Audio vs visual

After viewing a Seinfeld episode with visual, auditory and audiovisual product placements, a recall task indicated that audiovisual product placements were recalled the best, visual product placements somewhat less and audio placements least. In a recognition test audiovisual was still remembered the best but audio placements were remembered second best and visual placements were remembered third best. As indicated, the type of placement that is most effective seems to vary depending on task, but audiovisual placements seem to be often the most effective. However, audiovisual product placements are not remembered best when there is more than one audiovisual placement at once, making it hard to remember each one. In case the placement is only on the audio level, advertisers must make sure it is very prominent to have any effect at all.
