1. Overview of the Unit Test | 单元测试概览
The Year 8 Edexcel Psychology unit test is designed to assess foundational knowledge acquired during the term. The paper is typically structured into four sections: multiple-choice questions, short-answer questions, scenario-based applications, and a research methods task. The total mark is usually 40, and you have 45 minutes to complete it. Topics covered include the multi-store model of memory, explanations of forgetting, social influence (especially conformity), and experimental design.
爱德思八年级心理学单元测试旨在评估你在本学期掌握的基础知识。试卷通常分为四个部分：选择题、简答题、情景应用题和研究方法任务。总分一般为40分，考试时间为45分钟。所覆盖的主题包括记忆的多重储存模型、遗忘的解释、社会影响（尤其从众）以及实验设计。
2. Key Concept: The Multi-store Model of Memory | 关键概念：记忆的多重储存模型
erm memory (STM), and long-term memory (LTM). Information flows in a linear fashion: sensory input → sensory memory → attention → STM → rehearsal → LTM. Each store differs in terms of capacity, duration, and encoding.
记忆的多重储存模型由阿特金森和希夫林于1968年提出。它描述了三个独立的记忆储存库：感觉记忆、短时记忆（STM）和长时记忆（LTM）。信息以线性方式流动：感觉输入 → 感觉记忆 → 注意 → 短时记忆 → 复述 → 长时记忆。每个储存库在容量、持续时间和编码方式上均有所不同。
| Store | Capacity | Duration | Encoding |
|---|---|---|---|
| Sensory Memory | Very large | Up to 0.5 seconds (iconic), 2–3 seconds (echoic) | Modality-specific (visual, auditory, etc.) |
| Short-term Memory | 7 ± 2 items | 18–30 seconds | Mainly acoustic |
| Long-term Memory | Unlimited | Up to a lifetime | Mainly semantic |
The table above summarises the key features of each memory store. Sensory memory holds raw sensory data, but only information that we pay attention to passes into STM. STM has limited capacity, and maintenance rehearsal is required to keep information there. With elaborate rehearsal, information can be transferred into LTM, where it is stored permanently.
上表总结了每个记忆储存库的关键特征。感觉记忆保存原始的感官数据，但只有我们注意到的信息才会进入短时记忆。短时记忆容量有限，需要通过维持性复述来保持信息。通过精细复述，信息可以转入长时记忆并永久储存。
3. Sample Question 1: Identifying Memory Stores | 样题一：识别记忆储存
Question: 'Sally glanced at a poster while walking past it quickly. Later she could remember the image only if she focused on it for a moment. According to the multi-store model, which memory store was holding the image before she paid attention?'
题目：'Sally 快速路过一张海报时瞥了一眼。后来她发现只有当她盯着看了一小会儿之后才能记住那幅图像。根据多重储存模型，在她注意之前，是哪个记忆储存库保持着这幅图像？'
The correct answer is sensory memory. The icon in Sally's visual sensory memory lasted for less than half a second. Without attention, it decayed almost instantly. This demonstrates the very brief duration characteristic of the sensory register.
正确答案是感觉记忆。Sally 视觉感觉记忆中的图像只持续了不到半秒钟。如果没有注意，它几乎立即就消失了。这恰好体现了感觉寄存器持续时间极其短暂的特征。
4. Key Concept: Factors Affecting Memory Retrieval | 关键概念：影响记忆提取的因素
Forgetting can occur because of retrieval failure or interference. The interference theory suggests that forgetting happens when similar memories disrupt one another. There are two types: proactive interference (old memories interfere with new learning) and retroactive interference (new memories disrupt the recall of old information). Context-dependent cues and state-dependent cues also play a role – you recall better when you are in the same environment or emotional state as when you encoded the information.
遗忘可能源于提取失败或干扰。干扰理论认为，当相似的记忆互相扰乱时就会发生遗忘。干扰分为两种类型：前摄干扰（旧记忆干扰新学习）和倒摄干扰（新记忆干扰对旧信息的回忆）。情境线索和状态线索也发挥着作用——当你处于与编码信息时相同的环境或情绪状态时，回忆效果会更好。
5. Sample Question 2: Interference in Forgetting | 样题二：遗忘中的干扰
Question: 'After learning her new Spanish vocabulary, Fatima found it difficult to recall the French words she had learned the previous month. Which type of interference does this illustrate? Explain your answer.'
题目：'Fatima 在学习新的西班牙语词汇后，发现自己很难回忆起上个月学过的法语单词。这说明了哪种干扰？请解释你的答案。'
This is an example of retroactive interference. The newly learned Spanish material (the new memory) disrupted the recall of the older French material. In proactive interference, the old memory would disrupt the new learning, but here the sequence is reversed: new affects old, hence retroactive.
