欢迎来到这份针对 Year 9 AQA 心理学的终极复习指南。在本文中，我们将分解最高频的考点，并指出学生常犯的典型错误，帮助你避开它们。尽早理解这些概念，将为你学好 GCSE 心理学甚至更高阶内容打下扎实基础。

1. Mastering Variables and Hypotheses | 掌握变量与假设

In any experiment, the independent variable (IV) is what the researcher changes or manipulates, while the dependent variable (DV) is what is measured. A frequent error is confusing the two; for example, when investigating whether noise affects memory, noise is the IV and memory performance is the DV.

在任何实验中，自变量 (IV) 是指研究者改变或操纵的因素，而因变量 (DV) 则是被测量的结果。一个常见错误就是把两者混淆；例如，在探究噪音是否影响记忆时，噪音是自变量，记忆表现是因变量。

When writing a hypothesis, it must be operationalised – that is, both the IV and DV must be stated in clear, measurable terms. A weak hypothesis such as ‘people will do worse’ becomes testable when written as ‘participants in the loud noise condition will recall fewer words from a list of 20 than those in the silent condition’.

在撰写假设时，必须将其操作化——即自变量和因变量都必须用清晰、可测量的方式陈述。像“人们会做得更差”这种模糊的假设，如果改成“嘈杂条件下的参与者回忆出的20个词表中的单词数将少于安静条件下的参与者”，就变得可检验了。

2. Ethical Considerations in Research | 研究中的伦理考虑

AQA examiners love to ask about ethical issues. Key principles include informed consent, right to withdraw, protection from harm, confidentiality and debriefing. Many students lose marks by only naming an ethical issue without explaining how it applies in the scenario.

AQA 考官喜欢问伦理问题。基本原则包括知情同意、随时退出的权利、免受伤害、保密和事后解释。许多学生丢分是因为只说出伦理问题的名称，却没有解释在情境中如何应用。

A common pitfall is suggesting that ‘anonymity’ can be achieved simply by not using names, but researchers must also avoid reporting data that could identify a participant (e.g. a unique combination of age and school name). Always link your point to the specific study.

一个常见的陷阱是认为只要不用名字就能做到“匿名”，但研究者还必须避免报告可能识别出参与者的数据（例如年龄与学校名称的独特组合）。一定要将论点与具体研究联系起来。

3. The Multi-Store Model of Memory | 记忆的多储存模型

Atkinson and Shiffrin’s model describes three stores: sensory register, short-term memory (STM) and long-term memory (LTM). Information moves from sensory register to STM via attention, and from STM to LTM through rehearsal. Without rehearsal, information is lost through displacement or decay.

Atkinson 和 Shiffrin 的模型描述了三种储存：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，又通过复述从短时记忆进入长时记忆。如果没有复述，信息会因替代或消退而丢失。

Many students confuse the coding, capacity and duration of each store. For example, STM is coded acoustically, has a capacity of 5–9 items, and a duration of about 18–30 seconds. LTM is coded semantically, with potentially unlimited capacity and duration. A typical mistake is stating STM lasts several minutes, or that LTM is coded visually.

许多学生混淆了各储存的编码、容量和保持时长。例如，短时记忆由声音编码，容量为 5–9 个项目，时长约 18–30 秒。长时记忆以语义编码，容量和时长可能无限。一个典型错误是说短时记忆能维持几分钟，或长时记忆是视觉编码。
