BEYOND RELATIONAL DEMOGRAPHY: TIME AND THE EFFECTS OF SURFACE- AND DEEP-LEVEL DIVERSITY ON WORK GROUP COHESION.
研究了表层（人口统计）和深层（态度）多样性对工作组社会整合的影响，发现共事时间会削弱表层多样性的作用，同时增强深层多样性的作用。
We examined the impact of surface-level (demographic) and deep-level (attitudinal) diversity on group social integration. As hypothesized, the length of time group members worked together weakened the effects of surface-level diversity and strengthened the effects of deep-level diversity as group members bad the opportunity to engage in meaningful interactions.
