Effect of Contextual Motivation in Sports on the Evolution of Situational Intrinsic Motivation

The purpose of this study was to examine the evolution of participants’ situational motivation in physical activity. From a sample of 194 individuals, the 20 most self-determined, the 20 moderately self-determined, and the 20 least self-determined in sports were selected to participate in the research protocols. These 60 subjects performed a putting task with a golf club on a 1.50 m mat. Immediately afterward, they had to self-assess using the mouse paradigm software in order to measure their intrinsic situational motivation throughout the task. We used multilevel growth curve analyses (MGCAs) to explore the trajectories of students’ situational intrinsic motivation during the experimental task. The results revealed a significant positive linear and cubic effect of time and a significant negative quadratic effect of time on situational motivation for highly self-determined students. Our study shows that situational intrinsic motivation is dynamic, and the most self-determined subjects experience a positive evolution in their intrinsic motivation in a specific physical activity.
