📚 Common Misconceptions and Corrections in CCEA IGCSE Psychology | CCEA IGCSE 心理学常见误区与纠正方法

Many CCEA IGCSE Psychology candidates lose marks not because they lack knowledge, but because they repeat persistent misconceptions that sound plausible. This revision guide identifies the most common errors in research methods, memory, attachment, social influence and neuropsychology, and shows how to correct them with precise, exam-ready language.

许多 CCEA IGCSE 心理学考生丢分并不是因为知识不足，而是因为他们重复了一些听起来合理却持续存在的误区。本复习指南指出研究方法、记忆、依恋、社会影响和神经心理学中最常见的错误，并展示如何用准确、适合考试的表述加以纠正。

1. Correlation means causation | 相关不等于因果

A frequent error is to write that a positive correlation between two variables proves that one variable causes the other. For example, a study may show that higher screen time is correlated with lower sleep duration, and candidates then claim screen time damages sleep. This is too strong because correlation only tells us that two variables change together.

一个常见错误是写道：两个变量之间的正相关证明一个变量会导致另一个变量。例如，一项研究可能显示屏幕使用时间越长与睡眠时长越短相关，于是考生便声称屏幕使用时间损害睡眠。这种说法太强，因为相关只能说明两个变量一起变化。

The correct statement is that correlation indicates a relationship, but not causation. There could be a third variable, such as stress or evening routine, affecting both. In the CCEA exam, you should write ‘there is a positive correlation’ rather than ’causes’. If you need a causal conclusion, it must come from a well-controlled experiment, not from a correlation study.

正确的表述是：相关表明一种关系，但不表明因果。可能存在第三个变量，如压力或晚间作息，同时影响二者。在 CCEA 考试中，应写“存在正相关”而不是“导致”。如果必须得出因果结论，它应来自控制良好的实验，而不是相关研究。

In exam answers, replace ‘proves’ with ‘suggests a relationship’. If you are asked to evaluate a correlational study, state that cause-and-effect cannot be established and give a possible third variable.

在考试答案中，把“证明”替换为“表明一种关系”。如果要求评价相关研究，要说明无法确立因果关系，并给出一个可能的第三变量。

2. A hypothesis is just a guess | 假设只是猜测

Many candidates describe a hypothesis as an ‘educated guess’ and stop there. While it is a prediction, a hypothesis in psychology must be a clear, testable statement that states the expected relationship between variables. Vague phrases like ‘there will be a difference’ do not score well.

许多考生把假设描述成“有根据的猜测”就结束了。虽然假设是一种预测，但心理学中的假设必须是一个清晰、可检验的陈述，说明变量之间预期的关系。像“会有差异”这样模糊的表述得分不高。

For CCEA, an experimental hypothesis should name both conditions of the independent variable and the dependent variable. For example: ‘Participants who study with retrieval practice will recall more words than participants who re-read notes.’ The null hypothesis states no significant difference and must also be recognised.

在 CCEA 考试中，实验假设应指出自变量的两个条件以及因变量。例如：“使用提取练习的参与者比重新阅读笔记的参与者能回忆更多单词。”零假设则陈述没有显著差异，也必须能够识别。

A useful structure is: ‘There will be a difference in [DV] between [condition 1] and [condition 2].’ The alternative hypothesis can be one-tailed if the direction is predicted, or two-tailed if only a difference is expected.

一个有用的句式是：“在[条件1]和[条件2]之间，[因变量]会有差异。”如果预测了方向，备择假设可以是单尾的；如果只预期有差异，则是双尾的。

3. A larger sample always eliminates bias | 样本越大偏差越小

A common misconception is that if a sample is large, it is automatically representative, so any sampling bias disappears. In fact, a large sample can still be biased if it is drawn from a narrow group, such as only sixth-form students or only social media users.

一个常见误区是，如果样本很大，它自然就有代表性，因此任何抽样偏差都会消失。事实上，如果样本来自一个狭窄群体，比如只来自六年级学生或只来自社交媒体用户，样本再大也可能存在偏差。

The correction is that representativeness depends on the sampling method and the target population. Random sampling reduces selection bias, but does not guarantee full representativeness. Stratified sampling is better when the population has known subgroups because it ensures each subgroup is included proportionally.

纠正方法是：代表性取决于抽样方法和目标人群。随机抽样能减少选择偏差，但不保证完全具有代表性。当总体有已知的子群体时，分层抽样更好，因为它确保每个子群体按比例被纳入。

When evaluating a study, do not write ‘the sample was large, so it is unbiased’. Instead, comment on how participants were recruited and whether the sample reflects the target population in age, gender, culture or other relevant features.

