The assumption that the quality of group decisions depends on satisfyi
ng certain requisite communication functions underpins much research o
n small groups. Paradoxically, even when groups are knowledgeable abou
t required functions, interactional and situational constraints can in
terfere with their use. This study tested whether imposing a reminder
function into the group ensures a decision process that optimizes grou
p effectiveness. Results indicate that groups trained in decision proc
esses produce higher quality decisions than do untrained groups but th
at trained groups with nonleader reminders produce significantly highe
r quality decisions than do either trained or untrained groups.
