“…process-specificity for face perception in conjunction with thresholds that produced above chance performance on upright stimuli. One prior study showed an intact face inversion effect in patients, but a face memory paradigm was used and spacing and part processing were not manipulated (Schwartz et al, 2002). Two studies looking at emotion processing showed that both patients and controls had similar inversion effects (Chambon et al, 2006;Schwartz et al, 2002), consistent with the present findings, and again suggestive of relatively intact intrinsic cortical processing.…”

A number of studies show deficits in early-stage visual processing in schizophrenia. Deficits are also seen at more complex levels, such as ability to discriminate faces. This study investigated the "face inversion" effect, which reflects intrinsic cortical processing within the ventral visual stream, as well as contrast sensitivity, which reflects low-level visual processing, in order to evaluate integrity of specific stages of face processing in schizophrenia. Patients with schizophrenia and controls discriminated between pairs of upright or inverted faces or houses that had been manipulated to differ in the shape of the parts or the spatial distance among parts. The duration threshold for above chance performance on upright stimuli was obtained for patients using a house discrimination task. Contrast sensitivity was assessed for gratings of three spatial frequencies ranging from 0.5 to 21 cycles/degree. Patients needed significantly longer time to obtain 70% correct for upright stimuli and showed decreased contrast sensitivity. Increased duration threshold correlated with reduced contrast sensitivity to low (magnocellular-biased) but not medium or high spatial frequency stimuli. Using increased durations, patients showed significant inversion effects that were equivalent to those of controls on the face part and spacing tasks. Like controls, patients did not show inversion effects on the house tasks. These findings show that patients have difficulty integrating visual information as shown by increased duration thresholds. However, when faces were presented at these longer duration thresholds, patients showed the same relative processing ability for upright vs. inverted faces as controls, suggesting preserved intrinsic processing within cortical face processing regions. Similar inversion effects for face part and spacing for both groups suggest that they are using the same holistic face processing mechanism.

“…Still among the studies that found no differences between patients and controls in identity processing, Schwartz, Marvel, Drapalski, Rosse and Deutsch (2002) observed that patients are as influenced as healthy controls by changes in facial configuration This finding supports the idea that schizophrenics have a contextual appraisal of the face, rather than a compartmented one.…”

“…Gur et al (2002) reported no differences between patients and controls in an age estimation task involving emotional faces. Schwartz et al (2002) investigated the effect of configurational changes in emotion recognition and concluded that changes in face position or combination of different faces do not influence the process.

The processing of facial identity and emotion in schizophrenia and its relation with these patients' cognitive and social functioning has been extensively studied over the last 25 years. In this paper, the results of 32 studies indexed in the PubMed database and published between 2001 and 2005 are analyzed and synthesized. Following the description of the problem and presentation of current hypotheses, methodological aspects and findings concerning the processing of facial emotion and identity are discussed. The analysis shows that, despite the growing attention dedicated to the theme and the provision of more specific results, the question of dependence/ independence between the two processes -emotion and identity recognition -and between these and the pervasive cognitive deficits found in schizophrenia remains unanswered.

“…Indeed, Dickey et al (2010) have found that the fusiform gyrus (a part of the brain that is considered critical to configural coding in face recognition, Kanwisher, McDermott, & Chun, 1997) is abnormal in patients with schizophrenia (see also Fakra, Salgado-Pineda, Delaveau, Hariri, & Blin, 2008). Schwartz, Marvel, Drapalski, Rosso, and Deutsch (2002), however, have shown that patients with schizophrenia showed as large a face-inversion effect (an index of configural coding, Edmonds & Lewis, 2007) as non-patients, indicating that configural coding is unaffected in schizophrenia. If schizotypy is related to a reliance on featural coding (coding of information based on the constituent parts independently), we might expect to see changes in paraphernalia to cause deficits in face recognition.…”
