Psychology is the study of the mind and behavior. Psychology is unique in that it is both a service-oriented health care profession and a field of scientific research. Hence, the roles of the psychologist are many—researcher, educator, licensed health care provider, and policy advocate. Psychologists are highly trained professionals—their education involves a median of 7 years of education and training beyond an undergraduate degree. What Is Geropsychology? Geropsychology is a field within psychology devoted to the study of aging and the provision of clinical services for older adults. As researchers, geropsychologists expand knowledge of the normal aging process and design and test psychological interventions that address problems that commonly arise as people age. As health care practitioners, psychologists help older persons and their families overcome problems, enhance well-being, and achieve maximum potential during later life.
