 Abstract: It has long been argued that face and word perception rely on highly specialised and more or less independent cognitive processes. Evidence from single case studies of patients with alexia and prosopagnosia has strongly contributed to this view. Most case studies carried out in cognitive neuropsychology select patients according to their primary symptoms and conduct an in-depth investigating of the function of interest. In the current study, we have taken the opposite approach and selected patients on the basis of anatomical criteria. We investigated how the visual perception of faces and words are affected by posterior stroke restricted to either the left or to the right hemisphere. Four patients were included in the study, and all patients were tested with sensitive tests of face and word perception. All patients showing deficits in the visual recognition of one of the two categories investigated, also showed deficits in the visual perception of the other category. One patient performed within the normal range on all tasks. Our results suggest that these abnormal performances do not represent general visual perceptual deficits but are specific to the visual categories investigated. These observations lead us to the conclusion that both hemispheres contribute to the visual perception of faces and words and that they might do so to different degrees. We argue that these cognitive neuropsychological findings are consistent with growing evidence that face and word recognition might be more associated than first thought. In the current study, we have shown that investigating a group of patients selected on the basis of anatomical criteria (lesion-localisation) rather than on the basis of symptom profiles can lead to novel findings.
