📚 Core Concepts in Year 7 CCEA Psychology | Year 7 CCEA 心理学核心知识点梳理
Psychology is the scientific study of mind and behaviour. In Year 7, students following the CCEA specification begin to explore how we think, feel, and act. This article presents a clear and structured review of the key topics covered at this stage, including what psychology is, how research is conducted, and how we learn, remember, and interact with others. Each section pairs an English explanation with its Chinese equivalent, making it ideal for bilingual revision.
心理学是关于心智和行为的科学研究。在 Year 7，学习 CCEA 课程的学生开始探索我们如何思考、感受和行动。本文清晰、有结构地梳理了这一阶段涉及的核心主题，包括心理学的定义、研究方法，以及我们如何学习、记忆和与他人互动。每一节都提供了英文讲解和对应的中文讲解，非常适合双语复习。
1. What is Psychology? | 什么是心理学？
Psychology is the scientific study of the human mind and its functions, especially those affecting behaviour in a given context. It is not just about reading minds or treating mental disorders; it covers everything from how we perceive the world to why we form relationships. Psychologists use observation, experiments, and other methods to gather evidence and test theories about human nature.
心理学是对人类心智及其功能的科学研究，尤其关注在特定情境下影响行为的心理活动。它不仅仅是读心术或治疗心理障碍，还涉及我们如何感知世界，以及为什么我们会建立人际关系。心理学家运用观察、实验和其他方法来收集证据，并检验关于人类本性的各种理论。
The word psychology comes from the Greek words ‘psyche’ meaning soul or mind, and ‘logos’ meaning study. It therefore literally means ‘the study of the mind’. The subject bridges natural sciences and social sciences, drawing on biology, philosophy, and sociology to understand the full picture of human life.
心理学一词源自希腊语“psyche”（灵魂或心智）和“logos”（学问），因此字面意思是“研究心智的学科”。这门学科连接了自然科学与社会科学，借鉴了生物学、哲学和社会学，以全面理解人类生命。
In Year 7, you will learn that psychology is empirical, meaning it is based on evidence rather than intuition or common sense. This scientific approach helps us avoid biases and make reliable conclusions about why people do the things they do.
在 Year 7，你将了解到心理学是实证的，意味着它基于证据，而不是直觉或常识。这种科学方法帮助我们避免偏见，并得出关于人们为什么做某些事情的可靠结论。
2. Research Methods in Psychology | 心理学研究方法
Psychologists use various research methods to investigate behaviour. The main types include experiments, observations, surveys, interviews, and case studies. Experiments are particularly powerful because they allow researchers to establish cause-and-effect relationships by manipulating one variable (the independent variable) and measuring its effect on another (the dependent variable).
心理学家使用各种研究方法来探究行为。主要方法包括实验、观察、问卷调查、访谈和个案研究。实验尤其有效，因为它允许研究者通过操纵一个变量（自变量）并测量其对另一个变量（因变量）的影响，来确立因果关系。
An observation involves watching and recording behaviour in a natural or controlled setting without interference. Surveys and interviews collect self-reported data from participants about their thoughts, feelings, or behaviours. Each method has strengths and weaknesses; for example, experiments offer high control but may feel artificial, while observations capture natural behaviour but lack control over other influences.
观察法是在自然或受控环境中不加干预地观察和记录行为。问卷调查和访谈收集参与者自我报告的有关思想、感受或行为的数据。每种方法都有优点和缺点；例如，实验控制程度高但可能显得不自然，而观察法捕捉自然行为但缺乏对其他影响因素的管控。
Ethical considerations are central to psychological research. Psychologists must ensure participants give informed consent, are protected from harm, and can withdraw at any time. Deception should be avoided or minimised, and all information must remain confidential. Learning these principles early helps students appreciate the responsibility involved in studying people.
