Psychology is the scientific study of the mind and behavior. It encompasses a broad range of topics, from the workings of the brain to the influence of social interactions on individual actions. As a discipline, psychology seeks to understand how people perceive, think, feel, and act both individually and in groups. Through various subfields such as cognitive, developmental, social, and clinical psychology, researchers and practitioners strive to uncover the underlying mechanisms of mental processes and behavior. By applying this knowledge, psychology aims to improve mental health, enhance education, optimize work environments, and address numerous other societal challenges.
