Understanding the format and the mark allocation is the first step towards success. In this analysis, we will look at sample questions from each section and break down exactly what the examiners are looking for.
了解试卷格式和分值分配是迈向成功的第一步。在本次解析中，我们将逐一查看各部分的样题，并详细拆解考官所期望看到的内容。
2. Section A: Multiple Choice – Hypothesis and Variables | A 部分 选择题 – 假设与变量
Multiple-choice questions often test your ability to recognise definitions and apply basic concepts. Here is a sample question on hypotheses and variables:
选择题通常考查你是否能够识别定义并应用基本概念。以下是一道关于假设和变量的样题：
Sample Question 1: ‘What is meant by a hypothesis in psychological research?’
A) A definitive conclusion about the results
B) A testable statement predicting the relationship between variables
C) An untested assumption about behaviour
D) A summary of all previous research on a topic
Correct answer: B
样题 1：“心理学研究中，假设的含义是什么？”
A) 关于研究结果的确切结论
B) 一个可检验的陈述，预测变量之间的关系
C) 关于行为的一个未经检验的假定
D) 对某一主题所有以往研究的总结
正确答案：B
A hypothesis is a precise, testable statement that predicts how the independent variable will affect the dependent variable. It is not a final conclusion or just an assumption; it must be formulated before the experiment is conducted so that it can be tested against the data.
假设是一个精确、可检验的陈述，它预测自变量将如何影响因变量。它既不是最终结论，也不仅仅是一个假定；它必须在实验进行之前就制定好，以便能够用数据来检验。
Sample Question 2: ‘In an experiment, the variable that the researcher manipulates is known as the:’
A) dependent variable
B) extraneous variable
C) independent variable
D) confounding variable
Correct answer: C – independent variable (IV).
样题 2：“在实验中，研究者操纵的变量被称为什么？”
A) 因变量
B) 无关变量
C) 自变量
D) 混淆变量
正确答案：C – 自变量 (IV)。
The dependent variable (DV) is the factor that is measured, and any change in the DV should be caused by manipulation of the IV. Many students confuse the two, so always ask: which one am I deliberately changing? That is your IV.
因变量 (DV) 是被测量的因素，DV 的任何变化都应当由 IV 的操纵引起。许多学生会混淆这两个概念，因此一定要问自己：我故意改变了哪一个？那就是你的自变量 (IV)。
3. Section A: Multiple Choice – Experimental Designs | A 部分 选择题 – 实验设计
Experimental design is another core area tested early in the paper. Below is a typical question:
实验设计是试卷前面部分另一个常考的核心领域。以下是一道典型题目：
Sample Question 3: ‘A researcher uses two separate groups of participants: one group drinks a caffeinated beverage and the other group drinks a decaffeinated version. Both groups then complete a memory test. This design is an example of:’
A) repeated measures
B) matched pairs
C) independent groups
D) naturalistic observation
Correct answer: C – independent groups design.
样题 3：“一位研究者使用两组不同的被试：一组饮用含咖啡因的饮料，另一组饮用不含咖啡因的版本。然后两组被试都完成一项记忆测试。这种设计属于：”
A) 重复测量设计
B) 匹配对设计
C) 独立组设计
D) 自然观察
正确答案：C – 独立组设计。
In an independent groups design, each participant is allocated to only one condition. This avoids order effects, but participant variables (such as individual differences in memory ability) can influence the results. In repeated measures, the same participants take part in all conditions, which controls for participant variables but may cause order effects.
在独立组设计中，每位被试只被分配到一种实验条件中。这避免了顺序效应，但被试变量（例如记忆力的个体差异）可能会影响结果。而在重复测量设计中，同一批被试参与所有实验条件，这控制了被试变量，但可能会产生顺序效应。
| Design | Key strength | Key weakness |
|---|---|---|
| Independent groups | No order effects | Participant variables may confound results |
| Repeated measures | Controls for participant variables | Order effects (e.g. practice, fatigue) |
| Matched pairs | Reduces participant variables without order effects | Time-consuming and difficult to match perfectly |
The table above summarises the three main experimental designs you need to know. Always be ready to identify a design from a scenario and to explain one advantage and one disadvantage.
