本指南全面总结了 Year 10 CIE IGCSE 心理学（0977）的核心内容，涵盖研究方法与六大主题领域。掌握这些基本概念将为你考试成功奠定坚实基础。
1. Introduction to Research Methods | 研究方法导论
In psychological research, an aim is a general statement of what the researcher intends to investigate, while a hypothesis is a precise, testable prediction about the relationship between variables. For example, a hypothesis might state that ‘participants who drink 200 mg of caffeine will recall more words from a list than those who drink none.’
在心理学研究中，研究目的（aim）是研究者打算探究什么的总体陈述，而假设（hypothesis）是关于变量之间关系的精确、可检验的预测。例如，一个假设可能是“摄入200毫克咖啡因的被试比未摄入者能回忆出更多单词”。
The independent variable (IV) is the factor manipulated by the researcher, and the dependent variable (DV) is the factor measured. In the caffeine study, the IV is the amount of caffeine, and the DV is the number of words recalled. Extraneous variables (e.g., time of day, noise) must be controlled so they do not become confounding variables that ruin the experiment’s validity.
自变量（IV）是研究者操纵的因素，因变量（DV）是被测量的因素。在咖啡因研究中，IV 是咖啡因的量，DV 是回忆出的单词数量。额外变量（如一天中的时段、噪音）必须加以控制，以免成为混淆变量而破坏实验的效度。
There are three main experimental designs. Independent groups design uses different participants in each condition, which avoids order effects but can be affected by participant variables. Repeated measures design uses the same participants in all conditions, controlling participant variables but risking order effects like practice or fatigue. Matched pairs design matches participants on key characteristics, reducing participant variables while avoiding order effects, but it is time-consuming.
主要有三种实验设计。独立组设计在每种条件下使用不同的被试，避免了顺序效应，但可能受被试变量影响。重复测量设计在所有条件下使用相同被试，控制了被试变量，但存在练习或疲劳等顺序效应的风险。配对组设计根据关键特征匹配被试，既减少了被试变量又避免了顺序效应，但耗时较长。
Sampling methods determine who takes part. Random sampling gives everyone an equal chance, reducing bias but often impractical. Opportunity sampling selects whoever is available, quick but unrepresentative. Volunteer sampling relies on people offering to participate, which can yield motivated participants but may attract a certain personality type.
抽样方法决定谁参与研究。随机抽样让每个人都有均等机会，减少偏差但常不现实。机会抽样选择最容易接触到的人，快速但有失代表性。志愿者抽样依赖于人们主动参与，可能获得动机强的被试，但容易吸引某类性格的人。
Ethical guidelines are crucial. Researchers must obtain informed consent, avoid deception unless justified, protect participants from harm, ensure confidentiality, and give the right to withdraw. Studies with human participants often need approval from an ethics committee.
伦理准则至关重要。研究者必须取得知情同意，避免欺骗（除非有充分理由），保护被试免受伤害，确保机密性，并给予退出权。涉及人类被试的研究通常需要伦理委员会的批准。
Data can be quantitative (numerical) or qualitative (descriptive). Quantitative data is easier to analyse statistically; qualitative data provides rich detail. Measures of central tendency include the mean (average), median (middle value), and mode (most frequent). The mean is sensitive to outliers, whereas the median is not.
数据可以是定量的（数值型）或定性的（描述型）。定量数据更易统计分析；定性数据提供丰富细节。集中趋势的度量包括均值（平均数）、中位数（中间值）和众数（出现最频繁的值）。均值对异常值敏感，中位数则不然。
2. Memory | 记忆
The multi-store model (Atkinson & Shiffrin, 1968) describes memory as three separate stores. Sensory memory has a large capacity but very brief duration (under half a second for visual information). Information paid attention to passes into short-term memory (STM), which has a capacity of about 7 ± 2 chunks and a duration of around 18–30 seconds without rehearsal. Through elaborative rehearsal, information moves into long-term memory (LTM), which has potentially unlimited capacity and duration.
