2. Question 1: The First Stage of Memory | 第1题：记忆的第一阶段
Question: What is the first stage of memory according to the multi-store model?
A) Long-term memory B) Sensory memory C) Short-term memory D) Working memory
The correct answer is B) Sensory memory. In the multi-store model proposed by Atkinson and Shiffrin, information from the environment first enters sensory memory, where it is held very briefly in its original form. Only if we pay attention to it does the information move to short-term memory. Options A and C are later stages, and Option D (working memory) is part of a different model, not the first stage.
正确答案是 B) 感觉记忆。在 Atkinson 和 Shiffrin 提出的多储存模型中，来自环境的信息首先进入感觉记忆，并以原始形式短暂保持。只有当我们对其加以注意时，信息才会进入短时记忆。选项 A 和 C 是后续阶段，选项 D（工作记忆）属于另一种模型，并非第一阶段。
3. Question 2: The Capacity of Short-term Memory | 第2题：短时记忆的容量
Question: How many items can most people hold in short-term memory?
A) 3 ± 1 B) 5 ± 2 C) 7 ± 2 D) 9 ± 2
The correct answer is C) 7 ± 2. George Miller’s classic research (1956) found that the average person can hold between 5 and 9 chunks of information in short-term memory, often summarised as ‘the magical number seven, plus or minus two’. This capacity can be increased through chunking, where individual items are grouped into meaningful larger units. Options A and D over- or underestimate the typical range, and Option B is not supported by Miller’s findings.
正确答案是 C) 7 ± 2。George Miller 的经典研究（1956 年）发现，普通人可以在短时记忆中保持 5 至 9 个信息组块，通常归纳为“神奇的数字 7，加 2 或减 2”。通过组块化（将单个项目组合成有意义的较大单元），可以增加这一容量。选项 A 和 D 高估或低估了典型范围，选项 B 则未被 Miller 的研究支持。
4. Question 3: Unlimited Capacity Store | 第3题：无限容量的储存
Question: Which type of memory has unlimited capacity and duration?
A) Sensory memory B) Short-term memory C) Long-term memory D) Iconic memory
The correct answer is C) Long-term memory. According to the multi-store model, long-term memory has a virtually unlimited capacity and can hold information for a lifetime. Sensory memory is very brief, short-term memory has limited capacity and duration, and iconic memory is simply a type of sensory memory for visual information, so it is also fleeting. Understanding the distinct features of each store is fundamental to the Memory unit.
正确答案是 C) 长时记忆。根据多储存模型，长时记忆具有几乎无限的容量，可以存储信息长达一生之久。感觉记忆极为短暂，短时记忆的容量和持续时间都有限，而图像记忆仅是视觉信息的感觉记忆，因此同样转瞬即逝。理解每个储存库的独特特征是记忆单元的基础。
5. Question 4: Proactive Interference | 第4题：前摄干扰
Question: When old information makes it hard to remember new information, this is called:
A) Retroactive interference B) Proactive interference C) Decay D) Displacement
The correct answer is B) Proactive interference. Proactive interference occurs when previously learned material disrupts the recall of newer material. For example, when you have trouble remembering your new phone number because your old one keeps popping into your head. The opposite – when new learning impairs old memories – is retroactive interference. Decay refers to fading over time, and displacement is when new information pushes old information out of short-term memory.
正确答案是 B) 前摄干扰。前摄干扰是指先前学过的材料干扰对新材料的回忆。例如，你难以记住新电话号码，因为旧号码总是浮现。相反的情况——新学习干扰旧记忆——叫倒摄干扰。衰退是指随时间流逝而消退，而取代是指新信息把旧信息从短时记忆中挤出去。
6. Question 5: Retrieval Practice | 第5题：提取练习
Question: Which of the following is an example of retrieval practice?
A) Rereading notes B) Testing yourself with flashcards C) Highlighting text D) Listening to music while studying
The correct answer is B) Testing yourself with flashcards. Retrieval practice involves actively recalling information from memory, which strengthens memory traces. Using flashcards, taking practice quizzes, or writing down everything you remember about a topic are all effective retrieval-based strategies. Rereading and highlighting are passive techniques that do not engage retrieval to the same depth, and listening to music is not a memory strategy in itself.
正确答案是 B) 用卡片测试自己。提取练习是指主动从记忆中回忆信息，从而加强记忆痕迹。使用抽认卡、做模拟测验或写下你关于某个主题的全部记忆，都是高效的提取式学习策略。重读和划重点属于被动技巧，无法同样深度地调动提取过程，而听音乐本身并非记忆策略。
7. Question 6: Describing the Multi-Store Model | 第6题：描述多储存模型
Question: Briefly describe the multi-store model of memory. (4 marks)
A strong 4-mark answer should name the three stores and explain how information moves between them. For example: ‘The multi-store model proposes that memory consists of three separate stores: sensory memory, short-term memory, and long-term memory. Information enters sensory memory from the environment. If we pay attention to it, it transfers to short-term memory. Through rehearsal, information can then be encoded into long-term memory for permanent storage. If rehearsal does not occur, information is likely to be forgotten.’ You can also mention that the model is linear and that each store differs in capacity, duration, and coding.
