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

Abstract

This study confirms the presence of a deficit in facial affect recognition, and also of dysfunctional manipulation in configural information in antipsychotic-free patients. Negative symptoms and poor processing of configural information explained a substantial part of the deficient recognition of facial affect. We speculate that this deficit may be caused by several factors, among which independently stand psychopathology and failure in correctly manipulating configural information.

A Qualitative Impairment in Face Perception in Alzheimer’s Disease: Evidence from a Reduced Face Inversion Effect

“…Persons with unmedicated schizophrenia have also been documented to show lower FIE than controls [77], and a reduction of the FIE has also sometimes been reported in neurodevelopmental disorders such as autism, Down syndrome and Williams syndrome [78] although the vast majority of studies investigating the FIE in autism spectrum disorder (ASD) have concluded for a typical effect, despite lower overall performance and general cognitive functioning [79]. To our knowledge, however, no prior study has shown a reduced FIE in Alzheimer's disease.…”

Taking It at “Face Value”: The Use of Face Processing Strategies in Bipolar Disorder and Schizophrenia

“…In patients with SZ, there is evidence that shows that there is a reduction in susceptibility to this facial inversion effect compared to controls (Shin et al, 2008). The implications that this has for emotion processing has been demonstrated recently, in a study indicating that a smaller inversion effect reduces the capacity for accurate identification of emotional expressions in this disorder (Fakra et al, 2015). Given increasing evidence that BD patients have similar, albeit less severe cognitive deficits in emotion recognition as their SZ counterparts (Van Rheenen & Rossell, 2014c), it is possible that the configural processing deficits that have been previously found in SZ extend to BD as well.…”

“…There is a growing literature suggesting that these latter deficits are strongly predictive of the former; with impairments in facial emotion recognition in particular, often cited as a potentially important contributing factor for impaired interpersonal functioning (Brekke, Kay, Lee, & Green, 2005;Kee, Green, Mintz, & Brekke, 2003). In the SZ literature, there have been some attempts to determine the underlying mechanisms associated with these emotion recognition aberrations, with findings pointing toward a potential role for general cognitive ability as well as perceptual face processing per se (Fakra, Jouve, Guillaume, Azorin, & Blin, 2015;Joshua & Rossell, 2009;Kohler, Bilker, Hagendoorn, Gur, & Gur, 2000;Sergi et al, 2007). In the BD literature however, there has been far less attention focused on these lines of enquiry (Van Rheenen, Meyer, & Rossell, 2014).…”

“…This second-order configural processing is an important top-down perceptual skill for distinguishing identities, but also for the appropriate identification of facial expressions that reflect subtle muscular changes in the spatial positioning and relationships between local features (Bombari et al, 2013;Derntl, Seidel, Kainz, & Carbon, 2009;Fakra et al, 2015).…”