多存储模型（Atkinson & Shiffrin, 1968）将记忆描述为三个独立的存储库。感觉记忆容量大但持续时间极短（视觉信息不到半秒）。被注意到的信息进入短时记忆（STM），其容量约为7±2个组块，不进行复述时持续时间约18–30秒。通过精细复述，信息进入长时记忆（LTM），其容量和持续时间几乎是无限的。
The working memory model (Baddeley & Hitch, 1974) replaced the idea of a unitary STM. It consists of the central executive (supervisory system with limited capacity), the phonological loop (deals with auditory information; subdivided into phonological store and articulatory control process), the visuospatial sketchpad (processes visual and spatial information), and the episodic buffer (temporary store integrating information from other components and LTM).
工作记忆模型（Baddeley & Hitch, 1974）取代了单一短时记忆的概念。它包含中央执行系统（容量有限的监督系统）、语音回路（处理听觉信息；分为语音存储和发音控制过程）、视空间模板（处理视觉和空间信息），以及情景缓冲区（整合其他成分和LTM信息的临时存储）。
Key studies support these models. In Peterson & Peterson (1959), participants recalled trigrams after counting backwards, showing STM duration decay without rehearsal. Baddeley (1966) found that STM relies on acoustic coding (more errors with acoustically similar words) while LTM relies on semantic coding (errors with semantically similar words). Murdock (1962) demonstrated the serial position effect: words at the beginning (primacy) and end (recency) of a list are recalled better, with primacy linked to LTM and recency to STM.
关键研究支持这些模型。在 Peterson & Peterson（1959）的实验中，被试在三字母组后倒着数数，显示了无复述时 STM 的持续时间会衰退。Baddeley（1966）发现 STM 依赖声学编码（声音相似的词错误更多），而 LTM 依赖语义编码（语义相似的词错误更多）。Murdock（1962）证明了序列位置效应：列表开头（首因效应）和结尾（近因效应）的单词回忆更好，首因效应与 LTM 相关，近因效应与 STM 相关。
Forgetting can occur through interference. Proactive interference is when old memories disrupt new learning; retroactive interference is when new memories disrupt old recall. Context-dependent forgetting occurs when the retrieval environment differs from the encoding environment, as shown by Godden & Baddeley (1975) with divers recalling words better in the same environment.
遗忘可由干扰引起。前摄干扰是旧记忆干扰新学习；倒摄干扰是新记忆干扰旧回忆。情境依赖性遗忘发生在提取环境与编码环境不同时，例如 Godden & Baddeley（1975）发现潜水员在相同环境下回忆单词效果更好。
In eyewitness testimony, Loftus & Palmer (1974) showed that leading questions (using ‘smashed’ vs ‘hit’) distort memory of an event. Post-event information can create false memories. The cognitive interview technique (Fisher & Geiselman, 1992) improves recall by reinstating context, reporting everything, recalling in different orders, and adopting different perspectives.
在目击者证词中，Loftus & Palmer（1974）表明引导性问题（如用“撞碎”与“撞到”）会扭曲对事件的记忆。事后信息会形成虚假记忆。认知访谈技术（Fisher & Geiselman, 1992）通过复原情境、全面报告、变换顺序回忆和转换视角来提高回忆质量。
3. Perception | 感知
Sensation is the detection of stimuli by sense organs; perception is the brain’s interpretation of those sensations. Visual perception relies on monocular depth cues (available with one eye) such as relative size, linear perspective, texture gradient, and height in plane. Binocular cues require two eyes: retinal disparity (the difference between the images on each retina) and convergence (the eyes turning inward for near objects).
感觉是感觉器官对刺激的探测；知觉是大脑对这些感觉的解读。视知觉依赖单眼深度线索（单眼即可获得），如相对大小、线条透视、纹理梯度和平面高度。双眼线索需要两只眼睛：视网膜像差（双眼视网膜图像的差异）和辐辏（看近物时双眼向内转动）。
Gibson’s direct theory (1966) argues that perception is innate and driven by the environment; we directly pick up information from the optic array without needing prior knowledge. Key concepts include affordances (what an object offers us) and optic flow (the pattern of motion when we move).)
