本研究考察了群体组成和信息分布在群体过程和决策中的作用。三人小组完成了一项决策任务，涉及到解决一起谋杀案谜团(Stasser&Stewart，1992)。小组由(A)三个彼此熟悉的人，(B)两个熟悉的人和一个陌生人，或(C)三个陌生人组成。在小组讨论之前，与案件有关的证据要么完全共享(所有成员拥有相同的信息)，要么部分共享(每个成员拥有其他成员无法接触到的几条独特线索)。结果表明，当信息完全共享时，全陌生群体最有可能识别出正确的嫌疑人，而当关键线索仍未被分享时，全熟悉和2个熟悉/1个陌生人群体最有可能识别出正确的嫌疑人。群体过程分析表明，这种结果模式是由于陌生人的“聚合策略”和由熟悉的个体组成的群体的“信息汇集策略”造成的。(C)1996年学术出版社。
This study examines the role of group composition and information distribution on group process and decision making. Three-person groups performed a decision task that involved solving a murder mystery (Stasser & Stewart, 1992). Groups were composed of (a) three individuals familiar to each other, (b) two familiar individuals and a stranger, or (c) three strangers. Prior to group discussion, evidence bearing on the case was either fully shared (all members possessed identical information) or partially shared (each member possessed several unique clues to which no other member had access). The results indicate that all-stranger groups were most likely to identify the correct suspect when information was fully shared, however, all-familiar and 2 familiar/1 stranger groups were most likely to identify the correct suspect when critical clues remained unshared. Group process analysis reveals that this pattern of results was due to an ''aggregation strategy'' on the part of strangers and an ''information pooling strategy'' on the part of groups composed of familiar individuals.
