1. Introduction to Psychology and Research Methods | 心理学导论与研究方法
Psychology is the scientific study of mind and behaviour, using systematic methods to collect data and test hypotheses.
心理学是对心理和行为的科学研究，它使用系统的方法来收集数据并检验假设。
The independent variable (IV) is manipulated by the researcher, while the dependent variable (DV) is measured to see the effect of the IV.
自变量 (IV) 由研究者操纵，而因变量 (DV) 被测量以观察自变量的效应。
Experimental designs include independent groups (different participants in each condition), repeated measures (same participants in all conditions), and matched pairs (participants matched on key characteristics).
实验设计包括独立组设计（不同参与者处于不同条件）、重复测量设计（相同参与者经历所有条件）和配对组设计（参与者在关键特征上进行匹配）。
Standardised procedures and controls are vital to minimise extraneous variables, ensuring that results are valid and reliable.
标准化程序和控制措施对于最小化额外变量至关重要，从而确保结果的有效性和可靠性。
Ethical guidelines require informed consent, protection from harm, the right to withdraw, confidentiality, and debriefing of participants.
伦理准则要求获得知情同意、保护参与者免受伤害、允许随时退出、保密以及事后解释。
2. Biological Psychology: Brain and Behaviour | 生物心理学：大脑与行为
The nervous system is divided into the central nervous system (brain and spinal cord) and the peripheral nervous system, which relays messages between the CNS and the body.
神经系统分为中枢神经系统（脑和脊髓）和周围神经系统，周围神经系统在中枢神经系统与身体之间传递信息。
Neurons communicate through electrical impulses; a synapse is the gap between neurons where neurotransmitters carry the signal.
神经元通过电脉冲进行交流；突触是神经元之间的间隙，神经递质在此处传递信号。
The frontal lobe is responsible for decision-making and personality, the temporal lobe for auditory processing, the occipital lobe for vision, and the parietal lobe for sensory integration.
额叶负责决策和人格，颞叶负责听觉加工，枕叶负责视觉，顶叶负责感觉整合。
The case of Phineas Gage, who suffered frontal lobe damage, provided early evidence for localisation of function in the brain.
菲尼亚斯·盖奇的额叶受损案例为大脑功能定位提供了早期证据。
Hormones such as adrenaline are secreted by the endocrine system and can influence behaviour, for example by triggering the fight-or-flight response.
肾上腺素等激素由内分泌系统分泌，能够影响行为，例如触发战斗或逃跑反应。
3. Sensation and Perception | 感觉与知觉
Sensation refers to the detection of physical stimuli by sense organs, whereas perception is the brain's interpretation of those sensations, giving them meaning.
感觉是指感觉器官对物理刺激的检测，而知觉则是大脑对这些感觉的解读并赋予其意义。
Visual perception relies on rods, which detect light and dark, and cones, which are responsible for colour vision and detail.
视觉依赖于视杆细胞和视锥细胞，视杆细胞检测明暗，视锥细胞负责颜色视觉和细节。
Gestalt principles of perceptual organisation include similarity (grouping similar items), proximity (grouping nearby items), closure (filling in gaps), and continuity (preferring continuous patterns).
格式塔知觉组织原则包括相似性（将相似项目归类）、接近性（将邻近项目归类）、闭合性（填补缺口）和连续性（偏好连续模式）。
Depth perception uses monocular cues such as linear perspective and relative size, and binocular cues like retinal disparity.
深度知觉使用单眼线索如线条透视和相对大小，以及双眼线索如视网膜像差。
Perceptual set is the readiness to perceive something in a certain way, influenced by expectation and context, as demonstrated in ambiguous figure studies.
知觉定势是一种以特定方式感知事物的准备状态，受期望和背景的影响，在双歧图研究中得到验证。
4. Sleep and Dreaming | 睡眠与梦境
Sleep cycles consist of alternating NREM (non-rapid eye movement) stages and REM (rapid eye movement) sleep, which is associated with vivid dreaming.
睡眠周期由交替出现的非快速眼动睡眠阶段和快速眼动睡眠组成，后者与生动的梦境相关。
The restoration theory suggests that sleep is essential for repairing the body and brain, while the evolutionary theory argues that sleep conserves energy and keeps us safe at night.
恢复理论认为睡眠对于修复身体和大脑至关重要，而进化理论则认为睡眠可以节省能量并在夜间保护我们的安全。
Freud's wish-fulfilment theory proposed that dreams represent unconscious desires and conflicts, often disguised through symbolism.
