The goal of this study was to examine right hemisphere specialization for faces at the neuronal level. Research has shown that facial recognition relies on the right anterior temporal lobe and involves integrating multiple features (Bukach, Gauthier, & Tarr, 2006). Evidence from rat studies confirms that the anterior temporal lobe is involved in integrating multiple object features (Eacott, Machin, & Gaffan, 2001). However, these studies did not examine differences between the brain's right and left hemispheres.
Patients with category-specific visual agnosia (CSVA) often exhibit a disproportionate
difficulty recognizing objects from biological categories due (in part) to the fact that
exemplars from biological categories tend to be visually and conceptually more similar.
Similarity is often conceived of as a pairwise property (i.e., in terms of distance in a
psychological space matrix), but may be more accurately conceived of as a setwise
property (i.e., in terms of shared features).
The ORE is phenomenon whereby recognition for own race faces is better than
recognition of other race faces. This study examines how non-perceptual factors—social
context, attitudes, and experience—impact the ORE. Participants from three different
racial groups (Caucasian, Black, Asian) completed a face recognition task screening faces
for status-specific targets (baseline, perpetrator, victim), self-report measures of explicit
bias and experience with members from other races and a measure of implicit bias.
Results indicated that non-perceptual factors impact the ORE.
