Asymmetries in face processing: Evidence for a right hemisphere perceptual advantage

Investigation of lateral performance asymmetries in the early stages of face processing was conducted using a task which avoided the need either to memorise or to compare two faces. Subjects were merely required to decide whether or not a laterally presented stimulus constituted a face. Analysis of the latencies indicated a LVF advantage for this task which is interpreted, in conjunction with the evidence from patients suffering from prosopagnosia, as indicating a right hemisphere superiority in synthesizing facial percepts.
