The Fundamentals of Learning
This volume reports investigations covering a period of three years, dealing with the fundamental facts and forces in learning. It was the author's original purpose to work at certain basic problems until satisfactory solutions were reached; and in general he has done so. But the results suggested certain new problems of such great importance that he has thought it wise to study these also, even without expectation of attaining a final settlement of them. As an indirect consequence of this, one important problem in his original set, that of the relation of the formation of conditional reflexes to associative shifting of the ordinary sort, has been treated only very cursorily.
