Dh. Gruenfeld et Ab. Hollingshead, SOCIOCOGNITION IN WORK GROUPS - THE EVOLUTION OF GROUP INTEGRATIVE COMPLEXITY AND ITS RELATION TO TASK-PERFORMANCE, Small group research, 24(3), 1993, pp. 383-405
The study described in this article examined the integrative complexit
y of shared conceptualizations of group culture: how they can be disti
nguished from member cognitions about group culture and how they affec
t task performance over time. Twenty-two work groups wrote weekly essa
ys about their collective activity over a 12-week period. Group member
s first wrote independent accounts and then collaborated to create a s
ingle group account of their activity during that week. During the fir
st 5 weeks of that period, the integrative complexity of group essays
was not significantly different from that of average individual essays
but was significantly lower than that Of essays written by the highes
t complexity members. During the last 5 weeks, the level of group comp
lexity increased at a greater rate than either the average or highest
individual levels, until it was significantly greater than that of the
average individual and statistically equivalent to that of the highes
t member. The results also supported the notion that the relation of i
ntegrative complexity-at the group level-to the quality of decision ou
tcomes depends on the nature of the task. Taken as a whole, these find
ings support the developing notion that thoughts and ideas can be conc
eived as collective, rather than purely individual, phenomena.
