Abstract:
Two experiments tested the "bigger is better" (BIB) effect, whereby bigger objects are perceived more favorably than smaller ones. In Experiment 1, participants directly compared pairs of objects and a strong BIB effect was obtained for both positively and negatively valenced stimuli. In Experiment 2, comparative and absolute evaluations were combined in a single experiment and the BIB effect was mediated for positively and negatively valenced stimuli. Taken in combination, the data support a complex hypothesis that pair-wise presentations induce a comparative process that causes a BIB effect. But when objects are evaluated separately, size and valence interact such that increased size evokes more positive ratings of positive objects and more negative ratings for negative objects.
