📚 Year 7 SQA Psychology: Core Knowledge Review | Year 7 SQA 心理学：核心知识点梳理
Psychology is the fascinating scientific study of how we think, feel and behave. In Year 7, according to the SQA framework in Scotland, you begin your journey by exploring key topics that explain human experience — from memory and attachment to social influence and brain basics. This article brings together all the essential knowledge you need, presented in clear bilingual sections to support your learning and revision.
心理学是一门引人入胜的科学，研究我们如何思考、感受和行动。根据苏格兰 SQA 课程框架，七年级是你探索心理学的起点，你会接触到记忆、依恋、社会影响以及大脑基础等核心主题。这篇文章为你梳理了所有必须掌握的知识点，以清晰的中英双语段落呈现，帮助你学习和复习。
1. What is Psychology? | 什么是心理学？
Psychology is defined as the scientific study of mind and behaviour. The term comes from the Greek words ‘psyche’ (meaning soul or mind) and ‘logos’ (meaning study). Unlike everyday guesses about why people act in certain ways, psychology uses systematic methods to observe, measure and explain thoughts and actions. It covers everything from how we learn language to why we experience emotions like fear and joy. Psychologists work in many areas, including clinical settings, schools, businesses and research laboratories, all aiming to understand and improve human life.
心理学被定义为对心智和行为的科学研究。这个词来源于希腊语 ‘psyche’（意为灵魂或心智）和 ‘logos’（意为研究）。与日常对人们行为的猜测不同，心理学使用系统的方法来观察、测量和解释思维与行动。它涵盖了从我们如何学习语言到为什么我们会经历恐惧和喜悦等情感的广阔领域。心理学家在许多领域工作，包括临床环境、学校、企业和研究实验室，他们的目标都是理解并改善人类生活。
One of the great strengths of psychology is its varied perspectives. The biological perspective looks at the role of genes, hormones and the brain. The cognitive perspective examines mental processes such as memory and problem-solving. The behavioural perspective focuses on how we learn from the environment through conditioning. Finally, the sociocultural perspective considers how other people and cultural norms shape our behaviour. In Year 7, you gain a taste of each of these approaches.
心理学的一大优势在于它多元的视角。生物学视角关注基因、激素和大脑的作用。认知视角考察记忆和问题解决等心理过程。行为主义视角专注于我们如何通过条件反射从环境中学习。最后，社会文化视角则思考他人和文化规范如何塑造我们的行为。在七年级，你将初步体验每一种取向。
2. The Scientific Approach in Psychology | 心理学中的科学方法
Psychology is a science because it follows the empirical method. This means psychologists do not simply rely on intuition; they collect data through careful observation, experiments and surveys. A typical research process begins with a question, followed by a hypothesis — a testable prediction. Researchers then design a study, gather evidence and analyse results to see whether the hypothesis is supported. Crucially, findings must be checked for reliability (can the results be repeated?) and validity (does the study measure what it claims to measure?).
心理学之所以是一门科学，是因为它遵循实证方法。这意味着心理学家不单凭直觉行事，而是通过细致的观察、实验和问卷调查来收集数据。典型的研究过程始于一个问题，接着提出假设——一个可检验的预测。研究人员随后设计研究方案，收集证据并分析结果，以检验假设是否得到支持。关键的是，研究结果必须经过信度（结果能够被重复吗？）和效度（研究测量的是它声称要测量的东西吗？）的检验。
You will also learn about ethical guidelines that protect participants in psychological research. In the UK, the British Psychological Society (BPS) sets rules such as obtaining informed consent, avoiding deception unless absolutely necessary, ensuring confidentiality and allowing participants to withdraw at any time. These principles are especially important when working with children and vulnerable people, and they remind us that the pursuit of knowledge must never harm the people we study.
你还会学到保护心理学研究参与者的伦理准则。在英国，英国心理学会（BPS）制定了一系列规则，例如获得知情同意、除非绝对必要否则避免欺骗、确保保密性以及允许参与者随时退出研究。这些原则在与儿童和弱势群体合作时尤为重要，它们提醒我们，对知识的追求绝不能伤害我们研究的人。
3. Memory: Encoding, Storage and Retrieval | 记忆：编码、存储与提取
Memory is the process by which we encode, store and later retrieve information. Think of memory like a computer: information first comes in through our senses, is turned into a code that the brain can use (encoding), then kept in storage for different lengths of time, and finally brought back when needed (retrieval). Understanding these stages helps explain why we sometimes forget a name or why certain memories last a lifetime.
