📚 Year 12 SQA Psychology: Core Knowledge Review | Year 12 SQA 心理学：核心知识点梳理
This article provides a comprehensive review of the key knowledge areas covered in Year 12 SQA Higher Psychology. Understanding these core topics and the research behind them is essential for exam success and for developing a deeper appreciation of human behaviour.
本文全面梳理了 Year 12 SQA 高等心理学课程的核心知识点。掌握这些核心主题及其背后的经典研究，是考试成功的关键，也有助于更深入地理解人类行为。
1. Overview of SQA Higher Psychology | SQA 高等心理学课程概览
The SQA Higher Psychology course is structured around three units: Understanding the Individual, Investigating Behaviour, and The Individual in the Social Context. Each unit combines theoretical content with the evaluation of research studies, demanding both knowledge and critical thinking.
SQA 高等心理学课程由三个单元构成：理解个体、探究行为以及社会情境中的个体。每个单元都将理论内容与研究评价相结合，既要求考生掌握知识，也需要具备批判性思维能力。
Learners explore topics such as memory, sleep and dreams, conformity, obedience, and attachment. The course emphasises the application of research methods and ethical considerations, preparing students to analyse psychological evidence and construct balanced arguments.
学习者将探索记忆、睡眠与梦境、从众、服从以及依恋等主题。该课程强调研究方法和伦理考量的应用，培养学生分析心理学证据并构建辩证论点。
2. Research Methods and Ethics | 研究方法与伦理
A solid grasp of research methods underpins every topic in SQA Psychology. Students must be able to identify independent and dependent variables, distinguish between experimental and non-experimental designs, and evaluate the strengths and weaknesses of methods such as laboratory experiments, field experiments, questionnaires, and interviews.
扎实掌握研究方法是 SQA 心理学各专题的基础。学生必须能够识别自变量和因变量，区分实验与非实验设计，并评价实验室实验、现场实验、问卷调查和访谈等方法的优缺点。
Ethical principles are equally vital. Key guidelines include informed consent, the right to withdraw, protection from harm, confidentiality, and debriefing. The British Psychological Society (BPS) provides ethical standards that researchers must follow, and many classic studies raise important ethical debates.
伦理原则同样至关重要。核心准则包括知情同意、退出权、免受伤害、保密和事后解释。英国心理学会（BPS）提供了研究者必须遵循的伦理标准，许多经典研究都引发了重要的伦理争议。
For example, Milgram's obedience experiment (1963) famously raised concerns about deception and psychological distress. When revising, always link methodological strengths and weaknesses to specific studies to demonstrate analytical depth.
例如，米尔格拉姆的服从实验（1963）就因欺骗和心理压力而引发了著名的伦理担忧。复习时，务必将方法论的优缺点与具体研究联系起来，以展现分析深度。
3. Memory: The Multi-Store Model | 记忆：多存储模型
The multi-store model (Atkinson & Shiffrin, 1968) describes memory as consisting of three distinct stores: sensory memory, short-term memory (STM), and long-term memory (LTM). Information flows linearly, controlled by attention and rehearsal processes.
多存储模型（Atkinson & Shiffrin, 1968）将记忆描述为三个独立的存储系统：感觉记忆、短时记忆（STM）和长时记忆（LTM）。信息在注意和复述过程的控制下线性流动。
in iconic and echoic forms. STM has limited capacity (7±2 items) and duration (approx. 18– s model is supported by laboratory studies but oversimplifies the active nature of memory.
感觉记忆以图像和回声的形式短暂保存信息。STM 的容量有限（7±2 个项目），持续时间约 18–30 秒，而 LTM 被认为拥有无限容量，并能持续终生。该模型得到实验室研究的支持，但过度简化了记忆的主动加工特性。
4. Memory: The Working Memory Model | 记忆：工作记忆模型
Baddeley and Hitch (1974) proposed the working memory model as an alternative, focusing on the active processing of information. It comprises the central executive, the phonological loop, the visuospatial sketchpad, and the episodic buffer.
Baddeley 和 Hitch（1974）提出了工作记忆模型作为替代，强调信息的主动加工。该模型包含中央执行系统、语音回路、视空间画板以及情节缓冲器。
The central executive allocates attention; the phonological loop processes verbal and auditory information; the visuospatial sketchpad handles visual and spatial data; and the episodic buffer integrates information across domains. Studies using dual-task paradigms support the model, though the exact nature of the central executive remains vague.
