📚 Year 11 Eduqas Psychology: Common Misconceptions and Corrections | 常见误区与纠正方法
In Eduqas GCSE Psychology, students often develop misunderstandings that can hinder exam performance. This article identifies the most common misconceptions across key topics such as memory, social influence, research methods, and mental health, and provides clear corrections to strengthen your understanding.
在Eduqas GCSE心理学中，学生常产生误解，影响考试成绩。本文梳理了记忆、社会影响、研究方法和心理健康等核心主题中最常见的误区，并提供清晰纠正，以巩固你的理解。
1. Memory Works Like a Video Camera | 记忆像摄像机一样工作
Misconception: Many students believe that human memory records events accurately, like a video camera, and that memories can be played back perfectly when needed.
误区：许多学生认为人类记忆能像摄像机一样精确记录事件，需要时可以完美回放。
Correction: Memory is reconstructive. According to Bartlett's theory, memories are actively reconstructed using schemas—mental frameworks based on past experiences. Each time we recall an event, we may alter it by filling gaps with our expectations and cultural knowledge. Elizabeth Loftus later demonstrated how post-event information can change memory, making it unreliable.
纠正：记忆是重构性的。根据巴特利特的理论，记忆通过图式（基于过去经验的心理框架）主动重构。每次回忆时，我们可能用期望和文化知识填补空白，从而改变记忆。伊丽莎白·洛夫特斯后来证明，事后信息会改变记忆，使其不可靠。
Example: In Bartlett's 'War of the Ghosts' study, participants altered the story to fit their own cultural schemas, omitting unfamiliar details and adding rationalisations. This shows memory is not a passive recording.
例如：在巴特利特的“幽灵战争”研究中，参与者改变了故事以符合自己的文化图式，省略陌生细节并添加合理化内容，证明记忆不是被动记录。
Exam strategy: Always refer to reconstructive memory theory, not the 'video camera' analogy. Use key terms like 'schema', 'confabulation', and 'effort after meaning' to show understanding.
考试策略：务必引用重构记忆理论，而非“摄像机”类比。使用“图式”“虚谈”“意义追索”等关键词展示理解。
2. Short-term Memory Capacity: The Magic Number 7 | 短时记忆容量：神奇数字7
emory (STM) is 7±2 items, students assume everyone can hold exactly 7 bits of information.
误区：由于米勒提出短时记忆容量为7±2个项，学生便认为每个人都能恰好记住7条信息。
Correction: Miller's magic number refers to chunks, not raw items. By grouping information into meaningful units (chunking), we expand the effective capacity. For instance, a string of letters 'FBICIAUSA' is easier to remember when chunked as 'FBI', 'CIA', 'USA'. Additionally, Peterson and Peterson found that without rehearsal, STM duration is only about 18–30 seconds; capacity also varies with individual differences and material type.
纠正：米勒的神奇数字指的是组块，而非原始项目。通过将信息组合成有意义的单元（组块），可扩大有效容量。例如，字母串“FBICIAUSA”若组块为“FBI”“CIA”“USA”则更易记。此外，彼得森夫妇发现，若无复述，短时记忆持续时间仅约18–30秒；容量因个体差异和材料类型而异。
Key study: Peterson and Peterson (1959) used trigrams and a distractor task to prevent rehearsal, showing that STM duration is very limited. This reinforces that STM is not a static store of exactly 7 items.
关键研究：彼得森夫妇（1959）使用三字母组和干扰任务阻止复述，表明短时记忆持续时间极有限，进一步说明STM不是固定存7个项的静态仓库。
t STM always holds 7 items. Instead, describe capacity as 7±2 chunks and explain chunking.
避开陷阱：不要宣称STM总是存7个项。应描述容量为7±2个组块并解释组块现象。
3. Leading Questions and Memory Reconstruction | 引导性问题与记忆重构
Misconception: Some students think leading questions only affect the confidence of an eyewitness, not the actual memory content.
误区：有些学生认为引导性问题只影响目击者信心，不影响实际记忆内容。
Correction: Loftus and Palmer's (1974) classic experiment demonstrated that leading questions can alter a person's memory of an event. Participants who heard the verb 'smashed' estimated higher speeds and were more likely to falsely report seeing broken glass than those who heard 'hit'. This shows that post-event information becomes integrated into the original memory trace, creating a reconstructively altered memory.
纠正：洛夫特斯和帕尔默（1974）的经典实验表明，引导性问题能改变人对事件的记忆。听到“撞毁”一词的参与者估计的车速更高，且比听到“碰撞”的参与者更可能错误报告看到了碎玻璃。这表明事后信息被整合进原始记忆痕迹，形成重构后的改变。
Concept: This is known as the misinformation effect. Leading questions supply misleading post-event information, which overwrites or distorts the original memory. It is a powerful example of the reconstructive nature of memory.
