Effects of Listening Behaviors of a Social Robot on Adult’s Motivation and Performance in Piano Practice

Abstract

The landscape of education with social robots is evolving, especially within the realm of music education. However, past studies have focused on children as music learners and such verbal behaviors as praise. Therefore, it remains unknown whether existing studies are effective for adult learners in musical education as well as how to effectively design the non-verbal behaviors of robots. This study investigates the effective behaviors of social robots by comparing three kinds of listening behaviors: none, nodding (simple listening), and enjoying (affective listening). We developed a music education support system that consists of a social robot and a MIDI keyboard and conducted an experiment with adult participants. Our experimental results described the advantages of affective-listening behavior during music education over simple listening and non-listening based on gender.