记忆是我们编码、存储和之后提取信息的过程。你可以把记忆想象成一台电脑：信息首先通过感官进入，转化成大脑能使用的代码（编码），然后在存储系统中保存不同时长，最后在需要时被调出来（提取）。理解这些阶段有助于解释为什么我们有时会忘记一个名字，或者为什么某些记忆能持续一生。
Psychologists often describe three types of memory stores. Sensory memory holds sensory information for a fraction of a second, just long enough to decide what to pay attention to. Short-term memory (STM) can hold about 5–9 items for around 15–30 seconds, but this can be extended through rehearsal. Long-term memory (LTM) has a potentially unlimited capacity and can store information for minutes to a lifetime. Information moves into LTM through elaborative processing, such as linking new facts to existing knowledge.
心理学家通常描述三种记忆存储类型。感觉记忆将感官信息保持几分之一秒，刚好够我们决定该注意什么。短时记忆（STM）可以容纳约5–9个项目，保持约15–30秒，但通过复述可以延长。长时记忆（LTM）的容量几乎是无限的，信息可以存储几分钟到一辈子。信息通过精细加工，比如将新事实与已有知识联系起来，就能进入长时记忆。
Memory is also affected by factors like interference and context. Proactive interference happens when old knowledge makes it hard to learn new things, while retroactive interference is when new information pushes out old memories. Furthermore, we are more likely to recall information if we are in the same physical or emotional state as when we learned it — a phenomenon called context-dependent memory. These insights can help you plan more effective revision sessions.
记忆也受到干扰和语境等因素的影响。前摄干扰是指旧知识干扰新知识的学习，倒摄干扰则是新信息挤走旧记忆。此外，如果我们所处的身体或情绪状态与学习时相同，就更有可能回忆起信息——这种现象称为语境依存记忆。这些发现能帮助你规划更有效的复习方案。
4. Attachment: Bonds That Shape Us | 依恋：塑造我们的纽带
Attachment is the deep emotional bond that forms between an infant and its primary caregiver, usually the mother. This bond is not just about food; psychologists John Bowlby and Mary Ainsworth showed that attachment provides a secure base from which a child can explore the world. Bowlby argued that attachment behaviours, such as crying and clinging, are innate and promote survival by keeping the infant close to a protective adult.
依恋是婴儿与其主要照护者（通常是母亲）之间形成的深层情感联结。这种联结并不仅仅关乎食物；心理学家约翰·鲍尔比和玛丽·安斯沃思的研究表明，依恋为孩子提供了一个安全基地，让他们敢于探索世界。鲍尔比认为，哭闹和紧抓等依恋行为是与生俱来的，能通过让婴儿靠近提供保护的成人来促进生存。
Ainsworth’s famous ‘Strange Situation’ study identified three main attachment styles. Securely attached infants use their caregiver as a safe base, show moderate distress when separated and are easily comforted when reunited. Insecure-avoidant infants tend to ignore the caregiver and show little emotion when they leave or return. Insecure-resistant (or ambivalent) infants cling anxiously and are difficult to soothe even after reunion. A later category, disorganised attachment, describes infants who show confused and inconsistent responses.
安斯沃思著名的“陌生情境”研究识别出三种主要的依恋类型。安全型依恋的婴儿将照护者当作安全基地，分离时表现出适度的痛苦，重逢时容易被安慰。不安全-回避型婴儿倾向于忽略照护者，在照护者离开或返回时都表现出很少的情绪。不安全-抵抗型（或矛盾型）婴儿焦虑地紧抓不放，即使重聚后也难以被安抚。后来增加的一类，即混乱型依恋，描述的是表现出混乱且不一致反应的婴儿。
The quality of early attachment can influence later relationships. Children who experience warm, responsive caregiving tend to develop positive internal working models — mental frameworks for what to expect from others — and build healthier friendships and romantic bonds. However, it is important to note that early attachment is not destiny; later experiences, such as supportive teachers or partners, can reshape our expectations and social skills.