在评价一项研究时，不要写“样本很大，所以没有偏差”。相反，要评论参与者是如何招募的，以及样本在年龄、性别、文化或其他相关特征上是否反映了目标总体。

4. Laboratory experiments always lack ecological validity | 实验室实验总是缺乏生态效度

Students often over-apply the criticism that lab experiments lack ecological validity. While artificial tasks and settings can reduce realism, this is not automatic. Some laboratory tasks, such as recalling a word list, resemble everyday memory use closely enough for undergraduates.

学生常常过度套用“实验室实验缺乏生态效度”这一批评。虽然人为任务和环境会降低真实性，但这不是必然的。一些实验室任务，如回忆单词表，与大学生的日常记忆使用足够相似。

The better exam answer is to say lab experiments may have lower ecological validity if the task is unlike real life, but they gain high control over extraneous variables. High control improves internal validity because the researcher can be more confident the IV caused the DV.

更好的考试答案是说：如果任务不像现实生活，实验室实验可能生态效度较低，但它们对额外变量有高度控制。高控制提高了内部效度，因为研究者更能确信是自变量导致了因变量。

Instead of always criticising ecological validity, link your evaluation to the specific task. A memory test for nonsense syllables is less realistic than recalling a story, but both can still be useful depending on the aim of the study.

与其总是批评生态效度，不如把评价与具体任务联系起来。对无意义音节的记忆测试不如回忆故事真实，但根据研究目的，两者仍然有用。

5. Memory works like a video camera | 记忆像摄像机一样工作

A very common misconception is that memory records events faithfully, like a video camera, and forgetting simply means the recording is lost. In reality, memory is reconstructive. Bartlett’s work showed that people alter memories to fit existing schemas, especially cultural expectations.

一个非常普遍的误区是，记忆像摄像机一样忠实地记录事件，遗忘仅意味着录像丢失。实际上，记忆是重构性的。巴特利特的研究表明，人们会改变记忆以符合已有的图式，尤其是文化期望。

For CCEA, you can use the War of the Ghosts study: British participants changed unfamiliar details into more familiar forms and omitted parts that did not fit their schemas. Therefore, memory is not a passive copy; it is an active reconstruction influenced by prior knowledge and expectations.

在 CCEA 中，你可以引用“鬼魂的战争”研究：英国参与者把不熟悉的细节改成更熟悉的形式，并省略不符合他们图式的部分。因此，记忆不是被动的副本；它是一种受先前知识和期望影响的主动重构。

This also explains why leading questions can distort eyewitness testimony. A question such as ‘How fast was the car going when it smashed into the other car?’ can activate a schema that makes the event seem more violent.

这也解释了为什么引导性问题会扭曲目击者证词。像“当汽车撞毁另一辆车时，速度有多快？”这样的问题会激活一个图式，使事件看起来更猛烈。

6. Attachment is formed only through feeding | 依恋只由喂养形成

Another frequent error is to state that babies attach to the person who feeds them because feeding provides pleasure. This ‘cupboard love’ view was challenged by Harlow’s monkey research and by Bowlby’s theory of attachment as an evolved emotional bond.

另一个常见错误是声称婴儿依恋喂养他们的人，因为喂养带来快乐。这种“碗柜之爱”观点遭到哈洛的猴子研究和鲍尔比把依恋视为进化情感纽带的理论的质疑。

Harlow found that infant monkeys preferred a soft cloth surrogate over a wire mother that provided food, especially when frightened. This suggests contact comfort is more important than feeding. Bowlby added that attachment has survival value and that infants form an internal working model from early care.

哈洛发现，幼猴更喜欢柔软的绒布替代母亲，而不是提供食物的铁丝母亲，尤其是在受惊时。这表明接触舒适比喂养更重要。鲍尔比补充说，依恋具有生存价值，婴儿从早期照料中形成内部工作模式。

When answering CCEA questions on attachment, avoid saying that feeding is the main cause. Instead, refer to responsive caregiving, emotional warmth and the development of a secure base from which the child can explore.

在回答 CCEA 关于依恋的问题时，不要再说喂养是主要原因。要提到回应性照料、情感温暖，以及一个儿童可以用来探索的安全基地的形成。

7. Conformity and obedience are the same | 从众与服从是同一回事

Candidates often mix up conformity and obedience in social influence questions. Conformity is changing behaviour or beliefs to match a group, often due to normative or informational pressure. Obedience is following a direct order from an authority figure, even if the action is not what the group does.

