1. Social Influence: Conformity and Obedience | 社会影响：从众与服从
Conformity is a change in behaviour or belief as a result of real or imagined group pressure. Asch’s line‑judgement study revealed that even in an unambiguous situation, participants conformed on 36.8% of critical trials, demonstrating normative social influence—the desire to fit in. Informational social influence occurs when we look to others for guidance in ambiguous situations, as shown by Jenness’s jellybean estimate task.
从众是指由于真实或想象中群体压力而导致的行为或信念改变。阿希的线条判断实验表明，即使在明确的情境下，参与者在关键试次中有 36.8% 从众，这体现了希望融入群体的规范性社会影响。信息性社会影响则发生在模糊情境中我们参照他人以获得指引时，詹尼斯通过糖果估数任务证明了这一点。
Obedience involves following direct commands from an authority figure. Milgram’s electric shock experiment found that 65% of participants administered the full 450 V, highlighting the power of the situation. Situational factors like proximity of the victim, location prestige, and uniform presence significantly reduced or increased obedience rates. Milgram proposed the agentic state theory: people shift responsibility to the authority, feeling no personal liability for their actions.
服从涉及听从权威人物的直接命令。米尔格拉姆的电击实验发现，65% 的参与者施加了最高 450 伏的电击，凸显了情境的力量。情境变量如受害者距离、地点声望和制服的有无，会显著降低或提高服从率。米尔格拉姆提出代理状态理论：人们将责任转移给权威，对自己行为不感到个人责任。
Explanations for resistance to social influence include social support—an ally reduces pressure to conform or obey—and locus of control. Individuals with an internal locus of control are more likely to resist pressure because they believe outcomes depend on their own actions. Minority influence, as studied by Moscovici, shows that a consistent minority can shift majority opinion through conversion, often leading to deeper processing of the message.
抵制社会影响的解释包括社会支持——有同伴在场可以降低从众或服从压力——以及控制点。内控型个体更有可能抵制压力，因为他们相信结果取决于自身行动。莫斯科维奇研究的少数派影响表明，始终如一的少数派可以通过转变效应改变多数人意见，且往往引发对信息的更深层加工。
2. Memory: Models and Forgetting | 记忆：模型与遗忘
The multi‑store model (Atkinson & Shiffrin) proposes three separate stores: sensory register, short‑term memory (STM), and long‑ rehearsed in a linear manner. Capacity of STM is 7±2 items (Miller), duration is about 18‑ ehearsal (Peterson & Peterson), while LTM has potentially unlimited capacity and duration.
多存储器模型（阿特金森和希夫林）提出三个独立存储器：感觉登记器、短期记忆（STM）和长期记忆（LTM）。信息通过注意传递并以线性方式复述。STM 容量约为 7±2 个组块（米勒），未经复述的持续时间约为 18–30 秒（彼得森夫妇），而 LTM 的容量和持续时间可能无限。
The working memory model (Baddeley & Hitch) challenges the idea of a single STM. It features a central executive that directs attention, a phonological loop processing verbal and auditory information, a visuospatial sketchpad for visual and spatial data, and an episodic buffer that integrates information into coherent episodes. Dual‑task studies support the existence of separate slave systems.
工作记忆模型（巴德利和希奇）挑战了单一 STM 的观点。该模型包含协调注意的中央执行器、处理言语和听觉信息的语音回路、处理视觉和空间信息的视空间画板，以及将信息整合为连贯情节的情景缓冲器。双任务研究支持了不同从属系统的存在。
Forgetting in STM occurs mainly through decay and displacement. In LTM, interference theory suggests proactive interference (older memories disrupt new ones) and retroactive interference (new learning disrupts old memories) are major causes. Retrieval failure occurs when context or state cues are absent—this is explained by the encoding specificity principle (Tulving).
