2. Q1 – Defining Encoding in the Multi‑store Model | 第1题 – 定义多储存模型中的编码
The question asked: 'Define the term 'encoding' as used in the multi‑store model of memory. (2 marks)'. A full-mark answer specifies that encoding is the process of converting sensory input into a format that the memory system can retain. It is essential to mention that this allows information to pass from the sensory register into short‑term memory, and that encoding can occur in acoustic, visual or semantic forms.
题目要求：“定义多储存记忆模型中‘编码’这个术语。(2分)”。高分答案需明确指出，编码是将感觉输入转化为记忆系统可保存的形式的过程。还须提及编码使信息能够从感觉登记进入短时记忆，并且编码可通过听觉、视觉或语义等形式进行。
Many students lose a mark by omitting a concrete process or by failing to link encoding to a specific store. Remember, in the multi‑store model, encoding is the necessary first step that determines whether a stimulus is even noticed by memory. For example, if you pay attention to a friend’s new phone number, you are acoustically encoding the digits, allowing them to enter your short‑term memory.
许多同学会因为遗漏具体过程或未能将编码与特定储存器联系起来而丢分。记住，在多储存模型中，编码是决定刺激是否被记忆注意到的必要第一步。例如，如果你注意朋友的新的电话号码，你就在对数字进行听觉编码，使它们进入短时记忆。
3. Q2 – Multiple Choice: Duration of Short‑term Memory | 第2题 – 选择题：短时记忆的持续时间
The item read: 'Which of the following best describes the typical duration of short‑term memory? A) 2‑3 seconds B) 18‑30 seconds C) 5‑10 minutes D) Unlimited'. The correct choice is B: 18‑30 seconds. This finding comes from the classic Peterson & Peterson (1959) study, where participants were given a trigram (e.g., CHJ) and then counted backwards to prevent rehearsal.
题目如下：“下列哪项最恰当地描述了短时记忆的典型持续时间？A) 2‑3秒 B) 18‑30秒 C) 5‑10分钟 D) 无限”。正确答案是B：18‑30秒。这一发现源自经典的Peterson & Peterson (1959) 实验，参与者先看到一个三字母组（如CHJ），然后通过倒计数来阻止复述。
After just 3 seconds of counting, recall was about 80%, but after 18 seconds it dropped below 10%. This demonstrated that without active rehearsal, short‑term memory traces decay within roughly 18‑30 seconds. Option A refers to sensory memory duration, and option C and D are incorrect for STM. Always recall key numbers from memory studies to support multiple‑choice answers.
仅计数3秒后，回忆率约为80%，但18秒后便降至10%以下。这证明如果没有主动复述，短时记忆痕迹大约在18‑30秒内衰退。选项A指的是感觉记忆的持续时间，选项C和D对短时记忆而言是错误的。解答选择题时务必回忆记忆研究中的关键数字来支撑判断。
4. Q3 – Short Answer: Sensory Memory Store | 第3题 – 简答题：感觉记忆储存
This question asked: 'Describe two characteristics of the sensory memory store. (2 marks)'. One mark was given for each accurate characteristic. A characteristic describes the huge capacity of the sensory register – it can hold a vast amount of information from all senses, almost a direct copy of the input. However, its duration is extremely brief: iconic (visual) memory lasts about 0.5 seconds, while echoic (auditory) memory may last 2‑3 seconds.
本题要求：“描述感觉记忆储存的两个特征。(2分)”。每准确描述一个特征得1分。感觉登记的一个特征是容量巨大——它能保存来自所有感官的大量信息，几乎是原始输入的直接复制。然而，其持续时间极短：图像（视觉）记忆约持续0.5秒，声像（听觉）记忆可能持续2‑3秒。
Some students mistakenly claim that sensory memory has a small capacity or long duration, confusing it with short‑term memory. To avoid this, link each feature back to Sperling’s (1960) partial report paradigm, which showed that participants could see more than they could report before the iconic image faded. Using study evidence in short answers, even when not explicitly required, shows deeper understanding.
有些同学会错误地声称感觉记忆容量小或持续时间长，将其与短时记忆混淆。为避免此类错误，可将每个特征关联到Sperling (1960) 的部分报告范式，该范式证实参与者在图像记忆消退前能看到比能够报告更多的信息。在简答中引用研究证据，即使题目未明确要求，也能展现更深的理解。
5. Q4 – Application: Eyewitness Testimony and the Multi‑store Model | 第4题 – 应用题：目击证词与多储存模型
The question: 'Explain how information about a crime might be transferred through the memory stores according to the multi‑store model. (4 marks)'. For full credit, the answer needed to identify attention as the process moving information from sensory memory to short‑term memory, and then rehearsal as the process moving information from STM to long‑term memory, applied to a crime scenario.
