1. Research Methods: Experiments and Ethics | 研究方法：实验与伦理
In CIE Psychology, understanding how researchers gather evidence is essential. The experimental method involves manipulating an independent variable (IV) to observe its effect on a dependent variable (DV), while controlling extraneous variables. Laboratory experiments offer high internal validity but may lack ecological validity, whereas field experiments enhance realism but reduce control. Crucially, ethical guidelines protect participants from harm, ensure informed consent, and uphold confidentiality. For example, Milgram’s obedience study raised ethical debates about deception and emotional distress, which shaped today’s ethical review boards.
在 CIE 心理学中，理解研究者如何收集证据至关重要。实验法通过操纵自变量（IV）来观察其对因变量（DV）的影响，同时控制额外变量。实验室实验内部效度高，但可能缺乏生态效度；现场实验则增强了真实性，却降低了控制。至关重要的是，伦理准则保护参与者免受伤害，确保知情同意，并维护保密性。例如，Milgram 的服从实验引发了关于欺骗和情绪困扰的伦理争论，从而推动了当今伦理审查委员会的发展。
2. Biological Psychology: Brain, Hormones and Behaviour | 生物心理学：大脑、激素与行为
Biological psychology examines how neural and hormonal processes shape our actions. Key topics include the role of neurotransmitters such as serotonin in mood regulation and dopamine in reward pathways. The amygdala is vital for emotional memory, while the prefrontal cortex governs decision‑making. Hormones like adrenaline trigger fight‑or‑flight responses. One classic study, by Raine et al. (1997), used PET scans to show reduced prefrontal activity in impulsive murderers, suggesting a biological basis for aggression. Understanding these mechanisms helps us appreciate the biological underpinnings of psychological experiences.
生物心理学探讨神经和激素过程如何塑造行为。核心主题包括神经递质的作用，如血清素在情绪调节中的功能，以及多巴胺在奖励通路中的作用。杏仁核对情绪记忆至关重要，而前额叶皮层控制决策。肾上腺素等激素会引发战斗或逃跑反应。一项经典研究是 Raine 等人（1997）利用 PET 扫描发现冲动型杀人犯的前额叶活动降低，这提示攻击行为具有生物学基础。理解这些机制有助于我们认识心理体验的生物学根基。
3. Cognitive Psychology: Memory Models | 认知心理学：记忆模型
The study of memory is central to cognitive psychology. The multi‑ odel (Atkinson & Shiffrin, 1968) describes memory as consisting of sensory register, short‑term memory (STM) and long‑ memory (LTM). STM has a limited capacity of about 7 ± 2 items and a duration of around 18– ry Model (Baddeley & Hitch, 1974), which replaces the unitary STM with separate components: the central executive, phonological loop, visuospatial sketchpad and episodic buffer. These models help explain phenomena like the recency and primacy effects in free recall tasks.
记忆研究是认知心理学的核心。多存储模型（Atkinson 和 Shiffrin，1968）将记忆描述为由感官记忆、短期记忆（STM）和长期记忆（LTM）组成。STM 的容量有限，约为 7 ± 2 个项目，在不经复述的情况下保持约 18–30 秒。相比之下，LTM 的容量和持续时间几乎是无限的。另一个有影响力的理论是工作记忆模型（Baddeley 和 Hitch，1974），它将单一 STM 替换为独立的成分：中央执行系统、语音环路、视空间面板和情节缓冲器。这些模型有助于解释自由回忆任务中的近因效应和首因效应。
4. Cognitive Psychology: Perception and Visual Illusions | 认知心理学：知觉与视觉错觉
Perception is not a passive recording of sensory data but an active construction shaped by expectations and context. Gregory’s (1970) constructivist theory argues that we use past experience and inferences to interpret sensory information, which can lead to visual illusions when these inferences are mistaken. The Müller‑Lyer illusion, Ponzo illusion and the Ames room demonstrate how depth cues and size constancy mechanisms can mislead perception. Gibson’s (1966) direct theory, in contrast, suggests that the environment provides sufficient information (affordances) for perception without the need for interpretation. Understanding these theories helps us critically evaluate how we make sense of the world.
