How Might Robots Change Us? Mechanisms Underlying Health Persuasion in Human-Robot Interaction from A Relationship Perspective: A Position Paper

The application of social robots in persuading people to change health behaviors is an increasing research topic. However, little is known in what ways, and under what conditions, effective health persuasion can be achieved in human-robot interaction (HRI). This position paper presents a conceptual model that integrates interpersonal relationship theories to postulate a mechanism through which social robots can change people’s health behaviors. In this paper, we first briefly describe the two interpersonal relationship theories we selectively focus on, namely social control and interdependence theory, and we discuss the possibility of people forming relationships with social robots. Then, we propose the conceptual model depicting the potential positive and negative influence of social robots’ health persuasion on people’s psychological and behavioral reactions and the modulating role of human-robot relationships. Finally, we discuss the implications of this model for future research.
