1. What is Psychology? | 什么是心理学？
Psychology is defined as the scientific study of mental processes and behaviour. It seeks to describe, explain, predict, and sometimes change how individuals think and act.
心理学被定义为对心理过程与行为的科学研究。它试图描述、解释、预测，有时还改变个体的思维和行为方式。
Unlike everyday intuition, psychology relies on empirical evidence collected through systematic observation, experiments, and careful measurement. It is not just about therapy or mental illness—it spans everything from memory and learning to social relationships and brain function.
与日常直觉不同，心理学依赖通过系统观察、实验和精密测量收集的经验证据。它不仅仅涉及治疗或心理疾病，而是涵盖从记忆、学习到社会关系和大脑功能的一切。
The word 'psychology' comes from the Greek words 'psyche' (soul or mind) and 'logos' (study), highlighting its roots as the study of the mind.
“心理学”一词源自希腊语“psyche”（灵魂或心灵）和“logos”（研究），凸显了它作为心灵研究的本源。
2. The Main Approaches in Psychology | 心理学的主要流派
There are several key approaches in psychology, each offering a different lens through which to understand human behaviour. The main approaches taught at Year 8 level include the biological, cognitive, behavioural, psychodynamic, and humanistic perspectives.
心理学中有多个主要流派，每一个都提供了理解人类行为的不同视角。Year 8 阶段讲授的主要流派包括生物学、认知、行为主义、心理动力学和人本主义视角。
The biological approach emphasises the role of the brain, nervous system, hormones, and genetics in shaping behaviour. For instance, differences in neurotransmitter levels can influence mood and aggression.
生物学流派强调大脑、神经系统、激素和遗传在行为塑造中的作用。例如，神经递质水平的差异可以影响情绪和攻击性。
The cognitive approach focuses on internal mental processes such as thinking, memory, perception, and problem-solving. It compares the mind to a computer that receives, processes, stores, and retrieves information.
认知流派关注内部心理过程，如思维、记忆、知觉和问题解决。它将心灵比作接收、加工、存储和检索信息的计算机。
The behavioural approach concentrates on observable behaviour and how it is learned through interaction with the environment, especially through classical and operant conditioning. Important figures include Ivan Pavlov and B.F. Skinner.
行为主义流派专注于可观察的行为以及如何通过与环境的互动——尤其是经典条件反射和操作条件反射——习得行为。重要人物包括伊凡·巴甫洛夫和 B.F. 斯金纳。
The psychodynamic approach, founded by Sigmund Freud, stresses the influence of the unconscious mind and early childhood experiences on conscious thoughts and actions.
由西格蒙德·弗洛伊德创立的心理动力学流派强调无意识心理和早期童年经历对意识思维和行动的影响。
The humanistic approach highlights personal growth, free will, and the idea that everyone strives towards self-actualisation. Key theorists are Carl Rogers and Abraham Maslow.
人本主义流派强调个人成长、自由意志，以及每个人都努力朝着自我实现前进的理念。核心理论家是卡尔·罗杰斯和亚伯拉罕·马斯洛。
3. Research Methods: Experiments | 研究方法：实验法
Experiments are the most powerful method for establishing cause-and-effect relationships. In an experiment, the researcher manipulates an independent variable (IV) and measures the effect on a dependent variable (DV), while controlling other factors.
实验是确立因果关系最有力的方法。在实验中，研究者操纵自变量 (IV)，测量它对因变量 (DV) 的影响，同时控制其他因素。
A laboratory experiment takes place in a controlled, artificial environment, allowing precise control of extraneous variables. However, it can sometimes lack ecological validity because the setting does not reflect real life.
实验室实验在受控的人造环境中进行，能够精确控制额外变量。然而，它有时可能缺乏生态效度，因为实验环境不能反映真实生活。
A field experiment is conducted in a natural setting, so participants often behave more naturally. The researcher still manipulates the IV but has less control over confounding variables.
现场实验在自然环境中进行，因此参与者表现得更自然。研究者仍然操纵自变量，但对混淆变量的控制较弱。
An essential concept is the hypothesis: a clear, testable statement predicting the relationship between the IV and DV. For example: 'Students who sleep for 8 hours will score higher on a memory test than those who sleep for 4 hours.'
