1. Memory Models and Forgetting 记忆模型与遗忘机制

The Multi-Store Model (Atkinson & Shiffrin, 1968) posits three distinct memory stores: sensory register, short-term memory (STM), and long-term memory (LTM). 多储存模型提出三个独立的记忆存储系统：感觉登记、短时记忆和长时记忆。Information moves from sensory register to STM through attention, and from STM to LTM through elaborative rehearsal. 信息通过注意力从感觉登记进入短时记忆，再经过精细复述进入长时记忆。 AO1 Key Points 知识要点： - Sensory register: modality-specific, duration 0.25-0.5 seconds, unlimited capacity. 感觉登记具有通道特异性，持续0.25至0.5秒，容量无限。 - STM: acoustic coding, 7±2 chunks (Miller, 1956), duration 18-30 seconds without rehearsal. 短时记忆以听觉编码为主，容量7±2个组块，不经复述持续18至30秒。 - LTM: semantic coding, potentially unlimited capacity and duration. 长时记忆以语义编码为主，容量和持续时间可能无限。 AO3 Evaluation 评估要点： A major strength is supporting evidence from the serial position effect (Glanzer & Cunitz, 1966) where primacy and recency effects map onto LTM and STM respectively. 系列位置效应的实验证据是该模型的重要支持，首因效应和近因效应分别对应长时记忆和短时记忆。However, the model is overly simplistic — it assumes STM and LTM are unitary stores, which is challenged by the Working Memory Model (Baddeley & Hitch, 1974) and cases like KF who had impaired verbal STM but intact visual STM. 然而该模型过于简化，它将短时记忆和长时记忆视为单一存储系统，这一假设受到工作记忆模型和KF个案研究的挑战，KF的言语短时记忆受损但视觉短时记忆完好。 The Working Memory Model replaces the passive STM with an active multi-component system: central executive, phonological loop, visuospatial sketchpad, and episodic buffer (added later). 工作记忆模型用主动的多成分系统取代了被动的短时记忆概念，包含中央执行器、语音回路、视空间画板和情境缓冲器。The model explains how we can perform two tasks simultaneously if they use different slave systems — for example, verbal reasoning while tracking a moving object. 该模型解释了为何我们在使用不同子系统时可以同时执行两项任务，例如一边进行言语推理一边追踪移动物体。 Forgetting theories 遗忘理论： Interference theory suggests forgetting occurs because similar memories disrupt each other. Retroactive interference: new learning disrupts old memories. Proactive interference: old learning disrupts new memories. 干扰理论认为遗忘因相似记忆相互干扰而产生。倒摄抑制指新学习的材料干扰旧记忆，前摄抑制指旧知识干扰新学习。McGeoch and McDonald (1931) demonstrated that similarity between material increases interference — participants recalling a list of adjectives did worse when the second list was also adjectives rather than nonsense syllables. McGeoch和McDonald的经典实验证明材料越相似，干扰越强——当两组学习材料都是形容词时，回忆成绩最差。 Retrieval failure theory, based on the Encoding Specificity Principle (Tulving, 1983), argues that forgetting happens when the cues present at recall differ from those present at encoding. 提取失败理论基于编码特异性原则，认为当回忆时的线索与编码时的线索不匹配时，遗忘就会发生。Context-dependent forgetting: Godden and Baddeley (1975) found that deep-sea divers recalled 40% more words when the learning and recall environments matched. 情境依赖遗忘：Godden和Baddeley的水下实验表明，当学习和回忆环境一致时，潜水员的单词回忆量高出40%。State-dependent forgetting: Carter and Cassaday (1998) found that anti-histamine drugs created internal states where recall was better when learning and testing states matched. 状态依赖遗忘：抗组胺药物实验证明，当学习和测试时的生理状态一致时，回忆表现更好。

2. Social Influence: Conformity, Obedience, and Resistance 从众、服从与抵抗

