Psychology is the scientific study of the mind and behavior. It seeks to understand how people think, feel, and act both individually and in groups. The field encompasses various aspects, including mental processes, emotions, personality, and social interactions. Psychologists use empirical methods to observe, describe, predict, and sometimes intervene in mental and behavioral processes.
