在 GCSE 剑桥心理学考试中写出一篇高分论文，不仅需要熟悉理论，还必须理解考官的评分要求，搭建能覆盖每个评估目标的结构，并用精确的证据支撑观点。本指南将拆解一套行之有效的论文写作框架，并带你完整分析一篇关于记忆多储存模型的范文，让你清楚地看到如何把知识转化为高分。
1. Understanding the Exam Paper | 了解考试试卷
In the Cambridge IGCSE Psychology (0990) exam, the extended writing questions appear in both Paper 1 and Paper 2. Typically, you will face a 10-mark question that carries the command 'Describe and evaluate' or 'Discuss'. These questions are designed to test your ability to recall factual knowledge, apply it to scenarios or research, and critically analyse the strengths and weaknesses of a theory, study, or model.
在剑桥 IGCSE 心理学（0990）考试中，Paper 1 和 Paper 2 都会出现扩展写作题。通常你会遇到一道 10 分题，指令词为“描述并评价”或“讨论”。这些题目旨在考查你回忆事实知识的能力、将其应用到情境或研究中的能力，以及对一种理论、研究或模型的优缺点进行批判性分析的能力。
Remember, marks are not awarded simply for writing everything you know. The examiner uses a mark scheme tied to Assessment Objectives, so every paragraph must serve a clear purpose. A well-planned 10-mark essay should include accurate descriptions (AO1), appropriate application or use of research evidence (AO2), and a balanced evaluation (AO3).
请记住，考官不会仅仅因为你写满了知识点就给分。评分方案与评估目标紧密挂钩，因此每个段落都必须有明确的目的。一篇规划得当的 10 分论文应包含准确的描述（AO1）、恰当的应用或研究证据引用（AO2）以及均衡的评价（AO3）。
2. Command Words and Assessment Objectives | 指令词与评估目标
Different command words signal which skills the examiner wants to see. Understanding them is the first step to writing a focused answer.
不同的指令词提示考官想要考查的技能，理解这些词是写出聚焦答案的第一步。
| Command Word | What It Means | Primary AOs Tested |
|---|---|---|
| Describe | Give a detailed account of a theory, study, or model. | AO1 |
| Evaluate | Weigh up strengths and limitations, using evidence to support your judgement. | AO3 |
| Discuss | Provide a balanced review, including description and evaluation. | AO1 + AO3 |
| Explain | Show how or why something happens, often by referring to processes or mechanisms. | AO1 + AO2 |
For a 'Describe and evaluate' 10-mark question, you should aim to spend roughly one third of your answer on AO1 (description) and two thirds on AO3 (evaluation), while weaving in AO2 through the use of research to support points. This balance is key to accessing the top band.
对于一道“描述并评价”的 10 分题，你应当把大约三分之一的篇幅用在 AO1（描述）上，三分之二用在 AO3（评价）上，同时通过引用研究来支持观点，以此融入 AO2。这种平衡是拿到最高档的关键。
3. The PEEL Structure for Psychology Essays | 心理学论文的 PEEL 结构
Every paragraph in your essay should follow a clear structure, and PEEL is the most effective for GCSE psychology. It stands for Point, Evidence, Explanation, and Link.
你论文中的每个段落都应遵循清晰的结构，PEEL 对 GCSE 心理学最为有效。它代表观点、证据、解释和链接。
- Point: State the main idea of the paragraph, such as a strength or a limitation.
- Evidence: Support the point with a specific study or research finding, e.g. 'Peterson and Peterson (1959) found that...'
- Explanation: Show how the evidence proves your point. Do not just drop in a study; explain what it means for the theory.
- Link: Connect back to the question or to the next paragraph. This could be a mini-conclusion of the point or a signpost to the evaluation you will offer next.
- 观点：陈述段落的主要思想，比如一个优点或局限。
- 证据：用具体的研究或发现来支撑观点，例如“Peterson 和 Peterson（1959）发现……”
- 解释：说明证据如何证明你的观点。不要只是丢出一个研究；要解释它对理论意味着什么。
- 链接：回扣题目或引出下一段。这可以是一个小结论，也可以提示接下来你将提供的评价。
Applying PEEL consistently stops your essay from becoming a list of unconnected facts and forces you to demonstrate higher-order thinking, which is exactly what AO3 values.
始终如一地运用 PEEL 可以避免论文变成互不关联的事实列表，并强制你展现出高阶思维，这正是 AO3 所看重的。
4. Planning Your Essay in Minutes | 几分钟内规划你的论文
It is tempting to start writing immediately, but a two-minute plan can prevent you from repeating ideas, missing evaluation, or running out of structure. Use a quick spider diagram or bullet points.