知觉并非被动地记录感觉数据，而是一种受预期和情境影响的主动建构。Gregory（1970）的建构主义理论认为，我们利用过往经验和推理来解释感觉信息，当这些推理出现错误时，就可能导致视觉错觉。Müller‑Lyer 错觉、Ponzo 错觉和 Ames 房间展示了深度线索和大小恒常性机制如何误导知觉。相反，Gibson（1966）的直接理论提出，环境提供了足够的信息（可得性），知觉无需解释过程。理解这些理论有助于我们批判性地评估自己如何理解世界。
5. Social Psychology: Conformity and Obedience | 社会心理学：从众与服从
Social influence explores how our thoughts and behaviours are shaped by others. Asch’s (1951) line‑judgement experiments revealed that even unambiguous situations can lead to conformity due to normative social influence – the desire to fit in. Factors affecting conformity include group size, unanimity and task difficulty. Obedience to authority was famously investigated by Milgram (1963), who found that 65% of participants administered what they believed to be dangerous electric shocks to a confederate when instructed by an authority figure. Variations in proximity, location and uniform strength influenced obedience rates. These studies highlight the power of situational factors over individual personality.
社会影响探讨我们的思想和行为如何受到他人塑造。Asch（1951）的线段判断实验揭示，即使在明确的情境下，规范性社会影响（渴望合群）也会导致从众。影响从众的因素包括群体规模、一致性和任务难度。对权威的服从在 Milgram（1963）的研究中得到了著名探讨：他发现 65% 的参与者在权威人物指示下，对一名假扮者施加了他们以为危险的强电击。接近度、地点和制服权威度的变化影响了服从率。这些研究突显了情境因素胜过个体人格的力量。
6. Developmental Psychology: Piaget’s Cognitive Stages | 发展心理学：皮亚杰的认知阶段
Jean Piaget’s theory of cognitive development describes how children’s thinking evolves through four stages. The sensorimotor stage (0–2 years) involves object permanence – understanding that objects exist even when out of sight. The pre‑operational stage (2–7 years) is marked by egocentrism and animism; children struggle with conservation tasks. During the concrete operational stage (7–11 years), logical reasoning about concrete events develops, but abstract thought is difficult. Finally, in the formal operational stage (11+ years), adolescents can handle abstract concepts and hypothetical thinking. Piaget’s ideas were informed by careful observations and clinical interviews, although critics point out he may have underestimated children’s abilities.
Jean Piaget 的认知发展理论描述了儿童思维如何经历四个阶段的发展。感知运动阶段（0–2 岁）涉及客体永久性——理解物体即使不在视线内依然存在。前运算阶段（2–7 岁）以自我中心和泛灵论为特征；儿童难以完成守恒任务。在具体运算阶段（7–11 岁），他们能够对具体事件进行逻辑推理，但抽象思维仍困难。最后，在形式运算阶段（11 岁及以上），青少年能处理抽象概念和假设性思考。Piaget 的观点基于细致的观察和临床访谈，尽管批评者指出他可能低估了儿童的能力。
7. Developmental Psychology: Attachment Theory | 发展心理学：依恋理论
Attachment is a deep emotional bond between an infant and caregiver, crucial for social and emotional development. Bowlby (1969) proposed that attachment is an innate evolutionary mechanism enhancing survival. He emphasized the importance of a warm, continuous relationship and introduced the concept of the internal working model – a mental representation of self and others that influences future relationships. Ainsworth’s (1978) ‘Strange Situation’ procedure identified three attachment styles: secure (type B), insecure‑avoidant (type A) and insecure‑resistant (type C). Secure attachment, associated with sensitive responsiveness, predicts better social outcomes. Cultural variations in attachment styles remind us that the ideal of security can be expressed differently across societies.
