2. Section A: Multiple-Choice on Memory Encoding | 选择题：记忆编码

Question 1: Which type of encoding involves converting information into sounds? A) Visual encoding B) Semantic encoding C) Acoustic encoding D) Tactile encoding. The correct answer is C. Acoustic encoding is processing information based on its sound, which is commonly used when we rehearse a phone number in our head. Many students confuse semantic encoding (meaning-based) with acoustic encoding, so focusing on definitions is essential.

题目 1：哪种编码方式涉及将信息转换为声音？A) 视觉编码 B) 语义编码 C) 声学编码 D) 触觉编码。正确答案是 C。声学编码是基于声音处理信息的方式，当我们默记电话号码时常用到。许多学生容易混淆语义编码（基于意义）和声学编码，因此务必关注定义的区别。

Question 2: According to the multi-store model, which store has a very limited capacity of 7±2 items? A) Sensory register B) Short-term memory C) Long-term memory D) Episodic buffer. Answer: B. Short-term memory can hold around 7 chunks of information for about 18-30 seconds without rehearsal. This is a classic exam fact – remember the magic number 7±2.

题目 2：根据多存储模型，哪个存储系统的容量非常有限，约为 7±2 个组块？A) 感觉登记 B) 短时记忆 C) 长时记忆 D) 情景缓冲器。答案：B。短时记忆在无复述时可容纳约 7 个信息组块，持续时间约 18–30 秒。这是经典的考试知识点——记住神奇数字 7±2。

3. Topic Deep Dive: Multi-Store Model of Memory | 核心概念深析：记忆的多重储存模型

A common exam question asks you to label the three main stores in the multi-store model and describe the flow of information. The model, proposed by Atkinson and Shiffrin, consists of the sensory register, short-term memory (STM), and long-term memory (LTM). Information moves from sensory register to STM via attention, and then to LTM through rehearsal. If rehearsal does not occur, the information decays or is displaced. Understanding this linear structure is crucial for scoring full marks in both multiple-choice and short-answer questions.

考试中常见的题目要求你标注多存储模型中的三个主要存储单元，并描述信息流动的过程。该模型由 Atkinson 和 Shiffrin 提出，包括感觉登记、短时记忆和长时记忆。信息通过注意从感觉登记进入短时记忆，再通过复述转入长时记忆。若不复述，信息就会衰退或被替代。理解这种线性结构对于在选择题和简答题中拿满分至关重要。

4. Multiple-Choice: Forgetting and Interference | 选择题：遗忘与干扰

Question 3: When old information disrupts the recall of new learning, this is called: A) Retroactive interference B) Proactive interference C) Decay D) Retrieval failure. Answer: B. Proactive interference occurs when previously learned material hinders new learning. For example, calling your new teacher by your old teacher’s name. Be careful not to mix it up with retroactive interference, which is when new information disrupts older memories.

题目 3：旧信息干扰新知识的回忆，这种现象称为：A) 倒摄干扰 B) 前摄干扰 C) 衰退 D) 提取失败。答案：B。前摄干扰指先前的学习内容阻碍了新知识的学习。例如，你用前任老师的名字称呼新老师。注意不要与倒摄干扰混淆，后者是新信息干扰旧记忆。

Question 4: The Peterson and Peterson (1959) study provided evidence for the duration of short-term memory by using: A) Trigram recall after counting backwards B) Free recall of word lists C) Recognition of nonsense syllables D) Digit span tests. Answer: A. Participants had to recall a three-consonant trigram after a delay filled with counting backwards, preventing rehearsal. The findings showed that STM duration is about 18 seconds without rehearsal. This study is often examined in the context of STM duration and the prevention of rehearsal.

题目 4：Peterson 和 Peterson (1959) 的研究通过下列哪种方式为短时记忆的持续时间提供了证据？A) 倒计数后回忆三字母组 B) 词表自由回忆 C) 无意义音节再认 D) 数字广度测验。答案：A。参与者需在延迟并倒数数字后回忆一个三辅音字母组，从而阻止复述。结果表明，无复述时短时记忆持续时间约为 18 秒。这个研究常结合短时记忆持续时间和阻止复述来考查。

5. Section B: Short-Answer on Research Methods | 简答题：研究方法

An example short-answer question: ‘Explain one strength and one weakness of using laboratory experiments to study memory.’ A model answer: One strength is high control over extraneous variables, which allows researchers to establish cause-and-effect relationships between memory tasks and performance. One weakness is low ecological validity: remembering trigrams in a silent room does not reflect how we use memory in daily life, such as remembering a shopping list. Always structure your answer with a clear point, explanation, and link to the context.

