You will explore how we learn, remember, form attachments, and are influenced by others. This article summarises the core knowledge areas you will encounter, providing clear explanations and examples to support your learning.
心理学是研究人类心理和行为的科学。在 Year 7 阶段，CAIE 心理学课程带你了解一些基本概念，帮助你解释为什么人们会有不同的想法、感受和行为。你将探索我们如何学习、记忆、形成依恋关系以及如何受到他人的影响。这篇文章梳理了核心知识点，用清晰的解释和例子来辅助你的学习。
1. What Is Psychology? | 什么是心理学？
Psychology comes from Greek words meaning ‘study of the soul’. Today, it is defined as the science of behaviour and mental processes. Behaviour includes anything we do that can be observed, such as talking, running, or writing. Mental processes are internal experiences like thinking, dreaming, and remembering. Psychology uses scientific methods to study these areas, rather than relying on guesswork or common sense.
心理学一词源自古希腊语，意为“对灵魂的研究”。如今，它被定义为研究行为和心智过程的科学。行为包括我们能观察到的任何活动，比如说话、跑步或书写。心智过程则是内部的体验，如思考、做梦和记忆。心理学使用科学方法来研究这些领域，而不是依赖猜测或常识。
Psychology aims to describe, explain, predict, and sometimes change behaviour. For example, a psychologist might describe a child’s tantrum, explain why it happens, predict when it might occur again, and advise parents on how to manage it. Understanding these goals helps you see that psychology is a practical subject affecting everyday life.
心理学的目标是描述、解释、预测有时还能改变行为。比如，心理学家可能会描述孩子的发脾气行为，解释它发生的原因，预测它何时可能再次出现，并建议家长如何应对。了解这些目标有助于你认识到心理学是一门影响日常生活的实用学科。
2. Major Approaches in Psychology | 心理学的主要取向
There are several different perspectives psychologists use to understand behaviour. The biological approach focuses on the brain, hormones, and genes. For example, it might explain anxiety by looking at brain chemicals. The cognitive approach studies mental processes like memory and problem-solving. It compares the mind to a computer that processes information. The behavioural approach examines observable actions and how they are learned from the environment. The psychodynamic approach, founded by Freud, emphasises unconscious drives and childhood experiences. Although we only touch on these in Year 7, knowing these perspectives helps you see that there are many ways to explore the same question.
心理学家使用多种不同的视角来理解行为。生物学取向关注大脑、激素和基因。比如，它可能通过大脑化学物质来解释焦虑。认知取向研究记忆和解决问题等心理过程，它把人脑比作处理信息的计算机。行为主义取向研究可观察的行为以及它们如何从环境中习得。心理动力学取向由弗洛伊德创立，强调无意识驱力和童年经历。虽然在 Year 7 我们只初步接触这些，但了解它们能让你意识到探索同一个问题可以有多种方法。
In your studies, you will most frequently encounter the cognitive and behavioural approaches. For instance, when you learn about memory, you are working within a cognitive framework. When you study classical and operant conditioning, you are applying the behavioural perspective. Recognising which approach is being used gives you a deeper understanding of the research methods and explanations.
在你的学习过程中，最常接触到的是认知取向和行为主义取向。比如，当你学习记忆时，你是在认知框架下工作。当你研究经典条件反射和操作性条件反射时，你是在应用行为主义的视角。能识别出使用哪种取向，有助于你更深刻地理解研究方法和解释。
3. The Scientific Method in Psychology | 心理学中的科学方法
Psychology uses the scientific method to gather evidence. This involves forming a hypothesis, which is a testable prediction. Researchers then design a study to test the hypothesis, collect data, analyse the results, and draw conclusions. The method helps ensure that findings are based on evidence rather than personal opinions.
心理学使用科学方法来收集证据。这包括形成一个假设，即可检验的预测。研究者随后设计实验来检验假设，收集数据，分析结果并得出结论。这一方法有助于确保研究发现基于证据而不是个人观点。
You will learn about key concepts such as independent variable (the factor changed by the researcher) and dependent variable (the factor measured). For example, if a study tests whether music helps students concentrate, the independent variable is whether music is played, and the dependent variable is test scores. Understanding these terms is essential for evaluating any psychological study.
你将学习关键概念，如自变量（研究者改变的因素）和因变量（被测量的因素）。例如，如果一项研究测试音乐是否有助于学生集中注意力，自变量就是是否播放音乐，因变量则是测试成绩。理解这些术语对于评价任何心理学研究都是至关重要的。
Ethical guidelines are also introduced. Psychologists must protect participants from harm, obtain their consent, maintain confidentiality, and allow them to withdraw. These principles ensure that research is conducted responsibly.
