I am interested in human motivation, particularly the nature and development of self-determination.
I examine a variety of issues in human motivation, isolating basic processes and testing their application to education, health care, parenting, mental health, and work organizations in the US and across cultures. Using both laboratory and field methods, my work focuses primarily on the nature and development of self-determination. For more detail, please see the Self-Determination Theory website.
