在CAIE AS心理学(9990)中写论文是一项可以通过系统训练掌握的技能。无论是作答8分“描述”题，还是12分“描述并评价”题，清晰的框架都能帮助你有条理地组织答案、满足考核目标并拿到高分。本文分解核心写作框架、评价策略，并提供完整的范文供你研读和借鉴。
1. Understanding the CAIE AS Psychology Essay Requirements | 了解CAIE AS心理学论文要求
In the CAIE AS Level Psychology exam, Paper 1 presents essay questions based on the four core approaches: biological, cognitive, learning and social. You will encounter either an 8-mark ‘describe’ question or a 12-mark ‘describe and evaluate’ question for one of the approaches. The 8-mark question tests your knowledge of a core study, while the 12-mark question additionally requires critical evaluation. Both types demand accurate psychological terminology, logical structure and depth of detail.
在CAIE AS心理学考试中，Paper 1基于四大核心取向（生物、认知、学习、社会）会出论文题。你可能会遇到某个取向的8分“描述”题或12分“描述并评价”题。8分题考查你对核心研究的了解，而12分题还要求进行批判性评价。两类题目都要求准确的心理学术语、逻辑结构以及扎实的细节。
2. Decoding Command Words and Mark Allocation | 解读指令词与分值分布
‘Describe’ means you must give a detailed account of a study or theory. In an 8-mark essay, marks are typically split into four level-descriptor bands, rewarding accuracy of the aim, procedure, results and conclusion. For a 12-mark essay, the 12 marks are divided equally: up to 6 marks for AO1 (description) and up to 6 marks for AO3 (evaluation). ‘Evaluate’ requires you to weigh strengths and weaknesses, support your points with evidence and link to wider issues such as ethics, validity, generalisability and application.
“Describe”（描述）意味着必须对研究或理论作详细说明。在8分论文中，分数通常分布在四个等级描述中，奖励对目的、过程、结果和结论的准确性。在12分论文中，分数对半分：最多6分给AO1（描述），最多6分给AO3（评价）。“Evaluate”（评价）要求你权衡优点和缺点，用证据支撑论点，并联系伦理、效度、普遍性、应用等更广泛议题。
3. The PEEL Paragraph Structure | PEEL段落结构
To write coherent paragraphs, use the PEEL model: Point – state the evaluation point or descriptive detail. Evidence – cite specific details from the study (e.g. the sample size, the percentage of participants). Explanation – explain why this matters; for evaluation, explain why it is a strength or weakness. Link – connect back to the question or to a broader issue such as the approach’s assumptions.
要让段落连贯，请使用PEEL模型：Point（观点）— 提出评价点或描述细节；Evidence（证据）— 引用研究的具体细节（如样本量、参与者的百分比）；Explanation（解释）— 解释其意义；评价时需说明为什么这是一个优点或缺点；Link（联系）— 回扣题目或关联到更广的议题，例如该取向的假设。
For example, when evaluating Milgram: Point: A strength is the high level of control. Evidence: The experimenter used a fixed script and a standardised shock generator. Explanation: This increases reliability because other researchers can replicate the procedure. Link: Therefore the findings on obedience are more trustworthy. Every body paragraph should follow this flow.
例如，评价Milgram研究时：观点：一个优点是高度控制。证据：实验者使用固定脚本和标准化的电击发生器。解释：这提升了信度，因为其他研究者可以重复该程序。联系：因此关于服从的研究结果更可信。每个主体段落都应遵循这个流程。
4. How to Describe a Study Concisely | 如何简洁地描述一项研究
A complete study description must include four essential elements: Aim – what the researcher wanted to find out. Procedure – brief detail about the sample, design, apparatus and what participants were asked to do. Results – key quantitative or qualitative findings (include numbers where possible). Conclusion – what the researcher concluded and how it relates to the aim.
完整的研究描述必须包含四个关键要素：目的（Aim）— 研究者想探究什么；过程（Procedure）— 简要说明样本、设计、仪器以及被试被要求做什么；结果（Results）— 关键定量或定性发现（尽可能包含数字）；结论（Conclusion）— 研究者得出什么结论，以及如何与目的关联。
For an 8-mark essay, aim to write approximately two paragraphs: the first covering aim and procedure, the second covering results and conclusion. Avoid adding irrelevant background. Use technical terms such as ‘repeated measures design’, ‘standardised instructions’ or ‘inter-rater reliability’ to show depth.
