The prevailing explanation for the experimental finding that radio stores elicit more novel responses than do television stories is that viewers have difficulty dissociating themselves form ready-made television images (visualization hypothesis). In this experiment, we investigated a rival hypothesis that radio stories elicit more novel responses than do television stories because they are less well remembered (faulty-memory hypothesis). We presented 64 children at two age levels (grades 1 to 2 and 3 to 4) with one radio story and one television story, and exposed half the children in both age groups to the radio story twice to stimulate their memory. Contrary to the faulty-memory hypothesis, double presentation of a radio story did not result in fewer novel ideas than did a single presentation. In the older age group, radio stories elicited more novel responses than did television stories. We found no medium difference in the younger age group.
