It is thought that, in conversation, we generally act and judge whether participants’ conversational behaviors are appropri-ate at that time; that is, we avoid interruption of talk in formal situations. However, which behaviors are appropriate inwhat kinds of situations has been not studied well. Therefore, in this study, we focus on the violation of turn-taking rules(i.e., overlap or interruption) and investigate which behaviors are appropriate in each situation through an experiment usinginteractive robots/agents that can regulate conversational behaviors. The results showed that violation in formal situationssignificantly lowered the sense of unity, but, on the other hand, the sense of unity in informal situations showed no signif-icant difference between contexts of violation and obeying of rules. Thus, the violation of conversational behaviors in aninformal situation may maintain a sense of unity and this may contribute to revealing the mechanism behind perception ofconversational behaviors.
