Although self-modeling has been effective in modifying behaviors in a variety of settings, little research has been completed in the physical domain. The purpose of this study was to test the effectiveness of self-modeling on performance and self-efficacy using a sport skill and to explore the cognitive processes underlying self-modeling. A multiple baseline single-subject design was used wherein five intermediate level volleyball players were given a self-modeling intervention. Performance outcome results indicated that self-modeling may contribute to increases in serve accuracy. Performance form and selfefficacy results were inconclusive. Using a think-aloud protocol, it was noted that although the participants found the images of themselves “shocking,” the images command cognitive resources. Postintervention interviews revealed that participants found the self-modeling intervention useful and that it led to changes in behavior and motivation.
