Are you angry? Neural basis of impaired facial expression recognition in pre-manifest Huntington's

IntroductionEarly non-motor symptoms in Huntington's disease (HD), including visual perceptual difficulties, can have profound negative impacts on quality of life. In particular, deficits in emotion recognition may contribute to misinterpretation of social cues, and may adversely affect interpersonal relationships, work relationships and/or general well-being. This may be particularly salient during the pre-manifest period, a period prior to the onset of motor symptoms. We sought to evaluate impairments in emotion recognition in gene-positive individuals who did not meet criterial for a diagnosis of HD; we also sought to determine associations between emotion recognition processing and altered cortico-striatal circuitry. MethodsWe used a standardized battery to evaluate performance on a facial expression recognition task in a cohort of motor pre-manifest HD (Pre-HD) individuals (N = 21). Functional MRI (fMRI) was then used to assess the face processing network in a subset (N = 15). ResultsWe found significantly decreased response accuracy to certain facial expressions, particularly of negative emotions (p < 0.001) in Pre-HDs. When Pre-HDs viewed faces with different emotions, activation within the Superior Temporal Sulcus (fSTS) was reduced compared to controls; in contrast, the level of evoked response within other face-selective cortical regions was comparable. ConclusionEarly deficits in emotion recognition in Pre-HD appear to be associated with alterations in the fSTS response, a distinctly different pathway from that involved in face perception and provide support for early cognitive and behavioral interventions.

Неперевод как палимпсест в непрозрачной поэзии

Ezra Pound’s “Pisan Cantos” is a multi-layered palimpsest rewritten and written over previous editions several times, in which the non-translation of quotes, sayings and headlines becomes an aesthetically significant device. Younger branches of complex poetry after 1945, on the one hand, overcome Pound’s total project, on the other, inherit him through this ‘gap’. Within the framework of this article, the author explores how hermetic poetry (language writing, metarealism and generation of the 21st century) uses non-translation and untrans­latable to create/express political and ontological problems corresponding to this gap. So, in “Drafts” by Rachel Blau DuPlessis, palimpsest exposes the very deployment of language, writing, the ‘trace’ of other languages — all this develops together with the optics of studying writing and the loosening of the dominant hierarchies of poetic subjectivity and artistic form. In the poetry of metarealists Arkady Dragomoshchenko and Alexei Parshchikov, non-translation serves as a way of creating palimpsest marginalia, structuring the perception of interweaving images both through donor text and through the transformation of its motives. And the discommunicative palimpsest of Ekaterina Zakharkiv’s poem “Hiroo Onoda” is based on the unrepresentative function of the non-translation, when the collision of different lan­guages, quotes and references creates both difficulty in perception and communicative faults in the narrative fabric of the work. Thus, the article is an attempt to derive points on a con­tour map of poetic practices, showing both the formation of a way of inter-linguistic inte­rac­tion within the text that is different from multilingualism, and the ways of inheritance through the rupture of the complex and ambiguous nature of Ezra Pound’s “Cantos”, which gave rise not only to a new type of modernist epic, but also a special type of poetic palimpsest.

Perfil linguístico de crianças com transtornos de linguagem e fala e participação da família no processo terapêutico: revisão integrativa de literatura

ABSTRACT Purpose: to investigate the linguistic profile (linguistic symptoms and risk factors) of children with communication, language, and speech disorders and verify their family’s participation in the therapeutic process. Methods: an integrative literature review including studies on linguistic symptoms of children with developmental language disorder (DLD), autism spectrum disorder (ASD), and phonological disorders (PD), published in Portuguese in the last 10 years (2012 to 2022) in the PubMed, SciELO, and VHL databases. Literature Review: 24 studies were included, according to the eligibility criteria, the children having different linguistic symptoms. In PD, there were more phonological processes, slower speech, and difficulties in auditory perception and morphosyntactic and semantic development. In DLD, there were changes in nominal morphology, morphosyntactic comprehension, greater use of intransitive verbs, omission of verb objects, and difficulties in solving conflicts. In ASD, there were difficulties in social interaction, imitation, prosodic changes, and decreased responsiveness. The main risk factor was prematurity, and the family was considered crucial as a support network in the therapeutic process. The family’s attitudes were facilitators or barriers to the patients’ improvement, depending on how they responded to the therapists’ instructions. Conclusion: the linguistic profile depends on the various language/speech disorders. Each child’s singularities must be considered, and the family’s participation is crucial to the therapeutic process.

Early Detection of Diabetic Retinopathy Using Various Techniques: A Review

Diabetic retinopathy is a complication of diabetes, caused by high blood sugar levels damaging the back of the eye (retina). It can cause blindness if left undiagnosed and untreated. However, it usually takes several years for diabetic retinopathy to reach a stage where it could threaten your sight. Diabetic retinopathy is caused by damage to the blood vessels in the tissue at the back of the eye (retina). Poorly controlled blood sugar is a risk factor. Early symptoms include floaters, blurriness, dark areas of vision and difficulty perceiving colors. Blindness can occur. Mild cases may be treated with careful diabetes management. Advanced cases may require laser treatment or surgery. DR is characterized by lesions on the retina and this paper focuses on detecting two of these lesions, Microaneurysms and Haemorrhages, which are also known as red lesions. Microaneurysms are usually the earliest visible manifestation of diabetic retinopathy. They appear as tiny red dots scattered in the retina posteriorly. They may be surrounded by a ring of yellow lipid, or hard, exudates or diabetic retinopathy that is threatening or affecting your sight, the main treatments are: Laser Treatment – to treat the growth of new blood vessels at the back of the eye (retina) in cases of proliferative diabetic retinopathy.

