When ads are particularly creative or original, how do viewers respond? Radish et.al.(2003) compared viewing behavior,affective responses, and memory for “implicit” and “explicit” ads. The explicit ads featured text and images that were related to one another and to the product being advertised in a fairly straight forward manner while, in the implicit ads , these relationships were more creative and less direct. The implicit ads were viewed for longer than their explicit counterparts and, while mean fixation duration and saccade amplitude did not differ across ad types, the implicit ads received significantly more fixation than did the explicit ads. Subject also liked the implicit ads better than the explicit ones and rated them to be more interesting than their explicit counterparts. Overall, memory for the implicit and explicit ads was similar , but a detailed analysis suggested that there might have been a slight advantage for the implicit ads in some condition (see also Pieters et al.,1999b).
