1. Miller’s Law (Magic Number 7±2) | 米勒定律（神奇数字 7±2）
Short-term memory capacity = 7 ± 2 chunks
短时记忆容量 = 7 ± 2 个组块
George Miller (1956) discovered that the average person can hold about seven separate items in their short-term memory at once, plus or minus two. This is why we often remember 5 to 9 digits when trying to recall a random list. Miller stressed that the limit is not on bits of information, but on ‘chunks’ — meaningful units that group smaller pieces together.
George Miller（1956 年）发现，一般人的短时记忆中一次大约能保持 7 个独立的项目，上下浮动 2 个。这就是为什么我们在回忆随机列表时通常能记住 5 到 9 个数字。Miller 强调，限制不在于信息比特，而在于“组块”——将较小的信息组合在一起的意义单元。
Chunking is a strategy that increases memory efficiency. For example, the digit string ‘149217761789’ is hard to remember as 12 separate items. If you reorganise it as ‘1492 1776 1789’ (three meaningful dates), it becomes three chunks and fits neatly within the 7±2 limit. Teachers can use chunking to help students remember more in less time.
组块是一种提高记忆效率的策略。例如，数字串 “149217761789” 作为 12 个独立项目很难记。如果你将其重组为 “1492 1776 1789”（三个有意义的日期），它就变成了三个组块，恰好适应 7±2 的限制。教师可以利用组块帮助学生在更短的时间内记住更多内容。
2. Classical Conditioning (Pavlov) | 经典条件反射（巴甫洛夫）
Unconditioned stimulus (UCS) → Unconditioned response (UCR)
Neutral stimulus (NS) + UCS → UCR
Conditioned stimulus (CS) → Conditioned response (CR)
无条件刺激 (UCS) → 无条件反应 (UCR)
中性刺激 (NS) + UCS → UCR
条件刺激 (CS) → 条件反应 (CR)
Classical conditioning is a learning process where an originally neutral stimulus comes to trigger a reflex-like response after being paired with something that naturally triggers that response. Ivan Pavlov’s dogs learned to salivate to the sound of a metronome because the sound was repeatedly paired with food. This explains how many everyday associations, from fear of certain places to cravings for particular smells, are formed.
经典条件反射是一种学习过程，原本中性的刺激在与自然引发某一反应的事物配对后，最终能引发类似反射的反应。伊万·巴甫洛夫的狗学会了听到节拍器的声音就分泌唾液，因为声音反复与食物配对。这解释了许多日常联系是如何形成的，从对特定地点的恐惧到对某种气味的渴望。
The three-stage formula above is the blueprint for this learning: the UCS (food) naturally creates the UCR (salivation). When a neutral stimulus (the metronome) is presented just before the UCS several times, it becomes a conditioned stimulus (CS) that elicits the conditioned response (CR) of salivation on its own. Key features include acquisition, extinction and spontaneous recovery.
上面的三阶段公式是这种学习的蓝图：UCS（食物）自然产生 UCR（唾液分泌）。当中性刺激（节拍器）在 UCS 之前多次呈现时，它就变成了条件刺激 (CS)，能够单独引发条件反应 (CR) 即唾液分泌。关键特征包括习得、消退和自然恢复。
3. Operant Conditioning (Skinner) | 操作性条件反射（斯金纳）
Behaviour → Consequence (reinforcement or punishment) → Future behaviour probability changes
行为 → 后果（强化或惩罚） → 未来行为概率改变
B.F. Skinner showed that we learn by experiencing the consequences of our own actions. Unlike classical conditioning, which relies on existing reflexes, operant conditioning shapes voluntary behaviours through reinforcers (which increase the likelihood of a behaviour) and punishers (which decrease it). Positive means adding something; negative means taking something away.
B.F. Skinner 证明我们通过体验自身行为的后果来学习。与依赖先天反射的经典条件反射不同，操作性条件反射通过强化物（增加行为发生的可能性）和惩罚物（减少行为发生的可能性）来塑造自主行为。正强化表示增加某物；负强化表示移除某物。
The law of effect is at the heart of this model: actions followed by pleasant outcomes become stronger, while those followed by unpleasant outcomes become weaker. For instance, if a student answers a question and receives praise, they are more likely to participate again. If a child touches a hot surface and feels pain, they avoid that action in the future.
效果律是这个模型的核心：伴随愉快结果的行为会变得更强烈，而伴随不愉快结果的行为会变弱。例如，如果学生回答问题后得到表扬，他们更可能再次参与。如果孩子摸到热的表面感到疼痛，他们将来会避免该动作。
4. Social Learning Theory (Bandura) | 社会学习理论（班杜拉）
Observation → Attention → Retention → Reproduction → Motivation → Imitation
观察 → 注意 → 保持 → 再现 → 动机 → 模仿
Albert Bandura argued that we do not need direct reinforcement to learn; we can learn simply by watching others (models). In his famous Bobo doll experiment, children who observed an adult behaving aggressively towards a doll were more likely to imitate that behaviour themselves. This demonstrates that learning can occur socially, through observation and modelling.
