Inducing And Maintaining The Intentional Stance By Showing Interactions Between Multiple Agents

In human-computer interaction, it is first necessary for the human to recognize that there is a meaning beyond information provision while interacting with an agent. One of the critical barriers to social human-computer interaction is the mental state of people with respect to agents. Intentional stance is defined to be an appropriate mental stance in human-agent interaction. To induce intentional stance, we showed interactions between multiple agents in this study. The aim of this study is to investigate whether observing interactions between multiple agents can encourage and maintain the intentional stance toward the agents. We conducted experiments in which participants performed a series of tasks to build a house in a virtual world. In this task, two agents helped and interacted with the participants. The participants were divided into two groups; a group that observed the interaction(observation-group) and a group that directly interacted with the agents(direct-group). From the data obtained in the experiment, we investigated whether the participants tried to interact with the agent that analyzed the participant's behavior and questions. As a result, we could confirm that observing the interaction induced the intentional stance, but the effect was weakened in some cases.
