欢迎来到激动人心的心理学世界！本暑期衔接课程旨在帮助 Year 7 学生提前掌握 CAIE 心理学中的核心概念。心理学是关于心智和行为的科学研究，它帮助我们理解人们为什么会有特定的思考、感受和行动方式。通过本次预习，你将探索记忆、学习、情绪以及社会互动等引人入胜的话题，同时为未来的学习打下坚实的基础。
1. What Is Psychology? | 什么是心理学？
Psychology is the scientific study of mind and behaviour. It seeks to understand how we think, feel, and act both individually and in groups.
心理学是关于心智和行为的科学研究。它试图理解我们作为个体和群体如何思考、感受和行动。
Psychologists use the scientific method to gather evidence and test theories. This means that psychological knowledge is based on observable, measurable data rather than intuition alone.
心理学家运用科学方法来收集证据和检验理论。这意味着心理学知识建立在可观察、可测量的数据之上，而不仅仅是直觉。
A key goal of psychology is to describe, explain, predict, and sometimes change behaviour and mental processes. For example, educational psychologists might describe study habits, explain why some students struggle, predict who needs support, and develop interventions to help.
心理学的一个主要目标是描述、解释、预测，有时还会改变行为和心理过程。例如，教育心理学家可以描述学习习惯，解释为什么有些学生遇到困难，预测谁需要支持，并制定干预措施来提供帮助。
2. Branches of Psychology | 心理学的分支
Psychology is a broad field with many specialisations. Some major branches include cognitive psychology, which studies mental processes like memory and decision-making; developmental psychology, which focuses on human growth across the lifespan; social psychology, which examines how people influence one another; and biological psychology, which links behaviour to the brain and nervous system.
心理学是一个拥有众多分支的广阔领域。主要分支包括：认知心理学，研究记忆和决策等心理过程；发展心理学，关注人类一生的成长变化；社会心理学，探讨人们如何相互影响；以及生物心理学，将行为与大脑及神经系统联系起来。
Clinical psychology is concerned with the assessment and treatment of mental health difficulties, while industrial-organisational psychology applies psychological principles to the workplace to improve productivity and employee well-being.
临床心理学关注心理健康问题的评估与治疗，而工业与组织心理学则将心理学原理应用于工作场所，以提高生产力和员工幸福感。
Understanding these branches helps you see the many ways psychology can be applied to real-world issues, from helping people overcome anxiety to designing user-friendly technology.
了解这些分支能让你看到心理学如何应用于各种现实问题，从帮助人们克服焦虑到设计用户友好的技术。
3. Sensation and Perception | 感觉与知觉
Sensation refers to the process by which our sensory receptors detect physical energy from the environment and convert it into neural signals. Perception is the brain’s interpretation of these sensory signals, giving them meaning and organisation.
感觉是指我们的感觉感受器探测环境中的物理能量并将其转化为神经信号的过程。知觉则是大脑对这些感觉信号的解释，赋予其意义和组织。
For example, when light enters the eye, the retina senses brightness and colour (sensation). Your brain then processes this information to recognise a friend’s face (perception). Without perception, sensory input would be a confusing jumble of colours and shapes.
例如，当光线进入眼睛时，视网膜感受到亮度和颜色（感觉）。然后大脑对这些信息进行处理，识别出朋友的脸（知觉）。没有知觉，感觉输入将只是混乱的颜色和形状。
Perceptual constancies, such as size constancy and colour constancy, allow us to see objects as stable even when the sensory input changes. A door still looks rectangular even as it opens, because your brain compensates for the changing retinal image.
知觉恒常性，如大小恒常性和颜色恒常性，让我们即使感觉输入发生变化时也能将物体感知为稳定的。即使门是开着的，它看起来仍然是矩形的，因为你的大脑补偿了视网膜图像的变化。
4. Attention and Consciousness | 注意与意识
Attention is the process of selectively focusing on particular stimuli while ignoring others. It acts as a filter that prevents our cognitive systems from becoming overloaded by the vast amount of information in the environment.
注意是指选择性地专注于某些刺激而忽略其他刺激的过程。它就像一个过滤器，防止我们的认知系统被环境中大量的信息所淹没。
Selective attention can be illustrated by the ‘cocktail party effect’, where you can focus on one conversation in a noisy room but still notice if your name is called elsewhere. This shows that unattended information is processed to some extent.
选择性注意可以通过“鸡尾酒会效应”来说明，你可以在嘈杂的房间里专注于一个对话，但仍会注意到其他地方有人叫你的名字。这表明未被注意的信息在某种程度上也得到加工。
Consciousness refers to our awareness of ourselves and our environment. Different states of consciousness include wakefulness, sleep, dreaming, and daydreaming. Studying these states helps psychologists understand how the brain organises information and why we need sleep for memory consolidation.
意识是指我们对自己和环境的觉知。不同的意识状态包括清醒、睡眠、做梦和白日梦。研究这些状态有助于心理学家理解大脑如何组织信息，以及为什么我们需要睡眠来巩固记忆。
5. Memory | 记忆
Memory is the capacity to encode, store, and retrieve information. It is crucial for learning and forms the basis of our personal identity. Psychologists often describe memory in terms of three stages: sensory memory, short-term memory (STM), and long-term memory (LTM).
