Abstract
Human judgment and decision making is influenced by artifacts as well as other
people. Human-robot communication in real life has been attracting attention and
robots have begun to be utilized as a human interlocutor in recent years. For instance,
Watanabe et al. (2015) reported that an android as a salesperson could influence human
preferences through a touch display conversation. In order to apply robots as inter-
locutors for human decision making, we need to understand how people are influenced
during interactions with robots. Thus, we investigated how semi-forced choices through
a touch display conversation with an android and human interlocutor influenced human
preferences based on cognitive dissonance theory. The results indicated that people are
more willing to accept a semi-forced choice with an android as an interlocutor rather
than with a human interlocutor.
