Social Cognition in Parkinson's Disease after Focused Ultrasound Subthalamotomy: A Controlled Study.

Social cognition (SC) encompasses a set of cognitive functions that enable individuals to understand and respond appropriately to social interactions. Although focused ultrasound subthalamotomy (FUS-STN) effectively treats Parkinson's disease (PD) clinical motor features, its impact and safety on cognitive-behavioral interactions/interpersonal awareness are unknown. This study investigated the effects of unilateral FUS-STN on facial emotion recognition (FER) and affective and cognitive theory of mind (ToM) in PD patients from a randomized sham-controlled trial (NCT03454425). Subjects performed SC evaluation before and 4 months after the procedure while still under blind assessment conditions. The SC assessment included the Karolinska Directed Emotional Faces task for FER, the Reading the Mind in the Eyes (RME) test for affective ToM, and The Theory of Mind Picture Stories Task (ToM PST) (order, questions, and total score) for cognitive ToM. The active treatment group showed anecdotal-to-moderate evidence of no worsening in SC after FUS-STN. Anecdotal evidence for an improvement was recognized in the SC score changes, from baseline to post-treatment, for the active treatment group compared with sham for the RME, ToM PST order, ToM PST total, FER total, and recognition of fear, disgust, and anger. This study provides the first evidence that unilateral FUS-STN does not impair social cognitive abilities, indicating that it can be considered a safe treatment approach for this domain in PD patients. Furthermore, the results suggest FUS-STN may even lead to some improvement in social cognitive outcomes, which should be considered as a preliminary finding requiring further investigation with larger samples sizes. © 2024 International Parkinson and Movement Disorder Society.

Theory of mind in mild cognitive impairment and Parkinson’s disease: The role of memory impairment

BackgroundSocial cognition is impaired in Parkinson’s disease (PD). Whether social cognitive impairment (iSC) is a by-product of the underlying cognitive deficits in PD or a process independent of cognitive status is unknown. To this end, the present study was designed to investigate the weight of specific cognitive deficits in social cognition, considering different mild cognitive impairment subtypes of PD (PD-MCI).MethodsFifty-eight PD patients underwent a neuropsychological battery assessing executive functions, memory, language, and visuospatial domains, together with social cognitive tests focused on theory of mind (ToM). Patients were divided into subgroups according to their clinical cognitive status: amnestic PD-MCI (PD-aMCI, n = 18), non-amnestic PD-MCI (PD-naMCI, n = 16), and cognitively unimpaired (PD-CU, n = 24). Composite scores for cognitive and social domains were computed to perform mediation analyses.ResultsMemory and language impairments mediated the effect of executive functioning in social cognitive deficits in PD patients. Dividing by MCI subgroups, iSC occurred more frequently in PD-aMCI (77.8%) than in PD-naMCI (18.8%) and PD-CU (8.3%). Moreover, PD-aMCI performed worse than PD-CU in all social cognitive measures, whereas PD-naMCI performed worse than PD-CU in only one subtype of the affective and cognitive ToM tests.ConclusionsOur findings suggest that ToM impairment in PD can be explained by memory dysfunction that mediates executive control. ToM downsides in the amnesic forms of PD-MCI may suggest that subtle changes in social cognition could partly explain future transitions into dementia. Hence, the evaluation of social cognition in PD is critical to characterize a possible behavioral marker of cognitive decline.

Impairment of daily occupations in multiple sclerosis: analysis of neuroimaging, general and social cognition, and reserve