Social influence examines how individuals change their behavior to meet the demands of a social environment. 社会影响研究个体如何改变行为以符合社会环境的要求。Three types of conformity (Kelman, 1958): compliance (public change, private disagreement), identification (temporary change to fit a group role), and internalisation (genuine acceptance of group norms). 三种从众类型：顺从（公开改变，私下不同意）、认同（暂时改变以适应群体角色）和内化（真正接受群体规范）。 Asch's Conformity Research 阿希从众实验（1951, 1955）： Asch asked participants to judge line lengths in a group of confederates who unanimously gave wrong answers on 12 out of 18 critical trials. 阿希让被试在由假被试组成的群体中判断线段长度，假被试在18个关键试次中的12个上一致给出错误答案。The naive participant conformed on approximately 37% of critical trials. 约37%的关键试次中真被试选择了从众。75% conformed at least once. 75%的被试至少从众过一次。 Situational variables affecting conformity 影响从众的情境变量： Asch varied group size and found conformity increased with group size up to 3 confederates, then plateaued. 阿希变换群体规模，发现从众率随假被试数量增加而上升，但达到3人后趋于稳定。The presence of a dissenter reduced conformity to just 5.5%, demonstrating the power of social support. 当出现一个持异议者时，从众率骤降至5.5%，显示了社会支持的力量。Task difficulty: when the comparison lines were made more similar, conformity increased significantly. 任务难度：当比较线段更相似时，从众率显著上升。 Milgram's Obedience Studies 米尔格拉姆服从实验（1963）： Milgram recruited 40 male participants through a newspaper advertisement, ostensibly for a study on memory and learning. 米尔格拉姆通过报纸广告招募了40名男性被试，表面上研究记忆与学习。Participants were instructed to administer increasingly severe electric shocks to a "learner" (confederate) for each wrong answer, up to 450V. 被试被要求对"学习者"（假被试）的每次错误回答施加逐渐增强的电击，最高可达450伏特。65% of participants administered the full 450V, and 100% went to 300V. 65%的被试施加了全程450伏特电击，100%到达了300伏特标记。 Situational factors explaining obedience 解释服从的情境因素： Proximity: when the teacher and learner were in the same room, obedience dropped to 40%; touch proximity dropped it to 30%. 接近性：当教师与学习者在同一房间时，服从率降至40%；需要身体接触时降至30%。Location: when the study moved from Yale University to a run-down office building, obedience fell to 47.5%. 地点：实验从耶鲁大学搬到破旧的办公楼后，服从率降至47.5%。Uniform: the experimenter wore a grey lab coat symbolising legitimate authority — when replaced by an ordinary member of the public in plain clothes, obedience was just 20%. 制服：主试穿着象征合法权威的灰色实验服，当由穿便服的普通人代替时，服从率仅为20%。 Agentic state theory 代理状态理论（Milgram, 1974）： Milgram proposed that people shift between an autonomous state (acting on personal conscience) and an agentic state (acting as an agent for an authority figure). 米尔格拉姆提出人们在自主状态和代理状态之间转换，后者将自己视为权威人物的代理人。Moral strain occurs when people want to disobey but feel they cannot, producing anxiety. 道德压力发生在人们想违抗但感觉无法违抗时，产生焦虑感。This is supported by participants' observable distress: trembling, sweating, nervous laughter, and three participants having full seizures. 被试可观察的痛苦表现支持这一理论：颤抖、出汗、紧张的笑，三名被试甚至出现全身性癫痫发作。 Resistance to social influence 抵抗社会影响： Locus of Control (Rotter, 1966): individuals with an internal locus of control — who believe events result from their own actions — are more likely to resist conformity and obedience pressures. 控制点理论：具有内控倾向的个体更可能抵抗从众和服从压力。Social support breaks the unanimous majority, as shown by Asch's dissenter condition. 社会支持打破一致多数，阿希实验中持异议者条件证明了这一点。 