There is a need for robots that can negotiate with people or train people to negotiate with robots. Many previous studies have shown that real-world robots outperform virtual agents. However, despite the fact that human-to-human negotiations take place in the real world, there has been no research on android robots that negotiate. In this study, we compared participants' decision-making in negotiation situations with virtual agents or android robots. Participants (n=82) negotiated with a virtual agent or an android robot as a proposer in a 4-issue multi-issue ultimatum game. The virtual agent or android robot had preferences for each item to be negotiated, and learned the preferences of its negotiation partner by observing the emotional expressions of the partner based on its preferences before the negotiation. As a result, the virtual agents reached a more cooperative solution. Participants tended to perceive androids as creepy and less intelligent, and virtual characters as human-like and intelligent. The requirement for a robot to negotiate better may be personhood rather than existence.