Albert Bandura 认为我们不一定要通过直接强化来学习；我们可以仅通过观察他人（榜样）来学习。在他著名的“波波玩偶”实验中，观察到成人对玩偶的攻击性行为的儿童更可能自己模仿该行为。这表明学习可以通过社会方式、通过观察和榜样示范发生。
The formula highlights the four mediational processes: we must pay attention to the model, retain what we have seen, be physically able to reproduce the behaviour, and have the motivation — often from expecting a reward or seeing the model rewarded. This theory bridges behavioural and cognitive psychology, showing that thinking matters as much as actions.
该公式强调了四个中介过程：我们必须注意榜样，记住我们所看到的，身体上能够再现该行为，并且有动机——通常来自期待奖励或看到榜样获得奖励。这一理论连接了行为心理学和认知心理学，表明思维与行动同样重要。
5. Piaget’s Stages of Cognitive Development | 皮亚杰的认知发展阶段
Sensorimotor (0–2 years) → Preoperational (2–7 years) → Concrete operational (7–11 years) → Formal operational (11+ years)
感觉运动阶段（0–2 岁） → 前运算阶段（2–7 岁） → 具体运算阶段（7–11 岁） → 形式运算阶段（11 岁以上）
Jean Piaget proposed that children’s thinking develops in universal, invariant stages, each characterised by new logical abilities. The sensorimotor stage involves learning through senses and actions; object permanence (knowing an object still exists when out of sight) is a major achievement. In the preoperational stage, children use symbols and engage in pretend play but struggle with egocentrism and conservation tasks.
让·皮亚杰提出，儿童的思维发展遵循普遍的、不变的阶段，每个阶段都以新的逻辑能力为特征。感觉运动阶段涉及通过感官和动作学习；客体永久性（知道物体在视线之外仍存在）是一项重大成就。在前运算阶段，儿童使用符号并进行假装游戏，但难以应对自我中心和守恒任务。
During the concrete operational stage, children master conservation (understanding that quantity stays the same despite changes in shape) and can think logically about tangible objects. Finally, the formal operational stage brings abstract reasoning, hypothetical thinking and scientific problem-solving. This stage-like progression informs how teachers plan lessons appropriate to a child’s developmental level.
在具体运算阶段，儿童掌握守恒（理解无论形状如何变化数量保持不变），并能对具体物体进行逻辑思考。最后，形式运算阶段带来了抽象推理、假设性思考和科学问题解决。这种阶段式的演进指导着教师如何设计适合儿童发展水平的课程。
6. The Multi-Store Model of Memory (Atkinson & Shiffrin) | 记忆的多存储模型（阿特金森与希夫林）
Sensory register → (attention) → Short-term memory → (rehearsal) → Long-term memory
感觉登记 →（注意）→ 短时记忆 →（复述）→ 长时记忆
Atkinson and Shiffrin (1968) described memory as a linear flow of information through three separate stores. The sensory register receives a huge amount of incoming data from the senses but holds it for only a fraction of a second. If we pay attention to some of this information, it passes into short-term memory (STM), which has limited capacity and duration.
Atkinson 和 Shiffrin (1968) 将记忆描述为信息经过三个独立存储器的线性流动。感觉登记接收来自感官的大量数据，但只将其保持几分之一秒。如果我们注意到其中一些信息，它就会进入容量和持续时间都有限的短时记忆 (STM)。
Rehearsal keeps information active in STM and can transfer it into long-term memory (LTM), which is thought to have potentially unlimited capacity and can store memories for a lifetime. Forgetting occurs through decay, displacement or retrieval failure. This model explains why we must actively focus on new material and revise it repeatedly to move it from a fleeting thought to a permanent memory.
复述使信息在 STM 中保持活跃，并可将其转入长时记忆 (LTM)。长时记忆被认为具有潜在的无限容量，可终生储存记忆。遗忘是由于衰退、替代或提取失败而发生的。这个模型解释了为什么我们必须主动关注新材料并反复复习，才能将其从一闪而过的念头转变为永久记忆。
7. Yerkes-Dodson Law (Arousal and Performance) | 耶基斯–多德森定律（唤醒与表现）
Performance = f(Arousal) in an inverted-U shape
Optimal arousal level: moderate for complex tasks, higher for simple tasks
表现 = 唤醒水平的倒 U 形函数
最佳唤醒水平：复杂任务适中，简单任务较高
The Yerkes-Dodson Law states that there is an empirical relationship between arousal and performance, and it is not ‘more arousal equals better performance’. Performance improves as arousal increases but only up to an optimal point; beyond that, too much arousal leads to anxiety, stress and a drop in performance. This is often drawn as an inverted-U curve.
耶基斯–多德森定律指出，唤醒与表现之间存在经验性的关系，并不是“唤醒越多表现越好”。表现随着唤醒程度的提高而改善，但只到达一个最佳点；超过该点后，过多的唤醒会导致焦虑、压力并降低表现。这通常被绘制成倒 U 形曲线。
Task difficulty shifts the curve: for easy or well-rehearsed tasks, a higher arousal level is needed to reach peak performance; for complex tasks requiring careful thought, performance peaks at lower arousal levels. This explains why a little exam anxiety can sharpen focus, but extreme stress can cause mental blanking during a test.