伦理考量是心理学研究的核心。心理学家必须确保参与者知情同意、免受伤害，并可以随时退出。欺骗应避免或尽量减少，所有信息必须保密。早期学习这些原则能帮助学生理解研究“人”所附有的责任。
3. Sensation and Perception | 感觉与知觉
Sensation is the process by which our sensory receptors receive and detect physical stimuli from the environment. These stimuli can be light, sound, touch, taste, or smell. Perception, on the other hand, is how our brain interprets and organises these sensory signals to give them meaning. In other words, sensation is detection, and perception is interpretation.
感觉是我们的感觉接收器接收并检测环境中物理刺激的过程。这些刺激可以是光、声、触觉、味觉或嗅觉。而知觉则是我们大脑如何解释和组织这些感觉信号以赋予其意义的过程。换句话说，感觉是检测，知觉是解释。
Our sensory systems have thresholds. The absolute threshold is the minimum amount of stimulation needed to detect a stimulus 50% of the time. For example, the absolute threshold for hearing might be the faintest sound a person can hear. The difference threshold (or just noticeable difference, JND) is the smallest change in stimulation that can be detected.
我们的感觉系统有阈值。绝对阈限是在 50% 的情况下能检测到某一刺激所需的最小刺激量。例如，听觉的绝对阈限可能是人能听到的最微弱声音。差别阈限（或最小可觉差）是能够被察觉的刺激变化的最小量。
| Sense | Absolute Threshold Example | 感觉 | 绝对阈限示例 |
| Vision | A candle flame 30 miles away on a clear night | 视觉 | 晴朗夜晚 30 英里外一支烛火 |
| Hearing | The tick of a watch at 20 feet in quiet conditions | 听觉 | 安静环境下 20 英尺外手表的滴答声 |
Perceptual illusions demonstrate that what we see or hear is not always an accurate reflection of reality. The Müller-Lyer illusion, for instance, shows that lines of equal length can appear different due to arrowhead cues, illustrating that perception is influenced by expectations and context.
知觉错觉表明，我们看到或听到的东西并不总是现实的准确反映。例如，缪勒-莱耶错觉显示，等长的线条由于箭头提示而显得不同，说明知觉受到预期和情境的影响。
4. Memory: Encoding, Storage, Retrieval | 记忆：编码、储存与提取
Memory is the process of encoding, storing, and later retrieving information. Encoding is the initial processing of information so that it can enter our memory system. Storage is the retention of that information over time. Retrieval is the process of accessing stored information when needed.
记忆是对信息进行编码、储存和之后提取的过程。编码是信息的初始处理，使其能够进入我们的记忆系统。储存是信息在时间上的保持。提取是在需要时访问储存信息的过程。
Psychologists often describe memory in terms of three stages: sensory memory, short-term memory, and long-term memory. Sensory memory briefly holds sensory information (iconic memory for images, echoic memory for sounds) for a fraction of a second. Short-term memory has a limited capacity (about 7±2 items) and duration (around 20-30 seconds) unless we actively rehearse the information.
心理学家常用三个阶段来描述记忆：感觉记忆、短时记忆和长时记忆。感觉记忆短暂地持有感觉信息（图像的感觉记忆叫图像记忆，声音的叫声像记忆），持续时间不足一秒。短时记忆容量有限（约 7±2 个组块）且持续时间短（约 20-30 秒），除非我们主动复述信息。
Long-term memory has a seemingly unlimited capacity and can store information for a lifetime. Information moves from short-term memory to long-term memory through processes such as rehearsal and meaningful association. Forgetting can occur at any stage, often due to decay, interference, or retrieval failure.
长时记忆容量似乎是无限的，可以终生储存信息。信息通过复述和意义关联等过程从短时记忆转移到长时记忆。遗忘可能发生在任何阶段，通常是由于消退、干扰或提取失败。
5. Classical Conditioning | 经典条件作用
Classical conditioning is a learning process discovered by Ivan Pavlov. It occurs when a neutral stimulus becomes associated with a stimulus that naturally produces a response. Eventually, the previously neutral stimulus alone can trigger a similar response. Pavlov famously demonstrated this with dogs: he paired the sound of a bell (neutral stimulus) with food (unconditioned stimulus), and later the bell alone caused salivation (conditioned response).