早期依恋的质量会影响后来的关系。经历过温暖、回应性照护的孩子往往会发展出积极的内部工作模型——即关于他人会如何对待自己的心理框架——并能建立更健康的友谊和亲密关系。不过，需要注意的是，早期依恋并非宿命；日后的经历，例如支持性的老师或伴侣，也能重塑我们的预期和社交技能。
5. Social Influence: Conformity and Obedience | 社会影响：从众与服从
Social influence is the process by which our thoughts, feelings and actions are affected by others. Two major forms you study in Year 7 are conformity and obedience. Conformity involves changing your behaviour or beliefs to fit in with a group, even without direct pressure. Obedience, on the other hand, means following a direct order from an authority figure.
社会影响是指我们的思想、情感和行动受到他人影响的过程。七年级需要学习两种主要形式：从众和服从。从众即为了融入群体而改变自己的行为或信念，即使没有直接的压力。而服从则意味着听从权威人物的直接命令。
A classic study on conformity was conducted by Solomon Asch. Participants were asked to judge the length of lines in a group where confederates deliberately gave wrong answers. About 75% of participants conformed at least once, even though the correct answer was obvious. This showed the power of normative social influence — the desire to be accepted — and informational social influence — the belief that the group knows better. Asch’s work reminds us that social pressure can be surprisingly strong.
关于从众的经典研究由所罗门·阿希进行。参与者被要求在一组人中判断线段长度，而组内的假成员故意给出错误答案。大约75%的参与者至少从众过一次，即使正确答案非常明显。这说明了规范性社会影响（渴望被接纳）和信息性社会影响（认为群体知道得更多）的力量。阿希的研究提醒我们，社会压力可以强大得令人惊讶。
Stanley Milgram’s obedience experiment is equally well-known. Participants were told to administer electric shocks to a ‘learner’ (an actor) every time a mistake was made. Under the instruction of an experimenter in a lab coat, 65% of participants continued to the highest shock level, even when the learner screamed (in reality, no real shocks were given). Milgram revealed that ordinary people are capable of harmful acts when ordered by an authority. Ethical concerns about deception and distress led to stricter guidelines, but the study remains a powerful lesson in human behaviour.
斯坦利·米尔格拉姆的服从实验同样著名。参与者被要求每当“学习者”（由演员扮演）犯错时就施加电击。在一名穿实验大褂的权威人物指令下，65%的参与者一直施加到最高电压，即便学习者发出了惨叫声（实际上并没有真正的电击）。米尔格拉姆揭示了，当接到权威人物命令时，普通人也能做出伤害性行为。尽管研究中的欺骗和痛苦引发了伦理担忧，并促成了更严格的准则，但它依然是关于人类行为的有力一课。
6. Cognitive Development: Piaget’s Theory | 认知发展：皮亚杰理论
Jean Piaget, a Swiss psychologist, proposed that children pass through four stages of cognitive development. He believed that children actively construct their understanding of the world through exploration and that their thinking is qualitatively different from adults’. His theory is central to Year 7 psychology because it explains how reasoning and problem-solving skills change with age.
瑞士心理学家让·皮亚杰提出，儿童会经历四个认知发展阶段。他认为儿童通过探索主动建构对世界的理解，并且儿童的思维方式与成人有质的区别。他的理论是七年级心理学的核心内容，因为它解释了推理和问题解决能力如何随年龄变化。
The first stage, the sensorimotor stage (from birth to about 2 years), is marked by learning through senses and actions. Infants develop object permanence — the understanding that objects continue to exist even when they are out of sight. The preoperational stage (about 2–7 years) sees the growth of language and imagination, but children are egocentric, meaning they struggle to see things from another’s viewpoint. In the concrete operational stage (about 7–11 years), logical thought about concrete events emerges, and children grasp the concept of conservation — that quantity stays the same even if appearance changes. Finally, in the formal operational stage (from about 12 years onwards), adolescents develop the ability to think abstractly, consider hypothetical situations and use deductive reasoning.
第一阶段是感知运动阶段（出生至约2岁），其特点是借助感官和动作来学习。婴儿逐渐形成客体永久性——即理解物体即使不在视野中也依然存在。前运算阶段（约2–7岁）中语言和想象力迅速成长，但儿童是自我中心的，难以从他人视角看问题。具体运算阶段（约7–11岁）出现了对具体事件的逻辑思维，儿童掌握了守恒概念——即数量即使外观改变也保持不变。最后，在形式运算阶段（约12岁起），青少年发展出抽象思维的能力，能够思考假设性情境并使用演绎推理。
Piaget’s work has influenced education greatly, encouraging ‘discovery learning’ and stage-appropriate tasks. However, critics argue that development is more continuous and that some children can reach stages earlier with support. Despite these challenges, Piaget’s stages remain a useful framework for understanding how the mind matures.