概念：这就是错误信息效应。引导性问题提供了误导性事后信息，覆盖或扭曲了原始记忆。它是记忆重构性质的有力例证。
Applying knowledge: When evaluating eyewitness testimony, always discuss the misinformation effect. Mention that memory is malleable and that even subtle wording changes can implant false details.
知识应用：评价目击证词时，务必讨论错误信息效应。提及记忆是可塑的，即使是微妙的措辞变化也会植入虚假细节。
4. Conformity vs Obedience | 从众与服从的区别
Misconception: Conformity and obedience are interchangeable terms; both simply mean following others.
误区：从众与服从是可互换的术语，都指跟随他人。
Correction: Conformity is a change in behaviour or belief due to real or imagined group pressure, without a direct order. Obedience is following a direct command from an authority figure. Asch's (1951) line judgement study illustrates conformity—participants gave wrong answers to match the group even though no one ordered them. Milgram's (1963) electric shock experiment illustrates obedience—participants followed an experimenter's direct instructions despite their reluctance.
纠正：从众是由于真实或想象的群体压力而导致的行为或信念改变，无直接指令。服从是遵循权威人物的直接命令。阿希（1951）的线段判断研究展示了从众——参与者跟随群体给出错误答案，却无任何命令。米尔格拉姆（1963）的电击实验展示了服从——参与者虽不情愿，仍遵循实验者的直接指示。
Key difference: If the scenario involves a teacher, police officer, or authority figure giving a clear order, it is obedience. If it involves friends or peers pressuring someone to change their attitude or behaviour without a command, it is conformity.
关键区别：若情境涉及教师、警察或权威人物给出明确命令，则为服从。若涉及朋友或同伴施压改变态度或行为而无命令，则为从众。
Exam tip: Use appropriate terminology: normative social influence and informational social influence for conformity; agentic state and legitimate authority for obedience. Never confuse the two.
考试提示：使用适当术语：从众用规范性社会影响和信息性社会影响；服从用代理状态和合法权威。切勿混淆二者。
5. Negative Reinforcement vs Punishment | 负强化与惩罚
Misconception: Negative reinforcement is often wrongly equated with punishment, perhaps because the word 'negative' suggests something bad.
误区：负强化常被误等同于惩罚，或许因为“负”一词暗示不好的事物。
Correction: In operant conditioning, negative reinforcement increases a behaviour by removing an unpleasant stimulus. For example, taking a painkiller to relieve a headache strengthens the drug-taking behaviour. Punishment aims to decrease a behaviour by adding an aversive stimulus (positive punishment) or removing a pleasant one (negative punishment). A child being scolded for hitting stops hitting—that is punishment, as the behaviour decreases.
纠正：在操作条件反射中，负强化通过移除厌恶刺激来增加行为。例如，服用止痛药缓解头痛强化了服药行为。惩罚旨在通过添加厌恶刺激（正惩罚）或移除愉快刺激（负惩罚）来减少行为。小孩因打人受责骂而停止打人——这就是惩罚，因为行为减少了。
Memory aid: Reinforcement always strengthens a behaviour; punishment always weakens it. The terms 'positive' and 'negative' simply refer to adding or removing a stimulus.
记忆辅助：强化总是加强行为；惩罚总是削弱行为。“正”与“负”仅指添加或移除刺激。
Common exam mistakes: Saying that a detention (removing free time) is negative reinforcement. Actually, it decreases misbehaviour, so it is negative punishment. Always check the effect on behaviour.
常见考试错误：说课后留校（移除自由时间）是负强化。实际上，它减少不良行为，故为负惩罚。务必检查对行为的影响。
6. Correlation Does Not Prove Causation | 相关不等于因果
Misconception: When two variables are found to be correlated, students often conclude that one variable causes the other.
误区：当发现两个变量相关时，学生常下结论认为一个变量导致了另一个。
Correction: A correlation indicates a strength and direction of a relationship, not causation. There could be a third variable influencing both. For example, a positive correlation between ice cream sales and drowning rates does not mean ice cream causes drowning; a third variable, hot weather, increases both. In mental health research, a link between stress and depression does not prove stress causes depression—it could be that depression leads to more stress, or a biological factor underlies both.
纠正：相关性表明关系的强度和方向，而非因果。可能存在第三变量影响二者。例如，冰淇淋销量与溺水率呈正相关，并不意味冰淇淋导致溺水；第三变量炎热天气使两者都增加。在心理健康研究中，压力与抑郁相关并不能证明压力导致抑郁——可能是抑郁导致更大压力，或某个生物因素引发两者。
Why this matters: Only a well-controlled experiment with manipulation of an independent variable can suggest causality. In correlational studies, use phrases like 'associated with' or 'linked to', never 'leads to'.
为何重要：只有操纵自变量的严格实验才能暗示因果关系。在相关研究中，使用“与……相关”“有关联”等短语，切勿用“导致”。
Exam practice: When analysing data, if you spot a correlation, automatically think of alternative explanations. This will improve your evaluation marks.
