📚 Common Misconceptions in Year 10 CIE Psychology and How to Correct Them | Year 10 CIE 心理学：常见误区与纠正方法
In Year 10 CIE Psychology, students often bring pre‑existing ideas about what psychology is and how the mind works. Many of these ideas are misconceptions that can lead to errors in exam answers and shallow understanding. This article identifies ten common misconceptions and explains how to correct them, using key studies and concepts from the CIE IGCSE Psychology syllabus.
在 Year 10 CIE 心理学中，学生常常带着对心理学是什么以及心智如何运作的既有观念来学习。这些观念中有许多是误区，可能导致考试答案出错和理解浮于表面。本文指出了十个常见误区，并利用 CIE IGCSE 心理学大纲中的关键研究和概念，解释了如何纠正它们。
1. Psychology is Just Common Sense | 心理学只是常识
Some students believe that psychology merely restates what we already know from everyday experience. They think psychological findings are obvious and do not require scientific investigation.
一些学生认为心理学只是在重述日常生活中已知的道理。他们认为心理学的发现都是显而易见的，不需要科学研究。
In reality, many psychological findings are counter‑intuitive and only emerge through empirical research. For example, common sense might suggest that we learn best when rewarded, but latent learning studies by Tolman showed that rats could form cognitive maps without reward, and learning was only demonstrated once a reward was introduced. Psychological science often challenges 'obvious' beliefs, such as the finding that people can be persuaded by authority figures to harm others (Milgram, 1963). This is why relying on 'common sense' alone can lead to incorrect conclusions in exams.
实际上，许多心理学发现是反直觉的，只有通过实证研究才能得出。例如，常识可能认为我们在获得奖励时学习效果最好，但托尔曼的潜伏学习研究表明，老鼠即使没有奖励也能形成认知地图，学习效果只有在引入奖励后才表现出来。心理科学经常挑战“明显”的信念，比如人们可以被权威人物说服去伤害他人（Milgram, 1963）。这就是为什么仅靠“常识”在考试中会导致错误结论。
2. We Only Use 10% of Our Brains | 我们只用了大脑的10%
The '10% of brain' myth suggests that humans only utilise a tiny fraction of their brain capacity, leaving vast potential untapped. This idea is popular in films and self‑help books.
“只用10%大脑”的迷思认为人类只利用了大脑容量的很小一部分，还有巨大的潜力未被开发。这个观点在电影和自助书籍中很流行。
Neuroimaging research, such as fMRI and PET scans, clearly shows that nearly all parts of the brain have some function. Even during sleep, brain activity is widespread. The CIE syllabus covers techniques like fMRI, which measures blood flow in the brain, demonstrating that different areas become active for different tasks. The myth likely originated from a misunderstanding of early neurological research or from the fact that glial cells outnumber neurons, but it is not supported by any modern evidence. In exams, claiming that we use only 10% of our brains would lose marks when discussing brain scanning methods or localisation of function.
神经影像学研究，如功能性磁共振成像（fMRI）和正电子发射断层扫描（PET），清楚地显示几乎所有大脑部位都有功能。即使在睡眠时，大脑活动也广泛分布。CIE 课程大纲涵盖 fMRI 等技术，这些技术测量大脑中的血流，表明不同区域在不同任务中活跃。这个迷思可能源于对早期神经学研究的误解，或者因为胶质细胞数量多于神经元，但没有任何现代证据支持。在考试中，当讨论脑部扫描方法或功能定位时，声称我们只用了10%的大脑会丢分。
3. Correlation Implies Causation | 相关意味着因果关系
When students see two variables linked by a correlation, they often jump to the conclusion that one variable causes the other. For example, 'Ice cream sales and drowning rates are positively correlated, so eating ice cream must cause drowning.'
当学生看到两个变量之间存在相关关系时，他们往往会直接得出一个变量导致另一个变量的结论。例如，“冰淇淋销量和溺水率呈正相关，所以吃冰淇淋一定导致溺水。”
A correlation only tells us that two variables are related; it does not establish cause and effect. In the ice cream example, the hidden third variable is hot weather, which increases both ice cream sales and swimming activities (and thus drownings). In IGCSE Psychology, you learn about experiments with manipulation of the independent variable and control of extraneous variables as the only way to infer causality. Correlational studies, such as those investigating the link between TV violence and aggressive behaviour, can only suggest relationships, not prove causation. Always remember the mantra: correlation does not mean causation.
相关只能告诉我们两个变量有关联，它不能建立因果关系。在冰淇淋的例子中，隐藏的第三变量是炎热天气，它既增加了冰淇淋销量，也增加了游泳活动（从而导致溺水）。在 IGCSE 心理学中，你学到通过操纵自变量并控制额外变量的实验是推断因果关系的唯一方法。相关研究，例如调查电视暴力与攻击行为之间联系的研究，只能表明存在关系，不能证明因果关系。请始终记住：相关不等于因果。
4. Memory Works Like a Video Recorder | 记忆像录像机一样工作
Many students assume that memory stores exact copies of events, and that recalling is simply replaying a recording. This leads to overestimating the accuracy of eyewitness testimony.
许多学生认为记忆储存事件的精确副本，回忆只是重放录像。这导致高估了目击者证词的准确性。
Research by Bartlett (1932) demonstrated that memory is reconstructive. When people remember a story, they often omit details, add new elements, and distort the content to fit their own schemas. Loftus and Palmer (1974) further showed that leading questions can alter memory of an event (e.g. the speed of cars in a crash). These studies are core to the CIE syllabus. Therefore, memory is more like a Wikipedia page that can be edited, not a video recorder. In your exam, you must describe these studies and explain how reconstructive memory can lead to errors, not just repeat the common misconception.
