欢迎来到八年级 SQA 心理学复习指南。本文汇集了你将在课程中遇到的核心概念。心理学是一门迷人的学科，它帮助我们理解人们为什么会有这样的思维、感受和行为。掌握这些关键思想，你将为未来的学习打下坚实的基础，并培养适用于日常生活的批判性思维能力。
1. What is Psychology? | 心理学是什么？
Psychology is defined as the scientific study of the mind and behaviour. It goes beyond simple speculation and relies on empirical evidence gathered through systematic methods such as experiments and observations. Psychologists aim to describe what people do, explain the underlying causes, predict future behaviour, and sometimes modify problematic behaviour.
心理学被定义为对心理和行为的科学研究。它超越了简单的猜测，依赖于通过实验和观察等系统方法收集的经验证据。心理学家旨在描述人们的行为，解释其背后的原因，预测未来的行为，有时还会调整问题行为。
For example, a psychologist might investigate why some students experience test anxiety and develop strategies to help them cope. This process shows how psychological research directly relates to improving people's lives.
例如，心理学家可能会研究为什么一些学生有考试焦虑，并制定应对策略来帮助他们。这个过程展示了心理学研究如何直接改善人们的生活。
2. Key Research Methods | 主要研究方法
Experiments are the most controlled research method. A researcher manipulates an independent variable (IV) to see its effect on a dependent variable (DV), while holding other factors constant. This allows cause-and-effect conclusions. For instance, testing whether background music (IV) affects memory test scores (DV). An experiment uses random allocation of participants to conditions to reduce bias.
实验是最具控制性的研究方法。研究者操纵自变量 (IV)，观察其对因变量 (DV) 的影响，同时保持其他因素恒定。这可以得出因果结论。例如，测试背景音乐（自变量）是否影响记忆测试成绩（因变量）。实验将参与者随机分配到不同条件中，以减少偏差。
Naturalistic observation involves watching behaviour in a real-world setting without interference. This provides high ecological validity because the behaviour is spontaneous. However, the observer cannot control variables, making it hard to establish causes. An example would be observing children's sharing behaviour in a playground.
自然观察法包括在真实环境中观察行为而不加干预。这种方法具有较高的生态效度，因为行为是自发的。然而，观察者无法控制变量，因此难以确定因果关系。一个例子是在操场上观察儿童的分享行为。
Self-report techniques like questionnaires and interviews gather data directly from people about their thoughts, feelings, and behaviours. They can reach many participants quickly, but responses may be biased by social desirability – people might answer in a way they think is acceptable rather than being truthful.
自我报告技术如问卷和访谈，直接从人们那里收集关于其思想、感受和行为的数据。它们能快速触及大量参与者，但回答可能因社会称许性而产生偏差——人们可能以他们认为可接受的方式回答，而不是真实回答。
A case study is an in-depth investigation of a single individual, group, or event. This method generates rich, detailed data and can highlight unusual conditions, like rare brain damage. The main limitation is that findings cannot be easily generalised to the wider population.
案例研究是对单一个体、群体或事件进行深入调查。这种方法可以产生丰富、详细的数据，并能突显异常情况，如罕见的脑损伤。主要局限是研究结果无法轻易推广到更广泛的人群。
3. The Brain and Behaviour | 大脑与行为
The human brain is divided into four main lobes: frontal (thinking, planning, personality), temporal (auditory processing, memory), occipital (vision), and parietal (sensory integration). Each lobe has specific functions, but they work together. Damage to the frontal lobe, for example, can lead to changes in personality and decision-making.
人类大脑分为四个主要脑叶：额叶（思维、计划、人格）、颞叶（听觉处理、记忆）、枕叶（视觉）和顶叶（感觉整合）。每个脑叶都有特定的功能，但它们协同工作。例如，额叶损伤可能导致人格和决策能力的变化。
Neurons are the basic building blocks of the nervous system. They communicate through electrical and chemical signals. A typical neuron has a cell body, dendrites (receivers), and an axon (sender). Neurotransmitters, such as dopamine and serotonin, are released at synapses to transmit messages between neurons. Imbalances in these chemicals are linked to mood and behaviour disorders.
神经元是神经系统的基本构建单元。它们通过电信号和化学信号进行通信。一个典型的神经元包括细胞体、树突（接收端）和轴突（发送端）。神经递质，如多巴胺和血清素，在突触间释放，以在神经元之间传递信息。这些化学物质的失衡与情绪和行为障碍有关。
4. Memory Processes | 记忆过程
Memory is often described as a three-stage process: encoding (converting sensory input into a form that can be stored), storage (maintaining information over time), and retrieval (accessing stored information). This model helps explain why we forget – perhaps encoding was shallow, storage decayed, or retrieval cues were inadequate.
记忆常被描述为一个三阶段过程：编码（将感觉输入转换为可存储的形式）、存储（随时间保持信息）和提取（获取存储的信息）。这个模型有助于解释我们为什么会遗忘——可能是编码较浅、存储衰退，或者提取线索不足。
Sensory memory holds an exact copy of sensory input for a fraction of a second. Iconic memory (visual) lasts about 0.5 seconds, while echoic memory (auditory) lasts 2–3 seconds. This brief storage allows us to process the continuous stream of information and decide what to attend to.
感觉记忆在不到一秒的时间内保持感觉输入的精确副本。图像记忆（视觉）持续约0.5秒，而回声记忆（听觉）持续2-3秒。这种短暂的存储使我们能够处理连续的信息流，并决定关注什么。
Short-term memory (STM) can hold about 5–9 items for around 20–30 seconds without rehearsal. Rehearsal can transfer information into long-term memory (LTM), which has potentially unlimited capacity and duration. LTM stores facts (semantic), personal events (episodic), and skills (procedural). Forgetting from STM often occurs through displacement, while forgetting from LTM may be due to interference or retrieval failure.