题目：“根据多储存模型解释犯罪信息是如何通过记忆储存器传递的。(4分)”。要得满分，答案需指出注意是将信息从感觉记忆转移至短时记忆的过程，而复述是将信息从短时记忆转移至长时记忆的过程，并应用到犯罪情境中。
For instance, attention allows the witness to transfer the observation of the perpetrator’s face into STM. Then, maintenance rehearsal – such as mentally repeating the description or discussing it with another witness – strengthens the memory, encoding it into long‑term memory for later retrieval. Failing to explicitly name 'attention' or 'rehearsal' usually causes a loss of marks. Always use the model’s terminology.
例如，注意使目击者将观察到嫌疑人的面孔传入短时记忆。接着，维持性复述——如在脑中重复描述或与其他目击者讨论——强化该记忆，将其编码进入长时记忆，以便日后提取。未能明确说出“注意”或“复述”通常会导致失分。务必使用该模型的术语。
6. Q5 – Identifying Independent and Dependent Variables | 第5题 – 识别自变量和因变量
The question presented a scenario: 'A psychologist investigates whether background music affects memory recall. Participants learn a list of words either with music or in silence. Identify the independent variable (IV) and dependent variable (DV). (2 marks)'. The IV is the condition (music vs. silence), because it is the factor being manipulated by the researcher. The DV is the number of words correctly recalled, as it is the measured outcome.
题目给出一个情境：“一位心理学家研究背景音乐是否影响记忆回忆。参与者分别在音乐条件和安静条件下学习一组单词。指出自变量(IV)和因变量(DV)。(2分)”。自变量是条件（音乐与安静），因为它是研究者操纵的因素。因变量是正确回忆的单词数，因为它是被测量的结果。
A very common mistake is to write 'memory recall' as the DV without specifying how it is measured. To be precise, you must state the operationalised DV: the score on a recall test, for example. Also, be careful not to confuse the IV with extraneous variables such as the type of music or the room temperature; only the deliberately changed factor is the IV.
一个常见的错误是将“记忆回忆”作为因变量而未说明测量方式。为准确起见，必须陈述操作化后的因变量，例如回忆测验的得分。此外，注意不要将自变量与额外变量混淆，如音乐类型或室温；只有故意改变的因素才是自变量。
7. Q6 – Ethics in Psychological Research | 第6题 – 心理学研究中的伦理问题
The question: 'State two ethical guidelines a researcher must follow when conducting a memory study with Year 8 students. (2 marks)'. Acceptable answers included: obtaining informed consent from participants and their parents/guardians; ensuring participants have the right to withdraw at any time; protecting participants from psychological and physical harm; maintaining confidentiality of data; and providing a debrief at the end of the study.
题目：“指出研究者在进行一项涉及八年级学生的记忆研究时必须遵循的两条伦理准则。(2分)”。可接受的答案包括：获得参与者及其家长/监护人的知情同意；确保参与者有权随时退出；保护参与者免受心理和生理伤害；对数据保密；以及研究结束时提供事后解释。
Many students wrote vague terms like 'be ethical' without naming specific guidelines, which scored zero. The OCR mark schemes expect precise phrases: 'protection from harm' and 'informed consent' carry marks. Because participants are under 16, parental consent is a crucial detail. Remember the acronym C‑D‑R‑I‑P (Consent, Deception, Right to withdraw, Informed consent, Protection from harm) to recall key ethical issues.
许多同学写了“要合乎伦理”等模糊表述而没有列出具体准则，这样的作答得零分。OCR评分方案期望使用精确短语：“保护免受伤害”和“知情同意”才能得分。由于参与者未满16岁，家长许可是一个关键细节。记住缩略词C‑D‑R‑I‑P（同意、欺骗、退出权、知情同意、免受伤害）来回忆主要伦理问题。
8. Q7 – Interpreting a Bar Chart of Results | 第7题 –解读结果条形图
Students were shown a bar chart of the background music experiment: the mean recall in the music condition was 10 words, and in the silence condition it was 12 words. The question: 'What conclusion can be drawn from the graph? (2 marks)'. The correct conclusion is that participants recalled more words in silence than with music, suggesting that background music may have a negative effect on verbal memory recall.