还会介绍伦理准则。心理学家必须保护参与者免受伤害、获得他们的同意、保密并允许他们退出。这些原则确保研究以负责任的方式进行。
4. Memory: Encoding, Storage, and Retrieval | 记忆：编码、存储与提取
Memory is the process by which we retain information over time. It is often described in three stages: encoding (getting information into our memory system), storage (retaining it), and retrieval (getting it back out). Without encoding, you cannot remember anything. Paying attention is the first step in encoding.
记忆是我们随时间保留信息的过程。它通常被描述为三个阶段：编码（将信息输入记忆系统）、存储（保留信息）和提取（将信息取出）。没有编码，你就什么都记不住。集中注意力是编码的第一步。
The multi-store model of memory suggests three separate stores: sensory register, short-term memory (STM), and long-term memory (LTM). Sensory register holds information from the senses for a very brief time. If we pay attention to it, it moves to STM. STM has limited capacity (about 7±2 items) and limited duration (about 18-30 seconds without rehearsal). Rehearsal helps transfer information into LTM, which has potentially unlimited capacity and duration.
记忆的多重存储模型提出了三个独立的存储库：感觉登记、短时记忆（STM）和长时记忆（LTM）。感觉登记在极短时间内保存来自感官的信息。如果我们注意它，信息就进入 STM。STM 容量有限（约 7±2 个项目），持续时间有限（不进行复述的话大约 18-30 秒）。复述有助于把信息转移到 LTM，LTM 的容量和持续时间几乎是无限的。
You should also know that forgetting can occur at any stage. Interference, lack of cues, or simply decay over time can cause us to lose information. Year 7 students can experiment with simple memory tests to see these processes in action, such as recalling a list of words after a delay.
你还应知道，遗忘可能发生在任何阶段。干扰、缺乏线索或随时间衰退都可能导致信息丢失。Year 7 学生可以通过简单的记忆测试来观察这些过程，比如在延迟后回忆一系列单词。
5. Types of Long-Term Memory | 长时记忆的类型
Long-term memory is not a single store; psychologists distinguish between episodic memory (personal experiences), semantic memory (facts and knowledge), and procedural memory (how to do things). Episodic memory is like a mental diary; remembering your last birthday is an example. Semantic memory is like an encyclopaedia; knowing the capital of France is semantic. Procedural memory involves skills like riding a bicycle; once learned, it is often very resistant to forgetting.
长时记忆不是一个单一的存储库；心理学家区分出情节记忆（个人经历）、语义记忆（事实和知识）和程序性记忆（如何做事情）。情节记忆就像一本心理日记；记得你上次生日的情景就是一个例子。语义记忆如同百科全书；知道法国的首都是语义记忆。程序性记忆涉及像骑自行车这样的技能，一旦学会，通常很难忘记。
These categories help explain cases where people lose some types of memory but not others. For example, a person with amnesia might not remember learning a new skill (episodic) but still perform it well (procedural). Understanding these types gives you a more detailed picture of how your memory works.
这些分类有助于解释为什么有些人会丧失某些类型的记忆却保留其他类型。例如，一位患有健忘症的人可能不记得学过一项新技能（情节记忆），但仍能很好地执行它（程序性记忆）。理解这些类型能让你对记忆的运作机制有更细致的认识。
6. Learning: Classical Conditioning | 学习：经典条件反射
Classical conditioning is a type of learning discovered by Ivan Pavlov. He found that dogs could learn to associate a neutral stimulus (a bell) with food, so that eventually the bell alone made them salivate. This is called a conditioned response. The process involves an unconditioned stimulus (UCS, e.g., food) that naturally triggers an unconditioned response (UCR, salivation). After pairing a neutral stimulus (bell) with the UCS several times, the neutral stimulus becomes a conditioned stimulus (CS) that elicits a conditioned response (CR, salivation).
经典条件反射是伊万·巴甫洛夫发现的一种学习形式。他发现狗可以学会将中性刺激（铃声）与食物联系起来，以至于最终铃声单独就能使它们分泌唾液。这被称为条件反应。这一过程涉及一个自然引发无条件反应（UCR，唾液分泌）的无条件刺激（UCS，如食物）。在多次将中性刺激（铃声）与 UCS 配对后，中性刺激就变成了条件刺激（CS），它能引发条件反应（CR，唾液分泌）。
Key phenomena include extinction (the CR weakens when the CS is repeatedly presented without the UCS), spontaneous recovery (sudden reappearance of an extinguished CR), and generalisation (responding to stimuli similar to the CS). For instance, a child who was bitten by a dog may fear all dogs, not just the one that bit them.
