Enhancing creativity Do external rewardsโ€”things like money, praise, fame, and grades โ€”promote creativity? Researcher Teresa Amabile recruited 47 experienced creative writers who were college students and divided them at random into two groups. The students in one group were given a list of statements about external reasons (E) for writing, such as public recognition, making money, or pleasing their parents. Students in the other group were given a list of statements about internal reasons (I) for writing, such as expressing yourself and enjoying wordplay. Both groups were then instructed to write a poem about laughter. Each studentโ€™s poem was rated separately by 12 different poets using a creativity scale. 26 These ratings were averaged to obtain an overall creativity score for each poem. Parallel dotplots of the two groupsโ€™ creativity scores are shown here.