Minority influence and social change 少数派影响与社会变革： Moscovici et al. (1969) demonstrated that a consistent minority can influence the majority. 莫斯科维奇实验表明一个坚定的少数派可以影响多数派。In the blue-green slide study, when two confederates consistently called blue slides "green," 8.42% of majority responses shifted. 在蓝绿幻灯片研究中，当两名假被试一致将蓝色幻灯片称为"绿色"时，约8.42%的多数派回答发生转变。Consistency, commitment, and flexibility are key to minority influence. 一致性、承诺和灵活性是少数派影响的三个关键因素。This explains how social change occurs — suffragettes, civil rights movements, and environmental activism all began as minority positions that gradually converted the majority through consistent messaging over time. 这解释了社会变革的发生机制——妇女参政运动、民权运动和环境运动都始于少数派立场，通过长期的坚定传播逐渐转化了多数派。

3. Attachment: Development, Types, and Cultural Variations 依恋关系的发展、类型与文化差异

Attachment is a deep and enduring emotional bond connecting one person to another across time and space. 依恋是一种跨越时空的深刻情感联结。Bowlby (1969) proposed that attachment has an evolutionary basis — infants are born with innate social releasers (crying, smiling, clinging, gazing) that trigger caregiving responses from adults. 鲍尔比提出依恋具有进化基础，婴儿天生具备社交释放器（哭、笑、依附、注视），这些行为触发成人的照料反应。 Stages of attachment development 依恋发展阶段（Schaffer & Emerson, 1964）： Stage 1 (0-2 months): Pre-attachment — infants respond similarly to all caregivers. 前依恋阶段：婴儿对所有照护者反应相似。Stage 2 (2-7 months): Indiscriminate attachment — infants show preference for familiar people but accept comfort from anyone. 无差别依恋阶段：婴儿偏好熟悉的人但仍接受任何人的安抚。Stage 3 (7-24 months): Specific attachment — infants show separation anxiety and stranger anxiety, forming a primary attachment to one figure (usually the mother in 65% of cases). 特定依恋阶段：婴儿表现出分离焦虑和陌生人焦虑，形成对主要照护者的依恋（65%案例中为母亲）。Stage 4 (24+ months): Multiple attachments — infants form attachments to additional figures (father, grandparents, siblings). 多重依恋阶段：婴儿形成对多人的依恋关系。 Role of the father 父亲的角色： Schaffer and Emerson found that by 18 months, 75% of infants had formed an attachment to their father. Schaffer和Emerson发现18个月时75%的婴儿已与父亲形成依恋。Grossmann et al. (2002) conducted a longitudinal study and found that fathers tend to adopt a playmate role, with the quality of father-child play at age 2 predicting attachment quality in adolescence, while the quality of maternal caregiving at age 2 was more associated with maternal attachment. Grossmann的纵向研究表明父亲倾向于扮演玩伴角色，2岁时父子游戏质量预测了青春期的依恋质量，而母亲的照料质量更多关联母子依恋。 Animal studies 动物研究： Lorenz (1935) demonstrated imprinting in geese — goslings attach to the first moving object they see after hatching. 洛伦兹的印刻实验表明幼鹅会对孵化后看到的第一个移动物体形成依恋。Harlow (1958) reared infant rhesus monkeys with two surrogate mothers: one wire mother providing food and one cloth mother providing comfort. 哈洛用两个替代母亲抚养幼年恒河猴：一个铁丝母亲提供食物，一个绒布母亲提供安抚。Monkeys spent 17-18 hours per day with the cloth mother and only went to the wire mother to feed, demonstrating that contact comfort is more important than food in forming attachment. 幼猴每天与绒布母亲相处17至18小时，仅进食时接近铁丝母亲，证明接触安慰比食物在依恋形成中更为重要。Long-term consequences: maternally deprived monkeys grew up socially and sexually abnormal, unable to parent their own offspring. 长期后果：母爱剥夺的猴子长大后社交和性行为异常，无法正常抚育后代。 