Beyond opponent coding of facial identity: Evidence for an additional channel tuned to the average face

Published in:┬áJournal of Experimental Psychology: Human Perception and Performance, Volume 44, Issue 2, 243-260 Abstract “Face identity can be represented in a multidimensional space centered on the average. It has been argued that the average acts as a perceptual norm, with the norm coded implicitly by balanced activation in pairs of channels that respond to opposite extremes of face dimensions (two-channel model). In Experiment 1 we used face identity aftereffects to distinguish this model from a narrow-band multichannel model with no norm. We show that as adaptors become more extreme, aftereffects initially increase sharply and then plateau. Crucially there is… Read More
