> Complex training courses, meditation and cultural exposure were most effective (gs = 0.66), while the use of cognitive manipulation drugs was least and also non-effective, g = 0.10. The type of training material was also important. For instance, figural methods were more effective in enhancing creativity, and enhancing converging thinking was more effective than enhancing divergent thinking.
