1. Research Methods and Experimental Design | 研究方法与实验设计
Psychologists use experiments to establish cause-and-effect relationships. An independent variable (IV) is manipulated, and its effect on a dependent variable (DV) is measured while controlling extraneous variables. Laboratory experiments offer high internal validity but may lack ecological validity; field experiments occur in natural settings but introduce more uncontrolled variables.
心理学家通过实验确立因果关系。操纵自变量 (IV)，测量其对因变量 (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；现场实验在自然环境中进行，但会引入更多不可控变量。
Three experimental designs are common: independent groups (different participants in each condition), repeated measures (same participants in all conditions) and matched pairs (participants are paired on relevant traits). Counterbalancing is used in repeated measures to reduce order effects.
常见的实验设计有三种：独立组设计（不同参与者参与不同条件）、重复测量设计（相同参与者参与所有条件）和配对组设计（按相关特质配对参与者）。在重复测量设计中运用平衡对抗法来降低顺序效应。
Ethical guidelines from the British Psychological Society (BPS) require informed consent, protection from harm, right to withdraw and debriefing. Studies such as Milgram’s (1963) obedience experiment raised significant ethical concerns about deception and psychological stress.
英国心理学会 (BPS) 的伦理准则要求知情同意、保护免受伤害、有权退出和事后追询。像 Milgram (1963) 的服从实验这类研究引发了关于欺骗和心理压力的重大伦理关切。
2. Biological Psychology: Brain and Neurotransmission | 生物心理学：大脑与神经传递
Biological psychology examines how neural processes influence behaviour. Neurotransmitters such as serotonin, dopamine and acetylcholine transmit signals across synapses. For instance, low serotonin has been linked to aggression and depression, while dopamine is associated with reward and addiction.
生物心理学考察神经过程如何影响行为。神经递质如血清素、多巴胺和乙酰胆碱在突触间传递信号。例如，血清素水平低下与攻击性和抑郁有关，而多巴胺与奖赏和成瘾相关。
Split-brain research by Sperry (1968) demonstrated hemispheric lateralisation. Participants who had their corpus callosum severed could not verbally name objects presented to the left visual field but could select them with their left hand. This provided strong evidence that the right hemisphere processes information in a non-verbal manner.
Sperry (1968) 的裂脑研究证明了大脑功能偏侧化。切断胼胝体的参与者无法口头说出呈现给左视野的物体，但能用左手选出。这强有力地证明了右半球以非语言方式处理信息。
Raine et al. (1997) used PET scans to compare the brains of murderers pleading not guilty by reason of insanity with matched controls. They found reduced activity in prefrontal cortex and limbic system areas, indicating a link between brain dysfunction and violent behaviour. However, correlation does not equal causation.
Raine 等人 (1997) 运用 PET 扫描比较了因精神异常而作无罪辩护的谋杀犯与匹配对照组的大脑。他们发现前额叶皮层和边缘系统活动减少，表明脑功能异常与暴力行为之间的联系。然而，相关性不等于因果性。
3. Biological Psychology: Sleep and Dreams | 生物心理学：睡眠与梦
Sleep follows an ultradian rhythm with cycles of approximately 90 minutes, consisting of NREM (stages 1-3) and REM (rapid eye movement) sleep. REM sleep is strongly associated with dreaming, restored energy and brain maturation. The activation-synthesis theory (Hobson & McCarley, 1977) proposes that dreams are the brain’s attempt to make sense of random neural signals from the brainstem.
睡眠遵循超日节律，周期约为 90 分钟，由 NREM（非快速眼动，第 1-3 阶段）和 REM（快速眼动）睡眠组成。REM 睡眠与做梦、恢复能量和大脑成熟密切相关。激活-合成理论 (Hobson & McCarley, 1977) 提出，梦是大脑试图理解来自脑干的随机神经信号的结果。
Dement and Kleitman (1957) monitored participants’ EEG, EOG and EMG during sleep in a laboratory. They found a positive correlation between reported dream recall and time spent in REM sleep, and that the direction of eye movements during REM matched dream imagery. This study established REM as an objective indicator of dreaming.
