1. Overview of the Mock Unit Test | 模拟单元测试概述
The mock paper is designed to simulate a 45-minute unit test covering three core areas: memory (cognitive psychology), attachment (developmental psychology), and conformity (social psychology). It also integrates research methods and ethical considerations throughout. The paper includes 5 multiple-choice questions (MCQs), 4 short-answer questions requiring definitions, applications or brief evaluations, and 1 extended response question that asks for a critical evaluation of a named study. All questions are drawn from the CAIE 0475 syllabus and are typical of those found in past papers.
本模拟卷旨在模拟一场45分钟的单元测试，覆盖记忆（认知心理学）、依恋（发展心理学）和从众（社会心理学）三个核心领域。试卷贯穿了研究方法和伦理考量。试题包括5道选择题、4道需要下定义、应用或简要评价的简答题，以及1道要求对某项指定研究进行批判性评价的拓展回答题。所有题目均源自CAIE 0475大纲，并常见于历年真题。
The following sections present each question or question cluster with its correct answer, followed by a detailed analysis of why that answer is correct and how other options are misleading. For short-answer questions, we provide model answers that would gain full marks, along with examiner commentary to highlight what makes a strong response.
下列各部分呈现每道题或题组及其正确答案，随后详细解析为何该答案正确、其他选项为何有误导性。对于简答题，我们给出了可得满分的参考答案，并附上考官点评，突出高分回答的关键。
2. Question 1: Research Methods Terminology | 题目1：研究方法术语
MCQ: 'In an experiment, the variable that the researcher measures is called the...' A) Independent variable B) Dependent variable C) Extraneous variable D) Confounding variable
选择题：“在实验中，研究者测量的变量称为……”A) 自变量 B) 因变量 C) 额外变量 D) 混淆变量
Correct answer: B) Dependent variable. The dependent variable (DV) is the factor that is measured by the researcher to investigate the effect of the independent variable. The independent variable (IV) is the factor that is manipulated or changed. Extraneous variables are any variables other than the IV that could affect the DV if not controlled. A confounding variable is an extraneous variable that has indeed affected the DV, making it difficult to determine whether the IV caused the effect.
正确答案：B) 因变量。因变量（DV）指研究者为考察自变量效应而测量的因素。自变量（IV）是被操纵或改变的因素。额外变量指除IV外任何可能影响DV的因素，若未加控制。混淆变量是一种已经影响了DV的额外变量，导致难以确定效应是否由IV引起。
Many students lose marks here by confusing the IV and DV. A useful mnemonic is 'I manipulate, I measure' — the Independent variable is what I change, while the Dependent variable Depends on the IV. In any experimental design question, always identify the IV and DV first, as this structures the entire hypothesis and operationalisation.
许多学生在此处因混淆IV和DV而失分。一个有用的记忆法是“我操纵，我测量”——Independent variable是我改变的变量，而Dependent variable则依赖于IV。在任何实验设计题中，务必先确定IV和DV，这构成了整个假设和操作化的基础。
3. Question 2: Memory Models – Multi-Store Model | 题目2：记忆模型——多储存模型
MCQ: 'According to Atkinson and Shiffrin's multi-store model, information passes from sensory memory into short-term memory through...' A) Rehearsal B) Attention C) Retrieval D) Elaboration
选择题：“根据Atkinson和Shiffrin的多储存模型，信息从感觉记忆进入短时记忆的途径是……”A) 复述 B) 注意 C) 提取 D) 精细加工
Correct answer: B) Attention. The multi-store model proposes that sensory memory holds a large amount of information very briefly. Only the information to which we pay attention is transferred into short-term memory (STM). Rehearsal is the process that maintains information in STM and can eventually transfer it to long-term memory (LTM). Retrieval refers to recalling information from LTM back into STM. Elaboration or elaborative rehearsal is a deeper processing strategy linked more to the levels of processing model.
