Children’s recall of TV ads. Children’s recall and recognition of tele

Children’s recall of TV ads. Children’s recall and recognition of television advertisements was studied in the Journal of Advertising (Spring 2006). Two groups of children were shown a 60-second commercial for Sunkist FunFruit Rock-n-Roll Shapes. One group (the A/V group) was shown the ad with both audio and video; the second group (the video-only group) was shown only the video portion of the commercial. Following the viewing, the children were asked to recall 10 specific items from the ad. The number of items recalled correctly by each child is summarized in the accompanying table. The researchers theorized that children who receive an audiovisual presentation will have the same level of mean recall of ad information as those who receive only the visual aspects of the ad. Video-Only Groupn1=20×1= 3.70s1=1.98A/V Groupn2 = 20×2 = 3.30s2 = 2.13Based on Maher, J. K., Hu, M. Y., and Kolbe, R. H. Children’s recall of television ad elements.