一个核心概念是假设：一个清晰、可检验的陈述，预测自变量与因变量之间的关系。例如：“睡眠 8 小时的学生在记忆测试中的得分将高于睡眠 4 小时的学生。”
4. Research Methods: Non-experimental Methods | 研究方法：非实验法
Not all psychological research uses experiments. Observations, questionnaires, interviews, and case studies are also widely used.
并非所有心理学研究都使用实验。观察法、问卷法、访谈法和案例研究也被广泛使用。
Observational studies involve watching and recording behaviour in a natural or controlled setting. They can be overt (participants know they are observed) or covert (they do not know), structured or unstructured.
观察性研究涉及在自然或受控环境中观察和记录行为。它们可以是公开的（参与者知道自己被观察）或隐蔽的（他们不知道），也可以是有结构的或无结构的。
Questionnaires and interviews collect self-report data. They can provide rich information but are prone to social desirability bias, where respondents give answers they feel are more acceptable.
问卷和访谈收集自我报告数据。它们能提供丰富的信息，但容易出现社会赞许性偏差，即受访者给出他们认为更容易接受的答案。
Case studies involve an in-depth investigation of a single individual, group, or event. They produce detailed qualitative data but lack generalisability because of the small sample size. A famous example is the study of Phineas Gage, whose personality changed after a severe brain injury.
案例研究涉及对单个个体、群体或事件进行深入调查。它们产生详细的定性数据，但由于样本量小，缺乏可推广性。一个著名例子是对菲尼亚斯·盖奇的研究，他在遭受严重脑损伤后性格发生了变化。
Correlational research measures the strength and direction of a relationship between two variables without manipulation. A correlation coefficient (r) ranges from -1 to +1.
r = Σ(X − x̄)(Y − ȳ) / √[Σ(X − x̄)² Σ(Y − ȳ)²]
相关研究在无操纵的情况下测量两个变量之间关系的强度和方向。相关系数 (r) 的取值范围从 -1 到 +1。
5. Ethical Considerations | 伦理考量
Ethics are moral principles that guide researchers to ensure the well-being and dignity of participants. The British Psychological Society (BPS) sets strict ethical guidelines that all UK psychologists must follow.
伦理是指导研究者确保参与者福祉和尊严的道德原则。英国心理学会 (BPS) 制定了所有英国心理学家必须遵守的严格伦理指南。
The main ethical issues include informed consent (participants must know the nature of the study and agree to take part), the right to withdraw at any time, confidentiality, protection from psychological and physical harm, and debriefing after the study.
主要的伦理问题包括知情同意（参与者必须了解研究的性质并同意参与）、随时退出的权利、保密原则、免受心理和身体伤害的保护，以及研究结束后的解释说明。
Sometimes deception is necessary, but it should be minimised and justified. If used, researchers must debrief participants fully, revealing the true nature of the study and allowing questions.
有时欺骗是必要的，但它应该被最小化且具有正当理由。如果使用了欺骗，研究者必须对参与者进行全面解释，揭示研究的真实性质并允许提问。
A lack of ethical awareness can lead to long-lasting psychological damage, as seen in some classic studies that would not be approved today. This is why ethics committees review all proposals before research can begin.
缺乏伦理意识可能导致持久的心理伤害，这在一些不会得到今天批准的经典研究中可以看到。这就是为什么伦理委员会必须在研究开始前审查所有方案。
6. Memory: The Multi-Store Model | 记忆：多存储模型
Atkinson and Shiffrin (1968) proposed the multi-store model of memory, which describes three separate stores: sensory memory, short-term memory (STM), and long-term memory (LTM). Information flows sequentially through these stores.
阿特金森和希夫林 (1968) 提出了多存储记忆模型，描述了三个独立的存储系统：感觉记忆、短时记忆 (STM) 和长时记忆 (LTM)。信息按顺序流经这些存储系统。
Sensory memory holds information from the senses for a very brief period (a few seconds). If we pay attention to this information, it passes into STM. Otherwise, it decays rapidly.
感觉记忆在极短的时间内（几秒钟）保存来自感官的信息。如果我们注意这些信息，它就会进入短时记忆；否则迅速消退。
STM has a limited capacity of about 7 ± 2 items (Miller, 1956) and a duration of around 18– ves repeating information to keep it in STM, and if rehearsed enough, it transfers to LTM.
