Mastering AS AQA Psychology involves not only learning theories and studies but also actively identifying and correcting common misunderstandings that frequently appear in exam answers. These misconceptions can distort students' interpretation of research, weaken evaluation points, and lead to lost marks. This article pinpoints ten widespread pitfalls across memory, social influence, attachment, psychopathology and research methods, offering clear corrections to build accurate knowledge and boost exam confidence.
掌握 AS AQA 心理学不仅需要学习理论和研究，还要主动识别并纠正常常出现在考试答案中的常见误解。这些误解会扭曲学生对研究的解读、削弱评估论点并导致失分。本文指出记忆、社会影响、依恋、心理病理学和研究方法中的十个普遍陷阱，并提供清晰的纠正方法，以建立准确的知识并增强考试信心。
1. Short-Term Memory Capacity Is Exactly 7 Items | 短时记忆容量严格为 7 个项目
Many candidates state that short-term memory (STM) can hold exactly seven items, treating Miller's research as a fixed number.
很多考生声称短时记忆能容纳恰好 7 个项目，将米勒的研究视为一个固定数字。
Miller actually proposed a capacity of 7 ± 2 chunks, not individual items. A 'chunk' or a familiar date. This means capacity varies depending on how information is organised.
米勒实际提出的容量是 7±2 个组块，而不是单个项目。“组块”是有意义的信息组合，例如一个词或一个熟悉的日期。这意味着容量因信息的组织方式而变化。
For example, the sequence OFHUGYT can be chunked into OF, HUG, YT, reducing the memory load. Therefore, STM capacity is not a rigid limit of seven separate units.
例如，序列 OFHUGYT 可以被组块成 OF、HUG、YT，从而降低记忆负荷。因此，短时记忆容量并不是七个孤立单位的僵硬限制。
2. Long-Term Memory Is a Permanent Store | 长时记忆是永久存储
A common error is to claim that once information enters long-term memory (LTM), it remains there forever and cannot be lost.
一个常见错误是声称信息一旦进入长时记忆就会永远留在那里，不会丢失。
While LTM can have a vast duration, forgetting does occur. Two major explanations are interference (proactive and retroactive) and retrieval failure, as demonstrated by Tulving's encoding specificity principle. Information may be available but not accessible due to a lack of cues.
虽然长时记忆的持续时间可能很大，但遗忘确实会发生。两种主要解释是干扰（前摄干扰和倒摄干扰）和提取失败，如图尔文的编码特异性原则所示。信息可能因缺乏线索而“可用的”而非“可及的”。
For instance, proactive interference occurs when old learning disrupts new recall, such as remembering an old phone number instead of the current one. Thus, LTM is not immune to loss.
例如，前摄干扰指旧学习干扰新回忆，比如记住旧电话号码而不是当前号码。因此，长时记忆并不能免于丢失。
3. High Anxiety Always Impairs Eyewitness Accuracy | 高度焦虑总是损害目击者准确性
Students often assume that any increase in anxiety reduces the accuracy of eyewitness testimony, overlooking the nuanced relationship.
学生常假设焦虑的任何增加都会降低目击者证词的准确性，从而忽视了其中的微妙关系。
The Yerkes-Dodson law suggests an inverted-U relationship between arousal and performance. Moderate anxiety can actually enhance recall because attention is focused, while low or extremely high anxiety may impair memory.
耶克斯–多德森定律表明唤醒与表现之间呈倒 U 型关系。中等焦虑实际上可以增强回忆，因为注意力集中，而低度或极度焦虑则可能损害记忆。
Research by Loftus and Burns (1982) found that participants who witnessed a violent event had poorer recall for details just before the violence, supporting weapon focus. However, Christianson and Hubinette (1993) found that real witnesses to bank robberies who experienced high arousal had better recall than onlookers, showing that intense anxiety does not always produce inaccuracy.
洛夫特斯和伯恩斯（1982）的研究发现，目睹暴力事件的参与者对暴力发生前细节的回忆较差，支持武器聚焦效应。然而，克里斯蒂安森和休宾内特（1993）发现，经历过高度唤醒的真实银行抢劫案目击者比旁观者回忆得更好，表明极度焦虑并不总是导致不准确。
4. Attachment Is Formed Primarily Through Feeding | 依恋主要通过喂食形成
A classic misconception is that infants become attached to the person who feeds them, often drawing on learning theory's cupboard love explanation.
