📚 Year 11 Cambridge Psychology: Memory Unit Mock Paper Analysis | 剑桥Year 11心理学：记忆单元测试模拟卷解析
This article provides a detailed walkthrough of a mock unit test for the Memory topic in the Cambridge Year 11 Psychology course. Each question is analysed, with model answers and examiner insights to help you master content and exam technique.
本文详细解析了剑桥Year 11心理学课程中“记忆”单元的模拟测试卷。每道题都进行了分析，包含参考答案和考官见解，以帮助你掌握内容和考试技巧。
1. Command Terms and Mark Allocation | 指令词与分数分配
Understanding command terms such as 'describe,' 'explain,' and 'evaluate' is essential for scoring well. 'Describe' requires a detailed account; 'explain' expects reasons or mechanisms; 'evaluate' demands both strengths and weaknesses, often with a judgement. Marks are allocated based on the depth and accuracy of the psychological knowledge shown, not on the length of the response.
理解指令词如“describe”“explain”和“evaluate”对于获得高分至关重要。“describe”要求详细叙述；“explain”需要说明原因或机制；“evaluate”需要既谈优点也说缺点，并通常给出判断。分数的分配取决于所展示的心理学知识的深度与准确度，而非回答的长度。
In Cambridge IGCSE Psychology, a 2‑mark question often tests one piece of knowledge with a brief explanation, while a 6‑mark question typically requires a point, evidence, and an evaluative comment. Always read the command term and the mark allocation to decide how much to write.
在剑桥IGCSE心理学中，一道2分的题目通常考察一个知识点并进行简单解释，而一道6分的题目通常需要提出观点、证据和评价性评论。一定要仔细阅读指令词和分数分配，以此决定回答的篇幅。
2. Question 1: Describe the Multi‑store Model (4 marks) | 第一题：描述多储存模型（4分）
ain full marks, candidates must outline the three separate stores: sensory register, short‑term memory (STM), and long‑ ehearsal. Mentioning that STM has a limited capacity (7 ± 2 items) and duration (around 18–30 seconds), while LTM is potentially unlimited, will secure top marks.
要想获得满分，考生必须概述三个独立的储存器：感觉登记、短时记忆（STM）和长时记忆（LTM）。信息通过注意从感觉登记进入短时记忆，并通过复述从短时记忆转移到长时记忆。提到STM的容量有限（7±2个项目）和持续时间短（约18–30秒），而LTM的容量和持续时间实际上是无限的，有助于拿到高分。
Model answer structure: (1) Name the sensory register and the role of attention; (2) Describe STM as a temporary store with small capacity and acoustic coding; (3) Explain that rehearsal transfers information to LTM; (4) Note that LTM holds information semantically and has a vast capacity. This sequence mirrors the linear flow proposed by Atkinson & Shiffrin.
参考答案结构：(1) 说出感觉登记并说明注意的作用；(2) 将短时记忆描述为一个容量小、以听觉编码为主的临时储存器；(3) 解释复述能将信息转移到长时记忆；(4) 指出长时记忆以语义方式储存信息，容量巨大。这一顺序呈现了Atkinson & Shiffrin提出的线性流程。
3. Question 2: Difference between STM and LTM (2 marks) | 第二题：短时与长时记忆之区别（2分）
One key difference is coding: STM primarily uses acoustic coding, whereas LTM relies on semantic coding. For example, when trying to remember a phone number, you might repeat it aloud (acoustic), but the meaning of a story is stored in LTM. This distinction is supported by Baddeley's 1966 study on word lists.
一个关键区别是编码方式：短时记忆主要使用听觉编码，而长时记忆依赖语义编码。例如，记一个电话号码时你可能反复出声重复（听觉），但对于一个故事的意义则会储存在长时记忆中。这一差异得到Baddeley 1966年词表研究的支持。
s 7 ± 2 chunks, whereas LTM is virtually unlimited. Candidates should avoid simply stating 'one is short, one is long' without reference to psychological research or technical terms, as this would not merit the marks.
另一个有效的区别是容量：短时记忆能容纳7±2个组块，而长时记忆几乎是无限的。考生应避免仅说“一个短，一个长”而不提及心理学研究或专业术语，因为这样将无法得分。
4. Question 3: Central Executive of Working Memory (2 marks) | 第三题：工作记忆的中央执行器（2分）
The central executive is the supervisory component of Baddeley & Hitch's working memory model. It directs attention, allocates data to the phonological loop and visuospatial sketchpad, and coordinates cognitive tasks. It does not store information itself but acts as a controller.