正确答案：B) 注意。多储存模型提出，感觉记忆极短暂地持有大量信息。只有我们付出注意的信息才会被传递到短时记忆（STM）。复述是维持信息在STM中并最终将其转入长时记忆（LTM）的过程。提取指将信息从LTM调回STM。精细加工或精细复述是一种更深层次的加工策略，更常与加工水平模型关联。
When answering questions on memory models, always distinguish clearly between the multi-store model (Atkinson & Shiffrin, 1968) and the working memory model (Baddeley & Hitch, 1974). The multi-store model emphasises structural stores and the sequential flow of information, while the working memory model focuses on active processing in the central executive, phonological loop, visuospatial sketchpad and episodic buffer. Reference to the exact studies, such as the serial position effect studies by Glanzer and Cunitz, strengthens answers.
在回答记忆模型相关题目时，务必清晰区分多储存模型（Atkinson & Shiffrin, 1968）与工作记忆模型（Baddeley & Hitch, 1974）。多储存模型强调结构化的储存库和信息有序流动，而工作记忆模型侧重于中央执行系统、语音环路、视空间画板和情景缓冲器中的主动加工。引用确切研究，如Glanzer和Cunitz的系列位置效应实验，能增强答案说服力。
4. Question 3: Short-Answer – Types of Conformity | 题目3：简答题——从众的类型
Define compliance and internalisation in the context of social influence. Use an example for each. (4 marks)
在社会影响的语境中，定义顺从和内化，并为每种类型各举一例。（4分）
Model answer: Compliance refers to a superficial change in behaviour expressed publicly to fit in with a group or authority, while the individual's private beliefs remain unchanged. For example, a student laughs at a joke they do not find funny because everyone else in the group is laughing. Internalisation is a deep-seated change both in public behaviour and private beliefs, as the individual genuinely adopts the group’s viewpoint. For example, a person becomes a vegetarian after joining a friend group that advocates plant-based diets because they now truly believe it is ethical.
参考答案：顺从指个体在公开场合改变行为以迎合群体或权威，但私下信念并未改变的表面变化。例如，一名学生因为组内其他人都在笑而跟着笑一个自己并不觉得好笑的笑话。内化则是公开行为与私下信念均发生深层改变，个体真正接纳了群体的观点。例如，某人加入倡导植物性饮食的朋友圈后自己也成为素食者，因为他们现在真心认为这是符合伦理的。
Note the mark allocation: 1 mark for each accurate definition and 1 mark for each appropriate example. A common mistake is to give an example that describes identification (wanting to be like the group) rather than true internalisation. Always link the example directly to the definition — for compliance, highlight the public-private discrepancy; for internalisation, show that the change persists even without the group present. Referencing Kelman's (1958) three levels of conformity can add depth but is not required at IGCSE level for a full-mark answer.
请注意分值分配：每个准确定义得1分，每个恰当例子得1分。常见错误是给出的例子描述了认同（希望变成群体那样）而非真正的内化。例子务必直接关联定义——对于顺从，要突出公开与私下行为的差异；对于内化，则要表明即使群体不在场，改变依然持续。引用Kelman（1958）的从众三层次理论可增加深度，但在IGCSE层次拿满分并非必需。
5. Question 4: Attachment – Ainsworth's Strange Situation | 题目4：依恋——Ainsworth的陌生情境法
MCQ: 'Which attachment type identified by Ainsworth is characterised by the infant being highly distressed at separation, yet resistant to comfort upon reunion?' A) Secure B) Insecure-avoidant C) Insecure-resistant D) Disorganised
选择题：“Ainsworth识别的哪种依恋类型，其典型表现为婴儿在分离时极度痛苦，重聚时却又抗拒安慰？”A) 安全型 B) 不安全-回避型 C) 不安全-抗拒型 D) 紊乱型
Correct answer: C) Insecure-resistant. In Ainsworth's Strange Situation, insecure-resistant (also called Type C) infants show intense distress when the caregiver leaves. On reunion, they display ambivalent behaviour — they seek closeness but may also resist contact, such as pushing the caregiver away or arching away while crying. Secure (Type B) infants are upset at separation but easily comforted on reunion. Insecure-avoidant (Type A) infants show little distress at separation and actively avoid the caregiver on reunion. Disorganised attachment (Type D) was added later by Main and Solomon and is characterised by contradictory behaviours like freezing or rocking.
