1. Mock Paper Overview and Command Words | 模拟卷概览与指令词
This mock paper mirrors a typical Year 10 unit test combining multiple-choice questions, short-answer items, applied scenarios, and a 6-mark evaluation. Understanding the command words is essential: ‘identify’ means to state or name; ‘describe’ requires a detailed account; ‘explain’ asks for reasons or mechanisms; and ‘evaluate’ demands strengths, weaknesses, and a reasoned conclusion.
这份模拟卷还原了一份典型的 Year 10 单元测试，包含选择题、简答题、应用题和一道 6 分的评估题。理解指令词至关重要：“识别”要求陈述或列举；“描述”需要给出详细的说明；“解释”是问原因或机制；而“评估”则要求写出优点、缺点，并给出有依据的结论。
2. Multiple-Choice Questions: Key Terms | 选择题：关键术语
Let’s begin with a terminology question. Which of the following is an example of a dependent variable (DV)? A) Time of day B) Number of words recalled correctly C) Age of participants D) Type of background noise. The correct answer is B, because the DV is the outcome variable being measured — in this case, memory performance. Options A and D are likely independent variables (IV), while C is an extraneous participant variable.
我们从一道术语选择题开始。以下哪一项是因变量（DV）的例子？ A) 一天中的时间 B) 正确回忆的单词数量 C) 参与者的年龄 D) 背景噪音的类型。正确答案是 B，因为因变量是被测量的结果变量——这里是记忆表现。选项 A 和 D 很可能是自变量（IV），而 C 属于额外的参与者变量。
3. Identifying Independent and Dependent Variables | 识别自变量与因变量
A researcher investigates whether listening to music while studying affects test scores. One group revises with music; the other revises in silence. Both groups then take the same 20-question quiz. Identify the independent variable (IV) and the dependent variable (DV). The IV is the presence or absence of music (learning condition), as it is the factor being manipulated. The DV is the test score, because it is the outcome being measured. Always operationalise variables clearly: ‘the number of correct answers on the quiz out of 20’.
一位研究者想探究学习时听音乐是否会影响测验成绩。一组在音乐环境中复习，另一组在安静环境下复习。两组随后完成同样的 20 道题测验。请识别自变量和因变量。自变量是是否有音乐（学习条件），因为这是被操纵的因素。因变量是测验成绩，因为它是被测量的结果。请始终将变量操作化清晰：“测验中答对的题数（满分 20）”。
4. Experimental Designs: Strengths and Weaknesses | 实验设计：优点与缺点
Imagine the music study uses an independent groups design, meaning different participants are in each condition. Describe one strength and one weakness of this design. A key strength is that there are no order effects: participants only complete the task once, so practice or fatigue does not distort results. A weakness is participant variables: individual differences (such as natural memory ability) might influence the scores, making it harder to attribute differences solely to the IV. The matched pairs or repeated measures designs could be discussed as alternatives.
假设上述音乐研究采用了独立组设计，即每组由不同的参与者组成。请描述该设计的一个优点和一个缺点。一个关键优点是无需考虑顺序效应：每位参与者只完成一次任务，因此练习或疲劳不会干扰结果。缺点是存在参与者变量：个体差异（例如天生的记忆力）可能会影响成绩，从而难以将差异完全归因于自变量。还可以讨论匹配对设计或重复测量设计作为替代方案。
5. Ethical Considerations in Research | 研究中的伦理考量
In a memory experiment with Year 7 students, participants were asked to recall embarrassing childhood events without their parents’ knowledge. Explain one ethical issue the researcher should have addressed. The most obvious issue is lack of informed consent: the participants were minors, so consent from parents or guardians was required. Furthermore, the study could cause psychological harm through distress. Researchers should provide a full debrief afterwards and ensure the right to withdraw data at any stage.
在一项针对七年级学生的记忆实验中，参与者被要求回忆尴尬的童年事件，而家长并不知情。请解释研究者本应考虑的一项伦理问题。最明显的问题是缺乏知情同意：参与者是未成年人，因此必须得到父母或监护人的同意。此外，该研究可能引发心理伤害，造成痛苦。研究者应在事后提供完整的情况说明，并确保参与者有权在任何阶段撤回数据。
6. Memory: Multi-Store Model Application | 记忆：多存储模型应用
Describe the multi-store model of memory (MSM) proposed by Atkinson and Shiffrin. (4 marks) The MSM describes three separate stores: the sensory register, which receives all environmental stimuli and holds them for less than half a second; information that is paid attention to passes into the short-term memory (STM), which has a limited capacity of around 7±2 chunks and a duration of about 18–30 seconds; through maintenance rehearsal, information can be transferred to the long-term memory (LTM), which has potentially unlimited capacity and duration. This linear model emphasises rehearsal as the key control process.
请描述 Atkinson 和 Shiffrin 提出的多存储记忆模型（MSM）。（4 分）MSM 描述了三个独立的存储器：感觉登记器接收所有环境刺激并保持不到半秒；被注意到的信息进入短时记忆（STM），其容量有限，约为 7±2 个组块，持续时长约 18–30 秒；通过维持性复述，信息可以转入长时记忆（LTM），其容量和持续时长几乎无限。该线性模型强调复述是核心控制过程。
7. Social Influence: Conformity and Asch | 社会影响：从众与阿希研究
Explain one factor that increases conformity, using Asch’s (1951) line judgement study. In Asch’s experiment, a naive participant was placed in a group of confederates who unanimously gave wrong answers. Conformity rose to about 37% on critical trials. A major factor is group size: Asch found that conformity increased when the majority consisted of three or more people, but plateaued after that. Another factor is unanimity — when just one confederate broke the consensus, conformity dropped sharply. Such findings illustrate normative social influence, where individuals conform to be accepted or avoid rejection.
