Expecting to teach enhances motor learning and information processing during practice

Abstract

Recent research has revealed that having learners study and practice a motor skill with the expectation of having to teach it enhances motor learning. However, the mechanisms underlying this effect remain unknown. We attempted to replicate this effect and elucidate the mechanisms underlying it. Thus, participants studied golf putting instructions and practiced putting either with the expectation of having to teach another participant how to putt or the expectation of being tested on their putting. During this acquisition phase, participants' motivation, anxiety, and information processing (the duration they took preparing each putt) were indexed as possible mechanisms underlying a motor learning effect. One day and seven days after the acquisition phase, learning was assessed by testing all participants on their golf putting. Results revealed that expecting to teach enhanced motor learning, replicating the original finding. Moreover, expecting to teach increased the duration participants took preparing each putt, which was correlated with superior motor learning. Thus, results suggest expecting to teach enhances motor learning by increasing information processing during practice.
