Elsevier are proud to introduce our brand new serial, Advances in Motivation Science. The topic of motivation has traditionally been one of the mainstays of the science of psychology. It played a major role in early dynamic and Gestalt models of the mind and it was fundamental to behaviorist theories of learning and action. The advent of the cognitive revolution in the 1960 and 70s eclipsed the emphasis on motivation to a large extent, but in the past two decades motivation has returned en force. Today, motivational analyses of affect, cognition, and behavior are ubiquitous across psychological literatures and disciplines; motivation is not just a hot topic on the contemporary scene, but is firmly entrenched as a foundational issue in scientific psychology. This volume brings together internationally recognized experts focusing on cutting edge theoretical and empirical contributions in this important area of psychology.
