Abstract
This study examines the effects of educational specialty and nationality faultline strength on the team processes of task-relevant information sharing and social interactions and subsequent team performance using data from 308 individuals working in 50 student project teams. We found that educational specialty faultline strength negatively predicted task-relevant information sharing, and that nationality faultline strength negatively predicted off-task social interactions. Furthermore, task-relevant information sharing enhanced team performance and heightened identity salience. The theoretical and practical implications of our findings are discussed.
