The expression of affect and the performance of decision-making groups

Abstract

Examined how the timing of the expression of affect influences the performance of decision-making groups. 196 undergraduates were instructed either (1) to express affect at the outset of a meeting and again later if needed, (2) to delay affect expression until after alternative solutions were generated, (3) to avoid affect expression, or (4) were given no instructions regarding affect expression. Results show that the highest quality decisions and most diverse alternatives were produced by groups that delayed affect expression. These groups were also seen by members to be more effective, energetic, able to consider a wider range of alternatives and ideas, and less likely to evaluate their progress than others. Results indicate 2 dysfunctional consequences of the early expression of affect: a reduction in group energy and a narrowing of the range of accepted ideas. Failure of certain groups to carry out an experimental manipulation requiring them to avoid completely the discussion of affect in their decision making is discussed.
