This perceptual organization (PO) impairment has not been found in other psychiatric disorders. However, recent data on body dysmorphic disorder (BDD), suggest that BDD may also be characterized by reduced PO. Similarities between these groups could have implications for understanding the RDoC dimension of visual perception in psychopathology, and for modeling symptom formation across these two conditions. We compared patients with SCZ (n=24) to those with BDD (n=20), as well as control groups of obsessive-compulsive disorder (OCD) patients (n=20) and healthy controls (n=20), on two measures of PO that have been reliably associated with schizophrenia-related performance impairment. On both the contour integration and Ebbinghaus illusion tests, only the SCZ group demonstrated abnormal performance relative to controls; the BDD group performed similarly to the OCD and CON groups. In addition, on both tasks, the SCZ group performed more abnormally than the BDD group. Overall, these data suggest that PO reductions observed in SCZ are not present in BDD. Visual processing impairments in BDD may arise instead from other perceptual disturbances or attentional biases related to emotional factors.</dcterms:abstract> <dc:creator>Keane, Brian P.</dc:creator> <dc:creator>Feusner, Jamie D.</dc:creator> <dc:creator>Mikkilineni, Deepthi</dc:creator> <dc:contributor>Elliott, Corinna M.</dc:contributor> <dc:contributor>Mikkilineni, Deepthi</dc:contributor> <dc:rights>terms-of-use</dc:rights> </rdf:Description> </rdf:RDF>
