1. Understanding Research Methods | 理解研究方法
Psychology is a science that relies on empirical evidence. Researchers use experiments, observations, interviews and questionnaires to test hypotheses. An experiment is the most powerful method for establishing cause and effect because it involves the manipulation of an independent variable (IV) while measuring the dependent variable (DV).
心理学是一门依赖实证证据的科学。研究者使用实验、观察、访谈和问卷来检验假设。实验是建立因果关系最有力的方法，因为它涉及操纵自变量 (IV) 并测量因变量 (DV)。
The independent variable (IV) is the factor that is deliberately changed or manipulated by the experimenter. The dependent variable (DV) is the factor that is measured to see if it is affected by changes in the IV. Extraneous variables are any other factors that could influence the DV and must be controlled to ensure validity.
自变量 (IV) 是实验者有意改变或操纵的因素。因变量 (DV) 是被测量以观察它是否受 IV 变化影响的因素。额外变量是任何可能影响 DV 的其他因素，必须加以控制以确保效度。
There are three main experimental designs: independent groups, repeated measures and matched pairs. In an independent groups design, different participants are used in each condition. This avoids order effects but requires more participants and may be affected by participant differences. Repeated measures use the same participants in all conditions, which controls participant variables but creates order effects such as practice or fatigue. Matched pairs involve pairing participants on key characteristics and then assigning each member to a different condition.
主要有三种实验设计：独立组设计、重复测量设计和匹配对设计。在独立组设计中，不同条件使用不同的参与者。这避免了顺序效应，但需要更多参与者且可能受个体差异影响。重复测量在所有条件中使用相同的参与者，控制了参与者变量，但会产生顺序效应，如练习或疲劳。匹配对设计根据关键特征对参与者配对，然后将每对中的个体分配到不同条件。
A hypothesis must be a precise, testable statement. A directional (one-tailed) hypothesis predicts the direction of the difference, e.g. ‘Participants will recall more words from a list when the words are organised than when they are unorganised.’ A non-directional (two-tailed) hypothesis simply predicts a difference without stating direction, e.g. ‘There will be a difference in recall between organised and unorganised word lists.’
假设必须是一个精确、可检验的陈述。定向（单尾）假设预测差异的方向，例如“参与者在单词有组织时会比无组织时回忆更多的词”。非定向（双尾）假设仅预测存在差异而不指明方向，例如“单词有组织与无组织条件下的回忆会有差异”。
Sampling techniques include random sampling, stratified sampling, volunteer sampling and opportunity sampling. Random sampling gives every member of the target population an equal chance of being selected, which reduces bias but can be difficult to achieve. Stratified sampling ensures subgroups are proportionally represented. Volunteer and opportunity samples are easier but more biased.
抽样技术包括随机抽样、分层抽样、志愿者抽样和机会抽样。随机抽样使目标人群中的每个成员都有相等机会被选中，减少偏差但难以实现。分层抽样确保子群体按比例代表。志愿者和机会抽样更容易但有更多偏差。
2. Ethical Considerations in Psychology | 心理学中的伦理考量
All psychological research must adhere to strict ethical guidelines to protect participants. The British Psychological Society (BPS) sets out principles including informed consent, right to withdraw, deception, debriefing, confidentiality and protection from harm. Informed consent means participants should know the aim and procedures before agreeing to take part. If full consent cannot be gained, presumptive consent or retrospective consent may be used.
所有心理学研究都必须遵守严格的伦理准则以保护参与者。英国心理学会 (BPS) 制定了包括知情同意、退出权、欺骗、事后说明、保密和保护免受伤害的原则。知情同意意味着参与者在同意参加前应知道目的和程序。如果无法获得完全同意，可以使用假定同意或追溯同意。
Deception should be avoided unless it is necessary and justified. When deception is used, researchers must debrief participants afterwards, explaining the true purpose and offering the chance to withdraw their data. The right to withdraw means participants can leave the study at any time without penalty. Confidentiality requires that personal data is anonymised and stored securely.