中央执行器是Baddeley & Hitch工作记忆模型中的监督成分。它引导注意、将数据分配给语音回路和视空间画板，并协调认知任务。它本身不储存信息，而是充当控制器的角色。
For 2 marks, a candidate should state that it manages the two slave systems and is responsible for decision‑making and problem‑solving within working memory. Linking it to a real‑life example, such as mental arithmetic while ignoring distractions, can strengthen the answer.
要拿到2分，考生应当说明它管理两个从属系统，并负责工作记忆中的决策和问题解决。如果能联系实际例子，例如进行心算时忽略干扰，可以使答案更充实。
5. Question 4: Proactive vs Retroactive Interference (4 marks) | 第四题：前瞻干扰与回溯干扰（4分）
Proactive interference occurs when old learning disrupts the recall of new information. For instance, having learned French vocabulary earlier can interfere with remembering Spanish words learned later. Retroactive interference is the opposite: new learning impairs the retrieval of old memories, such as a new phone number making it harder to recall the old one.
前瞻干扰是指旧的学习内容干扰了新信息的回忆。例如，先学习的法语词汇可能会干扰后来学习的西班牙语单词的回忆。回溯干扰则相反：新学习的内容损害对旧记忆的提取，比如新电话号码使你更难回忆起旧号码。
A full‑mark answer must clearly define both terms and give an appropriate example for each. Stating that both are explanations for forgetting in long‑term memory, and that they are strongest when the two sets of material are similar, can further demonstrate depth.
满分答案必须清楚界定两个术语并分别为每个术语提供恰当的例子。若能进一步说明两者都是长时记忆中遗忘的解释，并且当两组学习材料相似时干扰最强，则能更显深度。
6. Question 5: Context‑dependent Forgetting (3 marks) | 第五题：背景依赖性遗忘（3分）
The scenario describes context‑dependent forgetting, a retrieval failure explanation. The student's original learning context (classroom) matches the test context, which should improve recall compared to testing in a different environment. This is because the environmental cues present during learning become encoded alongside the material.
该情境描述的是背景依赖性遗忘，一种提取失败的解释。学生的学习原背景（教室）与测试背景相匹配，因此与在不同环境中测试相比，回忆效果应当更好。这是因为学习时存在的环境线索与学习材料一起被编码。
For 3 marks: Identify 'context‑dependent forgetting' or 'retrieval cue failure' (1 mark), explain that matching cues improve recall (1 mark), and link to a study, e.g., Godden & Baddeley's deep‑sea diver study where learning and recall were best in the same environment (1 mark).
3分的分配：识别“背景依赖性遗忘”或“提取线索失败”（1分），解释匹配的线索能改善回忆（1分），并联系一项研究，例如Godden和Baddeley的深海潜水员研究，该研究表明当学习与回忆环境相同时效果最佳（1分）。
7. Question 6: Misleading Information Study (4 marks) | 第六题：错误信息研究（4分）
One well‑known study is Loftus & Palmer (1974). In their experiment, participants watched films of car accidents. They were then asked ‘About how fast were the cars going when they … each other?’ The verb was changed across groups: ‘smashed’, ‘collided’, ‘bumped’, ‘hit’, or ‘contacted’. The estimated speed was significantly higher for the ‘smashed’ group (40.8 mph) than for the ‘contacted’ group (31.8 mph).
一项著名的研究是Loftus和Palmer（1974）的实验。参与者观看车祸影片后，被问及“当汽车……时，它们大约开得有多快？”动词在不同组别中分别被替换为“撞毁”“碰撞”“撞了一下”“撞上”或“接触”。“撞毁”组的估计速度（40.8 mph）显著高于“接触”组（31.8 mph）。
The study shows that the phrasing of a question (misleading information) can distort memory, which has real‑world implications for eyewitness testimony. To gain 4 marks, the answer must describe the aim, procedure, findings, and a brief conclusion about the reconstructive nature of memory.
该研究表明问题的措辞（错误信息）能够扭曲记忆，这对现实中的目击者证词有重要意义。要拿到4分，答案必须描述研究的目的、程序、发现，并对记忆的重构性得出简要结论。
8. Question 7: Strengths and Weaknesses of the Multi‑store Model (6 marks) | 第七题：多储存模型的优缺点（6分）
One strength is that the model was pioneering in showing separate memory stores with distinct properties, supported by cases like HM who had impaired LTM but intact STM. However, a weakness is that it over‑simplifies STM as a single, passive store. The working memory model, with its multiple components, better explains how we can simultaneously process visual and verbal information.
