📚 Year 12 SQA Psychology: Key Points for the Experimental/Practical Assessment | 12年级SQA心理学：实验/实践考核要点
The practical assessment in Year 12 SQA Psychology requires you to plan, carry out, analyse and evaluate a small-scale research project. Your final submission is a structured research report that follows the conventions of psychological inquiry. This article breaks down the key points you must master to achieve top marks, from formulating a testable hypothesis to selecting the correct inferential statistic and discussing the validity of your findings.
12年级SQA心理学的实践考核要求你计划、实施、分析并评估一项小规模的研究项目，最终提交一份遵循心理学研究规范的结构化报告。从构建可检验的假设到选择正确的推理统计量，再到讨论研究结果的效度，本文详细拆解了你必须掌握的关键要点，助你稳拿高分。
1. Overview of the Practical Assessment | 实践考核概述
The SQA Higher Psychology Assignment is a single report worth 70 marks. You are expected to demonstrate skills in research design, data handling, statistical analysis and critical evaluation. The project must involve the collection of primary or secondary data and follow ethical principles. Your report is assessed under three main sections: Planning (including rationale, hypothesis and procedure), Analysis (descriptive and inferential statistics) and Evaluation (discussion, limitations and improvements).
SQA Higher心理学作业是一份价值70分的独立报告，你需要展现研究设计、数据处理、统计分析以及批判性评估等能力。该项目必须涉及一手或二手数据的收集，并遵循伦理原则。报告评分分为三个主要部分：计划（包括研究背景、假设和程序）、分析（描述统计和推理统计）以及评估（讨论、局限与改进建议）。
To succeed, you must understand that every decision you make — from the choice of design to the way you present your results — must be justified with reference to psychological knowledge and methodological rigour. The assignment is not simply about getting a significant result; it is about demonstrating scientific thinking.
要想成功，你必须明白，从研究设计的选择到结果的呈现方式，每一个决定都必须依据心理学知识和方法论的严谨性来论证。这项作业并不只是为了得到一个显著的结果，更重要的是展现科学的思维方式。
2. Choosing a Research Design | 选择研究设计
Your first crucial step is to decide on a research design that fits your aim. Common designs in Higher Psychology include the experiment (using an independent measures, repeated measures or matched pairs design), the quasi-experiment, the observational study, the questionnaire survey and the interview. For the practical assignment, many students choose a simple experiment because it allows clear manipulation of an independent variable (IV) and measurement of a dependent variable (DV), which lends itself well to statistical analysis.
你的第一个关键步骤是选择一个与研究目的相契合的设计。Higher心理学中常见的设计包括实验（采用独立测量、重复测量或配对组设计）、准实验、观察研究、问卷调查以及访谈。很多学生在实践作业中会选择简单的实验，因为它可以清晰地操纵自变量并测量因变量，非常适合统计分析。
When you select a design, you must be prepared to justify it. For instance, if you choose an independent measures design, you should discuss how you will allocate participants to conditions randomly to minimise participant variables. If you choose repeated measures, you need to explain how you will control order effects, for example through counterbalancing or randomisation of tasks.
在选择设计时，你必须准备好论证其合理性。例如，如果你选择独立测量设计，就要讨论如何将参与者随机分配到不同条件以最大程度减少参与者变量。如果选择重复测量设计，则需说明如何控制顺序效应，比如通过任务平衡或随机化。
Remember that a strong rationale links your design to previous research and the nature of the psychological phenomenon you are investigating. Avoid simply describing the design; critically explain why it is the most appropriate for your specific research question.
请记住，有力的研究背景阐述会将你的设计与前人的研究以及你所探究的心理现象的本质联系起来。不要仅仅描述设计，而要批判性地解释为什么它最适合你的特定研究问题。
3. Operationalising Variables | 操作化变量
Operationalisation means defining your IV and DV in clear, measurable terms. In an experiment on the effect of music on concentration, the IV might be 'the presence or absence of background music' and the DV 'the number of correct responses on a 20-item mental arithmetic test'. Both variables must be stated precisely enough that another researcher could replicate your study.
