The popular conception of a psychologist is someone who provides therapy,
like the television character Frasier Crane (see below-left picture).
Dr. Crane is actually not a psychologist, but a psychiatrist, someone who
receives their doctoral education in general medicine and who then specializes
in the treatment of mental disorders. While clinical psychologists, like
psychiatrists, do provide therapy, there are many other types of psychologists
who do not engage in therapy, such as industrial psychologists, social
psychologists, cognitive psychologists, and physiological psychologists,
just to name a few.
In the July 1995 edition of the American Psychologist, Domjan and Purdy
pointed out that a great deal of research in psychology is conducted with
laboratory animals, like the rat in the below-right picture.
