欢迎来到 TutorHao 为 Year 10 AQA GCSE 心理学准备的专项复习指南。本文聚焦于试卷一（认知与行为）中出现频率最高的课题，以及同学们在将知识应用于考题时常犯的错误。你将复习记忆模型、感知理论、认知发展、研究方法和数据处理——全部结构都有助于巩固 AO1（知识）与 AO3（评价）技能。
1. Memory: Multi-store Model | 记忆：多储存模型
The multi-store model (Atkinson & Shiffrin, 1968) describes memory as three separate stores: sensory register, short-term memory (STM), and long-term memory (LTM). Information moves from sensory register to STM only if attention is paid, and then to LTM through elaborative rehearsal.
多储存模型（Atkinson & Shiffrin, 1968）将记忆描述为三个独立的储存库：感觉登记器、短时记忆 (STM) 和长时记忆 (LTM)。信息只有在被注意时才会从感觉登记器进入 STM，再通过精细复述进入 LTM。
A frequent error is claiming that ‘rehearsal alone transfers all information to LTM’ — the model actually specifies elaborative rehearsal, which links new information to existing knowledge, while maintenance rehearsal only keeps information in STM. Also, students often forget to mention the limited capacity and duration of STM (7±2 items, 18–30 seconds) as evidence supporting the model.
一个常见的错误是声称“复述就能把全部信息转入 LTM”——模型实际上特指精细复述，即将新信息与已有知识联系，而维持性复述只能把信息保持在 STM 中。同学们还常忘记提及 STM 的有限容量和短暂持续时间（7±2 个项目，18–30 秒）作为支持模型的证据。
Key evaluation point: The case study of HM (scoville & Milner, 1957) supports the separation of STM and LTM because HM could not form new long-term memories after hippocampus removal, yet his STM remained intact. However, the model is oversimplified — it treats STM and LTM as single, unitary stores, which is contradicted by the working memory model.
关键评价点： HM 案例研究（Scoville & Milner, 1957）支持 STM 和 LTM 的分离，因为 HM 在切除海马体后无法形成新的长时记忆，但他的 STM 仍然完好。然而，该模型过于简化——它将 STM 和 LTM 视为单一的整体储存库，这与工作记忆模型相矛盾。
2. Memory: Working Memory Model | 记忆：工作记忆模型
Baddeley & Hitch (1974) proposed the working memory model as an active processing system. It includes the central executive (controls attention and coordinates slave systems), the phonological loop (deals with auditory information, subdivided into phonological store and articulatory process), the visuo-spatial sketchpad (handles visual and spatial information), and the episodic buffer (integrates information from all components into a single memory, added in 2000).
Baddeley 和 Hitch (1974) 提出了工作记忆模型，将其作为一个主动加工系统。它包括中央执行器（控制注意并协助于系统）、语音回路（处理听觉信息，又分为语音储存和发音过程）、视空间模板（处理视觉和空间信息），以及情节缓冲器（将各组成部分的信息整合为单一记忆，2000 年新增）。
A common exam mistake is muddling the functions of the phonological loop and the visuo-spatial sketchpad. Remember: phonological loop = sound-based; visuo-spatial sketchpad = vision and spatial location. Also, students frequently fail to explain the role of the episodic buffer, losing marks on both AO1 and AO3. The working memory model can explain multi-tasking (e.g., doing a visual task and a verbal task simultaneously without interference), which the multi-store model cannot.
常见的考试错误是混淆语音回路和视空间模板的功能。记住：语音回路 = 基于声音；视空间模板 = 视觉和空间位置。同学们还经常未能解释情节缓冲器的作用，在 AO1 和 AO3 上都失分。工作记忆模型可以解释多任务处理（例如，同时进行视觉任务和语言任务而不互相干扰），而多储存模型无法做到。
Use research evidence: Baddeley et al. (1975) found participants had greater difficulty performing two visual tasks than a visual and a verbal task simultaneously, supporting the separation of the sketchpad and phonological loop.
