A six-month longitudinal study (N = 33) proved the influence of a diversified sport enrichment program on the development of creative thinking in team ball sports among gifted children. A contrast between a gifted control group and a non-gifted treatment group showed that the creative performance of the gifted children significantly improved (partial eta-squared = 0.26). To explain this surprising short-term effect, a second experiment chose the Inattentional Blindness paradigm to study the individual differences in the visual attention of gifted (n = 54) and nongifted children (n = 58). The results of the monitor-task by Most et al. (2000) revealed significant differences between both samples in the "Near" condition (delta = 0.37) but not in the "Very far" condition. The results of both experiments are discussed in connection with further research. (Contains 4 figures and 1 note.)
