1. Memory: The Multi-Store Model | 记忆：多存储模型
Atkinson and Shiffrin (1968) proposed the Multi-Store Model of memory, which describes three distinct stores: sensory register, short-term memory (STM), and long-term memory (LTM). Information flows through these stores in a fixed sequence, and each store differs in terms of coding, capacity and duration.
Atkinson 和 Shiffrin（1968）提出了记忆的多存储模型，描述了三种独立的结构：感觉登记、短时记忆和长时记忆。信息按照固定顺序流经这些结构，每个结构在编码方式、容量和持续时间上都各不相同。
The sensory register encodes raw sensory input (iconic for visual, echoic for auditory) and holds it for less than half a second. If attention is paid, the information moves into STM, which primarily uses acoustic coding and has a limited capacity of around 7 chunks (plus or minus 2) and a duration of about 18–30 seconds without rehearsal.
感觉登记对原样的感官信息进行编码（视觉为图像记忆，听觉为声像记忆），保持时间不足半秒。若得到注意，信息便转入短时记忆，短时记忆主要采用声学编码，容量有限，约为 7±2 个组块，在不复述的情况下持续约 18–30 秒。
Maintenance rehearsal keeps information in STM, while elaborative rehearsal (making meaningful connections) is needed to transfer it into LTM. LTM is believed to have unlimited capacity and a duration that can last a lifetime; it primarily codes semantically.
保持性复述可以将信息留在短时记忆，而精细复述（建立有意义的联系）则是将信息转入长时记忆所必需的。长时记忆容量被认为是无限的，持续时间可达终生，主要以语义方式进行编码。
2. Memory: Explanations of Forgetting | 记忆：遗忘的解释
Forgetting from short-term memory is often explained by decay and displacement. Decay theory suggests memory traces fade with time if not rehearsed, while displacement occurs when new information pushes out older items from the limited-capacity STM.
短时记忆的遗忘常通过痕迹消退和位移来解释。消退理论认为，如果不进行复述，记忆痕迹会随时间消失；位移则是指新信息将旧信息从容量有限的短时记忆中挤出。
For long-term memory, interference is a major explanation for forgetting. Proactive interference happens when older memories disrupt the recall of newer information (e.g. calling your new teacher by your old teacher's name). Retroactive interference happens when newer learning impairs the recall of older memories.
对于长时记忆，干扰是遗忘的一个重要解释。前摄干扰指旧记忆扰乱新信息的提取（例如用旧老师的名字称呼新老师）；倒摄干扰则指新学习的内容损害了对旧记忆的提取。
Another explanation is retrieval failure due to the absence of cues. Context-dependent and state-dependent forgetting illustrate that recall is better when the environment or internal state matches the conditions at encoding.
另一个解释是提取失败，原因在于缺少线索。情境依赖遗忘和状态依赖遗忘说明，当提取时的环境或内部状态与编码时一致时，回忆效果更好。
3. Perception: Sensation, Visual Cues and Illusions | 感知：感觉、视觉线索与错觉
Sensation is the process of receiving raw data from the environment through sense organs, whereas perception is the brain's active process of organising and interpreting this sensory information to give it meaning. This means two people can experience the same visual input but perceive it differently.
感觉是感觉器官从环境中接收原始数据的过程，而知觉是大脑主动组织并解释这些感觉信息、赋予其意义的过程。这意味着两个人可以接收到相同的视觉输入，却产生不同的知觉。
We use monocular depth cues (such as relative size, occlusion, linear perspective and texture gradient) and binocular cues (retinal disparity and convergence) to perceive depth. Visual illusions, like the Ponzo illusion and Muller-Lyer illusion, exploit these cues to trick the brain into an incorrect perception.
我们利用单眼深度线索（如相对大小、遮挡、线条透视和纹理梯度）和双眼线索（视网膜像差和辐辏）来感知深度。视觉错觉，如庞佐错觉和缪勒-莱尔错觉，正是利用了这些线索，使大脑产生错误的知觉。
4. Perception: Gregory's Constructivist Theory vs Gibson's Direct Theory | 感知：Gregory 建构理论 vs Gibson 直接理论
Richard Gregory argued that perception is a construction process that relies heavily on past experience, expectations, and hypotheses. The brain uses stored knowledge to infer what is likely to be 'out there', making perception an active process that can sometimes lead to illusions and errors.
Richard Gregory 主张知觉是一个建构过程，高度依赖于过去的经验、预期和假设。大脑利用存储的知识来推断外界可能是什么，这使得知觉成为一个主动过程，有时会导致错觉和错误。
Eleanor Gibson, on the other hand, claimed that perception is direct and does not require inference or interpretation. Her theory emphasises that the environment provides sufficient information (such as optic flow, texture gradients, and affordances) for perception without the need for mental construction.
Eleanor Gibson 则认为知觉是直接的，不需要推论或解释。她的理论强调环境本身提供了充足的信息（如光流、纹理梯度和功能可见性），知觉无需心理建构即可完成。
Key studies such as Gibson's Visual Cliff experiment supported the idea that even young animals and infants can perceive depth without prior learning, challenging Gregorian assumptions about the role of experience.
关键研究（如 Gibson 的视崖实验）表明，即使是幼小的动物和婴儿也能在没有先前学习的情况下感知深度，这挑战了 Gregory 关于经验作用的假设。
5. Development: Piaget’s Theory of Cognitive Development | 发展：皮亚杰的认知发展理论
Jean Piaget proposed that children's thinking develops through a series of universal stages, each characterised by qualitatively different logical abilities. He believed children actively construct their own understanding through schemas, which are mental frameworks that help organise and interpret information.
