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.

This series brings together internationally recognized experts who focus on cutting-edge theoretical and empirical contributions in this important area of psychology.
