1. Research Methods and Statistics | 研究方法与统计

The experiment is the only research method that can determine cause and effect. It involves random assignment of participants to experimental and control groups, manipulation of the independent variable (IV), and measurement of the dependent variable (DV).

实验是唯一能确定因果关系的研究方法。它涉及将被试随机分配到实验组和控制组，操纵自变量(IV)，并测量因变量(DV)。

Confounding variables, such as the placebo effect and experimenter bias, are controlled through double-blind procedures and random assignment.

混淆变量，如安慰剂效应和实验者偏差，通过双盲程序和随机分配来控制。

A correlation coefficient (r) describes the strength and direction of a relationship between two variables, ranging from -1.00 to +1.00. Remember that correlation does not imply causation.

相关系数(r)描述两个变量之间关系的强度和方向，范围从-1.00到+1.00。记住，相关不意味着因果关系。

Descriptive statistics include measures of central tendency (mean, median, mode) and measures of variability (range, standard deviation). Inferential statistics determine whether results are statistically significant, typically using a p-value of less than 0.05.

描述性统计包括集中趋势的度量（平均数、中位数、众数）和离差的度量（全距、标准差）。推论统计用于判断结果是否具有统计显著性，通常采用p值小于0.05的标准。

Ethical guidelines from the APA require informed consent, protection from harm, confidentiality, and debriefing after the study.

美国心理学会(APA)的伦理准则要求在实验前获得知情同意、保护被试免受伤害、保密以及在实验后进行事后解释。

2. Biological Bases of Behavior | 行为的生物学基础

Neurons communicate through an electrochemical process. An action potential travels down the axon, triggering the release of neurotransmitters into the synapse. These chemicals bind to receptor sites on the receiving neuron.

神经元通过电化学过程进行交流。动作电位沿轴突传导，触发神经递质释放到突触间隙。这些化学物质与接收神经元上的受体位点结合。

Key neurotransmitters and their functions are frequently tested. Acetylcholine (ACh) is involved in muscle contraction and memory. Dopamine is linked to reward, movement, and attention; imbalances are associated with schizophrenia and Parkinson’s disease. Serotonin affects mood, appetite, and sleep. Norepinephrine is related to alertness and arousal. GABA reduces neural activity, while glutamate increases it.

重要神经递质及其功能是常考内容。乙酰胆碱(ACh)参与肌肉收缩和记忆。多巴胺与奖赏、运动和注意有关；其失衡与精神分裂症和帕金森病相关。血清素影响情绪、食欲和睡眠。去甲肾上腺素与警觉和唤醒有关。GABA抑制神经活动，而谷氨酸则增强神经活动。

The central nervous system consists of the brain and spinal cord. Major brain regions include the brainstem (medulla, pons, reticular formation), cerebellum, limbic system (amygdala, hippocampus, hypothalamus), and cerebral cortex (four lobes). The frontal lobe is responsible for executive functions, motor cortex, and Broca’s area.

中枢神经系统由脑和脊髓组成。主要脑区包括脑干（延髓、脑桥、网状结构）、小脑、边缘系统（杏仁核、海马、下丘脑）和大脑皮层（四个叶）。额叶负责执行功能、运动皮层和布洛卡区。

Brain Structure	Function	脑结构	功能
Amygdala	Emotion, fear processing	杏仁核	情绪、恐惧加工
Hippocampus	Memory formation	海马	记忆形成
Hypothalamus	Homeostasis, reward, endocrine control	下丘脑	内稳态、奖赏、内分泌控制

Split-brain research by Sperry and Gazzaniga revealed that the left hemisphere is dominant for language and logic, while the right hemisphere excels in spatial and facial recognition.

Sperry和Gazzaniga的裂脑研究揭示，左半球在语言和逻辑方面占优势，而右半球在空间和面孔识别方面更擅长。

3. Sensation and Perception | 感觉与知觉

Sensation is the process of detecting physical stimuli from the environment, while perception involves interpreting and organizing sensory information. Absolute threshold is the minimum stimulus needed to detect a stimulus 50% of the time; difference threshold (just noticeable difference) follows Weber’s law.

