📚 Year 10 SQA Psychology Core Knowledge Review | 苏格兰 SQA 心理学核心知识点梳理
Psychology at Year 10 in the Scottish Qualifications Authority (SQA) curriculum introduces you to the scientific study of mind and behaviour. You will explore how psychologists design research, collect data, and explain why people think, feel and act the way they do. Understanding the core knowledge points will help you connect biological, cognitive, social and developmental perspectives, and prepare you for the National 5 assessment. This article walks you through the essential content you need to master, from research methods to key theories in social influence and memory.
苏格兰学历管理委员会（SQA）十年级心理学课程将带你走进关于心智与行为的科学研究。你将探索心理学家如何设计研究、收集数据，并解释人们为何会有特定的思维、情感和行为。掌握核心知识点有助于你将生物、认知、社会和发展等视角融会贯通，并为 National 5 评估做好准备。本文将带你梳理从研究方法到社会影响和记忆等关键理论的必学内容。
1. The Scientific Approach in Psychology | 心理学的科学方法
Psychology relies on the scientific method to gather evidence and test theories. This means researchers use systematic observation, measurement and experimentation to draw conclusions about behaviour. Unlike everyday thinking, the scientific approach minimises bias and allows findings to be replicated and verified by others. In SQA Psychology you will learn to identify aims, hypotheses, variables and how to design an investigation that is both ethical and valid.
心理学依赖科学方法来收集证据并验证理论。这意味着研究者通过系统观察、测量和实验来得出关于行为的结论。与日常思维不同，科学方法能最大程度减少偏差，让研究发现可以被他人重复和验证。在 SQA 心理学中，你将学会识别研究目的、假设、变量，以及如何设计一项既合乎伦理又有效的研究。
2. Research Methods: Experiments, Observations and Interviews | 研究方法：实验、观察与访谈
There are three main research methods you need to know: experiments, observations and interviews. An experiment involves manipulating an independent variable (IV) to see its effect on a dependent variable (DV) while controlling other factors. Observations can be structured or unstructured, participant or non‑participant, and are often used where experimentation is impractical. Interviews provide rich qualitative data and can be structured, semi‑structured or unstructured. Each method has strengths and limitations that affect reliability and validity.
你需要了解三种主要研究方法：实验、观察和访谈。实验涉及操纵自变量（IV）以观察其对因变量（DV）的影响，同时控制其他因素。观察可以是结构性或非结构性、参与性或非参与性的，常用于实验难以实施的场合。访谈能提供丰富的质性数据，可分为结构化、半结构化和非结构化。每种方法都有其优势和局限，会影响信度和效度。
3. Variables, Controls and Hypothesis Writing | 变量、控制与假设撰写
In any experiment, the independent variable is the factor you change, and the dependent variable is the factor you measure. Extraneous variables must be controlled so they do not become confounding variables that ruin your results. You should be able to write a clear experimental hypothesis (a testable prediction) and a null hypothesis (stating no effect or relationship). For example: ‘Participants who drink caffeine will complete a puzzle faster than those who drink water’ is a directional (one‑tailed) hypothesis.
在任何实验中，自变量是你改变的因素，因变量是你测量的结果。必须控制额外变量，以免它们成为混淆变量破坏结果。你需要能够写出清晰的实验假设（可验证的预测）和虚无假设（说明无效果或关系）。例如：“饮用咖啡因的参与者完成拼图的速度会比饮用水的参与者快”就是一个方向性（单尾）假设。
4. Sampling Techniques and Ethical Considerations | 抽样方法与伦理考量
Researchers must select participants from a target population. Common sampling methods include random sampling, opportunity sampling, stratified sampling and systematic sampling. Each method carries potential biases, such as volunteer bias or sampling bias. Ethical guidelines from the British Psychological Society (BPS) demand informed consent, right to withdraw, confidentiality, deception avoidance, debriefing and protection from harm. You must be able to apply these principles to study scenarios.
研究者必须从目标群体中选取参与者。常见的抽样方法包括随机抽样、便利抽样、分层抽样和系统抽样。每种方法都可能带有偏差，如志愿者偏差或抽样偏差。英国心理学会（BPS）的伦理准则要求知情同意、退出权、保密、避免欺骗、事后说明和免受伤害。你必须能在研究情境中应用这些原则。
5. Types of Data and Descriptive Statistics | 数据类型与描述统计
Data can be quantitative (numbers) or qualitative (words). Quantitative data is analysed using descriptive statistics such as the mean, median and mode. The mean is the average, the median is the middle value when ordered, and the mode is the most frequent value. The range (highest minus lowest) tells you about the spread of data. You should also be able to interpret bar charts, line graphs and scattergraphs, and understand what a normal distribution looks like.
数据可以是定量（数字）或定性（文字）。定量数据使用描述统计进行分析，如平均数、中位数和众数。平均数是所有数值之和除以个数，中位数是排序后的中间值，众数是出现频率最高的值。全距（最大值减最小值）反映数据的离散程度。你还需要能够解读条形图、折线图和散点图，并了解正态分布的形状。
6. Reliability, Validity and Generalisability | 信度、效度与推广性
Reliability means consistency: if you repeat the study you should get similar results. Validity means you are measuring what you intend to measure. Internal validity concerns whether the IV really caused the DV change; external validity concerns whether findings apply to other settings and people. A study can be reliable without being valid, but strong research needs both. Random allocation, standardised instructions and careful design improve reliability and validity.
