The purpose of this study was: (a) to compare individual decision with group decision on reward allocation and (b) to compare pairs of strangers (Exp. I) with pairs of friends (Exp. II). In both experiments, 38 female undergraduates performed tasks in pairs and received a monetary reward for their performances. At first, the subjects individually decided how to allocate the joint reward (individual decision), and afterwards they decided by mutual agreement (group decision). The main measure used was the manner of allocation. Main results were: (a) at the individual decision level, high input subjects used equality allocation and low input subjects used equity allocation in both experiments; and (b) at the group decision level, pairs of strangers (Exp. I) reached an agreement in equity allocation, and pairs of friends (Exp. II) in equality allocation. These results were discussed in terms of the subjects' motivation in the reward allocation situation.
