Face and body perception in schizophrenia: A configural processing deficit?

Increased fusiform area activation in schizophrenia during processing of spatial frequency-degraded faces, as revealed by fMRI

The data suggest that impairments in basic integration abilities may be compensated for by relatively increased activity in the fusiform gyrus in people with schizophrenia, and this region in both degraded conditions.

Relation between facial affect recognition and configural face processing in antipsychotic-free schizophrenia.

This study confirms the presence of a deficit in facial affect recognition, and also of dysfunctional manipulation in configural information in antipsychotic-free patients.

Neurophysiological Correlates of Configural Face Processing in Schizotypy

The findings suggest that neurophysiological deficits in processing facial configurations (N170) are apparent in schizotypy, while the early sensory processing (P100) of faces appears intact, adding to the mounting evidence for analogous neural processing anomalies at the healthy end of the psychosis continuum.

Face perception in schizophrenia: a specific deficit

These results provide compelling evidence for a face-specific deficit in schizophrenia that may be associated with, but separable from, a generalised cognitive impairment.

Are patients with schizophrenia impaired in processing non-emotional features of human faces?

This review aims to disentangle the literature by focusing on the performance of patients with schizophrenia in a range of tasks that required processing of non-emotional features of face stimuli, and exploring whether observed deficits are best considered as “face-specific”.

Processing of facial configuration in individuals at ultra-high risk for schizophrenia

How do schizophrenia patients use visual information to decode facial emotion?

This study provides direct evidence that schizophrenia patients employ an atypical strategy of using visual information to recognize emotional faces, and differs from controls in their use of high-spatial frequency information from eye regions to identify fearful faces.

Dysfunction in Configural Face Processing in Patients With Schizophrenia

The result suggests that the face-recognition deficit in schizophrenic patients is due to specific impairments in configural processing of faces.

The hypothesis that schizophrenic subjects do not benefit as controls do from the use of automatic, top-down processing of deeper level stimuli containing semantic information is supported, but schizophrenics are able to compensate for this deficit by employing a bottom-up strategy requiring longer processing time.

Configural processing in face recognition in schizophrenia

The results suggest that people with schizophrenia rely on configural information to recognise photographs of faces, with a disproportionate effect of inversion on faces relative to other objects.

Deficits in facial-affect recognition and schizophrenia.

Findings about facial-affect recognition in schizophrenia are reviewed and suggestions for future research emphasize careful consideration of affect-recognition deficits in relation to other parameters of schizophrenia.

Perception of Facial Emotion in Schizophrenic and Right Brain-Damaged Patients

Deficits in the perception of facial emotion have been demonstrated in patients with rightsided brain damage (RBD) and schizophrenia (SZ). Furthermore, recent speculations have implicated

Perceptual anomalies in schizophrenia: integrating phenomenology and cognitive neuroscience.

Evidence is presented from phenomenology and cognitive neuroscience that changes in the perceptual field in schizophrenia may represent a core impairment and relationships of deficits in perceptual organization to cognitive and social dysfunction as well as the possible neurobiological mechanisms are discussed.

Interpersonal problem solving and information processing in schizophrenia.

Significant and robust relationships were found between sensitivity to social cues and receiving, processing, and sending skills and Associations between problem solving and cognitive deficits did not seem to be attributable to psychiatric symptoms.

The Face-Inversion Effect as a Deficit in the Encoding of Configural Information: Direct Evidence

It is suggested that an ‘encoding bottleneck’ for configural information may be responsible for the face-inversion effect in particular, and memory for faces in general.

Is emotion processing a predictor of functional outcome in schizophrenia?

Examination of relationships between perception of emotion and aspects of psychosocial functioning in 94 clinically stabilized schizophrenia outpatients from five community-based rehabilitation programs suggests that emotion processing is a key determinant of work functioning/independent living for individuals with serious mental illness.