Unraveling Spatial-Spectral Dynamics of Speech Categorization Speed Using Convolutional Neural Networks.

The process of categorizing sounds into distinct phonetic categories is known as categorical perception (CP). Response times (RTs) provide a measure of perceptual difficulty during labeling decisions (i.e., categorization). The RT is quasi-stochastic in nature due to individuality and variations in perceptual tasks. To identify the source of RT variation in CP, we have built models to decode the brain regions and frequency bands driving fast, medium and slow response decision speeds. In particular, we implemented a parameter optimized convolutional neural network (CNN) to classify listeners' behavioral RTs from their neural EEG data. We adopted visual interpretation of model response using Guided-GradCAM to identify spatial-spectral correlates of RT. Our framework includes (but is not limited to): (i) a data augmentation technique designed to reduce noise and control the overall variance of EEG dataset; (ii) bandpower topomaps to learn the spatial-spectral representation using CNN; (iii) large-scale Bayesian hyper-parameter optimization to find best performing CNN model; (iv) ANOVA and posthoc analysis on Guided-GradCAM activation values to measure the effect of neural regions and frequency bands on behavioral responses. Using this framework, we observe that α-β (10-20 Hz) activity over left frontal, right prefrontal/frontal, and right cerebellar regions are correlated with RT variation. Our results indicate that attention, template matching, temporal prediction of acoustics, motor control, and decision uncertainty are the most probable factors in RT variation.

Diurnal effects of dynamic lighting on alertness, cognition, and mood of mentally fatigued individuals in a daylight deprived environment

This study investigated the non-image forming (NIF) effects of dynamic light on alertness, cognitive performance and mood on mental fatigue, as well as moderation of task difficulty in lighting perception. Sixteen participants completed a psychomotor vigilance test (PVT) and two complex cognitive tasks (multi-attribute task battery-II (MATB-II) and n-back) with low, medium and high difficulty levels under dynamic (4000 to 12 000 K, melanopic equivalent daylight illuminance (EDI) = 224 lx to 420 lx) and static (4000 K, melanopic EDI = 224 lx) lighting with illuminance set at 500 lx on the desk. Psychological, behavioural, biochemical and electrophysiological responses to light were assessed. The results showed that exposure to dynamic light had significant benefits on subjective sleepiness, positive mood and task performance, which may be moderated by task difficulty. The intervention effect of dynamic light on fatigue was also found during an electrophysiological activity due to increase in the amount of attentional resources allocated to the tasks by dynamic light, but was not observed in biochemical measures.

Responses in left inferior frontal gyrus are altered for speech-in-noise processing, but not for clear speech in autism.

Autistic individuals often have difficulties with recognizing what another person is saying in noisy conditions such as in a crowded classroom or a restaurant. The underlying neural mechanisms of this speech perception difficulty are unclear. In typically developed individuals, three cerebral cortex regions are particularly related to speech-in-noise perception: the left inferior frontal gyrus (IFG), the right insula, and the left inferior parietal lobule (IPL). Here, we tested whether responses in these cerebral cortex regions are altered in speech-in-noise perception in autism. Seventeen autistic adults and 17 typically developed controls (matched pairwise on age, sex, and IQ) performed an auditory-only speech recognition task during functional magnetic resonance imaging (fMRI). Speech was presented either with noise (noise condition) or without noise (no noise condition, i.e., clear speech). In the left IFG, blood-oxygenation-level-dependent (BOLD) responses were higher in the control compared to the autism group for recognizing speech-in-noise compared to clear speech. For this contrast, both groups had similar response magnitudes in the right insula and left IPL. Additionally, we replicated previous findings that BOLD responses in speech-related and auditory brain regions (including bilateral superior temporal sulcus and Heschl's gyrus) for clear speech were similar in both groups and that voice identity recognition was impaired for clear and noisy speech in autism. Our findings show that in autism, the processing of speech is particularly reduced under noisy conditions in the left IFG-a dysfunction that might be important in explaining restricted speech comprehension in noisy environments.

