ABSTRACT
Gregory Kimble's functional behaviorism and Arthur Staats' psychological behaviorism both ground on the behavioristic tradition. Norman Anderson's information integration theory (IIT) is derived from the cognitive psychology tradition and the information processing theory. Gregg Henriques' unified theory of psychology is a sort of meta-theory that eclectically frames concepts from different theories and research programs. On the trail of Newton's laws of motion, Kimble tries to portray psychology's contour on the basis of relatively few theoretical principles. In his 1996 book, Psychology: The Hope of a Science, Gregory Kimble intends to reach the goal of the unification of psychology from a radical behavioristic perspective. Finally, Robert Sternberg and colleagues' proposal of unified psychology, starting from methodological and theoretical issues, deals with practical and institutional problems of organization in psychology, which is considered both as a science and as a profession.
