Estimating Cohesion in Small Groups using Audio-Visual Nonverbal Behavior

Cohesiveness in teams is an essential part of ensuring the smooth running of task-oriented groups. Research in social psychology and management has shown that good cohesion in groups can be correlated with team effectiveness or productivity so automatically estimating group cohesion for team training can be a useful tool. This paper addresses the problem of analyzing group behavior within the context of cohesion. 4 hours of audio-visual group meeting data was used for collecting annotations on the cohesiveness of 4-participant teams. We propose a series of audio and video features, which are inspired by findings in the social sciences literature. Our study is validated on as set of 61 2-minute meeting segments which showed high agreement amongst human annotators who were asked to identify meetings which have high or low cohesion.