Gibson 的直接理论（1966）认为知觉是天生的，由环境驱动；我们直接从光阵中提取信息，无需先前知识。关键概念包括功能承受（物体为我们提供的行为可能）和光流（我们移动时的运动模式）。
Gregory’s constructivist theory (1970) claims perception involves top-down processing where we actively construct our perception using past experiences, expectations, and hypotheses. Visual illusions occur because our perceptual hypotheses are wrong. The Muller-Lyer illusion (lines of the same length with inward- or outward-pointing fins) and the Ponzo illusion (two identical bars across converging lines) are explained by misapplied size constancy and depth cues.
Gregory 的构建理论（1970）主张知觉涉及自上而下的加工，我们利用以往经验、期望和假设主动构建知觉。视错觉之所以发生，是因为我们的知觉假设有误。Muller-Lyer 错觉（带朝内或朝外箭头的等长线段）和 Ponzo 错觉（置于汇聚线上的两根相同横条）可以用错误运用的尺寸恒常性和深度线索来解释。
Culture affects perception. Hudson (1960) found that African participants who had not seen 2D drawings were less likely to perceive depth in pictures, supporting the role of experience. Emotion (e.g., anxious people may see threats faster) and motivation (e.g., hungry people see food as brighter) can also bias perception.
文化影响知觉。Hudson（1960）发现，没有看过二维图画的非洲被试较不易在图片中感知深度，支持了经验的作用。情绪（如焦虑者更快地看到威胁）和动机（如饥饿者觉得食物更亮）也会使知觉产生偏差。
4. Development | 发展心理学
Piaget’s theory of cognitive development proposes four stages. In the sensorimotor stage (0–2 years), infants learn through senses and actions, developing object permanence. The preoperational stage (2–7 years) features egocentrism (inability to see others’ viewpoints) and inability to conserve quantity. In the concrete operational stage (7–11 years), children can classify objects and pass conservation tasks but struggle with abstract ideas. The formal operational stage (11+ years) enables abstract and hypothetical thinking.
皮亚杰的认知发展理论提出四个阶段。感知运动阶段（0–2岁）婴儿通过感官和动作学习，发展客体永久性。前运算阶段（2–7岁）表现出自我中心（不能理解他人视角）和无法守恒。具体运算阶段（7–11岁）儿童能分类并完成守恒任务，但难于抽象思维。形式运算阶段（11岁以上）能够进行抽象和假设性思维。
Piaget’s conservation tasks were criticised. McGarrigle & Donaldson (1974) used a ‘naughty teddy’ that accidentally rearranged counters, and more children correctly said the number stayed the same than in Piaget’s original procedure. This suggests the task’s social demands influenced performance. Hughes (1975) used a ‘policeman doll’ task and found younger children were less egocentric when the situation made sense to them.
皮亚杰的守恒任务受到批评。McGarrigle & Donaldson（1974）用一只“淘气泰迪”不小心弄乱了计数器，相比皮亚杰的原程序，更多儿童正确说出数量不变。这表明任务的社会要求影响了表现。Hughes（1975）用“警察娃娃”任务发现，儿童在情境有意义时并不那么自我中心。
Vygotsky stressed the role of social interaction. He introduced the zone of proximal development (ZPD) – the gap between what a child can do alone and what they can achieve with guidance. Scaffolding is the help given by a more knowledgeable other (MKO) within the ZPD. Language is a crucial tool for thought, according to Vygotsky.
维果茨基强调社会互动的作用。他提出了最近发展区（ZPD）——儿童独立所能达到的水平与在指导下能达到的水平之间的差距。支架是在 ZPD 内由知识更丰富的他人（MKO）提供的帮助。维果茨基认为语言是思维的重要工具。
Dweck’s mindset theory distinguishes between a fixed mindset (believing ability is innate) and a growth mindset (believing ability can improve with effort). Praising effort rather than ability encourages a growth mindset, leading to greater persistence and resilience in learning.
德韦克的心智模式理论区分了固定型思维（相信能力是天生的）和成长型思维（相信能力可通过努力提高）。表扬努力而非能力能鼓励成长型思维，从而增强学习中的韧性和坚持力。
5. Social Influence | 社会影响
Conformity is a change in behaviour or belief to fit in with a group. Asch (1951) showed that in a unambiguous line-matching task, about 37% of participants gave wrong answers to conform with a unanimous majority. Conformity increased with larger group size (up to about four people) and decreased when the task was very difficult or when there was another dissenter.