短时记忆容量有限，约为 7±2 个项目 (Miller, 1956)，持续时间在无复述的情况下大约为 18 至 30 秒。维持性复述通过重复信息来将其保留在短时记忆中，如果复述足够多，就会转入长时记忆。
LTM has a potentially unlimited capacity and can store information for a lifetime. It is coded mainly by meaning (semantically), which explains why we remember the gist of a story rather than exact words.
长时记忆的容量可能无限，可以终身存储信息。它主要按意义进行编码（语义编码），这解释了为什么我们记住的是故事的要点，而不是确切的词语。
A strength of the model is its simplicity and the research support from amnesia patients. A weakness is that it oversimplifies memory, treating STM and LTM as single units while evidence suggests there are different types of LTM (episodic, semantic, procedural).
该模型的一个优势是它的简单性以及来自失忆症患者的研究支持。一个局限性是它过度简化了记忆，将短时和长时记忆视为单一单元，而有证据表明长时记忆存在不同类型（情景、语义、程序性）。
7. Social Influence: Conformity | 社会影响：从众
Conformity is the tendency to change one’s beliefs or behaviour to fit in with a group. It can occur because of normative social influence (wanting to be liked and accepted) or informational social influence (believing the group is right).
从众是指改变自己的信念或行为以融入群体的倾向。它可能源于规范社会影响（希望被喜欢和接纳）或信息性社会影响（相信群体是正确的）。
Solomon Asch's (1951) line judgment experiment is a classic demonstration. Participants had to say which of three lines matched a standard line; confederates purposely gave wrong answers on critical trials. About 75% of real participants conformed at least once.
所罗门·阿希 (1951) 的线段判断实验是一个经典例证。参与者必须说出三条线段中哪一条与标准线匹配；同谋在关键试验中故意给出错误答案。大约 75% 的真实参与者至少从众了一次。
Factors affecting conformity include group size (conformity increases up to about 4–5 confederates), unanimity (if one confederate gives the correct answer, conformity drops sharply), and task difficulty (people conform more when tasks are ambiguous).
影响从众的因素包括群体规模（从众随人数增加而上升，直到大约 4 到 5 名同谋后趋于平稳）、一致性（如果有一名同谋给出正确答案，从众率急剧下降），以及任务难度（当任务模糊不清时，人们更容易从众）。
Conformity is not always negative; it can serve important social functions, such as maintaining order and cohesion. However, blind conformity can lead to poor decision-making, as found in groupthink phenomena.
从众并不总是负面的；它可以承担重要的社会功能，如维护秩序和凝聚力。然而，盲目从众可能导致糟糕的决策，正如群体思维现象中所发现的。
8. Social Influence: Obedience to Authority | 社会影响：服从权威
Obedience involves following a direct order from an authority figure, even when it goes against one’s personal values. Stanley Milgram’s (1963) study at Yale University dramatically demonstrated how far people would go in obeying harmful commands.
服从涉及遵循权威人物发出的直接命令，即使这违背个人价值观。斯坦利·米尔格拉姆 (1963) 在耶鲁大学进行的研究戏剧性地展示了人们在服从有害指令方面会有多远。
In Milgram's experiment, a participant (teacher) was instructed to administer increasingly strong electric shocks to a learner (confederate) for each mistake. Despite the learner's screams and eventual silence, 65% of participants continued to the maximum 450-volt shock level.
在米尔格拉姆的实验中，一名参与者（教师）被指示在“学习者”（同谋）每次犯错时施加越来越强的电击。尽管学习者发出尖叫并最终沉默，仍有 65% 的参与者继续施加到了最高 450 伏的电击水平。
Key factors that influence obedience include the proximity of the authority figure (higher when the authority is in the room), the legitimacy of the setting (prestigious university vs. run-down office), and the proximity of the victim. This research raised crucial ethical debates but remains highly relevant.
影响服从的关键因素包括权威人物的接近程度（当权威在房间内时服从率更高）、环境的正统性（著名大学 vs. 破旧办公室），以及受害者的接近程度。这项研究引发了重要的伦理争论，但至今仍高度相关。
Real-life applications include understanding atrocities during wartime and the importance of whistleblowing systems. Obedience can be reduced by empowering individuals to question authority and by making the consequences of blind obedience explicit.
