The impact of an anthropomorphic robot’s facial expressions on L2 learning outcomes and motivation

Abstract: In a regular classroom setting, a more emotionally expressive teacher has been shown to be positively correlated with learning outcomes and task motivation among the students. Would this also be the case if the teacher were a robot? This study investigates how the facial expressions of an anthropomorphic robot affect learning outcomes and task motivation in adult learners studying a second language by setting up an experiment using the Furhat robot. The same interactions were carried out by an experiment group and a control group. The results show no increase in performance in either learning outcomes or task performance. Future studies are suggested to investigate other potential factors of why robots outperform regular computers in these settings.