巴特利特（1932）的研究表明记忆是重构的。当人们回忆一个故事时，往往会省略细节、添加新元素，并歪曲内容以适应自己的图式。洛夫特斯和帕尔默（1974）进一步证明，引导性问题可以改变对事件的记忆（例如，撞车时汽车的速度）。这些研究是 CIE 课程大纲的核心。因此，记忆更像是可以编辑的维基百科页面，而不是录像机。在考试中，你必须描述这些研究，并解释重构记忆如何导致错误，而不能只是重复常见的误解。
5. Punishment is the Most Effective Way to Shape Behaviour | 惩罚是塑造行为最有效的方法
A common intuitive belief is that punishing unwanted behaviour is the best way to eliminate it. Parents and teachers often rely on punishment because it appears to stop misbehaviour quickly.
一种常见的直觉信念是，惩罚不良行为是消除它的最佳方法。家长和老师常常依赖惩罚，因为它似乎能迅速制止错误行为。
Operant conditioning research, particularly by Skinner, shows that while punishment can suppress behaviour temporarily, it does not teach the desired behaviour and can have negative side effects such as fear, aggression, and avoidance. Positive reinforcement (rewarding desired behaviour) is far more effective for long‑term behavioural change. Bandura's Bobo doll study also demonstrated that children imitate models, suggesting that modelling desired behaviour is more powerful than punishing undesirable actions. In the CIE exam, questions on learning theories require you to evaluate the effectiveness of reinforcement versus punishment, drawing on these classic studies.
操作性条件作用的研究，特别是斯金纳的研究，表明惩罚虽然可以暂时压制行为，但它没有教会期望的行为，并且可能带来恐惧、攻击和回避等负面副作用。正强化（奖励期望的行为）对长期行为改变有效得多。班杜拉的波波玩偶研究也证明儿童会模仿榜样，这表明示范期望行为比惩罚不良行为更有效。在 CIE 考试中，关于学习理论的题目要求你利用这些经典研究，评估强化与惩罚的有效性。
6. Experiments Always Require a Control Group | 实验总是需要对照组
Many students think that every true experiment must have a separate control group that receives no treatment. They sometimes reject valid experimental designs that lack this feature.
许多学生认为每个真正的实验都必须有一个不接受处理的单独对照组。他们有时会拒绝那些缺少这个特征的有效实验设计。
While a control condition is crucial for comparison, it does not always take the form of a separate no‑treatment group. The CIE syllabus covers three experimental designs: independent groups (where a separate control group exists), repeated measures (where the same participants serve as their own control by doing both conditions), and matched pairs (where participants are matched). In repeated measures, for instance, there is no separate control group; instead, the control condition is built into the design by comparing performance in two conditions. Understanding these designs is essential for answering questions on evaluation of methodology. So, exams require you to know that experiments need a control condition, but not necessarily a separate control group.
虽然控制条件对于比较至关重要，但它并不总是以一个单独的无处理组的形式存在。CIE 课程大纲涵盖三种实验设计：独立组（存在一个单独的对照组）、重复测量（同一组参与者通过完成两种条件来充当自己的对照）和匹配对（对参与者进行匹配）。例如，在重复测量中，没有单独的对照组；相反，控制条件是通过比较两种条件下的表现内置于设计中的。理解这些设计对于回答方法论评估的问题至关重要。因此，考试要求你了解实验需要一个控制条件，但不一定需要一个单独的对照组。
7. Brain Scans Can Read Minds | 脑部扫描可以读心
A common misconception is that brain scans, such as fMRI, allow psychologists to see exactly what a person is thinking or feeling, almost like reading their mind.
一个常见的误区是，脑部扫描，如 fMRI，可以让心理学家确切地看到一个人在想什么或感受什么，几乎像读心术一样。
Brain scans measure physiological activity (e.g. blood flow or electrical impulses) and can show which brain areas are active during certain tasks, but they cannot reveal the content of thoughts. For example, an fMRI might show that the amygdala is active when a person sees a fearful face, but it cannot tell that the person is thinking 'I am scared of snakes'. There is no one‑to‑one mapping between brain activity and specific thoughts. In CIE topics like 'Brain and Neuropsychology', students learn to interpret scanning techniques as tools for understanding localisation and brain function, not as mind‑reading devices.
脑部扫描测量的是生理活动（例如血流或电脉冲），可以显示在某些任务中大脑的哪些区域活跃，但它们不能揭示思维的内容。例如，fMRI 可能显示当一个人看到恐惧的面孔时杏仁核活跃，但它无法知道这个人在想“我怕蛇”。大脑活动与特定想法之间没有一一对应的关系。在 CIE 的“大脑与神经心理学”课题中，学生学习将扫描技术解释为理解功能定位和大脑功能的工具，而不是读心设备。
8. Naturalistic Observation is Completely Objective | 自然观察是完全客观的
When students learn about naturalistic observation as a non‑experimental method, they often assume that because the researcher does not interfere, the data collected are purely objective and free from bias.
当学生学习自然观察法作为一种非实验方法时，他们常常认为因为研究者不干预，所以收集的数据是纯粹客观的，没有偏见。
In reality, naturalistic observation is prone to observer bias—the researcher's expectations or interpretations can influence what they notice and record. For instance, if a psychologist observes playground aggression expecting boys to be more aggressive, they may unconsciously pay more attention to boys' behaviour, ignoring incidents among girls. This is why CIE expects you to discuss inter‑observer reliability (two or more observers compare records) and the use of behavioural categories to improve objectivity. No observation method is completely free from bias, and acknowledging this is
