Interruptions frequently occur in dyadic human interaction. In addition to serve as turn-taking mechanism, they may lead to different perceptions of both the interruptee and in- terrupter’s interpersonal attitude, engagement and involve- ment. We present an empirical study to investigate whether different interruption types (i.e. amount of overlap between speakers and utterance completeness) and strategies (dis- ruptive vs. cooperative) in agent-agent interaction have an impact on perceived agents’ interpersonal attitude, engage- ment and involvement. We found that the interruption type has more influence on the perceived attitudes of both agents, whereas by using a cooperative strategy (as opposed to a dis- ruptive one) an interrupter is perceived as more engaged and more involved in the interaction.