BackgroundMultiple Sclerosis (MS) can impact performance of daily occupations in both relapsing-remitting (RRMS) and secondary-progressive (SPMS) clinical courses. Work force participation decreases with advancing physical disability but the influence of non-motor factors, neuroimaging, and reserve have been scarcely investigated. We aimed to evaluate MRI, clinical, and cognitive (social and general) factors associated with impairment in different daily occupations and address whether cognitive and brain reserve have a positive impact on the ability to maintain these activities. MethodsWe prospectively enrolled persons with MS (PwMS) who underwent clinical examination (Expanded Disability Status Scale – EDSS; Timed 25-Foot Walk Test - T25FW; and the Nine Hole Peg Test - 9HPT), general neuropsychological assessment (Brief Repeatable Battery of Neuropsychological Tests – BRBN, including the Symbol Digit Modalities Test - SDMT), social cognition evaluation (Reading the Mind in the Eyes Test), cognitive reserve questionnaire, and MRI (FreeSurfer). We also enrolled healthy subjects for comparison as a control group. Daily occupations (employment, money management, and driving abilities) were assessed in all individuals with questionnaires. ResultsWe included 62 PwMS (32 RRMS and 30 SPMS; mean age 42.8 years; median educational time 12.75 years) and 67 controls (mean age 39.7; median educational time 12.0 years) which were similar regarding demographics, education, and socioeconomic status (p > 0.1). Most PwMS (67.7%) had work-restrictions. They also reported fewer money management and driving abilities than controls (p < 0.001). Work-restriction was associated with physical disability (p = 0.006), SDMT and BRBN performance (p = 0.035 and p = 0.031, respectively), and T2-lesion volume (p = 0.022), with large effect sizes (d > 0.75). After hierarchical linear regression, money management was associated with hand dexterity, general and social cognition, and cognitive reserve (p < 0.03). Variables associated with driving abilities included fatigue, verbal fluency, striatum volume, and brain reserve (p < 0.05). ConclusionsPwMS have more frequent work-restrictions and impairment in money management and driving abilities compared to controls. Cognitive function, physical disability, and MS-lesion burden are strongly associated with work-restriction. Social cognition can also influence financial capacity. Cognitive and brain reserve can help retain some of these daily occupations.

H - 19 "Clinical Validation of a Video- Based Instrument to Assess Social Cognition: INEVICS".

Autism Spectrum Disorder (ADS), are characterized by the lack of social cognition (SC). The evaluation instrument used in this study has the purpose of contributing as an evaluation method directly to the various components of S.C. and demonstrating the possible clinical and discriminatory validity of this audiovisual instrument in the Puerto Rican (P.R.) population with ASD. Exploratory quantitative approach was implemented. This pilot project used 9 videos to assess components of SC, administered virtually. Correction: sum of the results of all the videos, max.81 points. The population selected based on availability: participants with a diagnosis of ASD level one (clinical group) and participants with neurotypical development (control group). Groups were constituted of P.R. males and females between the ages of 8 to 12years. A total of forty-one participated (n = 41). significant difference component: Theory of mind: control group (x-=12.1, SD = 2.84), (x-=14.74, SD = 2.1) clinical group (x-=7.65, SD = 3.07), (x-=10.6, SD = 2.95), t (39) = 4.82 = P < 0.0000 and t (39) = 5.19 = P < 0.0000. Significant difference: S.C.: control group: (x-=56.83, SD = 8.11) clinical group: (x-=40.7, SD = 10), t (39) = 5.68 = P < 0.0000. Discriminant validity video 1: least (0.343) video 3: highest (0.716). Internal consistency: (α= 0.86). INEVICS discriminated against difficulties with S.C. in participants with ASD. The theory of mind component was the most captured. The evaluation of social cognition cannot be dependent on a single social situation but rather requires the identification of the different components in different social situations.

Altered social cognition in early relapsing remitting multiple sclerosis.

People with multiple sclerosis (pwMS) may suffer from some degree of impaired social cognition (SC), the process that integrates the mental operations underlying social interactions. SC is still not clearly characterized in the early stages of MS, and it is not defined whether SC is independent of cognitive impairment. In this cross-sectional study, we aimed to compare SC measures in a population of early (≤5 years) relapsing-remitting MS (RRMS) with an age, sex, and education-matched control group. All participants performed a clinical and a comprehensive neuropsychological assessment. SC evaluation included assessment of facial emotion recognitionn by the Emotion Recognition Task, affective theory of mind (ToM) by the Reading the Mind in the eyes Test (RMET) and cognitive ToM by the Faux Pas test (FPT). Depression, anxiety, fatigue, and quality of life were also assessed. We included 38 pwMS (mean age 34.8 ± 8.7, 78.9% female sex, mean disease duration 1.9±1.3 years) and 38 healthy controls (mean age 34.9 ± 8.4, 81.6% female sex). Altered social cognition was present in 34.2% of pwMS. Participants with MS performed worse than controls on measures of cognitive ToM, and affective ToM. There were no differences regarding FER. Cognitive ToM and FER correlated with cognitive functions, but no correlation was found between affective ToM and cognitive tests. The only clinical factor associated with altered SC was poor quality of life. Social cognition impairment is already present in a significant percentage of early RRMS patients, namely ToM deficits. While cognitive ToM and FER appears to correlate with impaired cognitive results, affective ToM is likely independent of other cognitive functions.