Strange Situation and attachment types 陌生情境实验与依恋类型（Ainsworth et al., 1978）： The Strange Situation is a controlled observation with eight episodes designed to assess the quality of attachment between infant and caregiver. 陌生情境是一种包含8个场景的控制观察实验，用于评估婴儿与照护者之间的依恋质量。Three main attachment types were identified: Secure (Type B, 66%) — infant explores freely, shows distress at separation, seeks comfort at reunion. 安全型：婴儿自由探索，分离时痛苦，重聚时寻求安抚。Insecure-Avoidant (Type A, 22%) — infant explores without checking on caregiver, shows little distress at separation, ignores caregiver at reunion. 不安全回避型：婴儿探索时不关注照护者，分离时痛苦少，重聚时回避。Insecure-Resistant (Type C, 12%) — infant clings to caregiver, extremely distressed at separation, resists comfort at reunion, showing ambivalence. 不安全抗拒型：婴儿粘着照护者，分离时极度痛苦，重聚时既寻求又抗拒安抚，表现出矛盾行为。 Cultural variations in attachment 依恋的文化差异： Van IJzendoorn and Kroonenberg (1988) conducted a meta-analysis of 32 Strange Situation studies across 8 countries, involving 1,990 infants. Van IJzendoorn和Kroonenberg对8个国家32项陌生情境研究进行了元分析，涉及1990名婴儿。Secure attachment was the most common type in all cultures (ranging from 50% in China to 75% in Great Britain). 所有文化中安全型依恋均最常见（中国50%至英国75%）。Intra-cultural variation (variation within a single culture) was 1.5 times greater than inter-cultural variation. 文化内部差异是文化间差异的1.5倍，说明养育方式的影响大于文化规范的影响。Germany showed the highest rate of avoidant attachment (35%), explained by the German cultural value of early independence training. 德国回避型依恋比例最高（35%），这可能与德国文化重视早期独立性训练有关。Japan and Israel showed higher rates of resistant attachment (27% and 29% respectively), possibly because Japanese infants are rarely separated from mothers and Israeli kibbutzim practice communal sleeping. 日本和以色列抗拒型依恋比例较高（分别为27%和29%），可能与日本婴儿很少与母亲分离以及以色列基布兹的集体睡眠实践有关。 Maternal deprivation hypothesis 母爱剥夺假说（Bowlby, 1951, 1953）： Bowlby argued that continuous, warm, intimate care from a mother figure is essential for mental health, and that prolonged separation causes irreversible damage. 鲍尔比认为来自母亲形象的持续温暖亲密照料对心理健康至关重要，长期分离会造成不可逆的伤害。Critical period: the first 2.5 years of life are critical for attachment formation. 关键期：出生后头两年半是依恋形成的关键时期。His 44 Juvenile Thieves Study (1944) found that 14 out of 44 thieves were classified as affectionless psychopaths, and 12 of those 14 had experienced prolonged maternal separation. 他的44少年小偷研究发现14人被归类为冷漠型精神病态者，其中12人经历过长期母婴分离。However, this is correlational data and cannot establish causation — poverty, family conflict, or institutionalisation may be confounding variables. 然而这是相关数据，不能建立因果——贫困、家庭冲突或收容经历可能是混淆变量。

4. Psychopathology: Definitions and Approaches 精神病理学的定义与治疗取向

Psychopathology examines the definitions of abnormality and the major approaches to explaining and treating mental disorders. 精神病理学研究心理异常的定义以及解释和治疗心理障碍的主要方法。 Four definitions of abnormality 四种心理异常的定义：

广告 / Sponsored

