Candidates should expect questions that require precise terminology, application of knowledge to novel scenarios and critical evaluation. The following sections unpack each question type and provide guidance on how to maximise marks.
考生应预料到需要精确使用术语、将知识应用于新情境并进行批判性评估的题目。以下各节将逐一解析每类题型，并指导如何最大化得分。
2. MCQ 1: Identifying the Independent Variable | 选择题1：识别自变量
Question: “A psychologist investigates the effect of background noise on concentration. Participants complete a puzzle in either a silent room or a room with loud traffic noise. The time taken to finish the puzzle is recorded. What is the independent variable (IV)?”
A) Type of puzzle
B) Presence/absence of noise
C) Time taken to complete the puzzle
D) The participants’ age
题目：“一位心理学家研究背景噪音对专注力的影响。被试分别在安静房间或充满交通噪音的房间中完成一项拼图，记录完成拼图所需时间。什么是该实验的自变量？”
A) 拼图类型
B) 有无噪音
C) 完成拼图的时间
D) 被试的年龄
The correct answer is B. The independent variable is the factor manipulated by the researcher. Here, the psychologist deliberately alters the noise condition. Options A and D are extraneous variables that would need controlling, while C is the dependent variable (DV) — the outcome measured. In AS exams, always identify the manipulated condition as the IV and distinguish it clearly from the DV.
正确答案是B。自变量是研究者所操纵的因素。此实验中心理学家特意改变了噪音条件。选项A和D是需要控制的额外变量，而C是因变量(DV)——所测量的结果。在AS考试中，务必识别操纵条件为自变量，并将其与因变量明确区分。
3. MCQ 2: Brain Localisation | 选择题2：大脑功能定位
Question: “A patient has difficulty producing fluent speech after a stroke, though his comprehension remains intact. Which area of the brain is most likely damaged?”
A) Wernicke’s area
B) Broca’s area
C) Hippocampus
D) Motor cortex
题目：“一名患者中风后难以流畅地产生言语，但理解能力完好。哪一脑区最可能受损？”
A) 韦尼克区
B) 布洛卡区
C) 海马体
D) 运动皮层
The answer is B — Broca’s area. This region, located in the left frontal lobe, is responsible for speech production. Damage leads to Broca’s aphasia, characterised by non-fluent, effortful speech. Wernicke’s area (A) involves language comprehension; hippocampal damage affects memory; the motor cortex controls voluntary movements. For AS biological approach questions, be precise about localisation of function and use correct names.
答案是B——布洛卡区。该区位于左额叶，负责言语产出。受损会导致布洛卡失语症，表现为不流利、费力的言语。韦尼克区(A)参与语言理解；海马体损伤影响记忆；运动皮层控制随意运动。回答AS生物取向问题时，需精确说明功能定位并使用正确名称。
4. Short Answer: Multi-Store Model of Memory | 简答题：记忆的多重存储模型
Question: “Briefly describe the multi-store model of memory. (4 marks)”
题目：“简要描述记忆的多重存储模型。(4分)”
To gain full marks, your answer must mention three distinct stores and the processes linking them. The model proposes that information enters sensory memory, where it lasts for a fraction of a second. If attended to, it passes to short-term memory (STM), which has limited capacity (7±2 items) and duration (around 18 seconds). Through maintenance rehearsal, information can be transferred to long-term memory (LTM), which has unlimited capacity and duration. Use the terms ‘sensory register’, ‘short-term memory’, ‘long-term memory’ and ‘rehearsal’ explicitly.
要获得满分，你的回答必须提及三个不同的存储库以及连接它们的过程。该模型提出信息首先进入感觉记忆，在此仅持续几分之一秒。若被注意，则转入短时记忆(STM)，其容量有限(7±2个组块)且持续时间约18秒。通过维持性复述，信息可转入长时记忆(LTM)，其容量和持续时间均无限。务必明确使用’感觉登记’、’短时记忆’、’长时记忆’和’复述’这些术语。
Examiners look for a clear linear description. Avoid evaluating the model here — the command word is ‘describe’. A common error is confusing STM and LTM roles or omitting rehearsal, costing a mark.
