摘要

We investigated the effects of intragroup and cross-subgroup communications in an experimental field study on demographic faultlines. The results indicated that faultlines explained more variance in perceptions of team learning, psychological safety, satisfaction, and expected performance than single-attribute heterogeneity indexes. In addition, cross-subgroup work communications were effective for groups with weak faultlines but not for groups with strong faultlines. Overall, this study extends the original faultline model, documents the utility of the concept of faultlines, and identifies some of their effects on work group outcomes.
