“…Twenty-two studies examined sex differences in FEP in adult samples of chronically ill people with schizophrenia. The majority of these studies (n = 19) did not find sex differences in FEP, either on identification tasks [31][32][33][34][35][36][37][38][39][40][41] , discrimination tasks [42,43] , or in studies that included both task types [44][45][46][47][48][49] . Three studies included in Kohler et al [7] , Chan et al [5] , and Savla et al [9] found sex differences in FEP performance on identification tasks in adults with chronic schizophrenia.…”

AIM:To review the literature on sex differences in facial emotion perception (FEP) across the schizophrenia spectrum. METHODS:We conducted a systematic review of empirical articles that were included in five separate meta-analyses of FEP across the schizophrenia spectrum, including meta-analyses that predominantly examined adults with chronic schizophrenia, people with early (onset prior to age 18) or recent-onset (experiencing their first or second psychotic episode or illness duration less than 2 years) schizophrenia, and unaffected first-degree relatives of people with schizophrenia. We also examined articles written in English (from November 2011 through June 2015) that were not included in the aforementioned metaanalyses through a literature search in the PubMed database. All relevant articles were accessed in full text. We examined all studies to determine the sample sizes, diagnostic characteristics, demographic information, methodologies, results, and whether each individual study reported on sex differences. The results from the meta-analyses themselves as well as the individual studies are reported in tables and text. RESULTS:We retrieved 134 articles included in five separate meta-analyses and the PubMed database that examined FEP across the schizophrenia spectrum. Of these articles, 38 examined sex differences in FEP. Thirty of these studies did not find sex differences in FEP in either chronically ill adults with schizophrenia, early-onset or recently diagnosed people with schizophrenia, or first-degree relatives of people with schizophrenia. Of the eight studies that found sex differences in FEP, three found that chronically ill women outperformed men, one study found that girls with early-onset schizophrenia outperformed boys, and two studies found that women (including first-degree relatives, adults with schizophrenia, and the healthy control group) outperformed men on FEP tasks. In total, six of the eight studies that examined sex differences in FEP found that women outperformed men across the SYSTEMATIC REVIEWS Core tip: People with schizophrenia exhibit deficits in facial emotion perception (FEP) compared to healthy controls. These deficits are associated with poorer functioning and more severe symptoms. Although the literature to date suggests that there are few sex differences in FEP in schizophrenia, continued assessment of sex differences in FEP can help researchers and clinicians better understand other sex differences in the disorder and assist in treatment development aimed at improving functioning in people with schizophrenia. This review summarizes and critically evaluates the literature on FEP across the schizophrenia spectrum, focusing on the evidence related to sex differences in FEP.Mote J, Kring AM.

“…In two previous studies (Dougherty et al, 1974;Muzekari & Bates, 1977), the schizophrenic populations had been hospitalized on their current admission more than 5 years. One study (Muzekari & Bates, 1977) suggested that the deficits in schizophrenic recognition of emotion in faces might be due to long-term hospitalization. The schizophrenic subjects in the present study were selected for a much shorter current hospitalization to assess this issue.…”

Typicality range deficit in schizophrenics' recognition of emotion in faces

Severity of thought disorder in schizophrenics was assessed by a task that involved recognition of joy and shame expressions, with the expressions varied for typicality of the emotion category. Accuracy, typicality rating, and reaction time were measured in schizophrenic patients who were high or low on Whitaker's Index of Schizophrenic Thinking (WIST) and in depressive and normal controls. All groups had significant variation of typicality ratings for joy (normal typicality range), but the clinical groups had smaller typicality ranges for shame recognition and higher mean typicality ratings than did normals. High WIST schizophrenics were least accurate on low typical shame expressions. Results imply that, for shame recognition, schizophrenic and depressive groups used common categorization (no typicality variation in category members) rather than resemblance categorization.

“…However, some of these studies also found a specific relationship between affect recognition and positive symptoms such as bizarre behavior (Schneider et al, 1995), thought disorder (Kohler et al, 2000), and overall positive symptoms (Lewis and Garver, 1995). One study reported that combined voice and face affect recognition scores were related to positive and disorganized symptoms but not negative symptoms (Poole et al, 2000), and several groups reported no significant correlations between affect recognition performance and clinical symptoms (Salem et al, 1996;Borod et al, 1993;Muzekari and Bates, 1977;Novic et al, 1984;Wolwer et al, 1996;Addington and Addington, 1998).…”
