The problem of education is at the very heart of the new psychology. The study of conditional reflexes constitutes a foundation on which the new psychology will have to be constructed. There's no denying the fact that educational psychology, as a science, became possible only with this discovery. Now, the most important goal of the present monograph is to maintain such a fundamentally rational unity in the analysis of all the various aspects of education and in the description of the different elements of the instructional process. It is of extraordinary importance to demonstrate with exhaustive scientific rigor that, no matter what its subject matter and no matter what its methodology, at its very foundation education ultimately always rests upon the mechanism of the conditional reflex.