操作化是指用清晰、可测量的术语定义你的自变量和因变量。在一项关于音乐对专注力影响的实验中，自变量可以是“有无背景音乐”，因变量则是“在一项包含20道心算题的测试中正确回答的题数”。两个变量必须足够精确，以便其他研究者能够重复你的研究。
In Higher Psychology, you also need to identify and control at least one extraneous variable that could become a confounding variable if left unchecked. Standardised instructions, consistent timing and a controlled environment are typical controls. You must explicitly state how you minimised these unwanted influences.
在Higher心理学中，你还需要识别并控制至少一个额外变量，如果不加以控制，它就可能成为混淆变量。标准化的指导语、一致的时间安排和受控的环境是常见的控制手段。你必须明确陈述如何将这些无关影响降至最低。
Operationalising variables without over-simplifying the psychological construct is a skill. For instance, if you are measuring memory, state whether you are testing short-term recall, recognition or a specific type of memory, and use a standardised test or a clearly described task.
在不过度简化心理构念的前提下操作化变量是一项技能。例如，如果你要测量记忆，需要说明测试的是短时回忆、再认还是某种特定类型的记忆，并使用标准化测试或清晰描述的任务。
4. Writing Hypotheses | 撰写假设
Your hypothesis must be a clear, testable prediction about the relationship between the IV and the DV. You will write both an experimental (alternative) hypothesis and a null hypothesis. The experimental hypothesis should be directional (one-tailed) if previous research strongly points to a particular outcome, or non-directional (two-tailed) if the direction is uncertain. For example, a directional hypothesis: 'Participants who revise with background music will recall more words from a list than participants who revise in silence.'
你的假设必须是对自变量与因变量之间关系的一个清晰、可检验的预测。你需要同时写出实验假设（备择假设）和零假设。如果前人研究强烈指向某一特定结果，实验假设应为方向性（单尾）；如果方向不确定，则为非方向性（双尾）。例如，方向性假设：“在背景音乐下复习的参与者，从词表中回忆出的单词数量将多于在安静环境中复习的参与者。”
The null hypothesis always states that any difference or relationship observed is due to chance. For the example above, the null hypothesis would be: 'There will be no significant difference in the number of words recalled between participants who revise with background music and those who revise in silence; any observed difference is due to chance.'
零假设则总是陈述所观察到的任何差异或关系都是由偶然因素造成的。对于上述例子，零假设应为：“在背景音乐下复习的参与者与在安静环境中复习的参与者，其回忆出的单词数量无显著差异；任何观察到的差异均归因于偶然。”
At Higher level, you are expected to link your hypothesis to a psychological theory or model (e.g. working memory model, levels of processing) and to cite a relevant study. This demonstrates your understanding that hypotheses do not appear in a vacuum but are grounded in existing knowledge.
在Higher级别，你需要将假设与心理学理论或模型（如工作记忆模型、加工水平说）联系起来，并引用相关研究。这体现了你的理解：假设并非凭空出现，而是植根于现有知识。
5. Sampling Methods | 抽样方法
The target population is the whole group you are interested in; your sample is the subset that actually takes part. In the practical assignment, you must describe your sampling method, justify it and acknowledge its limitations. Common methods include opportunity sampling (using people who are available), volunteer/self-selected sampling (participants respond to an advert) and random sampling (every member of the target population has an equal chance of being selected).
目标总体是你感兴趣的整个群体，样本则是实际参与研究的那部分个体。在实践作业中，你必须描述抽样方法、论证其合理性并承认其局限性。常见的方法包括机会抽样（使用方便找到的人）、志愿者/自选抽样（参与者回应广告）和随机抽样（目标总体的每个成员都有均等被选中的机会）。
Most Higher projects use opportunity sampling because of practical constraints. If you do this, do not simply say it is convenient; explain that while it is quick and ethical, it may produce a biased, unrepresentative sample. You could mention that the sample is likely to consist of students of a similar age and educational background, which limits the generalisability of the findings.
