1. What is Psychology? | 什么是心理学？
Psychology is defined as the scientific study of mind and behaviour. It uses systematic methods to observe, measure, and analyse how people act and think. The main goals are to describe, explain, predict, and sometimes change behaviour. For instance, psychologists investigate why we forget, why people obey authority, and how personality develops.
心理学被定义为对心理和行为的科学研究。它使用系统的方法来观察、测量和分析人类的行为与思维。其主要目标是描述、解释、预测并在某些情况下改变行为。例如，心理学家研究我们为何会遗忘、人们为何服从权威以及人格如何发展。
Psychology is a broad discipline that covers many areas, including developmental psychology (how we grow), social psychology (how we interact), cognitive psychology (how we think), and biological psychology (the brain and body). Each area uses scientific evidence, not just intuition or common sense.
心理学是一门涵盖多个领域的广泛学科，包括发展心理学（我们如何成长）、社会心理学（我们如何互动）、认知心理学（我们如何思考）以及生物心理学（大脑与身体）。每个领域都依赖科学证据，而不仅仅是直觉或常识。
2. Key Approaches in Psychology | 心理学主要流派
The biological approach explains behaviour through brain structures, genes, and hormones. For example, it links aggression to the amygdala or certain neurotransmitters. This approach highlights the physical basis of our thoughts and actions.
生物流派通过大脑结构、基因和激素来解释行为。例如，它将攻击性与杏仁核或某些神经递质联系起来。这一流派强调思维与行为的生理基础。
The cognitive approach focuses on mental processes like memory, attention, and problem-solving. It compares the mind to a computer that inputs, processes, and outputs information. This helps explain why we remember some things but forget others.
认知流派专注于记忆、注意力和问题解决等心理过程。它将心智比作一台输入、处理和输出信息的计算机。这有助于解释为何我们会记住一些事情而忘记另一些。
The behavioural approach studies observable actions and how the environment shapes them through learning. Key ideas include classical conditioning (learning by association) and operant conditioning (learning by consequences). This approach shows that much of our behaviour is acquired through experience.
行为流派研究可观察的行为以及环境如何通过学习来塑造它们。核心理念包括经典条件作用（通过联想学习）和操作性条件作用（通过后果学习）。这一流派表明，我们的许多行为都是通过经验习得的。
3. Research Methods: An Introduction | 研究方法入门
Experiments are the most powerful method for identifying cause and effect. A researcher manipulates an independent variable (IV) and measures its effect on a dependent variable (DV) while controlling other factors. For example, a memory experiment might vary the type of material (IV) and measure recall accuracy (DV).
实验是确定因果关系最有力的方法。研究者操纵自变量（IV），测量其对因变量（DV）的影响，同时控制其他因素。例如，一项记忆实验可以改变材料类型（IV）并测量回忆的准确性（DV）。
Other research methods include observations, where behaviour is recorded in natural or controlled settings, and surveys or interviews, which gather self-reported data. Each method has strengths and limitations, so psychologists often use more than one to check findings.
其他研究方法包括观察法（在自然或控制环境中记录行为）以及调查和访谈（收集自我报告数据）。每种方法都有其优缺点，因此心理学家通常使用多种方法来验证结果。
All psychological research must follow ethical guidelines. Participants must give informed consent, know they can withdraw at any time, and have their data kept confidential. Researchers also have a duty to protect participants from physical or psychological harm.
所有的心理学研究都必须遵循道德准则。参与者必须知情同意，知道他们可以随时退出，并且其数据需保密。研究者还有责任保护参与者免受身心伤害。
4. Memory: How We Remember | 记忆：我们如何记忆
The multi-store model describes memory as three separate stores: sensory memory, short-term memory (STM), and long-term memory (LTM). Information flows from the senses into sensory memory, where it lasts only a fraction of a second. If we pay attention, it moves to STM.
多贮存模型将记忆描述为三个独立的存储库：感觉记忆、短时记忆（STM）和长时记忆（LTM）。信息从感官进入感觉记忆，在那里只持续几分之一秒。如果我们加以注意，它就会进入短时记忆。
STM has a limited capacity of about 7 plus or minus 2 chunks of information and a duration of around 18–30 seconds without rehearsal. Rehearsal helps transfer information into LTM, which has a potentially unlimited capacity and can last a lifetime.
短时记忆的容量有限，约为7±2个组块，若不加复述，持续时间约为18至30秒。复述有助于将信息转入长时记忆，长时记忆的容量几乎没有限制，且可以持续终生。
| Feature | Short-Term Memory | Long-Term Memory |
|---|---|---|
| Capacity | Limited (7±2 chunks) | Potentially unlimited |
| Duration | Around 18–30 seconds | Up to a lifetime |
| Encoding | Mainly acoustic (sound) | Mainly semantic (meaning) |
Forgetting can occur because of decay (memory trace fades over time) or interference (new or old information disrupts recall). The serial position effect shows that we remember items at the beginning (primacy) and end (recency) of a list best, supporting the idea of separate stores.