正确答案：C) 不安全-抗拒型。在Ainsworth的陌生情境法中，不安全-抗拒型（亦称C类）婴儿在照料者离开时表现出强烈痛苦。重聚时，他们呈现出矛盾行为——既寻求亲近，又可能抗拒接触，例如推开照料者或哭着拱起背。安全型（B类）婴儿在分离时不安，但重聚时易于安慰。不安全-回避型（A类）婴儿在分离时几乎不痛苦，重聚时主动回避照料者。紊乱型依恋（D类）由Main和Solomon后来补充，特征为自相矛盾的行为，如僵住或摇晃。
When asked to describe the Strange Situation procedure, ensure you mention the eight standardised episodes, each lasting around 3 minutes, involving a separation and reunion with the caregiver, and the introduction of a stranger. Also note that the classification is based primarily on the reunion behaviours. Remember to link Ainsworth's work to the concept of the internal working model and later studies like Hazan and Shaver's on adult romantic attachment to show broader application.
当被要求描述陌生情境法程序时，务必提及八个标准化片段，每段约持续3分钟，包含与照料者的分离与重聚，以及引入陌生人。还需注意，类型的划分主要基于重聚时的行为。记得将Ainsworth的研究与内部工作模型的概念联系起来，并联系Hazan和Shaver关于成人爱情依恋的后续研究，以展示更广泛的应用。
6. Question 5: Ethical Considerations in a Hypothetical Study | 题目5：假设研究中的伦理考量
Scenario: A researcher wants to study children's reactions to peer pressure. She plans to use a confederate (stooge) to encourage children to cheat on a spelling test. Identify two ethical issues and explain how they could be addressed. (4 marks)
情境：一位研究者想研究儿童对同伴压力的反应。她计划利用一名同谋（假被试）鼓励儿童在拼写测试中作弊。请指出两个伦理问题并说明如何加以解决。（4分）
Model answer: One ethical issue is deception. The children are not aware that the confederate is part of the study and that cheating is being encouraged for research purposes. This violates the principle of informed consent. The researcher could address this by debriefing the children fully after the study, explaining the true purpose and why deception was necessary. If children are old enough, consent should be obtained from parents as well. A second ethical issue is potential psychological harm. Encouraging children to cheat could cause guilt, anxiety or confusion about right and wrong. The researcher could address this by ensuring that the cheating task is mild and by providing supportive debriefing that clarifies the behaviour was part of the experiment and not a reflection of the child’s character. The researcher should also offer the right to withdraw data and provide counselling if any distress occurs.
参考答案：一个伦理问题是欺骗。儿童不知道同谋是研究的一部分，且作弊是出于研究目的被鼓励的，这违背了知情同意的原则。研究者可通过研究结束后对儿童进行充分的事后解释来解决，说明真正目的及为何需要欺骗。若儿童年龄足够大，还应征得家长同意。第二个伦理问题是潜在心理伤害。鼓励儿童作弊可能引发内疚、焦虑或对是非的困惑。研究者可通过确保作弊任务温和，并提供支持性事后解释来澄清该行为是实验的一部分、不代表孩子的品格。研究者还应提供退出数据的权利，并在出现任何痛苦时提供辅导。
At IGCSE level, always aim to identify issues beyond the obvious 'consent' and 'harm'. For each issue, state the problem clearly, link it to the specific scenario, and propose a concrete, practical solution. Avoid vague statements like 'be ethical' — instead say 'gain written consent from parents and verbal assent from children', or 'use a debrief script to explain the confederate's role'. This shows application of ethical guidelines from the British Psychological Society or equivalent.
