pre-psychology in Culture

psychology

The science dealing with mental phenomena and processes. Psychologists study emotions, perception, intelligence, consciousness, and the relationship between these phenomena and processes and the work of the glands and muscles. Psychologists are also interested in diseased or disordered mental states, and some psychologists provide therapy for individuals. In the United States, however, psychologists, unlike psychiatrists, are not medical doctors. (See psychiatry.)

Note

The two main divisions of psychology are individual or personality psychology and social psychology; social psychology deals with the mental processes of groups.
