1650s, "study of the soul," from Modern Latin psychologia, probably coined mid-16c. in Germany by Melanchthon from Latinized form of Greek psykhe- "breath, spirit, soul" (see psyche) + logia "study of" (see -logy). Meaning "study of the mind" first recorded 1748, from Christian Wolff's "Psychologia empirica" (1732); main modern behavioral sense is from early 1890s.
psychology psy·chol·o·gy (sī-kŏl'ə-jē)
The science that deals with mental processes and behavior.
The emotional and behavioral characteristics of an individual, a group, or an activity.
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.
