The scientific study of the mind and behavior is called psychology. This discipline encompasses a broad range of topics, including mental processes, emotions, cognition, personality, and social interactions. Psychologists investigate how individuals think, feel, and act in various contexts, using both qualitative and quantitative research methods. The field has numerous sub-disciplines, such as developmental, clinical, cognitive, and social psychology, which explore different aspects of human experience. Through understanding behavior and mental processes, psychology aims to address issues related to mental health, enhance well-being, and improve interpersonal relationships.