现实生活中的应用包括理解战争期间的暴行和举报制度的重要性。通过赋予个体质疑权威的能力，并明确盲目服从的后果，可以降低服从程度。
9. Attachment Theory | 依恋理论
Attachment is a strong emotional bond that forms between an infant and a primary caregiver. John Bowlby (1969) argued that this bond has an evolutionary basis, because staying close to the caregiver increases the infant's chance of survival.
依恋是婴儿与其主要照顾者之间形成的一种强烈情感纽带。约翰·鲍尔比 (1969) 认为，这种纽带具有进化基础，因为与照顾者保持亲近能够增加婴儿的生存几率。
Mary Ainsworth (1978) developed the 'Strange Situation' procedure to assess attachment styles. She identified three main types: secure attachment (infant explores, shows mild distress on separation, and is happy on reunion), insecure-avoidant (ignores caregiver, no distress), and insecure-resistant (great distress, mixed reactions on reunion).
玛丽·安斯沃思 (1978) 开发了“陌生情境”程序来评估依恋类型。她识别出三种主要类型：安全型依恋（婴儿探索环境，分离时表现出轻度痛苦，重聚时高兴）、不安全-回避型（忽略照顾者，无痛苦）和不安全-矛盾型（极度痛苦，重聚时反应矛盾）。
Secure attachment is associated with better social and emotional outcomes later in life, while insecure patterns are linked to relationship difficulties. Parenting sensitivity—prompt and appropriate responding to an infant’s cues—is a strong predictor of secure attachment.
安全型依恋与日后更好的社会及情感发展结果相关，而不安全型模式则与人际关系困难有关。养育敏感性——对婴儿信号做出及时恰当的反应——是安全型依恋的有力预测因素。
The theory has been criticised for being culturally biased, as Western ideals of independence and exploration may not be valued equally in all societies. Nonetheless, attachment research has profoundly influenced childcare practices worldwide.
该理论因存在文化偏见而受到批评，因为西方关于独立和探索的理想并不在所有社会中得到同等重视。尽管如此，依恋研究对全球育儿实践产生了深远影响。
10. Piaget's Theory of Cognitive Development | 皮亚杰认知发展理论
Jean Piaget proposed that children go through four distinct stages of cognitive development, each marked by qualitative differences in thinking. These stages are sensorimotor, preoperational, concrete operational, and formal operational.
让·皮亚杰提出，儿童经历四个独特的认知发展阶段，每个阶段在思维方式上都有质的差异。这些阶段分别是感知运动阶段、前运算阶段、具体运算阶段和形式运算阶段。
In the sensorimotor stage (0–2 years), infants learn through senses and motor actions. A major milestone is object permanence—the understanding that objects continue to exist even when out of sight.
在感知运动阶段（0-2 岁），婴儿通过感官和运动动作学习。一个重要的里程碑是客体永久性——理解物体即使看不见也依然存在。
During the preoperational stage (2–7 years), children develop language and symbolic thinking but are egocentric (cannot see situations from others’ perspectives) and lack conservation—the knowledge that quantity remains the same despite changes in appearance.
在前运算阶段（2-7 岁），儿童发展出语言和象征性思维，但以自我为中心（无法从他人视角看问题），并缺乏守恒概念——即知道数量在外观改变后仍保持不变。
In the concrete operational stage (7–11 years), logical thinking emerges about concrete events. Children master conservation, classification, and seriation, but struggle with abstract or hypothetical reasoning.
在具体运算阶段（7-11 岁），逻辑思维开始出现，但仅限于具体事件。儿童掌握了守恒、分类和排序，但对抽象或假设性推理仍有困难。
At the formal operational stage (11+ years), adolescents develop the capacity for abstract, scientific reasoning, and can think about hypothetical possibilities, future events, and moral dilemmas.
在形式运算阶段（11 岁以上），青少年发展出抽象科学推理的能力，能够思考假设性可能、未来事件和道德困境。
While Piaget's stages have been supported by many cross-cultural studies, critics argue that he underestimated younger children's abilities and that cognitive development may be more continuous than stage-like.