上表总结了你需要掌握的三种主要实验设计。要随时准备好从某个情境中识别出一种实验设计，并解释其一个优点和一个缺点。
4. Section A: Multiple Choice – Sampling Methods | A 部分 选择题 – 抽样方法
Sampling methods are frequently tested. Read the following question:
抽样方法是常考内容。请阅读以下题目：
Sample Question 4: ‘A researcher stands in the school cafeteria and selects every fifth student who enters to take part in a study. Which sampling technique is being used?’
A) random sampling
B) opportunity sampling
C) systematic sampling
D) stratified sampling
Correct answer: C – systematic sampling.
样题 4：“一位研究者站在学校食堂，选择每第五个进入的学生参与研究。这里使用了哪种抽样技术？”
A) 随机抽样
B) 机会抽样
C) 系统抽样
D) 分层抽样
正确答案：C – 系统抽样。
Systematic sampling uses a fixed interval (e.g. every 5th person) to select participants from a target population. It is fairly unbiased and straightforward to implement. Opportunity sampling involves simply selecting whoever is available, while random sampling requires that every member of the target population has an equal chance of being chosen.
系统抽样使用固定的间隔（例如每第 5 个人）从目标总体中选择被试。它相对公平且易于实施。机会抽样则是简单选择任何当时可接触的人，而随机抽样要求目标总体中的每一个成员都有均等的机会被选中。
When you evaluate a sampling method, think about representativeness (does the sample reflect the target population?) and practical issues (time, ease). For instance, opportunity sampling is quick but often produces a biased sample.
当你评估某种抽样方法时，要考虑代表性（样本是否能反映目标总体？）和实用性问题（时间、便捷性）。例如，机会抽样快捷，但常常产生有偏差的样本。
5. Section B: Short Answer – Identifying Variables from a Scenario | B 部分 简答题 – 从情景中识别变量
Section B requires you to apply your knowledge to novel scenarios. A common question asks you to identify the IV and DV in a short description.
B 部分要求你将知识应用到新情景中。一个常见的问题是让你在简短描述中识别自变量和因变量。
Sample Question 5: ‘A psychologist wants to test whether background noise affects concentration. She divides 40 participants into two groups: one group works on a puzzle in silence and the other works while loud traffic noise is played. The time taken to complete the puzzle is recorded.’
Identify the independent variable and the dependent variable in this experiment.
样题 5：“一位心理学家想要检验背景噪音是否会影响注意力。她将 40 名被试分成两组：一组在安静环境中完成拼图，另一组在播放嘈杂交通噪音的环境中完成拼图。记录完成拼图所需的时间。”
请识别本实验中的自变量和因变量。
Model answer: The independent variable is the presence or absence of background noise (two conditions: silence vs. traffic noise). The dependent variable is the time taken to complete the puzzle, measured in seconds or minutes.
标准答案：自变量是背景噪音的有无（两种条件：安静 vs 交通噪音）。因变量是完成拼图所需的时间，以秒或分钟为单位测量。
Key tip: Always state the IV in terms of the conditions being manipulated, not just the general concept. And make sure the DV is operationalised – indicating how it will be measured.
关键提示：陈述自变量时一定要以被操纵的条件来表达，而不仅仅是概念本身。同时确保因变量是可操作的——明确说明它将如何被测量。
6. Section B: Short Answer – Ethical Considerations | B 部分 简答题 – 伦理考量
Ethics questions appear regularly because the AQA specification expects you to understand how to conduct research responsibly. Here is a typical short-answer question:
伦理问题经常出现，因为 AQA 大纲期望你理解如何负责任地开展研究。以下是一道典型的简答题：
Sample Question 6: ‘A researcher plans to observe students’ eating habits in the school canteen without their knowledge. Explain one ethical issue that might arise and suggest how the researcher could address it.’
样题 6：“一位研究者计划在食堂暗中观察学生的饮食习惯。解释可能产生的一个伦理问题，并建议研究者可以如何解决。”
Model answer: One ethical issue is the lack of informed consent. Because participants are unaware they are being observed, they cannot agree to take part. The researcher could address this by obtaining retrospective consent: after the observation, the researcher would inform the students about the study and give them the right to withdraw their data if they wish. Alternatively, the researcher could obtain prior general consent from the school authorities and ensure all data is anonymised to protect the students' privacy.
