1. What is Psychology? | 什么是心理学？

Psychology is the scientific study of the mind and behaviour. Unlike everyday speculation, psychology relies on empirical evidence gathered through systematic observation, measurement, and experimentation. It investigates both observable actions (like talking or walking) and internal mental processes (like thinking, remembering, and feeling). The field has many branches, including cognitive psychology, developmental psychology, social psychology, and biological psychology, each focusing on different aspects of human experience.

心理学是对心理和行为的科学研究。与日常的猜测不同，心理学依赖于通过系统观察、测量和实验收集的实证证据。它既研究可观察的行为（如说话或行走），也研究内部的心理过程（如思考、记忆和感受）。心理学有许多分支，包括认知心理学、发展心理学、社会心理学和生物心理学，每个分支都关注人类经验的不同方面。

Psychologists apply the scientific method: they formulate a research question, propose a hypothesis, collect and analyse data, and draw conclusions. The key goals are to describe, explain, predict, and sometimes modify behaviour. For example, a psychologist might design an experiment to test whether listening to music improves concentration, then use the results to recommend study strategies.

心理学家运用科学方法：他们提出研究问题、假设、收集和分析数据，并得出结论。其主要目标是描述、解释、预测，有时也改变行为。例如，心理学家可能会设计一个实验，测试听音乐是否能提高注意力，然后用结果来建议学习策略。

2. Research Methods and Key Concepts | 研究方法与关键概念

Psychological research often uses experiments to establish cause-and-effect relationships. In an experiment, the researcher manipulates the independent variable (IV) to see its effect on the dependent variable (DV).