尽管皮亚杰的阶段得到许多跨文化研究的支持，但批评者认为他低估了年幼儿童的能力，并且认知发展可能比阶段状更连续。
11. Personality: Eysenck's Theory | 人格：艾森克理论
Hans Eysenck proposed a biological theory of personality based on three major dimensions: extraversion–introversion, neuroticism–stability, and later added psychoticism. Each person’s personality can be described by where they fall on these continuous scales.
汉斯·艾森克提出了基于三个主要维度的人格生物学理论：外向–内向、神经质–稳定，后来还增加了精神质。每个人的性格都可以用他们在这些连续量表上的位置来描述。
Extraverts are sociable, outgoing, and crave excitement. Eysenck linked this to a low level of baseline arousal in the brain's reticular activating system, so they seek stimulation to bring arousal to an optimal level.
外向者善于交际、开朗且渴望刺激。艾森克将这与大脑网状激活系统的基线唤醒水平低联系起来，因此他们寻求刺激以将唤醒提升到最佳水平。
Introverts are quieter and prefer solitary activities. They have higher baseline arousal, so they avoid additional stimulation that could push arousal beyond comfort. This biological link shows how genetics influences personality.
内向者较安静，偏好独处活动。他们具有更高的基线唤醒水平，因此避免可能将唤醒推离舒适区的额外刺激。这种生物学联系展示了遗传如何影响人格。
Neuroticism refers to emotional instability. High scorers are prone to anxiety, moodiness, and stress, reacting more strongly to threats. This is linked to a more reactive sympathetic nervous system.
神经质指的是情绪不稳定性。高得分者容易焦虑、情绪化和压力，对威胁反应更强烈。这与更具反应性的交感神经系统有关。
Eysenck's theory is valuable because it is testable and has led to the development of widely used personality questionnaires (EPQ). However, it has been criticised for reducing personality to just a few traits and possibly oversimplifying human nature.
艾森克的理论很有价值，因为它可检验，并促进了广泛使用的人格问卷 (EPQ) 的发展。然而，它因将人格简化为少数几个特质并可能过度简化人性而受到批评。
12. Mental Health: Stress and Coping | 心理健康：压力与应对
Stress is the body's reaction to any demand or challenge. Psychologists distinguish between acute stress (short-term, such as an exam) and chronic stress (long-term, such as ongoing relationship problems). The physiological response involves activation of the sympathetic nervous system and release of hormones like adrenaline and cortisol.
压力是身体对任何需求或挑战的反应。心理学家区分急性压力（短期，如考试）和慢性压力（长期，如持续的关系问题）。生理反应涉及交感神经系统的激活以及肾上腺素和皮质醇等激素的释放。
The General Adaptation Syndrome (GAS), proposed by Hans Selye, describes three stages: alarm (the initial shock and mobilisation of resources), resistance (the body tries to adapt and cope), and exhaustion (resources are depleted, leading to illness if stress continues).
汉斯·塞利提出的一般适应综合征 (GAS) 描述了三个阶段：警戒期（初始冲击和资源调动）、抵抗期（身体试图适应和应对）和衰竭期（资源耗尽，如果压力持续会导致疾病）。
Coping strategies can be emotion-focused (managing emotional distress, e.g., seeking social support, relaxation) or problem-focused (tackling the source of stress directly, e.g., making a study timetable). A healthy balance is crucial.
应对策略可以是情绪导向的（管理情绪困扰，例如寻求社会支持、放松）或问题导向的（直接解决压力来源，例如制定学习时间表）。健康的平衡至关重要。
Chronic stress is linked to weakened immune function, cardiovascular disease, and mental health disorders such as anxiety and depression. Therefore, learning effective coping skills—such as mindfulness, exercise, and time management—is vital for well-being.
慢性压力与免疫功能减弱、心血管疾病以及焦虑和抑郁等心理健康障碍有关。因此，学习有效的应对技能——如正念、锻炼和时间管理——对身心健康至关重要。
In Year 8, you may explore how everyday stressors affect concentration and memory, highlighting the real-world relevance of stress research. Understanding personal stress triggers and building resilience can improve both academic performance and life satisfaction.
在 Year 8 阶段，你可能会探究日常压力源如何影响注意力和记忆，这凸显了压力研究在现实中的重要性。了解个人的压力触发点并建立心理韧性可以提升学业成绩和生活满意度。