一个经典误解是婴儿会对喂食他们的人产生依恋，这常常借助学习理论中的“碗柜之爱”解释。
Harlow's (1958) research with rhesus monkeys demonstrated this is inaccurate. Infant monkeys spent most of their time clinging to a soft, cloth-covered surrogate mother that provided no food, rather than to a wire mother that provided milk. This showed that contact comfort is more crucial than feeding in forming an attachment bond.
哈洛（1958）对恒河猴的研究证明这是不准确的。幼猴大部分时间紧抱提供接触安慰的柔软绒布母猴，而非提供奶水的铁丝母猴。这表明在形成依恋纽带中，接触安慰比喂食更为关键。
Schaffer and Emerson's (1964) study on human infants also found that primary attachments were often formed with carers who were responsive and playful, not necessarily the one who fed the infant. Thus, feeding is not the foundation of attachment.
谢弗和埃默森（1964）对人类婴儿的研究也发现，最初依恋往往形成于反应迅速且爱玩的照料者，而不一定是喂食者。因此，喂食不是依恋的基础。
5. Conformity and Obedience Are the Same Process | 从众与服从是相同的过程
Many learners confuse conformity and obedience, using the terms interchangeably, which blurs crucial evaluative distinctions in AQA exam answers.
许多学习者混淆从众和服从，互换使用这两个术语，这在 AQA 考试答案中模糊了关键的评价性区别。
Conformity involves yielding to real or imagined group pressure, often resulting in a change in public behaviour but not necessarily in private beliefs (compliance). Obedience, on the other hand, involves following a direct order from an authority figure, and the individual typically perceives they have less personal responsibility.
从众涉及屈从于真实或想象中的群体压力，常导致公开行为的改变，但不一定改变私下信念（顺从）。而服从涉及遵从权威人士的直接命令，个体通常认为自己个人责任较少。
Asch's line experiment measured conformity to a unanimous but incorrect majority, while Milgram's shock study measured obedience to an experimenter's orders. These differ fundamentally in social structure and power dynamics.
阿希的线条实验测量了对一致但错误的大多数的从众，而米尔格拉姆的电击实验测量了对实验者命令的服从。两者在社会结构和权力动态上有根本区别。
6. In Asch's Study, Most Participants Never Conformed | 在阿希研究中，大多数参与者从未从众
There is a tendency to underestimate the power of conformity by thinking that the majority of participants resisted group pressure.
有一种倾向认为大多数参与者抵制了群体压力，从而低估了从众的力量。
Across all critical trials, about 75% of participants conformed at least once, while only approximately 25% never conformed at any point. Overall, the conformity rate on incorrect trials was around 37%.
在所有关键试验中，约 75% 的参与者至少从众过一次，而只有大约 25% 的人从未在任何时刻从众。总体而言，错误试次上的从众率约为 37%。
This finding is significant because it shows that normative social influence can lead ordinary people to give an obviously wrong answer. Underestimating this rate may lead to a weaker evaluation of Asch's real-world relevance.
这一发现意义重大，因为它表明规范社会影响可以导致普通人给出明显错误的答案。低估这一比率可能导致对阿希研究现实相关性的评价较弱。
7. OCD Is Simply About Compulsive Hand-Washing | 强迫症仅仅是强迫性洗手
A narrow misconception is that obsessive-compulsive disorder (OCD) is exclusively about repetitive cleaning rituals, especially hand-washing.
一个狭隘的误解是强迫症仅仅是关于重复清洁仪式，尤其是洗手。
OCD consists of two interrelated components: obsessions (persistent, intrusive, and unwanted thoughts, images, or urges) and compulsions (repetitive behaviours or mental acts performed to neutralise the anxiety produced by obsessions). Hand-washing is only one type of compulsion; others include checking, counting, or ordering.
强迫症由两个相互关联的组成部分构成：强迫思维（持久的、侵入性的、不受欢迎的想法、表象或冲动）和强迫行为（为抵消由强迫思维产生的焦虑而执行的重复行为或心理活动）。洗手只是一种强迫行为；其他还包括检查、计数或整理。
Furthermore, the cognitive approach emphasises that obsessive thoughts are misinterpreted catastrophically, turning a normal intrusive thought into a persistent source of distress. Therefore, understanding OCD requires addressing both cognitive obsessions and behavioural compulsions.