信度指一致性：如果重复研究，应得到相似的结果。效度指你是否测量了想要测量的内容。内部效度关乎自变量是否真正导致了因变量的变化；外部效度则关乎研究结果能否推广到其他情境和人群。一项研究可以有信度却缺乏效度，但好的研究两者都需要。随机分配、标准化指导和精心设计能提高信度和效度。
7. The Multi‑Store Model of Memory | 记忆的多重存储模型
Atkinson and Shiffrin proposed that memory has three stores: sensory memory, short‑term memory (STM) and long‑term memory (LTM). Information enters sensory memory and, if attended to, moves to STM, which has a limited capacity of about 7±2 items and a duration of around 18–30 seconds. Through rehearsal, information can transfer to LTM, which has unlimited capacity and duration. This model explains primacy and recency effects in recall and highlights the importance of attention and rehearsal.
Atkinson 和 Shiffrin 提出记忆包含三个存储库：感觉记忆、短时记忆（STM）和长时记忆（LTM）。信息进入感觉记忆后，如果被注意，就会进入短时记忆，其容量大约为 7±2 个项目，持续时间约 18–30 秒。通过复述，信息可转入长时记忆，长时记忆的容量和持续时间无限。该模型解释了回忆中的首因效应和近因效应，并强调了注意和复述的重要性。
8. Factors Affecting Memory: Anxiety, Stereotypes and Leading Questions | 影响记忆的因素：焦虑、刻板印象与误导性问题
Eyewitness testimony research shows memory is reconstructive and easily distorted. Loftus and Palmer found that leading questions (e.g. ‘smashed’ vs ‘hit’) altered participants’ speed estimates and even false memories of broken glass. Anxiety can both enhance and impair memory; the Yerkes–Dodson law suggests moderate arousal is optimal. Stereotypes and schemas can also shape what we recall, often filling gaps with expectations rather than actual events.
目击者证词研究表明记忆是重构性的且容易失真。Loftus 和 Palmer 发现误导性问题（如“撞碎”与“碰撞”）会改变参与者对车速的估计，甚至产生玻璃碎裂的虚假记忆。焦虑既能增强也能损害记忆；耶克斯–多德森定律指出中等唤醒水平效果最佳。刻板印象和图式也会影响回忆，人们常以预期而非真实事件填补空白。
9. Attachment Theory and Styles | 依恋理论与类型
Attachment is the emotional bond between an infant and caregiver. Bowlby argued that attachment has survival value and that early bonds form an internal working model for future relationships. Ainsworth’s ‘Strange Situation’ identified three main attachment types: secure (happy to explore, distressed when left, easily comforted), insecure‑avoidant (indifferent, avoids contact) and insecure‑resistant (clingy, difficult to comfort). Cultural variations and caregiver sensitivity are key influences on attachment style.
依恋是婴儿与照料者之间的情感纽带。Bowlby 提出依恋具有生存价值，早期情感纽带会形成影响未来关系的内部工作模型。Ainsworth 的“陌生情境”实验识别出三种主要依恋类型：安全型（乐于探索，分离时苦恼，容易获得安慰）、不安全–回避型（冷漠，回避接触）和不安全–反抗型（粘人，难以安抚）。文化差异和照料者敏感性是依恋类型的关键影响因素。
10. Social Influence: Conformity, Obedience and Bystander Intervention | 社会影响：从众、服从与旁观者干预
Social influence examines how people’s behaviour is shaped by others. Conformity (Asch) is changing beliefs or behaviour to fit a group norm, often due to normative or informational social influence. Obedience (Milgram) shows that ordinary people can follow orders to the point of harming others when an authority figure is present. Bystander intervention research (Latané and Darley) found that the more witnesses there are, the less likely anyone will help (diffusion of responsibility). Understanding these forces helps explain both everyday compliance and extreme historical events.
社会影响研究人们的行为如何受他人塑造。从众（Asch）指因规范性或信息性社会影响而改变信念或行为以适应群体规范。服从（Milgram）表明普通人在权威人物在场时会听从指令甚至伤害他人。旁观者干预研究（Latané 和 Darley）发现，目击者越多，个体提供帮助的可能性越低（责任分散）。理解这些力量有助于解释日常顺从与极端历史事件。
11. Biological Influences on Behaviour: Brain and Nervous System Basics | 行为的生物影响：大脑与神经系统基础
Behaviour and mental processes are rooted in biological structures. You should know the central nervous system (brain and spinal cord) and peripheral nervous system. The brain is divided into areas like the frontal lobe (decision‑making, personality), temporal lobe (hearing, memory), occipital lobe (vision) and cerebellum (balance, coordination). Neurotransmitters such as serotonin and dopamine affect mood and motivation. Understanding the biological basis helps you evaluate mental health conditions and the effect of drugs on behaviour.
行为和心理过程根植于生物结构。你需要了解中枢神经系统（大脑和脊髓）和周围神经系统。大脑分为若干区域，如额叶（决策、人格）、颞叶（听觉、记忆）、枕叶（视觉）和小脑（平衡、协调）。神经递质如血清素和多巴胺会影响情绪和动机。理解生物基础有助于评估心理健康状况以及药物对行为的影响。
12. Applying Psychological Knowledge: Real‑World Links | 心理学知识的应用：现实连接
Psychology is not just theory; it applies to health, education, forensic and work settings. For instance, understanding cognitive biases improves decision‑making, memory research informs police interview techniques, and attachment theory guides childcare practices. In the SQA course, you will be expected to describe how psychological concepts and research findings relate to everyday life and society. Making these connections will deepen your understanding and prepare you for higher‑order exam questions.
心理学不仅仅是理论，它应用于健康、教育、司法和工作等领域。例如，了解认知偏差可改善决策，记忆研究可以指导警方审讯技巧，依恋理论则为儿童保育实践提供依据。在 SQA 课程中，你需要描述心理学概念和研究成果如何与日常生活及社会联系起来。建立这些联系将加深你的理解，并为高阶试题做好准备。