在8分论文中，最好写约两个自然段：第一段涵盖目的和过程，第二段涵盖结果与结论。不要添加无关背景。使用“重复测量设计”“标准化指导语”或“评分者间信度”等技术术语来体现深度。
5. How to Evaluate Studies: The GRAVE Framework | 如何评价研究：GRAVE框架
GRAVE is a powerful evaluation mnemonic for CAIE essays. Each letter prompts a different angle of critical thinking:
- Generalisability – Can the findings be applied to other people or settings? Consider sample size, sampling method and cultural factors.
- Reliability – Can the study be replicated and produce consistent results? Look for standardised procedures, controlled variables and inter-rater reliability.
- Application – Can the findings be used in real-life settings such as schools, therapy or legal systems?
- Validity – Did the study measure what it intended to measure? Discuss internal validity (control of extraneous variables) and ecological validity (realism).
- Ethics – Were participants protected from harm? Consider informed consent, deception, right to withdraw and debriefing.
GRAVE是CAIE论文写作中强有力的评价口诀。每个字母都提示一个批判性思考的角度：
- G（普遍性）— 结果能否推广到其他人或情境？考量样本量、取样方法以及文化因素。
- R（信度）— 研究能否被复制并产生一致结果？审视标准化程序、控制变量和评分者间信度。
- A（应用性）— 研究结果能否用于学校、治疗或法律系统等现实场景？
- V（效度）— 研究是否测量了预期内容？讨论内部效度（无关变量控制）和生态效度（真实性）。
- E（伦理）— 参与者是否免受伤害？考虑知情同意、欺骗、退出权以及事后说明。
Always explain why a point is a strength or weakness and support it with specific evidence from the study. For instance, “The study lacked population validity because the sample consisted only of American male students, making it difficult to generalise to females or other cultures.”
务必解释该点为什么是优点或弱点，并用研究中的具体证据支撑。例如：“该研究缺乏人群效度，因为样本仅由美国男性学生组成，因此很难推广到女性或其他文化。”
6. Structuring an 8-Mark ‘Describe’ Essay | 构建8分“描述”论文
For an 8-mark describe essay, follow this simple template:
- Paragraph 1: State the aim and the background context if relevant. Summarise the procedure, including sample details (number, age, method of allocation) and what participants actually did.
- Paragraph 2: Present the key results, using precise numbers where available. State the conclusion drawn by the researcher and link it back to the aim.
在8分描述论文中，参照以下简单模板：
- 第一段：写出研究目的，如相关可提背景。概括过程，包括样本细节（人数、年龄、分配方法）以及被试实际做了什么。
- 第二段：呈现关键结果，凡有数字务必精准。阐述研究者得出的结论并回扣目的。
Do not include any evaluation or discussion of strengths and weaknesses in a pure ‘describe’ question, as marks are only awarded for knowledge and understanding. Keep every sentence factual and directly linked to the core study.
在纯“描述”题中不要加入任何评价或优缺点讨论，因为分值仅给知识与理解。确保每句话都是事实性内容并直接关联核心研究。
7. Structuring a 12-Mark ‘Describe and Evaluate’ Essay | 构建12分“描述与评价”论文
A 12-mark essay should allocate roughly half the content to description and half to evaluation. A recommended structure is:
- Short introduction: State the aim of the study and name the psychologist(s).
- Description paragraph: Concise procedure and results, using the four-element model from Section 4. Keep this tight—do not exceed one third of your total answer.
- Evaluation paragraph 1: Use GRAVE to unpack a strength (e.g. reliability) with evidence and explanation.
- Evaluation paragraph 2: Address a weakness (e.g. low ecological validity) with specific evidence.
- Evaluation paragraph 3: Introduce a second weakness or a counter-argument (e.g. a conflicting study or ethical criticism).
- Brief conclusion: Summarise the overall value of the study, linking back to the approach’s usefulness.