Dement 和 Kleitman (1957) 在实验室中监测参与者的脑电图、眼电图和肌电图。他们发现报告的梦境回忆与 REM 睡眠时长呈正相关，并且 REM 期间的眼动方向与梦境影像吻合。该研究确立了 REM 作为做梦的客观指标。
Disrupted sleep can impair cognitive functioning and mental health. However, the restorative theory is reductionist, as it focuses only on biological mechanisms and ignores individual differences in sleep requirements and the influence of cultural practices.
睡眠中断会损害认知功能和心理健康。然而，恢复理论具有还原论色彩，因为它仅聚焦生物学机制，忽略了睡眠需求的个体差异以及文化习惯的影响。
4. Cognitive Psychology: Models of Memory | 认知心理学：记忆模型
The multi-store model (Atkinson & Shiffrin, 1968) distinguishes between sensory register, short-term memory (STM) and long-term memory (LTM). Information moves from STM to LTM via rehearsal. STM has limited capacity (7±2 items) and duration (around 18-30 seconds), whereas LTM is potentially unlimited.
多储存库模型 (Atkinson & Shiffrin, 1968) 区分了感觉登记、短时记忆 (STM) 和长时记忆 (LTM)。信息通过复述从 STM 转移到 LTM。STM 容量有限（7±2 组块）且持续时间短（约 18-30 秒），而 LTM 潜能无限。
Baddeley and Hitch’s (1974) working memory model replaced the unitary STM with four components: central executive, phonological loop, visuo-spatial sketchpad and episodic buffer. The phonological loop explains the word-length effect and articulatory suppression. This model better accounts for dual-task performance and active processing.
Baddeley 和 Hitch (1974) 的工作记忆模型用四个成分取代了单一 STM：中央执行系统、语音环、视觉空间模板和情景缓冲器。语音环解释了词长效应和发音抑制。该模型能更好地解释双任务表现和主动加工。
Brain scans support the distinction between the components, showing activation in different cortical areas during verbal and spatial tasks. However, the central executive remains vague and difficult to test experimentally.
脑部扫描支持各成分之间的区分，显示言语和空间任务激活了不同皮层区域。然而，中央执行系统的定义依然模糊，且难以通过实验检验。
5. Cognitive Psychology: Eyewitness Testimony | 认知心理学：目击证人证词
Eyewitness testimony refers to memory accounts given by witnesses to a crime. Loftus and Palmer (1974) investigated leading questions. In Experiment 1, participants estimated higher speeds when the verb ‘smashed’ was used compared to ‘contacted’. In Experiment 2, the ‘smashed’ group was more likely to report seeing broken glass a week later, demonstrating the misinformation effect.
目击证人证词指犯罪目击者提供的记忆陈述。Loftus 和 Palmer (1974) 研究了引导性问题。在实验 1 中，当使用动词 ‘smashed’ 时，参与者估计的车速显著高于使用 ‘contacted’ 的情况。在实验 2 中，’smashed’ 组在一周后更可能报告看到碎玻璃，表明了误导信息效应。
Schema theory explains that memories are reconstructed based on prior knowledge and expectations. When original memory traces are weak, post-event information can be integrated into the memory, distorting recall. This has serious implications for the reliability of eyewitness accounts in court.
图式理论解释，记忆是基于先验知识和期望重构的。当原始记忆痕迹薄弱时，事后信息会被整合入记忆，扭曲回忆。这对法庭上目击证词的可信度具有重要影响。
The cognitive interview, developed by Fisher and Geiselman (1992), improves recall by using context reinstatement, reporting everything, recalling in different orders and from different perspectives. It draws on principles of retrieval cues and context-dependent memory.
