Rapport plays an important role during communication because it can help people understand each others feelings or ideas and leads to a smooth communication. Computational rapport model has been proposed based on theory in previous work. But there lacks solid verification. In this paper, we apply structural equation model (SEM) to the theoretical model on both dyads of friend and stranger. The results indicate some unfavorable paths. Based on the results and more literature, we modify the original model to integrate more nonverbal behaviors, including gaze and smile. Fit indices and other examination show the goodness of our new models, which can give us more insight into rapport management during conversation.