简答题示例：“解释实验室实验用于研究记忆的一个优点和一个缺点。”标准答案：一个优点是能够高度控制无关变量，从而使研究者能够确立记忆任务与表现之间的因果关系。一个缺点是生态效度较低：在静音房间中回忆三字母组并不能反映我们在日常生活中使用记忆的方式，例如记忆购物清单。回答时务必采用清晰的观点、解释并结合情境。

6. Case Study Analysis: Eyewitness Testimony | 案例分析：目击者证词

Section C presents a scenario: a witness saw a car accident and was later asked questions about the speed of the vehicles. You are asked to apply your knowledge of leading questions and the Loftus and Palmer (1974) research. In their study, participants estimated a higher speed when the question used the verb ‘smashed’ compared to ‘contacted’. This demonstrates that memory can be distorted by the wording of a question, which has real-world implications for the reliability of eyewitness testimony in court. Use psychological terminology such as ‘misinformation effect’ and ‘reconstructive memory’ to access top marks.

C 部分给出一个情境：目击者看到了一场车祸，随后被问及车辆的速度。要求你运用诱导性提问和 Loftus 与 Palmer (1974) 研究的知识作答。在他们的研究中，当问题中使用动词“撞碎”时，参与者对速度的估计高于使用“接触”时。这表明记忆可能被问题措辞所扭曲，这对法庭上目击者证词的可靠性具有现实影响。使用“错误信息效应”和“重构记忆”等心理学术语有助于获得高分。

7. Data Interpretation Question | 数据解读题

The mock paper includes a bar chart showing the average recall of words from the beginning (primacy effect) and end (recency effect) of a list, compared to the middle. You need to identify the primacy and recency effects and explain them using the multi-store model. Words at the beginning are rehearsed and transferred to LTM (primacy), while words at the end are still in STM (recency). Words in the middle are displaced. This is a common graph interpretation task that tests your ability to link data to theory.

模拟卷中有一道柱状图题，展示了词表中开头部分（首因效应）和末尾部分（近因效应）的单词平均回忆量，并与中间部分对比。你需要识别出首因和近因效应，并用多存储模型加以解释。开头的词被复述并转入长时记忆（首因效应），末尾的词仍停留在短时记忆中（近因效应），而中间词则被替代。这是一道常见的数据解读题，考查你将数据与理论联系起来的能力。

9. Common Exam Pitfalls | 常见失分点

One common mistake is mixing up retroactive and proactive interference. Remember: ‘pro-‘ means forward, so proactive interference is when older memories go forward and disrupt new ones. Another pitfall is describing the multi-store model without mentioning the role of attention and rehearsal – simply naming the stores is insufficient. Also, in case study questions, students often forget to explicitly link the theory to the scenario, which loses marks for application. Practise writing PEEL paragraphs (Point, Evidence, Explain, Link) to build complete answers.

一个常见错误是混淆倒摄干扰和前摄干扰。记法：“前摄”是向前的影响，即旧记忆向前干扰新记忆。另一个失分点是在描述多存储模型时未提及注意和复述的作用——仅说出存储名称是不够的。此外，在案例题中，学生经常忘记将理论与情境明确联系起来，从而丢掉应用分。练习运用 PEEL 段落结构（观点、证据、解释、联系）来组织完整答案。

10. Revision Strategies for KS3 Psychology | KS3 心理学复习策略

To excel in your unit test, create flashcards for key definitions (e.g., encoding, interference, eyewitness testimony) and draw diagrams of the multi-store model from memory. Practise writing timed responses to past paper questions, especially on research methods and the ethical considerations of memory studies. Discussing the studies with a partner can deepen your understanding of why certain methods were chosen. Finally, always link your answers back to the question – this demonstrates true psychological thinking and will help you achieve the highest grades.

为了在单元测试中脱颖而出，你可以制作关键定义（例如编码、干扰、目击者证词）的闪卡，并凭记忆绘制多存储模型图。练习限时回答往年试卷题目，特别是关于研究方法和记忆研究的伦理考量。与同伴讨论这些研究可以加深你对为何选择特定方法的理解。最后，始终将答案与题目联系起来——这体现了真正的心理学思维，并能帮助你取得最高分数。