Interdependence theory in humans’ interaction with automated vehicles: The impact of perceived situational factors on trust and cooperation

With the progressive development of automated vehicles (AVs), drivers and AVs need to share driving tasks as the AVs are yet unable to cope with every traffic situation. As these systems continue to evolve, AVs are increasingly perceived as social interaction partners that drivers must trust and with which they must be willing to cooperate. The presented study investigates how drivers’ social evaluation of situational characteristics affects their willingness to cooperate with and exhibit trust toward AVs. The study (n = 82) was conducted online using the random situation design in which participants imagine, describe, and evaluate an interaction with an AV. To evaluate the self-imagined situation, the interdependence theory and its dimensions measured by the Human–Machine-Interaction-Interdependence (HMII) questionnaire (conflict, power, mutual dependence, information certainty, and future interdependence) were used. The results show that 42% of the variance of trust and 35% of the willingness to cooperate could be explained by conflict, information certainty, power, and mutual dependence. Moreover, the findings imply that the interdependence theory can provide a framework needed in driver–vehicle research that can uniformly describe the influence of the social evaluation of the interaction with AVs on trust and willingness to cooperate. The study provides the first evidence that the interdependence theory is a fundamental social cognitive evaluation strategy humans use for interaction with AVs and automated systems in general.

Does culture shape our understanding of others' thoughts and emotions? An investigation across 12 countries.

In this context, we aimed to estimate the influence of participants' nationality on social cognition evaluation. This issue is of particular importance as most cognitive tasks are developed in highly specific contexts, not representative of that encountered by the world's population. Through a large international study across 18 sites, neuropsychologists assessed core aspects of social cognition in 587 participants from 12 countries using traditional and widely used tasks. Age, gender, and education were found to impact measures of mentalizing and emotion recognition. After controlling for these factors, differences between countries accounted for more than 20% of the variance on both measures. Importantly, it was possible to isolate participants' nationality from potential translation issues, which classically constitute a major limitation. Overall, these findings highlight the need for important methodological shifts to better represent social cognition in both fundamental research and clinical practice, especially within emerging international networks and consortia.

Evaluation of social cognition, autistic traits, and dysmorphology in comorbid specific learning disorder and attention-deficit/hyperactivity disorder.

Research on areas such as social cognition, autistic traits, and minor physical anomalies in comorbid Specific Learning Disorder (SLD) and attention-deficit/hyperactivity disorder (ADHD) is limited. In this study, we compared these areas in children aged between 8 and 14 with comorbid SLD and ADHD and their typically developed peers. Emotion recognition and social cognition were evaluated by Faces Test, Reading the Mind in the Eyes Test, Comprehension Test, and Difficulties in Emotion Regulation Scale. Autism Spectrum Screening Questionnaire and Social Responsiveness Scale were used for screening of autism spectrum disorder in children. Furthermore, autistic traits in parents were measured by Autism-Spectrum Quotient. The MPAs of all the subjects were determined by pediatric geneticists. We detected that children with comorbid SLD and ADHD performed worse than controls in all social cognition tests and maternal AQ score had a strong correlation with the Faces Test, DERS, and SRS scores. Also, the total ASSQ score in the comorbid SLD and ADHD group was significantly higher than controls. Finally, MPAs were significantly more frequent in the comorbid SLD and ADHD group. Impairment in social cognition and evaluation of autistic traits and dysmorphology in children with comorbid SLD and ADHD may provide useful information on neurodevelopmental disorders.

Early Intervention in Severe Autism: Positive Outcome Using Exchange and Development Therapy.

