1. The Scientific Method: Key Variables | 科学方法：关键变量
In any psychology experiment, the independent variable (IV) is the factor that the researcher deliberately manipulates or changes. Think of it as the 'cause' in a cause-and-effect relationship. To recall this easily, remember I for Independent and I for 'I change it' — the researcher is in charge of altering the IV.
在任何心理学实验中，自变量 (IV) 是研究者故意操纵或改变的因素。你可以把它理解为因果关系中的“因”。要轻松记住它，记住 I 代表 Independent，也代表 'I change it'（我来改变它）—— 研究者负责改变自变量。
The dependent variable (DV) is what is measured; it depends on the participants' responses and, hopefully, on the changes made to the IV. A simple memory trick is to associate D for Dependent with 'Data' — it is the data you collect that depends on the independent variable. Imagine an experiment on the effect of music on memory recall. The IV is the type of music (or silence), and the DV is the number of words recalled.
因变量 (DV) 是被测量的结果；它取决于参与者的反应，并且有赖于自变量的改变。一个简单的记忆窍门是把 D for Dependent 与 'Data'（数据）联系起来——它是你收集的、依赖于自变量的数据。想象一个研究音乐对记忆回忆影响的实验。自变量是音乐类型（或安静环境），因变量是回忆出的单词数量。
2. Hypotheses and Aims | 假设与目标
An aim is a general statement of purpose, explaining what the researcher intends to investigate. For example, 'To investigate whether sleep affects attention.' An aim is broad and does not predict an outcome. Think of an aim as the 'goalpost' — it sets the direction without telling you which way the ball will go.
研究目标 (aim) 是一个概括性的目的陈述，说明研究者打算探索什么。例如，“探究睡眠是否影响注意力。” 目标是宏观的，不预测结果。可以把目标想象成“球门柱”——它设定了方向，却不告诉你球会飞向哪边。
A hypothesis, on the other hand, is a precise, testable prediction about the relationship between variables. A good hypothesis must include both an IV and a DV and state how they are connected. Use the mnemonic 'HIP' — Hypothesis Includes a Prediction. For the sleep study, a hypothesis could be: 'Participants who sleep for 8 hours will score significantly higher on an attention test than those who sleep for only 4 hours.'
而假设 (hypothesis) 则是一个精确、可检验的关于变量关系的预测。一个好的假设必须包含自变量和因变量，并说明它们如何关联。使用助记符 'HIP' —— Hypothesis Includes a Prediction（假设包含预测）。对于睡眠研究，假设可以是：“睡眠8小时的参与者在注意力测试中的得分会显著高于仅睡4小时的参与者。”
3. Sampling and Participants | 抽样与参与者
The target population is the entire group that a researcher is interested in studying and drawing conclusions about. It can be huge, like 'all teenagers in the UK'. Since it is usually impossible to test everyone, researchers select a sample, a smaller, manageable subset. Remember the phrase 'Sample is just a Slice of the Pie' — the population is the whole pie, and the sample is the slice you actually examine.
目标总体 (target population) 是研究者感兴趣并希望得出结论的整个群体。它可以很庞大，比如“全英国所有青少年”。由于通常不可能对每个人都进行测试，研究者会选择一个样本 (sample)，一个更小、更易处理的子集。记住这个说法“样本只是馅饼的一块”——总体是整个馅饼，而样本是你实际品尝的那一片。
A participant is an individual who takes part in a study. It is more respectful and accurate than calling them 'subjects'. When thinking about sampling methods, watch out for sampling bias, which happens when a sample is not representative of the target population. To avoid bias, researchers might use a random sample. The memory link: 'Fair is Fair — Random is Like a Lottery.' Everyone has an equal chance of being picked.
参与者 (participant) 是参加研究的个人。这个称呼比“被试”更尊重、更准确。在考虑抽样方法时，要警惕抽样偏差 (sampling bias)，当样本不能代表目标总体时就会发生。为了避免偏差，研究者可能采用随机抽样。记忆关联：“公平就是公平——随机就像抽奖。”每个人都有同等被选中的机会。
4. Research Designs | 研究设计
An experiment is a research method where the researcher manipulates an IV to measure its effect on a DV, while controlling other variables. It is the only method that can establish cause and effect. Think 'Expert manipulation' — only an experiment can expertly reveal causation. A laboratory experiment takes place in a controlled, artificial environment, offering high control but lower ecological validity.