由于实际条件的限制，大多数Higher项目使用机会抽样。如果你采用这种方法，不要仅仅说它方便；要解释虽然它快捷且符合伦理，但可能产生有偏差、不具代表性的样本。你可以提到样本可能由年龄和教育背景相似的学生组成，这限制了研究结果的普适性。
Also specify the size of your sample and how participants were assigned to conditions if using an independent design. A minimum of 10 participants per condition is advisable to run basic non-parametric tests, though larger samples improve reliability.
还要明确说明样本量，以及如果你使用独立设计，参与者是如何被分配到不同条件的。建议每个条件至少有10名参与者，以便进行基本的非参数检验，不过更大的样本量能提高信度。
6. Ethical Guidelines | 伦理准则
Ethics are paramount in all SQA practical work. You must show evidence of obtaining informed consent, guaranteeing the right to withdraw, protecting confidentiality, avoiding deception (or justifying any minor deception and arranging debrief), and safeguarding participants from physical and psychological harm. All of these must be explicitly addressed in the procedure section of your report.
伦理在所有SQA实践工作中都至关重要。你必须提供证据，证明已经获得知情同意、确保参与者有权随时退出、保护隐私、避免欺骗（或为任何轻微欺骗提供理由并安排事后解说），以及保护参与者免受身心伤害。所有这些都必须在报告的“程序”部分明确说明。
For example, you should state that you gave participants a detailed information sheet and a consent form, informing them of the study's purpose in broad terms, their tasks and their right to withdraw data. If you used anonymised codes, explain that no names were recorded. If you used a sensitive topic, describe the support arrangements.
例如，你应该说明，你向参与者提供了详细的信息表和知情同意书，大致告知研究目的、任务以及他们有权撤回数据。如果使用了匿名编码，要解释没有记录姓名。如果涉及敏感话题，要描述支持措施。
Remember that the SQA expects you to follow the British Psychological Society (BPS) Code of Ethics and Conduct. Any lack of attention to ethics can seriously undermine your marks, even if the rest of the report is strong.
请记住，SQA要求你遵循英国心理学会（BPS）的伦理准则。任何对伦理的忽视都可能严重拉低你的分数，即使报告的其他部分很出色。
7. Data Collection and Procedure | 数据收集与程序
Your procedure should read like a recipe: a step-by-step account of exactly what you did, so that replication is possible. Include details of the setting, materials, timings, standardised instructions, debriefing and how data were recorded. Keep it concise but precise; omit unnecessary commentary.
你的程序应该像一份食谱：一步步地准确记录你所做的一切，以便别人可以重复实验。要详细说明环境、材料、时间安排、标准化指导语、事后解说以及数据是如何记录的。保持简洁但精准，省略不必要的评论。
Data can be collected through numerical scores (e.g. number of words recalled, rating scales), categorised behaviours (e.g. helpful/unhelpful actions) or responses to questionnaires. Ensure that the raw data are clearly presented in an appendix and that you have a well-organised table of results for each participant in the results section.
数据可以通过数字分数（如回忆出的单词数、评分量表）、分类行为（如助人/非助人行为）或问卷回答来收集。确保原始数据清晰地呈现在附录中，并且在结果部分为每位参与者准备了整理有序的数据表。
If you used a standardised test or stimulus materials, reference them. If you created your own materials, include them in the appendices. Every element of your procedure should align with your aim, hypothesis and design.
如果你使用了标准化测试或刺激材料，请注明出处。如果是自己设计材料，则将其附在附录中。你程序的每一个要素都应与你的目的、假设和研究设计保持一致。
8. Descriptive Statistics | 描述统计
Descriptive statistics summarise your data and allow you to spot patterns. At Higher level, you must calculate a measure of central tendency (mean, median or mode) and a measure of dispersion (range, interquartile range or standard deviation). You should choose the most appropriate measures given the type of data (nominal, ordinal or interval) and the presence of outliers.