Early intervention programs positively affect key behaviors for children with autism spectrum disorder (ASD). However, most of these programs do not target children with severe autistic symptomatology associated with intellectual disability (ID). This study aimed to investigate the psychological and clinical outcomes of children with severe autism and ID enrolled in the Tailored and Inclusive Program for Autism—Tours (TIPA-T). The first step of the TIPA-T is the Exchange and Development Therapy (EDT): an individual neurofunctional intervention consisting of one-to-one exchanges between a child and a therapist taking place in a pared-down environment. It aims to rehabilitate psychophysiological abilities at the roots of social communication through structured sequences of “social play.” Cognitive and socio-emotional skills and general development were evaluated with the Social Cognitive Evaluation Battery scale and the Brunet–Lézine Scale—Revised, respectively, before and after 9 months of intervention in 32 children with ASD and ID. Autistic symptomatology was evaluated with the Behavior Summarized Evaluation—Revised scale at five time-points in a subset of 14 children, both in individual and group settings. Statistically significant post-intervention improvements were found in cognitive and socio-emotional skills. All but one child showed improvements in at least one social domain, and 78% of children gained one level in at least four social domains. Twenty-nine children improved in cognitive domains, with 66% of children improving in at least three cognitive domains. Autistic symptomatology evaluated in one-to-one settings significantly decreased with therapy; this reduction was observed in more than 85% of children. In group settings, autistic symptomatology also decreased in more than 60% of children. Global developmental age significantly increased by 3.8 months. The TIPA-T, including EDT in particular, improves socio-emotional skills of most children with ASD and reduces autistic symptomatology, yet with heterogeneous outcomes profiles, in line with the strong heterogeneity of profiles observed in ASD. At the group level, this study highlights the benefits of the TIPA-T for children with severe autism and associated ID. Assessment of autistic core symptoms showed an improvement of social interaction, both in one-to-one and group evaluations, demonstrating the generalizability of the skills learned during the EDT.

Measuring social cognition in frontotemporal lobar degeneration: a clinical approach.

Alterations in social cognition, a broad term indicating our ability to understand others and adapt our behavior accordingly, have been the focus of growing attention in the past years. Some neurological conditions, such as those belonging to the frontotemporal lobar degeneration (FTLD) spectrum, are associated to varying degrees with social cognition deficits, encompassing problems with theory of mind (ToM), empathy, perception of social stimuli, and social behavior. In this review, we outline a clinical framework for the evaluation of social cognition and discuss its role in the assessment of patients affected by a range of FTLD conditions.

Investigating Developmental Profiles of Children with Autism Spectrum Disorders: Early Indicators and Directions for Intervention

The study describes the relationships between autistic symptomatology severity, developmental heterogeneity, and chronological age for a group of 62 Brazilian children with ASD (59 boys, 3 girls); average chronological age was 42 months and 8 days (SD = 17 months, 15 days). Assessments were carried out with the Social Cognitive Evaluation Battery (SCEB), a French psychological assessment tool currently being validated in Brazil, and the Childhood Autism Rating Scale (CARS). Results indicated a negative correlation between developmental levels and intensity of autistic symptoms; a negative correlation between heterogeneity indices and developmental levels; and a positive correlation between heterogeneity indices and autistic symptomatology intensity. When comparing the group of younger children (less than 33 months) to the older children in the sample, the study demonstrates that early socio-emotional heterogeneity is a developmental marker in young children with ASD, and this finding can lead to personalized intervention programs.

Impact of Executive Functions and Parental Anxiety on the Development of Social Cognition in Premature Children: A Cross-Sectional Case-Control Protocol.

