Abstract
Emotional support in the context of psychological caregiving is an important aspect of human–human interaction that can significantly increase well-being. In this study, we tested if non-verbal gestures of a non-humanoid robot can increase emotional support in a human–human interaction. Sixty-four participants were invited in pairs to take turns in disclosing a personal problem and responding in a supportive manner. In the experimental condition, the robotic object performed emphatic gestures, modeled according to the behavior of a trained therapist. In the baseline condition, the robotic object performed up-and-down gestures, without directing attention towards the participants. Findings show that the robot’s empathy-related gestures significantly improved the emotional support quality provided by one participant to another, as indicated by both subjective and objective measures. The non-humanoid robot was perceived as peripheral to the natural human–human interaction and influenced participants’ behavior without interfering. We conclude that non-humanoid gestures of a robotic object can enhance the quality of emotional support in intimate human–human interaction.