这是一个倒摄干扰的例子。新学习的西班牙语材料（新记忆）干扰了对更早的法语材料的回忆。在前摄干扰中，是旧记忆干扰新学习，但这里顺序相反：新影响旧，因此是倒摄干扰。
6. Key Concept: Conformity and Asch's Study | 关键概念：从众与阿希实验
Conformity is a type of social influence where an individual changes their behaviour or beliefs to fit in with a group. Solomon Asch (1951) conducted a classic conformity experiment. Participants were asked to judge line lengths in a group where all other members were confederates who deliberately gave wrong answers. About 37% of responses were conforming, and 75% of participants conformed at least once. Two main reasons explain conformity: normative social influence (desire to be liked and accepted) and informational social influence (belief that the group knows better).
从众是一种社会影响，个体改变自己的行为或信念以融入群体。所罗门·阿希（1951年）进行了一项经典的从众实验。被试被要求在一群人中判断线段长度，而群体中的所有其他成员都是故意给出错误答案的假被试。大约37%的回答是从众的，75%的被试至少从众过一次。解释从众主要有两个原因：规范性社会影响（渴望被喜欢和接纳）和信息性社会影响（相信群体更了解情况）。
7. Sample Question 3: Explaining Conformity | 样题三：解释从众行为
Question: 'Tom agreed with his friends that a boring film was actually entertaining because he didn't want to be the odd one out. Identify the type of social influence in this scenario.'
题目：'Tom 赞同朋友们说一部无聊的电影其实很有趣，因为他不想成为格格不入的人。请识别该情景中的社会影响类型。'
This is normative social influence. Tom changed his opinion publicly to avoid rejection and gain social approval, not because he genuinely believed the film was good. He was driven by the need to belong to the group.
这是规范性社会影响。Tom 公开改变自己的观点是为了避免被排斥并获得社会认可，而不是因为他真的认为电影好。他的驱动力是归属群体的需要。
8. Research Methods: Variables and Hypothesis | 研究方法：变量与假设
In psychological research, an experiment involves an independent variable (IV) – the factor that is manipulated or changed by the researcher, and a dependent variable (DV) – the factor that is measured. All other variables should be controlled. A hypothesis is a testable statement predicting the relationship between the IV and DV. For example: 'Students who listen to music while studying will score lower on a memory test than students who study in silence.'
在心理学研究中，实验包含自变量（IV）——研究者操纵或改变的因素，以及因变量（DV）——被测量的因素。所有其他变量应加以控制。假设是一个可检验的陈述，预测自变量与因变量之间的关系。例如：“边听音乐边学习的学生，其记忆测试得分将低于在安静环境中学习的学生。”
9. Sample Question 4: Identifying Independent and Dependent Variables | 样题四：识别自变量与因变量
Question: 'A researcher wants to test whether drinking water improves concentration. Group A drinks 500 ml of water before a puzzle task, while Group B drinks nothing. The time taken to complete the puzzle is recorded. Identify the IV and DV.'
题目：'一位研究者想测试喝水是否能提高注意力。A 组在完成拼图任务前饮用500毫升水，B 组则什么都不喝。记录完成拼图所需的时间。请识别自变量和因变量。'
The independent variable is the amount of water consumed (water vs. no water). The dependent variable is the time taken to complete the puzzle. The researcher manipulates water intake and measures the time, thus the IV is the volume of water and the DV is completion time.
自变量是饮水量（喝水与不喝水）。因变量是完成拼图所需的时间。研究者操纵的是饮水情况，测量的是时间，因此自变量是饮水量，因变量是完成时间。
10. Common Mistakes and How to Avoid Them | 常见错误及避免方法
Many students lose marks by confusing the duration of sensory memory and short-term memory. Always remember: sensory memory lasts less than a second; STM lasts under 30 seconds unless rehearsed. Another common error is mixing up conformity with obedience – conformity involves group pressure without a direct command, while obedience follows a direct order from an authority figure. In research methods, students often reverse the IV and DV. To check, ask yourself 'What am I changing?' (IV) and 'What am I measuring?' (DV).
许多学生因混淆感觉记忆和短时记忆的持续时间而失分。务必记住：感觉记忆持续时间不足一秒；短时记忆若不复述则保持不超过30秒。另一个常见错误是将从众与服从混为一谈——从众涉及群体压力而无直接指令，而服从则是对权威人物直接命令的遵从。在研究方法中，学生常常颠倒自变量和因变量。检查时可以问自己：“我在改变什么？”（自变量）和“我在测量什么？”（因变量）。
11. Exam Tips and Revision Strategies | 考试技巧与复习策略
When revising, create flashcards for key terms such as sensory memory, normative social influence, and interference. Practice writing short definitions in your own words. Use the 'command word' guide: for 'identify' questions, simply name the concept; for 'explain' questions, provide a brief reason or mechanism. Always link your answers to specific studies, like Asch (1951), and use the correct psychological terminology.
复习时，制作关键术语的抽认卡，如“感觉记忆”、“规范性社会影响”、“干扰”。练习用自己的话写出简短的定义。使用“指令词”指南：遇到“识别”类问题，只需说出概念名称；遇到“解释”类问题，则要给出简要的理由或机制。始终将答案与具体研究（如阿希1951年实验）相联系，并使用正确的心理学术语。
