1. What is Psychology? | 什么是心理学？

Psychology is defined as the scientific study of the mind and behaviour. It examines both observable actions and internal mental processes such as thinking, memory, and emotions. Psychologists use empirical evidence gathered through research to develop theories about human functioning.

心理学被定义为对心智和行为的科学研究。它考察可观察的行动以及思维、记忆和情感等内部心理过程。心理学家利用通过研究收集的经验证据来发展关于人类功能的理论。

The discipline is divided into several branches, including cognitive psychology (how we process information), developmental psychology (how we grow and change across the lifespan), social psychology (how we interact with others), and biological psychology (the links between brain and behaviour).

该学科分为多个分支，包括认知心理学（我们如何处理信息）、发展心理学（我们在整个生命周期中如何成长和变化）、社会心理学（我们如何与他人互动）以及生物心理学（大脑与行为之间的联系）。

Psychology is applied in everyday life, from improving learning strategies in schools to designing user-friendly technology. Understanding psychological principles can help people build better relationships, manage stress, and make informed decisions.

心理学被应用于日常生活，从改进学校的学习策略到设计用户友好的技术。理解心理学原理可以帮助人们建立更好的人际关系、管理压力并做出明智的决定。

2. Research Methods in Psychology | 心理学研究方法

Psychologists use a variety of research methods to test hypotheses. The most controlled method is the experiment, where a researcher manipulates an independent variable (IV) to measure its effect on a dependent variable (DV), while keeping other factors constant. For example, you might test whether background music (IV) affects memory recall (DV).

心理学家使用多种研究方法来检验假设。最受控制的方法是实验，实验中研究者操纵自变量 (IV)，测量它对因变量 (DV) 的影响，同时保持其他因素不变。例如，你可以测试背景音乐（IV）是否影响记忆回忆（DV）。

Other common methods include observations (watching and recording behaviour in natural or controlled settings) and questionnaires (collecting self-report data from many participants). Ethical guidelines are crucial: researchers must obtain informed consent, protect participants from harm, and allow them to withdraw at any time.

其他常见的方法包括观察法（在自然或受控环境中观察并记录行为）和问卷法（从众多参与者那里收集自我报告数据）。伦理准则至关重要：研究者必须获得知情同意，保护参与者免受伤害，并允许他们随时退出。

3. Memory: How We Remember | 记忆：我们如何记忆

Memory involves three key processes: encoding (transforming sensory input into a form that can be stored), storage (keeping information over time), and retrieval (accessing stored information when needed). The multi-store model suggests that memory consists of sensory memory, short-term memory (STM), and long-term memory (LTM).

记忆涉及三个关键过程：编码（将感觉输入转化为可存储的形式）、存储（随时间保留信息）和提取（在需要时访问已存储的信息）。多存储模型认为，记忆由感觉记忆、短时记忆 (STM) 和长时记忆 (LTM) 组成。

Sensory memory holds information for a fraction of a second. STM can hold about 7±2 items for around 18–30 seconds if we do not rehearse. Through rehearsal, information can move into LTM, which has a potentially unlimited capacity and duration. Forgetting can occur due to decay or interference from other memories.

感觉记忆将信息保持几分之一秒。如果不进行复述，STM 可以保留大约 7±2 个项目，时长约 18–30 秒。通过复述，信息可以转入 LTM，LTM 的容量和持续时间几乎是无限的。遗忘可能由于痕迹消退或来自其他记忆的干扰而发生。

Interference theory suggests that forgetting in LTM occurs when information is confused with other memories. Proactive interference is when old memories disrupt recall of new ones, while retroactive interference is when new memories disrupt recall of old ones.

干扰理论认为，LTM 中的遗忘发生在信息与其他记忆混淆时。前摄干扰是指旧记忆干扰对新信息的回忆，而倒摄干扰是指新记忆干扰对旧信息的回忆。

4. Attachment: Bonding with Caregivers | 依恋：与照料者的纽带

Attachment is the deep emotional bond that develops between an infant and their primary caregiver, usually the mother. John Bowlby proposed that attachment is an innate system that promotes survival, and that the quality of early attachment forms an internal working model for future relationships.

依恋是婴儿与其主要照料者（通常是母亲）之间形成的深厚情感纽带。约翰·鲍尔比提出，依恋是一种促进生存的先天系统，早期依恋的质量会形成对未来关系的内部工作模型。

Mary Ainsworth developed the Strange Situation procedure to assess attachment styles. She identified secure attachment (the child explores happily when the caregiver is present and is comforted on reunion), insecure-avoidant attachment (the child ignores the caregiver), and insecure-resistant attachment (the child is clingy yet resists comfort). Secure attachment is associated with better social and emotional outcomes.

玛丽·安斯沃斯设计了陌生情境程序来评估依恋类型。她识别出安全型依恋（照料者在场时孩子愉快地探索，重聚时得到安慰）、不安全-回避型依恋（孩子忽视照料者）和不安全-矛盾型依恋（孩子粘人但又拒绝安慰）。安全型依恋与更好的社交和情感结果相关。

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 line-judgment experiments showed that people often conform to an obviously incorrect majority to avoid feeling different or being rejected.

从众是指由于真实或想象到的群体压力而导致行为或信念的改变。所罗门·阿希的线条判断实验表明，人们经常会遵从明显错误的多数人意见，以避免感觉与众不同或被排斥。

Obedience involves following direct commands from an authority figure. Stanley Milgram’s studies revealed that ordinary people might deliver what they believed were dangerous electric shocks to another person when instructed by an authority in a lab coat. The bystander effect describes the tendency for individuals to be less likely to help in an emergency when other people are present, due to diffusion of responsibility.

服从涉及听从权威人物直接的指令。斯坦利·米尔格拉姆的研究揭示，当身穿实验室白大褂的权威人物下达指令时，普通人可能会对他人施加他们认为危险的电击。旁观者效应描述了当有他人在场时，个体在紧急情况下提供帮助的可能性降低的现象，这是由于责任扩散所致。

6. Cognitive Development: Piaget’s Theory | 认知发展：皮亚杰理论

Jean Piaget proposed that children actively construct their understanding of the world through schemas (mental frameworks). Two processes drive cognitive development: assimilation (fitting new information into existing schemas) and accommodation (changing schemas to fit new information).

让·皮亚杰提出，儿童通过图式（心理框架）主动建构对世界的理解。有两个过程驱动着认知发展：同化（将新信息纳入现有图式）和顺应（改变图式以适应新信息）。

Piaget outlined four stages of cognitive development. The sensorimotor stage (0–2 years) features object permanence—the understanding that objects continue to exist even when out of sight. The preoperational stage (2–7 years) is marked by egocentrism and a lack of conservation (knowing that quantity stays the same despite changes in appearance). In the concrete operational stage (7–11 years), children master conservation and logical thinking about concrete events. The formal operational stage (11+ years) brings abstract and hypothetical reasoning.

皮亚杰概述了认知发展的四个阶段。感觉运动阶段（0–2 岁）的特点是客体永久性——理解物体即使看不见也仍然存在。前运算阶段（2–7 岁）以自我中心和缺乏守恒（知道数量不随外观改变而变化）为标志。在具体运算阶段（7–11 岁），儿童掌握守恒并能对具体事件进行逻辑思考。形式运算阶段（11 岁以上）带来了抽象和假设推理能力。

7. The Brain and Behaviour | 大脑与行为

The human brain is the control centre for all behaviour. The cerebral cortex, the brain’s outer layer, is responsible for higher functions such as language
