The literature on creativity posits that creative abilities are stable and relatively impervious to short-term interventions. Several studies have, however, reported differential effects of media on children's imaginative play and thinking. The results of these studies are difficult to interpret owing to their reliance on nonstandardized measures of creativity. The present study examines the relative effects of television versus radio on children's creativity. Third and sixth graders were presented a story on television or radio and were then given an adapted version of the “Just Suppose” test of divergent thinking developed by Torrance (1974). Responses were scored in terms of ideational fluency, flexibility, and originality. The results indicated that the two media did not have a differential effect on children's creativity.