中央执行系统负责分配注意；语音回路加工言语和听觉信息；视空间画板处理视觉与空间数据；情节缓冲器则整合跨域信息。双任务范式的研究支持了该模型，但中央执行系统的确切性质仍然模糊。
5. Sleep and Dreams: Biological Rhythms | 睡眠与梦境：生物节律
Sleep follows a predictable cycle of NREM (stages 1-4) and REM sleep. These cycles repeat roughly every 90 minutes. Stage 3 and 4 NREM sleep are deep, slow-wave sleep essential for restoration, while REM sleep is associated with vivid dreaming and brain activity resembling wakefulness.
睡眠遵循可预测的 NREM（1-4 阶段）和 REM 睡眠周期。这些周期大约每 90 分钟重复一次。第 3 和第 4 阶段 NREM 睡眠是深度慢波睡眠，对恢复至关重要，而 REM 睡眠与生动梦境以及类似清醒状态的大脑活动相关。
The SCN (suprachiasmatic nucleus) acts as the body’s master clock, regulating the sleep-wake cycle through melatonin secretion. Dement and Kleitman (1957) provided foundational research linking REM to dream recall, waking participants during different sleep stages to measure dream reports and eye movement patterns.
视交叉上核（SCN）作为身体的主时钟，通过褪黑激素的分泌调节睡眠-觉醒周期。Dement 和 Kleitman（1957）进行了奠基性研究，将 REM 与梦境回忆联系起来，他们在不同睡眠阶段唤醒参与者，以测量梦境报告和眼动模式。
6. Theories of Dreaming | 梦境理论
The activation-synthesis model (Hobson & McCarley, 1977) proposes that dreams result from the brain’s attempt to synthesise random neural signals originating in the pons during REM sleep. The cortex creates a narrative from this chaotic activation, which explains the bizarre quality of dreams.
激活-合成模型（Hobson & McCarley, 1977）提出，梦境源于大脑尝试在 REM 睡眠期间合成源自脑桥的随机神经信号。皮层从这种混乱的激活中建构叙事，这解释了梦境的离奇特质。
In contrast, the psychoanalytic theory (Freud, 1900) views dreams as the 'royal road to the unconscious', where latent content is disguised as manifest content through processes like symbolism and condensation. While the activation-synthesis theory has stronger neurophysiological support, Freudian ideas remain culturally influential but lack empirical falsifiability.
相比之下，精神分析理论（弗洛伊德，1900）将梦视为“通往无意识的捷径”，其中隐意通过象征和凝缩等机制伪装成显意。虽然激活-合成理论拥有更强的神经生理学支持，但弗洛伊德的思想在文化上仍有影响，却缺乏实证可证伪性。
7. Conformity: Asch and Social Influence | 从众：阿希与社会影响
Conformity refers to a change in behaviour or belief due to real or imagined group pressure. Asch (1951) conducted his classic line judgement task, finding that about 37% of critical trials yielded conforming responses even when the correct answer was obvious.
从众是指由于真实的或想象的群体压力而改变行为或信念。Asch（1951）进行了经典的线条判断任务，发现即使在正确答案显而易见的情况下，仍有约 37% 的关键试次产生了从众反应。
Factors affecting conformity include group size (increases up to a point), unanimity (a single dissenter dramatically reduces conformity), and task difficulty (ambiguity increases conformity). Asch's work highlights normative social influence – the desire to fit in – and informational influence when situations are ambiguous.
影响从众的因素包括群体规模（到达某临界点前增加）、一致性（只要有一个异议者，从众大幅减少）和任务难度（模糊性增加从众）。阿希的工作凸显了规范性社会影响——渴望融入——以及情境模糊时的信息性影响。
8. Obedience: Milgram and Authority | 服从：米尔格拉姆与权威
Obedience involves following a direct command from an authority figure. Milgram (1963) tested this in a controversial paradigm where 'teachers' were ordered to administer increasingly severe electric shocks to a 'learner'. A staggering 65% of participants delivered the maximum 450-volt shock.
服从涉及听从权威人物的直接命令。Milgram（1963）在一个有争议的范式中测试了这一点，在此范式中，“老师”被命令对“学习者”施加日益增强的电击。惊人的 65% 的参与者施加了最大的 450 伏电击。
Milgram identified situational factors such as proximity of the victim, legitimacy of the authority figure, and diffusion of responsibility. While the study revealed the power of the situation, it also sparked ongoing criticism regarding ethics, ecological validity, and demand characteristics.
