欢迎阅读 Year 7 CAIE 心理学复习指南。本文梳理了考试中最高频出现的主题，并重点分析学生常犯的典型错误。掌握这些常见的失分点，可以帮助你优化答案、提升应考信心。我们将一起探索心理学导论的核心领域，从研究方法到社会影响和记忆，精准聚焦考官的评分要点。
1. What is Psychology and How Do We Study It? | 什么是心理学？我们如何研究它？
Psychology is the scientific study of mind and behaviour. In Year 7, you learn that psychologists use empirical methods – observations, experiments, and questionnaires – to gather evidence. A high-frequency exam question asks you to distinguish between ‘common sense’ beliefs and psychological findings. A common mistake is stating that psychology is just talking about feelings or that it proves what everyone already knows. Instead, you must highlight that psychology tests ideas with controlled research.
心理学是对心理和行为的科学研究。在七年级，你要学习心理学家如何使用实证方法——观察、实验和问卷调查——来收集证据。高频考点中常会要求你区分“常识”信念和心理学发现。常见的错误是认为心理学只是谈论感受，或者只是证明人尽皆知的事情。正确的回答是要强调心理学通过控制研究来检验观点。
For example, a question might ask: ‘How is psychological research different from everyday opinion?’ The expected answer emphasises systematic data collection, objectivity and replication. Students often lose marks by giving vague answers like ‘it is more scientific’ without explaining what that means.
例如，题目可能问：“心理学研究与日常观点有何不同？”正确的答案应强调系统化的数据收集、客观性和可重复性。学生常常因为回答得过于模糊，比如“它更科学”，却没有解释其具体含义而丢分。
2. Independent and Dependent Variables | 自变量与因变量
Identifying variables is one of the most heavily tested skills. The independent variable (IV) is the factor the researcher changes or manipulates. The dependent variable (DV) is what the researcher measures. A typical easy-to-miss error is labelling the DV as the thing you ‘change’ because you are measuring a change. Always ask: ‘What did the experimenter alter on purpose?’ (IV) and ‘What result was recorded?’ (DV).
识别变量是考查频率最高的技能之一。自变量（IV）是研究者改变或操纵的因素。因变量（DV）是研究者测量的结果。一个容易犯的典型错误是把因变量当作“改变的东西”，因为你测量的是变化。一定要问自己：“实验者有目的地改变了什么？”（IV）以及“记录了什么样的结果？”（DV）。
Below is a table of common scenarios that often appear in Year 7 exams, along with the frequent mistake of swapping the variables.
下面是一个经常出现在七年级考试中的情境表格，同时列出了变量混淆的常见错误。
| Study description | Correct IV | Correct DV | Common mistake |
|---|---|---|---|
| Does background music affect test scores? | Presence or type of music | Test score | Saying the IV is ‘test score’ because it changes |
| Does the amount of sleep influence reaction time? | Hours of sleep | Reaction time (ms) | Thinking sleep is the DV because it’s the result |
3. Experimental Designs: Independent Groups vs Repeated Measures | 实验设计：独立组与重复测量
Year 7 students must know two basic experimental designs. In an independent groups design, different participants are used in each condition. In a repeated measures design, the same participants take part in all conditions. The high-frequency pitfall is mixing up the advantages and disadvantages. For instance, many write that repeated measures ‘needs more participants’, which is the opposite: it uses the same people, so fewer participants are needed.
七年级学生必须掌握两种基本实验设计。在独立组设计中，不同条件下的参与者是不同的人。在重复测量设计中，同一批参与者会经历所有条件。高频错误是混淆了各自的优缺点。例如，很多人写“重复测量需要更多参与者”，这恰恰相反：重复测量使用的是同一批人，因此需要的参与者更少。
Another classic exam question asks to identify the design from a description. A typical wrong answer selects ‘repeated measures’ just because the test is repeated, overlooking whether the same people did both tasks. Always check if the same group was used twice.
