Anatomy and the Problem of Behavior.

Professor Coghill delivered these lectures before the University of London, an honor paid to few American scientists. In itself it is an expression of the high regard in which Coghill's work is held. The problem consisted in making parallel studies of the development of behavior and the development of the nervous system. It seemed to him "basic to a scientific study of behavior to know whether the behavior pattern of an animal develops haphazard or in an orderly manner; and that, if it should be found that behavior develops in an orderly manner, then there should be a corresponding order of development structurally and functionally in the nervous system." This question was taken up in the first lecture. TheAmblystomawas found to be a splendid animal for this purpose. In brief, Coghill found that "the behavior pattern develops in a regular order of sequence of movements, which is consistent