遗忘可能由于衰退（记忆痕迹随时间消退）或干扰（新旧信息扰乱回忆）而发生。系列位置效应表明，我们对列表开头（首因效应）和末尾（近因效应）的项目记忆最好，这支持了存在独立存储库的观点。
5. Social Influence: Conformity and Obedience | 社会影响：从众与服从
Conformity is a change in behaviour or belief as a result of real or imagined group pressure. Solomon Asch’s classic study showed that people often agree with an incorrect majority judgement about line lengths, even when the correct answer is obvious. Many participants conformed to avoid standing out.
从众是指由于真实或想象中的群体压力而导致的行为或信念改变。所罗门·阿希的经典研究表明，人们经常会同意大多数人对线条长度做出的错误判断，即使正确答案显而易见。许多参与者为了避免显得与众不同而选择从众。
There are two main types of social influence: normative influence (wanting to be liked and accepted) and informational influence (wanting to be right and looking to the group for guidance). Both help explain why we sometimes go along with the crowd.
社会影响主要有两种类型：规范型影响（想要被喜欢和接纳）和信息型影响（想要正确并依赖群体指导）。这两者都有助于解释我们为什么有时会随大流。
Obedience involves following direct commands from an authority figure. Stanley Milgram’s famous experiment revealed that ordinary people could deliver what they believed were painful electric shocks to another person when told to do so by an experimenter. Factors such as the authority’s closeness and legitimacy affect obedience levels.
服从涉及听从权威人物的直接命令。斯坦利·米尔格拉姆的著名实验揭示，普通人在实验者的指令下，可以对另一个人施加他们认为痛苦的电话。权威的亲近程度和合法性等因素会影响服从水平。
6. Brain and Behaviour: The Biological Basis | 大脑与行为：生物基础
The cerebral cortex is divided into four lobes, each with specific functions. The frontal lobe is involved in thinking, planning, and personality; the temporal lobe processes hearing and memory; the parietal lobe handles touch and spatial awareness; and the occipital lobe is dedicated to vision.
大脑皮层分为四个叶，每个叶都有特定的功能。额叶参与思维、计划和人格；颞叶负责处理听觉和记忆；顶叶负责触觉和空间意识；枕叶则专门负责视觉。
Neurons are nerve cells that communicate through electrical and chemical signals. Each neuron has dendrites that receive messages, a cell body, and an axon that sends signals to other neurons across a tiny gap called the synapse. Neurotransmitters are the chemical messengers released into the synapse.
神经元是通过电信号和化学信号进行通信的神经细胞。每个神经元都有接收信息的树突、一个细胞体，以及将信号通过名为突触的微小间隙发送给其他神经元的轴突。神经递质是释放到突触中的化学信使。
Localisation of function means that specific brain areas control particular abilities. Broca’s area, in the left frontal lobe, is vital for speech production, while Wernicke’s area, in the left temporal lobe, is crucial for understanding language. Damage to these areas can lead to specific language difficulties.
功能定位意味着特定的大脑区域控制着特定的能力。位于左额叶的布罗卡区对言语产生至关重要，而位于左颞叶的韦尼克区对理解语言至关重要。这些区域受损会导致特定的语言障碍。
7. Developmental Psychology: Piaget’s Stages | 发展心理学：皮亚杰的阶段理论
Jean Piaget proposed that children go through four stages of cognitive development. The sensorimotor stage (0–2 years) involves learning through senses and actions. The preoperational stage (2–7 years) sees the development of language and imagination, but children are egocentric and struggle with conservation.
让·皮亚杰提出，儿童会经历四个认知发展阶段。感知运动阶段（0–2岁）通过感官和动作学习。前运算阶段（2–7岁）语言和想象力得到发展，但儿童以自我为中心，并且难以掌握守恒概念。
The concrete operational stage (7–11 years) is when children begin to think logically about concrete events. They can understand conservation (e.g., the amount of liquid stays the same despite changes in container shape), classify objects, and see other viewpoints. Most Year 7 students are in this stage or entering the next.
具体运算阶段（7–11岁）儿童开始对具体事件进行逻辑思考。他们能够理解守恒（例如，无论容器形状如何变化，液体的量保持不变）、分类物体并能从他人角度看问题。大多数Year 7学生正处于这一阶段或即将进入下一阶段。
In the formal operational stage (11+ years), abstract and hypothetical thinking emerges. Teenagers can reason about possibilities, plan systematically, and think about moral and philosophical issues. Piaget’s work highlights that children are not simply less knowledgeable adults, but think in qualitatively different ways.
