Voice Processing In Developmental Prosopagnosia

Prosopagnosia is a selective impairment of face recognition, but voice recognition, another function involving the anterior temporal lobe, has rarely been evaluated to confirm that it is modality-specific. Our previous work has shown that acquired prosopagnosic patients with right anterior temporal lesions have intact voice recognition, while bilateral anterior temporal lesions can impair both face and voice recognition. The anatomic basis of the developmental form of prosopagnosia remains uncertain, and the status of voice recognition is also not known.