Statistical infrequency: behavior is abnormal if it is statistically rare, measured on a normal distribution curve. 统计罕见性：如果行为位于正态分布曲线的两端且统计上罕见，即被视为异常。This is objective and value-free but fails to distinguish between desirable and undesirable rare behaviors (high IQ is statistically rare but not a disorder). 该方法客观且无价值判断，但无法区分期望和不期望的罕见行为（高智商统计上罕见但非障碍）。Deviation from social norms: behavior violates implicit or explicit rules of society. 社会规范偏离：行为违反社会隐含或明示的规则。This accounts for cultural context but norms change over time — homosexuality was classified as a mental disorder in the DSM until 1973. 它考虑了文化背景，但规范随时间变化——同性恋在1973年之前被DSM列为心理障碍。Failure to function adequately (Rosenhan & Seligman, 1989): a person is abnormal when they can no longer cope with everyday life. Seven criteria include personal distress, maladaptive behavior, unpredictability, irrationality, observer discomfort, violation of moral standards, and unconventionality. 功能失常（七项标准）：当个体无法应对日常生活时即为异常，包含个人痛苦、适应不良行为、不可预测性、非理性、观察者不适、违反道德标准和非常规性。Deviation from ideal mental health (Jahoda, 1958): abnormality is the absence of six criteria for ideal mental health — positive self-attitude, self-actualisation, resistance to stress, autonomy, accurate perception of reality, and mastery of the environment. 理想心理健康偏离：异常是缺乏六项理想心理健康标准，包括积极自我态度、自我实现、抗压能力、自主性、准确感知现实和环境掌控能力。 Phobias: behavioral approach 恐惧症的行为主义解释（Two-Process Model, Mowrer, 1947）： Phobias are acquired through classical conditioning and maintained through operant conditioning. 恐惧症通过经典条件作用习得，通过操作条件作用维持。Watson and Rayner (1920) demonstrated classical conditioning with Little Albert — a 9-month-old infant conditioned to fear a white rat by pairing it with a loud noise, a fear that generalised to other white furry objects. 华生和雷纳的小阿尔伯特实验经典地演示了恐惧的条件化习得——通过将白鼠与巨响配对，9个月大的婴儿形成了对白鼠的恐惧，并泛化到其他白色毛绒物体。Phobias are maintained by negative reinforcement: avoidance of the phobic stimulus reduces anxiety (removing an unpleasant state), reinforcing the avoidance behavior. 恐惧症通过负强化维持：回避恐惧刺激减轻了焦虑（移除不愉快状态），从而强化了回避行为。 Systematic desensitisation 系统脱敏法（Wolpe, 1958）： Based on reciprocal inhibition — it is impossible to be relaxed and anxious at the same time. 基于交互抑制原理——人无法同时处于放松和焦虑状态。The client constructs an anxiety hierarchy (from least to most feared situations), learns deep relaxation techniques, and works through the hierarchy while maintaining relaxation. 来访者构建焦虑等级（从最轻到最恐惧的情境），学习深度放松技术，并在保持放松状态下按等级逐步暴露。Gilroy et al. (2003) followed up with 42 spider phobia patients after three sessions of systematic desensitisation and found them significantly less fearful than a control group at both 3 months and 33 months. Gilroy对42名蜘蛛恐惧症患者进行了三次系统脱敏后的跟踪研究，发现3个月和33个月后他们的恐惧程度显著低于对照组。 Flooding 满灌疗法： The client is exposed to the most feared stimulus immediately, without a gradual build-up. 来访者立即暴露于最恐惧的刺激中，没有渐进过程。Sessions typically last 2-3 hours, during which the client's fear peaks and then subsides as they learn the feared catastrophe does not occur — extinction occurs. 疗程通常持续2至3小时，期间来访者的恐惧达到峰值后消退，因为他们意识到灾难性后果并未发生——消退发生。Flooding is quicker and more cost-effective than systematic desensitisation but has higher dropout rates due to the intense distress involved. 满灌疗法比系统脱敏更快、更具成本效益，但因痛苦程度高导致脱落率较高。 Depression: cognitive approach 抑郁症的认知解释： Beck's Cognitive Triad (1967) proposes that depression arises from negative schemas producing three types of automatic negative thoughts: negative views of the self ("I am worthless"), the world ("Everyone is against me"), and the future ("Things will never get better"). 