感觉是探测环境中物理刺激的过程，而知觉则涉及解释和组织感觉信息。绝对阈限是在50%的测试次数中能察觉到刺激所需的最低刺激强度；差别阈限（最小可觉差）遵循韦伯定律。

In vision, light enters through the cornea and pupil, is focused by the lens, and projected onto the retina. Rods detect brightness and motion; cones detect color and fine detail, concentrated in the fovea. Color vision is explained by trichromatic theory (three types of cones) and opponent-process theory (red-green, blue-yellow, black-white pairs).

视觉中，光线通过角膜和瞳孔进入，由晶状体聚焦，投射到视网膜上。视杆细胞探测亮度和运动；视锥细胞探测颜色和细节，集中在中央凹。色觉由三色理论（三种视锥细胞）和拮抗加工理论（红-绿、蓝-黄、黑-白对）解释。

Gestalt principles describe how we organize visual input: figure-ground, proximity, similarity, continuity, and closure. Depth perception relies on binocular cues (retinal disparity, convergence) and monocular cues (relative size, linear perspective, texture gradient).

格式塔原则描述我们如何组织视觉信息：图形-背景、接近性、相似性、连续性、闭合性。深度知觉依赖于双眼线索（视网膜视差、辐合）和单眼线索（相对大小、线条透视、纹理梯度）。

4. Learning | 学习

Classical conditioning, discovered by Pavlov, involves pairing a neutral stimulus (NS) with an unconditioned stimulus (UCS) that naturally elicits an unconditioned response (UCR). After repeated pairings, the NS becomes a conditioned stimulus (CS) that triggers a conditioned response (CR). Key processes include acquisition, extinction, spontaneous recovery, generalization, and discrimination.

巴甫洛夫发现的经典条件作用涉及将中性刺激(NS)与能自然引起非条件反应(UCR)的非条件刺激(UCS)配对。多次配对后，中性刺激变成条件刺激(CS)，引发条件反应(CR)。关键过程包括习得、消退、自然恢复、泛化和分化。

Operant conditioning, studied by Skinner, uses rewards and punishments to shape behavior. Positive reinforcement adds a desirable stimulus to increase behavior; negative reinforcement removes an aversive stimulus. Schedules of reinforcement (fixed/variable ratio and interval) influence response patterns and resistance to extinction.

斯金纳研究的操作性条件作用利用奖赏和惩罚来塑造行为。正强化通过增加愉悦刺激来提高行为频率；负强化通过移除厌恶刺激来提高行为频率。强化程式（固定/变化比率与间隔）影响反应模式和对消退的抗拒。

Bandura’s social learning theory emphasizes observational learning and modeling. Children imitated aggressive behavior in the famous Bobo doll experiment, highlighting the role of cognitive processes and vicarious reinforcement.

班杜拉的社会学习理论强调观察学习和模仿。在著名的波波玩偶实验中，儿童模仿攻击行为，突显了认知过程和替代性强化的作用。

5. Cognitive Psychology | 认知心理学

The information-processing model of memory includes sensory memory (iconic and echoic), short-term/working memory (limited capacity, about 7±2 items), and long-term memory (explicit/declarative and implicit/nondeclarative). Long-term potentiation is the neural basis for memory formation.

记忆的信息加工模型包括感觉记忆（图像记忆和声像记忆）、短时/工作记忆（容量有限，约7±2个组块）和长时记忆（外显/陈述性记忆和内隐/非陈述性记忆）。长时程增强是记忆形成的神经基础。

Ebbinghaus discovered the forgetting curve and the benefits of distributed practice. Serial position effect shows better recall for items at the beginning (primacy) and end (recency) of a list. Interference theory (proactive and retroactive) explains forgetting from long-term memory.

艾宾浩斯发现了遗忘曲线和分散练习的益处。系列位置效应显示，对列表开头（首因效应）和结尾（近因效应）项目的回忆效果更好。干扰理论（前摄干扰和倒摄干扰）解释了长时记忆的遗忘。

Cognition also covers problem solving, decision making, and language. Heuristics (mental shortcuts) like availability and representativeness can lead to errors. Chomsky proposed an innate language acquisition device (LAD), and Whorf’s linguistic relativity hypothesis suggests language influences thought.

