1. Mock Test Structure and Weighting | 模拟卷结构与分值
The mock paper is built around the four core themes of the Cambridge Lower Secondary Psychology curriculum: Memory, Social Influence, Research Methods, and Data Literacy. It usually contains four sections. Section A features 10 multiple-choice questions worth 1 mark each, testing factual recall and key concepts. Section B asks short-answer questions (15 marks), often requiring evaluation of studies or ethical reasoning. Section C presents data-response tasks (10 marks), such as interpreting a graph or table. Section D is an extended writing question (15 marks), where you design a study or write a balanced argument. The total is 50 marks and you have 45 minutes – identical to a typical unit test.
模拟卷围绕剑桥初中心理学课程的四大核心主题设计：记忆、社会影响、研究方法和数据素养。试卷一般包含四个部分。A 部分有 10 道选择题，每题 1 分，考查对事实和关键概念的识记。B 部分为简答题（15 分），经常要求评价研究或进行伦理推理。C 部分为数据回答题（10 分），例如解读图表。D 部分是扩展写作（15 分），要求设计一项研究或写一段辩证分析。全卷满分 50 分，答题时间 45 分钟——与真实单元测试一致。
| Section | Question Type | Marks | Focus |
|---|---|---|---|
| A | Multiple-choice | 10 | All topics |
| B | Short-answer | 15 | Evaluating studies & ethics |
| C | Data-response | 10 | Interpreting graphs & tables |
| D | Extended writing | 15 | Designing research / argument |
2. Multiple-Choice: The Multi-Store Model in Action | 选择题：多存储模型的考查
A typical question reads: “According to the multi-store model, information flows from the sensory register to short-term memory through:” Options: A rehearsal, B retrieval, C attention, D encoding. The correct answer is C – attention. Attention is the filter that selects what enters short-term memory. Rehearsal is responsible for transferring information from short-term memory to long-term memory, not from sensory register to STM. Encoding is the process of converting information into a usable form, but it occurs after attention. This question tests precise knowledge of the model’s sequence.
常见的问题是：“根据多存储模型，信息从感觉登记进入短时记忆需要经过：”选项：A 复述、B 提取、C 注意、D 编码。正确答案是 C——注意。注意是选择信息进入短时记忆的过滤器。复述负责将信息从短时记忆转入长时记忆，而不是从感觉登记到短时记忆。编码是指将信息转化为可用形式的过程，但它发生在注意之后。这道题考查对模型序列的精准掌握。
Another question might ask: “What is the estimated capacity of long-term memory?” The answer is “potentially unlimited.” Many students mistakenly choose 7 ± 2 items because they confuse long-term memory with short-term memory. Always remember: short-term memory capacity is about 7 ± 2 chunks, while long-term memory is considered to have an unlimited capacity and can store information for a lifetime.
另一道题可能问：“长时记忆的容量大约是多少？”答案是“潜在无限”。不少学生误选 7 ± 2 个组块，因为他们混淆了长时记忆与短时记忆。务必记住：短时记忆容量大约是 7 ± 2 个组块，而长时记忆的容量被认为是无限的，能够终生存储信息。
3. Multiple-Choice: Debunking Neuromyths | 选择题：揭穿神经神话
Mock papers love to test whether you can separate psychological facts from popular myths. One question states: “The claim that people are either ‘left-brained’ or ‘right-brained’ is inaccurate because:” The correct choice highlights that brain imaging shows both hemispheres work together for most tasks, even if some functions are lateralised. Another myth-based question asks why the idea that “we only use 10% of our brains” is wrong. The answer points to evidence from PET and fMRI scans, which reveal that all parts of the brain are active at different times, and damage to even small areas often produces significant deficits.
模拟卷喜欢考查你能否区分心理学事实与常见迷思。有个问题是：“‘左脑人’或‘右脑人’的说法不准确是因为：”正确选项指出，脑成像研究表明，即使某些功能存在侧化，大多数任务仍需两个半球协同工作。另一个基于迷思的题目询问为什么“我们只用了10%的大脑”是错误的。答案是来自PET和fMRI扫描的证据：大脑所有部位在不同时间都是活跃的，而且即使损伤很小区域也常常导致严重缺陷。
4. Short-Answer: Evaluating Research Methods | 简答题：评价研究方法
A common 4-mark question: “A psychologist uses a laboratory experiment to investigate the effect of music on recall of a word list. Identify one strength and one limitation of using an experiment in this study.” For full marks, you need to state a clear strength (e.g., high control over extraneous variables such as room noise, allowing a cause-and-effect conclusion between music and recall) and a clear limitation (e.g., the artificial setting may not reflect how people remember information in everyday life, so the study lacks ecological validity). Make sure you link the evaluation directly to the scenario – do not just give generic points.