另一个经典考题是根据描述判断实验设计。典型的错误答案是，仅仅因为测试重复进行就选择了“重复测量”，而忽略了是否真的是同一批人完成了两项任务。务必检查同一组被试是否被使用了两次。
4. The Multi-Store Model of Memory | 记忆的多存储模型
The multi-store model (Atkinson and Shiffrin) describes three stores: sensory register, short-term memory (STM), and long-term memory (LTM). High-frequency questions ask for the capacity and duration of STM. The correct capacity is 7±2 items, and duration is about 18–30 seconds without rehearsal. A very common mistake is stating STM duration as ‘a few minutes’ or confusing its capacity with LTM’s unlimited capacity.
多存储模型（阿特金森和希弗林）描述了三个存储系统：感觉登记、短时记忆（STM）和长时记忆（LTM）。高频考点要求写出短时记忆的容量和持续时间。正确的容量是 7±2 个组块，持续时间为不进行复述的情况下约 18–30 秒。一个极为常见的错误是把短时记忆的持续时间说成“几分钟”，或者将其容量与长时记忆的无限容量混淆。
STM capacity = 7 ± 2 items
Students also lose marks by not mentioning the role of rehearsal in transferring information to LTM. If a question asks how information moves from STM to LTM, you must state ‘maintenance rehearsal’ or simply ‘repeating it’.
学生还常因为没有提到复述在信息转入长时记忆过程中的作用而丢分。如果题目问信息如何从短时记忆进入长时记忆，你必须答出“维持性复述”或“重复信息”。
5. Explanations of Forgetting | 遗忘的原因
Two key explanations appear in Year 7 exams: decay and displacement. Decay suggests that memories fade over time if not used. Displacement occurs in STM when new information pushes out old information because the capacity is limited. The classic error is using decay to explain forgetting from STM when the question clearly describes a situation where capacity is overloaded. For STM, displacement is usually the better explanation; decay is more appropriate for sensory or long-term memory.
七年级考试中常见的两种遗忘解释是：消退和干扰/位移。消退理论认为，如果不使用，记忆会随时间逐渐淡化。位移发生在短时记忆中，由于容量有限，新信息会把旧信息挤出。典型的错误是，当题目明确描述了容量超负荷的情境时，却用消退来解释短时记忆的遗忘。对于短时记忆，位移通常是更合适的解释；消退则更适合感觉记忆或长时记忆。
Exam tip: if the question mentions ‘new information replacing the old in a short space of time’, the answer is displacement. If it describes a memory fading after many years, decay or lack of rehearsal is correct.
考试提示：如果题目提到“新信息在短时间内取代了旧信息”，答案就是位移。如果描述的是很多年后的记忆淡化，那么消退或缺乏复述才是正确的。
6. Conformity: Majority Influence | 从众：多数人的影响
Conformity means changing your behaviour or beliefs to fit in with a group. Year 7 questions often refer to Asch’s line study as an example. A common mistake is describing conformity as simply ‘copying a friend’ without mentioning group pressure or the desire to be accepted. Markers look for phrases like ‘normative social influence’ (wanting to be liked) or ‘informational social influence’ (believing the group knows better).
从众是指为了融入群体而改变自己的行为或信念。七年级的题目常常以阿希的线段实验为例。常见的错误是把从众简单描述成“模仿朋友”，而没有提到群体压力或渴望被接纳。评分者希望你使用诸如“规范性社会影响”（希望被喜欢）或“信息性社会影响”（认为群体更懂）这样的表述。
A tricky question asks: ‘Why did participants conform in Asch’s study even when they knew the answer was wrong?’ The correct response should mention both the size of the majority and the fear of standing out. Simply saying ‘because the others said so’ is not enough.
有一道易错题会问：“为什么阿希实验中的参与者明知答案错误，仍然选择从众？”正确的回答需要同时提到多数人的规模和害怕显得与众不同。仅仅回答“因为别人都这么说”是不够的。
7. Obedience: Milgram’s Research | 服从：米尔格拉姆的研究
In Year 7, you learn about obedience through Milgram’s electric shock experiment. High-frequency exam items ask about the factors that increase obedience, such as the authority figure wearing a lab coat, proximity of the authority, and the prestige of the setting (Yale University). A typical mistake is writing that participants ‘enjoyed giving shocks’ or that they were naturally aggressive. Instead, you must explain that people obey due to the perception of legitimate authority and the agentic state – seeing themselves as merely carrying out orders.