在IGCSE层次，需要力争识别出超出明显“同意”和“伤害”之外的问题。对每个问题，清晰陈述难题，与具体情境联系起来，并提出具体、可行的解决方案。避免“要合乎伦理”这样的笼统说法——而是说“获得家长书面同意和儿童口头赞成”，或“使用事后解释稿说明同谋的角色”。这展示了对英国心理学会或类似伦理准则的应用。
7. Question 6: Data Analysis – Interpreting a Bar Chart | 题目6：数据分析——解读柱状图
The bar chart below shows the mean number of words correctly recalled from a list by two groups: Group A used elaborative rehearsal, Group B used maintenance rehearsal. Describe the result and suggest a conclusion. (3 marks)
下方柱状图展示了A组（使用精细复述）与B组（使用保持复述）从词表中正确回忆的单词平均数。请描述结果并推断结论。（3分）
Without an actual image, we assume the bar for Group A is substantially higher than Group B. Model answer: The bar chart shows that Group A (elaborative rehearsal) recalled a higher mean number of words (approximately 18) compared to Group B (maintenance rehearsal) which recalled around 10 words. This suggests that elaborative rehearsal, which involves processing the meaning of the words, is a more effective strategy for transferring information into long-term memory than maintenance rehearsal, which relies on simple repetition. This finding supports the levels of processing theory proposed by Craik and Lockhart, which argues that deeper semantic processing leads to more durable memory traces.
在缺乏实际图片的情况下，我们假设A组的条形显著高于B组。参考答案：柱状图显示，A组（精细复述）正确回忆的平均单词数（大约18个）高于B组（保持复述）的约10个。这表明精细复述涉及加工单词的意义，相较于依赖简单重复的保持复述，是将信息转入长时记忆的更有效策略。该发现支持Craik和Lockhart提出的加工水平理论，即更深层的语义加工引致更持久的记忆痕迹。
In data interpretation questions, always do three things: (1) describe the pattern using figures (higher/lower, means, percentages) without making unsupported claims, (2) draw a precise conclusion linked to the aim or theory, and (3) reference a relevant psychological study or theory if the question implies it. Avoid the common mistake of saying 'Group A remembered better because they tried harder'; instead base the explanation on cognitive processes like depth of processing or use of retrieval cues.
在数据解释题中，务必完成三件事：(1) 使用数据描述模式（更高/更低、均值、百分比），不做无依据的断言；(2) 联系研究目的或理论得出确切的结论；(3) 若题目隐含要求，引用相关的心理学研究或理论。避免常见错误，比如“A组记得更好因为他们更努力”；而应基于认知过程如加工深度或提取线索的利用进行解释。
8. Question 7: Extended Response – Evaluating Asch's Conformity Study | 题目7：拓展回答——评价Asch的从众研究
Evaluate one study of conformity in terms of its methodology and ethics. (8 marks)
从方法与伦理两个角度评价一项从众研究。（8分）
Model answer focusing on Asch (1951): Asch’s line-judgement study used a laboratory experiment with 123 male American college students. Participants were placed in groups with 6–8 confederates who unanimously gave wrong answers on 12 of the 18 critical trials. Asch found that about 75% of participants conformed at least once, and the overall conformity rate was 32% on critical trials. Methodologically, the study had high internal validity due to standardised procedures and controlled setting, allowing a clear cause-and-effect conclusion that group pressure increases conformity. However, the sample was androcentric and culturally biased (all male American students), limiting generalisability. The task was also artificial, meaning the ecological validity is low — people do not usually judge line lengths in real life social pressure situations. Ethically, deception was used: participants believed they were taking a vision test. This violates informed consent. However, Asch debriefed participants afterwards, which addressed the ethical issue retroactively. There was also psychological harm potential, as participants may have felt embarrassed or stressed when realising they conformed against their own judgement. These ethical costs were partially mitigated by the right to withdraw and the educational value of understanding social pressure. Overall, while the study is highly influential, its methodological limitations and ethical concerns mean that the findings need to be considered alongside cross-cultural replications like those by Bond and Smith.