从众是为融入群体而改变行为或信念。Asch（1951）显示，在一个明确的线条匹配任务中，大约37%的被试给出了错误答案以符合一致的大多数意见。从众程度随群体规模增大（约增至四人）而上升，当任务非常困难或有另一个异议者时则下降。
Obedience to authority was famously investigated by Milgram (1963). Ordinary men were instructed to give increasingly strong electric shocks to a ‘learner’. Despite signs of distress, 65% administered the maximum 450V. Situation factors such as proximity of the authority figure (being in the same room), location (prestigious university), and uniform increased obedience.
对权威的服从由 Milgram（1963）进行了著名研究。普通人被指令对“学习者”施加越来越强的电击。尽管学习者的痛苦信号明显，仍有65%的被试施加了最高450伏电压。情境因素如权威人物的接近性（同处一室）、地点（有名望的大学）和制服都会增加服从程度。
The bystander effect is the tendency for individuals to help less when others are present. Latane & Darley (1968) identified factors: diffusion of responsibility (assuming others will act), pluralistic ignorance (looking to others to define the situation), and cost-benefit analysis (weighing personal risk). In the case of Kitty Genovese, multiple witnesses did not intervene, though later analysis revealed complexities.
旁观者效应是指有他人在场时个体出手相助的倾向降低。Latane & Darley（1968）识别出若干因素：责任扩散（假设别人会行动）、多数无知（参照他人来定义情境），以及成本-收益分析（权衡个人风险）。在 Kitty Genovese 案件中，多名旁观者未干预，尽管后来的分析揭示了复杂情况。
Deindividuation occurs when people lose their sense of individual identity in a crowd, leading to a loosening of normal restraints on behaviour. Zimbardo’s Stanford Prison Experiment (1973) demonstrated how quickly participants assigned to roles of guards or prisoners adopted extreme behaviours, though ethical issues were severe.
去个体化发生在个体在人群中丧失个人身份感时，导致对行为的正常约束减弱。Zimbardo 的斯坦福监狱实验（1973）展示了被分派扮演警卫或囚犯角色的参与者是如何迅速表现出极端行为的，尽管该实验存在严重的伦理问题。
6. Language, Thought and Communication | 语言、思维与沟通
The Sapir-Whorf hypothesis suggests that language determines thought (linguistic determinism) or at least influences it (linguistic relativity). For example, some cultures have many words for snow, which might affect how they perceive it. However, evidence is mixed, and most psychologists favour a weaker version of the hypothesis.
萨丕尔-沃尔夫假设提出语言决定思维（语言决定论），或至少影响思维（语言相对论）。例如，某些文化中有许多关于雪的词语，这可能影响他们怎样知觉雪。但证据混杂，多数心理学家更倾向于该假设的弱版本。
Human language is uniquely complex. It has properties such as productivity (creating infinite novel sentences), displacement (talking about things not present), and arbitrariness (no natural link between word and meaning). Studies with apes like Washoe (Gardner & Gardner, 1969) who learned over 130 ASL signs, and Kanzi, a bonobo who used lexigrams, suggest that non-human animals can acquire some aspects of language but lack full syntax and productivity.
人类语言具有独特的复杂性。它具备多产性（创造无限新句子）、位移性（谈论不在场的事物）和任意性（词与意义之间没有自然联系）等特性。对猿类的研究，如 Washoe（Gardner & Gardner, 1969）学会了130多个美国手语手势，以及使用图形符号的倭黑猩猩 Kanzi，表明非人类动物可以习得某些语言要素，但缺乏完整的句法和多产性。
Non-verbal communication includes eye contact, facial expressions, and body language. Ekman (1972) identified six basic emotions (happiness, sadness, fear, anger, surprise, disgust) that are expressed universally through facial expressions, even in isolated cultures. Eye contact can convey confidence or threat depending on context. Personal space varies between cultures (closer in Latin America, farther in North America) and between sexes (women distance themselves less with close friends).