欺骗应避免，除非必要且合理。若使用欺骗，研究者必须事后向参与者进行说明，解释真实目的并提供撤回数据的机会。退出权意味着参与者可以随时离开研究而不受惩罚。保密要求个人数据匿名并安全储存。
Protection from harm is crucial; psychological or physical distress must be no greater than what is encountered in everyday life. In socially sensitive research, the researcher must also consider the impact on the wider community. Ethical issues have been particularly discussed in classic studies such as Milgram’s obedience experiment.
保护免受伤害至关重要；心理或身体的不适应不超过日常生活中遇到的程度。在社会敏感性研究中，研究者还必须考虑对更广泛社群的影响。伦理问题在经典研究如米尔格拉姆的服从实验中得到了特别讨论。
3. Memory: Models and Key Studies | 记忆：模型与关键研究
The multi-store model (MSM) proposed by Atkinson and Shiffrin (1968) describes memory as consisting of three stores: sensory register, short-term memory (STM) and long-term memory (LTM). Information enters the sensory register through the senses; if attention is paid, it passes to STM. Through rehearsal, information can be transferred to LTM. The model highlights the limited capacity and duration of STM.
阿特金森和希夫林 (1968) 提出的多存储模型 (MSM) 将记忆描述为由感觉登记器、短时记忆 (STM) 和长时记忆 (LTM) 三个存储组成。信息通过感官进入感觉登记器；若被注意，则进入 STM。通过复述，信息可转入 LTM。该模型强调 STM 的容量和持续时间有限。
Peterson and Peterson (1959) investigated the duration of STM. They gave participants trigrams (e.g., KPL) and then a distractor task of counting backwards in threes to prevent rehearsal. After intervals of 3, 6, 9, 12, 15 or 18 seconds, recall was tested. Recall dropped dramatically after 18 seconds, suggesting STM duration is about 18–30 seconds without rehearsal. This study used a laboratory experiment, which gives high control but lacks mundane realism.
彼得森夫妇 (1959) 研究了 STM 的持续时间。他们给参与者三字母组（如 KPL），然后要求进行倒减三的干扰任务以防止复述。在间隔 3、6、9、12、15 或 18 秒后测试回忆。18 秒后回忆急剧下降，表明在无复述时 STM 持续时间约为 18-30 秒。该研究采用实验室实验，控制程度高但缺乏世俗真实性。
Bartlett (1932) introduced the idea of reconstructive memory. He used the story ‘The War of the Ghosts’ and found that over repeated reproductions, the story became shorter, more coherent and fitted participants’ own cultural schemas. This shows that memory is not a passive copy but an active reconstruction influenced by past experience and expectations. However, his method was informal and lacked standardised procedures.
巴特利特 (1932) 提出了重构记忆的概念。他使用故事“幽灵之战”，发现经过反复复述，故事变得更短、更连贯，符合参与者自身的文化图式。这表明记忆不是被动复制，而是受过去经验和期望影响的主动重构。然而，他的方法非正式，缺乏标准化程序。
Coding, capacity and duration can be compared across stores. STM tends to code acoustically, has a capacity of about 7±2 items and duration around 18 seconds. LTM codes semantically, has potentially unlimited capacity and lifetime duration. Serial position effects support the MSM, with primacy effect reflecting LTM and recency effect reflecting STM.
对编码、容量和持续时间可以跨存储进行比较。STM 倾向于声学编码，容量约 7±2 个项目，持续时间约 18 秒。LTM 是语义编码，容量几乎无限，持续时间为终生。系列位置效应支持 MSM，首因效应反映 LTM，近因效应反映 STM。
4. Developmental Psychology: Piaget and Attachment | 发展心理学：皮亚杰与依恋
Piaget’s theory of cognitive development proposes that children pass through four stages: sensorimotor (0-2 years), pre-operational (2-7 years), concrete operational (7-11 years) and formal operational (11+ years). In the pre-operational stage, children are egocentric and lack conservation – they cannot understand that quantity remains the same despite changes in appearance.