标准答案：一个伦理问题是缺乏知情同意。因为被试不知道自己正在被观察，他们无法同意参与。研究者可以通过获取追溯同意来解决：即在观察结束后，告知学生有关研究的信息，并允许他们可以选择退出数据。或者，研究者可以事先取得学校管理部门的一般性同意，并确保所有数据均匿名化以保护学生隐私。
Remember the key ethical principles from AQA: informed consent, deception, right to withdraw, protection from harm, privacy and confidentiality. Your answer must name a specific issue and offer a realistic solution.
记住 AQA 重点的伦理原则：知情同意、欺骗、退出权、免受伤害、隐私和保密。你的回答必须指出一个具体问题，并提供一个切合实际的解决方案。
7. Section B: Short Answer – Memory Processes | B 部分 简答题 – 记忆过程
Questions on memory often require you to describe features of the multi-store model (MSM). Below is a question that tests your knowledge of the sensory register.
关于记忆的题目经常要求你描述多存储模型 (MSM) 的特征。下面是一道考查你对感觉登记器了解的题目：
Sample Question 7: ‘Outline the duration and capacity of the sensory register. Refer to one type of sensory memory in your answer.’ (3 marks)
样题 7：“概述感觉登记器的持续时间和容量。在你的回答中提及一种感觉记忆类型。”（3 分）
Model answer: The sensory register has a very large capacity because it receives all incoming sensory information. However, its duration is extremely brief – less than one second for visual information (iconic memory) and about 2–3 seconds for auditory information (echoic memory). Information in the sensory register is held in an unprocessed form, and only if attention is paid to it will it be transferred to short-term memory.
标准答案：感觉登记器的容量非常大，因为它会接收所有传入的感觉信息。然而，它的持续时间极为短暂——视觉信息（图像记忆）持续时间不到一秒，听觉信息（余音记忆）大约为 2–3 秒。感觉登记器中的信息以未经加工的形式保存，只有当我们对其加以注意时，信息才会被传递到短时记忆。
When describing the sensory register, always link to the role of attention as the filter to short-term memory. In the multi-store model, attention is crucial because most sensory information decays almost instantly if it is not attended to.
在描述感觉登记器时，一定要提及注意力作为通向短时记忆的过滤作用。在多存储模型中，注意力至关重要，因为如果未被注意，大多数感觉信息几乎会瞬间消退。
8. Section C: Extended Writing – Describe and Evaluate a Memory Model | C 部分 拓展写作 – 描述与评估一种记忆模型
The extended writing question is worth a significant portion of your marks and tests both AO1 (knowledge) and AO3 (evaluation). A classic question is: 'Describe and evaluate the multi-store model of memory.' (12 marks)
拓展写作题在你的总分中占据较大比重，同时考查 AO1（知识）和 AO3（评价）。一个经典问题是：“描述并评价记忆的多存储模型。”（12 分）
To score well, you should structure your response clearly. Start with AO1: describe the three stores (sensory register, short-term memory, long-term memory) in terms of capacity, duration, and coding. Then move to AO3: evaluate the model by supporting research and limitations. For example, you could mention Peterson and Peterson’s study that showed STM duration is about 18–30 seconds without rehearsal, supporting the idea of a separate STM store.
要取得高分，你应该清晰地构建你的回答。从 AO1 开始：从容量、持续时间和编码方面描述三个存储系统（感觉登记器、短时记忆、长时记忆）。然后进入 AO3：通过支持性研究和局限性来评价该模型。例如，你可以提到 Peterson 和 Peterson 的研究表明，在没有复述的情况下，短时记忆的持续时间约为 18–30 秒，这支持了存在独立 STM 存储的构想。
However, be sure to also highlight limitations. The MSM has been criticised for being too simplistic, suggesting that STM and LTM are unitary stores. The working memory model, proposed by Baddeley and Hitch, challenged this by showing that STM has multiple components such as the central executive and phonological loop. Furthermore, cases of brain-damaged patients (such as KF) demonstrated that short-term memory for verbal material can be impaired while visual memory remains intact, contradicting the idea of a single STM store.
然而，一定要同时强调它的局限性。MSM 因过于简单而受到批评，它认为 STM 和 LTM 都是单一的系统。Baddeley 和 Hitch 提出的工作记忆模型对此提出了质疑，指出 STM 包含多个成分，如中央执行器和语音回路。此外，脑损伤患者（例如 KF）的个案表明，对言语材料的短时记忆可能受损，而视觉记忆却保持完好，这与单一 STM 存储的观点相矛盾。
A balanced paragraph evaluating the model might look like this: 'A strength of the MS