考官期望看到清晰的线性描述。这里不要对模型进行评价——指令词是’描述’。常见错误是混淆STM与LTM的作用或遗漏复述，从而失分。
5. Short Answer: Obedience and Agency Theory | 简答题：服从与代理理论
Question: “Explain what is meant by ‘agency theory’ as applied to obedience. (4 marks)”
题目：“解释应用于服从的’代理理论’是什么意思。(4分)”
Milgram’s agency theory proposes that individuals operate in two states: the autonomous state, where they take personal responsibility for their actions, and the agentic state, where they perceive themselves as agents carrying out the orders of an authority figure. Moral strain arises in the agentic state when a person’s actions conflict with their conscience. The shift from autonomous to agentic state explains why ordinary people obey destructive orders. High-scoring responses will also mention that binding factors, such as the legitimacy of the authority, keep the individual in the agentic state.
米尔格拉姆的代理理论提出个体在两种状态下运作：自主状态，此时个人对其行为负责；代理状态，此时他们视自己为执行权威人物命令的代理人。当代理状态中个体的行为与良心冲突时，会产生道德压力。从自主状态向代理状态的转变解释了为何普通人会服从破坏性命令。高分回答还会提及，诸如权威合法性的约束因素使个体维持在代理状态。
6. Essay Question: Evaluate the Behaviourist Approach | 论述题：评价行为主义取向
Question: “Evaluate the behaviourist approach in psychology. (8 marks)”
题目：“评价心理学中的行为主义取向。(8分)”
To structure a balanced essay, devote roughly half to knowledge (AO1) and half to evaluation (AO3). Begin by outlining core assumptions: all behaviour is learned from experience, only observable behaviour should be studied scientifically, and learning occurs through classical and operant conditioning. Mention Pavlov’s dogs and Skinner’s operant chamber as key research. Then provide at least three well-developed evaluation points.
要建构一篇均衡的论述，大约一半篇幅用于知识(AO1)，一半用于评价(AO3)。先概述核心假设：所有行为皆通过经验习得，只有可观察行为才应被科学研究，学习通过经典条件反射和操作条件反射发生。提及巴甫洛夫的狗与斯金纳的操作箱作为关键研究。然后提供至少三个充分的评价点。
A strength is the approach’s scientific rigour — it uses controlled laboratory experiments yielding objective, replicable data. This adds credibility and has enabled practical applications, such as token economies in schools. However, critics argue it is reductionist, ignoring cognitive and biological processes. For instance, Bandura’s social learning theory demonstrates mediational processes. The approach is also environmentally deterministic, suggesting free will is an illusion. Finally, much of the research relies on animal studies, raising issues of generalisability. Remember to link each point directly back to the question.
一个优点在于其科学严谨性——它采用受控实验室实验，产生客观、可重复的数据。这增加了可信度并促成了实际应用，如学校的代币经济。但是，批评者认为它是还原论的，忽视了认知与生物过程。例如，班杜拉的社会学习理论证明了中介过程的存在。该取向也是环境决定论的，暗示自由意志是幻象。此外，许多研究依赖动物被试，引发可推广性问题。记住每个要点都要直接回扣题目。
7. Data Response: Chi-Squared Test | 数据分析题：卡方检验
Scenario: Researchers wanted to see whether gender influences choice of A-level subject category (science or arts). Observed frequencies are shown below:
情境：研究者想探究性别是否影响A-level科目类别(科学或艺术)的选择。观察频数如下表：
| Science | Arts | Total | |
|---|---|---|---|
| Male | 40 | 20 | 60 |
| Female | 30 | 30 | 60 |
| Total | 70 | 50 | 120 |
The expected frequency for each cell is (row total × column total) / grand total. For male science: (60×70)/120 = 35. Applying the formula:
每个单元格的期望频数为(行合计×列合计)/总计。以男性科学为例：(60×70)/120 = 35。应用公式：
χ² = Σ ( (O − E)² / E )
Calculations yield χ² ≈ 3.43. Degrees of freedom (df) = (rows-1) × (columns-1) = 1. Using a critical values table, the critical χ² value at p < 0.05 for df=1 is 3.84. Since our observed value (3.43) is less than the critical value, the result is not significant; we cannot reject the null hypothesis. Always state such a conclusion: there is insufficient evidence of an association between gender and subject choice.
