This chapter first examines different interpretations of the term "psychology" and argues that practical teachers want a psychology that will work. In short, we propose to treat the various schools of Psychology as so many hypotheses — which, after all, is probably not far from the truth — and to select that school which promises to be most useful in meeting our needs. We shall then pass in review before us the various systems with the deliberate purpose of selecting that which suits our purpose. (PsycINFO Database Record (c) 2016 APA, all rights reserved)