关键现象包括消退（当 CS 反复单独出现而没有 UCS 时，CR 减弱）、自然恢复（已消退的 CR 突然再次出现）和泛化（对与 CS 相似的刺激作出反应）。例如，被狗咬过的孩子可能害怕所有的狗，而不仅仅是咬他的那只。
7. Learning: Operant Conditioning | 学习：操作性条件反射
Operant conditioning, studied by B.F. Skinner, is learning through consequences. Behaviours followed by reinforcement are more likely to be repeated, while those followed by punishment are less likely. Reinforcement can be positive (adding something pleasant, e.g., praise) or negative (removing something unpleasant, e.g., turning off a loud noise). Punishment reduces behaviour; it can also be positive (adding an unpleasant stimulus) or negative (removing a pleasant stimulus).
操作性条件反射由 B.F. 斯金纳研究，是通过后果进行学习。受到强化之后的行为更有可能被重复，而受到惩罚之后的行为则不太可能再出现。强化可以是正面的（增加愉快的事物，如表扬）或负面的（消除不愉快的事物，如关掉巨大的噪音）。惩罚减少行为；它也可以是正面的（增加不愉快刺激）或负面的（消除愉快刺激）。
A very important concept is the schedule of reinforcement. Continuous reinforcement (rewarding every time) leads to fast learning but also fast extinction. Partial reinforcement (rewarding only sometimes) leads to slower extinction and more persistent behaviour. This helps explain why some habits are hard to break—they were reinforced on an unpredictable schedule.
一个非常重要的概念是强化程式。连续强化（每次都奖励）导致学习速度快，但消退也快。部分强化（偶尔奖励）导致消退更慢，行为更持久。这有助于解释为什么有些习惯很难改掉——它们是在不可预测的程式下被强化的。
8. Social Influence: Conformity | 社会影响：从众
Conformity is when individuals change their behaviour or beliefs to fit in with a group. This can happen for two main reasons: normative social influence (wanting to be liked and accepted) and informational social influence (believing the group has more knowledge). Asch’s classic experiment showed that people often give an obviously wrong answer about line lengths simply because everyone else in the group does so.
从众是指个体改变自己的行为或信念以符合群体标准。这主要有两个原因：规范性社会影响（希望被喜欢和接纳）和信息性社会影响（认为群体掌握更多知识）。阿希的经典实验表明，人们常常仅仅因为群体中的其他人给出了错误答案，就在线长问题上给出明显错误的回答。
Factors affecting conformity include group size (conformity increases with group size up to about three or four people), unanimity (if one other person breaks the consensus, conformity drops sharply), and task difficulty (when the task is harder, people conform more). In Year 7, you can explore how peer pressure works in everyday situations, such as fashion choices or classroom behaviour.
影响从众的因素包括群体规模（群体规模增加时从众程度提高，但到三四人后趋于稳定）、一致性（如果另一个人打破了一致意见，从众程度急剧下降）和任务难度（任务越难，人们越容易从众）。在 Year 7，你可以探讨同伴压力在日常情境中如何起作用，比如时尚选择或课堂行为。
9. Social Influence: Obedience | 社会影响：服从
Obedience is following orders from an authority figure. Stanley Milgram’s famous study showed that many ordinary people would administer what they believed were dangerous electric shocks to a learner when instructed by an experimenter in a lab coat. This demonstrated the powerful effect of authority on behaviour.
服从是指遵从权威人物的命令。斯坦利·米尔格拉姆的著名研究表明，当身穿实验室白大褂的实验者发出指令时，许多普通人都会对学习者施加他们认为是危险的电击。这表明权威对行为有强大的影响力。
Factors that increase obedience include the proximity of the authority figure (closer authority increases obedience), the legitimacy of the setting (a university lab seems more legitimate), and the absence of disobedient role models. Understanding obedience helps explain historical events and everyday situations where people follow orders they might normally question.
