1 Promotion of self-disclosure through listening by robots Takahisa Uchida Hideyuki Takahashi Midori Ban Jiro Shimaya, Yuichiro Yoshikawa Hiroshi Ishiguro JST ERATO Osaka University, JST ERATO Doshosya University Abstract Our research goal was to develop a robot as a listener in counseling situations. It is important to promote self-disclosure of clients to reduce their anxiety feelings. However, when a listener is human, clients sometimes hesitate to disclose intrusive topics due to embarrassment and self-esteem issues. We hypothesized that a robot listener, on account of its unique kind of agency, could remove mental barriers between the listener and the client, and promote in-depth selfdisclosure about negative topics. In this study, we prepared two robots (an android and a desktop robot) as robot listener. First, we confirmed that subjects eagerly self-disclosed to these prepared robots from the numbers of spoken words about self-disclosure in preliminary experiment. And next, we conducted the experiment to verify whether it is possible to expose more of subjects weakness to robots than humans. The experimental result suggested that robots can draw out subjects self-disclosure about negative topics than the human listener. Keywords Self-disclosure, Conversational Robot 1.