运用研究证据：Baddeley 等人 (1975) 发现，参与者同时完成两个视觉任务比同时完成一个视觉和一个语言任务困难更大，这支持了视空间模板和语音回路的分离。
3. Perception: Direct vs. Constructivist Theories | 感知：直接理论与建构主义理论
Gibson’s (1966) direct theory of perception argues that perception is innate and occurs without prior experience. The environment provides all necessary information through affordances — cues like texture gradient, optic flow, and horizon ratio that directly specify depth and distance.
Gibson (1966) 的直接感知理论认为感知是天生的，无需先前经验。环境通过“供给量”提供了所有必要信息——如纹理梯度、光流和地平线比例等线索，直接指明了深度和距离。
In contrast, Gregory’s (1970) constructivist theory claims perception is a process of inference and construction using past experience. Perception is heavily influenced by expectations, context, and stored schemas. Visual illusions occur because our brain’s hypotheses are incorrect.
相比之下，Gregory (1970) 的建构主义理论声称感知是一个利用过去经验进行推断和建构的过程。感知严重受到预期、情境和存储的图式影响。视觉错觉的产生是因为我们大脑的假设是错误的。
Common confusion: Students often state that ‘Gibson denied any role of learning’ — but Gibson acknowledged perceptual learning, he simply argued perception does not require stored representations. Also, saying ‘Gregory’s theory is wrong because illusions can be explained by the direct theory’ is poor evaluation. Instead, evaluate using cultural differences (e.g., Hudson’s 1960 study on depth perception in African tribes) which support Gregory, while the fact that newborn chicks can peck at food accurately supports Gibson.
常见混淆：同学常声称“Gibson 否认学习的任何作用”——但 Gibson 承认感知学习，他只是认为感知不需要储存的表征。此外，说“Gregory 的理论是错误的，因为错觉可以用直接理论来解释”是一种糟糕的评价。相反，应利用文化差异（如 Hudson 1960 年对非洲部落深度知觉的研究）来支持 Gregory，而刚出生的小鸡就能准确啄食这一事实则支持 Gibson。
4. Perception: Visual Illusions and Explanations | 感知：视觉错觉及其解释
The exam frequently asks for explanations of the Ponzo, Müller-Lyer, and Necker cube illusions. For the Ponzo illusion, Gregory would explain that the converging lines are interpreted as depth cues (linear perspective) causing size constancy scaling, making the upper line appear longer. Gibson would explain that the texture gradient naturally makes the upper line occupy a larger proportion of the background pattern, so it appears larger.
考试经常要求解释 Ponzo、Müller-Lyer 和 Necker 立方体错觉。对于 Ponzo 错觉，Gregory 会解释说，汇聚的线条被解读为深度线索（线性透视），引发大小恒常性缩放，使上方的线看起来更长。Gibson 则会解释，纹理梯度自然使得上方的线在背景图案中占据比例更大，因此看起来更大。
The Müller-Lyer illusion with arrowheads: the line with outward-pointing arrows looks longer. Gregory’s explanation uses misinterpretation of depth — the outward arrows resemble an inside corner of a room (farther away), so we scale it up. Students often incorrectly say ‘the line with inward arrows appears longer’; always double-check which line looks longer.
带有箭头的 Müller-Lyer 错觉：带向外箭头的线看起来更长。Gregory 的解释使用深度误读——向外的箭头类似于房间的内角（更远），因此我们将其放大。同学们常错误地说“带向内箭头的线看起来更长”；务必仔细检查哪条线看起来更长。
5. Development: Piaget’s Stages of Cognitive Development | 发展：皮亚杰认知发展阶段
Piaget proposed four stages: sensorimotor (0–2 years, object permanence), pre-operational (2–7 years, egocentrism, lack of conservation), concrete operational (7–11 years, logical reasoning about concrete events, conservation, classification), and formal operational (11+ years, abstract thinking, hypothetical-deductive reasoning).