一道典型的4分题：“一位心理学家用实验室实验研究音乐对单词列表回忆的影响。指出该研究使用实验的一个优点和一个局限。”想要拿到满分，你需要清楚陈述优点（例如，对房间噪音等额外变量的高度控制，能够得出音乐与回忆之间的因果关系）和局限（例如，人为设置可能无法反映人们在日常生活中如何记忆信息，因此研究缺乏生态效度）。务必把评价与给定情境直接关联——不要只给出泛泛的要点。
5. Short-Answer: Ethical Considerations in Context | 简答题：情境中的伦理考量
You might see a question like this: “A researcher observes bystander behaviour in a busy shopping centre without informing shoppers. Explain one ethical issue with this naturalistic observation and suggest how it could be addressed. (3 marks)” The key ethical issue is lack of informed consent, since participants do not know they are being watched. However, because the observation takes place in a public setting where people would not expect privacy, it could be considered acceptable under BPS guidelines if no harm is caused. A suitable way to address the issue is to obtain retrospective consent from identifiable individuals afterwards, or to use only aggregated data that does not identify anyone.
你可能遇到这样的题目：“一位研究者在繁忙购物中心观察旁观者行为，没有事先告知购物者。解释这种自然观察的一个伦理问题，并提出解决办法。（3分）”核心伦理问题是缺乏知情同意，因为参与者不知道自己被观察。然而，由于观察发生在公共场合，人们不会抱有隐私期待，如果没有造成伤害，根据BPS指南可视为可接受。一个合适的解决办法是事后获得可辨认个体的追溯同意，或者只使用不辨认个人身份的汇总数据。
6. Data-Response: Interpreting a Forgetting Curve | 数据分析：解读遗忘曲线
In a data-response item, you are shown a graph plotting the percentage of nonsense syllables recalled against time since learning. The curve drops sharply during the first hour, then the rate of forgetting slows down and eventually plateaus. The first question asks you to “Describe the trend shown in the graph.” (2 marks). You should state both the initial rapid decline and the subsequent levelling off. The follow-up question asks you to “Use your knowledge of memory to explain why forgetting occurs.” (3 marks). Here, you should mention that according to the multi-store model, information in short-term memory decays rapidly unless rehearsed. Interference from new learning can also cause forgetting over time.
在一道数据分析题中，你会看到一幅图，描绘了学习后不同时间点能回忆起的无意义音节百分比。曲线在最初一小时内急剧下降，之后遗忘速度放缓，最终趋于平缓。第一问要求“描述图中所示趋势”（2分）。你应当说明初期的快速下降和随后的平稳化。后续问题要求“运用你的记忆知识解释遗忘为何发生”（3分）。这里你应提到，根据多存储模型，短时记忆中的信息如果不进行复述就会快速衰退。此外，新学习的干扰也会导致随时间推移的遗忘。
7. Data-Response: Conformity Counts and Calculations | 数据分析：从众次数与计算
Another data-response task might present a table from an Asch-style experiment. For example, it shows the number of times a participant conformed to an incorrect majority across 18 critical trials when various numbers of confederates were present. A question could be: “Calculate the percentage conformity when the group contained 3 confederates, given that the participant agreed with the wrong answer in 12 of the 18 trials. Show your working.” (2 marks). The correct calculation is:
(12 ÷ 18) × 100 = 66.7%
Always round to the same number of decimal places as shown in the question or to one decimal place. The mark scheme awards one mark for the correct formula and one for the accurate percentage. This tests both your maths skills and your understanding that conformity increases with group size up to a point.
