|The Path to Glory Is Paved With Hierarchy : When Hierarchical Differentiation Increases Group Effectiveness
|| Richard Ronay, Katharine Greenaway, Eric Anicich, Adam Galinsky
||Two experiments examined the psychological and biological antecedents of hierarchical differentiation and the resultingrnconsequences for productivity and conflict within small groups. In Experiment 1, which used a priming manipulation,rnhierarchically differentiated groups (i.e., groups comprising 1 high-power-primed, 1 low-power-primed, and 1 baselinernindividual) performed better on a procedurally interdependent task than did groups comprising exclusively either all highpower-rnprimed or all low-power-primed individuals. There were no effects of hierarchical differentiation on performancernon a procedurally independent task. Experiment 2 used a biological marker of dominance motivation (prenatal testosteronernexposure as measured by a digit-length ratio) to manipulate hierarchical differentiation. The pattern of results fromrnExperiment 1 was replicated; mixed-testosterone groups achieved greater productivity than did groups comprising all hightestosteronernor all low-testosterone individuals. Furthermore, intragroup conflict mediated the productivity decrements forrnthe high-testosterone but not the low-testosterone groups. This research suggests possible directions for future researchrnand the need to further delineate the conditions and types of hierarchy under which hierarchical differentiation enhancesrnrather than undermines group effectiveness.