STM 中的遗忘主要通过消退和替代发生。在 LTM 中，干扰理论认为前摄抑制（旧记忆干扰新记忆）和倒摄抑制（新学习干扰旧记忆）是主要原因。提取失败发生在情境线索或状态线索缺失时，这由编码特异性原则（托尔文）解释。
Eyewitness testimony is easily distorted by leading questions (Loftus & Palmer) and post‑event discussion. The cognitive interview technique improves recall by reinstating context, reporting everything, recalling in reverse order, and changing perspective. Anxiety can both enhance and impair memory accuracy depending on the situation—Yerkes‑Dodson law illustrates the inverted‑U relationship between arousal and performance.
目击者证词很容易被引导性问题（洛夫特斯和帕尔默）和事后讨论所扭曲。认知访谈技术通过恢复情境、报告一切、逆序回忆和改变视角来提高回忆准确度。焦虑对记忆准确性的影响会因情境而异——耶克斯‑多德森定律说明了唤醒水平与表现之间的倒 U 型关系。
3. Attachment: Types and Impact | 依恋：类型与影响
Attachment is a strong emotional bond between infant and caregiver that develops in stages. Schaffer and Emerson identified four phases: asocial, indiscriminate attachment, specific attachment, and multiple attachments. The primary attachment figure is usually the mother, but the person who responds most sensitively to the infant’s signals is most likely to become the attachment figure.
依恋是婴儿与照料者之间逐步形成的强烈情感纽带。谢弗和埃默森确定了四个阶段：非社交期、无差别依恋期、特定依恋期和多重依恋期。主要依恋对象通常是母亲，但对婴儿信号最敏感地回应的人最有可能成为依恋对象。
Animal studies by Lorenz (imprinting in goslings) and Harlow (rhesus monkeys preferring comfort over food) demonstrated the critical period for attachment and the importance of contact comfort. Bowlby’s monotropic theory argues infants have an innate drive to form one primary attachment, which serves as an internal working model for future relationships. The critical period is around 2.5 years; failure to form an attachment during this time leads to irreversible consequences.
洛伦兹（幼鹅的印刻现象）和哈洛（恒河猴偏爱舒适胜过食物）的动物研究证明了依恋的关键期以及接触舒适的重要性。鲍尔比的单一依恋理论认为，婴儿具有形成一种主要依恋的先天驱力，这将成为未来关系的内部工作模型。关键期约为 2.5 年，在此期间未能形成依恋会导致不可逆的后果。
Ainsworth’s Strange Situation classified infant attachment into secure (Type B), insecure‑avoidant (Type A), and insecure‑resistant (Type C). Maternal sensitivity is a key predictor: responsive, accessible caregivers tend to raise securely attached infants. Cultural variations exist, but secure attachment remains the most common across cultures. Van IJzendoorn and Kroonenberg’s meta‑analysis showed intra‑cultural differences are greater than inter‑cultural ones.
安斯沃思的陌生情境法将婴儿依恋分为安全型（B 型）、不安全‑回避型（A 型）和不安全‑反抗型（C 型）。母亲敏感性是关键预测因子：回应及时、易于接近的照料者更可能养育出安全型依恋的婴儿。虽然存在文化差异，但安全型依恋在各文化中均为最常见。范·伊茨多恩和克罗南伯格的元分析显示，文化内部差异大于文化间差异。
Romanian orphan studies by Rutter et al. compared children adopted before and after six months. Those adopted early showed normal emotional development, whereas late‑adopted children displayed disinhibited attachment, highlighting the long‑term effects of early deprivation. Early attachment experiences affect childhood relationships, adult romantic relationships, and even parenting style, as suggested by Hazan and Shaver’s love quiz.
鲁特等人对罗马尼亚孤儿的研究比较了六个月龄前和后被收养的儿童。早期被收养者表现出正常情绪发展，而后期收养者则出现去抑制化依恋，凸显了早期剥夺的长期影响。哈赞和谢弗的爱情问卷研究表明，早期依恋经历会影响童年友谊、成年恋爱关系甚至教养方式。
4. Psychopathology: Definitions and Treatments | 心理病理学：定义与治疗
Defining abnormality involves four main approaches: statistical infrequency (rare behaviours), deviation from social norms (behaviour that breaks accepted rules), failure to function adequately (Rosenhan & Seligman’s criteria), and deviation from ideal mental health (Jahoda’s six criteria). Each has limitations—for example, statistical infrequency fails to distinguish desirable and undesirable rare behaviours.
