Vansteenkiste, Simons, Lens, Sheldon, et al., 2004, Experiment 3: Teaching Tai-bo in an autonomous or intrinsic way increased performance and volunteering among Belgian high school students 3-5 days later
Belgian high school students studied Tai-bo, a physical exercise, in class. For some the instructions used autonomy-supportive phrases while for others, the instructions used controlling phrases, as in Vansteenkiste, Simons, Lens, Sheldon et al. (2004) Experiments 1 and 2. Students in the autonomy-supportive 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 as linked to students’ intrinsic fitness goals.
