Self-Determination Theory in Positive Psychology
Self-Determination Theory is one of the most important frameworks in positive psychology because it explains flourishing through the quality of motivation rather than through reward alone. This article examines the origins of SDT, its organismic view of human development, the distinction between intrinsic and extrinsic motivation, and the central role of autonomy, competence, and relatedness as basic psychological needs. It also explores internalization, need-supportive environments, and applications across education, work, and health. The result is a stronger account of SDT as a theory not only of motivation, but of the social and institutional conditions under which human beings are most likely to act with volition, mastery, and connection.
