1. Understanding Independent and Dependent Variables | 理解自变量和因变量
A high-frequency topic is the identification of the independent variable (IV) and dependent variable (DV) in an experiment. The IV is what the researcher changes or manipulates. The DV is what the researcher measures. A typical mistake is identifying the DV as the condition being manipulated rather than the outcome. For instance, in a study testing whether caffeine (cups of coffee) affects reaction time (in milliseconds), the IV is the number of cups of coffee, and the DV is the reaction time. Students often wrongly label the participants or the coffee itself as the DV. Remember: the IV causes a change, and the DV shows the effect.
高频考点是实验中对自变量（IV）和因变量（DV）的识别。自变量是研究者改变或操纵的变量。因变量是研究者测量的结果。一个典型的错误是把因变量当作被操纵的条件，而不是结果。例如，在一项测试咖啡因（咖啡杯数）是否影响反应时间（毫秒）的研究中，自变量是咖啡杯数，因变量是反应时间。学生经常错误地将参与者或咖啡本身标记为因变量。记住：自变量引起变化，因变量显示效果。
2. Writing a Testable Hypothesis | 写出可检验的假设
A hypothesis must be a clear, testable statement predicting the relationship between the IV and DV. Many students lose marks by writing a general question instead of a directional or non-directional hypothesis. An acceptable directional hypothesis: ‘Participants who drink 2 cups of coffee will have faster reaction times than participants who drink 0 cups.’ A common error is to include ‘I think’ or ‘In my opinion’, making it subjective rather than scientific. The hypothesis must not be a question and should use operationalised terms (exactly how variables are measured).
假设必须是一个清晰、可检验的陈述，预测自变量和因变量之间的关系。许多学生因写成一般性问题，而不是方向性或非方向性假设而丢分。一个可接受的方向性假设：”喝两杯咖啡的参与者将比不喝咖啡的参与者有更快的反应时间。”常见的错误是包含”我认为”或”依我之见”，使假设变得主观而不科学。假设不能是问句，并且应当使用可操作化的术语（即变量如何测量必须明确）。
3. Ethical Guidelines in Psychological Research | 心理学研究中的伦理准则
Ethical issues are heavily examined in SQA Psychology. The core ethical principles are informed consent, deception, protection from harm, right to withdraw, confidentiality, and debriefing. A frequent misconception is believing that if you get consent, you can deceive participants in any way. In fact, deception must be justified and minimised. Another common mistake is mixing up confidentiality (keeping data anonymous) with privacy (observing people in private settings). Students often fail to explain how a researcher could have improved a study’s ethics; always link improvements to specific principles.
伦理问题在SQA心理学中考查较多。核心伦理原则是知情同意、欺骗、免受伤害、退出权、保密和事后说明。一个常见的误解是认为只要获得同意，就可以以任何方式欺骗参与者。实际上，欺骗必须有正当理由并尽量减少。另一个常见的错误是将保密（保持数据匿名）与隐私（在私人场合观察人们）混淆。学生在解释研究者如何改进研究的伦理性时常常失败；务必将改进措施与具体原则联系起来。
4. The Multi-Store Model of Memory | 记忆的多储存模型
Atkinson and Shiffrin’s multi-store model describes memory as consisting of sensory register, short-term memory (STM), and long-term memory (LTM). A high-frequency question asks students to label the flow of information and the processes of attention and rehearsal. An easy mistake is to state that all sensory information passes to STM; in fact, only that which is paid attention to moves on. Also, the capacity and duration of STM (7 ± 2 items, about 18–30 seconds) and LTM (potentially unlimited) are often reversed by students under exam pressure. Linking each store to a real-life example strengthens your answer.
阿特金森和希夫林的多储存模型将记忆描述为由感觉登记、短时记忆（STM）和长时记忆（LTM）组成。一个高频考题要求学生标出信息流向和注意与复述的过程。容易出错的地方是声称所有感觉信息都进入STM；事实上，只有被注意到的信息才会继续传递。此外，STM的容量和持续时间（7±2个项目，约18–30秒）和LTM（潜在无限）在考试压力下经常被学生颠倒。将每个储存与一个现实生活例子联系起来能够加强你的答案。
5. Attachment Types: Secure, Insecure-Avoidant, Insecure-Resistant | 依恋类型：安全型、不安全-回避型、不安全-反抗型
Ainsworth’s Strange Situation identified three main attachment types. Secure infants explore the room freely, show distress when the caregiver leaves, and are easily comforted upon return. Insecure-avoidant infants appear indifferent to the caregiver’s presence or absence. Insecure-resistant infants cling yet resist comfort, showing ambivalence. Students regularly confuse avoidant and resistant behaviour in scenario questions. The key is to recall that avoidant infants turn away or ignore the caregiver, while resistant infants both seek and reject contact, often with anger.