你很容易想立刻动笔，但花两分钟规划可以防止重复观点、遗漏评价或结构散乱。使用一个快速的气泡图或要点清单即可。
First, identify the theory or model in the question. Jot down the key components you need to describe. Next, list at least two strengths and two limitations, each paired with a piece of research evidence. Finally, think of a real-world application or a study that illustrates the concept (this will support AO2). Organise these ideas into a logical flow: introduction, description, application/evidence, evaluation, conclusion.
首先，确定题目中的理论或模型。草草记下你需要描述的关键要素。接着，列出至少两个优点和两个局限，每一项都要配上一条研究证据。最后，想一个现实应用或一项能说明该概念的研究（这将支持 AO2）。把这些想法组织成一个逻辑流程：引言、描述、应用/证据、评价、结论。
For example, the question 'Describe and evaluate the multi-store model of memory. (10)' would produce a plan like: define model; separate stores (sensory, STM, LTM); features of each store with studies (Miller, Peterson & Peterson); application – serial position effect; strengths – HM case; limitations – KF case, oversimplification; working memory model as alternative; conclusion.
比如，对于“描述并评价记忆的多储存模型（10 分）”这道题，你的规划可以是：定义模型；独立的储存库（感觉、短时、长时）；各储存库的特征及对应研究（Miller、Peterson 和 Peterson）；应用——序列位置效应；优点——HM 案例；局限——KF 案例、过度简化；工作记忆模型作为替代模型；结论。
5. Model Essay: Introduction and Outline | 范文：引言与大纲
Here is the introduction paragraph of a model essay. Notice how it defines the key term, names the theory and researchers, and provides a clear signpost of what the essay will cover.
以下是范文的引言段落。请注意它如何定义关键术语、点出理论和研究者，并清晰预示论文将涵盖的内容。
"Memory is a cognitive process that involves encoding, storing, and retrieving information. The multi-store model (MSM), proposed by Atkinson and Shiffrin (1968), provides a structural explanation of how memory works by dividing it into three unitary stores: sensory memory, short-term memory (STM), and long-term memory (LTM). This essay will describe the key features of each store and evaluate the model's strengths and limitations using research evidence."
“记忆是一种涉及编码、储存和提取信息的认知过程。由 Atkinson 和 Shiffrin（1968）提出的多储存模型（MSM）提供了一种关于记忆如何运作的结构性解释，它将记忆分为三个单一储存库：感觉记忆、短时记忆（STM）和长时记忆（LTM）。本文将描述各个储存库的主要特征，并利用研究证据评价该模型的优点和局限性。”
This introduction immediately shows the examiner that you understand the topic. It defines memory and the MSM (AO1), and it tells the reader that evaluation will follow, setting up a clear structure without wasting words.
这个引言立刻向考官展示了你对主题的理解。它定义了记忆和 MSM（AO1），并告诉读者评价将会随后展开，搭建了清晰的结构而没有赘字。
6. Model Essay: Describing the Multi-Store Model (AO1) | 范文：描述多重存储模型（AO1）
The next paragraph must describe the model in detail, using precise terminology and supporting studies. This is where you earn the bulk of your AO1 marks.
接下来的段落必须用精准的术语和支持性研究详细描述模型。这正是你赚取 AO1 分数的主要地方。
" ormation first enters sensory memory, which has a large capacity but a very brief duration – 2 items, as proposed by Miller (1956), and a duration of around 18 to 30 seconds without rehearsal, demonstrated by Peterson and Peterson (1959). Rehearsal helps to maintain information in STM and eventually transfers it into LTM. Long-term memory is believed to have potentially unlimited capacity and duration, and it codes information semantically."
“根据 MSM，信息首先进入感觉记忆，它的容量很大但持续时间很短——视觉刺激的停留不到半秒。如果对这些信息给予注意，它们就会进入 STM。短时记忆的容量有限，为 7±2 个组块，由 Miller（1956）提出，其持续时间在没有复述的情况下约为 18 到 30 秒，这由 Peterson 和 Peterson（1959）的实验所证实。复述有助于信息在 STM 中保持，并最终将其转入 LTM。长时记忆被认为拥有几乎无限的容量和持续时间，并以语义形式进行编码。”
Notice how each store is linked to a specific capacity or duration finding, rather than just listed. This use of evidence strengthens the description and subtly introduces AO2, as you are applying research to illustrate the model.
请注意每个储存库都关联了具体的容量或持续时间发现，而不是简单罗列。这种对证据的运用强化了描述，并巧妙地引入了 AO2，因为你正在应用研究来说明模型。
7. Model Essay: Applying Research (AO2) | 范文：应用研究（AO2）
AO2 in IGCSE Psychology is about applying knowledge to novel or familiar contexts. You can demonstrate this by explaining how a study or real-life phenomenon fits the model.