皮亚杰的认知发展理论提出儿童经历四个阶段：感知运动阶段（0-2 岁）、前运算阶段（2-7 岁）、具体运算阶段（7-11 岁）和形式运算阶段（11+ 岁）。在前运算阶段，儿童以自我为中心，缺乏守恒——他们不能理解数量尽管外观改变仍保持不变。
Piaget’s conservation of number task involved rows of counters. When one row was spread out, pre-operational children said there were more counters, showing centration and an inability to conserve. His liquid conservation task showed similar errors. These studies demonstrated that children’s thinking is qualitatively different from adults’. However, McGarrigle and Donaldson (1974) showed that when the change appears accidental, children can conserve, suggesting Piaget underestimated children’s abilities.
皮亚杰的数量守恒任务涉及几行棋子。当一行被间隔开，前运算阶段的儿童说棋子变多了，表现出中心化和守恒能力不足。他的液体守恒任务显示了类似错误。这些研究说明儿童的思维与成人有质的差别。但麦加里格和唐纳森 (1974) 表明，当变化看似意外时，儿童能够守恒，提示皮亚杰可能低估了儿童的能力。
Attachment is an emotional bond between infant and caregiver. Bowlby argued that attachment has a biological basis and that a child needs one primary attachment figure (monotropy) for healthy social and emotional development. The critical period hypothesis suggests that if attachment does not form within the first 2.5 years, it may never fully develop.
依恋是婴儿与照料者之间的情感纽带。鲍尔比认为依恋有生物学基础，儿童需要一个主要依恋对象（单一依恋）以促进社会性和情感的健康发展。关键期假说指出，如果在前 2.5 年内没有形成依恋，可能永远无法完全发展。
Ainsworth’s ‘Strange Situation’ assessed attachment types. Infants were observed in a series of separations and reunions with their caregiver. Three types were identified: secure (anxious-resistant), insecure-avoidant and insecure-ambivalent. Securely attached infants use the caregiver as a safe base and are easily comforted. This study used structured observation and cross-cultural research, but critics note it may be ethnocentric, reflecting Western norms.
艾恩斯沃斯的“陌生情境”评估了依恋类型。观察婴儿在一系列与照料者的分离和重聚中的反应。划分出三种类型：安全型、不安全-回避型和不安全-矛盾型。安全型依恋的婴儿把照料者当作安全基地且容易安抚。这项研究使用了结构化观察和跨文化研究，但批评者指出它可能以西方为中心，反映了西方规范。
Bandura’s (1961) Bobo doll experiment demonstrated that children learn aggressive behaviour through observation and imitation of role models. Children who watched an adult model act aggressively towards the doll were more likely to imitate that aggression, especially when the model was of the same sex. This supports social learning theory, which emphasises the role of modelling and vicarious reinforcement in development.
班杜拉 (1961) 的波波玩偶实验表明儿童通过观察和模仿榜样学习攻击行为。看到成年榜样对玩偶实施攻击的儿童更可能模仿这种攻击，尤其当榜样与儿童同性别时。这支持了社会学习理论，强调榜样和替代强化在发展中的作用。
5. Social Influence: Conformity and Obedience | 社会影响：从众与服从
Conformity is a change in behaviour or belief due to real or imagined group pressure. Asch (1951) conducted a line judgement task where naive participants were placed in groups with confederates who unanimously gave wrong answers. About 75% conformed at least once, and the average conformity rate was 37%. This shows the power of normative social influence, the desire to fit in and avoid rejection. Informational social influence occurs when we conform because we believe the group has more knowledge.
从众是由于真实或想象到的群体压力而导致的行为或信念改变。阿希 (1951) 进行了线段判断任务，将不知情的参与者置于一群都一致给出错误答案的假被试中。约 75% 的人至少从众过一次，平均从众率 37%。这显示了规范性社会影响的力量，即渴望被接纳、避免拒绝。信息性社会影响发生在我们因相信群体拥有更多知识而从众时。
Factors affecting conformity include group size, unanimity and task difficulty. Conformity increases when the group has three or more members, but beyond four the effect plateaus. If even one confederate gives the correct answer, conformity drops sharply. Asch’s paradigm has been criticised as a ‘child of its time’ – conformity rates were lower in replications, possibly because the 1950s America was highly conformist.
