Investigation of a Human’s Opinion Affected by Social Influence of a Group Norm in a Human-Robot Group After a Human-Robot Scenario

Abstract

In this study, we investigate whether a human-robot scenario continuously had influence on participants after the scenario. Many studies on the social behaviors of robots have been conducted. It is important that these robots try to naturally participate in a human community and behave in a human-like way. As robots get sociable, humans that interact with the robots are likely to be affected by the robots that behave in a human-like manner like they are affected by other humans. In particular, some studies show that robots had influence on humans in some human-robot experimental scenarios. Although several previous studies about social robots investigated the social influence on a human from robots in the human-robot scenario, long-lasting influence on a human after the scenario still incompletely understood. In this study, we investigate the long-lasting effect on human decision-making in an experimental scenario of human-robot groups, which included robots learning group norms. We assess this influence by analyzing the results of two kind of questionnaires that the participants answered during the experimental human-robot scenario and more than one week after the scenario. The questionnaire results reveal that the decision-makings of some participants were limited by a group norm developed in a human-robot group more than one week after the experimental scenario.