另一道数据分析题可能给出阿希式实验的表格。例如，显示在不同数量的同谋在场时，被测试者在 18 次关键试验中附和错误多数的次数。可能的问题是：“当组内有3名同谋时，被测试者12次同意错误答案。计算从众百分比并展示计算过程。（2分）”正确计算公式如上。务必按题目所示小数位数或取一位小数进行四舍五入。评分方案中，正确公式得1分，准确百分比得1分。这既考查你的数学技能，也考查你对从众行为随群体规模增大而上升直至某一点的理解。
8. Extended Writing: Designing a Memory Experiment | 扩展写作：设计记忆实验
The 15-mark extended writing question might ask: “Design an experiment to investigate whether handwriting notes leads to better recall than typing notes. Include in your answer: aim, independent and dependent variables, how you would control two extraneous variables, the procedure, and one ethical consideration.” A high-scoring response would specify the aim clearly: to compare recall scores between two groups after studying a text by handwriting or typing. The independent variable is the method of note-taking (handwriting vs typing), and the dependent variable is the number of correctly recalled facts from the text. To control extraneous variables, you could keep the text difficulty constant and use the same quiet room for all participants. The procedure should mention random allocation of participants to conditions, a standardised study time, and a distractor task before recall to prevent rehearsal. Ethically, you must obtain informed consent and allow participants to withdraw their data.
15 分的扩展写作题可能这样要求：“设计一个实验，研究手写笔记是否比打字笔记带来更好的回忆。在你的回答中包括：目的、自变量与因变量、如何控制两个额外变量、实验程序以及一项伦理考量。”高分的回答会清晰地说明目的：比较两组学生在手写或打字学习后回忆得分。自变量是笔记方式（手写 vs 打字），因变量是从文本中正确回忆的事实数量。为控制额外变量，你可以保持文本难度恒定，并为所有参与者使用同一间安静的房间。程序部分应提到将参与者随机分配到不同条件、标准化的学习时间以及在回忆前设置干扰任务以防止复述。伦理上，你必须获得知情同意，并允许参与者撤回数据。
9. Common Mistakes That Cost Marks | 导致失分的常见错误
One frequent mistake is confusing short-term memory (STM) with long-term memory (LTM) when describing capacity and duration. Always keep the multi-store model’s distinct stores separate in your mind. Another error is writing about ethical issues without proposing a remedy: simply stating “there was no informed consent” only gains half the marks. You must always suggest how the issue could be managed, such as by debriefing participants or gaining parental consent for under-16s. In data questions, many students describe a graph but forget to back up their description with figures. Use data points! For example, “Recall dropped from 80% at immediate testing to 30% after 20 minutes.” Finally, in experimental design, failing to operationalise the independent variable (e.g., leaving out whether notes are taken on paper or a tablet) results in a vague answer.
一个常见错误是在描述容量和持续时间时混淆短时记忆与长时记忆。务必在脑海中把多存储模型的不同存储库清晰地区分开。另一个错误是只指出伦理问题却不提供补救措施：仅仅说“没有知情同意”只能拿一半的分。你必须总是提出解决办法，例如在实验后对参与者进行情况说明，或为 16 岁以下参与者取得家长同意。在数据题中，许多学生描述了图形却忘记用数据支撑。要引用数据点！例如，“回忆率从即时测试时的 80% 下降到 20 分钟后的 30%。” 最后，在实验设计中，未能操作化自变量（例如，没说明笔记是用纸笔还是平板电脑来做）会导致答案含混不清。
10. Targeted Revision Strategies | 有策略地进行复习
To prepare thoroughly, create revision cards for each memory model – multi-store model and reconstructive memory – listing key features and supporting studies. For social influence, practise applying Asch’s variables (group size, unanimity, task difficulty) to novel scenarios. When reviewing research methods, focus on how to design a controlled experiment and how to critique studies in terms of validity, reliability, and ethics. Solve plenty of data-handling questions: work with tables, calculate percentages, and use the formula: (number of cases ÷ total) × 100. Finally, time yourself on a full mock paper under exam conditions – then use this walkthrough to mark your own work and identify exactly where you drop marks.
要全面备考，可以为每个记忆模型（多存储模型和重构记忆）制作复习卡片，列出关键特征和支持性研究。对于社会影响，练习将阿希实验的变量（群体大小、一致性、任务难度）应用于新情境。复习研究方法时，重点关注如何设计对照实验，以及如何从效度、信度和伦理角度批判研究。多做数据处理题：练习看表格、计算百分数，并熟练使用公式 (案例数 ÷ 总数) × 100。最后，在模拟考试条件下给自己计时完成一份完整的模拟卷——然后用本解析给自己评分，精准找出失分点。
