Year 10 SQA Psychology introduces learners to the scientific study of mind and behaviour. By exploring key approaches, research methods and classic studies, students build a foundation for understanding how psychologists investigate topics such as memory, attachment, conformity and mental health. This article brings together the essential core knowledge needed to feel confident in assessments, from ethical principles to the biological roots of behaviour.

SQA 十年级心理学课程引导学生科学地研究心理与行为。通过学习核心流派、研究方法和经典实验，学生将逐步理解心理学家如何探究记忆、依恋、从众和心理健康等主题。本文整合了评估所需的关键知识点，从伦理原则到行为的生物基础，帮助学习者建立清晰的知识框架。

1. The Scientific Approach in Psychology | 心理学中的科学方法

Psychology is a science because it uses empirical methods to test hypotheses. Researchers formulate a research question, design a study, collect data systematically and then analyse the results to draw conclusions. The process follows the hypothetico-deductive model, ensuring findings are objective and replicable. A key feature is the use of operational definitions to make abstract concepts (like ‘aggression’ or ‘memory’) measurable and testable.

心理学被视为一门科学，因为它采用实证方法检验假设。研究者提出研究问题、设计实验、系统收集数据，然后分析结果得出结论。整个过程遵循假设-演绎模型，确保研究结果客观且可重复。其关键特征在于使用操作性定义，使“攻击性”或“记忆力”等抽象概念变得可测量、可检验。

2. Research Methods: Experiments, Observations and Questionnaires | 研究方法：实验、观察与问卷

The three main research methods are experiments, observations and self-report techniques. Laboratory experiments offer high control and allow cause-and-effect conclusions, but may lack ecological validity. Field experiments take place in natural settings, increasing realism but reducing control. Naturalistic observation captures behaviour as it occurs spontaneously, while questionnaires and interviews gather self-report data on attitudes and experiences. Each method has strengths and weaknesses in terms of reliability, validity and ethical implications.

三大主要研究方法是实验法、观察法和自我报告法。实验室实验控制严格，能推断因果关系，但可能缺乏生态效度。现场实验在自然情境中进行，真实性更高但控制力降低。自然观察记录自发行为，而问卷和访谈则收集态度和经历等自我报告数据。每种方法在信度、效度和伦理影响方面各有优缺点。

3. Ethical Guidelines and the BPS Code | 伦理准则与英国心理学会规范

All psychological research must follow ethical principles: respect, competence, responsibility and integrity. The British Psychological Society (BPS) code requires informed consent, the right to withdraw, confidentiality and protection from harm. Deception should be avoided unless necessary, and participants must be debriefed afterwards. Special care is needed when working with vulnerable groups, including children under 16, where parental consent is mandatory.

所有心理研究都必须遵守伦理原则：尊重、胜任力、责任和诚信。英国心理学会（BPS）规范要求知情同意、退出权、保密和免受伤害。除非必要，应避免欺骗，且研究后必须对参与者进行事后说明。涉及弱势群体（包括16岁以下儿童）时需特别谨慎，必须获得家长同意。

4. The Biological Approach: Brain, Neurons and Neurotransmitters | 生物学取向：大脑、神经元与神经递质

The biological approach explains behaviour through brain structures, neural communication and hormones. Key brain areas include the prefrontal cortex for decision-making, the amygdala for fear responses and the hippocampus for memory formation. Neurons transmit signals via action potentials across synapses using neurotransmitters like serotonin (mood), dopamine (reward) and acetylcholine (muscle movement). Hormones such as adrenaline prepare the body for fight or flight. The approach uses scanning techniques like fMRI and PET to investigate brain activity.

生物学取向通过大脑结构、神经通讯和激素来解释行为。关键脑区包括负责决策的前额叶皮层、负责恐惧反应的杏仁核和负责记忆形成的海马体。神经元通过动作电位传递信号，在突触间释放神经递质，如血清素（情绪）、多巴胺（奖赏）和乙酰胆碱（肌肉运动）。肾上腺素等激素使身体进入战斗或逃跑状态。该取向使用fMRI和PET等扫描技术探究大脑活动。

5. The Cognitive Approach: Memory Models and Information Processing | 认知取向：记忆模型与信息加工

The cognitive approach compares the mind to a computer, focusing on internal mental processes like perception, attention, language and memory. The multi-store model (Atkinson and Shiffrin, 1968) proposes three stores: sensory register, short-term memory (STM) and long-term memory (LTM). Information moves through attention and rehearsal. STM has limited capacity (7 ± 2 items) and duration (about 18 seconds), while LTM is potentially unlimited. The working memory model (Baddeley and Hitch, 1974) adds the central executive, phonological loop and visuospatial sketchpad.

