A social Bouba/Kiki effect: A bias for people whose names match their faces.

Abstract

The "bouba/kiki effect" is the robust tendency to associate rounded objects (vs. angular objects) with names that require rounding of the mouth to pronounce, and may reflect synesthesia-like mapping across perceptual modalities. Here we show for the first time a "social" bouba/kiki effect, such that experimental participants associate round names ("Bob," "Lou") with round-faced (vs. angular-faced) individuals. Moreover, consistent with a bias for expectancy-consistent information, we find that participants like targets with "matching" names, both when name-face fit is measured and when it is experimentally manipulated. Finally, we show that such bias could have important practical consequences: An analysis of voting data reveals that Senatorial candidates earn 10% more votes when their names fit their faces very well, versus very poorly. These and similar cross-modal congruencies suggest that social judgment involves not only amodal application of stored information (e.g., stereotypes) to new stimuli, but also integration of perceptual and bodily input.
