Motion Pictures as an Aid in Correcting Baseball Batting Faults
David L. Watkins · Research Quarterly American Association for Health Physical Education and Recreation · 1963
The purpose of this study was to determine the effectiveness of motion pictures as an instructional aid in the correcting of batting faults in baseball. Twenty subjects from the varsity baseball squad at the State University of Iowa served as subjects and were divided into a control group and an experimental group. The findings would appear to warrant the conclusion that baseball players who view motion pictures of their batting can significantly decrease the number of their batting faults as compared to baseball players who do not view motion pictures of their batting.