任务难度会移动曲线：对于简单或熟练的任务，需要较高的唤醒水平才能达到最佳表现；对于需要仔细思考的复杂任务，表现在较低的唤醒水平下达到峰值。这解释了为什么轻微的考试焦虑能提高注意力，但极度的压力会导致考试时大脑一片空白。
8. Ekman’s Basic Emotions | 埃克曼的基本情绪
Six universal emotions: happiness, sadness, fear, anger, surprise, disgust
六种基本情绪：快乐、悲伤、恐惧、愤怒、惊讶、厌恶
Paul Ekman’s research on facial expressions identified six basic emotions that appear to be biologically hardwired and recognised across all human cultures. Even members of remote tribes with no exposure to Western media could identify these emotions from photographs, suggesting a universal, innate emotional language. This finding supports the evolutionary view that emotions help us survive and communicate.
Paul Ekman 对面部表情的研究识别出六种基本情绪，这些情绪似乎是生物学上固有的，并在所有人类文化中都能被识别。即使是未曾接触西方媒体的偏远部落成员，也能从照片中识别出这些情绪，表明存在一种普遍的、先天的情绪语言。这一发现支持了情绪帮助我们生存和沟通的进化观点。
Each emotion is associated with distinct facial muscle movements. For example, anger typically involves lowered eyebrows and glaring eyes; fear includes raised eyebrows and widened eyes. Later research has suggested a wider list including contempt, but for KS3 the core six form a reliable quick reference to understand how people express and interpret feelings without words.
每种情绪都与特定的面部肌肉运动相关。例如，愤怒通常涉及眉毛下垂和怒视；恐惧包括眉毛上扬和睁大眼睛。后来的研究提出了更广泛的清单，包括轻蔑等，但对于 KS3 来说，这六个核心情绪是理解人们如何不用语言表达和解读感受的可靠速查依据。
9. Asch Conformity (Social Influence) | 阿希从众实验（社会影响）
Conformity rate ≈ 37% when an unambiguous answer is clearly wrong but the group is unanimous
当明确答案显然错而群体一致时，从众率约 37%
Solomon Asch’s classic experiment demonstrated the power of group pressure. Participants were asked to match the length of a line with three comparison lines, a task with an obviously correct answer. When confederates (actors) unanimously gave a wrong answer, about 37% of real participants conformed and gave the same wrong answer at least once across several trials.
Solomon Asch 的经典实验证明了群体压力的力量。参与者被要求从三条比较线段中选出与标准线段长度相同的一条，该任务有明显正确的答案。当同谋者（演员）一致给出错误答案时，约 37% 的真实参与者在多次试验中至少有一次从众并给出了同样的错误答案。
This conformity was largely driven by normative social influence — the desire to fit in and avoid rejection. A second mechanism is informational social influence, where people look to the group for guidance in ambiguous situations. Asch also found that conformity dropped sharply when just one other person gave the correct answer, showing the strength of a single ally in resisting group pressure.
这种从众在很大程度上是由规范性社会影响驱动的——渴望融入群体并避免被拒绝。第二种机制是信息性社会影响，即在模糊情境中人们会向群体寻求指导。阿希还发现，只要有一人给出正确答案，从众率就会急剧下降，这表明在抵制群体压力时，一个盟友的力量是巨大的。
10. Cognitive Dissonance Theory (Festinger) | 认知失调理论（费斯汀格）
Inconsistent beliefs → psychological discomfort → attitude or behaviour change to restore consistency
不一致的信念 → 心理不适 → 改变态度或行为以恢复一致性
Leon Festinger proposed that we have a powerful drive to keep our thoughts, beliefs and behaviours consistent. When an inconsistency arises — say, believing we are healthy but smoking cigarettes — we experience cognitive dissonance, an unpleasant mental tension. This discomfort motivates us to reduce the gap, either by changing our behaviour (quitting smoking) or altering our beliefs (‘the research isn’t that convincing’).
Leon Festinger 提出，我们有强烈的驱动力去保持思想、信念和行为的一致性。当出现不一致时——例如，认为自己是健康的却吸烟——我们会体验到认知失调，一种不愉快的心理紧张。这种不适促使我们去缩小差距，要么改变行为（戒烟），要么改变信念（“研究也没那么有说服力”）。
The classic study involved participants paid either $1 or $20 to tell a lie about a boring task. Those paid only $1 later rated the task as more enjoyable because they had insufficient justification for lying and reduced dissonance by convincing themselves the task was actually interesting. Cognitive dissonance explains many everyday rationalisations, from justifying expensive purchases to sticking with poor decisions.
经典研究中，参与者被支付 1 美元或 20 美元撒谎说一项无聊的任务是有趣的。只得到 1 美元的参与者后来评价该任务更有趣，因为他们没有足够的借口说谎，于是通过说服自己任务实际上很有趣来减少失调。认知失调解释了许多日常合理化行为，从为昂贵的购买找理由到坚持糟糕的决定。