计算得χ² ≈ 3.43。自由度(df) = (行数-1)×(列数-1) = 1。查临界值表，df=1、p<0.05水平下的临界χ²值为3.84。由于观测值(3.43)小于临界值，结果不显著；我们不能拒绝零假设。务必给出这样的结论：没有足够证据表明性别与科目选择之间存在关联。
8. Issues and Debates: Nature vs Nurture | 议题与争论：天性对教养
The nature–nurture debate asks the extent to which behaviour is determined by heredity (nature) or environment and learning (nurture). AS essays often require you to discuss this debate in relation to a specific approach or behaviour. For example, when explaining aggression, the biological approach emphasises the role of the MAOA gene (nature), while the social learning approach highlights observational learning and reinforcement (nurture).
天性–教养之争探讨行为在多大程度上由遗传(天性)或环境与学习(教养)决定。AS论述常要求你结合某一特定取向或行为讨论该争议。比如，在解释攻击行为时，生物取向强调MAOA基因的作用(天性)，而社会学习取向则强调观察学习与强化(教养)。
A strong response shows an interactionist stance: most behaviours arise from an interplay between the two. Bandura’s Bobo doll study, for instance, demonstrates that children learn aggressive scripts through nurture, but biological predispositions may influence how readily a child imitates. Use this debate to add sophistication to your evaluation paragraphs.
高分回答应展现交互论的立场：多数行为源于两者的相互作用。例如，班杜拉的波波玩偶研究表明儿童通过教养习得攻击脚本，但生物易感性可能影响幼儿模仿的倾向。运用此争论为评价段增添深度。
9. Common Mistakes and Examiner Tips | 常见错误与考官建议
Mistake 1: Confusing the independent variable and dependent variable in research methods questions. Always ask: “What is being manipulated?” and “What is being measured?”
错误1：研究方法题中混淆自变量与因变量。始终自问：”操纵的是什么？”以及”测量的是什么？”
Mistake 2: Listing strengths and weaknesses as bullet points without explanation. Each evaluation point must be elaborated — use the PEEL structure (Point, Evidence, Explanation, Link).
错误2：像列清单般列出优缺点而不作解释。每个评价点都需详述——采用PEEL结构(观点、证据、解释、链接)。
Mistake 3: Neglecting operationalisation. In answers, define variables clearly: e.g., ‘memory was operationalised as number of words recalled from a 20-word list’.
错误3：忽略操作性定义。回答中应清晰定义变量：例如，’记忆被操作化为对20词词表中单词的回忆个数’。
Mistake 4: In data analysis, forgetting to state whether the results are significant at a named probability level and what this means for the hypothesis.
错误4：数据分析中，忘记说明结果在某个已标明概率水平上是否显著及其对假设的含义。
10. Conclusion and Revision Strategy | 结论与复习策略
Working through a mock paper under timed conditions is one of the most effective ways to prepare for your unit tests. This analysis has highlighted how examiners apply mark schemes, the importance of command words, and the need for precise terminology. Revisit any topic where you lost marks and practise writing full essay answers to build evaluation skills.
在计时条件下完成模拟卷是准备单元测试最有效的方式之一。本解析已突出考官如何应用评分方案、指令词的重要性以及术语准确性的要求。重访任何失分课题，并练习书写完整的论述答案以建立评价能力。
Regular retrieval practice, such as drawing the multi-store model from memory or explaining agency theory to a peer, will strengthen your long-term retention. Combine these techniques with past paper analysis, and approach your exam with confidence.
定期的提取练习，如默画多重存储模型或向同伴解释代理理论，将增强长期记忆的保持。将这些技巧与真题分析结合，自信地迎接考试。
