Abstract
We compared the contribution of featural information and second-order spatial-relations (spacing between features) in face processing. A fully factorial design had 'features' (eyes, mouth, nose) the same or different across two successive displays, while orthogonally the second-order 'spatial-relations' between those features were the same or different. The range of such changes matched the possibilities within the population of natural face-images. Behaviorally we found that judging whether two successive faces depicted the same person was dominated by features, though second-order spatial-relations also contributed. This influence of spatial-relations correlated, for individual subjects, with their skill at recognition of faces (as famous, or as previously exposed) in separate behavioral tests. Using the same repetition-design in fMRI, we found feature-dependent effects in lateral occipital and right fusiform regions; plus spatial-relation effects in bilateral inferior occipital gyrus and right fusiform that correlated with individual differences in (separately measured) ibehavioral sensitivity to those changes. The results suggest that featural and second-order spatial-relation aspects of faces make distinct contributions to behavioral discrimination and recognition, with features contributing most to face discrimination and spatial-relational aspects correlating best with recognition skills. Distinct neural responses to these aspects were found with fMRI, particularly when individual skills were taken into account for the impact of spatial-relations.