经典条件作用是伊万·巴甫洛夫发现的一种学习过程。它发生在一个中性刺激与一个自然引发某种反应的刺激形成关联时。最终，先前的中性刺激单独就能引发类似的反应。巴甫洛夫的著名实验是用狗进行的：他将铃声（中性刺激）与食物（非条件刺激）配对，后来铃声单独就能引起唾液分泌（条件反应）。
The key elements are: unconditioned stimulus (UCS) which naturally triggers a response, like food; unconditioned response (UCR) which is the natural reaction, like salivation to food; conditioned stimulus (CS) which starts neutral, like a bell; and conditioned response (CR) which is the learned response to the CS, like salivation to the bell.
关键要素包括：非条件刺激（UCS），自然引发反应，如食物；非条件反应（UCR），即自然反应，如对食物分泌唾液；条件刺激（CS），最初是中性的，如铃声；以及条件反应（CR），是对条件刺激习得的反应，如听到铃声分泌唾液。
Classical conditioning explains many everyday behaviours, such as fears and phobias, or even why certain songs make us feel a particular emotion. It also forms the basis for some therapies, such as systematic desensitisation for treating phobias.
经典条件作用解释了许多日常行为，如恐惧与恐怖症，或者为什么某些歌曲会让我们产生特定的情绪。它也为一些疗法提供了基础，例如治疗恐怖症的系统脱敏疗法。
6. Operant Conditioning | 操作条件作用
Operant conditioning, proposed by B.F. Skinner, is a type of learning in which behaviour is shaped and maintained by its consequences. If a behaviour is followed by a pleasant consequence (reinforcement), it is more likely to be repeated. If followed by an unpleasant consequence (punishment), it is less likely to be repeated.
操作条件作用由 B.F. 斯金纳提出，是一种行为受其后果塑造和维持的学习类型。如果一个行为之后伴随着愉快的后果（强化），那么该行为更可能被重复。如果伴随不愉快的后果（惩罚），则不太可能被重复。
Reinforcement can be positive (adding something desirable) or negative (removing something unpleasant). Both increase the likelihood of the behaviour. For example, giving a child a sweet for completing homework is positive reinforcement; turning off a loud alarm by pressing a button is negative reinforcement because it removes an unpleasant stimulus.
强化可以是正强化（增加令人想要的东西）或负强化（消除令人不快的东西）。两者都增加行为发生的可能性。例如，孩子完成作业后给予糖果是正强化；按下按钮关闭响亮的闹钟则是负强化，因为它消除了不愉快的刺激。
Punishment, on the other hand, aims to decrease behaviour. Positive punishment involves adding an unpleasant consequence (like scolding), while negative punishment involves removing a pleasant stimulus (like taking away a toy). Skinner’s work showed how schedules of reinforcement (fixed or variable, interval or ratio) powerfully shape behaviour patterns.
惩罚的目的是减少行为。正惩罚是施加不愉快的后果（如责骂），负惩罚是移除愉快的刺激（如拿走玩具）。斯金纳的研究表明，强化程序（固定或不固定，间隔或比率）有力地塑造了行为模式。
7. Social Influence: Conformity and Obedience | 社会影响：从众与服从
Social influence refers to the ways in which individuals change their behaviour to meet the demands of a social environment. Two key types are conformity and obedience. Conformity is adjusting one’s behaviour or thinking to match those of others, often due to real or imagined group pressure. Solomon Asch’s line experiments showed that people would give obviously wrong answers to match the group, highlighting the power of conformity.
