In a study of healthy young adults learning a motor skill, teaching was found to be much more effective if instruction was given from the student’s point-of-view (1st person perspective) rather than the instructor’s (3rd person perspective). In the 3rd person perspective, a student must ‘flip’ what he or she sees, and that takes more brain work as well as results in more errors. 90% of the errors resulted from the 3rd person perspective.