考生常常在社会影响问题中混淆从众与服从。从众是为了与群体一致而改变行为或信念，通常源于规范压力或信息压力。服从是听从权威人物的直接命令，即使该行为并不是群体在做的事。

In Asch’s line judgement study, participants conformed to the wrong majority answer even though their eyes told them the correct line. In Milgram’s shock study, participants obeyed an experimenter’s instruction to continue. The key distinction is the source of pressure: group vs authority.

在阿希的线段判断研究中，参与者屈从于多数人的错误答案，尽管他们的眼睛告诉他们正确的线段。在米尔格拉姆的电击研究中，参与者服从实验者继续下去的指示。关键区别在于压力来源：群体还是权威。

If a question asks about ‘compliance’ or ‘internalisation’, do not use them as synonyms for conformity. Compliance is public agreement without private change, while internalisation is accepting the group’s view as correct.

如果问题问的是“顺从”或“内化”，不要把它们当作从众的同义词。顺从是公开同意但没有私下改变，而内化是把群体的观点接受为正确。

8. Milgram’s participants knew the shocks were fake | 米尔格拉姆实验参与者知道电击是假的

Some students argue that Milgram’s results cannot be valid because participants probably guessed the shocks were not real. However, the original study used several realistic features: a real-looking shock generator, a rehearsed verbal protest from the learner, and an initial real 45-volt sample shock to the participant.

一些学生认为，米尔格拉姆的结果不可能有效，因为参与者可能猜到电击不是真的。然而，原始研究使用了几项逼真特征：看起来真实的电击发生器、学习者和经过排练的言语抗议，以及最初给参与者一次真实的 45 伏样本电击。

Debriefing interviews showed that many participants believed the shocks were real. However, you can still criticise demand characteristics and lack of ecological validity, but do not simply assume participants knew. The correct criticism is that the laboratory setting may have encouraged obedience rather than natural behaviour.

事后访谈显示，许多参与者相信电击是真的。不过，你仍然可以批评需求特征和生态效度不足，但不要直接假设参与者知情。正确的批评是实验室环境可能鼓励了服从，而不是自然行为。

For CCEA evaluation, use evidence such as participants sweating, trembling or asking to stop. These signs suggest genuine distress and support the claim that many believed the situation was real.

在 CCEA 评价中，使用参与者出汗、发抖或要求停止等证据。这些迹象表明真实的痛苦，并支持许多参与者相信情境是真实的这一说法。

9. Ethics only matters after data collection | 伦理只在数据收集后才重要

A common misconception is that ethical issues in psychology are only about what happens after a study, such as debriefing. In fact, ethical thinking must occur before, during and after data collection. Researchers must gain informed consent, protect participants from harm, and ensure confidentiality throughout.

一个常见误区是，心理学中的伦理问题只与研究结束后发生的事情有关，比如事后解释。事实上，伦理考量必须贯穿数据收集之前、期间和之后。研究者必须获得知情同意，保护参与者免受伤害，并全程确保保密。

For CCEA, you should be able to apply the BPS ethical guidelines: consent, deception, debriefing, right to withdraw, confidentiality, and protection from harm. If a study uses deception, it must be justified and followed by a full debrief. Ethical issues can also arise from the way data are stored and shared.

在 CCEA 中，你应该能够应用 BPS 伦理准则：同意、欺骗、事后解释、退出权、保密和免受伤害。如果研究使用欺骗，它必须有正当理由，并在之后进行充分的事后解释。数据存储和共享方式也可能引发伦理问题。

When evaluating a study, do not just write ‘it was unethical’. Identify which guideline was broken, explain how it could affect participants, and suggest a practical improvement such as giving a full debrief or ensuring the right to withdraw.

在评价一项研究时，不要只写“这是不道德的”。要指出违反了哪条准则，解释它会如何影响参与者，并提出实际改进，例如给予充分的事后解释或确保退出权。

10. Nature and nurture act separately | 先天与后天各自独立作用

In debates such as intelligence or aggression, students often treat nature and nurture as two separate boxes and ask which one is more important. Modern psychology accepts that they interact. Genes may provide a potential range, but the environment influences whether certain genetic tendencies are expressed.

在智力或攻击性等争论中，学生常常把先天和后天当作两个独立的盒子，并问哪一个更重要。现代心理学认为二者是相互作用的。基因提供了一个可能范围，但环境会影响某些遗传倾向是否表现出来。

For example, a child may inherit a genetic vulnerability to anxiety, but whether it develops into a disorder may depend on stressors, parenting and social support. In CCEA answers, use the term ‘interactionist approach’ and give an example that shows both factors working together.

例如，一个孩子可能遗传了对焦虑的易感性，但它是否会发展成障碍可能取决于压力源、养育方式和社会支持。在 CCEA 答案中，使用“交互作用取向”这一术语，并给出一个显示两种因素共同作用的例子。
