Psychology is the scientific study of the mind and behavior. It encompasses a wide range of topics including how people think, feel, and act. It seeks to understand and explain thought processes, emotions, and actions through various approaches and schools of thought, such as cognitive, behavioral, clinical, social, and developmental psychology. Researchers and practitioners in psychology employ empirical methods to infer causal and correlational relationships between psychosocial variables. Additionally, psychologists use their understanding to help individuals, groups, and societies function better, which can include therapy and counseling for mental health issues.