记忆是对信息进行编码、存储和提取的能力。它对学习至关重要，也是我们个人身份的基础。心理学家通常用三个阶段来描述记忆：感觉记忆、短时记忆（STM）和长时记忆（LTM）。
Sensory memory briefly holds sensory impressions. If you pay attention to something, it moves into STM, which has a limited capacity of about 7 ± 2 items and a duration of around 20–30 seconds without rehearsal. Rehearsing information helps transfer it into LTM, which has a virtually unlimited capacity and can last a lifetime.
感觉记忆短暂地保存感觉印象。如果你注意某事物，它就会进入短时记忆，短时记忆的容量有限，大约为 7 ± 2 个项目，如果不进行复述，持续时间约为 20–30 秒。复述信息有助于将其转入长时记忆，长时记忆的容量几乎是无限的，并且可以持续一生。
Forgetting can occur at any stage. Decay theory suggests memories fade over time, while interference theory proposes that other memories compete and disrupt recall. Using techniques like mnemonics and distributed practice can significantly improve memory retention.
遗忘可能发生在任何阶段。衰退理论认为记忆会随时间消退，而干扰理论则认为其他记忆会竞争并干扰提取。使用助记法和分散练习等技巧可以显著提高记忆的保持效果。
6. Learning | 学习
Learning is a relatively permanent change in behaviour or knowledge that results from experience. It can occur through association, consequences, and observation.
学习是由经验引起的行为或知识上相对持久的变化。它可以通过联结、后果和观察发生。
Classical conditioning, discovered by Ivan Pavlov, involves learning by association. In his famous experiment, dogs learned to salivate at the sound of a bell because the bell was repeatedly paired with food. This shows how a neutral stimulus can trigger a response after being associated with an unconditioned stimulus.
经典条件作用由伊万·巴甫洛夫发现，涉及通过联结进行学习。在他的著名实验中，狗学会在听到铃声时分泌唾液，因为铃声反复与食物配对。这表明一个中性刺激在通过与无条件刺激联结后能引发反应。
Operant conditioning, proposed by B.F. Skinner, explains how behaviour is shaped by rewards and punishments. Positive reinforcement (adding a pleasant stimulus) increases a behaviour, while punishment decreases it. For instance, a student who receives praise for homework may feel motivated to continue working hard.
操作条件作用由 B.F. 斯金纳提出，解释了行为如何受到奖励和惩罚的塑造。正强化（增加愉快刺激）会增加行为，而惩罚则会减少行为。例如，因家庭作业受到表扬的学生可能会受到激励，继续努力学习。
Observational learning, or modelling, occurs when we learn by watching others and imitating their actions. Albert Bandura’s Bobo doll study showed that children can learn aggressive behaviours simply by observing an adult acting aggressively towards a doll.
观察学习或模仿学习，是指我们通过观察他人并模仿其行为来学习。阿尔伯特·班杜拉的波波玩偶研究表明，儿童仅通过观察成人对玩偶的攻击行为就能学会攻击性行为。
7. Thinking and Problem Solving | 思维与问题解决
Thinking involves manipulating mental representations of information. It can be logical, creative, or critical. Concepts and schemas help organise our knowledge and make sense of the world.
思维涉及对信息心理表征的操作。它可以是逻辑的、创造性的或批判性的。概念和图式有助于组织我们的知识，并理解世界。
Problem solving is the process of finding a way to reach a goal when the solution is not immediately obvious. Strategies include trial and error, algorithms (step-by-step procedures), and heuristics (mental shortcuts). While heuristics are efficient, they can sometimes lead to biases like the availability heuristic, where we overestimate the likelihood of events that come easily to mind.
问题解决是在解决方案并非显而易见时找到实现目标途径的过程。策略包括试误、算法（一步步的步骤）和启发式（心理捷径）。尽管启发式效率很高，但有时也会导致偏差，比如可得性启发式，我们会高估容易想到的事件的可能性。
Creativity involves generating novel and useful ideas. Divergent thinking (brainstorming multiple possibilities) contrasts with convergent thinking (finding a single correct answer). Encouraging both types of thinking can improve learning and innovation.
创造力涉及产生新颖而有用想法的能力。发散思维（头脑风暴多种可能性）与聚合思维（寻找单一正确答案）相对。鼓励这两种思维类型可以改善学习和创新。
8. Emotion and Motivation | 情绪与动机
Emotions are complex psychological states involving physiological arousal, expressive behaviours, and conscious experience. Basic emotions such as happiness, sadness, fear, anger, surprise, and disgust appear to be universal across cultures.
情绪是复杂的心理状态，涉及生理唤醒、表达行为和意识体验。基本情绪如快乐、悲伤、恐惧、愤怒、惊讶和厌恶似乎在不同文化中普遍存在。
The James-Lange theory proposes that emotions result from our perception of bodily reactions. For example, we feel sad because we cry, rather than crying because we feel sad. In contrast, the Cannon-Bard theory argues that emotional experience and bodily reactions occur simultaneously.
詹姆斯-兰格理论认为情绪源于我们对身体反应的知觉。例如，我们感到悲伤是因为我们哭泣，而不是因为感到悲伤而哭泣。相比之下，坎农-巴德理论则认为情绪体验和身体反应同时发生。
Motivation refers to the processes that initiate, direct, and sustain goal-oriented behaviour. Intrinsic motivation comes from within (e.g., curiosity or enjoyment), while extrinsic motivation comes from external rewards (e