Fisher 和 Geiselman (1992) 开发的认知访谈通过恢复情境、报告一切、以不同顺序和不同视角回忆来改善回忆。它利用了提取线索和情境依赖记忆的原理。
6. Social Psychology: Obedience and Conformity | 社会心理学：服从与从众
Obedience is the act of following orders from an authority figure. Milgram’s (1963) shock study found that 65% of participants administered the maximum 450V shock to a confederate. This was explained by an agentic state, where individuals see themselves as agents of authority, and legitimate authority requiring an institutional context.
服从是遵循权威人物命令的行为。Milgram (1963) 的电击实验发现 65% 的参与者对同盟者施加了最高 450V 电击。这被解释为代理状态（个体视自己为权威的代理人）和合法权威需要一个制度情境。
Conformity refers to changing one’s behaviour or beliefs to match those of a group. Asch (1951) demonstrated normative social influence: on 37% of critical trials, participants conformed to an obviously wrong majority judgement about line length. Group size, unanimity and task difficulty are key variables.
从众指改变自身行为或信念以匹配群体。Asch (1951) 展示了规范社会影响：在 37% 的关键试次中，参与者屈从于明显错误的大众关于线段长度的判断。群体规模、一致性和任务难度是关键变量。
Both obedience and conformity are influenced by cultural norms. Smith and Bond (1998) found that collectivist cultures tend to show higher conformity rates. Additionally, situational explanations have been criticised for underestimating personality factors such as locus of control and empathy.
服从与从众均受文化规范影响。Smith 和 Bond (1998) 发现集体主义文化通常表现出更高的从众率。此外，情境解释因低估控制点、共情等人格因素而受到批评。
7. Developmental Psychology: Attachment | 发展心理学：依恋
Attachment is a deep emotional bond with a primary caregiver. Bowlby’s (1969) monotropic theory argued that infants have an innate drive to form one primary attachment, which provides a template for later relationships (internal working model). The critical period for attachment formation is within the first 2.5 years.
依恋是与主要照料者之间深厚的情感纽带。Bowlby (1969) 的单一依恋理论主张，婴儿具有形成一种首要依恋的先天驱力，该依恋提供日后关系的内在工作模型。依恋形成的关键期在 2.5 岁以内。
Ainsworth’s (1978) Strange Situation identified three attachment types: secure (Type B), insecure-avoidant (Type A) and insecure-resistant (Type C). Secure attachment correlates with sensitive mothering, whereas insecure patterns are linked to inconsistent or rejecting caregiving. The procedure has high reliability but may lack cross-cultural validity.
Ainsworth (1978) 的陌生情境识别出三种依恋类型：安全型 (B 型)、不安全-回避型 (A 型) 和不安全-反抗型 (C 型)。安全型依恋与敏感的母亲照护相关，而不安全模式与不一致或拒绝性看护相关。该程序信度高但可能缺乏跨文化效度。
Cross-cultural research by Van IJzendoorn and Kroonenberg (1988) found secure attachment is the most common across cultures, but differences in distribution of insecure types exist. This supports attachment as a universal phenomenon while recognising cultural variations in caregiving practices.
Van IJzendoorn 和 Kroonenberg (1988) 的跨文化研究发现安全型依恋在各文化中最为普遍，但不安全类型的分布存在差异。这既支持依恋是普遍现象，也承认了照料实践的文化变异。
8. Individual Differences: Intelligence and Personality | 个体差异：智力与人格
Intelligence has been defined in many ways. Spearman (1904) proposed a general factor (g) underpinning all mental abilities, whereas Gardner (1983) proposed eight distinct intelligences. IQ tests measure intelligence quantitatively but have been criticised for cultural bias and for ignoring creative and practical skills.
智力有多种定义方式。Spearman (1904) 提出了支撑所有心智能力的普遍因素 (g)，而 Gardner (1983) 提出了八种不同的智能。IQ 测试以量化方式测量智力，但因存在文化偏见以及忽略创造性和实践技能而受到批评。
The Big Five personality model (Costa & McCrae, 1992) describes personality on five dimensions: openness, conscientiousness, extraversion, agreeableness and neuroticism (OCEAN). Eysenck’s PEN model condenses personality into psychoticism, extraversion and neuroticism, linking them to biological bases like cortical arousal.