贝克的认知三合一理论提出抑郁症源于认知图式产生的三类自动负性思维：对自我的负面看法（"我一无是处"）、对世界的负面看法（"人人都针对我"）和对未来的负面看法（"事情永远不会好转"）。Negative schemas develop from childhood experiences — parental rejection, criticism, or loss — and are activated by stressful life events. 负面图式源于童年经历——父母的拒绝、批评或丧失——并在应激性生活事件中被激活。 Cognitive Behavioral Therapy 认知行为疗法（CBT）： CBT combines cognitive techniques (identifying and challenging irrational thoughts) with behavioral techniques (behavioral activation, scheduling pleasant activities). 认知行为疗法结合认知技术（识别和挑战非理性思维）与行为技术（行为激活、安排愉快活动）。Ellis's REBT model (ABCDE framework): Activating event triggers irrational Beliefs, producing emotional and behavioral Consequences; the therapist Disputes irrational beliefs, leading to Effective new beliefs. 埃利斯的理性情绪行为疗法ABCDE框架：激活事件触发非理性信念，产生情绪和行为后果；治疗师质疑非理性信念，导向有效的新信念。March et al. (2007) compared CBT, antidepressant medication, and a combination in 327 adolescents with depression and found all three equally effective at 12 weeks (81% improvement rate), demonstrating CBT's effectiveness. March对327名抑郁青少年的研究比较了CBT、抗抑郁药物和联合治疗，发现12周时三种方法同样有效（81%改善率），证明了CBT的疗效。 OCD: biological approach 强迫症的生物学解释： Genetic explanation: Nestadt et al. (2000) found a concordance rate of 68% for MZ twins versus 31% for DZ twins, indicating a significant genetic component. 基因解释：Nestadt的同卵双生子一致率为68%，异卵双生子为31%，表明存在显著的遗传因素。Neural explanation: PET scans show increased activity in the orbitofrontal cortex (OFC), which is involved in decision-making and the "worry circuit". 神经解释：PET扫描显示眶额皮层活动增强，该区域参与决策和"担忧回路"。The caudate nucleus, which normally suppresses signals from the OFC, appears damaged in OCD patients, so worry signals are not suppressed. 尾状核通常抑制来自OFC的信号，但在OCD患者中似乎受损，导致担忧信号无法被抑制。SSRIs increase serotonin levels, which may normalize activity in these brain circuits. 选择性5-羟色胺再摄取抑制剂提高5-羟色胺水平，可能使这些脑回路的活动正常化。

5. Research Methods: Design, Ethics, and Data Analysis 研究方法：实验设计、伦理与数据分析

Research methods form the backbone of all AQA Psychology exam papers. 研究方法是AQA心理学试卷的核心基础。You must be able to design studies, evaluate methodologies, and interpret statistical findings. 你必须能够设计研究、评估方法学并解读统计结果。 Experimental designs 实验设计： Independent groups: different participants in each condition. Strengths: no order effects, less demand characteristics. Limitations: participant variables may confound results, requires more participants. 独立组设计：不同被试参与不同条件。优点：无顺序效应，需求特征较少。局限：被试变量可能混淆结果，需要更多被试。Repeated measures: same participants in all conditions. Strengths: controls participant variables, fewer participants needed. Limitations: order effects (fatigue, practice), demand characteristics as participants see all conditions. 重复测量设计：相同被试参与所有条件。优点：控制被试变量，需要较少被试。局限：顺序效应（疲劳、练习效应），需求特征。Matched pairs: different but matched participants in each condition. Strengths: controls order effects and participant variables. Limitations: time-consuming and difficult to match on all relevant variables. 配对组设计：不同但匹配的被试参与各条件。优点：控制顺序效应和被试变量。局限：耗时且难以在所有相关变量上匹配。 Types of experiments 实验类型： Laboratory experiments: high internal validity (controlled IV and DV), high replicability, but low ecological validity and demand characteristics. 