实验 (experiment) 是一种研究方法，研究者操纵自变量以测量其对因变量的影响，同时控制其他变量。这是唯一能确定因果关系的方法。想想“专家级操纵”——只有实验才能专业地揭示因果关系。实验室实验 (laboratory experiment) 在受控的人工环境中进行，控制度高但生态效度较低。
A correlation measures the relationship between two co-variables, but it does not imply causation. The word 'correlation' contains 'co' and 'relation' — a co-relationship. A positive correlation means as one variable rises, the other also tends to rise (like practice time and performance). A negative correlation means as one goes up, the other goes down (like stress and sleep quality). Never say 'causes' when describing a correlation. The rhyme 'Correlation is not causation' will save you every time.
相关 (correlation) 衡量两个共变量之间的关系，但它不意味着因果关系。单词 'correlation' 包含 'co' 和 'relation' —— 一种共同关系。正相关意味着一个变量上升，另一个也往往上升（如练习时间与成绩）。负相关意味着一个变量上升，另一个下降（如压力与睡眠质量）。在描述相关时绝不要说“导致”。那句顺口溜“相关不等于因果”每次都会救你一命。
An observation is a non-experimental method where behaviour is watched and recorded in a natural or controlled setting. Key terms include overt observation (participants know they are being watched) and covert observation (they do not). Link 'overt' with 'open' and 'covert' with 'covered' or hidden.
观察法 (observation) 是一种非实验方法，在自然或受控环境中观察并记录行为。关键术语包括公开观察 (overt observation) —— 参与者知道自己在被观察，以及隐蔽观察 (covert observation) —— 他们并不知情。把 'overt' 和 'open'（公开）关联，把 'covert' 和 'covered'（遮盖）或隐藏关联。
5. Data Types and Measures | 数据类型与测量
Quantitative data is numerical information, such as scores, reaction times, or the number of times a behaviour occurs. It is easy to analyse statistically but may lack depth. The word 'Quantitative' reminds you of 'Quantity' — it is about numbers and counts. Qualitative data, by contrast, is descriptive and non-numerical, like interview transcripts, open-ended questionnaire answers, or diary entries. It captures the 'Quality' of human experience.
定量数据 (quantitative data) 是数值信息，例如分数、反应时间或某种行为发生的次数。它容易进行统计分析，但可能缺乏深度。单词 'Quantitative' 让你联想到 'Quantity'（数量）——它关乎数字和计数。而定性数据 (qualitative data) 是描述性的、非数值的，比如访谈记录、开放式问卷答案或日记。它捕捉人类体验的“品质”。
When measuring data, you will encounter the four scales. Nominal data is data in categories with no order (e.g., eye colour: blue, brown, green). Think 'Nominal' as 'Name only'. Ordinal data can be ranked in an order but the gaps between ranks are not equal (e.g., 1st, 2nd, 3rd in a race — you don't know the time difference). 'Ordinal' shares its root with 'Order'. Interval data has equal intervals but no true zero (e.g., temperature in °C). Ratio data has equal intervals and a true zero, meaning you can say twice as much (e.g., height, weight). The mnemonic 'N O I R' — Nominal, Ordinal, Interval, Ratio — helps you remember all four.
在测量数据时，你会遇到四种量表。称名数据 (nominal data) 是无顺序的类别数据（例如，眼睛颜色：蓝色、棕色、绿色）。把 'Nominal' 想成 'Name only'（仅名字）。顺序数据 (ordinal data) 可以按顺序排列，但各排列之间的差距并不相等（例如，比赛中的第1、2、3名——你不知道时间差距）。'Ordinal' 与 'Order'（顺序）有相同的词根。等距数据 (interval data) 具有相等的间隔但没有真正的零点（例如，摄氏温度）。等比数据 (ratio data) 有相等的间隔且有真正的零点，因此你可以说某个值是另一个的两倍（例如，身高、体重）。助记符 'N O I R' —— Nominal, Ordinal, Interval, Ratio —— 帮你记住全部四种。
6. Descriptive Statistics | 描述性统计
The mean is the arithmetic average of all scores. It is highly sensitive to extreme scores (outliers). To remember, 'Mean is the average machine' — it churns out a central value but can break down if an outlier crashes in. The median is the middle score when data are arranged in order. It is robust against outliers. Think of a road 'median' strip — it sits right in the middle.
平均数 (mean) 是所有分数的算术平均。它对极端分数（异常值）非常敏感。为了记忆，“平均数是一台平均值机器”——它产出一个中心值，但如果有异常值闯入就可能出故障。中位数 (median) 是数据按顺序排列时的中间分数。它不受异常值影响。想象道路中间的“中央分隔带 (median strip)”——它就位于正中间。
The mode is the most frequently occurring value. It is the only measure that can be used with nominal data. Say 'Mode = Most' to lock it in. Range st value. Think of a mountain range stretching from the lowest valley to the highest peak.