在七年级，你通过米尔格拉姆的电击实验学习服从。高频考点会问及增加服从的因素，比如权威人物穿着实验室白大褂、权威的近距离性，以及场景的声望（耶鲁大学）。一个典型错误是写参与者“喜欢施加电击”或者他们天生具有攻击性。正确的解释应该是：人们服从是因为感知到了合法权威，以及处于“代理状态”——认为自己只是在执行命令。
Many students confuse obedience with conformity. Obedience involves a direct order from an authority figure, while conformity is about matching group norms without a direct command. This distinction is frequently tested in multiple-choice or short-answer questions.
很多学生混淆了服从和从众。服从涉及权威人物的直接命令，而从众则是没有直接命令时与群体规范保持一致。这一区别经常出现在选择题或简答题中。
8. Attachment Styles: Secure, Insecure-Avoidant, Insecure-Resistant | 依恋类型：安全型、不安全回避型、不安全矛盾型
The Strange Situation procedure is used to identify attachment types. A high-frequency question asks to describe the behaviour of a securely attached infant. The correct answer includes: explores the room when the caregiver is present, shows distress during separation, and seeks comfort upon reunion. A common error is to describe an insecure-avoidant infant (ignores caregiver, shows no distress) and call it ‘secure’ because it appears independent.
陌生情境实验被用来识别依恋类型。高频考题会要求描述安全型依恋婴儿的行为。正确答案包括：照顾者在场时会探索房间，分离时表现出痛苦，重聚时寻求安慰。常见的错误是把不安全回避型婴儿的行为（忽视照顾者、没有表现出痛苦）误称为“安全型”，因为其表现出的所谓“独立”。
Pay attention to exam questions that present scenarios and ask you to identify the attachment type. A child who clings to the caregiver but resists comfort is likely insecure-resistant. Many students incorrectly label this as secure because the child is ‘close’ to the caregiver, missing the key detail of resistance to soothing.
注意考试中会出现情景题，要求你判断依恋类型。一个紧紧黏着照顾者却抗拒安慰的孩子很可能是不安全矛盾型。很多学生会错误地将其归为安全型，只因为孩子“亲近”照顾者，却忽略了抗拒安抚这一关键细节。
9. Classical Conditioning: Pavlov’s Dogs | 经典条件作用：巴甫洛夫的狗
Classical conditioning involves learning through association. The key terms – unconditioned stimulus (UCS), unconditioned response (UCR), neutral stimulus (NS), conditioned stimulus (CS), and conditioned response (CR) – appear in almost every Year 7 CAIE paper. The most frequent mistake is confusing the UCS and CS. Remember: the UCS naturally triggers a reflex (e.g., food causes salivation), while the CS triggers the same response only after being paired with the UCS (e.g., bell after pairing).
经典条件作用涉及通过联结进行学习。关键术语——无条件刺激（UCS）、无条件反应（UCR）、中性刺激（NS）、条件刺激（CS）和条件反应（CR）——几乎出现在每份 Year 7 CAIE 试卷中。最常见的错误是混淆 UCS 和 CS。记住：UCS 是自然引发反射的（例如食物引起唾液分泌），而 CS 只有在与 UCS 反复配对后才会引发同样的反应（例如配对后的铃声）。
A typical exam question: ‘In Pavlov’s experiment, what was the conditioned stimulus?’ The correct answer is the bell. A common wrong answer is ‘food’. Students must trace the scenario step by step to avoid this mix-up.
