The relative effectiveness of visual and auditory presentations of advertising material was studied by DeWick (1935). A group of 73 college students was divided into two groups. Three presentations of audio and visual advertisements were based on real advertising found in current magazines and on radio. One group heard the advertisement; the other looked at it in the booklet form. The auditory and visual advertisements were different. Time was held constant. After the experiment, the students were asked to write the names of products in order of presentation and then to describe the content. Next, the groups were switched and the same procedure followed. Five months later, all students were given the opportunity to recall the advertisements presented in both media. DeWick reported that: (a) The auditory presentation was superior in the recall of trade names after a delay of from 5 days to 5 months; (b) in immediate recall, both were similar; (c) recall was progressively weaker with visual presentations; (d) recall of ideas expressed in the advertisements was greater with the auditory method than with the visual.