界定异常有四种主要方式：统计偏离（罕见行为）、偏离社会常模（违反公认规则的行为）、无法正常生活（罗森汉和塞利格曼的标准）以及偏离理想精神健康（贾霍达的六条标准）。每种方式都有局限——例如，统计偏离无法区分可取和不可取的罕见行为。
Phobias are characterised by excessive fear and anxiety triggered by objects or situations; they are explained by the two‑process model (acquisition by classical conditioning, maintenance by operant conditioning). Systematic desensitisation uses reciprocal inhibition to replace anxiety with relaxation, while flooding extinguishes the fear response by prolonged exposure to the feared stimulus without avoidance.
恐惧症的特征是由物体或情境引发的过度恐惧和焦虑，可用两过程模型（经典条件作用获得，操作性条件作用维持）解释。系统脱敏法利用交互抑制将焦虑替换为放松，而冲击疗法通过长时间暴露于恐惧刺激且不允许回避来消退恐惧反应。
) and Ellis’s ABC model (Activating event → Belief → Consequence) explain how faulty thinking causes depression. Cognitive‑ ese irrational beliefs, using techniques like thought catching and behavioural activation.
抑郁症涉及持续情绪低落、兴趣丧失和认知变化。贝克的认知三联征（对自我、世界和未来的负面看法）和埃利斯的 ABC 模型（激发事件→信念→后果）解释了错误思维如何导致抑郁。认知行为疗法（CBT）针对这些不合理信念，使用思维捕捉和行为激活等技术。
OCD features obsessions (intrusive thoughts) and compulsions (repetitive behaviours). Biological explanations point to the SERT gene and COMT gene affecting serotonin and dopamine levels, along with abnormal functioning in the orbitofrontal‑caudate neural loop. Drug therapies, primarily SSRIs, increase serotonin availability, while tricyclics like clomipramine act on multiple neurotransmitters.
强迫症以强迫思维（闯入性想法）和强迫行为（重复动作）为特征。生物学解释指向影响血清素和多巴胺水平的 SERT 基因和 COMT 基因，以及眶额‑尾状核神经回路的功能异常。药物治疗以 SSRIs 为主，提高血清素可用度，而氯米帕明等三环类药物作用于多种神经递质。
5. Approaches in Psychology | 心理学流派
The behaviourist approach focuses on observable behaviour and environmental determinants. Classical conditioning (Pavlov) explains how a neutral stimulus becomes associated with a reflex response, while operant conditioning (Skinner) explains behaviour through reinforcements and punishments. The approach has high scientific credibility but is reductionist—ignoring cognitive and emotional processes.
行为主义流派关注可观察行为和环境决定因素。经典条件作用（巴甫洛夫）解释了中性刺激如何与反射反应建立联系，而操作性条件作用（斯金纳）通过强化和惩罚来解释行为。该流派具有很高的科学可信度，但属于简化论——忽略了认知和情绪过程。
Social learning theory (Bandura) bridges behaviourism and cognitivism. It emphasizes observational learning, mediational processes (attention, retention, motor reproduction, motivation), and vicarious reinforcement. Bandura’s Bobo doll study showed children imitate aggressive models, especially when models are rewarded.
社会学习理论（班杜拉）连接了行为主义与认知主义。它强调观察学习、中介过程（注意、保持、动作再现、动机）和替代强化。班杜拉的波波玩偶研究显示儿童会模仿攻击性榜样，尤其当榜样受到奖励时。
The cognitive approach studies internal mental processes like perception, memory, and thinking. It uses theoretical models (e.g., information processing approach) and computer analogies to infer how the mind works. Schemas help us organise information but can lead to biases. Cognitive neuroscience combines cognitive psychology with brain imaging to link mental processes to neural activity.
