Participation in Heterogeneous and Homogeneous Groups: A Theoretical Integration

This article presents a theoretical formulation that integrates, within the framework of expectation states theory, theories of the emergence of power-and-prestige orders in status-heterogeneous and homogeneous task-oriented groups. A model based on this theoretical formulation is construted and used for predicting participation rates in open interaction settings. The article explores the fit of the moel to data from both status-heterogeneous and status-homogeneous groups.
