In AS WJEC Psychology, students often develop misunderstandings that can hinder their exam performance and deeper appreciation of the subject. These misconceptions arise from oversimplifications, confusion between similar concepts, or popular myths. This article identifies common pitfalls across various approaches and research methods, and provides clear corrections to help you avoid them. By tackling these errors head-on, you can strengthen your psychological knowledge and boost your confidence in tackling exam questions.
在AS WJEC心理学中，学生经常会产生一些误解，这些误解可能妨碍他们的考试成绩和对学科的深入理解。这些误区源于过度简化、相似概念混淆或常见的流行迷思。本文指出了横跨各种取向和研究方法的常见陷阱，并提供了清晰的纠正方法，帮助你避免这些错误。通过直面这些错误，你可以巩固心理学知识，增强应对考题的信心。
1. Correlations Prove Causation | 相关性证明因果关系
One of the most common mistakes is believing that a correlation between two variables automatically means that one variable causes the other. Students often interpret a positive correlation coefficient as evidence of causation. This is incorrect because correlation only describes a relationship, not a causal mechanism. A third variable, such as socioeconomic status, could be responsible for both, or the direction of causation could be reversed. To establish causation, a controlled experiment with random assignment is necessary. Always remember: correlation does not imply causation.
最常见的错误之一是认为两个变量之间的相关性自动意味着一个变量导致了另一个变量。学生常常把正相关系数理解为因果关系的证据。这是不正确的，因为相关性仅仅描述了关联性，而非因果机制。可能存在第三个变量（如社会经济地位）共同导致两者，或者因果方向可能相反。要确定因果关系，需要进行带有随机分配的对照实验。请牢记：相关性并不意味着因果关系。
To correct this, remind yourself of the criteria for establishing cause: covariance, temporal precedence, and elimination of alternative explanations. Observational and correlational studies can satisfy covariance but rarely eliminate alternatives. Only experiments can manipulate the independent variable and control extraneous variables. When analysing data in WJEC, look for whether the study design truly allows causal inference.
要纠正这一点，需要提醒自己确立因果关系的标准：共变、时间先后顺序以及排除其他解释。观察性和相关性研究能够满足共变性，但很少能排除其他解释。只有实验能够操纵自变量并控制无关变量。在WJEC考试分析数据时，要审视研究设计是否真正允许因果推断。
Additionally, even when causation seems plausible, be cautious of reverse causality. For example, a study might find that exercise correlates with lower depression, but it is possible that less depressed people are more likely to exercise. Always consider both directions.
此外，即使因果关系看似合理，也要警惕反向因果。例如，一项研究可能发现锻炼与较低抑郁水平相关，但可能性是，抑郁程度较轻的人更愿意锻炼。永远要考虑双向可能性。
2. A Non-Significant Result Means No Effect | 不显著结果意味着没有效果
Many students misinterpret a non-significant statistical test (e.g., p > 0.05) as proof that there is absolutely no difference or relationship in the population. This is a serious error. A non-significant result simply means that the data collected do not provide enough evidence to reject the null hypothesis; it does not confirm the null hypothesis. The study might have lacked statistical power due to a small sample size or a weak effect.
许多学生错误地将不显著的统计检验（如p > 0.05）解读为在总体中绝对没有差异或关系的证明。这是一个严重的错误。不显著的结果仅意味着所收集的数据没有提供足够证据来拒绝零假设；这并不证实零假设为真。研究可能由于样本量小或效应微弱而缺乏统计效力。
Failing to find an effect could be due to a Type II error, where the null hypothesis is false but not rejected. Researchers should consider confidence intervals and effect sizes, not just p-values. Always say ‘there is insufficient evidence to reject the null hypothesis’ rather than ‘the null hypothesis is true’. In essays, acknowledge that non-significance does not disprove a theory; it just fails to support it in the current study.
未能发现效应可能是由于第二类错误，即零假设为假但未被拒绝。研究者应考虑置信区间和效应量，而不仅仅是p值。永远表述为“没有足够证据拒绝零假设”，而不是“零假设为真”。在论文写作中，要承认非显著性结果并不能否定理论；它只是在当前研究中未能支持该理论。
3. Classical Conditioning Explains Voluntary Behaviour | 经典条件反射解释自愿行为
Students often claim that Pavlov’s dogs salivated because they were rewarded with food after ringing the bell, which is actually an operant conditioning contingency. In classical conditioning, a neutral stimulus (bell) becomes associated with an unconditioned stimulus (food) to elicit a reflexive response (salivation). The key is that the response is involuntary and elicited by the stimulus, not emitted to produce a consequence.
学生常声称巴甫洛夫的狗分泌唾液是因为在响铃后得到了食物奖励，这实际上是操作条件反射的机制。在经典条件反射中，中性刺激（铃声）与无条件刺激（食物）产生联结，从而引发反射性反应（唾液分泌）。关键在于反应是不随意的，由刺激引发，而不是为了产生后果而发出。
To avoid this, identify whether the behaviour is elicited by a preceding stimulus (classical) or shaped by its consequences (operant). Remember the S-R (stimulus-response) model vs. the three-term contingency (antecedent-behaviour-consequence). For example, a child cleaning their room to receive praise from parents is operant conditioning, whereas feeling anxious when entering a doctor’s surgery because of a past painful injection is classical conditioning.