认知还涵盖问题解决、决策和语言。启发式（心理捷径）如可得性启发和代表性启发可能导致错误。乔姆斯基提出了先天的语言习得装置(LAD)，而沃尔夫的语言相对论假说认为语言影响思维。

皮亚杰的认知发展阶段包括感知运动阶段（客体永久性）、前运算阶段（自我中心、缺乏守恒）、具体运算阶段（对具体事件的逻辑思维）和形式运算阶段（抽象推理）。

Vygotsky emphasized the zone of proximal development and scaffolding, highlighting the role of social interaction and language in cognitive growth.

维果茨基强调最近发展区和支架作用，突出了社会互动和语言在认知发展中的作用。

Erikson’s psychosocial theory outlines eight stages, each with a specific conflict. Adolescence focuses on identity vs. role confusion, while young adulthood centers on intimacy vs. isolation.

埃里克森的心理社会发展理论划分了八个阶段，每个阶段都有特定的冲突。青少年期聚焦于自我同一性对角色混乱，而成年早期聚焦于亲密对孤独。

Attachment styles (secure, anxious-ambivalent, avoidant) studied by Ainsworth through the Strange Situation predict later social and emotional outcomes. Harlow’s monkey studies demonstrated the importance of contact comfort over feeding.

安斯沃斯通过陌生情境实验研究的依恋类型（安全型、焦虑-矛盾型、回避型）可以预测日后的社会和情感发展。哈洛的猴子实验证明了接触舒适比喂食更重要。

7. Motivation, Emotion, and Stress | 动机、情绪与压力

Drive-reduction theory explains motivation as the desire to reduce internal tension caused by unmet biological needs (homeostasis). Arousal theory suggests people seek an optimal level of arousal. Maslow’s hierarchy of needs ranges from physiological needs to self-actualization.

驱力降低理论将动机解释为减少由未满足的生物需求引起的内在紧张的愿望（内稳态）。唤醒理论认为人们追求最佳唤醒水平。马斯洛的需求层次从生理需求到自我实现。

Intrinsic motivation comes from within (enjoyment), while extrinsic motivation comes from external rewards. Overjustification effect occurs when external rewards undermine intrinsic motivation.

内部动机来源于内在（兴趣），而外部动机来自外部奖励。过度合理化效应指外部奖励削弱了内部动机。

Major theories of emotion include the James-Lange theory (physiological arousal comes first, then emotion), Cannon-Bard theory (arousal and emotion occur simultaneously), Schachter-Singer two-factor theory (arousal + cognitive label), and Lazarus’s cognitive-mediational theory (appraisal precedes emotion).

主要的情绪理论包括詹姆斯-兰格理论（生理唤醒先行，然后情绪）、坎农-巴德理论（唤醒和情绪同时发生）、沙赫特-辛格双因素理论（唤醒+认知标签）和拉扎勒斯的认知中介理论（评价先于情绪）。

Stress responses involve the alarm, resistance, and exhaustion stages of General Adaptation Syndrome (Selye). Coping strategies can be problem-focused or emotion-focused.

压力反应涉及塞利提出的一般适应综合征的警觉、抵抗和衰竭阶段。应对策略可以是问题焦点应对或情绪焦点应对。

8. Personality | 人格

Freud’s psychoanalytic theory divides the mind into id (pleasure principle), ego (reality principle), and superego (morality). Defense mechanisms like repression, projection, and displacement reduce anxiety. Psychosexual stages (oral, anal, phallic, latency, genital) shape personality.

弗洛伊德的精神分析理论将心灵分为本我（快乐原则）、自我（现实原则）和超我（道德原则）。防御机制如压抑、投射和转移可以减少焦虑。性心理发展阶段（口唇期、肛门期、性器期、潜伏期、生殖期）塑造人格。

Trait theories, like the Big Five (OCEAN: openness, conscientiousness, extraversion, agreeableness, neuroticism), provide a stable, descriptive model of personality. Eysenck emphasized extraversion and neuroticism.

