Facial affect recognition and information processing in schizophrenia and bipolar disorder.
This study assessed facial affect recognition and visual attention in a sample of 40 individuals with schizophrenia, at hospitalization and 3 months later during an out-patient phase of relative remission. Secondly, at the out-patient phase the performance of the individuals with schizophrenia on tasks of visual attention, facial affect recognition and facial recognition was compared to the performances of a non-psychiatric control group and a bipolar group on these tasks. Attention was measured with the Continuous Performance Test and the Span of Apprehension task. Facial affect recognition was measured with a discrimination task and an identification task. A measure of facial recognition was also used. The schizophrenia patients performed more poorly on measures of facial affect recognition and facial recognition than both control groups. Despite a significant improvement in symptoms over time, there was no change in facial affect recognition for the schizophrenia subjects. For the schizophrenia subjects there were significant associations between attention tasks and the facial tasks. These results suggest that for individuals with schizophrenia, deficits in facial affect recognition are stable deficits that are related to other impairments in neurocognition. This has implications for psychosocial treatments.