影响从众的因素包括群体大小、一致性和任务难度。当群体有三人或以上时从众增加，但超过四人后效果趋于稳定。如果哪怕有一个假被试给出正确答案，从众就急剧下降。阿希的范式被批评为“时代的产物”——在重复实验中从众率较低，可能是因为 1950 年代的美国高度强调一致。
Obedience is following direct orders from an authority figure. Milgram (1963) recruited participants for a ‘learning experiment’ where they were instructed to give electric shocks to a learner (confederate) for wrong answers. The shock levels increased to a dangerous 450V. Despite the learner’s protests, 65% of participants went to the maximum voltage. This study reveals the strong power of an authority figure and the agentic state, where individuals shift responsibility to the person giving orders.
服从是遵从权威人物直接发出的指令。米尔格拉姆 (1963) 招募参与者参加一项“学习实验”，他们被指示在学习者（假被试）答错时实施电击。电击水平增加到危险的 450V。尽管学习者抗议，65% 的参与者还是达到了最大电压。这项研究揭示了权威人物的强大力量以及代理人状态，即个体将责任转移给发号施令者。
Milgram’s experiment raised major ethical concerns: deception, lack of informed consent, and extreme distress. However, debriefing showed that most participants were glad they had participated. Situational factors such as proximity of the victim, prestige of the setting and presence of disobedient peers significantly affected obedience levels. Proximity of the authority figure (closeness of the experimenter) also made a difference.
米尔格拉姆的实验引发了重大的伦理关切：欺骗、缺乏知情同意以及极度痛苦。但事后说明表明大多数参与者为自己参与了实验而高兴。情境因素，如受害者的接近程度、实验场所的威望以及有不服从同伴在场，显著影响服从水平。权威人物的接近程度（实验者的距离）也有影响。
6. Biological Psychology: The Brain and Nervous System | 生物心理学：大脑与神经系统
The nervous system is divided into the central nervous system (CNS) – brain and spinal cord – and the peripheral nervous system (PNS) which connects the CNS to the rest of the body. The PNS is further split into the somatic nervous system (voluntary control) and the autonomic nervous system (involuntary control). The autonomic system includes the sympathetic branch (fight or flight) and the parasympathetic branch (rest and digest).
神经系统分为中枢神经系统 (CNS)——即脑和脊髓——以及外周神经系统 (PNS)，后者将 CNS 与身体其他部分连接起来。PNS 进一步分为躯体神经系统（随意控制）和自主神经系统（非随意控制）。自主系统包括交感分支（战斗或逃跑）和副交感分支（休息与消化）。
Neurons are specialised cells that transmit electrical and chemical signals. Sensory neurons carry information from receptors to the CNS, motor neurons carry impulses from the CNS to effectors (muscles, glands) and relay neurons connect sensory and motor neurons within the CNS. A synapse is the junction where neurotransmitters are released to send signals from one neuron to the next.
神经元是传递电信号和化学信号的特化细胞。感觉神经元将信息从受体传导到 CNS，运动神经元将冲动从 CNS 传导到效应器（肌肉、腺体），联络神经元在 CNS 内连接感觉和运动神经元。突触是神经元间通过释放神经递质传递信号的连接点。
Brain scanning techniques such as fMRI, EEG and CT scans have advanced our understanding of brain structure and function. Damage to specific areas can be studied through case studies, like the famous case of Phineas Gage, who suffered frontal lobe damage and underwent dramatic personality changes, indicating the frontal lobes’ role in impulse control and social behaviour.
