The Benton-Van Allen faces: a lateralized tachistoscopic study.
The Benton-Van Allen Facial Recognition Test (FRT) was adapted to a lateralized same-different task. The lateralized same targets were either physically identical to the central upright faces or had the same face identity but were transformed (3/4-views or shadowed faces). Faces were also modified to include or exclude external features. There was a left hemifield (right hemisphere) advantage only for the most difficult, shadowed faces. The absence of a left hemifield advantage for the matching of upright faces to identical or 3/4-view faces shows bilateral competence for face processing, both by physical and by face identity, and confirms previous observations that the FRT does not discriminate left from right hemisphere-damaged patients. Removal of external features affected performance in the right but not the left visual field, suggesting that the left hemisphere uses a less feature-dependent mechanism than the right hemisphere. This effect was only present in females, who were more lateralized than males.