认知取向将心智比作计算机，关注知觉、注意、语言和记忆等内部心理过程。多贮存模型（Atkinson & Shiffrin, 1968）提出三种储存库：感觉登记器、短时记忆（STM）和长时记忆（LTM）。信息通过注意和复述进行传递。STM容量有限（7±2个组块）且保持时间短（约18秒），而LTM的容量和持续时间几乎无限。工作记忆模型（Baddeley & Hitch, 1974）增加了中央执行系统、语音环路和视空间画板。

6. Developmental Psychology: Attachment and Early Relationships | 发展心理学：依恋与早期关系

Attachment is a deep emotional bond between infant and caregiver that influences social and emotional development. Bowlby’s theory argues that attachment is an innate, adaptive behaviour that ensures survival. The ‘internal working model’ formed through early experiences guides future relationships. Ainsworth’s Strange Situation identified three attachment types: secure (type B), insecure-avoidant (type A) and insecure-resistant (type C). Later research added disorganised attachment (type D). Deprivation and privation can have long-term effects, as shown in studies of institutional care.

依恋是婴儿与照料者之间深刻的情感联结，影响社会与情感发展。鲍尔比的理论认为，依恋是一种先天的适应性行为，可确保生存。通过早期经验形成的“内部工作模型”会引导未来的人际关系。安斯沃斯的陌生情境实验识别出三种依恋类型：安全型（B型）、不安全-回避型（A型）和不安全-矛盾型（C型）。后续研究又增加了紊乱型（D型）。如孤儿院研究所示，情感剥夺与丧失可产生长期影响。

7. Social Psychology: Conformity, Obedience and Group Behaviour | 社会心理学：从众、服从与群体行为

Social influence studies how individuals’ thoughts and actions are shaped by others. Conformity (Asch, 1951) occurs when people adjust their behaviour or opinions to match group norms, even when the group is clearly wrong. Obedience (Milgram, 1963) involves following direct orders from an authority figure, raising profound ethical questions. Factors such as group size, unanimity and proximity affect the levels of conformity and obedience. Bystander intervention experiments show that the presence of others can inhibit helping behaviour (diffusion of responsibility).

社会影响研究个体的思想和行为如何受他人塑造。从众（Asch, 1951）指人们调整行为或意见以符合群体规范，即使群体明显错误。服从（Milgram, 1963）涉及听从权威人物的直接命令，引发了深刻的伦理争议。群体规模、一致性和接近度等因素会影响从众和服从的程度。旁观者干预实验表明，他人在场会抑制助人行为（责任扩散）。

8. Individual Differences: Personality and Mental Health | 个体差异：人格与心理健康

Individual differences psychology explores how people vary in terms of personality, intelligence and mental health. The Five-Factor Model (OCEAN) describes personality along openness, conscientiousness, extraversion, agreeableness and neuroticism. Intelligence is often measured using IQ tests, though cultural bias remains a concern. Understanding mental health includes defining abnormality (deviation from social norms, statistical infrequency, failure to function adequately and deviation from ideal mental health) and recognising symptoms of conditions like depression and phobias.

个体差异心理学探究人们在人格、智力和心理健康方面的差异。五因素模型（OCEAN）从开放性、尽责性、外向性、宜人性和神经质五个维度描述人格。智力通常通过智商测验测量，但文化偏见仍是一个问题。理解心理健康需要定义异常行为（偏离社会规范、统计稀有性、功能失效和偏离理想心理健康），并识别抑郁症和恐惧症等状况的症状。

9. Sleep and Dreams: Biological Rhythms and Theories | 睡眠与梦境：生物节律与理论

Sleep follows a circadian rhythm regulated by the suprachiasmatic nucleus (SCN) in the hypothalamus. The sleep cycle consists of NREM stages (1-3) and REM sleep, repeating roughly every 90 minutes. REM sleep is associated with vivid dreaming and memory consolidation. Theories of dreaming include the activation-synthesis model (Hobson & McCarley), which suggests dreams are the brain’s attempt to make sense of random neural signals, and Freud’s wish-fulfilment theory, which views dreams as a window into the unconscious. Sleep deprivation studies reveal negative effects on cognition, mood and physical health.

睡眠遵循视交叉上核（SCN）调控的昼夜节律。睡眠周期由非快速眼动睡眠（1-3阶段）和快速眼动睡眠（REM）组成，约每90分钟循环一次。REM睡眠与生动梦境和记忆巩固有关。梦境理论包括激活-合成模型（Hobson & McCarley），认为梦是大脑对随机神经信号的解读，以及弗洛伊德的愿望实现理论，视梦为潜意识的窗口。睡眠剥夺研究揭示了其对认知、情绪和身体健康的不利影响。

10. Research Design and Data Analysis | 研究设计与数据分析

Good research design controls for extraneous variables to ensure internal validity. Independent measures, repeated measures and matched pairs are common experimental designs. Non-experimental methods like correlations show relationships between variables but cannot prove causation. Data can be quantitative (numbers) or qualitative (words). Descriptive statistics such as mean, median, mode and range summarise data, while bar charts and scattergrams display patterns. Ethical reporting includes peer review, acknowledging limitations and avoiding overgeneralisation.

良好的研究设计能控制额外变量，确保内部效度。独立组设计、重复测量设计和匹配对设计是常见的实验设计。相关法等非实验方法能显示变量间的关系，但无法证明因果关系。数据可分为定量（数字）和定性（文字）。平均数、中位数、众数和全距等描述性统计可概括数据，柱状图和散点图则展示模式。合乎伦理的报告包括同行评审、承认局限性和避免过度概括。