避免混淆的关键是识别行为是由前因刺激引发的（经典性），还是由后果塑造的（操作性）。铭记S-R（刺激-反应）模型与三项术语关联（前因-行为-后果）的区别。例如，一个孩子为了获得家长表扬而打扫房间属于操作条件反射，而因过去经历疼痛注射从而一进入诊所就感到焦虑则属于经典条件反射。
4. Memory is an Accurate Recording of Events | 记忆是事件的准确记录
A persistent myth is that human memory functions like a video camera, faithfully recording and replaying events. This leads students to overestimate eyewitness testimony reliability. In reality, memory is a reconstructive process. Bartlett’s ‘War of the Ghosts’ study showed that recall becomes distorted to fit existing schemas. The table below contrasts common misconceptions with evidence-based realities.
一个顽固的迷思是，人类记忆像摄像机一样忠实地记录和回放事件。这导致学生高估了目击证人证词的可靠性。实际上，记忆是一个重构过程。巴特利特的“幽灵之战”研究表明，回忆会为了适应已有图式而被扭曲。下表对比了常见误区与基于证据的现实。
| Common Myth | Reality |
|---|---|
| Memory stores exact copies of events like a video recording. | Memory is reconstructed from fragments and is influenced by schemas, beliefs and post-event information. |
| Once stored, memories remain stable and unchanging. | Memories can be altered each time they are retrieved, making them susceptible to distortion over time. |
| Retrieval is like pressing ‘play’ on a recording. | Retrieval is an active construction process that blends stored information with current expectations. |
To correct this, always remember that memory is malleable. Loftus and Palmer (1974) demonstrated how leading questions can alter recall of an event. When evaluating eyewitness testimony in WJEC, point out the reconstructive nature of memory and factors like leading questions and anxiety that reduce accuracy. Use reconstructive memory theory rather than a passive storage model.
为了纠正这一点，要始终牢记记忆是可塑的。洛夫特斯和帕尔默（1974）证明了引导性问题如何改变对事件的回忆。在WJEC中评估目击证词时，要指出记忆的重构性质以及降低准确性的因素，如引导性问题和焦虑。使用重构记忆理论而非被动的存储模型。
5. Dopamine is Simply a ‘Pleasure’ Chemical | 多巴胺只是“愉悦”化学物质
A widespread oversimplification is that dopamine is the brain’s ‘pleasure chemical’ responsible only for feelings of enjoyment. While dopamine does play a role in reward, its functions are far more complex. It is involved in motivation, movement control, learning, and even in signalling prediction errors—not just passive pleasure.
一个普遍的过度简化是，多巴胺是大脑的“愉悦化学物质”，只负责享乐的感受。虽然多巴胺确实在奖赏中发挥作用，但其功能要复杂得多。它参与动机、运动控制、学习，甚至参与预测错误的信号传递——而不仅仅是被动的愉悦。
Correcting this involves understanding the mesolimbic and mesocortical pathways. Dopamine release is associated with the anticipation of reward and the motivation to pursue goals, not simply the consumption of rewards. For example, disruptions in dopamine function are linked to Parkinson’s disease (motor symptoms) and schizophrenia (linked to dysregulated dopamine activity), which go far beyond pleasure. In AS answers, avoid the simplistic ‘pleasure’ label and refer to reward processing and motivation.
纠正这一点需要理解中脑边缘和中脑皮层通路。多巴胺的释放与奖赏预期和追求目标的动机相关，而不仅仅是奖赏的消费。例如，多巴胺功能紊乱与帕金森病（运动症状）和精神分裂症（与多巴胺活动失调有关）有关，这远远超出了愉悦的范畴。在AS答案中，避免使用简化的“愉悦”标签，应提及奖赏加工和动机。
6. Conformity is Always Negative and Undesirable | 从众总是消极且不可取的
Many students assume that conformity reflects weakness or leads to harmful outcomes, thinking of Asch’s line-judgement studies and automatically labelling conformity as negative. However, conformity serves important social functions and is not intrinsically bad. It can be driven by informational social influence, where one conforms because they believe others have more accurate knowledge in ambiguous situations.
许多学生假定从众反映了软弱或导致有害结果，想到阿希的线段判断研究就不由自主地将从众贴上消极标签。然而，从众服务于重要的社会功能，本质上并非坏事。它可能由信息性社会影响驱动，即在模糊情境中因为相信他人拥有更准确的知识而从众。
To correct this misconception, distinguish between normative influence (desire to fit in) and informational influence (desire to be right). For instance, following a crowd out of a building during a fire alarm could be lifesaving, not just mindless copying. In WJEC evaluations, acknowledge that conformity can maintain social order and help individuals learn appropriate behaviours. Conformity only becomes problematic when it leads to unethical action or suppresses individual judgement against one’s will.
要纠正这个误解，要区分规范性影响（希望合群）和信息性影响（希望正确）。例如，火警时跟随人群逃离建筑物可能挽救生命，而不仅仅是盲目模仿。在WJEC评估中，要承认从众可以维持社会秩序，并帮助个体学习适当行为。只有当从
