La. Peracchio et J. Meyerslevy, HOW AMBIGUOUS CROPPED OBJECTS IN AD PHOTOS CAN AFFECT PRODUCT EVALUATIONS, Journal of consumer research, 21(1), 1994, pp. 190-204
Research in both the consumer and aesthetics literatures suggests that
the ambiguity created by a cropped or incomplete object may prompt pe
ople to seek closure by supplying the missing part. In turn, this proc
ess of resolving the ambiguity can enhance affect. Applying this notio
n to advertisements, a study is reported that examines whether and whe
n severe cropping of key objects in ads will influence people's produc
t evaluations. The results indicate that severe cropping of objects in
ads can enhance product evaluations if people are sufficiently motiva
ted to complete the cropped object and the cropped object does not imp
ede people's attempts to verify the ad claims.
