Abstract
Numerous studies report a negative event-related potential at occipito-temporal scalp sites between 130 and 200 ms (N170) that is larger when elicited by faces than by other object categories. Thierry and colleagues argued that this effect reflects an artifact of uncontrolled interstimulus perceptual (physical) variance (ISPV), which when controlled eliminates the difference between faces and nonfaces.
