The purpose of this study is to verify the creativity of an individual and a group level, and the effect of rewards in a group level.
With the purpose of the study, two hypotheses established and verified are as follows :
In testing Hypothesis 1, group members were classified into a non-interaction group (individual level) and an interaction group (group level), and then creative ideas of the groups were analyzed with a view to comparing the creativity of an individual level and that of a group level. The subject groups being randomly consisted of 4∼6 persons were 16 teams of an individual level, and 27 teams of a group level. The testing result was that the scores of creative ideas of an interaction group (group level) were significantly higher than a non-interaction group (individual level), which was t=2.129, p<.05.
In testing Hypothesis 2, subjects groups were divided into a group of promised to group rewards and a group of non-promised to group rewards, and then creative ideas of the groups were analyzed with intent to verify the effect of rewards on each group. The subject groups were analyzed as divided into 13 teams of promised to group rewards and 14 teams of non-promised to group rewards. The testing result was that a group of promised to group rewards produced creative ideas significantly more than a group of non-promised to team rewards, which was t=3.713, p<.01.