一个高质量的 4 分答案应当说出三个储存库，并解释信息如何在它们之间流转。例如：“多储存模型提出记忆由三个独立的储存库组成：感觉记忆、短时记忆和长时记忆。信息从环境进入感觉记忆。如果我们对其加以注意，信息就会转入短时记忆。通过复述，信息可以被编码进入长时记忆进行永久储存。如果不进行复述，信息很可能被遗忘。”你也可以提到该模型是线性的，并且每个储存库在容量、持续时间和编码方式上各不相同。
8. Question 7: Explaining Forgetting | 第7题：解释遗忘
Question: Explain one reason why we forget information. (2 marks)
One acceptable explanation is interference theory, where forgetting happens because similar memories compete with each other. For instance, you might forget your new timetable because your old timetable keeps interfering. Another explanation is decay: if information is not rehearsed, the memory trace fades over time. You need to clearly name a reason, briefly explain it, and give a simple example to secure both marks.
一个可接受的解释是干扰理论：遗忘是因为相似的记忆彼此竞争。例如，你可能会忘记新课表，因为旧课表不断产生干扰。另一个解释是衰退：如果不进行复述，记忆痕迹会随时间消褪。你必须明确说出一个原因，简要解释并给出简单例子，才能拿到两分。
9. Question 8: Memory Improvement Strategies | 第8题：改善记忆的策略
Question: Suggest two strategies a student could use to improve their memory for an exam. (4 marks)
Strategy 1: Spaced repetition – spreading revision sessions over several days or weeks instead of cramming the night before. This strengthens long-term retention. Strategy 2: Chunking – grouping small pieces of information into larger, meaningful units, such as remembering a phone number in segments of three or four digits. For each strategy, simply naming it is not enough; you must describe it and say why it works to achieve full marks.
策略 1：分散复习——将复习时段分散在数天或数周内，而不是考前一晚突击。这能强化长时记忆的保持。策略 2：组块化——将小块信息组合成较大的、有意义的单元，比如将电话号码分成三位或四位一组来记忆。每个策略仅说出名称是不够的；你必须加以描述并说明为何有效，才能得到满分。
10. Key Takeaways from the Mock Paper | 模拟卷关键要点
After reviewing this mock paper, remember to focus on precise definitions of the three memory stores and their features. Pay attention to the direction of interference effects – proactive vs. retroactive – as these are common sources of confusion. For the short-answer questions, always provide a ‘what and why’: state your point, explain it, and use an example to show understanding. Using study strategies like retrieval practice and spaced repetition while revising will also directly improve your own memory for the real test.
复习完这份模拟卷后，要记住重点关注三个记忆储存库的精确定义及其特征。注意干扰效应的方向——前摄干扰和倒摄干扰——这是常见的混淆点。对于简答题，务必提供“是什么和为什么”：说出观点，解释观点，并用例子展示理解。在复习时运用提取练习和分散复习等学习策略，也能直接提升你在真正考试中的记忆表现。
11. Common Mistakes to Avoid | 常见错误提醒
Students often lose marks by confusing sensory memory with short-term memory, or by stating that short-term memory lasts for minutes rather than about 18-30 seconds without rehearsal. Another pitfall is mixing up proactive and retroactive interference: always check whether the old material is disrupting the new (proactive) or the new disrupting the old (retroactive). In short-answer responses, simply listing bullet points without clear sentences can limit your marks because the explanation is not fully developed.
学生经常因为混淆感觉记忆与短时记忆，或者错误地认为短时记忆持续数分钟（而非在未经复述的情况下约 18-30 秒）而丢分。另一个易错点是混淆前摄干扰与倒摄干扰：始终要检查是旧材料干扰新材料（前摄），还是新材料干扰旧材料（倒摄）。在简答题中，单纯列出要点而没有完整的句子，会因解释不充分而限制得分。
12. Final Preparation Tips | 考前准备建议
In the final hours before your test, review the multi-store model diagram and test yourself on the capacity and duration of each store. Try writing down one full answer to a describe question under timed conditions. Stay calm, read each question twice, and in multiple-choice questions eliminate obviously wrong options first. Remember, psychology is about linking concepts to real-life examples – your own experiences make excellent evidence.
在考前的最后几小时，复习多储存模型图并自测每个储存库的容量和持续时间。尝试在计时条件下写下一道描述题的完整答案。保持冷静，每题读两遍，做选择题时先排除明显错误的选项。记住，心理学讲究将概念与生活实例相联系——你自身的经历就是很好的证据。
