title: Upright and inverted faces: the right hemisphere knows the difference.
abstract: The existence of a right hemisphere capacity, specific to upright faces was investigated. Upright and inverted faces, equally complex as patterns, were presented under lateralized tachistoscopic conditions to two groups of normal adult subjects. A significant orientation by visual field advantage was found. While there was a highly significant left visual field advantage for upright faces, the visual field difference for inverted faces failed to reach significane. This pattern of results supports the hypothesis that the right hemisphere is specialized for the perception of faces in particular, in addition to its specialization for the perception of visuospatial patterns in general.