非言语沟通包括目光接触、面部表情和身体语言。Ekman（1972）识别出六种基本情绪（快乐、悲伤、恐惧、愤怒、惊讶、厌恶），这些情绪的面部表情具有跨文化普遍性，即使在隔绝的文化中也如此。目光接触依情境可传递自信或威胁。个人空间因文化（拉美较近，北美较远）和性别（女性与密友距离更小）而异。
7. Mental Health | 心理健康
Abnormality is defined in several ways: deviation from social norms (behaviour breaking implicit rules), failure to function adequately (inability to cope with day-to-day life), statistical infrequency (rare traits), and deviation from ideal mental health (Jahoda’s criteria like self-actualisation). No single definition is perfect, and diagnoses often combine criteria.
对异常的界定有多种方式：偏离社会规范（打破隐含规则的行为）、功能失调（无法应付日常生活）、统计上的罕见（罕见的特质），以及偏离理想心理健康（Jahoda 的标准，如自我实现）。任何单一界定都不完美，诊断时常结合多种标准。
Depression is a mood disorder characterised by low mood, loss of interest, and fatigue. Biological explanations focus on low levels of serotonin and genetic predisposition. Psychological explanations include Beck’s negative triad (negative views of self, world, future) and learned helplessness (Seligman). Treatments include drug therapy (SSRIs to increase serotonin) and cognitive behavioural therapy (CBT), which challenges irrational thoughts.
抑郁症是一种心境障碍，特征为情绪低落、兴趣丧失和疲劳。生物学解释关注血清素水平低和遗传易感性。心理学解释包括贝克的负性认知三联征（对自我、世界和未来的消极看法）以及习得性无助（Seligman）。治疗方法包括药物疗法（SSRI 提高血清素）和认知行为疗法（CBT），后者挑战非理性思维。
Phobias are intense, irrational fears. They can be acquired through classical conditioning (e.g., Little Albert: Watson & Rayner, 1920) and maintained by operant conditioning (avoidance reduces anxiety, reinforcing the phobia). Treatments include systematic desensitisation (gradual exposure paired with relaxation) and flooding (immediate full exposure until anxiety subsides).
恐怖症是强烈、非理性的恐惧。可通过经典条件作用获得（如小阿尔伯特实验：Watson & Rayner, 1920），并通过操作性条件作用维持（回避减轻焦虑，从而强化恐怖症）。治疗方法包括系统脱敏（逐步暴露结合放松）和冲击疗法（立即充分暴露直至焦虑消退）。
Addiction involves dependence on a substance or activity. Biological influences include dopamine reward pathways and genetic vulnerability. Psychological factors involve learning through positive reinforcement. Aversion therapy pairs the addictive substance with an unpleasant stimulus (e.g., nausea-inducing drug), while self-management programmes teach coping strategies and goal setting.
成瘾涉及对物质或活动的依赖。生物因素包括多巴胺奖赏通路和遗传易感性。心理因素涉及通过正强化学习。厌恶疗法将成瘾物质与不愉快刺激配对（如致恶心药物），而自我管理方案则教授应对策略和目标设定。
8. Exam Focus and Revision Strategies | 考试重点与复习策略
For Year 10 CIE Psychology, it is essential to know key studies by name, date, and procedure. In exam questions, especially 9-markers, you need to describe a study and then evaluate it in terms of methodology, ethics, and alternative explanations. Always link your points back to the question stem.
对于 Year 10 CIE 心理学，熟记关键研究的名称、日期和步骤至关重要。在考试中，特别是9分题，你需要描述一项研究，然后从方法、伦理和替代解释角度进行评价。始终将你的论点与题干相联系。
When revising, create mind maps for each topic and use dual coding (combine words and pictures). Practise comparing theories directly, e.g., Gibson vs Gregory on perception. Use flashcards for studies with the APRC format (Aim, Procedure, Results, Conclusion). Attempt past paper questions under timed conditions and note the level of detail expected in ‘Describe’ vs ‘Evaluate’ questions.
复习时，为每个主题绘制思维导图，使用双重编码（词与图结合）。练习直接比较理论，如 Gibson 与 Gregory 的感知理论。使用