一个优点是该模型开创性地展示了具有不同特性的独立记忆储存器，并得到如HM案例的支持：HM的长时记忆受损而短时记忆完好。然而，一个缺点是它过度简化了短时记忆，将其视为一个单一被动的储存器。相比之下，工作记忆模型包含多个成分，更好地解释了我们如何能同时处理视觉和言语信息。
For a 6‑mark evaluate question, structure matters: start with the strength, give evidence (e.g., clinical cases, brain scans), then move to the weakness, also with evidence. Always include a brief judgement – for instance, stating that while the model has been updated, it remains a useful framework for introducing memory systems.
对于6分的评价题，回答结构很关键：先说优点并给出证据（如临床病例、脑部扫描），然后谈缺点，同样附上证据。务必包含一个简短的评判——比如指出虽然该模型已被更新，但它仍然是介绍记忆系统的一个有用框架。
9. Question 8: Evaluate Laboratory Experiments to Study Memory (6 marks) | 第八题：评估实验室实验研究记忆（6分）
A strong advantage is the high degree of control over extraneous variables, allowing researchers to establish cause‑and‑effect relationships. For example, in Baddeley's coding study, word lists were standardised, and lists were presented in the same way to all participants. This means the findings are reliable and replicable.
一个显著优势是对外来变量的高度控制，使研究者能够建立因果关系。例如，在Baddeley的编码研究中，词表被标准化，并以相同方式呈现给所有参与者。这意味着研究结果是可靠且可重复的。
However, laboratory experiments often lack ecological validity. The artificial learning of word lists does not reflect how memory works in everyday life, where we remember meaningful events. This can limit the generalisability of findings to real‑life situations. Candidates should balance these arguments to score top marks.
然而，实验室实验常常缺乏生态效度。在人工情境下学习词表并不能反映日常生活中记忆的运作方式，在日常生活中我们记住的是有意义的事件。这会限制研究结果推广到真实情境中的能力。考生需要权衡这些论点以获得高分。
10. Question 9: Sensory Memory Study – Sperling (3 marks) | 第九题：感觉记忆研究——斯珀林（3分）
Sperling (1960) studied the duration and capacity of the iconic sensory register. He flashed a grid of 12 letters for 50 milliseconds and asked participants to recall as many as possible. In the whole‑report condition, they could recall about 4–5 letters, but in the partial‑report condition, cued by a tone after the display disappeared, they recalled nearly 3 out of the 4 letters in the cued row, suggesting the iconic memory held most of the image briefly.
Sperling（1960）研究了图像感觉登记的持续时间和容量。他向参与者闪现一个12个字母的网格，持续50毫秒，并要求他们尽可能多地回忆。在全报告条件下，他们能回忆出4–5个字母，但在部分报告条件下，根据显示消失后给出的声音提示，他们几乎能回忆出所提示行4个字母中的3个，这表明图像记忆曾短暂地保存了大部分图像。
For the 3‑mark question, students should describe the procedure, key finding (sensory memory has a large capacity but decays very quickly), and name Sperling. Linking to the multi‑store model's sensory register further demonstrates understanding.
对于这道3分题，学生应当描述程序、关键发现（感觉记忆容量大但消退非常快），并说出Sperling的名字。将其联系到多储存模型中的感觉登记，能进一步展示理解水平。
11. Common Pitfalls and Final Tips | 常见错误与最后建议
Many students lose marks by failing to link answers back to the question. Always use the wording of the question in your opening sentence. Another frequent mistake is describing a study without explaining its relevance - simply narrating the procedure is not enough; you must show how it illustrates a concept or theory.
许多学生因未将答案与问题挂钩而失分。你始终要在开头句中使用问题的措辞。另一个常见错误是描述研究却不解释其相关性——仅仅叙述程序是不够的；你必须说明它如何阐明一个概念或理论。
For evaluation questions, avoid one‑sided answers. Prepare at least one strength and one weakness per topic with supporting evidence. Remember to use psychological terminology accurately: terms like 'ecological validity,' 'demand characteristics,' and 'standardised procedures' will raise the quality of your response.
对于评价题，切忌只谈一面。每个主题至少准备一个优点和一个缺点，并附上支持证据。记住要准确使用心理学术语，例如“生态效度”“需求特征”和“标准化程序”将提升你回答的质量。
Finally, manage your time wisely: a 4‑mark question should take about 4‑5 minutes, while a 6‑mark question should take no more than 7‑8 minutes. Practising with mock papers like this one is the best way to build confidence and writing speed.
最后，合理分配时间：一道4分的题目大约需要4–5分钟，而一道6分的题目不应超过7–8分钟。像这样用模拟试卷进行练习，是建立信心和提高写作速度的最佳方式。
