Perceptual biases in chimeric face processing: eye-movement patterns cannot explain it all

Abstract

Experiments using chimeric faces typically report a perceptual bias towards the viewers left. Here we show that this leftward bias can be elicited even when eye movement should be impossible. Although supporting previous studies arguing that eye movements are not necessary to generate the bias, the effect we found here was significantly reduced, compared to an earlier study which allowed eye movements. We suggest that the chimeric face bias is enhanced by eye movements.
