Objective To probe into the effect of non-contention and different types of contention on team creativity through experiments.Method 64 creative groups composed of 256 primary schoolers completed creative tasks-multipurpose tests under circumstances of non-contention

contention between groups

and contention between and within groups respectively.Scores on three dimensions namely fluency

novelty and appropriacy of groups measured under different levels of contention were compared.Results Differences in scores of fluency under circumstances of non-contention

contention between groups

and contention between and within groups had no statistical significance（F=2.038

p>0.05）;differences in scores of novelty under circumstances of contention between groups and non-contention were statistically significant（F=8.056

p<0.01）

scores under contention between groups were the highest

followed with scores under contention between and within groups and those under the circumstance of non-contention were the lowest;differences in scores of appropriacy under circumstances of contention between groups and non-contention were statistically significant（F=5.439

p<0.01）

scores under the circumstance of non-contention were the highest

followed with scores under contention between and within groups and those under contention between groups were the lowest.Conclusion Different types of contention have significant effects on the team creativity of children.