一道典型的考题：“在巴甫洛夫的实验中，条件刺激是什么？”正确答案是铃声。而常见的错误答案是食物。学生必须逐步梳理实验流程才能避免这种混淆。
10. Operant Conditioning: Reinforcement and Punishment | 操作性条件作用：强化与惩罚
Operant conditioning explains how consequences shape behaviour. Positive reinforcement adds something pleasant to increase a behaviour. Negative reinforcement removes something unpleasant to increase a behaviour. Many students wrongly believe negative reinforcement is the same as punishment. Punishment decreases a behaviour. This misunderstanding is one of the most marked pitfalls in Year 7 psychology.
操作性条件作用解释了行为如何被结果塑造。正强化是加入愉快的事物来增加行为。负强化是移除不愉快的事物来增加行为。许多学生错误地认为负强化就是惩罚。惩罚是减少行为。这一误解是七年级心理学中最显著的学习陷阱之一。
Remember: taking a painkiller to relieve a headache is negative reinforcement (headache removed, so taking painkiller increases). Getting a detention for not doing homework is positive punishment (adding an unpleasant consequence to decrease the behaviour). If you can match the definition to the effect on behaviour, you will avoid the trap.
记住：服用止痛药来缓解头痛是负强化（头痛被移除，因此服药行为增加）。因没做作业而被留校是正惩罚（增加一个不愉快的后果来减少该行为）。只要能将定义与对行为的影响对应起来，你就不会落入陷阱。
11. Ethical Issues in Psychological Research | 心理学研究中的伦理问题
Year 7 CAIE expects you to know basic ethical guidelines: informed consent, right to withdraw, protection from harm, deception, and debriefing. A common exam mistake is stating that deception is always unethical without explaining that it can be used if there is strong scientific justification and no alternative, and if participants are debriefed afterwards. Similarly, some students write that researchers can secretly observe anyone as long as it is ‘for science’, which is incorrect.
Year 7 CAIE 要求你了解基本的伦理准则：知情同意、退出权、保护免受伤害、欺骗和事后解释。考试中常见的错误是，在不加解释的情况下宣称欺骗总是不道德的，而实际上如果有充分的科学理由且别无他法，并在事后对参与者进行了详细解释，欺骗是可以被允许的。同样，有些学生写“为了科学”研究人员就可以随意秘密观察任何人，这也是错误的。
For a high-mark answer, always link the ethical issue to a specific study, such as Milgram’s lack of protection from harm or the deception in Asch’s conformity experiment. General statements without examples rarely score full marks.
要想拿到高分，一定要将伦理问题与具体研究联系起来，比如米尔格拉姆实验中缺乏免受伤害的保护，或者阿希从众实验中的欺骗。没有例子的泛泛而谈很难获得满分。
12. Exam Technique and Common Perennial Mistakes | 考试技巧与常见顽固错误
Beyond content, Year 7 students often lose marks for the same procedural reasons. They fail to read command words: ‘describe’ means say what something is; ‘explain’ means give a reason; ‘identify’ means name or select. Another pattern is ignoring the mark allocation – a two-mark question requires two distinct points, not a single elaborated sentence.
除了知识内容，七年级学生常常因为相似的答题规范问题丢分。他们忽略了指令词：“描述”意味着说出它是什么；“解释”意味着给出一个原因；“识别”意味着命名或选择。另一个常见模式是无视分值——一道两分的题目需要两个不同的得分点，而不是一个冗长的长句。
Also, do not leave answers blank. A guess based on the topic could earn partial credit. For ‘evaluate’ or ‘discuss’ questions, always give at least one strength and one weakness, even if the question seems one-sided.
同样，不要留空白。根据题目所属的话题进行猜测，有可能拿到部分分数。对于“评价”或“讨论”类问题，即便题目看起来是单方面的，也至少要分别给出一个优点和一个缺点。
Finally, always review your variable definitions and design distinctions right before the exam. These core concepts underpin almost every topic and are the most heavily weighted mistakes across the entire Year 7 CAIE Psychology assessment.
最后，在考试前一定要再复习一遍变量定义和实验设计的区别。这些核心概念支撑着几乎每一个话题，也是整个 Year 7 CAIE 心理学考评中权重最高的失分点。
