Self-Determination Theory (SDT) is a theory of motivation. It is concerned with supporting our natural or intrinsic tendencies to behave in effective and healthy ways. SDT has been researched and practiced by a network of researchers around the world.
The theory was initially developed by Edward L. Deci and Richard M. Ryan at the University of Rochester, and has been elaborated and refined by scholars from many countries. Deci and Ryan are professors in the Department of Clinical and Social Sciences in Psychology at the University of Rochester, where they direct a pre- and post-doctoral training program focused on SDT.
This website presents a brief overview of SDT and provides resources that address important issues such as human needs, values, intrinsic motivation, development, motivation across cultures, individual differences, and psychological well-being.