弗洛伊德的愿望实现理论提出，梦境代表无意识的欲望和冲突，通常通过象征手法加以伪装。
The activation-synthesis model explains dreams as the brain's attempt to make sense of random neural activity during REM sleep.
激活-合成模型将梦解释为大脑试图理解快速眼动睡眠期间随机神经活动的结果。
Insomnia is a sleep disorder involving difficulty falling or staying asleep; narcolepsy is characterised by sudden sleep attacks during the day.
失眠是一种涉及难以入睡或保持睡眠的睡眠障碍；发作性睡病的特征则是白天突然出现睡眠发作。
5. Memory | 记忆
The multi-store model describes memory as consisting of sensory memory, short-term memory (STM) with limited capacity and duration, and long-term memory (LTM) with potentially unlimited storage.
多存储模型将记忆描述为由感觉记忆、容量和持续时间有限的短时记忆，以及潜在无限存储的长期记忆组成。
Encoding refers to the transformation of information into a form that can be stored; rehearsal helps transfer information from STM to LTM.
编码是指将信息转化为可存储形式的过程；复述有助于将信息从短时记忆转入长期记忆。
Forgetting can occur due to decay (memory traces fade over time) or interference, where new or old information disrupts recall (proactive and retroactive interference).
遗忘可能由于衰退（记忆痕迹随时间消退）或干扰而发生，新旧信息都会干扰回忆（前摄干扰和倒摄干扰）。
Peterson and Peterson's study showed that information in STM decays rapidly without rehearsal, with recall dropping to around 10% after 18 seconds.
彼得森和彼得森的研究表明，短时记忆中的信息在没有复述的情况下会迅速衰退，18秒后回忆率降至约10%。
Reconstructive memory suggests that recall is an active process influenced by schemas, which can lead to distortions, as shown in Bartlett's 'War of the Ghosts' study.
重构记忆表明回忆是一个主动过程，受到图式的影响，这可能导致扭曲，巴特利特的“幽灵之战”研究证实了这一点。
6. Learning and Conditioning | 学习与条件反射
Classical conditioning, discovered by Pavlov, involves learning through association where a neutral stimulus becomes a conditioned stimulus, eliciting a conditioned response.
巴甫洛夫发现的经典条件反射涉及通过联想进行学习，其中一个中性刺激变成条件刺激，引发条件反应。
Operant conditioning, studied by Skinner, explains how behaviour is shaped by consequences: reinforcement increases behaviour, while punishment decreases it.
斯金纳研究的操作性条件反射解释了行为如何被后果塑造：强化增加行为，惩罚减少行为。
Positive reinforcement adds a pleasant stimulus, negative reinforcement removes an unpleasant one; both strengthen the behaviour that preceded them.
正强化添加一个愉快的刺激，负强化移除一个不愉快的刺激；两者都会增强之前的行为。
Bandura's social learning theory emphasises that we learn by observing and imitating models, a process involving attention, retention, reproduction, and motivation.
班杜拉的社会学习理论强调我们通过观察和模仿榜样来学习，这个过程涉及注意、保持、复制和动机。
The Bobo doll experiment demonstrated that children imitated aggressive behaviour modelled by adults, especially when the model was rewarded.
波波玩偶实验表明，儿童会模仿成人榜样的攻击性行为，尤其是当榜样受到奖励时。
7. Developmental Psychology | 发展心理学
Piaget's theory of cognitive development outlines four stages: sensorimotor, preoperational, concrete operational, and formal operational, each characterised by different ways of thinking.
皮亚杰的认知发展理论划分了四个阶段：感觉运动阶段、前运算阶段、具体运算阶段和形式运算阶段，每个阶段以不同的思维方式为特征。
During the preoperational stage, children display egocentrism and lack conservation (the understanding that quantity remains the same despite changes in shape).
在前运算阶段，儿童表现出自我中心且缺乏守恒概念（即不理解数量在形状改变时保持不变）。
Ainsworth's 'Strange Situation' identified attachment types: secure, insecure-avoidant, and insecure-resistant, based on how infants respond to separation and reunion with their caregiver.
安斯沃斯的“陌生情境”实验根据婴儿对与照顾者分离和重聚的反应，识别出依恋类型：安全型、不安全-回避型和不安全-矛盾型。
Bowlby's theory proposed that attachment is an innate behaviour that evolved to keep infants close to caregivers for survival, and that early attachments form an internal working model for future relationships.