皮亚杰提出了四个阶段：感觉运动阶段（0–2 岁，客体永久性）、前运算阶段（2–7 岁，自我中心、缺乏守恒）、具体运算阶段（7–11 岁，关于具体事件的逻辑推理、守恒、分类）和形式运算阶段（11 岁以上，抽象思维、假设演绎推理）。
Misunderstanding of ‘conservation’ is a top mistake. Conservation means understanding that quantity remains the same despite changes in appearance. In the classic conservation of liquid task, pre-operational children focus on the height of the liquid in a tall, thin glass and ignore width. Exam answers often omit the key idea of ‘centration’ (focusing on one dimension) and ‘irreversibility’ (inability to mentally reverse the process).
对“守恒”的误解是一个首要错误。守恒是指理解尽管外观改变，数量保持不变。在经典的液体守恒任务中，前运算阶段的儿童只关注高而窄的杯子中液体的高度，而忽略宽度。考试答案经常遗漏“集中化”（只关注一个维度）和“不可逆性”（无法在心理上逆转过程）这些关键概念。
For AO3, note that Piaget’s methods (e.g., the Three Mountains task for egocentrism) used complex verbal instructions, which may have underestimated younger children’s abilities. Hughes (1975) used a ‘policeman doll’ task and found much less egocentrism, demonstrating that child-friendly methods can reveal hidden competence.
对于 AO3，注意皮亚杰的方法（如用于自我中心的三山任务）使用了复杂的语言指令，可能低估了年幼儿童的能力。Hughes (1975) 使用了“警察娃娃”任务，发现自我中心少得多，这表明对儿童友好的方法能揭示隐藏的能力。
6. Development: Vygotsky and Social Development | 发展：维果茨基与社会发展
Vygotsky’s theory emphasises the role of social interaction and culture in cognitive development. Concepts include the zone of proximal development (ZPD) — the gap between what a child can do alone and what they can achieve with guidance — and scaffolding, where a more knowledgeable other (MKO) provides temporary support that is gradually withdrawn.
维果茨基的理论强调社会互动和文化在认知发展中的作用。概念包括最近发展区（ZPD）——儿童独立所能做到与在指导下所能达到之间的差距——以及支架作用，即知识更丰富的他人（MKO）提供临时支持，随后逐渐撤除。
Common exam error: students describe Vygotsky’s stages — Vygotsky did not propose fixed stages; development is continuous and varies across cultures. Also, do not confuse ZPD with IQ. Another error is failing to explicitly use the term ‘internalisation’ when referring to how language (particularly private speech) becomes inner speech to regulate thinking.
常见考试错误：同学描述维果茨基的阶段——维果茨基并未提出固定阶段；发展是连续的，且因文化而异。此外，不要将 ZPD 与智商混淆。另一个错误是，在提及语言（尤其是自言自语）如何内化为内部语言以调节思维时，未能明确使用“内化”这一术语。
A study by Conner & Cross (2003) found that mothers who gradually reduced support as children mastered tasks promoted independent problem-solving, supporting scaffolding. For balanced evaluation, note that Vygotsky’s theory may overemphasise social factors and underemphasise biological maturation.
Conner 与 Cross (2003) 的研究发现，随着儿童掌握任务，母亲逐渐减少支持，促进了独立解决问题的能力，这支持了支架作用。为了保持均衡评价，需注意维果茨基的理论可能过于强调社会因素，而低估了生理成熟的作用。
7. Research Methods: Experimental Designs | 研究方法：实验设计
The three experimental designs — independent groups, repeated measures, and matched pairs — are heavily tested. In independent groups, different participants are used in each condition. In repeated measures, the same participants do all conditions. Matched pairs involves pairing participants on a characteristic (e.g., IQ) and then splitting them, one to each condition.
