Mediating effect of cognitive load in song learning with visually presented lyrics

Abstract

The purpose of this study was to ascertain whether seeing the lyrics while learning a difficult song aurally induces less cognitive load in learners compared to not seeing the lyrics, leading to better recall accuracy of the learned song. Cognitive load was assessed through a reaction time measure based on a dual-task paradigm. Recall accuracy of the learned song was measured regarding lyrics, pitches, and rhythm. Thirty-six non-music majors individually learned two songs through prerecorded aural instruction; for one song they saw the lyrics and for the other song they did not see the lyrics. The presentation order of instructional condition and song were counterbalanced. Results showed instructional condition affected cognitive load but not recall accuracy. A path analysis revealed a mediating effect of cognitive load regarding lyrics and rhythm, suggesting seeing the lyrics indirectly increases recall accuracy of lyrics and rhythm through its positive effect on cognitive load. Given limited instructional time, several strategies should be considered to prevent learners from experiencing cognitive overload while learning a difficult song aurally. Showing the lyrics of the difficult song could be one strategy for that purpose, at least for young adults with low levels of musical expertise.