以Asch（1951）为例的参考答案：Asch的线段判断研究采用实验室实验法，被试为123名美国男大学生。被试与6至8名同谋同组，同谋在18次关键测试中有12次一致给出错误答案。Asch发现约75%的被试至少有过一次从众，关键测试中的整体从众率为32%。从方法上看，该研究因标准化程序和受控环境而具有高内部效度，可得出明确的因果结论：群体压力增加从众。然而，样本为男性中心且存在文化偏见（全为美国男生），限制了普遍性。任务也具人工性，意味着生态效度低——人们在现实社会压力情境中通常不判断线段长度。伦理方面，该研究使用了欺骗：被试以为参加的是视力测试，这违背了知情同意。但Asch随后进行了事后解释，追溯性地解决了该伦理问题。被试在意识到自己违背个人判断而从众时，还可能感到尴尬或压力，存在潜在心理伤害。这些伦理代价因退出权和理解社会压力的教育价值而得到部分缓解。总体而言，虽然该研究影响深远，其方法局限与伦理关切意味着研究发现需要结合Bond和Smith等跨文化重复实验来考量。
To achieve top marks (7–8 marks), the evaluation must be balanced, with clear PEEL paragraphs covering methodology and ethics. Use specific terminology: internal validity, ecological validity, generalisability, standardisation, deception, right to withdraw. Make sure to always link back to the question — 'this matters because...'. For example, after stating Asch used deception, explain why that is a problem (lack of informed consent) and what was done about it (debriefing). Avoid merely describing the study; description should be brief and serve the evaluation.
要获得最高分（7-8分），评价必须平衡，并有清晰的PEEL段落涵盖方法与伦理。应使用专业术语：内部效度、生态效度、普遍性、标准化、欺骗、退出权。务必始终回扣题目——“这一点重要在于……”。例如，在陈述Asch使用了欺骗后，解释为何这是个问题（缺乏知情同意）以及采取了什么措施（事后解释）。避免仅仅描述研究；描述应简洁且服务于评价。
9. Question 8: Application to Real Life | 题目8：实际应用
Explain how understanding the multi-store model of memory could help a student revise more effectively. (4 marks)
解释理解记忆的多储存模型如何帮助学生更有效地复习。（4分）
fore, a student should use maintenance rehearsal (repeatedly reviewing notes) to keep information in STM long enough for encoding. More importantly, elaborative rehearsal — linking new information to existing knowledge or creating meaningful associations — se chunking to group individual facts into larger meaningful units, such as turning a list of separate psychological studies into a timeline or thematic categories. Finally, the serial position effect indicates that we remember items at the beginning and end of a study session better. Therefore, a student should structure revision into shorter sessions with regular breaks, ensuring more 'beginnings' and 'endings' and avoiding the primacy and recency effects from being wasted on a single long session.
参考答案：多储存模型指出信息通过复述从STM进入LTM。因此，学生可利用保持复述（反复浏览笔记）使信息在STM保留足够久以利于编码。更重要的是，精细复述——将新信息与已有知识联系起来或创造有意义关联——可加强向LTM的迁移。该模型也强调STM的容量有限（7±2个组块）。学生可使用组块化将单个事实组合成更大的意义单元，例如把一系列零散的心理学研究整理成时间线或主题类别。最后，系列位置效应表明，我们更容易记住学习时段开头和结尾的内容。因此，学生应将复习组织为多个较短时段并规律休息，确保有更多“开头”和“结尾”，避免将首因和近因效应浪费在单一长时段上。
ry to practice. Each piece of advice should be explicitly linked to a feature of the model — never give generic study tips like 'take breaks' gy → resulting cognitive benefit. That is a 3-link chain that ticks every mark scheme box.
应用类题型考验你将理论转化为实践的能力。每条建议都应明确联系模型的一个特征——绝不要给出“要休息”这样的泛泛学习建议，而不解释为何它与多储存模型相关。使用如下链条：模型特征 → 实用策略 → 由此产生的认知收益。这个三环链条正好击中评分标准的所有要点。
10. Common Mistakes and How to Avoid Them | 常见错误与避错指南
1. Confusing operationalisation with control. Students often say 'operationalise the variable' without specifying how. Operationalisation means stating exactly how the IV and DV will be manipulated or measured — e.g., 'the DV will be the number of words correctly recalled from a list of 20' rather than 'memory will be measured'. Be precise.