实验室实验：高内部效度（控制自变量和因变量），高可重复性，但生态效度低，存在需求特征。Field experiments: IV manipulated in natural setting, higher ecological validity, reduced demand characteristics (participants often unaware), but less control of extraneous variables and ethical issues with lack of informed consent. 现场实验：在自然情境中操控自变量，更高的生态效度，减少需求特征（被试通常不知情），但对额外变量控制较少，存在知情同意缺失的伦理问题。Natural experiments: IV naturally occurring (e.g., before/after a disaster), cannot establish causation, but allows study of variables that cannot be ethically manipulated. 自然实验：自变量自然发生（如灾难前后对比），无法建立因果，但允许研究无法伦理操控的变量。Quasi-experiments: IV based on existing differences (e.g., gender, age), no random allocation, but useful for studying pre-existing group differences. 准实验：自变量基于既有差异（如性别、年龄），无随机分配，但可用于研究既有群体差异。 Observational techniques 观察技术： Naturalistic observation: observing behavior in its natural environment, high ecological validity but low control. 自然观察：在自然环境中观察行为，生态效度高但控制力低。Controlled observation: observing behavior in a structured setting (e.g., Ainsworth's Strange Situation), higher control but may lack ecological validity. 控制观察：在结构化环境中观察行为（如陌生情境实验），控制力强但可能缺乏生态效度。Covert observation: participants unaware of being observed, reduces demand characteristics but raises ethical issues. 隐蔽观察：被试不知道被观察，减少需求特征但引发伦理问题。Participant observation: researcher joins the group being studied, provides unique insights but risks objectivity. 参与观察：研究者加入被研究群体，提供独特洞察但可能失去客观性。 Self-report methods 自陈方法： Questionnaires: use open questions (qualitative data, rich detail) and closed questions (quantitative data, easy to analyse). 问卷：使用开放式问题（质性数据，丰富细节）和封闭式问题（量化数据，易于分析）。Avoid leading questions, double-barrelled questions, and ambiguity. 避免诱导性问题、双重问题和歧义。Interviews: structured (fixed questions, reliable but limited), semi-structured (guide questions with flexibility), unstructured (open conversation, rich data but hard to replicate). 访谈：结构化（固定问题，信度高但受限）、半结构化（有引导问题的灵活性）、非结构化（开放式对话，丰富数据但难以复制）。 Correlations 相关研究： Correlation coefficient: ranges from -1.0 (perfect negative) to +1.0 (perfect positive), with 0 indicating no relationship. 相关系数：范围从负1.0（完美负相关）到正1.0（完美正相关），0表示无关系。Crucially, correlation does not imply causation — a third variable may explain the relationship. 关键点：相关不等于因果——存在第三变量的可能。Strengths: useful when variables cannot be experimentally manipulated for ethical or practical reasons, provides starting point for experimental research. 优点：当变量因伦理或实践原因无法实验操控时有用，提供实验研究的起点。Limitations: cannot establish cause and effect, susceptible to intervening variables. 局限：无法建立因果关系，易受中间变量影响。 Content and thematic analysis 内容分析与主题分析： Content analysis: systematically coding qualitative data into quantitative categories. Steps include sampling, coding units, establishing categories, and calculating frequencies. 内容分析：系统地将质性数据编码为量化类别，步骤包括抽样、编码单元、建立类别和计算频率。High ecological validity but may suffer from subjective interpretation by the researcher. 高生态效度但可能受到研究者主观解读的影响。Thematic analysis: identifying themes and patterns in qualitative data through familiarisation, coding, searching for themes, reviewing themes, defining and naming themes, and writing up. 