Abstract: The use of video cameras and technology to augment motor learning is highly prevalent, yet empirical evidence for the effectiveness of visual feedback in motor skill acquisition has not been demonstrated. In this investigation, a meta-analysis was conducted to determine the influence of visual feedback on motor learning. All available studies testing the utility of visual feedback were coded and meta-analyzed. A comparison was made between participants learning a motor skill with verbal feedback compared to participants learning with verbal and visual feedback. Overall, the weighted mean effect size of visual feedback was (.21) demonstrating a small effect. Implications for theory, practice, and policy are discussed.