社会影响指的是个体改变行为以适应社会环境要求的方式。两个关键类型是从众和服从。从众是指调整自己的行为或思维以配合他人，通常是由于真实的或想象中的群体压力。所罗门·阿希的线条实验表明，人们会给出明显错误的答案以迎合群体，凸显了从众的力量。
Obedience, in contrast, involves following direct orders from an authority figure. Stanley Milgram’s famous experiment on obedience revealed that ordinary people could administer what they believed were severe electric shocks to another person when instructed by an authority. This study demonstrated the potentially dangerous consequence of blindly obeying authority.
相比之下，服从是指听从权威人物的直接命令。斯坦利·米尔格拉姆著名的服从实验揭示，普通人在权威人物的指令下，可能对他人施加他们认为很严重的电击。这项研究证明了盲目服从权威的潜在危险后果。
Both conformity and obedience are influenced by situational factors like group size, unanimity, proximity of authority, and personal factors such as confidence and cultural background. Understanding these influences helps us recognise pressures in everyday situations, from peer pressure in school to organisational demands.
从众和服从都受到情境因素的影响，如群体大小、一致性、权威的接近性，以及个人因素如自信和文化背景。理解这些影响有助于我们认识日常情境中的压力，从学校同伴压力到组织要求。
8. Development: Piaget’s Stages | 发展心理学：皮亚杰的阶段论
Jean Piaget proposed a theory of cognitive development in which children pass through four distinct stages as they grow. These stages are: sensorimotor (birth to 2 years), preoperational (2 to 7 years), concrete operational (7 to 11 years), and formal operational (from 11 years onwards). Each stage is characterised by new cognitive abilities and ways of understanding the world.
让·皮亚杰提出了认知发展理论，认为儿童在成长过程中会经历四个不同的阶段。这些阶段是：感知运动阶段（出生至 2 岁）、前运算阶段（2 至 7 岁）、具体运算阶段（7 至 11 岁）和形式运算阶段（11 岁起）。每个阶段都具有新的认知能力和理解世界的方式。
In the sensorimotor stage, infants learn through their senses and actions. They develop object permanence, the understanding that objects continue to exist even when they cannot be seen. In the preoperational stage, children begin to use symbols (words and images) but are egocentric, meaning they find it difficult to see things from others’ perspectives.
在感知运动阶段，婴儿通过感官和动作学习。他们发展出客体恒存性，即理解物体即使看不见也继续存在。在前运算阶段，儿童开始使用符号（词语和图像），但以自我为中心，意味着他们难以从他人角度看问题。
By the concrete operational stage, children think logically about concrete events and can master conservation tasks (understanding that quantity remains the same despite changes in shape). Finally, in the formal operational stage, adolescents develop abstract and hypothetical reasoning, enabling them to solve complex problems and think about possibilities.
到具体运算阶段，儿童可以对具体事件进行逻辑思考，并掌握守恒任务（理解即使形状改变，数量仍保持不变）。最后，在形式运算阶段，青少年发展出抽象和假设推理能力，能够解决复杂问题并思考可能性。
9. The Brain and Nervous System | 大脑与神经系统
The nervous system is the body’s communication network, consisting of the central nervous system (CNS) – the brain and spinal cord – and the peripheral nervous system (PNS) which connects the CNS to the rest of the body. Neurons are the basic building blocks that transmit electrochemical signals rapidly, allowing us to sense, think, and move.
神经系统是人体的通讯网络，由中枢神经系统（CNS，脑和脊髓）和周围神经系统（PNS，将CNS与身体其余部分连接起来）组成。神经元是基本构建单元，能够快速传递电化学信号，使我们能感知、思考和移动。
The brain is divided into several regions with specialised functions. The frontal lobe is involved in planning, decision-making, and personality. The temporal lobe processes auditory information and plays a role in memory. The parietal lobe handles sensory information such as touch and spatial awareness, while the occipital lobe is dedicated to visual processing.