脑部扫描技术如功能性磁共振成像 (fMRI)、脑电图 (EEG) 和计算机断层扫描 (CT) 推进了我们对脑结构和功能的理解。通过个案研究可了解特定脑区的损伤，例如著名的菲尼亚斯·盖奇案例，他的额叶受损后人格发生了剧变，表明额叶在冲动控制和社会行为方面的作用。
The role of genetics in behaviour can be investigated through twin studies. Monozygotic (identical) twins share 100% of their genes, while dizygotic (fraternal) twins share about 50%. If a trait is more concordant in MZ twins than DZ twins, a genetic influence is suggested. This has been used to study intelligence, mental disorders and personality. However, twin studies cannot completely separate nature and nurture because MZ twins are often treated more similarly.
基因在行为中的作用可通过双胞胎研究来探索。同卵 (MZ) 双胞胎共享 100% 基因，而异卵 (DZ) 双胞胎共享约 50% 的基因。若某一特质在同卵双胞胎中表现出更高的一致性，则提示有遗传影响。这已用于研究智力、精神障碍和人格。然而，双胞胎研究无法完全分离先天与后天，因为同卵双胞胎往往被更相似地对待。
7. Individual Differences: Personality and Mental Health | 个体差异：人格与心理健康
Personality can be defined as the consistent and enduring patterns of thinking, feeling and behaving that make an individual unique. Eysenck’s personality theory proposes three dimensions: extraversion–introversion, neuroticism–stability and psychoticism–normality. Extraverts are sociable and stimulation-seeking, while introverts are quieter and prefer solitary activities. Neurotic individuals tend to be anxious and moody.
人格可定义为使个体独一无二的那些稳定持久的思维、情感和行为模式。艾森克的人格理论提出三个维度：外向–内向、神经质–稳定和精神质–正常。外向者社交活跃、寻求刺激，内向者较安静、喜欢独处。高神经质的人往往焦虑、情绪化。
Measuring personality often uses self-report inventories such as the Eysenck Personality Questionnaire (EPQ). These have the advantage of being easy to administer and allowing comparison across large groups. However, they rely on honest self-assessment and can be affected by social desirability bias, where participants answer in ways that make them look good.
测量人格常使用自陈问卷，如艾森克人格问卷 (EPQ)。其优点是容易实施，便于大样本比较。但它们依赖诚实的自我评价，并可能受社会赞许性偏差的影响，即参与者以展现自己良好形象的方式作答。
Abnormality can be defined in several ways: statistical infrequency, deviation from social norms, failure to function adequately and deviation from ideal mental health. Each definition has strengths and limitations. For example, statistical infrequency ignores the desirability of the trait (high IQ is statistically rare but not abnormal). Deviation from social norms is culture-bound and changes over time.
对异常的界定有多种方式：统计罕见性、对社会规范的偏离、功能丧失和对理想心理健康的偏离。每种定义都各有优缺。例如，统计罕见性忽略了特质的可取性（高智商统计上罕见但不被视为异常）。偏离社会规范受文化限制且随时间改变。
Schizophrenia and depression are two mental disorders studied at GCSE. Schizophrenia involves hallucinations, delusions and disorganised thinking. Biological explanations point to excess dopamine activity (the dopamine hypothesis), while psychological explanations highlight family dysfunction and stressful life events. Depression is characterised by persistent low mood, loss of interest and negative thinking. Beck’s cognitive triad explains depression as negative views of self, world and future.
精神分裂症和抑郁症是 GCSE 学习的两种障碍。精神分裂症包括幻觉、妄想和思维紊乱。生物解释指向多巴胺活动过度（多巴胺假说），心理解释则强调家庭功能障碍和压力生活事件。抑郁症特征为持续的情绪低落、兴趣丧失和消极思维。贝克的认知三联解释抑郁症为对自我、世界和未来的负面看法。
8. Sleep and Dreaming: Stages and Theories | 睡眠与梦：阶段与理论
Sleep follows a 90-minute cycle and comprises non-REM sleep (stages 1–4) and REM (rapid eye movement) sleep. Stage 1 is light sleep; stage 2 involves sleep spindles; stages 3 and 4 are slow-wave deep sleep, important for physical restoration. REM sleep is where vivid dreaming occurs, the brain is highly active and skeletal muscles are paralysed.
