Facial affect recognition in pre-lingually deaf people with schizophrenia

The present study examined facial affect recognition in pre-lingually deaf individuals with schizophrenia. Affective facial-labeling task and the control task of face feature processing (the Benton facial recognition test) were performed by deaf subjects with schizophrenia using French sign language (FSL), hearing subjects with schizophrenia, and hearing healthy controls. Deaf subjects with schizophrenia performed more poorly than hearing clinical controls with schizophrenia or healthy controls on the affective facial-labeling task. No differences were found on the control task between deaf subjects with schizophrenia and hearing clinical or healthy controls. The results showed that facial affect recognition and face feature processing were differently impaired in pre-lingually deaf individuals with schizophrenia, suggesting that neurocognitive backgrounds of impaired affective facial processing may be distinct from those of general impairment in face processing.