Background: Recent research has identified neuropsychological disorders, specifically executive function disorders, in premature children. Executive functions support goal-oriented mental activity and play a role in the development of social cognition. This underlies the social and emotional behavior of individuals. Parental anxiety is also an important environmental factor that can influence the psycho-emotional development of children.Objectives: The present protocol aims to compare the development of social cognition in school-age children born prematurely to that of school-age children born full-term, and to determine the impact of executive (dys)function and parental anxiety on such development.Methods/Design: In this cross-sectional protocol, 28 prematurely born children aged 7-10 years (“preterm”) and 28 full-term born children aged 7-10 years (“control”) will be included. The “preterm” and “control” groups will be matched for sex and age. The neuropsychological evaluation will include that of non-verbal intellectual efficiency (Raven's colored progressive matrices), verbal level (WISC-IV subtests), and executive functions (NEPSY II subtests and the opposite worlds of TEA-CH). The evaluation of social cognition will be conducted via tests of the theory of cognitive and affective mind. Several dimensions of the level of parental anxiety will be collected through the Spielberg Trait Anxiety Inventory Form Y, Beck Depression Inventory, Social Support Questionnaire-6, Parental Stress Index and, specifically for mothers, the Modified Perinatal Post-Traumatic Stress Disorder Questionnaire.Discussion: The results of this protocol will aid our understanding of the development of social cognition in premature children and to determine the factors that influence such development. This clinical research project, although following a fundamental approach, will have clinical implications because a more precise description of the development of social cognition in this school-age population will make it possible to better determine the cognitive targets of therapeutic actions and to search for predictive indices of the efficacy of practices.Trial Registration:https://clinicaltrials.gov/ct2/show/NCT03007095, identifier: NCT03007095.

When Alterations in Social Cognition Meet Subjective Complaints in Autism Spectrum Disorder: Evaluation With the "ClaCoS" Battery.

Background: Deficit in social communication is a core feature in Autism Spectrum Disorder but remains poorly assessed in classical clinical practice, especially in adult populations. This gap between needs and practice is partly due to a lack of standardized evaluation tools. The multicentric Research group in psychiatry GDR3557 (Institut de Psychiatrie) developed a new battery for social cognitive evaluation named “ClaCoS,” which allows testing the main components of social cognition: Emotion Recognition, Theory of Mind, Attributional Style, and Social Perception and Knowledge. It further provides an assessment of subjective complaints in social cognition.Methods: We compared the social cognition abilities of 45 adults with Autism Spectrum Disorder without intellectual disability and 45 neurotypically developed volunteers using the “ClaCoS” battery, in order to determine its relevance in the evaluation of social cognition impairments in autism. A correlational approach allowed us to test the links between subjective complaints and objectively measured impairments for the different components of social cognition.Results: As expected, the Autism Spectrum Disorder group showed deficits in all four components of social cognition. Moreover, they reported greater subjective complaints than controls regarding their social abilities, correlated to the neuropsychological assessments.Conclusion: The “ClaCoS” battery is an interesting tool allowing to assess social impairments in autism and to specify the altered components, for a better adjustment of tailored social cognition training programs. Our results further suggest that people with Autism Spectrum Disorder have a good social cognitive insight, i.e., awareness into social cognitive functioning, and may thus benefit from social cognitive training tools.

Psychometric Evaluation of Social Cognition and Behavior Measures in Children and Adolescents with Down Syndrome

Individuals with Down syndrome (DS) are often described as socially engaged; however, challenges with social cognition, expressive language, and social interaction are also common in DS and are prospective outcomes of interest for clinical trials. The current study evaluates the psychometric properties of standardized measurements of social cognition and social behavior for potential use as outcome measures for children and adolescents with DS. Seventy-three youth ages 6 to 17 years old (M = 12.67, SD = 3.16) with DS were assessed on social cognition subtests of a neuropsychological assessment at two time points. Caregivers also completed a parent-report measure of social behavior. Measures were evaluated for feasibility, test-retest reliability, practice effects, convergent validity, and associations with broader developmental domains (i.e., age, cognition, and language). All social cognition and behavior measures met criteria for a portion of the psychometric indices evaluated, yet feasibility limitations were identified for the Developmental Neuropsychological Assessment, Second Edition (NEPSY-II) Affect Recognition subtest, and the NEPSY-II Theory of Mind subtest had problematic floor effects for percentile ranks. The Social Responsiveness Scale, Second Edition (SRS-2; T-scores) had high feasibility, moderate to excellent test-retest reliability, and no practice effects, suggesting this measure could be appropriate for use in clinical trials involving youth with DS.

