“…Reducing nonverbal social perception deficits is considered to be important to improve social and community functioning in schizophrenia ( Walther et al, 2016 ; Pinkham et al, 2017 ). Recently, studies using cognitive social remediation therapy ( Kurtz and Richardson, 2012 ; Muller et al, 2014 ; Mueller and Roder, 2017 ; Bin Kitoko et al, 2020 ; Vita et al, 2021 ), non-invasive brain stimulation ( Mehta et al, 2014 ; Walther et al, 2020a ), as well as, virtual reality ( Rus-Calafell et al, 2014 ; Torregrossa et al, 2018 ; Pavlidou and Walther, 2021 ) all show promising results in alleviating some of the social deficits schizophrenia patients’ experience. This holds true for the reduction of symptom severity and improvement of emotional processing, theory of mind, social functioning, as well as interpretation and use of nonverbal social cues (i.e., gesture performance).…”

BackgroundNonverbal social perception is the ability to interpret the intentions and dispositions of others by evaluating cues such as facial expressions, body movements, and emotional prosody. Nonverbal social perception plays a key role in social cognition and is fundamental for successful social interactions. Patients with schizophrenia have severe impairments in nonverbal social perception leading to social isolation and withdrawal. Collectively, these aforementioned deficits affect patients’ quality of life. Here, we compare nonverbal social perception in patients with schizophrenia and controls and examine how nonverbal social perception relates to daily functioning.MethodsWe compared nonverbal social perception in 41 stable outpatients with schizophrenia and 30 healthy controls using the Mini Profile of Nonverbal Sensitivity (Mini-PONS). The participants evaluated 64 video clips showing a female actor demonstrating various nonverbal social cues. Participants were asked to choose one of two options that best described the observed scenario. We correlated clinical ratings (Positive and Negative Syndrome Scale, Brief Negative Syndrome Scale), Self-report of Negative Symptoms, and functional assessments (functional capacity and functional outcome) with Mini-PONS scores.ResultsPatients performed significantly poorer in the Mini-PONS compared to controls, suggesting deficits in nonverbal social perception. These deficits were not associated with either positive symptoms or negative symptoms (including self-report). However, impaired nonverbal social perception correlated with distinctive domains of BNSS (mainly avolition and blunted affect), as well as functional capacity and functional outcome in patients.ConclusionWe demonstrate that nonverbal social perception is impaired in stable outpatients with schizophrenia. Nonverbal social perception is directly related to specific negative symptom domains, functional capacity and functional outcome. These findings underline the importance of nonverbal social perception for patients’ everyday life and call for novel therapeutic approaches to alleviate nonverbal social perception deficits.

“…Using a similar task, Sergi and Green (2003) and Sergi et al (2006) suggested that social perception in schizophrenia is related to alterations in very early aspects of visual processing, although their results were heavily influenced by the educational status of the experimental subjects. Kitoko et al (2020) report the results of a study using an integrated social perception and knowledge task on people with schizophrenia. Subjects had reduced performance in interpretation and awareness of social conventions.…”

Disturbances in social cognition are a core feature of schizophrenia. While most research in the field has focused on emotion perception, social knowledge, theory of mind, and attribution styles, the domain of social perception has received little specific attention. In this paper, we suggest that this issue can be explained by the lack of a precise and unitary definition of the concept, this leads to the existence of different competing uses of the concept and their conflation with other domains of social cognition. Relying on resources coming from the ecological approach to psychology and the phenomenological tradition in psychiatry, we propose that the concept of Social Perception should be used to refer to low-level pre-reflective processes underlying the awareness of interpersonal interactions with and between others. Clinical data suggests that people with schizophrenia have problems perceiving social situations as opportunities for social engagement, so, in order to fulfil this explanatory need, we propose that the term should be used to capture this important—yet neglected—domain of social cognition. We conclude with the discussion of some future directions for research derived from our proposal.
