Is What You See, What You Get?
研究了57个银行分支团队，发现表面异质性（性别、种族）和深层异质性（集体主义价值观、任期）对团队内部效能和外部声誉有不同影响，其中任期异质性降低效能，性别和集体主义异质性提升声誉。
In this study, the authors observed and examined 57 bank branch teams to better understand the consequences of two types of team heterogeneity— surface level (gender and ethnicity) and deep level (collectivism cultural values and tenure)—on internal (group efficacy) and external (team reputation) team outcomes, arguing in general that heterogeneity has a negative impact on group efficacy but a positive impact on team reputation. As proposed, teams with lower tenure heterogeneity had higher group efficacy, and teams with higher gender heterogeneity and higher collectivism heterogeneity received better ratings on team reputation. However, contrary to the hypotheses, the relationship between collectivism heterogeneity and group efficacy was positive, and the relationship between ethnic heterogeneity and team reputation was negative. Implications for theories of social cognition, group development, and international management are discussed.