Psychomotor, cognitive, and socio-emotional developmental profiles of children with Rubinstein-Taybi Syndrome and a severe intellectual disability

ABSTRACT Background: Rubinstein-Taybi syndrome (RSTS) is a multiple congenital anomaly syndrome characterised by several typical somatic characteristics and by developmental disabilities with various degrees of severity. Focusing on children with RSTS, the aim of this study was to describe their psychomotor, cognitive, and socio-emotional developmental profiles. Method: Twenty-three children with RSTS (12 boys; 11 girls; mean chronological age: 4 years and 10 months) with severe intellectual disability (mean developmental quotient = 32.39) were recruited from an Expert Department of Medical Genetics. Developmental assessments were carried out with the Brunet-Lézine-Revised scale and the Social Cognitive Evaluation Battery. Results: The participants’ developmental profiles were characterised by heterogeneous psychomotor development, homogeneous cognitive and socio-emotional development, by more severe delays in expressive language, vocal imitation, and symbolic play skills, and by better developmental levels in socio-emotional abilities. Conclusions: Based on these atypical developmental profiles, early interventions should target the three most delayed abilities.

Theory of Mind in multiple system atrophy: comparison with Parkinson's disease and healthy subjects.

Theory of Mind is defined as the ability to attribute mental state and emotions to other people and is relevant to social relationships. The cortical and subcortical regions involved in Theory of Mind are damaged by neurodegenerative processes of Parkinsonian syndromes, so the aim of the present study was to explore, for the first time, possible deficits of Theory of Mind and their cognitive correlates in multiple system atrophy (MSA). Twenty-six patients with MSA, 25 patients with Parkinson's disease (PD) and 25 healthy subjects were enrolled. Cognitive and affective subcomponents of Theory of Mind, executive functions, long-term memory and apathy were evaluated. The three groups did not differ on demographic variables. MSA and PD groups performed worse than healthy subjects on both cognitive (advanced test of ToM) and affective (emotion attribution task) ToM tasks, but no significant difference was found between patients' groups. However, when using another affective ToM task (Eyes Test), MSA group had poorer performance than healthy subjects and Parkinsonian patients, whereas Parkinsonian patients had similar performance to healthy subjects. Regression analysis revealed an association between poor cognitive flexibility and dysfunctional cognitive component of Theory of Mind. Deficit of cognitive and affective components of Theory of Mind occurred in MSA. Dysfunction of cognitive component was related to executive dysfunction (i.e. cognitive rigidity). These findings might suggest the usefulness of an early evaluation of social cognition in MSA to identify individuals with impaired Theory of Mind who are at risk of social withdrawal, and reduced quality of life.

Heterogeneities in Cognitive and Socio-Emotional Development in Children With Autism Spectrum Disorder and Severe Intellectual Disability as a Comorbidity.

Introduction: Intellectual disability (ID) is frequently associated as a comorbidity in autism spectrum disorders (ASD). This study investigated a) how similar the heterogeneity in the cognitive and socio-emotional developmental profiles was for children with ASD and ID, b) the difference between the subjects’ profiles and those of typically developing children (TD) matched for developmental levels, c) the skills existing with the lowest and highest developmental levels, and d) the relationship between developmental profiles in ASD and the severity of autism, ID, and the overall developmental level. Participants: The sample was comprised of 119 children (101 boys and 18 girls) who ranged in chronological age (CA) from 21 months to 14 years (M = 5 years 2 months; SD = 2 years 6 months) with developmental levels lower than 24 months. They came from three countries (France = 40, Brazil = 40, and Algeria = 39). The control group was comprised of 40 TD children from these same countries who ranged in CA from 4 to 24 months (M = 1 year 3 months; SD = 5 months). The ASD diagnosis was carried out according to International Statistical Classification of Diseases and Related Health Problems-10th Edition (ICD-10), Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, Text Revision (DSM-IV-TR), Diagnostic and Statistical Manual of Mental Disorders-5th ed (DSM-5) criteria and the Childhood Autism Rating Scale (CARS). Measures: Children were tested using the Social Cognitive Evaluation Battery (SCEB; Adrien, 2007) by trained psychologists from public and private institutions specialized in the diagnosis of autism and interventions in this field. The SCEB explores 16 functional abilities, in both cognitive and socio-emotional areas, and allows the calculation of domain and area developmental levels and heterogeneity indices for the global, cognitive, and socio-emotional areas. Results: Children with ASD developmental profiles show very high heterogeneity as opposed to TD children. Regardless of the country of origin, there are similarities between the heterogeneous cognitive and socio-emotional developmental profiles of the children with ASD, whose profiles are characterized by lower developmental levels of language and vocal imitation skills, and a relationship between these developmental heterogeneities and the degree of severity of autistic symptomatology, intellectual disability, and overall development level. The implications of this study are presented for clinical assessment and intervention purposes in ASD and ID.