在形式运算阶段（11岁以上），抽象和假设性思维出现。青少年能够对可能性进行推理、系统地规划，并思考道德和哲学问题。皮亚杰的研究强调，儿童并非只是知识较少的成人，而是以质上不同的方式进行思考。
8. Sensation and Perception | 感觉与知觉
Sensation is the process by which our sensory receptors detect physical energy from the environment, such as light, sound, or pressure. Perception is the brain’s active interpretation and organisation of these sensory signals, giving them meaning. We sense colours, but we perceive a painting.
感觉是我们的感觉感受器探测环境中物理能量（如光、声、压力）的过程。知觉是大脑对这些感觉信号进行主动的阐释和组织并赋予其意义的过程。我们感觉到颜色，但我们感知到一幅画。
Visual illusions demonstrate that perception is not always accurate. The Muller-Lyer illusion, where two lines of equal length appear different because of arrow-like fins, and the Ponzo illusion, where an upper line looks longer due to converging lines, show how context and depth cues trick our brain.
视错觉表明知觉并不总是准确的。缪勒-莱耶错觉（两条等长线条因箭头状翼而显得不同）和庞佐错觉（上方线条因会聚线而显得更长）显示了情境和深度线索如何欺骗我们的大脑。
Perception involves both bottom-up processing (building a whole from sensory details) and top-down processing (using prior knowledge and expectations to interpret incoming information). Together, they help us recognise objects, read, and navigate the world quickly.
知觉既包括自下而上的加工（从感觉细节构建整体），也包括自上而下的加工（利用先验知识和期望解释传入的信息）。两者协同帮助我们快速识别物体、阅读和在世界中行动。
9. Mental Health and Wellbeing | 心理健康与幸福感
Mental health refers to our emotional, psychological, and social well-being. It affects how we think, feel, and handle stress. Positive mental health is not simply the absence of illness; it enables us to enjoy life, maintain relationships, and cope with challenges.
心理健康指我们的情绪、心理和社会幸福感。它影响我们的思维、感受以及应对压力的方式。积极的心理健康不仅仅是没有疾病，它使我们能够享受生活、维持人际关系并应对挑战。
Common mental health concerns in young people include stress, anxiety, and low mood. These can be triggered by school pressures, friendship difficulties, or family changes. Healthy coping strategies include talking to a trusted adult, practising mindfulness, exercising regularly, and maintaining a balanced routine.
青少年常见的心理健康问题包括压力、焦虑和情绪低落。这些可能由学业压力、交友困难或家庭变化引发。健康的应对策略包括与信赖的成人交谈、练习正念、规律锻炼以及保持平衡的日常作息。
Reducing stigma around mental health is important. Understanding that mental health difficulties are real, common, and treatable encourages people to seek help. Open conversations and education make it easier to challenge stereotypes and build a supportive community.
减少围绕心理健康的污名化非常重要。理解心理健康问题是真实、常见且可治疗的，会鼓励人们寻求帮助。开放的对话和教育有助于挑战刻板印象，建立支持性的社群。
10. Psychological Skills: Critical Thinking | 心理学技能：批判性思维
Critical thinking in psychology means evaluating evidence rather than accepting claims at face value. This involves questioning the validity (whether a study measures what it intends) and reliability (whether results can be replicated) of research. Strong critical thinkers look for biases and alternative explanations.
心理学中的批判性思维意味着评估证据，而不是盲目接受说法。这包括质疑研究的效度（研究是否测量了它想要测量的东西）和信度（结果是否可重复）。强大的批判性思考者会寻找偏见和其他解释。
Recognising bias is a key skill. For example, cultural bias may occur if studies only use participants from one culture and assume findings apply to everyone. Gender bias and researcher bias can also distort results. Being aware of these pitfalls improves the quality of psychological science.
识别偏见是一项关键技能。例如，如果研究只使用来自一种文化的参与者并假设结果适用于所有人，就可能发生文化偏见。性别偏见和研究者偏见也会歪曲结果。意识到这些陷阱可以提高心理学研究的质量。
Applying psychological knowledge to everyday life helps you think more clearly about your own behaviour and that of others. For instance, understanding memory strategies can improve your revision, and knowing about social influence makes you more aware of group pressures. Psychology is not just a school subject—it is a toolkit for life.
将心理学知识应用于日常生活，有助于你更清晰地思考自己和他人的行为。例如，了解记忆策略可以提升你的复习效果，认识社会影响会使你更清楚群体压力。心理学不仅是一门学校科目，它还是一套生活的工具箱。
