Perceiving a Mind in a Chatbot: Effect of Mind Perception and Social Cues on Co-presence, Closeness, and Intention to Use

A chatbot equipped with a conversational user interface often allows its users to feel as if they are conversing with a human being. The current study examined whether users' perception of a mind within a chatbot is associated with their feeling of co-presence, closeness, and intention to use and whether the influence of mind perception is reinforced when the chatbot presents social cues in its language. A laboratory experiment (N = 64) revealed that the more participants perceived a mind behind a chatbot, the more co-presence and interpersonal closeness they experienced with the chatbot. The associations with co-presence and closeness became stronger when the chatbot used social cues. Furthermore, mind perception had an indirect effect on intention to use via closeness when social cues were presented. These findings imply the importance of mind perception and social cues in a chatbot's language in creating a positive chatbot experience.