三种实验设计——独立组、重复测量和配对组——都是重点考察内容。独立组设计中，每个条件下使用不同的参与者。重复测量设计中，相同的参与者完成所有条件。配对组设计则根据某一特征（如智商）将参与者配对，然后分别分配到不同条件。
A typical mistake: claiming that ‘repeated measures always has order effects’ without explaining what order effects are (practice, fatigue, boredom). You must define the term and link it to the specific study. Also, when asked to suggest an improvement, too many students write ‘use independent groups design’ without balancing the disadvantages — independent groups introduce participant variables, so you may need to use random allocation.
典型错误：声称“重复测量总是有顺序效应”，却不解释何为顺序效应（练习、疲劳、厌倦）。你必须定义该术语，并将其与具体研究联系起来。同时，当被要求提出改进建议时，很多同学写“使用独立组设计”，却不权衡其缺点——独立组设计会引入参与者变量，因此可能需要使用随机分配。
Use a table for quick revision:
| Design | Strength | Weakness |
|---|---|---|
| Independent Groups | No order effects | Participant variables |
| Repeated Measures | Controls participant variables | Order effects (counterbalancing required) |
| Matched Pairs | Reduces participant variables, no order effects | Time-consuming; imperfect matching |
8. Research Methods: Variables and Controls | 研究方法：变量与控制
You must be able to identify independent variables (IV), dependent variables (DV), and extraneous variables in any novel scenario. The IV is what you change or manipulate; the DV is what you measure. Extraneous variables are any other variables that could affect the DV if not controlled — when they do affect the DV, they become confounding variables.
你必须能够在任何新情境中识别自变量 (IV)、因变量 (DV) 和额外变量。IV 是你改变或操纵的变量；DV 是你测量的变量。额外变量是指如果不加以控制就可能影响 DV 的任何其他变量——当它们确实影响了 DV 时，它们就成为混杂变量。
A common error is stating the IV and DV as categories rather than as operationalised variables. For instance, in a study testing whether energy drinks improve memory, do not write the IV as ‘energy drink’ — write ‘whether participants drink 250 ml of an energy drink or 250 ml of water (control)’.
一个常见错误是将 IV 和 DV 表述为类别，而非操作化变量。例如，在一项测试能量饮料是否能提高记忆力的研究中，不要将 IV 写为“能量饮料”——应写为“参与者是饮用 250 毫升能量饮料还是 250 毫升水（控制条件）”。
Standardisation and randomisation are key control strategies. Confusing ‘random allocation’ with ‘random sampling’ is a frequent mistake: random allocation assigns participants to conditions within the experiment; random sampling is how you select participants from a population.
标准化和随机化是关键的控制策略。混淆“随机分配”与“随机抽样”是常见错误：随机分配是在实验内将参与者分配到不同条件；随机抽样则是你如何从总体中选取参与者的方法。
9. Research Methods: Ethical Considerations | 研究方法：伦理考量
The British Psychological Society (BPS) ethical guidelines include informed consent, right to withdraw, protection from harm, deception (usually must be avoided, if used must be justified and followed by debrief), and confidentiality. Studies like Milgram (1963) on obedience and Zimbardo’s Stanford Prison Experiment allow evaluation of ethical issues.
英国心理学会 (BPS) 的伦理指南包括知情同意、退出权、免于伤害、欺骗（通常应避免使用，如需使用必须有正当理由，并在事后进行解释简报）以及保密性。像 Milgram (1963) 的服从实验和 Zimbardo 的斯坦福监狱实验等研究，可用于对伦理问题进行评价。
Many answers lack precision: instead of saying ‘the study was unethical’, state which specific guideline was broken and how. For example, ‘Participants were not given the right to withdraw because the experimenter used verbal prods like “you have no choice, you must go on”.’ Also, note that informed consent can be challenging when the true aim is hidden — researchers may use presumptive consent or debriefing to address this.
