Cartoon embellishments in informative presentations

What effect does the inclusion of cartoon embellishments have on printed and audiovisual presentations? College students read, listened to, or viewed a presentation about the library. Some presentations included cartoons. The results suggest that if comprehension is the only goal, the printed text without cartoons is just as effective as cartoons or audiovisual presentations. If enjoyment is a factor, cartoons or audiovisual presentations should be considered.