主题分析：通过熟悉数据、编码、搜索主题、审查主题、定义命名主题和撰写报告六个步骤识别质性数据中的主题和模式。Braun and Clarke's (2006) six-step model ensures a rigorous process. Braun和Clarke的六步模型确保过程的严谨性。 Inferential statistics 推断统计： Sign test: a non-parametric test for repeated measures or matched pairs designs with nominal data. 符号检验：适用于重复测量或配对组设计的名义数据的非参数检验。Calculate the sign of the difference for each participant, count the less frequent sign (S), and compare to the critical value from the sign test table. 计算每个被试差异的符号，计数较少出现的符号，与符号检验表中的临界值比较。If S is less than or equal to the critical value, the result is significant and the null hypothesis is rejected. 如果S小于或等于临界值，结果显著，拒绝零假设。Type I error: false positive — rejecting a true null hypothesis (more likely with lenient p-value such as 0.10). 第一类错误：假阳性——拒绝真实的零假设（宽松的p值如0.10更易发生）。Type II error: false negative — accepting a false null hypothesis (more likely with strict p-value such as 0.01). 第二类错误：假阴性——接受错误的零假设（严格的p值如0.01更易发生）。 Ethical issues 伦理问题： BPS Code of Ethics (2021) outlines four principles: Respect (informed consent, right to withdraw, confidentiality), Competence (researchers must be qualified), Responsibility (protection from harm, debriefing), and Integrity (honest reporting, no deception unless justified). 英国心理学会伦理准则包含四项原则：尊重（知情同意、退出权、保密）、胜任力（研究者必须具备资质）、责任（保护免受伤害、事后说明）和诚信（诚实报告、除非必要不欺骗）。Deception should only be used when essential, with a thorough debrief afterward. 欺骗仅在必要时使用，并需在事后进行充分的解释说明。

AQA Psychology Study Tips 备考策略总结

AO1 = 6 marks
Define, describe, outline AO2 = 4 marks
Apply to novel scenarios AO3 = 6 marks
Evaluate, discuss, compare Exam Command Words 考试指令词解码 Outline: give a brief account 简要描述 Describe: provide detailed account 详细描述 Evaluate: discuss strengths and limitations 评估优缺点 Discuss: present both sides with conclusion 讨论正反两面并给出结论 Compare: identify similarities and differences 比较异同 AQA A-Level Psychology rewards precision — every 16-mark essay should follow a clear structure. AQA A-Level心理学考试奖励精准表达——每道16分论文题都应遵循清晰结构。Begin with a concise AO1 knowledge paragraph (describe the theory, model, or study). 以简洁的AO1知识段开头（描述理论、模型或研究）。Follow with four well-developed AO3 evaluation paragraphs, each making a clear point, providing supporting evidence, explaining why the point matters, and linking back to the question. 接着四个充分的AO3评估段，每段提出明确观点、提供支持证据、解释该观点为何重要，并回扣题目。Use the PEEL structure: Point, Evidence, Explanation, Link. 使用PEEL结构：观点、证据、解释、回扣。Time management is essential — Paper 1 (Social Influence, Memory, Attachment, Psychopathology) requires 96 marks in 120 minutes, giving roughly 75 seconds per mark. 时间管理至关重要——试卷一（社会影响、记忆、依恋、精神病理学）96分/120分钟，约每分75秒。 Research methods questions appear across all three papers, contributing 25-30% of total marks — invest significant revision time in experimental design, data analysis, and ethical considerations. 研究方法题目跨越全部三张试卷，占总分的25-30%——在实验设计、数据分析和伦理考量方面值得投入大量复习时间。Memorise researcher names and dates — the specification rewards specific references. 记住研究者姓名和年份——评分标准奖励具体的文献引用。Finally, practice with past papers under timed conditions; the gap between knowing content and performing under pressure is a skill in itself. 最后，在限时条件下用历年真题练习；将知识转化为限时压力下的表现本身就是一个需要训练的独立技能。