12分论文大致应将一半篇幅用于描述，一半用于评价。推荐结构如下：
- 简短引言：写出研究目的并提及心理学家名字。
- 描述段：用第4节的四要素模型简述过程和结果。段落要紧凑，不超过总篇幅的三分之一。
- 评价段1：用GRAVE展开一个优点（如信度），附证据及解释。
- 评价段2：论述一个缺点（如生态效度低），附具体证据。
- 评价段3：引入第二个缺点或一个反面论点（例如矛盾的研究或伦理批评）。
- 简短结论：总结研究的整体价值，回扣该取向的有用性。
Balance is crucial: if you write two pages of description and only four lines of evaluation, you limit your AO3 marks to roughly 2 out of 6. Aim for at least two well-developed evaluation paragraphs with the PEEL pattern.
平衡至关重要：如果写了满满两页描述却只有四行评价，你的AO3得分就会被限制在2分左右（满分6分）。至少写两个充分展开的PEEL评价段落。
8. Model Answer: 8-Mark Describe Essay on Dement & Kleitman (1957) | 范文：Dement & Kleitman (1957) 8分描述性论文
Dement and Kleitman (1957) aimed to investigate the relationship between rapid eye movements (REM) and the content of dreams. The study used nine adult participants (seven male, two female) who slept in a laboratory for several nights. Electrodes were attached near their eyes to record eye movements, and an electroencephalograph (EEG) measured brain activity. Participants were awakened at various times during the night, either during REM periods or non-REM (NREM) sleep, and asked to report whether they had been dreaming and to describe the dream content.
Dement和Kleitman (1957) 旨在研究快速眼动睡眠与梦境内容之间的关系。该研究使用了九名成人参与者（七男两女），他们在实验室中连续数晚睡眠。在眼睛附近贴上电极以记录眼动，并用脑电图测量脑波活动。参与者在夜间不同时间被唤醒（REM期或非REM期），并报告是否在做梦以及描述梦境内容。
The results showed a strong correlation between REM sleep and dream recall. Participants reported dreams on approximately 80% of REM awakenings but only on about 7% of NREM awakenings. Additionally, the duration of the REM period was positively correlated with the estimated length of the dream narrative. When participants were awakened after 15 minutes of REM, they described longer dreams than after 5 minutes of REM. The researchers also found that the pattern of eye movements appeared to relate to the dream content; for example, a participant who made mainly vertical eye movements reported dreaming about climbing a ladder.
结果显示，REM睡眠与梦境回忆之间存在强相关。在REM唤醒中约80%报告了梦境，而在非REM唤醒中仅有约7%。此外，REM期的持续时间与梦境叙事长度呈正相关：在15分钟REM后唤醒的参与者描述的梦境比5分钟REM后唤醒的更长。研究者还发现眼动模式与梦境内容有关；例如，一名主要表现出垂直眼动的参与者报告梦到爬梯子。
Dement and Kleitman concluded that REM sleep is closely linked with dreaming, suggesting that dreaming occurs during specific physiological states. The findings supported a biological basis for dreaming and established an objective method for studying dream content. This conclusion marked a key turning point in sleep research by moving beyond subjective self-reports alone.
Dement和Kleitman得出结论，REM睡眠与做梦密切相关，表明做梦发生在特定的生理状态下。该发现为梦境的生物学基础提供了支持，并建立了一套研究梦境内容的客观方法。这一结论超越了单纯的主观自我报告，成为睡眠研究的重要转折点。
9. Model Answer: 12-Mark Describe and Evaluate Essay on Bandura et al. (1961) | 范文：Bandura et al. (1961) 12分描述与评价论文
Bandura, Ross and Ross (1961) aimed to investigate whether children would imitate aggressive behaviour modelled by an adult, supporting the social learning theory. The researchers used a sample of 72 children (36 boys and 36 girls) aged 3 to 6 years from Stanford University Nursery School. A matched pairs design was used to allocate children to an aggressive model condition, a non-aggressive model condition or a control group, controlling for baseline levels of aggression. In the aggressive condition, each child observed an adult model attack a Bobo doll with physical and verbal aggression. The child was then taken to a room containing toys, including the Bobo doll, and observed through a one-way mirror.