依恋是婴儿与照料者之间深厚的情感纽带，对社会和情感发展至关重要。Bowlby（1969）提出，依恋是一种先天的进化机制，有助于提高生存机会。他强调温暖、持续关系的重要性，并引入了内部工作模型的概念——一种关于自我和他人的心理表征，会影响未来的关系。Ainsworth（1978）的“陌生情境”程序识别出三种依恋风格：安全型（B 型）、不安全回避型（A 型）和不安全抗拒型（C 型）。安全型依恋与敏感回应相关，预示着更好的社会适应结果。依恋风格的文化差异提醒我们，安全感的理想模式在不同社会中可能以不同方式表达。
8. Individual Differences: Intelligence Theories | 个体差异：智力理论
Psychologists have debated whether intelligence is a single general ability or a collection of distinct faculties. Spearman (1904) proposed a general intelligence factor (g) based on positive correlations among different cognitive tests. In contrast, Gardner’s (1983) theory of multiple intelligences identifies eight independent types, including linguistic, logical‑mathematical, spatial, musical and interpersonal intelligence, suggesting that traditional IQ tests overlook many talents. Intelligence testing itself has a controversial history, with concerns about cultural bias and the misuse of scores. Modern approaches, such as Sternberg’s triarchic theory, balance analytical, creative and practical abilities, offering a broader view of what it means to be intelligent.
心理学家一直在争论智力是一种单一的一般能力还是多种独立能力的集合。Spearman（1904）根据不同认知测验之间的正相关提出了通用智力因素（g）。与之相对，Gardner（1983）的多元智能理论确定了八种独立的智能类型，包括语言、逻辑数学、空间、音乐和人际智能等，认为传统智商测验忽视了许多才能。智力测验本身具有争议的历史，人们担心存在文化偏见和分数滥用。现代方法如 Sternberg 的三元理论将分析、创造和实践能力结合起来，为“什么是聪明”提供了更广阔的视角。
9. Social Psychology: Bystander Effect and Prosocial Behaviour | 社会心理学：旁观者效应与亲社会行为
Why do people sometimes fail to help in emergencies? Latané and Darley (1970) proposed the decision model of bystander intervention, outlining five stages from noticing the event to taking action. At each stage, a bystander may be inhibited by factors such as diffusion of responsibility – the belief that someone else will help – and audience inhibition, the fear of embarrassment. The tragic murder of Kitty Genovese in 1964 galvanized research in this area, though later analysis showed media exaggeration of witness apathy. Piliavin et al. (1969) conducted field experiments on a New York subway and found that help was more likely when the victim appeared disabled rather than drunk, and when no one else assisted. Understanding these processes encourages proactive helping behaviour.
为什么人们在紧急情况下有时不去帮助？Latané 和 Darley（1970）提出了旁观者干预的决策模型，从注意到事件到采取行动分为五个阶段。在每个阶段，旁观者可能被责任扩散（相信别人会帮助）和观众抑制（害怕尴尬）等因素所阻碍。1964 年 Kitty Genovese 的悲惨谋杀案推动了这一领域的研究，尽管后来的分析显示媒体夸大了目击者的冷漠。Piliavin 等人（1969）在纽约地铁进行的现场实验发现，当受害者看起来残疾而非醉酒时，以及当没有其他人帮忙时，帮助更可能发生。理解这些过程有助于鼓励主动的亲社会行为。
10. Health Psychology: Stress, Coping and Well‑being | 健康心理学：压力、应对与幸福感
Stress is the body’s response to perceived demands or threats. The transactional model of stress (Lazarus & Folkman, 1984) focuses on the cognitive appraisal of stressors: primary appraisal assesses the threat, while secondary appraisal evaluates one’s coping resources. Chronic stress can lead to physical illness via immunosuppression, as demonstrated by Kiecolt‑Glaser et al. (1984) in a study linking exam stress to reduced immune function. Coping strategies are problem‑focused (addressing the stressor) or emotion‑focused (regulating emotional response). Social support acts as a buffer against stress. Techniques such as mindfulness and relaxation are evidence‑based ways to reduce stress levels and improve well‑being.
压力是身体对感知到的需求或威胁的反应。压力的交互作用模型（Lazarus 和 Folkman，1984）侧重于对压力源的认知评估：初级评估判断威胁程度，而次级评估评估个人的应对资源。慢性压力可通过免疫抑制导致身体疾病，Kiecolt‑Glaser 等人（1984）的研究将考试压力与免疫功能下降联系起来。应对策略分为以问题为中心（处理压力源本身）和以情绪为中心（调节情绪反应）。社会支持可作为压力的缓冲。正念和放松等技巧是证据支持的减轻压力水平、提升幸福感的有效方法。
