(Deci & Ryan, 1985) SDT is a theory of motivation that is built on the assumption that humans have innate tendencies to move in directions of greater self-regulation, competence, and integration in action. This process is dependent on the support and fulfilment of three basic psychological needs: competence, relatedness, and autonomy. In the 1970s, research on SDT evolved from studies comparing the intrinsic and extrinsic motives, and from a growing understanding of the dominant role intrinsic motivation played in an individual’s behavior. Before this understanding, SDT was formally introduced and accepted as a sound empirical theory. Research applying SDT to different areas in social psychology has definitely increased considerably since the 2000s. Overall the studies, the results showed that the most self-determined forms of motivation (intrinsic motivation and identified regulation) were related more strongly to determinants such as autonomy support from coaches and feelings of competence than to other forms of motivation (external and introjected regulation) and
