Examining Learner-Controlled Role-Switching in Dyad Practice for the Learning of a Speed Cup-Stacking Task.

Dyad practice has proven to be an efficient, and in some cases, a more effective method of promoting motor learning compared to individual practice. Further, providing individuals control over their own or another learner's practice environment has also been shown to be superior for skill learning relative to individuals without control. The purpose of the experiment was to assess learner-controlled role-switching in dyad practice conditions. In dyads, partners either alternated actor and observer roles on a trial-to-trial basis, or under novel learner-controlled conditions wherein either the actor or the observer was given control over when the partners should switch roles. Participants practiced a speed cup-stacking task and learning was assessed in 24-h retention and transfer tests. Although there were no learning differences between dyad conditions, paired learners effectively chose when to switch roles with their partner, without undermining learning. The results also highlight the dynamic nature of dyad practice as the observers chose to switch roles more frequently than the actors, yet both dyad groups adopted comparable switching strategies by alternating roles following relatively 'good' and 'bad' trials. This experiment provides further support for dyad practice as an efficient and effective method of skill learning.