鲍尔比的理论提出，依恋是一种与生俱来的行为，进化上是为了让婴儿接近照顾者以求生存，且早期依恋会形成未来人际关系的内在运作模式。
8. Social Influence: Conformity and Obedience | 社会影响：从众与服从
Conformity is a change in behaviour or belief to match a group norm; Asch's line study revealed that many participants conformed to an obviously incorrect majority to avoid social rejection.
从众是指行为或信念的改变以符合群体规范；阿希的线段实验显示，许多参与者会依从明显错误的多数以避免被社会排斥。
Normative social influence occurs when we conform to be liked and accepted, while informational social influence happens when we conform because we believe the group is right.
规范性社会影响发生在我们为了被喜欢和接纳而从众时，而信息性社会影响发生在我们因为相信群体是正确的而从众时。
Obedience to authority was demonstrated in Milgram's electric shock experiments, where ordinary people followed orders to administer what they believed were painful shocks.
米尔格拉姆的电击实验展示了对权威的服从，实验中普通人服从指令，施加了他们认为是痛苦的电击。
Factors affecting obedience included the proximity of the authority figure, the legitimacy of the setting, and the presence of disobedient peers.
影响服从的因素包括权威人物的接近程度、环境的合法性以及出现不服从同伴的情况。
The bystander effect refers to the finding that people are less likely to help in an emergency when others are present, due to diffusion of responsibility.
旁观者效应指的是在有其他人在场时，人们更不愿意在紧急情况下提供帮助的现象，这是因为责任分散。
9. Language, Thought and Communication | 语言、思维与沟通
Language is structured in terms of phonemes (basic sounds), morphemes (smallest units of meaning), and grammar (rules for combining words).
语言的结构可以从音素（基本声音）、词素（最小的意义单位）和语法（组合词汇的规则）来分析。
Chomsky's nativist theory argues that humans are born with a language acquisition device (LAD) that enables rapid language learning.
乔姆斯基的天赋论主张，人类天生具有语言习得装置，这使得语言学习能够快速进行。
In contrast, behaviourist explanations suggest that language is acquired through imitation, reinforcement, and association with caretakers.
与此相对，行为主义的解释则认为语言是通过模仿、强化以及与看护者的关联而习得的。
Problem solving can involve algorithms (step-by-step procedures guaranteeing a correct solution) or heuristics (mental shortcuts that are faster but may lead to errors).
问题解决可以使用算法（保证正确解决方案的逐步程序）或启发式（更快但可能导致错误的心理捷径）。
Mental set is a tendency to approach problems using methods that worked in the past, which can sometimes block insight and hinder finding a simpler solution.
心理定势是一种倾向于用过去奏效的方法来解决问题的倾向，这有时会阻碍顿悟，妨碍找到更简单的解决方案。
10. Psychological Problems: Mental Health | 心理问题：心理健康
Mental health problems involve significant disturbances in thoughts, feelings, or behaviours; schizophrenia, depression, and obsessive-compulsive disorder (OCD) are key examples studied in GCSE psychology.
心理健康问题涉及思维、情感或行为的显著紊乱；精神分裂症、抑郁症和强迫症是 GCSE 心理学研究的典型案例。
The biological explanation of depression points to low levels of serotonin; psychological explanations include Beck's cognitive theory of negative thinking patterns.
抑郁症的生物学解释指出血清素水平偏低；心理学解释则包括贝克关于消极思维模式的认知理论。
OCD is characterised by obsessions (recurring intrusive thoughts) and compulsions (repetitive behaviours performed to reduce anxiety).
强迫症的特征是强迫观念（反复出现的侵入性思维）和强迫行为（为了减轻焦虑而进行的重复性行为）。
Treatments for mental disorders range from biological interventions like antidepressant drugs (SSRIs) to psychological therapies such as cognitive behavioural therapy (CBT), which aims to change maladaptive thoughts and behaviours.
精神障碍的治疗方法包括生物学干预（如抗抑郁药物 SSRIs）和心理治疗（如认知行为疗法 CBT），其目标是改变不良的思维和行为模式。
Ethical considerations in diagnosis include the risk of labelling and stigmatisation; cultural variations also affect how symptoms are expressed and interpreted.
诊断中的伦理考量包括贴标签和污名化的风险；文化差异也会影响症状的表达和解读方式。