认知流派研究知觉、记忆和思维等内部心理过程。它使用理论模型（例如信息加工方法）和计算机类比来推断心智的运作。图式有助于组织信息，但也可能导致偏见。认知神经科学将认知心理学与脑成像结合，将心理过程与神经活动联系起来。
The biological approach sees behaviour as rooted in genetics, neurotransmitters, brain structures, and evolution. Twin studies demonstrate the heritability of traits. Drug therapies targeting neurotransmitter systems support the approach’s practical applications. Biopsychology within this approach examines the nervous and endocrine systems.
生物流派认为行为根植于遗传、神经递质、脑结构和进化。双生子研究证明了特征的可遗传性。靶向神经递质系统的药物治疗支持了该流派的实际应用。此流派中的生物心理学研究神经和内分泌系统。
Psychodynamic and humanistic approaches offer contrasting perspectives. Freud’s psychodynamic theory emphasises unconscious drives, the tripartite personality (id, ego, superego), psychosexual stages, and defence mechanisms. Humanistic psychology (Maslow, Rogers) focuses on free will, self‑actualisation, and conditions of worth, advocating unconditional positive regard.
心理动力和人本主义流派提供了对立的视角。弗洛伊德的心理动力理论强调无意识驱力、三部分人格（本我、自我、超我）、性心理阶段和防御机制。人本主义心理学（马斯洛、罗杰斯）关注自由意志、自我实现和价值条件，提倡无条件积极关注。
6. Biopsychology: Neurons and the Nervous System | 生物心理学：神经元与神经系统
The nervous system is divided into the central nervous system (CNS: brain and spinal cord) and the peripheral nervous system (PNS: somatic and autonomic). The autonomic nervous system further splits into sympathetic (arousing, fight‑or‑flight) and parasympathetic (rest and digest) branches. The sympathetic branch increases heart rate, dilates pupils, and inhibits digestion, preparing the body for action.
神经系统分为中枢神经系统（CNS：脑和脊髓）和外周神经系统（PNS：躯体神经系统和自主神经系统）。自主神经系统进一步分为交感神经（唤醒，战斗或逃跑）和副交感神经（休息与消化）。交感神经分支会提高心率、扩大瞳孔并抑制消化，让身体为行动做好准备。
Neurons are specialised cells that transmit electrical and chemical signals. The main types are sensory neurons (carry signals from receptors to CNS), relay neurons (connect sensory to motor or other relay), and motor neurons (carry signals from CNS to effectors). The structure includes dendrites, cell body, axon, myelin sheath, and terminal buttons.
神经元是传输电信号和化学信号的特化细胞。主要类型包括感觉神经元（将信号从感受器传至 CNS）、中继神经元（连接感觉神经元与运动神经元或其他中继神经元）和运动神经元（将信号从 CNS 传至效应器）。结构包括树突、细胞体、轴突、髓鞘和末梢扣。
Synaptic transmission involves neurotransmitter release from presynaptic vesicles into the synaptic cleft, where they bind to postsynaptic receptor sites. Excitation (e.g., dopamine) increases the likelihood of a postsynaptic neuron firing; inhibition (e.g., GABA) decreases it. Summation determines whether the net effect triggers an action potential.
突触传递包括神经递质从前突触囊泡释放到突触间隙，并与后突触受体位点结合。兴奋性作用（如多巴胺）增加后神经元放电的可能性；抑制性作用（如 GABA）则降低。总和效应决定了净效果是否触发动作电位。
The endocrine system works alongside the nervous system to regulate bodily functions through hormones. The pituitary gland is the ‘master gland’ controlling other glands. In the fight‑or‑flight response, the hypothalamus signals the adrenal medulla to release adrenaline and noradrenaline, leading to physiological readiness. Chronic stress can over‑activate this system, causing negative health outcomes.
内分泌系统与神经系统协同工作，通过激素调节身体功能。脑垂体是控制其他腺体的“主腺”。在战斗或逃跑反应中，下丘脑指令肾上腺髓质释放肾上腺素和去甲肾上腺素，引发生理准备状态。慢性压力会过度激活该系统，导致负面健康后果。
7. Research Methods: Designs and Sampling | 研究方法：设计与抽样
Experimental methods are the only way to establish cause‑and‑effect relationships. Laboratory experiments have high internal validity but low ecological validity; field experiments occur in natural settings but lack control over extraneous variables; natural experiments exploit naturally occurring independent variables; quasi‑experiments compare existing groups without random allocation. Each design must consider demand characteristics and investigator effects.
