A psychologist is a professional who studies the mind and behavior. They help people understand their thoughts, feelings, and actions, often using various techniques to promote mental well-being. Psychologists can work in different settings, such as schools, hospitals, or private practices, and may specialize in areas like clinical psychology, counseling psychology, or developmental psychology. To become a psychologist, individuals typically need a graduate degree in psychology and must be licensed to practice in their region. They may conduct assessments, provide therapy, and engage in research to better understand human behavior. Psychologists often collaborate with other professionals, such as psychiatrists and social workers, to support their clients.
