Vansteenkiste, Simons, Lens, Sheldon, et al., 2004, Experiment 3: Teaching Tai-bo in an intrinsically or autonomous way increased learning and performance among Belgian high schoolers
Belgian high school students studied Tai-bo, a physical exercise, in class. For some the content was linked to their intrinsic goals for fitness and health. For others the content was linked to extrinsic goals for being physically attractive and avoiding gaining weight. Students in the intrinsic-goal condition learned more, performing better on Tai-bo exercises 3-5 days later, and were more likely to volunteer to demonstrate Tai-bo to other students and visitors several days later. Similar benefits were also found for an intervention that represented the course content in autonomy-supportive ways.
