What happens when you watch yourself perform in VR—and then have to critique that performance? This study explored self-reflection in motor skill learning using a Karate training task. Participants were embodied as a "trainer" avatar and asked to give verbal feedback on a "trainee"—which was either their own 3D-scanned appearance or a stranger, performing either their own recorded movements or an expert's. The results revealed a psychological "role conflict": participants felt split between being the evaluator and being evaluated. Seeing their own appearance triggered deeper, more emotional reflection, while recognizing their own movements created bodily connection even in a stranger's avatar. The findings suggest VR embodiment isn't binary but multi-faceted, with implications for training and therapy.