描述统计可以总结数据特征并帮助你发现模式。在Higher级别，你必须计算集中趋势的度量（均值、中位数或众数）和离散程度的度量（极差、四分位距或标准差）。你应当根据数据类型（称名、顺序或等距）以及是否存在异常值，选择最合适的度量。
For interval data with no extreme scores, the mean and standard deviation are powerful. For skewed data or small samples, the median and interquartile range are more robust. Always present your descriptive statistics in a clear table or summarise them in a sentence and briefly explain what they suggest about your data.
对于没有极端值的等距数据，均值和标准差最有效。对于偏态数据或小样本，中位数和四分位距更为稳健。一定将描述统计结果展示在清晰的表格中，或用一句话总结，并简要说明它们揭示了数据的什么特征。
rs is not enough; you must interpret them in the context of your hypothesis. For instance, " than for Condition B (M = 9.1), suggesting a potential effect of the independent variable."
仅仅报告数字是不够的，你必须结合假设来解读。例如，“条件A的平均回忆得分（M = 12.3）高于条件B（M = 9.1），暗示自变量可能存在效应。”
9. Choosing and Applying Inferential Statistics | 选择与应用推理统计
Inferential statistics allow you to decide whether your results are statistically significant — that is, unlikely to have occurred by chance. The SQA Higher Psychology course focuses on non-parametric tests. You must select an appropriate test based on the research design and the level of measurement.
推理统计让你能够判断结果是否具有统计显著性——即结果不大可能由偶然因素造成。SQA Higher心理学课程侧重于非参数检验。你必须根据研究设计和测量尺度选择合适的检验方法。
Use the following decision table to guide your choice:
| Design | Data Type | Recommended Test |
|---|---|---|
| Independent groups | Ordinal or interval (difference) | Mann-Whitney U test |
| Independent groups | Nominal (categorical) | Chi-squared (χ²) test for independence |
| Repeated measures / matched pairs | Ordinal or interval (difference) | Wilcoxon Signed Ranks test |
| Repeated measures / matched pairs | Nominal (categorical) | Binomial Sign test |
利用以下决策表来指导你的选择：
| 设计 | 数据类型 | 推荐检验 |
|---|---|---|
| 独立组设计 | 顺序或等距（差异） | Mann-Whitney U检验 |
| 独立组设计 | 称名（分类） | 卡方(χ²)检验（独立性） |
| 重复测量/配对组 | 顺序或等距（差异） | Wilcoxon符号秩检验 |
| 重复测量/配对组 | 称名（分类） | 二项符号检验 |
ritical value from tables. You must then state whether the result is significant and whether you reject the null hypothesis. Finally, write a clear conclusion in words related to the original hypothesis.
选定检验后，说明显著性水平（通常为p ≤ 0.05），计算观测值（如U = 23, T = 12），并将其与临界值表进行比较。然后，你必须说明结果是否显著，以及是否拒绝零假设。最后，用通俗语言写出与原始假设相关的明确结论。
10. Presenting Results and Data Visualisation | 呈现结果与数据可视化
Your results section should include both descriptive and inferential statistics presented in a logical order. In addition to tables, you should include an appropriate graph such as a bar chart (for comparing conditions) or a scattergram (for correlations). Label all axes clearly, use an informative title and ensure the graph is correctly scaled and fits the data type.
你的结果部分应包含描述统计和推理统计，并按照逻辑顺序呈现。除了表格，你还应绘制合适的图表，比如条形图（用于比较不同条件）或散点图（用于相关分析）。清楚地标注所有坐标轴，使用信息充分的标题，并确保图形比例正确且与数据类型相符。
Avoid adding unnecessary colour or 3D effects; a clean, standardised presentation is preferred in psychological reporting. Directly underneath the graph or table, provide a brief sentence explaining what the visual representation shows, linking it to your descriptive statistics.