IGCSE 心理学中的 AO2 指的是将知识应用到新颖或熟悉的语境中。你可以通过解释某项研究或现实生活现象如何符合模型来展示这一点。
"The MSM can be used to explain the serial position effect observed in Murdock's (1962) free recall experiment. When participants recalled a list of words, they remembered items at the beginning (primacy effect) and the end (recency effect) better than those in the middle. According to the MSM, early words were rehearsed and transferred to LTM before STM capacity was exceeded, while the final words were still in STM at the time of recall. The middle words were displaced before they could be rehearsed, supporting the idea of separate storage systems."
“MSM 可以用来解释 Murdock（1962）自由回忆实验中观察到的序列位置效应。当被试回忆一系列单词时，他们对开头（首因效应）和结尾（近因效应）的单词记忆得比中间的更好。根据 MSM，开头的单词在 STM 容量被超过之前得到了复述并被转入 LTM，而结尾的单词在回忆时仍留在 STM 中。中间的单词在得到复述之前就被挤掉了，这支持了独立储存系统的观点。”
This paragraph goes beyond description by using the model to explain a specific set of results. It shows you can apply the theoretical framework logically, which is exactly what AO2 rewards.
这个段落超越了单纯的描述，利用模型来解释一组特定的实验数据。它表明你能够合乎逻辑地应用理论框架，这正是 AO2 所奖励的。
8. Model Essay: Evaluation Paragraph (AO3) | 范文：评价段落（AO3）
Evaluation must present a balanced review, with stand-alone paragraphs that each focus on one strength or limitation and unpack the evidence thoroughly.
评价必须呈现均衡的评述，用独立的段落分别论述一个优点或局限，并彻底展开证据。
"One strength of the MSM is the strong evidence for the separation of STM and LTM from case studies of amnesia. The famous case of patient HM (Scoville & Milner, 1957) showed that after the removal of his hippocampus, HM could hold information in STM but could not form new long-term memories. This suggests that the two stores are distinct and damage can impair one without affecting the other. However, the MSM has been criticised for oversimplifying memory. The case of KF (Shallice & Warrington, 1970) demonstrated that his STM was severely impaired for verbal material but much less so for visual information, implying that STM is not a single unitary store. Additionally, the model overemphasises the role of rehearsal; we often remember distinctive events without any rehearsal. These weaknesses led Baddeley and Hitch (1974) to propose the working memory model, which divides STM into multiple components. Despite these limitations, the MSM provided an important foundation and remains a useful starting point for understanding memory architecture."
“MSM 的一个优势在于，来自遗忘症案例研究的有力证据证实了 STM 和 LTM 的分离。著名的病人 HM 案例（Scoville 和 Milner，1957）显示，海马体被切除后，HM 能够在 STM 中保持信息，却无法形成新的长时记忆。这表明这两个储存库是分离的，损伤可以只影响其中一个而另一个不受影响。然而，MSM 也因过度简化记忆而受到批评。KF 案例（Shallice 和 Warrington，1970）表明，他的 STM 对言语材料受到严重损害，但对视觉信息的损害却小得多，这意味着 STM 并非单一的储存库。此外，该模型过分强调复述的作用；我们常常对某些特殊事件不加复述也能记住。这些弱点促使 Baddeley 和 Hitch（1974）提出了工作记忆模型，将 STM 划分为多个成分。尽管存在这些局限，MSM 提供了一个重要的基础，并且仍然是理解记忆架构的有益起点。”
This paragraph follows PEEL faithfully. Each point is supported by named research, the explanation connects the evidence to the theory, and the final sentence links the limitation to an alternative model, showing depth of understanding.
这个段落忠实地遵循了 PEEL 结构。每个观点都有具名研究支持，解释部分将证据与理论联系起来，最后一句话将局限与替代模型相联结，显示出理解的深度。
9. Model Essay: Conclusion | 范文：结论
A strong conclusion does not just repeat the introduction. It summarises the argument, weighs the evidence, and reaches a final judgement that directly answers the question.
一个出色的结论不是简单重复引言，而是概括论点、权衡证据，并得出一个直接回答题目的最终判断。
"In conclusion, the multi-store model offers a clear and influential framework for understanding memory as a sequential process. Research evidence, such as the case of HM and the serial position effect, supports the distinction between STM and LTM. Nonetheless, the model's oversimplification of short-term memory and its reliance on rehearsal limit its explanatory power. While more sophisticated models like the working memory model have since been developed, the MSM remains a valuable historical model that helped shape modern cognitive psychology."
“总而言之，多储存模型提供了一个清晰且有影响力的框架，将记忆理解为一个序列过程。诸如 HM 案例和序列位置效应等研究证据支持了 STM 和 LTM 的区分。然而，该模型对短时记忆的过度简化以及对复述的依赖限制了它的解释力。虽然此后发展出了像