题目向学生展示了一个背景音乐实验的条形图：音乐条件下的平均回忆量为10个单词，安静条件下为12个单词。问题：“从图中可以得出什么结论？(2分)”。正确的结论是参与者在安静条件下比在音乐条件下回忆出更多单词，这表明背景音乐可能对言语记忆回忆产生负面影响。
To achieve the second mark, many answers needed to mention that this was only a difference in means and that further analysis or replication would be needed to be sure. Avoid over‑concluding, such as stating 'music always harms memory' – the OCR examiners look for cautious language like 'suggests', 'may', or 'in this study'. This demonstrates critical thinking.
要得到第二个分数，许多答案需要提到这只是平均数的差异，并且需要进一步分析或重复实验才能确定。避免过度下结论，例如声称“音乐总是损害记忆”——OCR考官喜欢看到诸如“表明”、“可能”或“在本研究中”等谨慎措辞。这展现了批判性思维。
9. Q8 – Extended Response: Evaluate the Multi‑store Model | 第8题 – 拓展回答：评价多储存模型
The final question was worth 6 marks: 'Discuss one strength and one weakness of the multi‑store model of memory. (6 marks)'. A strong evaluation requires a clear point, evidence or reasoning, and a link back to the model. For a strength, the model is supported by case studies of amnesia, such as HM and Clive Wearing, who demonstrated separate STM and LTM as the model predicts.
最后一道题占6分：“讨论多储存记忆模型的一个优点和一个缺点。(6分)”。强有力的评价需要一个清晰的观点、证据或推理，并与模型关联。一个优点是该模型得到失忆症个案研究的支持，例如HM和Clive Wearing，他们表现出该模型所预测的分离的短时记忆和长时记忆。
For the weakness, many answers highlighted that the model is too simplistic, portraying memory as a single linear flow. However, Baddeley and Hitch’s working memory model shows that STM has multiple components (phonological loop, visuo‑spatial sketchpad). Furthermore, the MSM overlooks alternative routes to LTM, such as elaborative rehearsal, and does not explain the distinct types of LTM – episodic, semantic and procedural.
至于缺点，许多答案强调该模型过于简单，将记忆描绘成单一的线性流。但Baddeley和Hitch的工作记忆模型表明短时记忆包含多个组件（语音回路、视空间画板）。此外，多储存模型忽视了通往长时记忆的其他途径（如精细复述），也没有解释长时记忆的不同类型——情景、语义和程序性记忆。
For a 6‑mark response, it is also helpful to mention that the model’s reliance on laboratory experiments (e.g., Glanzer & Cunitz serial position effect) gives it scientific credibility, but the tasks can be artificial and lack ecological validity. Balancing your evaluation with both sides of the argument, and using psychological terms accurately, is the key to high marks.
对于6分回答，提及该模型依赖实验室实验（如Glanzer和Cunitz的系列位置效应）使其具有科学可信度，但任务可能过于人为并缺乏生态效度，也会有所帮助。平衡地评价正反两面，并准确使用心理学术语，是取得高分的关键。
10. Key Takeaways and Common Mistakes | 核心要点与常见错误
rstly, students frequently mix up the duration and capacity of the different memory stores – refer to the accepted figures: STM capacity is 7 ± 2 items (Miller, 1956) and duration 18‑30 seconds.
在批阅了大量模拟卷后，几个反复出现的错误尤为突出。首先，同学们经常混淆不同记忆储存器的持续时间和容量——例如，说短时记忆持续几秒但容量无限。务必记住公认数据：短时记忆容量为7 ± 2个项目（Miller, 1956），持续时间为18‑30秒。
Second, in research methods questions, answers often lack operationalisation. When asked to identify a dependent variable, writing 'memory' is insufficient; you must state how memory is measured, e.g., 'the number of words correctly recalled from a list of 20'. Third, evaluation questions are strongest when they contain a counter‑argument. If you write a strength, always balance it with a limitation that uses a named researcher or concept.
其次，在研究方法题中，答案常常缺乏操作化。当被要求指出因变量时，只写“记忆”是不够的；你必须说明记忆如何被测量，如“从20个单词列表中正确回忆出的单词数量”。第三，评价类题目如果包含反方论点，会显得更有力。如果你写了一个优点，一定要用列出的研究者或概念来平衡一个局限性。
Finally, always read the command word carefully. 'Define' means give the precise meaning; 'Explain' requires linking causes and effects; 'Evaluate' demands both strengths and weaknesses. Practising with this mock paper and revising the model answers will give you confidence for the real unit test.
最后，务必仔细阅读指令词。“定义”要求给出精确含义；“解释”要求关联原因与结果；“评价”则要求写出优点和缺点。使用这份模拟卷进行练习，并复习标准答案，将使你从容应对真实的单元测试。
