“…One of the most important theories of motivation as a predictor of academic performance, but also of well-being (Reid et al, 2019) is the Self-Determination Theory (SDT), formulated by Deci and Ryan in 1985(1985, cited in Alt, 2015bClark & Schroth, 2010;Noyens et al, 2019;Smith et al, 2020). Unlike previous theories, which present a structure of motivation with two factors: motivated behavior and lack of motivation, the theory of self-determination proposes a more complete understanding of the concept and argues that in the case of motivated behavior we can talk about two other motivating factors: intrinsic motivation and extrinsic motivation (Alt, 2015a;Clark & Schroth, 2010;Joe et al, 2017;Kindelberger et al, 2019;Öz, 2016;Smith et al, 2020). The authors of this theory consider that for each individual the behavior is determined by a combination of the two types of motivations, intrinsic and extrinsic (Henderson-King & Smith, 2006).…”