请结合 Asch（1951）的线条判断实验，解释一个增加从众程度的因素。在 Asch 的实验中，一名真实的参与者被安排在一群事先统一给出错误答案的假同伙中间。关键试次中的从众率约为 37%。一个主要因素是团体规模：Asch 发现，当多数派达到三人或以上时，从众度上升，但之后便趋于平缓。另一个因素是意见一致性——一旦有一位假同伙打破了共识，从众度就急剧下降。这些发现说明了规范性社会影响，即个体为了被接纳或避免被排斥而选择从众。
8. Research Methods: Data Analysis and Descriptive Statistics | 研究方法：数据分析与描述统计
A student replicated a study on context-dependent memory: recalling words in the same room (condition A) versus a different room (condition B). The numbers of words recalled by five participants were: Condition A — 9, 12, 10, 11, 8; Condition B — 7, 8, 6, 9, 5. Calculate the mean recall for each condition. Show your workings.
一名学生重复了一项上下文依赖记忆的研究：在同一房间（条件 A）与不同房间（条件 B）回忆单词。五名参与者回忆的正确单词数分别为：条件 A — 9, 12, 10, 11, 8；条件 B — 7, 8, 6, 9, 5。试计算每个条件的平均回忆量，并写出计算过程。
Mean = Σx / n
For Condition A, sum = 9+12+10+11+8 = 50; n = 5, so mean = 50/5 = 10. For Condition B, sum = 7+8+6+9+5 = 35; mean = 35/5 = 7. Therefore, recall appears higher in the same-room condition. Always round to two decimal places where appropriate. Visualising data through a bar chart would make this comparison clear, with the condition on the x-axis and mean recall on the y-axis.
对于条件 A，总和 = 9+12+10+11+8 = 50；n = 5，因此平均值 = 50/5 = 10。条件 B，总和 = 7+8+6+9+5 = 35；平均值 = 35/5 = 7。可见，相同房间条件下的回忆量更高。在必要时，应四舍五入至两位小数。若用条形图展示数据，可将条件标在 x 轴，平均回忆量标在 y 轴，对比则会更加直观。
9. Evaluation Questions: Building a High-Mark Response | 评估题：构建高分答案
Evaluate the multi-store model of memory. (6 marks) A strong answer follows a ‘PEEL’ structure: Point, Evidence, Explanation, and Link. A point might be: ‘A strength is that the model is supported by case studies such as HM.’ Evidence: ‘HM’s hippocampus was removed, and he could no longer form new long-term memories, yet his STM was intact.’ Explanation: ‘This supports the MSM’s separation of STM and LTM as distinct stores.’ Weaknesses must also be covered, e.g. the model is oversimplified — it does not account for different types of LTM (episodic, semantic, procedural) or explain how elaborative rehearsal leads to durable memories. Conclude by balancing strengths and limitations.
请评估多存储记忆模型。（6 分）一份出色的答案会遵循“PEEL”结构：论点、证据、解释和链接。一个论点可以是：“该模型的优点是得到了如 HM 这类个案研究的支持。”证据：“HM 的海马体被摘除后无法形成新的长时记忆，但他的短时记忆完好无损。”解释：“这支持了 MSM 将短时记忆和长时记忆区分为不同存储器的观点。”此外，还必须论述其缺点，例如模型过于简化——它既未考虑长时记忆的不同类型（情景记忆、语义记忆、程序性记忆），也未解释精细复述如何形成持久的记忆。最后，需在权衡优点和局限性之后给出结论。
10. Common Mistakes and Examiner Advice | 常见错误与考官建议
Many students lose marks by failing to link answers back to the stem question. For example, when asked to ‘explain one ethical issue… and suggest how to deal with it’, do not just list general ethical issues like deception; instead, state how that specific study would deceive and then propose a specific solution, such as gaining retrospective consent after the study. Another common error is confusing the IV and DV, or describing a strength of an experimental design without justifying why it is a strength in that context. Finally, in evaluation questions, always provide both a strength and a weakness, and avoid simply repeating the description of the study.
许多学生因未将答案与题干相联而失分。比如，当题目要求“解释一项伦理问题……并给出应对方法”时，不要只泛泛列出欺骗这类一般性伦理议题；而应说明该具体研究如何存在欺骗，进而提出具体的解决办法，如事后获得回溯性同意。另一个常见错误是混淆自变量和因变量，或者在描述实验设计的优点时未能解释为何它在具体情境中是优点。最后，在评估题中，一定要既写优点又写缺点，避免只是重复研究的描述。
11. Applying Your Knowledge to Unfamiliar Scenarios | 将知识应用于陌生情境
OCR exams frequently present novel scenarios, such as a psychologist testing whether a memory improvement app actually works. You need to recognise that the IV is the use or non-use of the app, while the DV could be the number of items recalled from a list after one week. You might be asked to suggest an experimental design: a repeated measures design could control for participant variables but might create order effects. Always justify your choice based on what is most practical and valid for that particular scenario. Remember to operationalise variables with precision.
OCR 考试常出现全新的情境题，例如一位心理学家测试某款记忆提升 app 是否有效。你需要识别出，自变量是使用或不使用该 app，因变量可能是一周后从列表中回忆出的项目数。你还可能被要求提出一种实验设计：重复测量设计能控制参与者变量，但可能带来顺序效应。永远要基于在特定情境下最实用、最有效这一原则，为你的选择提供依据。切记要精确地将变量操作化。
