Lateralized costs of divided attention to faces.

ABSTRACT: We used a dual-task paradigm to study the relationship between lateralized face perception and attention by measuring the costs of dividing attention between faces viewed in opposite visual fields. Observers performed judgments of either the sex, orientation, or color of one (single-task, cued) or both (dual-task, uncued) faces in a tachistoscopically viewed pair. We observed dual-task costs (i.e., decreased accuracy for dual- relative to single-task performance) for categorical judgments of face sex (female/male) and orientation (upright/inverted), both of which necessitated visual processing of face-specific information. We did not observe costs for judgments of face color (red-tinted/greyscale), which could be performed without processing face-specific visual information per se. We also