实验法是唯一能确立因果关系的方法。实验室实验内部效度高但生态效度低；现场实验在自然场景进行但缺少对外部变量的控制；自然实验利用自然发生的自变量；准实验比较现有组别而不进行随机分配。每种设计都必须考虑需求特征和研究者效应。
Observational techniques can be covert or overt, participant or non‑participant, and use time or event sampling. Structured observations use predefined coding schemes, increasing reliability but potentially missing subtle behaviours. The main limitation is observer bias; using multiple raters and inter‑observer reliability checks helps overcome this.
观察技术可分为隐蔽或公开、参与或非参与，并使用时间取样或事件取样。结构式观察使用预先定义的编码方案，提高了信度但可能遗漏细微行为。主要限制是观察者偏差；使用多名评定者和评分者间信度检查有助于克服此问题。
Self‑report methods include questionnaires (open and closed questions) and interviews (structured, unstructured, semi‑structured). Likert scales and semantic differentials are commonly used rating scales. Self‑report is prone to social desirability bias and acquiescence bias; anonymity and reverse‑worded items can mitigate these.
自我报告方法包括问卷（开放式和封闭式问题）和访谈（结构化、非结构化、半结构化）。李克特量表和语义差异法是常用的评分量表。自我报告容易出现社会赞许性偏差和默许偏差；匿名和反向措辞项目可以减轻这些问题。
Correlational studies measure the strength and direction of a relationship between two co‑variables without manipulation. A positive correlation means both variables increase together; a negative correlation means one increases as the other decreases. Correlation coefficients range between -1 and +1. Crucially, correlation does not imply causation because of the third‑variable problem and direction of effect ambiguity.
相关研究测量两个协变量之间关系的强度和方向，不进行操纵。正相关表示两变量同向变化；负相关表示一增一降。相关系数范围为 -1 至 +1。关键一点是相关不能推论因果，因为存在第三变量问题和效应方向模糊。
Sampling techniques include random (everyone has equal chance), systematic (every nth person), stratified (subgroups proportionately represented), opportunity (convenience), and volunteer (self‑selection). Random sampling is ideal but seldom practical; opportunity sampling is common but may yield unrepresentative samples. Pilot studies refine procedures before main data collection.
抽样技术包括随机抽样（人人机会相等）、系统抽样（每隔 n 人选取）、分层抽样（按比例代表子群）、便利抽样（方便获取）和志愿者抽样（自我选择）。随机抽样理论最佳但难得实施；便利抽样常用但可能产生无代表性的样本。预试研究在正式收集数据前完善程序。
8. Data Handling and Descriptive Statistics | 数据处理与描述统计
Quantitative data are numerical and suitable for statistical analysis; qualitative data are descriptive and rich in detail. Primary data are collected firsthand; secondary data come from existing sources. Each type has strengths and limitations in terms of validity, reliability, and cost.
定量数据是数值型的，适合统计分析；定性数据是描述性的，细节丰富。原始数据由研究者直接收集；二次数据来自已有来源。每种类型在效度、信度和成本方面各有优缺点。
Measures of central tendency—mean, median, mode—summarise the ‘typical’ value. The mean is most sensitive but easily skewed by outliers. Measures of dispersion—range, interquartile range, and standard deviation—describe spread. Standard deviation is more robust than the range for interval/ratio data.
集中趋势度量——平均数、中位数、众数——概括“典型”值。平均数最为灵敏但易受异常值影响。离散度量——全距、四分位距和标准差——描述分散程度。对于间隔/比率数据，标准差比全距更稳健。
Data can be displayed using tables, bar charts, histograms, scattergrams, and normal distribution curves. Bar charts present categorical data, histograms show continuous data, and scattergrams plot co‑variables. A normal distribution is symmetrical and bell‑shaped; skewness and kurtosis describe departures from normality.