Bandura, Ross和Ross (1961) 旨在研究儿童是否会模仿成人榜样表现出的攻击行为，以此支持社会学习理论。研究者样本为斯坦福大学附属托儿所72名3至6岁儿童（36名男孩、36名女孩）。采用匹配配对设计将儿童分配至攻击榜样组、非攻击榜样组或控制组，并控制了攻击性基线水平。在攻击条件下，儿童观察到一个成人榜样对Bobo玩偶实施身体和言语攻击。随后儿童被带入一个放有Bobo玩偶等玩具的房间，通过单向镜进行观察。
The results showed clear evidence of imitation. Children in the aggressive condition displayed significantly more physical and verbal aggression towards the Bobo doll than children in the other two groups. Boys exhibited more physical aggression than girls, especially when the model was male. Bandura et al. concluded that children can learn aggressive behaviour through observation and imitation, even without direct reinforcement, supporting the concept of vicarious learning.
结果清晰显示了模仿证据。攻击条件下的儿童对Bobo玩偶表现出的身体和言语攻击显著多于其他两组。男孩比女孩表现出更多身体攻击，当榜样为男性时尤为明显。Bandura等人得出结论，儿童即便没有直接强化，也能通过观察和模仿习得攻击行为，这支持了替代性学习的理念。
One strength of Bandura et al. is the high level of internal validity. The study used a matched pairs design to control for pre-existing levels of aggression, and the observation took place in a standardised room with a one-way mirror, reducing demand characteristics. This means that the differences in aggression between conditions can be more confidently attributed to the modelling variable rather than extraneous factors, strengthening the causal link between observation and imitation.
Bandura研究的一个优点是内部效度高。该研究采用匹配配对设计控制了事前的攻击水平，并在标准化房间内通过单向镜进行观察，从而降低了需求特征的影响。这意味着不同条件间攻击行为的差异可以更确定地归因于榜样变量而非无关因素，从而加强了观察与模仿之间的因果关系。
However, the study has been criticised for low ecological validity. The laboratory setting and the use of a Bobo doll, which is designed to be hit, may not represent how children behave in naturalistic settings. Children might have inferred that the experimenter expected them to hit the doll. Therefore, the aggressive behaviour observed may not reflect real-life aggression, limiting the applicability of the findings to everyday social learning situations.
然而，该研究因生态效度低而受到批评。实验室环境及使用专门设计用于击打的Bobo玩偶，可能不能代表儿童在自然环境中的行为。儿童可能推断实验者希望他们击打玩偶。因此，观察到的攻击行为未必反映真实的攻击性，限制了结果在日常社会学习情境中的适用性。
A further ethical concern is the psychological harm potentially caused to the children. Witnessing aggressive behaviour and then being encouraged to interact with the doll could have taught children new aggressive responses that they might use later. Additionally, there was no clear debriefing for the nursery-age participants. While the short-term harm may appear minor, modern ethical guidelines would require greater effort to protect young participants from possible imitation effects.
另一项伦理关切是对儿童造成的潜在心理伤害。目睹攻击行为后又被鼓励与玩偶互动，可能教会儿童新的攻击性反应并在日后再现。此外，对于幼儿参与者缺乏明确的事后说明。虽然短期伤害看似轻微，但现代伦理准则要求做出更大努力保护幼儿免受潜在的模仿效应影响。
10. Common Pitfalls and Exam-Day Tips | 常见错误与考试日技巧
Many students lose marks by describing studies without evaluation in a 12-mark question, or by listing evaluation points without explanation. Avoid writing “the study is reliable” without stating why. Another frequent mistake is spending too long on description and leaving only a rushed paragraph of evaluation. Always plan your time before writing. For a 12-mark essay, allocate approximately 6-7 minutes for description and 8-9 minutes for evaluation.
很多同学丢分是因为在12分题中只描述不评价，或罗列评价点却不加解释。不要只写“这个研究是可靠的”，却不说为什么。另一个常见错误是描述用时过长，评价只剩一段仓促的文字。动笔前一定要规划好时间。对于12分论文，分配约6–7分钟给描述，8–9分钟给评价。
Use the GRAVE framework as a mental checklist during the evaluation section. If you remember GRAVE, you will never run out of evaluation ideas. Practice writing model answers under timed conditions, then check them against the mark scheme. Finally, read the question carefully: if it asks “Describe and evaluate one study”, only pick one. Writing about two studies will not earn you extra marks and wastes time.
在评价部分把GRAVE框架当作心里的检查清单。只要记住GRAVE，就永远不会缺少评价思路。在限时条件下练习书写范文，再对照评分标准检查。最后，仔细读题：如果题目是“描述和评价一项研究”，请只选择一项。写两项研究非但不会加分，反而浪费时间。