安斯沃思的陌生情境法识别出三种主要依恋类型。安全型婴儿自由探索房间，当照看者离开时表现出痛苦，并在返回时容易得到安慰。不安全-回避型婴儿对照看者的在场或离开显得漠不关心。不安全-反抗型婴儿既粘人又抗拒安慰，表现出矛盾心理。学生在场景题中经常混淆回避型和反抗型行为。关键是记住回避型婴儿会转身或忽视照看者，而反抗型婴儿既寻求又拒绝接触，常常带有愤怒。
6. Experimental Designs: Independent Groups, Repeated Measures, Matched Pairs | 实验设计：独立组、重复测量、匹配对
Choosing the right experimental design is a frequent topic. The following table summarises each design’s advantages and disadvantages, which are often mixed up in exams.
选择合适的实验设计是一个常见话题。下面的表格总结了每种设计的优缺点，这些在考试中经常被混淆。
| Design / 设计 | Key Feature / 关键特征 | Common Mistake / 常见错误 |
|---|---|---|
| Independent groups | Different participants in each condition. / 每个条件用不同的参与者。 | Thinking participant variables are eliminated; in fact they are a problem. / 认为消除了参与者变量；实际上它们是个问题。 |
| Repeated measures | Same participants in all conditions. / 同一批参与者参加所有条件。 | Forgetting to mention order effects as a disadvantage. / 忘记提到顺序效应是一个缺点。 |
| Matched pairs | Different but matched participants on key traits. / 不同但基于关键特质匹配的参与者。 | Assuming it is always the best design; matching is time-consuming and not perfect. / 假设它总是最好的设计；匹配耗时且不完美。 |
Students commonly confuse the problem of individual differences in independent groups with the problem of order effects in repeated measures. When evaluating a design, always identify the specific weakness relating to the chosen design.
学生通常将独立组中的个体差异问题与重复测量中的顺序效应问题相混淆。在评价一个设计时，要始终指出与该设计相关的具体弱点。
7. Conformity and Obedience: Asch and Milgram | 从众与服从：阿希和米尔格拉姆
Social influence is examined through classic studies. Asch’s line judgement study showed that people conform to a majority even when the answer is clearly wrong. Milgram’s obedience study demonstrated that people obey authority figures even to the point of harming others. A high-frequency error is stating that Milgram studied conformity; he studied obedience. The two differ: conformity is yielding to group pressure with no direct request, while obedience is following an order from an authority figure. In application questions, check whether a group norm or a direct command is present.
社会影响通过经典研究进行考查。阿希的线段判断研究表明，即使答案明显错误，人们也会从众于多数人。米尔格拉姆的服从研究表明，人们服从权威人物，甚至到伤害他人的程度。一个高频错误是说米尔格拉姆研究从众；他研究的是服从。两者不同：从众是对群体压力的屈服而没有直接的命令，而服从是听从权威人物的命令。在应用题中，检查是否存在群体规范还是直接命令。
8. Neurons and Synaptic Transmission | 神经元与突触传递
In the biological approach, you need to name the parts of a neuron: dendrites, cell body, axon, myelin sheath, and terminal buttons. A common diagram-labelling mistake is swapping the axon and dendrite directions. Dendrites receive signals and carry them towards the cell body; the axon carries signals away from the cell body. Synaptic transmission involves neurotransmitters crossing the gap (synaptic cleft) from the pre-synaptic neuron to bind to receptors on the post-synaptic neuron. Students often say the electrical signal jumps the gap; in fact, it is a chemical process at the synapse.