米尔格拉姆识别出情境因素，如受害者的接近程度、权威人物的合法性以及责任分散。虽然该研究揭示了情境的强大力量，但也引发了关于伦理、生态效度和要求特征的持续批评。
9. Attachment Theory and the Strange Situation | 依恋理论与陌生情境
Attachment is a deep, enduring emotional bond between an infant and caregiver, crucial for survival and development. Bowlby (1969) argued that attachment evolved as an innate adaptive system, with babies displaying social releasers like crying and smiling to elicit caregiving.
依恋是婴儿与照料者之间深刻、持久的情感纽带，对生存和发展至关重要。Bowlby（1969）认为，依恋是作为一种先天适应系统进化而来的，婴儿通过哭泣和微笑等社会释放器来引发照料行为。
Ainsworth et al. (1978) developed the Strange Situation to classify attachment styles: secure, insecure-avoidant, and insecure-resistant. A highly standardised procedure involving separations and reunions revealed that sensitive responsiveness from the caregiver predicts secure attachment. Cultural variations exist, cautioning against universal application of the 'ideal' pattern.
Ainsworth 等人（1978）开发了陌生情境，用以分类依恋类型：安全型、不安全-回避型和不安全-抵抗型。这个高度标准化的程序包含分离和重聚，揭示了照料者的敏感回应能预测安全依恋。文化差异的存在提醒人们，不要将“理想”模式普遍化。
10. Non-Verbal Communication | 非言语交流
Non-verbal communication (NVC) conveys meaning through facial expressions, eye contact, body language, and personal space. It is often considered more powerful than verbal content in expressing emotion and regulating social interaction.
非言语交流（NVC）通过面部表情、眼神接触、身体语言和个人空间传达意义。在表达情绪和调节社会互动方面，它往往被认为比言语内容更有力。
Ekman's research on universal facial expressions identified six basic emotions — happiness, sadness, anger, fear, surprise, and disgust — that are recognised across cultures. However, display rules, which vary culturally, dictate when and how emotions are expressed. Eye contact can signal intimacy, threat, or confidence depending on context and duration.
艾克曼关于普遍面部表情的研究识别了六种基本情绪——快乐、悲伤、愤怒、恐惧、惊讶和厌恶——这些情绪在不同文化中均能被识别。然而，展示规则因文化而异，规定了何时以及如何表达情绪。眼神接触根据情境和持续时间，可以传递亲密、威胁或自信。
11. Individual Differences: Psychopathology | 个体差异：心理病理学
SQA Higher Psychology may examine individual differences through the lens of mental health and illness. Definitions of abnormality often rely on statistical infrequency, deviation from social norms, failure to function adequately, and deviation from ideal mental health (Jahoda, 1958).
SQA 高等心理学可能通过心理健康与疾病的视角考查个体差异。对异常的定义通常基于统计罕见性、偏离社会规范、功能失调以及偏离理想心理健康标准（Jahoda, 1958）。
Phobias, depression, and schizophrenia are frequently studied. Explanations range from biological (neurotransmitters, genetics) to psychological (cognitive biases, learning). Treatment approaches likewise differ, with evidence comparing the effectiveness of drugs, cognitive behavioural therapy (CBT), and systematic desensitisation.
恐惧症、抑郁症和精神分裂症是常见考查内容。解释范围从生物学（神经递质、遗传学）到心理学（认知偏差、学习）。治疗方法也各不相同，有证据比较了药物、认知行为疗法（CBT）和系统脱敏的效果。
12. Applying Knowledge: Exam Strategy | 知识应用：考试策略
To excel in SQA Psychology, move beyond description to evaluation. Use the PEEL structure (Point, Evidence, Evaluation, Link) to develop paragraphs. Always reference specific study details — researcher name, date, sample size, procedure — and link them back to the question.
要在 SQA 心理学中脱颖而出，就要从描述走向评价。运用 PEEL 结构（论点、证据、评价、联系）展开段落。始终引用具体的研究细节——研究者姓名、日期、样本量、程序——并联系回问题。
Practise writing balanced conclusions that weigh strengths against limitations. For research methods questions, focus on validity, reliability, generalisability, and ethics. Remember that command words like 'discuss', 'evaluate', and 'compare' demand high-order thinking.
练习写作均衡的结论，权衡优点与局限性。针对研究方法类问题，关注效度、信度、可推广性和伦理。记住“讨论”、“评价”和“比较”等指令词要求高阶思维。