众数 (mode) 是出现频率最高的值。它是唯一可用于称名数据的测量。念叨“众数就是最多 (Mode = Most)”以牢记。全距 (range) 是从最低分到最高分的分散度。快速公式：全距 = 最大值 - 最小值。想象一条山脉从最低的山谷绵延至最高的山峰。
7. Ethical Principles | 伦理原则
All psychologists must follow strict ethical guidelines to protect participants. Informed consent means participants must be given clear, understandable information about the study and must agree to take part without being pressured. Watch out for the 'Informed' part — they must know what they're signing up for. If a participant is under 16, consent from a parent or guardian is also needed.
所有心理学家都必须遵守严格的伦理准则以保护参与者。知情同意 (informed consent) 意味着必须向参与者提供清晰易懂的研究信息，并且他们必须在无压力下同意参与。注意“知情”部分——他们必须知道他们报名参与的是什么。如果参与者未满16岁，还需要父母或监护人的同意。
Confidentiality is the obligation to protect participants' personal data and not disclose their identities. A memory hook: 'Confidential files stay confidential forever.' Deception should be avoided whenever possible; if it is essential to the design, participants must be debriefed as soon as possible afterwards. Debriefing involves revealing the true purpose of the study and restoring participants to the state they were in before. Think of it as an 'un-deceiving' session.
保密 (confidentiality) 是保护参与者个人数据、不泄露其身份的义务。记忆钩子：“秘密文件永远保持秘密状态。” 欺骗 (deception) 应尽可能避免；若对研究设计不可或缺，事后必须尽快对参与者进行事后说明 (debriefing)。事后说明包括揭示研究的真正目的，并将参与者恢复到参与前的状态。把它想象成一次“解除欺骗”的环节。
The right to withdraw allows participants to leave the study at any time without penalty, and even to request that their data be removed. Remember 'Right to Withdraw — Right to Walk out the Door.' Protection from harm covers both physical and psychological well-being. Participants should leave a study in no worse condition than they arrived.
退出权 (right to withdraw) 允许参与者随时退出研究而不会受到惩罚，甚至可以要求删除其数据。记住“退出权——走出大门的权利。” 避免伤害 (protection from harm) 涵盖身心两方面。参与者离开研究时，其状态不应比参与前更差。
8. Validity and Reliability | 效度与信度
Validity asks whether a test or study actually measures what it claims to measure. Internal validity concerns whether the IV is the only factor affecting the DV — have you controlled confounding variables? External validity, or ecological validity, is about whether findings can be generalised to real-life settings. A simple analogy: validity is like throwing a dart and hitting the bullseye that you were aiming at.
效度 (validity) 问的是测试或研究是否真正测量了它声称要测量的东西。内部效度 (internal validity) 关注自变量是否是影响因变量的唯一因素——你是否控制了混淆变量？外部效度 (external validity) 或生态效度，关乎研究结果能否推广到真实生活情境。一个简单类比：效度就像投掷飞镖并命中你瞄准的靶心。
Reliability means consistency. If you repeat the measurement under the same conditions, will you get a very similar result? A reliable bathroom scale gives you the same reading if you step on and off three times quickly. Think of a 'reliable friend' — someone you can count on to be consistent. A study can be reliable without being valid (e.g., a broken scale that consistently reads 5 kg too heavy), but a valid study must first be reliable.
信度 (reliability) 指的是一致性。如果在相同条件下重复测量，你会得到非常相似的结果吗？一台可靠的人体秤会让你快速上下三次都显示相同读数。想想一个“可靠的朋友”——一个你可以信赖、始终如一的人。一项研究可以在无效的情况下具有高信度（例如，一台每次称重都多5公斤的破秤），但一个有效的研究首先必须是可靠的。
9. Cognitive Psychology Terms | 认知心理学术语
Cognitive psychology explores internal mental processes like memory, perception, and thinking. A central model you will encounter is the multi-store model of memory, which proposes three separate stores: sensory register, short-term memory (STM), and long-term memory (LTM). Remember 'STM' as 'Store Temporarily' because its capacity is limited (around 7+/-2 chunks) and duration is brief (about 18–30 seconds without rehearsal).
