“…In recent decades, researchers from different fields, such as psychology, rehabilitation, therapy, special education and adapted physical activity, recognized that among the factors contributing to the daily expression of a disability, a prominent role is played by the individual's innate development forces (Ryan & Deci, 2017). Accordingly, people are organismically predisposed to self-organization, self-regulation, and self-determination, in order to meet their basic biological and psychological needs (Shogren & Wehmeyer, 2016). Therefore, cognitive-affective processes, such as aspiration formation, self-determined choice, sense of volition, intentional planning, goal-setting, problem-solving, self-observation, and self-evaluation, are being strongly connected to effective learning and skills acquisition (e.g., Cleary, Callan, & Zimmerman, 2012;Murayama et al, 2013;Palisano et al, 2011;Saebu, Sørensen, & Halvari, 2013;Wehmeyer, Yeager, Bolding, Agran, & Hughes, 2003).…”
