现者。特质理论用稳定的特征描述人格。大五人格（OCEAN）特质包括开放性、尽责性、外向性、宜人性和神经质。

Social-cognitive theory (Bandura) highlights reciprocal determinism: behaviour, personal factors, and environment interact. Rotter’s locus of control distinguishes between internal and external orientations. A person with an internal locus of control believes they control their own fate.

社会认知理论（班杜拉）强调交互决定论：行为、个人因素和环境相互影响。罗特的控制点理论区分了内控和外控倾向。内控型的人相信命运由自己掌控。

9. Introduction to Psychological Disorders | 心理障碍导论

Psychological disorders are patterns of thoughts, feelings, or behaviours that are deviant, distressful, dysfunctional, and sometimes dangerous. The DSM-5 is the standard classification system, using diagnostic labels and criteria. The medical model views disorders as illnesses to be diagnosed and treated.

心理障碍是指思维、情感或行为模式偏离常态、令人痛苦、功能失调且有时具有危险性的状况。DSM-5 是标准的分类系统，使用诊断标签和标准。医学模型将障碍视作可以诊断和治疗的疾病。

Anxiety disorders include generalised anxiety disorder (GAD), panic disorder, phobias, and social anxiety disorder. They involve intense, persistent anxiety or fear. Depressive disorders, such as major depressive disorder and persistent depressive disorder, feature prolonged sadness and loss of interest. Bipolar disorder involves alternating depression and mania.

焦虑障碍包括广泛性焦虑障碍、惊恐障碍、恐怖症和社交焦虑障碍，表现为强烈而持久的焦虑或恐惧。抑郁障碍，如重度抑郁障碍和持续性抑郁障碍，以持续的悲伤和兴趣丧失为特征。双相障碍涉及抑郁和躁狂交替发作。

Schizophrenia is characterised by hallucinations, delusions, disorganised thinking, and inappropriate affect. Positive symptoms add behaviours (e.g., hallucinations), while negative symptoms take them away (e.g., flat affect). Personality disorders, like antisocial and borderline personality disorders, involve enduring maladaptive patterns of behaviour.

精神分裂症以幻觉、妄想、思维紊乱和情感不协调为特征。阳性症状增加行为（如幻觉），阴性症状则减少行为（如情感淡漠）。人格障碍，如反社会型人格障碍和边缘型人格障碍，表现为持久适应不良的行为模式。

The biopsychosocial model integrates biological (genetics, brain chemistry), psychological (coping, trauma), and social–cultural (poverty, expectations) factors to explain the onset of disorders.

生物心理社会模型综合了生物学（基因、脑化学）、心理学（应对方式、创伤）和社会文化（贫困、期望）等因素来解释障碍的发生。

10. Treatment of Psychological Disorders | 心理障碍的治疗

Psychodynamic therapy explores unconscious conflicts and past experiences, using free association and dream analysis. Humanistic therapy, exemplified by Rogers’ client-centred therapy, emphasises empathy, genuineness, and unconditional positive regard to promote self-growth. Behaviour therapies apply learning principles: systematic desensitisation pairs relaxation with anxiety-provoking stimuli, exposure therapy confronts fears directly, and token economies reinforce desired behaviours.