睡眠遵循 90 分钟周期，由非快速眼动睡眠（阶段 1-4）和快速眼动 (REM) 睡眠组成。阶段 1 是浅睡；阶段 2 出现睡眠纺锤波；阶段 3 和 4 是慢波深睡，对身体修复重要。REM 睡眠中会产生生动梦境，大脑高度活跃，骨骼肌处于麻痹状态。
The activation-synthesis theory (Hobson & McCarley, 1977) proposes that dreams result from the brain’s attempt to make sense of random neural signals generated in the brainstem during REM sleep. The forebrain synthesises these signals into a narrative, which explains why dreams feel bizarre but have some internal logic. The theory emphasises biological processes and denies that dreams have hidden meaning, in contrast to Freud’s wish-fulfilment theory.
激活-合成理论（霍布森与麦卡利，1977）提出，梦是大脑试图对 REM 睡眠期间脑干产生的随机神经信号赋予意义的结果。前脑将这些信号合成为叙事，这解释了为何梦境感觉怪诞但仍有一定内在逻辑。该理论强调生物过程，否认梦具有隐含意义，与弗洛伊德的愿望实现理论针锋相对。
Freud (1900) argued that dreams are the ‘royal road to the unconscious’ and contain manifest content (the storyline) and latent content (the hidden, symbolic meaning). For example, a dream about losing teeth might symbolise anxiety about powerlessness. Repressed wishes, often sexual or aggressive, are disguised as symbols. This theory is difficult to test scientifically and relies on subjective interpretation.
弗洛伊德 (1900) 认为梦是“通往潜意识的康庄大道”，包含显性内容（故事线）和隐性内容（隐藏的象征意义）。例如，梦见掉牙可能象征对无力感的焦虑。被压抑的愿望，常为性或攻击性，被伪装成符号。这一理论难以科学检验，依赖主观解释。
Sleep disorders include insomnia (difficulty falling or staying asleep) and narcolepsy (sudden, uncontrollable episodes of sleep). Understanding sleep has practical applications, such as improving sleep hygiene. For revision, remember the key differences between theories: biological versus psychological, nature of dreaming, and the evidence for each.
睡眠障碍包括失眠（难以入睡或保持睡眠）和发作性睡病（突然、不可控制的睡眠发作）。对睡眠的理解有实际应用，如改善睡眠卫生。复习时记住各理论的核心差异：生物与心理取向、梦的本质以及各自的支持证据。
9. Applying Research Methods: Designing an Investigation | 应用研究方法：设计一项调查
When you need to design a psychological study for the exam, you must be able to state a clear aim, formulate a testable hypothesis and identify your variables. Operationalising variables means making them measurable. For example, ‘aggression’ could be operationalised as the number of times a child hits a doll in a 10-minute session.
考试中需要设计一项心理学研究时，你必须能陈述明确的目的，形成可检验的假设，并识别出变量。操作化变量意味着使它们可测量。例如，“攻击性”可被操作为孩子在 10 分钟内击打玩具娃娃的次数。
Choose an appropriate experimental design and justify it by balancing control of variables and practical considerations. If you use independent groups, explain how you would randomly allocate participants and discuss how you would control participant variables, perhaps by using random assignment. For repeated measures, address counterbalancing to control order effects.
选择合适的实验设计，并通过对变量控制与实际考虑之间的权衡来论证它。若用独立组设计，要解释如何随机分配参与者，并讨论如何通过随机分配控制参与者变量。对于重复测量，要用平衡抵消法控制顺序效应。
You should suggest a suitable sampling method and explain how it would be carried out, along with ethical considerations. Always mention informed consent, debriefing and the right to withdraw. Think about potential extraneous variables (e.g., noise, time of day) and how to control them through standardised procedures.
你应提出合适的抽样方法，解释如何实施，并说明伦理考量。始终提及知情同意、事后说明和退出权。考虑潜在的额外变量（如噪音、时间点）以及如何通过标准化程序加以控制。
