Psychologists study human behavior and mental processes to understand, explain, and change people’s behavior. Psychologists specialize in many different areas. Clinical Psychologists, who constitute the largest specialty, generally work in independent or group practices or in hospitals and clinics. They may help the mentally or emotionally disturbed adjust to life and are increasingly helping all kinds of medical and surgical patients to deal with their illness or injuries. Health Psychologists promote good health through health maintenance counseling programs that are designed, for example, to help people stop smoking or lose weight.
An applicant for a license to practice as a psychologist must be at least 19 years of age, have a doctorate degree from an accredited program of graduate study in professional psychology, complete two years of supervised professional experience, and pass the national standardized examination.