提高服从程度的因素包括权威人物的接近性（权威越近，服从程度越高）、环境的合法性（大学实验室显得更合法）以及缺乏不服从的榜样。理解服从有助于解释历史事件以及日常生活中人们为何会遵从他们平时可能质疑的命令。
10. Attachment: Early Relationships | 依恋：早期关系
Attachment is the strong emotional bond between an infant and their primary caregiver. John Bowlby believed that attachment is innate and has survival value, as it keeps the infant close to the caregiver for protection. Mary Ainsworth identified different attachment types through the ‘Strange Situation’ experiment: secure attachment (infant explores but returns to caregiver for comfort), insecure-avoidant (infant ignores caregiver), and insecure-resistant (infant is clingy yet resists comfort).
依恋是婴儿与其主要照顾者之间强烈的情感纽带。约翰·鲍尔比认为依恋是天生的，具有生存价值，因为它让婴儿靠近照顾者以获得保护。玛丽·艾因斯沃斯通过“陌生情境”实验识别出不同的依恋类型：安全型依恋（婴儿探索环境但会回到照顾者身边寻求安慰）、不安全-回避型（婴儿忽视照顾者）和不安全-矛盾型（婴儿粘人却又拒绝安慰）。
Secure attachment is linked to healthier emotional and social development later in life. This topic also introduces the concept of deprivation and privation—loss of an existing attachment versus never forming one. Year 7 students can reflect on how early relationships might shape later friendships and self-esteem.
安全型依恋与日后更健康的情感和社会发展相关。这一主题还介绍了剥夺（丧失已有依恋）与隔绝（从未形成依恋）的概念。Year 7 学生可以思考早期关系如何塑造后来的友谊和自尊。
11. Cognitive Development: Piaget’s Theory | 认知发展：皮亚杰的理论
Jean Piaget proposed that children go through four stages of cognitive development. The sensorimotor stage (0-2 years) involves learning through senses and actions; the preoperational stage (2-7 years) is marked by egocentrism and difficulty with conservation; the concrete operational stage (7-11 years) brings logical thinking about concrete events; and the formal operational stage (11+ years) enables abstract reasoning.
让·皮亚杰提出儿童经历四个认知发展阶段。感知运动阶段（0-2 岁）通过感觉和动作来学习；前运算阶段（2-7 岁）以自我中心和守恒困难为特征；具体运算阶段（7-11 岁）能对具体事件进行逻辑思维；形式运算阶段（11 岁以上）能够进行抽象推理。
For Year 7, the focus is often on the concrete operational stage, as students themselves are transitioning toward formal operations. Understanding conservation—the idea that quantity remains the same despite changes in shape—is a classic task. For example, when water is poured from a tall, thin glass into a short, wide one, a preoperational child would say the amount has changed, while a concrete operational child recognises it is the same.
对于 Year 7，重点通常在具体运算阶段，因为学生自身正处于向形式运算过渡的时期。理解守恒——即不管形状如何变化，数量保持不变——是一个经典任务。例如，当水从一个高而细的玻璃杯倒进一个矮而宽的杯子时，前运算阶段的儿童会说水量变了，而具体运算阶段的儿童能认识到它是一样的。
12. Emotions and Basic Drives | 情绪与基本驱力
Emotions are complex states involving physiological arousal, expressive behaviours, and conscious experience. Basic emotions such as happiness, sadness, fear, anger, surprise, and disgust are thought to be universal across cultures. Psychologists have developed theories to explain how emotions arise, such as the James-Lange theory (we feel emotion after our body reacts) and the Cannon-Bard theory (emotion and bodily reaction happen simultaneously).
情绪是涉及生理唤醒、表达行为和意识体验的复杂状态。快乐、悲伤、恐惧、愤怒、惊讶和厌恶等基本情绪被认为在不同文化中具有普遍性。心理学家发展出理论来解释情绪如何产生，例如詹姆斯-兰格理论（我们体验到情绪在身体反应之后）和坎农-巴德理论（情绪和身体反应同时发生）。
Motivation involves the drives that direct behaviour toward a goal. Primary drives such as hunger and thirst are essential for survival. Our bodies maintain homeostasis—a balanced internal state. When we are hungry, a drive arises to restore balance by eating. Understanding these basic processes connects biology with psychology, showing how our physical needs influence our thoughts and actions.
动机涉及将行为导向目标的驱力。饥饿和口渴等原始驱力对生存至关重要。我们的身体维持体内平衡——一种内部平衡状态。当我们饥饿时，会产生进食以恢复平衡的驱力。理解这些基本过程将生物学与心理学联系起来，展示我们的身体需要如何影响我们的思想和行为。