数据可用表格、条形图、直方图、散点图和正态分布曲线显示。条形图呈现类别数据，直方图显示连续数据，散点图绘制协变量。正态分布是对称的钟形曲线；偏度和峰度描述偏离正态的程度。
Percentages and ratios simplify comparisons across conditions. Content analysis transforms qualitative material into quantitative data by coding; thematic analysis identifies broader themes. Both require careful operationalisation of coding units to ensure reliability.
百分比和比率简化了不同条件下的比较。内容分析通过编码将定性材料转化为定量数据；主题分析识别更宽泛的主题。两者都需谨慎操作化编码单元以确保信度。
9. Ethical Issues in Research | 研究中的伦理问题
The British Psychological Society (BPS) Code of Ethics requires researchers to obtain informed consent, avoid deception unless justified, protect participants from harm, ensure confidentiality, and offer the right to withdraw. Vulnerable populations—children, the mentally ill, prisoners—require additional safeguards.
英国心理学会（BPS）伦理准则要求研究者获得知情同意、除非合理否则避免欺骗、保护参与者免受伤害、确保保密信息、并提供退出权。弱势群体——儿童、精神病患者、囚犯——需要额外保护措施。
When deception is necessary, a thorough debrief must explain the true purpose and offer the opportunity to withhold data. Retrospective consent or presumptive consent may be used when full prior consent is impossible. Cost‑benefit analyses weigh the value of research findings against potential harm to participants.
当欺骗不可避免时，必须进行全面的事后解释，说明真实目的并提供撤回数据的机会。在无法获得完整事先同意时，可使用回溯同意或推定同意。成本效益分析权衡研究结果的价值与对参与者的潜在伤害。
Dealing with ethical issues in socially sensitive research (Sieber & Stanley) requires special caution. Research on race, gender, or sexuality can fuel stereotypes and prejudice. Researchers must consider the wider implications of their work and avoid ‘psychology is value‑free’ assumptions.
处理社会敏感研究（西伯和斯坦利）中的伦理问题需要格外谨慎。关于种族、性别或性取向的研究可能助长刻板印象和偏见。研究者必须考虑其工作的更广泛影响，避免“心理学无价值取向”的假设。
10. AQA‑Specific Exam Strategy | AQA 特定考试策略
Year 12 AQA Psychology papers test knowledge (AO1), application (AO2), and evaluation (AO3). For each topic, you must be able to describe key theories and studies, apply them to novel scenarios, and critically discuss strengths and limitations. Essay questions typically require P.E.E.L paragraphs (Point, Evidence, Explanation, Link) and balanced evaluation.
AQA Year 12 心理学试卷考查知识（AO1）、应用（AO2）和评价（AO3）。对于每个主题，你必须能够描述关键理论和研究，应用到新情境中，并批判性地讨论优点与局限。论述题通常需要 P.E.E.L 段落结构（观点、证据、解释、联系）和平衡的评价。
Key studies such as Milgram, Asch, Ainsworth, Bowlby, and Rutter repeatedly appear. Memorise the procedures, findings, and conclusions—but also be ready to evaluate methodology, ethics, and real‑world relevance. Comparison of approaches is a common synoptic question; practise linking, for example, the biological and cognitive explanations of OCD.
米尔格拉姆、阿希、安斯沃思、鲍尔比和鲁特等关键研究反复出现。要熟记它们的步骤、发现和结论——同时也要准备好评价其方法、伦理和现实意义。流派比较是常见的综合题；例如，练习将强迫症的生物学解释与认知解释相联系。
Effective revision includes active recall (self‑testing), spaced repetition, and interleaving topics. Use flashcards for definitions and researchers’ names, mind maps for essay plans, and practice papers under timed conditions. Mark schemes reward precise use of psychological terminology; never use lay language when a technical term exists.
高效复习包括主动回忆（自测）、间隔重复和交替学习不同主题。使用抽认卡记忆定义和研究者姓名，用思维导图规划论文，以及限时练习试卷。评分方案奖励准确使用心理学专业术语；存在专门术语时绝不使用日常用语。