皮亚杰的工作对教育产生了深远影响，鼓励“发现学习”和与阶段匹配的任务。不过，批评者认为发展更为连续，且一些儿童在支持下可以更早达到各个阶段。尽管存在这些质疑，皮亚杰的阶段理论仍然是理解心智成熟过程的有用框架。
7. Introduction to Biopsychology | 生物心理学导论
Biopsychology, also called biological psychology, explores the links between our biological systems and our behaviour. In Year 7, you are introduced to the idea that everything psychological is simultaneously biological. This means your every thought, mood and memory is rooted in the activity of your brain, neurotransmitters and nervous system.
生物心理学，又称生物学心理学，探究我们生物系统与行为之间的联系。在七年级，你会接触到这样一个观念：一切心理现象同时也是生物现象。这意味着你的每一个想法、情绪和记忆都以大脑、神经递质和神经系统的活动为基础。
The nervous system is divided into the central nervous system (CNS), consisting of 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 of the nervous system. They communicate through electrical impulses and chemical messengers called neurotransmitters, such as serotonin (linked to mood) and dopamine (linked to pleasure and motivation). An imbalance in these chemicals can contribute to mental health difficulties.
神经系统分为中枢神经系统（CNS），由脑和脊髓组成，以及周围神经系统（PNS），它将中枢神经系统与身体其他部分连接起来。神经元是神经系统的基本构造单位。它们通过电冲动和称为神经递质的化学信使进行沟通，例如血清素（与情绪有关）和多巴胺（与愉悦和动机有关）。这些化学物质的不平衡可能导致心理健康问题。
Neuroplasticity is a key concept: the brain can change and reorganise itself throughout life in response to learning and experience. This is why practising a skill strengthens certain neural pathways. Understanding biopsychology helps you appreciate that even subtle changes in diet, sleep or stress can have real effects on how you feel and perform at school.
神经可塑性是一个关键概念：大脑能够根据学习和经验在一生中不断改变和重组自身。这就是为什么练习一项技能会强化特定的神经通路。理解生物心理学有助于你认识到，饮食、睡眠或压力方面的细微变化都能真实地影响你的感受和在校表现。
8. Early Understanding of Mental Health | 心理健康的初步认识
Mental health is about our emotional, psychological and social well-being. In Year 7 psychology, you learn that mental health is not simply the absence of illness — it is a continuum on which we all move back and forth depending on life events, biology and coping resources. Just like physical health, mental health requires attention and care.
心理健康关乎我们的情绪、心理和社交福祉。在七年级心理学中，你会学到心理健康不仅仅是“没有疾病”——它是一个连续体，我们都会根据生活事件、生理状况和应对资源在连续体上上下移动。就像身体健康一样，心理健康也需要关注和照顾。
Stress is a common experience that arises when the demands of a situation feel greater than our ability to cope. Short-term stress can be motivating, but chronic stress can lead to burnout, anxiety and physical illness. Researchers identify both external stressors, such as exams or conflicts with friends, and internal stressors, such as perfectionism. Healthy coping strategies include exercise, talking to someone you trust and learning relaxation techniques like deep breathing.
压力是一种常见体验，它发生在情境的要求似乎超出我们应对能力的时候。短期的压力可以具有激励作用，但长期压力可能导致倦怠、焦虑和身体疾病。研究者识别出外部压力源，如考试或与朋友的冲突，以及内部压力源，如完美主义。健康的应对策略包括锻炼、向信赖的人倾诉，以及学习深呼吸等放松技巧。
It is also vital to challenge stigma around mental health problems. Stigma is a mark of shame or disapproval that makes people afraid to seek help. Education and open conversations help reduce stigma and remind us that everyone has mental health — just as everyone has physical health. By learning these fundamentals early, you build a compassionate foundation for supporting yourself and others.
挑战围绕心理健康问题的污名同样至关重要。污名是一种带来羞耻或否定的标记，让人们不敢寻求帮助。教育和坦诚的对话有助于减少污名，并提醒我们每个人都有心理健康——就像每个人都有身体健康一样。尽早学习这些基础知识，你就能为自己和他人建立一份富有同情心的支持性根基。