在生物学取向中，你需要说出神经元各部分的名字：树突、细胞体、轴突、髓鞘和终扣。一个常见的图表标注错误是搞反轴突和树突的方向。树突接收信号并传向细胞体；轴突将信号从细胞体传出。突触传递涉及神经递质跨越间隙（突触间隙），从突触前神经元到达突触后神经元的受体。学生经常说电信号跳过间隙；实际上，在突触处是一个化学过程。
9. Correlation Does Not Imply Causation | 相关并不意味着因果关系
Correlational analysis is a common stumbling block. A correlation coefficient (r) ranges from -1 to +1; +0.8 is a strong positive correlation, and -0.3 is a weak negative correlation. The most common mistake in Year 7 SQA exams is to conclude that a correlation means one variable causes the other. For example, a positive correlation between ice cream sales and drowning incidents does not mean ice cream causes drowning; a third variable (hot weather) explains both. Always suggest a possible extraneous or confounding variable in such questions.
相关分析是一个常见的绊脚石。相关系数（r）的范围从-1 到 +1；+0.8 是强正相关，-0.3 是弱负相关。七年级SQA考试中最常见的错误是得出结论说一项相关意味着一个变量导致了另一个变量。例如，冰淇淋销量与溺水事件呈正相关，并不意味着冰淇淋导致溺水；第三个变量（炎热天气）可以解释两者。在此类问题中，总要提出可能的外来或混淆变量。
10. Descriptive Statistics and Graph Interpretation | 描述统计与图表解读
Calculating the mean, median, mode, and range is a skill often tested with raw data. The mean is the arithmetic average, the median is the middle value, and the mode is the most frequent. A common mistake is confusing the median with the mean when data is skewed. For example, in a small dataset of reaction times: 200, 210, 220, 230, 800 ms. The mean would be pulled up by the 800 outlier (332 ms), but the median (220 ms) better represents the central tendency. In graph interpretation, students forget to refer to the axes labels and numerical data in their explanations; always quote data and units.
计算平均数、中位数、众数和全距是经常用原始数据考查的技能。平均数是算术平均值，中位数是中间的值，众数是最常出现的值。一个常见错误是当数据偏斜时混淆中位数和平均数。例如，在反应时间的小数据集中：200、210、220、230、800 毫秒。平均值会被 800 这个异常值拉高（332 毫秒），但中位数（220 毫秒）更能代表集中趋势。在图表解读中，学生在解释时会忘记参考轴标签和数值数据；务必引用数据和单位。
11. Sampling Methods and Bias | 抽样方法与偏差
Sampling techniques such as random, opportunity, and stratified sampling are often compared. Opportunity sampling involves selecting whoever is available, which is convenient but may produce a biased sample that does not represent the target population. Random sampling gives everyone an equal chance, but is not always practical. A common error is to state that opportunity sampling is always unrepresentative; it can be if the sample is drawn from a narrow setting, but sometimes it matches the target population by chance. When evaluating, always link the sampling method to the specific research aim and population.
抽样技术如随机抽样、机会抽样和分层抽样常被比较。机会抽样涉及挑选任何可用的人，这很方便，但可能产生一个有偏差的样本，不能代表目标总体。随机抽样给每个人平等的机会，但不总是可行的。一个常见错误是声称机会抽样总是不具代表性；如果样本取自狭窄的环境，可能会有偏差，但有时它恰好与目标总体吻合。在评价时，务必将抽样方法与具体的研究目的和总体联系起来。
12. Exam Technique: Command Words and Structuring Answers | 考试技巧：指令词和答案结构
Many marks are lost not through lack of knowledge but through misreading command words. ‘Identify’ requires a short, direct answer; ‘Describe’ needs detail of what happens; ‘Explain’ asks for reasons why; ‘Evaluate’ demands strengths and weaknesses. A trap in SQA papers is to write everything you know about a topic when the question only asks to ‘identify’ one factor. Another is failing to use the stimulus material in scenario-based questions. Always embed evidence from the scenario and link it to psychological concepts. Planning your answer with bullet points on the exam paper can help you stay focused and avoid waffle.
许多分数不是因知识匮乏而丢，而是因为误读指令词。’Identify’ 要求简短、直接的回答；’Describe’ 需要细节描述发生了什么；’Explain’ 要求给出原因；’Evaluate’ 要求给出优点和弱点。SQA试卷中的一个陷阱是，当问题只要求”identify”一个因素时，你却把自己知道的关于该话题的所有内容全写上去。另一个是没有在情景题中使用题干材料。一定要把情景中的证据融入答案并与心理学概念相联系。在试卷上用要点规划你的答案可以帮助你保持专注并避免啰嗦。