特质理论，如大五人格（OCEAN：开放性、尽责性、外向性、宜人性、神经质），提供了一个稳定且描述性的人格模型。艾森克强调外向性和神经质。

Humanistic theories by Rogers and Maslow focus on self-concept, unconditional positive regard, and the drive toward self-actualization.

罗杰斯和马斯洛的人本主义理论关注自我概念、无条件积极关注和朝向自我实现的驱力。

Projective tests (Rorschach, TAT) and self-report inventories (MMPI, Big Five scales) are used to assess personality.

投射测验（罗夏墨迹测验、主题统觉测验）和自我报告量表（MMPI、大五量表）用于评估人格。

9. Clinical Psychology | 临床心理学

The DSM-5 is used to classify psychological disorders. Anxiety disorders include generalized anxiety disorder (GAD), panic disorder, phobias, and OCD. Major depressive disorder involves persistent low mood and loss of interest. Bipolar disorder features alternating mania and depression. Schizophrenia involves delusions, hallucinations, disorganized speech, and negative symptoms.

DSM-5用于分类心理障碍。焦虑障碍包括广泛性焦虑障碍(GAD)、惊恐障碍、恐怖症和强迫症(OCD)。重性抑郁障碍涉及持续的情绪低落和兴趣丧失。双相障碍的特点是躁狂和抑郁交替发作。精神分裂症涉及妄想、幻觉、言语紊乱和阴性症状。

Etiology of disorders is explained using the biopsychosocial model, integrating biological (genetics, neurotransmitters), psychological (stress, cognition), and social (family, culture) factors.

障碍的病因学通过生物-心理-社会模型来解释，整合了生物（遗传、神经递质）、心理（压力、认知）和社会（家庭、文化）因素。

Therapies can be categorized into biomedical (psychopharmacology, ECT) and psychotherapy. Key psychotherapies include psychoanalytic (free association, transference), humanistic (client-centered therapy, active listening), cognitive-behavioral (CBT, challenging irrational beliefs), and behavioral (systematic desensitization, token economy).

治疗方法可分为生物医学治疗（精神药理学、电休克疗法）和心理治疗。主要心理治疗包括精神分析（自由联想、移情）、人本主义（来访者中心疗法、积极倾听）、认知行为（CBT、挑战非理性信念）和行为治疗（系统脱敏、代币制）。

Effectiveness of therapy is often enhanced by a therapeutic alliance and by evidence-based practice.

治疗的有效性通常因治疗联盟和循证实践而增强。

10. Social Psychology | 社会心理学

Conformity, investigated by Asch, shows people may agree with the group even when the group is wrong. Obedience, studied by Milgram, demonstrated that ordinary people can follow orders to harm others under authority pressure.

阿希研究的从众现象表明，即使群体是错的，人们也可能与群体保持一致。米尔格拉姆研究的服从现象表明，在权威压力下，普通人可能会服从伤害他人的命令。

Compliance techniques include foot-in-the-door (small request followed by larger), door-in-the-face (large request followed by smaller), and low-ball. Cognitive dissonance theory (Festinger) explains how we change attitudes to reduce discomfort from inconsistent beliefs and behaviors.

顺从技巧包括登门槛效应（先小要求后大要求）、留面子效应（先大要求后小要求）和低球手法。认知失调理论（费斯廷格）解释了人们如何改变态度以减少因信念与行为不一致而产生的不适。

Attribution theory distinguishes between internal (dispositional) and external (situational) attributions. The fundamental attribution error is overestimating personal factors when judging others’ behavior, while actor-observer bias involves attributing our own actions to situations.

归因理论区分内部（特质）归因和外部（情境）归因。基本归因错误是在判断他人行为时高估个人因素，而行动者-观察者偏差涉及将我们自己的行为归因于情境。

Group dynamics include social facilitation, social loafing, deindividuation, group polarization, and groupthink. Bystander effect and diffusion of responsibility explain why people are less likely to help in a group.

群体动力学包括社会助长、社会惰化、去个体化、群体极化和群体思维。旁观者效应和责任扩散解释了为什么人们在群体中更不可能提供帮助。

Prejudice is reduced by contact between groups under cooperative, equal-status conditions (contact hypothesis).

通过合作性和地位平等条件下的群体接触，偏见可以减少（接触假说）。