许多答案不够精确：与其说“这项研究不道德”，不如说明违反了哪条具体指导原则以及如何违反的。例如，“参与者没有被给予退出权，因为实验者使用了‘你别无选择，必须继续’这样的言语催促。”此外，需要注意，当真实目的被隐藏时，获得知情同意可能具有挑战性——研究者可以使用假定同意或事后解释来解决此问题。
10. Data Handling: Descriptive Statistics and Graphs | 数据处理：描述统计与图表
Calculation of mean, median, mode, and range is a fundamental skill. The mean is the arithmetic average; the median is the middle value in an ordered list; the mode is the most frequent value. Students often make mistakes when computing the median for an even number of data points — you must take the mean of the two middle values.
计算平均数、中位数、众数和极差是一项基本技能。平均数是算术平均值；中位数是排序列表中的中间值；众数是出现次数最多的值。当数据点为偶数时，同学在计算中位数时经常出错——必须取两个中间值的平均数。
Choosing the correct graph type is also tested. A bar chart is used for discrete categorical data (e.g., number of participants recalling words from different lists); a histogram is for continuous data grouped into intervals; a scattergram shows correlations. Do not call a bar chart a ‘histogram’ in the exam.
选择正确的图表类型也是考查点。条形图用于离散的分类数据（例如，回忆不同词单的参与者数量）；直方图用于分组为区间的连续数据；散点图用于显示相关性。考试中不要把条形图叫作“直方图”。
Recall that a normal distribution is bell-shaped, with the mean, median, and mode at the same central point. A positively skewed distribution has a long tail to the right (mean > median > mode), and negatively skewed has a long tail to the left (mean < median < mode). Draw and label these quickly in your margin when answering questions on distributions.
记住，正态分布呈钟形，平均数、中位数和众数在同一中心点。正偏态分布右侧尾部较长（平均数 > 中位数 > 众数），负偏态分布左侧尾部较长（平均数 < 中位数 < 众数）。回答关于分布的问题时，在页边空白处快速画出并标注这些分布。
11. Common Exam Mistakes: Evaluation and AO3 Skills | 常见考试错误：评估与 AO3 技能
AO3 is worth 40% of the marks across the two papers. It requires you to evaluate theories, research, and methodologies. A generic evaluation ‘the study had a small sample size so lacks ecological validity’ will not earn many marks unless you explain why the sample is small, what specific population is unrepresented, and how this limits generalisability. Always use the ‘PEEL’ approach: Point, Evidence/Example, Explanation, Link.
AO3 在两份试卷中占 40% 的分数。它要求你评价理论、研究和方法论。泛泛地评价“该研究样本量小，因此缺乏生态效度”不会得到多少分数，除非你解释样本为什么小，哪些特定人群没有被代表，以及这如何限制了可推广性。始终使用“PEEL”方法：观点、证据/例子、解释、联系。
Another error is confusing reliability and validity. Reliability refers to consistency of measurement (e.g., test-retest, inter-rater reliability); validity refers to whether the study measures what it intends to measure (e.g., internal validity — no confounding variables; ecological validity — generalisable to real-life). Use these terms precisely.
另一个错误是混淆信度与效度。信度指测量的一致性（如重测信度、评分者间信度）；效度指该研究是否测量了其打算测量的内容（如内部效度——无混杂变量；生态效度——可推广至现实生活）。准确使用这些术语。
When asked to ‘discuss strengths and weaknesses’, aim for at least one strength and one weakness explicitly linked to the context. Do not simply list points — develop each with a clear link to the question. Questions on psychological problems (e.g., depression, addiction) often appear in mock exams; ensure you can describe characteristics and therapies using psychological terminology.
当被要求“讨论优点和弱点”时，尽量至少明确联系情境提出一个优点和一个弱点。不要只是罗列要点——每个要点都要展开，并与问题明确关联。有关心理问题（如抑郁、成瘾）的问题常出现在模拟考试中；确保你能使用心理学术语描述其特征和治疗方法。