避免添加不必要的颜色或三维效果；心理学报告偏爱简洁、标准化的呈现方式。在图表正下方，用简短的句子说明该可视化的内容，并将其与你的描述统计联系起来。
Remember that the results section should contain only the findings, not interpretation. Any discussion of what the results mean belongs in the discussion section. This separation of facts from interpretation is a core discipline in psychology.
记住，结果部分只应包含研究发现，不应进行解释。任何关于结果意义的讨论都应放在讨论部分。这种将事实与解释分开的做法是心理学的一门核心规范。
11. Discussion, Evaluation and Validity | 讨论、评估与效度
In the discussion, you must first summarise your main findings in plain English and relate them back to the hypothesis and the theory cited in your introduction. State whether your results support the experimental hypothesis or not, and offer a psychological explanation for the outcome.
在讨论部分，你必须先用通俗语言总结主要发现，并将其与假设以及引言中引用的理论联系起来。说明你的结果是否支持实验假设，并从心理学角度解释这一结果。
Critical evaluation is essential. Discuss the internal validity of your study: were the IV and DV well operationalised? Were extraneous variables controlled? Consider reliability, including standardisation and the consistency of measurements. Also address ecological validity: does the artificial nature of the task or setting limit how far the findings can be generalised to real life?
批判性评估至关重要。讨论研究的内部效度：自变量和因变量是否被很好地操作化？额外变量是否得到控制？考虑信度，包括程序标准化和测量的一致性。还要讨论生态效度：任务或情境的人为性是否限制了研究结果推广到现实生活的程度？
You must identify at least two significant limitations of your investigation and, for each, suggest a realistic improvement that could be implemented if the study were replicated. This demonstrates your evaluative skills and your ability to think like a researcher.
你必须指出自己研究的至少两个重要局限，并针对每个局限提出一个切实可行的改进建议，说明如果在重复研究中可以如何实施。这展现了你的评估能力和像研究者一样思考的素养。
12. Structuring the Research Report | 研究报告的结构
The SQA expects a very specific format. Your report should contain the following sections in order: Title, Abstract, Introduction (including aim, rationale and hypotheses), Method (design, participants, apparatus/materials, procedure, ethics), Results (descriptive and inferential statistics with graph), Discussion (summary, explanation, evaluation and references) and Appendices (raw data, calculations, materials).
SQA对报告格式有非常具体的要求。你的报告应按顺序包含以下部分：标题、摘要、引言（包括研究目的、背景和假设）、方法（设计、参与者、仪器/材料、程序、伦理）、结果（描述和推理统计及图表）、讨论（总结、解释、评估及参考文献）和附录（原始数据、计算过程、材料）。
Every section must be clearly labelled. Referencing should follow the Harvard system as prescribed by SQA. Common pitfalls include mixing methods into results, placing interpretation in the results section, and forgetting to append the raw data or consent forms. A checklist approach during final revision can save marks.
每个部分都必须清晰标注。参考文献格式应遵循SQA规定的哈佛系统。常见的失误包括将方法混入结果、在结果部分进行解读，以及忘记附上原始数据或同意书。最后修订时采用清单式检查可以有效保住分数。
Before submission, double-check that your hypothesis is operationally specific, your statistics are correctly calculated and compared with critical values, your graph is labelled, your evaluation explicitly references concepts like internal/external validity, and that the whole report reads as a coherent piece of scientific writing.
提交前，请再次检查你的假设是否操作化得具体明确，统计量是否计算正确并与临界值比较，图表是否标注完整，评估部分是否明确提及内部/外部效度等概念，以及整份报告是否读起来像一篇连贯的科学作品。
The practical assignment is your opportunity to demonstrate the full range of research skills that psychology demands. With careful attention to these key points, you can produce a report that is not only methodologically sound but also genuinely insightful.
实践作业是你展示心理学要求的所有研究技能的机会。只要仔细把握上述关键要点，你就能撰写出一份不仅方法论上扎实，而且真正富有洞见的报告。
