The Effect of Cultural Heterogeneity, Leader Power, and Leader Attitudes on Group Performance
註釋An experiment was conducted (a) to compare the performance of 96 culturally and linguistically homogeneous and heterogeneous three-man teams under powerful and weak leadership positions and on three types of tasks varying in structure and requirements for verbal interaction, and (b) to test a previously described Contingency Model of Leadership Effectiveness. The experiment, conducted in collaboration with the Belgian Naval Forces, utilized 288 petty officers and men from a naval training center, who were assigned to 96 groups in a 16-cell design. Homocultural and heterocultural groups differed in performance only on the highly verbal task. Heterogeneous groups, despite obvious communication difficulties and culturally divergent background, performed about as well on the structured and non-verbal tasks as did homogeneous groups.