大脑分为几个具有专门功能的区域。额叶参与计划、决策和人格。颞叶处理听觉信息并在记忆中起作用。顶叶处理触觉和空间意识等感觉信息，而枕叶专门负责视觉加工。
Brain plasticity refers to the brain’s ability to change and adapt in response to experience, learning, or injury. This is especially important during childhood, but continues throughout life. Understanding how the brain works helps psychologists understand thoughts, emotions, and behaviours at a biological level.
大脑可塑性指的是大脑随经验、学习或损伤而改变和适应的能力。这在儿童期尤其重要，但会持续终生。了解大脑如何运作有助于心理学家在生物学层面理解思维、情绪和行为。
10. Emotion and Motivation | 情绪与动机
Emotions are complex psychological states that involve three components: a subjective experience (how we feel), a physiological response (such as increased heart rate), and a behavioural or expressive response (like smiling or running away). Basic emotions include happiness, sadness, fear, anger, surprise, and disgust. They help us respond quickly to situations and communicate with others.
情绪是复杂的心理状态，涉及三个成分：主观体验（我们的感受）、生理反应（如心率加快）以及行为或表达反应（如微笑或逃跑）。基本情绪包括快乐、悲伤、恐惧、愤怒、惊讶和厌恶。它们帮助我们对情境快速作出反应，并与他人沟通。
Motivation is the process that initiates, guides, and maintains goal-oriented behaviours. It can be intrinsic (driven by internal rewards like enjoyment) or extrinsic (driven by external rewards like money or praise). Theories of motivation, such as Maslow’s hierarchy of needs, suggest that basic needs like hunger and safety must be met before higher needs like belonging and self-actualisation can be pursued.
动机是引发、引导和维持目标导向行为的过程。它可以是内在的（由内部奖励驱动，如享受）或外在的（由外部奖励驱动，如金钱或表扬）。动机理论，如马斯洛的需求层次理论，指出饥饿和安全等基本需求必须先得到满足，才能追求归属和自我实现等更高需求。
In Year 7, students learn how emotions and motivation influence learning and memory. For example, we tend to remember emotionally charged events more vividly (flashbulb memories) and are more motivated to learn material that interests us personally. These insights help develop effective study strategies.
在 Year 7，学生学习情绪和动机如何影响学习和记忆。例如，我们往往更生动地记住情绪强烈的事件（闪光灯记忆），并且对个人感兴趣的材料学习动机更强。这些见解有助于制定有效的学习策略。
11. Individual Differences: Personality | 个体差异：人格
Personality refers to the unique pattern of thoughts, feelings, and behaviours that makes a person who they are. Psychologists study personality to understand why people differ from one another and how these differences can be measured. One influential model is the Big Five personality traits: openness, conscientiousness, extraversion, agreeableness, and neuroticism (OCEAN).
人格是指使一个人成为其自身的独特思维、情感和行为模式。心理学家研究人格以理解人们为何彼此不同，以及如何测量这些差异。一个有影响力的模型是大五人格特质：开放性、尽责性、外向性、宜人性和神经质（OCEAN）。
Another well-known approach is Eysenck’s three dimensions of personality: extraversion versus introversion, neuroticism versus emotional stability, and psychoticism versus impulse control. These traits are thought to have biological bases and can be assessed using self-report questionnaires. However, personality can also be shaped by life experiences and social contexts.
另一个著名的方法是艾森克的人格三维度：外向对内向、神经质对情绪稳定性、以及精神质对冲动控制。这些特质被认为有生物学基础，可使用自我报告问卷进行评估。然而，人格也可以由生活经验和社会环境塑造。
Understanding personality helps explain why people react differently to the same situation. In school settings, appreciating individual differences fosters empathy and better teamwork. It also reminds us that there is no single ‘right’ way to think or behave, highlighting the diversity of the human experience.
理解人格有助于解释为什么人们对相同情境反应不同。在学校环境中，认识个体差异可以培养同理心和更好的团队合作。它也提醒我们，没有单一的“正确”思维方式或行为方式，突显了人类经验的多样性。
