“…Secondly, aberrant social representations such as maladaptive schemas and illusory social agents in psychosis are known to evolve in content and accessibility over the lifespan [108][109]. Although this is not an inherent limitation of a computational social representation models, it has not been substantially tested in psychiatry, as most studies have been restricted to brief lab-based tasks rather than being integrated into longitudinal cohort paradigms where changes in social representations over time can be effectively studied [110].…”

Recent work in social cognition has moved beyond a focus on how people process social reward to examine how healthy people represent other agents and how this is altered in psychiatric disorder. However, formal modelling of social representation has not kept pace with these changes, impeding our understanding of how core aspects of social cognition function, and fail, in psychopathology. We argue that belief-based computational models provide a basis for an integrated sociocognitive approach to psychiatry with the potential to address important but unexamined pathologies of social representation such as maladaptive schemas and illusory social agents.

“…Hallucination is defined in the diagnostic systems as an experience resembling true perception without causal stimulus (Yttri, Urfer-Parnas, & Parnas, 2022). Auditory hallucinations are audible experiences that occur in the absenteeism of an outer stimulus.…”

Background: Auditory hallucinations impact all schizophrenic patients' functioning and their overall quality of life. Self-management categories decrease distress associated with auditory hallucinations. Aim: To explore the effect of an educational program about auditory hallucination self-control on quality of life among schizophrenic patients. Subjects and Method: A quasi-experimental design was used. The subjects comprised 65 hospitalized schizophrenic patients. Setting: The present study was carried out in the inpatient departments of Port-Said Psychiatric and Demira Mental Health Hospitals. Three tools were utilized to collect data which were; phenomenology of auditory hallucinations scale, selfmanagement of auditory hallucinations structured interview schedule, and who quality of life scale, in addition to the personal and clinical data sheet. Results: More than half of the studied patients reported that the total self-management categories were partially successful to control auditory hallucinations pre-program compared to three quarters post-program and more than three quarters follow-up the program implementation. Above three quarters of them had ahigh level of overall quality of life pre and post program, compared to the majority follow-up the program. Conclusion: There was a statistically significant positive correlation between mean scores of physiological categories and quality of life post program.Moreover, there was a statistically significant positive correlation between mean scores of cognitive categories and quality of life erp program. Recommendations: Designing and applying educational programs for schizophrenic patients about adaptive auditory hallucinations self-control categories to develop capacities to control auditory hallucinations effectively and promote quality of life.

“…Despite the increasing frequency and the large number of studies revolving around AVH, their etiology remains debated, with two prominent and seemingly opposing theoretical accounts, suggesting that AVH result either from (1) deficits in self-monitoring, or (2) overly strong perceptual priors. Although both of these carry some empirical support, only theoretical speculations (Leptourgos & Corlett, 2020;Northoff & Qin, 2011;Swiney & Sousa, 2014;Synofzik, Vosgerau, & Newen, 2008;Wilkinson, 2014;Yttri, Urfer-Parnas, & Parnas, 2022) have been made on how they might coexist in the brain and relate phenomenologically.…”

Background Inducing hallucinations under controlled experimental conditions in non-hallucinating individuals represents a novel research avenue oriented toward understanding complex hallucinatory phenomena, avoiding confounds observed in patients. Auditory-verbal hallucinations (AVH) are one of the most common and distressing psychotic symptoms, whose etiology remains largely unknown. Two prominent accounts portray AVH either as a deficit in auditory-verbal self-monitoring, or as a result of overly strong perceptual priors. Methods In order to test both theoretical models and evaluate their potential integration, we developed a robotic procedure able to induce self-monitoring perturbations (consisting of sensorimotor conflicts between poking movements and corresponding tactile feedback) and a perceptual prior associated with otherness sensations (i.e. feeling the presence of a non-existing another person). Results Here, in two independent studies, we show that this robotic procedure led to AVH-like phenomena in healthy individuals, quantified as an increase in false alarm rate in a voice detection task. Robotically-induced AVH-like sensations were further associated with delusional ideation and to both AVH accounts. Specifically, a condition with stronger sensorimotor conflicts induced more AVH-like sensations (self-monitoring), while, in the otherness-related experimental condition, there were more AVH-like sensations when participants were detecting other-voice stimuli, compared to detecting self-voice stimuli (strong-priors). Conclusions By demonstrating an experimental procedure able to induce AVH-like sensations in non-hallucinating individuals, we shed new light on AVH phenomenology, thereby integrating self-monitoring and strong-priors accounts.