Joint Task Difficulties Estimation and Testees Ranking for Intelligence Evaluation

In this paper, we study the testing tasks evaluation and testees ranking problem, in which tasks have different difficulty levels, and testees have different capabilities.We assume that a testee may have a probability to pass a certain task so as to allow certain uncertainty. The goal of this problem is to simultaneously determine the relative difficulty level of each testing task and the relative capability of every testee, purely based on the test outcome. We design two models to solve this problem. The first one assumes that the test outcome follows a certain Bernoulli distribution; while the second one assumes that the test outcome follows a certain Bernoulli distribution with the beta distribution-type a priori knowledge. Then, we form the original problem into likelihood estimation problems and solve them by using coordinate descent algorithms. We show that the beta distribution-type a priori knowledge is needed, when we only carry out a limited number of tests due to time and financial budgets. All these findings are useful to intelligence tests. Finally, we discuss how to extend this statistical learning model for more general cases as well as in a specific case in the field of Computational Social Systems like artificial social cognition evaluation.

Impairment of the еmotion control and social functioning in psychoses with depressive-paranoid symptoms

Background. The problem of social functioning is one of the most relevant at the present stage. Over the past decades, first being in the sphere of interests of social psychiatry it has become one of the main focuses of research in clinical psychiatry. The number of works on this topic is increasing and motivating researchers to look for predictors of violations in social functioning. Recently, a lot of attention in these studies is devoted to the study of social cognition. Though, the studies are carried out within the framework of individual nosology types. At the same time, in our opinion, it would be interesting to expand the study using the syndromological approach in the "broad field" of psychotic disorders.&#x0D; Aim. Study of social cognition in patients with depressive-paranoid symptoms in psychotic disorders with the following nosology types: paranoid schizophrenia (F 20.0), schizoaffective disorder, depressive type (F25.1) and recurrent depressive disorder, current episode severe with psychotic symptoms of inpatient treatment at the stage of remission.&#x0D; Materials and methods. 61 patients have been examined. They are divided into three groups according to nosology types: 1 group - 21 patients with a diagnosis of paranoid schizophrenia (F 20.0 - Sch), group 2 - 23 patients diagnosed with depressive type of schizoaffective disorder (F 25.1 - SchAD) ) and group 3 - 17 patients suffering from recurrent depressive disorder (F 33.3 - RDD). The evaluation of social cognition, namely the level of emotion management, was conducted using the Russian-language version of the test of J. Meier, P. Selovey and D. Caruso "Emotional Intelligence" (MSCEIT V. 2.0) in the adapted version of E.A. Sergienko, I.I. Vetrova [1] *. One of the four branches of the test was used, namely, "Emotion Management", as well as PANSS and PSP scales.&#x0D; Results. The MSCEIT test emotion control scales are within the normal range, but the ratios are different in three groups: in the group of patients with Sch (and is the highest among the three groups), the indicators of the regulation scale of their own emotional states in relation to the indicators of emotional regulation of the states of other people prevail. The opposite picture is observed in the group of patients with SchAD. At the same time, the group of patients with RDD has low rates on both scales, but they are close to the lower boundary of the norm. Consequently, at each of the nosology types there is a specificity of cognitive impairment caused by the major disease. It is also indicative that the clinical picture of schizophrenia and schizoaffective disorder is similar but opposite in terms of MSCEIT indicators. The revealed link of indicators of the function of managing emotions and the level of social functioning allows us to determine the "targets" for rehabilitation programs in Sch (regulation of emotional states of other people) and RDD (regulation of their own emotional states). However, in this study, no such "targets" have been detected in the SchAD. There has been detected no clear link between the level of social functioning and the severity of the negative (deficient) symptoms, which for a long time has been considered the main factor of social maladaptation, but our data require additional research and more observations.&#x0D; Conclusion. The connection of certain psychopathological symptoms with the indicators of emotional management function allows to determine the "risk groups" among patients with each of the nosology types, which in advance can direct psychotherapeutic or psycho-rehabilitation measures focused on the correction of detected cognitive impairments.