让·皮亚杰提出，儿童的思维通过一系列普遍阶段发展，每个阶段具有性质不同的逻辑能力。他认为儿童通过图式（帮助组织和解释信息的心理框架）主动建构自己的理解。
The Sensorimotor stage (0–2 years) involves learning through senses and motor actions; the key achievement is object permanence. The Pre-operational stage (2–7 years) is marked by symbolic thinking, egocentrism and the inability to conserve. During the Concrete operational stage (7–11 years), children develop logical reasoning about concrete events and master conservation tasks. Finally, the Formal operational stage (12+ years) brings abstract and hypothetical thinking.
感觉运动阶段（0–2 岁）通过感官和动作学习，关键成就是客体永久性。前运算阶段（2–7 岁）以符号思维、自我中心和缺乏守恒能力为特征。具体运算阶段（7–11 岁）儿童发展出对具体事件的逻辑推理能力，掌握守恒任务。最后，形式运算阶段（12 岁以上）出现抽象和假设性思维。
Piaget's methods, such as the three-mountains task and conservation of liquid, have been criticised for cultural bias and underestimating children's abilities, yet his stage theory remains highly influential in education.
皮亚杰的方法（如三山任务和液体守恒任务）因文化偏见和低估儿童能力而受到批评，但他的阶段理论在教育领域仍然影响深远。
6. Development: Dweck’s Mindset Theory | 发展：Dweck 的心智模式理论
Carol Dweck proposed that the beliefs individuals hold about intelligence profoundly influence their motivation and achievement. A fixed mindset is the belief that intelligence is fixed and unchangeable, leading to a desire to look smart and a tendency to avoid challenges.
Carol Dweck 提出，个体对智力的看法深刻影响着他们的动机与成就。固定型心智模式认为智力是固定不变的，这会导致个体渴望表现得聪明，并倾向于回避挑战。
In contrast, a growth mindset is the belief that intelligence can grow through effort, strategies, and help from others. People with a growth mindset embrace challenges, persist in the face of setbacks, and see effort as the path to mastery.
相反，成长型心智模式相信智力可以通过努力、策略和他人的帮助得到发展。拥有成长型心态的人乐于迎接挑战，在挫折面前坚持不懈，将努力视为通往精通的路径。
Dweck’s research showed that praising students for effort rather than ability encourages a growth mindset and improves future academic resilience. These findings are widely applied in teaching to foster a 'yet' culture ('I can't do this yet').
Dweck 的研究表明，针对努力而非能力的表扬能够鼓励成长型心智模式，并增强未来的学业韧性。这些发现在教学中被广泛应用，以培养一种“尚未”文化（“我暂时还不会”）。
7. Research Methods: Experiments, Hypotheses and Variables | 研究方法：实验、假设与变量
An experiment tests cause-and-effect relationships by manipulating an independent variable (IV) and measuring the effect on a dependent variable (DV). All other extraneous variables must be controlled to prevent them from becoming confounding variables that could invalidate the results.
实验通过操纵自变量并测量其对因变量的影响来检验因果关系。所有其他额外变量都必须加以控制，以免它们成为混淆变量，导致结果无效。
Researchers formulate a hypothesis before the study. An alternative hypothesis (directional or non-directional) predicts the expected effect, while a null hypothesis states there will be no effect or difference. Hypotheses must be operationalised so variables are clearly defined and measurable.
研究者在研究前要提出假设。备择假设（方向性或非方向性）预测预期的效应，而零假设则声明不存在效应或差异。假设必须被操作化，以便变量被清晰定义并可测量。
Types of experiment include lab experiments (high control, artificial), field experiments (real-world setting, less control), and natural experiments (IV is naturally occurring, no direct manipulation). Each type has distinctive strengths and limitations regarding ecological validity and ethics.
实验类型包括实验室实验（控制度高、人为性强）、现场实验（真实环境、控制较少）和自然实验（自变量自然发生，研究者不直接操纵）。每种类型在生态效度和伦理方面都有独特的优势和局限。
8. Research Methods: Designs, Ethics and Descriptive Statistics | 研究方法：设计、伦理与描述性统计
Three classic experimental designs are used to allocate participants to conditions. An independent groups design uses different participants in each condition. A repeated measures design uses the same participants in all conditions. A matched pairs design pairs participants based on relevant characteristics and then splits them.
有三种经典的实验设计用于分配被试。独立组设计在不同条件下使用不同的被试；重复测量设计在所有条件下使用同一批被试；配对组设计则根据相关特征将被试配对，再分开安排。
Researchers must adhere to ethical guidelines including informed consent, avoidance of deception unless necessary, right to withdraw, protection from harm, and confidentiality. The BPS Code of Ethics ensures participants' wellbeing is prioritised throughout psychological research.
研究者必须遵守伦理准则，包括知情同意、避免不必要的欺骗、退出权、免受伤害以及保密。英国心理学会伦理规范确保在整个心理学研究过程中被试的福祉得到优先考量。
Once data are collected, descriptive statistics help summarise the findings. Measures of central tendency (mean, median, mode) indicate the typical score, while measures of dispersion (range, and potentially standard deviation at Year 11) show the spread. The mean is the most sensitive but can be distorted by outliers.
数据收集完毕后，描述性统计有助于总结结果。集中趋势量数（平均数、中位数、众数）代表典型分数；离散量数（全距，以及 Year 11 可能涉及的标准差）则反映数据的分布情况。平均数最为灵敏，但可能被异常值扭曲。
| Measure | Description | Key Limitation |
|---|---|---|
| Mean | Sum of scores divided by number of scores | Sensitive to extreme scores |
| Median | Middle value when ordered | Not using all data |
| Mode | Most frequent score | Possible to have more than one or none |
Range = highest score – lowest score
