📚 Year 11 Eduqas Psychology: High-Frequency Topics & Common Mistakes Analysis | Year 11 Eduqas 心理学：高频考点与易错题分析
Mastering Eduqas GCSE Psychology requires more than just memorising theories; it demands a precise understanding of research methods, ethical principles, and the ability to avoid common traps. In this revision guide, we break down the high-frequency topics that appear year after year and highlight the typical mistakes candidates make, so you can secure top marks.
掌握Eduqas GCSE心理学不仅需要记忆理论，还要求精准理解研究方法、伦理原则，并能够避开常见陷阱。在这篇备考指南中，我们剖析了每年都会出现的高频考点，并指出考生常犯的典型错误，帮你锁定高分。
1. Experimental Design & Variables | 实验设计与变量控制
A frequent mistake is confusing the independent variable (IV) and the dependent variable (DV). The IV is the factor that the researcher manipulates, while the DV is the outcome measured. For example, in a study investigating whether noise affects concentration, the noise level is the IV and the number of errors on a task is the DV. Candidates often swap them when describing the aim.
常见的错误是混淆自变量(IV)和因变量(DV)。IV是研究者操纵的因素，DV是测量的结果。例如，在调查噪音是否影响注意力的研究中，噪音水平是IV，任务错误数量是DV。考生在描述研究目的时经常将它们互换。
Another high-frequency topic is experimental design: independent groups, repeated measures, and matched pairs. Students often misremember which design controls for participant variables. Use the following summary:
另一个高频考点是实验设计：独立组设计、重复测量设计和配对匹配设计。学生经常记错哪种设计控制了参与者变量。使用以下总结：
| Design / 设计 | Strengths / 优点 | Weaknesses / 缺点 | Common Mistake / 常见错误 |
|---|---|---|---|
| Independent Groups / 独立组 | No order effects / 无顺序效应 | Participant variables may bias results / 参与者变量可能干扰结果 | Assuming it eliminates participant variables / 以为它能消除参与者变量 |
| Repeated Measures / 重复测量 | Fewer participants needed; controls participant variables / 所需参与者少；控制参与者变量 | Order effects (practice, fatigue) / 顺序效应（练习、疲劳） | Forgetting to mention counterbalancing as a solution / 忘记提及平衡法作为解决方案 |
| Matched Pairs / 配对匹配 | Reduces participant variables / 减少参与者变量 | Time-consuming; difficult to match perfectly / 耗时；难以完美匹配 | Confusing with random assignment / 与随机分配相混淆 |
2. Ethics & BPS Guidelines | 研究伦理与BPS准则
Ethical considerations appear in almost every exam. Students often list ethical issues but fail to explain how to address them. The main issues are informed consent, deception, protection from harm, and confidentiality. For each, you must know at least one solution. For example, if a study uses deception, participants should be fully debriefed afterward and offered the right to withdraw data. A common mistake is writing 'debrief' without describing what it involves. Also, remember that 'consent' in school-based studies can be obtained from parents using a prior general consent form.
伦理考量几乎出现在每份试卷中。学生经常列出伦理问题，却未能解释如何处理。主要问题包括知情同意、欺骗、避免伤害和保密。对于每个问题，你必须知道至少一种解决方法。例如，如果研究使用了欺骗，应在事后对参与者进行全面任务报告并允许其撤回数据。常见错误是只写“任务报告”而不描述其内容。此外，在学校研究中，“同意”可以通过家长事先签署的一般同意书获得。
Another typical trap is mistaking anonymity for confidentiality. Anonymity means no personal records are kept at all; confidentiality means data is stored but identity is protected. Also, many candidates wrongly assume that observational studies always need informed consent—when people are in a public place where they might expect to be observed, consent may not be required.
另一个典型陷阱是将匿名与保密混淆。匿名意味着根本不保留任何个人记录；保密意味着数据被储存但身份受保护。此外，许多考生错误地认为观察研究永远需要知情同意——当人们在公共场所且可能预料到会被观察时，同意或许并非必需。
3. Biological Psychology: Neurons & Brain | 生物心理学：神经元与大脑
buttons. The direction of impulse: dendrite → cell body → axon → terminal buttons. Neurotransmitters cross the synapse, and the process involves exocytosis, receptor binding, and reuptake. A frequent error is stating that the electrical signal 'jumps' tal lobe; the visual cortex is in the occipital lobe. Confusing the locations costs marks.
神经元的结构与突触传递是必考主题。考生常错误标注树突、轴突、髓鞘和终扣。神经冲动方向：树突→细胞体→轴突→终扣。神经递质跨越突触，过程包括胞吐、与受体结合及再摄取。一个常见错误是说电信号“跳过”突触，实际上信号转换成化学信息。在大脑功能定位中，要准确：运动皮层在额叶后部，视觉皮层在枕叶。混淆位置会失分。
When explaining the role of neurotransmitters, avoid vague statements like 'serotonin makes you happy'. Instead, link specific neurotransmitters to precise functions: serotonin regulates mood, appetite, and sleep; dopamine is involved in reward and movement. A common mistake is attributing all depression to low serotonin without acknowledging the complexity of biological and environmental interactions.
在解释神经递质的作用时，避免笼统表述如“血清素让你快乐”。应把具体神经递质与确切功能联系起来：血清素调节情绪、食欲和睡眠；多巴胺参与奖励和运动。一个常见错误是把所有抑郁症都归因于血清素不足，而不承认生物与环境相互作用的复杂性。
4. Memory Models: MSM & Working Memory | 记忆模型：多存储模型与工作记忆
The multi-store model (MSM) by Atkinson and Shiffrin describes sensory register, short-term memory (STM), and long-term memory (LTM). Students must know capacity and duration for each. A typical error is stating STM duration as 18-30 seconds without specifying rehearsal can extend it. Also, many forget to mention that information is transferred from STM to LTM via maintenance