认知心理学 (cognitive psychology) 探索内部心理过程，如记忆、感知和思维。你会遇到的一个中心模型是记忆的多重储存模型 (multi-store model of memory)，它提出三个独立的储存库：感觉登记、短时记忆 (STM) 和长时记忆 (LTM)。把 'STM' 记作“暂时储存 (Store Temporarily)”，因为它的容量有限（约7±2个组块），持续时间短（没有复述约为18–30秒）。
Long-term memory (LTM) has seemingly unlimited capacity and duration. It is subdivided into episodic memory (personal events, like your last birthday), semantic memory (facts and knowledge, like the capital of France), and procedural memory think: Episodic = Episodes of your life; Semantic = encyclopaedic knowledge; Procedural = 'Pro' skills you perform automatically.
长时记忆 (LTM) 有着看似无限的容量和时长。它被细分为情景记忆 (episodic memory)（个人事件，如你上一个生日）、语义记忆 (semantic memory)（事实与知识，如法国首都）和程序性记忆 (procedural memory)（技能，如骑自行车）。要区分它们，可联想：情景记忆 = 你生活中的片段 (Episodes)；语义记忆 = 百科全书式的知识；程序性记忆 = 你自动执行的“专业 (Pro)”技能。
Rehearsal is the conscious repetition of information to extend its stay in STM and help transfer it to LTM. Chunking is grouping separate pieces of information into larger, meaningful units (e.g., remembering a phone number as 077 112 3344 rather than 0771123344). This greatly increases the capacity of STM. Visualise a 'chunk' of chocolate — broken into manageable pieces to digest easily.
复述 (rehearsal) 是有意识重复信息以延长其在短时记忆中的停留，帮助转移到长时记忆。组块 (chunking) 是将独立的信息片段组合成更大、有意义单元（例如，记电话号码为077 112 3344而不是0771123344）。这大大提高了短时记忆的容量。想象一块巧克力——掰成易于入口的小块来消化。
10. Social Psychology Terms | 社会心理学术语
Conformity is a type of social influence where an individual changes their belief or behaviour to fit in with a group. This can occur due to normative social influence (wanting to be liked and accepted) or informational social influence (believing the group is better informed). Memory aid: 'Normative = Need to belong; Informational = I'm uncertain, others must know.'
从众 (conformity) 是一种社会影响，个体改变信仰或行为以适应群体。这可能源于规范性社会影响 (normative social influence)（渴望被喜欢和接纳）或信息性社会影响 (informational social influence)（相信群体有更好的信息）。记忆辅助：“规范性 = 归属需求 (Need)；信息性 = 我不确定，他人一定知道 (I'm unsure, others know)。”
Obedience involves following direct orders from an authority figure. It differs from conformity because there is an explicit command, not just unspoken group pressure. Think of a teacher or police officer giving a direct instruction — obedience is complying with that hierarchy. A well-known study on obedience is Milgram's electric shock experiment, but remember the ethical issues of that study for your exams.
服从 (obedience) 涉及遵从权威人物的直接命令。它不同于从众，因为存在明确的指令，而不仅仅是无声的群体压力。想想老师或警察给出直接指示——服从就是遵从那个等级体系。关于服从的一个著名研究是米尔格拉姆的电击实验，但考试时要记得该研究的伦理问题。
Bystander effect is the finding that the more people are present at an emergency, the less likely any one individual is to help. This is partly due to diffusion of responsibility: 'I don't need to act, someone else will.' The mnemonic here is 'Bystander = By stand — just standing by, waiting for another person to step up.'
旁观者效应 (bystander effect) 是指突发事件中在场的人越多，单一个体出手相助的可能性就越小。部分原因是责任分散 (diffusion of responsibility)：“我不需要行动，别人会的。”这里的助记是“旁观者 = 在旁边站着——只是站在一旁，等着别人出头。”

12. Final Revision Strategies | 终极复习策略
Do not just read these definitions passively. Engage actively by covering the English or Chinese text and trying to recall the other. Create your own flashcards with the key term on one side and the memory hook on the reverse. Use the terms in your own sentences when writing practice exam answers — the more you use them in context, the more naturally they will come to you on exam day. Good luck, and remember psychology vocabulary is your toolkit for understanding the mind!
不要只是被动地阅读这些定义。主动参与：遮住英文或中文部分，尝试回忆另一方。制作你自己的闪卡，一面写关键词，另一面写记忆钩子。在练习考试题目时用这些术语造自己的句子——你越多在语境中使用它们，它们就越会在考试日自然而然地涌现出来。祝你好运，记住心理学词汇是你理解心灵的工具箱！