短时记忆(STM)在没有复述的情况下，可以保持大约5-9个项目，持续约20-30秒。复述可以将信息转移到长时记忆(LTM)，后者拥有几乎无限的容量和持续时间。长时记忆存储事实（语义记忆）、个人事件（情景记忆）和技能（程序性记忆）。短时记忆的遗忘通常由替代引起，而长时记忆的遗忘可能源于干扰或提取失败。
5. Learning Theories | 学习理论
Discovered by Ivan Pavlov, classical conditioning is learning through association. A neutral stimulus (e.g., a bell) is repeatedly paired with an unconditioned stimulus (food) that triggers an unconditioned response (salivation). Eventually, the neutral stimulus alone becomes a conditioned stimulus that elicits the conditioned response. This theory explains many emotional reactions, such as phobias.
由伊万·巴甫洛夫发现，经典条件反射是通过联想进行学习。一个中性刺激（如铃声）与引发无条件反应（唾液分泌）的无条件刺激（食物）反复配对。最终，中性刺激单独就成为能引发条件反应的条件刺激。这一理论解释了许多情绪反应，如恐惧症。
B.F. Skinner demonstrated operant conditioning, where behaviour is shaped by consequences. Positive reinforcement (adding a pleasant stimulus, like praise) increases behaviour; negative reinforcement (removing an unpleasant stimulus, like homework) also increases behaviour. Punishment, on the other hand, decreases behaviour. This principle is widely used in classrooms and parenting.
B.F. 斯金纳展示了操作性条件反射，即行为由后果塑造。正强化（增加愉快的刺激，如表扬）会增加行为；负强化（移除不愉快的刺激，如作业）也会增加行为。而惩罚则会减少行为。这一原则广泛应用于课堂和育儿中。
Albert Bandura proposed that people learn by observing others (models). His Bobo doll experiment showed that children imitate aggressive behaviour they see. For observational learning to occur, attention, retention, reproduction, and motivation are necessary. This highlights the importance of role models in social development.
阿尔伯特·班杜拉提出，人们通过观察他人（榜样）进行学习。他的波波玩偶实验表明，儿童会模仿他们看到的攻击性行为。观察学习发生需要具备注意、保持、再现和动机。这突显了榜样在社会发展中的重要性。
6. Social Influence: Conformity and Obedience | 社会影响：从众与服从
Conformity is a change in behaviour or belief to fit in with a group. Solomon Asch's line judgement study (1951) revealed that participants often gave an obviously wrong answer to match the group, demonstrating normative social influence – the desire to be liked and accepted. Size of the group and unanimity affect conformity levels.
从众是为了融入群体而改变行为或信念。所罗门·阿希的线段判断实验（1951年）揭示，参与者经常给出明显错误的答案以与群体保持一致，这体现了规范社会影响——渴望被喜爱和接纳。群体规模和一致性会影响从众的程度。
Obedience involves following orders from an authority figure. Stanley Milgram's (1963) electric shock experiment showed that ordinary people were willing to administer what they thought were dangerous shocks to another person when instructed by an authoritative experimenter. This study raised profound ethical questions and showed the power of situational factors like proximity and perceived legitimacy.
服从涉及遵循权威人物的命令。斯坦利·米尔格拉姆（1963年）的电击实验表明，当有权威的实验者指示时，普通人愿意对另一个人施加他们认为危险的点击。这项研究提出了深刻的伦理问题，并显示了情境因素（如接近性和感知的合法性）的强大力量。
7. Attachment in Early Development | 早期发展中的依恋
Attachment is a deep emotional bond that develops between an infant and their primary caregiver, usually the mother. John Bowlby argued that attachment is an innate biological drive for survival and has a critical period in early childhood. Secure attachment provides a safe base for exploration and healthy social-emotional development.
依恋是婴儿与其主要照顾者（通常是母亲）之间发展出的深厚情感纽带。约翰·鲍尔比认为，依恋是一种天生的生存驱动力，并且在幼儿期有关键期。安全型依恋为探索和健康的社会情感发展提供了一个安全基地。
Mary Ainsworth's 'Strange Situation' procedure identified three main attachment styles: secure, insecure-avoidant, and insecure-resistant/ambivalent. Securely attached children show distress when the caregiver leaves but are easily comforted upon return. Avoidant children seem indifferent, while resistant children are clingy but not comforted. These patterns are influenced by caregiving sensitivity and can affect later relationships.
玛丽·安斯沃思的"陌生情境"实验确定了三种主要的依恋类型：安全型、不安全-回避型和不安全-反抗/矛盾型。安全型依恋的儿童在照顾者离开时表现出痛苦，但回来时容易得到安慰。回避型儿童显得漠不关心，而反抗型儿童既黏人又难以安抚。这些模式受照顾者敏感性的影响，并可能影响后来的关系。
8. Perception and Illusions | 知觉与错觉
Perception is the brain's interpretation of sensory information. Bottom-up processing builds perception from raw sensory data, while top-down processing uses prior knowledge, expectations, and context to interpret sensations. For example, reading a handwritten word uses top-down processing when we recognise poorly formed letters.
知觉是大脑对感觉信息的解释。自下而上的加工从原始感觉数据构建知觉，而自上而下的加工则利用先前的知识、期望和背景