此外，认知学说强调强迫思维被灾难化地错误解读，把正常的侵入性想法变成持续的困扰来源。因此，理解强迫症需要同时处理认知上的强迫思维和行为上的强迫行为。
8. Correlation Proves Causation | 相关证明因果关系
One of the most persistent errors in research methods is stating that a significant correlation demonstrates that one variable causes the other.
研究方法中最持久的错误之一，是声称显著相关表明一个变量导致另一个变量。
A correlation coefficient (r) only indicates the strength and direction of a relationship between two co-variables. It cannot establish cause and effect because there may be a third, uncontrolled variable influencing both, or the direction of causality may be reversed.
相关系数（r）仅表明两个共变量之间关系的强度和方向。它无法确定因果关系，因为可能存在第三个不受控制的变量同时影响两者，或者因果方向可能相反。
For example, a positive correlation between ice cream sales and drowning incidents does not mean ice cream causes drowning; the hidden third variable is hot weather, which increases both swimming and ice cream consumption. Students must always note 'correlation does not imply causation' when evaluating correlational studies.
例如，冰激凌销量与溺水事件之间呈正相关，并不意味着冰激凌导致溺水；隐藏的第三变量是炎热天气，它同时增加了游泳和冰激凌消费。在评价相关研究时，学生必须始终指出“相关不意味着因果”。
9. Laboratory Experiments Are Always the Best Research Method | 实验室实验总是最佳研究方法
Due to their high internal validity, laboratory experiments are sometimes wrongly presented as the universally superior method in psychology.
由于实验室实验具有较高的内部效度，有时被错误地描述为心理学中普遍最优的方法。
While lab experiments excel in controlling extraneous variables and establishing causal relationships, they often suffer from low ecological validity and demand characteristics. Behaviours observed in an artificial setting may not generalise to real life. Furthermore, some psychological phenomena, such as long-term attachment formation or the effects of abuse, cannot ethically be manipulated in a lab.
虽然实验室实验在控制额外变量和建立因果关系方面表现出色，但它们往往生态效度低且存在需求特征。在人工环境中观察到的行为可能无法推广到现实生活。此外，某些心理现象（例如长期依恋形成或虐待的影响）在道德上不能在实验室中操控。
A balanced evaluative point should acknowledge that the choice of method depends on the research aim. Naturalistic observation, questionnaires, or interviews may be more appropriate for capturing genuine social behaviour. Therefore, no single method is 'best' for every situation.
一个平衡的评价观点应承认方法的选择取决于研究目的。自然观察、问卷或访谈可能更适合捕捉真实的社会行为。因此，没有一种单一方法对每种情况都是“最好的”。
10. Reliability and Validity Are Interchangeable Concepts | 信度和效度是可互换的概念
Students frequently confuse reliability and validity, using one term when they mean the other, which damages the precision of research method essays.
学生经常混淆信度和效度，在表达其中一个时使用另一个术语，这损害了研究方法论文的精确性。
Reliability refers to consistency: the extent to which a test or measurement produces the same result on repeated occasions (test-retest) or across different observers (inter-rater). Validity refers to accuracy: whether the tool measures what it claims to measure. A measurement can be reliable but not valid – a broken scale might always give the same weight (reliable) but the wrong weight (invalid).
信度指一致性：一个测试或测量在重复进行时（重测信度）或在不同观察者之间（评分者间信度）得出相同结果的程度。效度指准确性：工具是否测量了它声称要测量的东西。一个测量可以有信度却没效度——一把坏掉的秤可能总是给出相同的重量（有信度），但重量是错误的（无效度）。
Internal validity concerns whether observed effects are due to the manipulation of the independent variable and not confounding variables. External validity covers ecological and population generalisability. Clear separation of these concepts is essential for high-band evaluation marks in AQA AS Psychology.
内部效度关注观察到的效应是否由自变量的操纵所致，而非混淆变量。外部效度涵盖生态效度和人群推广性。清楚区分这些概念对获得 AQA AS 心理学高分评价至关重要。
