Verbal Instruction for Correcting Errors versus Such Instructions Plus Videotape Replay on Learning the Overhand Throw

Abstract

The influence of two methods of providing information to women, ages 19 to 22 years who were novices and learning the overhand throw with the non-dominant arm, was examined. One group received verbal information on correcting errors, and a second group received the same information immediately prior to viewing a videotaped replay of a just-completed throw. Performance was assessed quantitatively with respect to outcome (distance thrown) and qualitatively with respect to throwing form as measured on a 7-point rating scale by judges with a working knowledge of the overhand throw and with respect to throwing mechanics rated by a panel of experts in biomechanics using a scale of Leme and Shambes. Although the treatments led to better learning and performance, there was no significant difference between groups for distance thrown on the Leme and Shambes scale in Sessions 1–6 of 10 trials each on Session 7. The mean rating also indicated increased scores for both groups and better retention at posttest by the group receiving only verbal corrections. These results suggest that information provided by adding videotaped replay may be redundant and unnecessary for those in Sessions 1–6.