1. 混淆操作化与控制。学生常说“对变量进行操作化”却不具体说明如何操作。操作化意味着准确陈述IV如何被操纵、DV如何被测量——例如，“DV为从一份包含20个单词的列表中正确回忆的单词数量”，而非“测量记忆力”。务必精确。
2. Describing a study when the question asks for evaluation. In extended responses, limit description to a couple of sentences; the bulk of your answer should evaluate methodology, ethics, validity, reliability and applications. Use trigger words like 'however', 'on the other hand', 'this is because'.
2. 当题目要求评价时却去描述研究。在拓展回答中，描述仅限寥寥数语；答案主体应是评价方法、伦理、效度、信度和应用。使用“然而”“另一方面”“这是因为”这类触发词。
3. Not using psychological terminology. Terms like 'internal working model', 'informational social influence', 'normative social influence', 'retrieval failure', 'capacity', 'duration' and 'encoding' must appear in your answers where relevant. Missing key terms makes it hard for the examiner to award the highest marks.
3. 未使用心理学术语。诸如“内部工作模型”“信息性社会影响”“规范性社会影响”“提取失败”“容量”“持续时间”和“编码”等术语必须在相关答案中出现。缺少关键术语会让考官难以给出最高分。
4. Ignoring ethics. Even if a question does not explicitly ask for ethics, mentioning relevant ethical strengths or limitations of the study you are discussing can add depth and demonstrate synoptic thinking. This is especially useful in the 8-mark evaluation.
4. 忽视伦理。即使题目未明确要求伦理考量，提及所讨论研究的相关伦理优势或不足，可增加深度并展现综合性思维，这在8分评价题中尤其有用。
11. Model Answers Summary with Examiner Comments | 参考答案总结与考官点评
| Question Type 题型 | Key Requirements 关键要求 | Examiner Tips 考官提示 |
|---|---|---|
| MCQ | Know definitions precisely; eliminate distractors. | Read all options before choosing; watch for absolute words like 'always'. |
| Short-Answer (2-4 marks) | Give focused definitions, examples, or applications directly linked to the scenario. | Make each point a new sentence; label parts if question has multiple commands. |
| Data Interpretation | Describe the data, draw a conclusion, refer to theory. | Use numbers from the graph; don't just say 'it increased'. |
| Extended Response (8 marks) | Balanced evaluation using PEEL; must cover methodology and ethics as specified. | Spend 12-15 minutes; plan with a quick mind map listing strengths and weaknesses. |
The table above synthesises what examiners look for. In every answer, aim to 'show off' your knowledge of studies but always in service of the question. A mark scheme targets specific points; if the question asks for an example of internalisation, do not write a whole paragraph about compliance — however accurate it may be, it will not earn marks.
上表综合了考官们的关注点。在每一份答案中，要力争“展示”你对研究的了解，但永远要服务于所提问题。评分方案瞄准具体得分点；若题目要求举一个内化的例子，不要对顺从进行整段论述——无论多准确，都拿不到分。
12. Final Revision Checklist | 最终复习清单
Before your unit test, ensure you can confidently do the following: define all the key terms from the syllabus glossary (memory, attachment, conformity, research methods); outline the procedures and findings of at least three core studies per topic (e.g., Ainsworth's Strange Situation, Asch's line study, Baddeley's word lists); explain the ethical guidelines and apply them to novel scenarios; and write a structured, balanced evaluation using the PEEL format (Point, Evidence/Example, Explanation, Link). Practice with timed conditions, as time management is crucial. Finally, check that you are using the correct psychological vocabulary throughout your answers.
在单元测试前，确保你能自信地做到以下几点：定义大纲词汇表中的所有关键术语（记忆、依恋、从众、研究方法）；概括每个主题至少三项核心研究的程序和发现（如Ainsworth的陌生情境法、Asch的线段研究、Baddeley的词表实验）；解释伦理准则并将其应用于新颖情境；以及使用PEEL格式（观点、证据/示例、解释、回扣）撰写结构化的均衡评价。用限时模拟练习，因为时间管理至关重要。最后，检查你的答案全程使用正确的心理学术语。
