Social interaction moderates human-robot trust-reliance relationship and improves stress coping

Abstract

Previous work with non-social human-robot interaction has found no links between trust and reliance [1]. The current study tested the question: Can social interactions moderate trust-reliance relationship? Human-robot interactions may share similar characteristics to social and emotional interactions between humans. We investigated how social and emotional human-robot interactions moderate the trust-reliance relationship and impacts perceived stress coping abilities. In the experimental condition, social and emotional interactions were used to guide the dialogue between a participant and a virtual robot in order to promote team building. In the matched control condition, the interactions were information-focused, without social or emotional interaction. We show that social interaction moderated the effect of trust on reliance such that higher trust led to greater reliance on the robot. The experimental condition also had higher perceived stress coping abilities. These findings contribute to the existing literature and suggest that creating deeper social and emotional interactions with a robot teammate can facilitate human-robot partnership.
