The cheerleader effect arises when subjects rate the attractiveness of faces in groups vs. isolation. The same face stimulus is judged to be slightly more attractive in a group as compared to the isolated display. Several studies have attempted to explain the effect through processing mechanisms of the visual system, such as comparisons, hierarchical encoding, and more. However, empirical results have repeatedly revealed inconsistencies with these explanatory approaches. Previously, we observed initial evidence of the cheerleader effect being modulated by subjects rather than stimuli. Therefore, we reasoned that manipulating the mood should influence the extent of the cheerleader effect. In Experiment 1, we first successfully managed to influence subjects' affect through pleasant and unpleasant odors as revealed by PANAS scores under continous olfactory stimulation via individually benchmarked most-preferred vs. least-preferred fragrances. In Experiment 2, each subject´s cheerleader score was assessed under the two respective odor conditions. As a result, the cheerleader effect appeared under the most-preferred fragrance condition but disappeard under the least-preferred fragrance condition. To the best of our knowledge, this is the first demonstration of intraindividual state differences impacting the cheerleader effect. We speculate that this approach represents a promising avenue for future understanding of this elusive psychophysical phenomenon.