大五人格模型 (Costa & McCrae, 1992) 用五个维度描述人格：开放性、尽责性、外向性、宜人性和神经质 (OCEAN)。Eysenck 的 PEN 模型将人格浓缩为精神质、外向性和神经质，并将其与皮层唤醒等生物基础联系起来。
Measuring personality often relies on self-report questionnaires such as the EPQ. While they are easy to administer, they are vulnerable to social desirability bias and demand characteristics. Psychodynamic theorists argue these trait approaches neglect unconscious processes.
测量人格通常依赖自我报告问卷，如 EPQ。虽然易于施测，但这些问卷易受社会称许性偏差和需求特征的影响。精神动力学理论家认为这些特质取向忽略了无意识过程。
9. Health Psychology: Stress and Coping | 健康心理学：压力与应对
Stress is a physiological and psychological response to perceived threats. The fight-or-flight response involves activation of the sympathetic adrenal-medullary (SAM) pathway, releasing adrenaline. Chronic stress activates the hypothalamic-pituitary-adrenal (HPA) axis, raising cortisol levels, which can impair immune function.
压力是对感知到的威胁的生理及心理反应。战斗或逃跑反应涉及交感-肾上腺髓质 (SAM) 通路激活，释放肾上腺素。慢性压力激活下丘脑-垂体-肾上腺 (HPA) 轴，升高皮质醇水平，可能损害免疫功能。
Kiecolt-Glaser et al. (1984) found that medical students had lower natural killer cell activity during examination periods, indicating exam stress reduces immune function. This supports a direct link between psychological stress and physical health, though individual differences in coping were not fully controlled.
Kiecolt-Glaser 等人 (1984) 发现医学生在考试期间自然杀伤细胞活性降低，表明考试压力降低了免疫功能。这支持心理压力与身体健康的直接联系，尽管应对方式的个体差异未完全控制。
Transactional model of stress (Lazarus & Folkman, 1984) emphasises cognitive appraisal: primary appraisal evaluates threat, secondary appraisal evaluates coping resources. Problem-focused coping tackles stressors directly, while emotion-focused coping manages emotional distress. The model suggests stress is subjective and modifiable through cognitive reappraisal.
压力交互模型 (Lazarus & Folkman, 1984) 强调认知评估：初级评估评判威胁，次级评估评判应对资源。问题聚焦应对直接处理压力源，而情绪聚焦应对管理情绪困扰。该模型表明压力是主观的，可通过认知重评予以调整。
10. Issues and Debates in Psychology | 心理学议题与争论
The nature-nurture debate explores whether behaviour is determined by heredity or environment. Adoption and twin studies suggest most traits result from an interaction. For example, intelligence has a heritability estimate of around 0.5, indicating substantial environmental input despite genetic influence.
天性-教养争论探讨行为是由遗传还是环境决定。收养研究和双生子研究表明大多数特质是相互作用的结果。例如，智力的遗传率估计约 0.5，表明尽管有遗传影响，环境输入仍很显著。
Reductionism breaks behaviour into simplest components, as seen in explanations of neurotransmitters in mental illness. Holism considers the whole person and social context, exemplified by the biopsychosocial model. While reductionist approaches are more scientifically testable, they may oversimplify complex behaviours.
还原论将行为分解为最简单的成分，如用神经递质解释心理疾病。整体论考虑完整的人和社会情境，如生物心理社会模型所示。虽然还原论取向更具科学可检验性，但可能过度简化复杂行为。
Psychology must address cultural bias. WEIRD samples (Western, Educated, Industrialised, Rich, Democratic) dominate research, reducing generalisability. Cross-cultural studies, such as those on attachment or conformity, highlight both universals and culture-specific patterns, supporting an etic-emic distinction.
心理学必须解决文化偏见。WEIRD 样本（西方、受过教育、工业化、富裕、民主）主导研究，降低了可推广性。关于依恋或从众的跨文化研究既揭示了普适性也凸显了文化特定模式，支持主位-客位区分。
