iv THE SCIENTIFIC MONTHLY-ADVERTISEMENTS

Books by Prof. Knight Dunlap

Elements of Scientific Psychology Professor Dunlap presents the accepted substance of psychology, clearing away many

of the confusing dogmas of the various "schools." which, in the past, have made psychology appear to the layman to be a mass of arbitrary and conflicting "isms." Starting from the fact that the individual is primarily an organism for response, or adjustment to its environ- ment, the relation between consciousness and the responses is explained without any psycho- logical assumption beyond the known connection of sense-organ with muscle and gland, and the well-established tendency of the nervous system to "integrate," or function as a whole. Habit formation is thus shown to be the basis for the development of mental life; and every art of thinking, perceiving, and feeling, as well as every outward activity, is definitely connected with neural integration. The elimination of vague assumption of mysterious brain activities is a distinct advance in textbook construction. 368 pages, 31 illustrations. Postpaid, $3.50.

Old & New Viewpoints Mysticism, Freudianism in Psychology & Scientific Psychology