Effective of Hippotherapy and Balance-Based Torso-Weighting to Improve Standing Stability and Postural Balance in Children with Down Syndrome

Down syndrome is a genetic disorder caused by an extra abnormal presence of the 21st chromosome. Some abilities related to motor function are extensive, for example, lack of postural control, gait abnormality, and lack of balance and coordination. In addition, postural changes in Down syndrome may occur due to the difficulty of perception of responses, which impairs the feeling of the limb position and limb movements. Hippotherapy (HT) is a physical treatment, and it is defined as equine-assisted treatment in which horse movement promotes physical and physiological improvements. Strategic placement of lightweight on the torso using the balance-based torso-weighting (BBTW) method has improved stability and reduced falls in people with cerebellar ataxia but has not been tested in Down syndrome. Therefore, we examined whether torso-weighting increased standing stability and or functional movement in children with DS. A total of 30 subjects with Down syndrome were taken and grouped into two groups, with group A- 15 subjects treated with hippotherapy and group B-15 subjects treated with balanced-based torso-weighting. The baseline measurement was taken using Berg's balance scale and the time up and test (TUG test). Statistical package for social science (SPSS) version 24. The paired t-test was to find the statistical difference within the groups &amp; Independent t-test (Student t- Test) was adopted to see the statistical difference between the groups. The procedure is done by performing hippotherapy for 4 times a week for 12 weeks for group A, and balanced-based torso weighting is performed for 4 times a week for 12 weeks for group B. Children medically diagnosed with DS and with IQ less than 50 were excluded from the study. In this study, hippo therapy with conventional treadmill training gives a better improvement in a patient with down syndrome when compared with balance-based torso weighting with conventional treadmill training. Hence, hippo therapy with conventional treadmill training would be the better treatment for down syndrome.

Motor Skills and Visual Deficits in Developmental Coordination Disorder: A Narrative Review.

Developmental coordination disorder (DCD) is a developmental disorder in which numerous comorbidities seem to coexist, such as motor and visual impairment and some executive functions; Methods: A narrative review on motor and visual deficits in children with DCD was carried out; Results and Discussion: Fine and gross motor skills are affected in children with DCD. In addition, they seem to be related to visual deficits, such as difficulty in visual perception, sensory processing and visual memory. Limitations have also been found in accommodation. Interventions in children with DCD should be aimed at improving both aspects, since vision affects motor skills and vice versa; Conclusions: In children with DCD, who present a marked deficit in global shape processing, it causes an association between deficiencies in visual perception and motor skills.

Cortical tracking of lexical speech units in a multi-talker background is immature in school-aged children

Children have more difficulty perceiving speech in noise than adults. Whether this difficulty relates to an immature processing of prosodic or linguistic elements of the attended speech is still unclear. To address the impact of noise on linguistic processing per se, we assessed how babble noise impacts the cortical tracking of intelligible speech devoid of prosody in school-aged children and adults.Twenty adults and twenty children (7-9 years) listened to synthesized French monosyllabic words presented at 2.5 Hz, either randomly or in 4-word hierarchical structures wherein 2 words formed a phrase at 1.25 Hz, and 2 phrases formed a sentence at 0.625 Hz, with or without babble noise. Neuromagnetic responses to words, phrases and sentences were identified and source-localized.Children and adults displayed significant cortical tracking of words in all conditions, and of phrases and sentences only when words formed meaningful sentences. In children compared with adults, the cortical tracking was lower for all linguistic units in conditions without noise. In the presence of noise, the cortical tracking was similarly reduced for sentence units in both groups, but remained stable for phrase units. Critically, when there was noise, adults increased the cortical tracking of monosyllabic words in the inferior frontal gyri and supratemporal auditory cortices but children did not.This study demonstrates that the difficulties of school-aged children in understanding speech in a multi-talker background might be partly due to an immature tracking of lexical but not supra-lexical linguistic units.

The role of perceptual difficulty in visual hindsight bias for emotional faces.

Visual hindsight bias, also known as the "saw-it-all-along" effect, is the tendency to overestimate one's perceptual abilities with the aid of outcome knowledge. Recently, Giroux et al. (2022, Emotion, https://doi.org/10.1037/emo0001068 ) reported robust visual hindsight bias for emotional faces except for happy. We examined whether the difficulty of emotional processing could explain their finding. As in Giroux et al., participants saw a blurred image of an emotional face (happy, angry, or neutral) that progressed to clear and were instructed to stop the clearing process when they were able to identify the emotion (foresight trials). They then were shown the clearest image of each face and determined the emotion, followed by a memory task where they were asked to adjust the blur levels to indicate the point at which they had identified the emotion earlier (hindsight trials). Experiment 1 replicated Giroux et al.'s finding, showing that participants stopped the image at a higher degree of blur during the hindsight trials than they had during the foresight trials (i.e., a visual hindsight bias) for the angry and neutral faces but not happy faces. Experiment 2 manipulated the perceptual difficulty of angry and happy faces. While the easy faces replicated the results of Experiment 1, both angry and happy faces produced strong bias when made difficult. A multinomial processing tree model suggests that visual hindsight bias for emotional faces, while robust, is sensitive to perceptual processing difficulties across emotions.

Abstract 9927: Insufficient Monitoring and Inaccurate Evaluation Characterize the Heart Failure Symptom Perception Process

Perceiving symptoms is needed before one can respond to symptoms, but little is known about the difficulties experienced by patients with heart failure (HF) as they engage in the complex processes of symptom monitoring, awareness, and evaluation. Aim: To explore difficulties in symptom perception and describe the characteristics of patients who consistently perceive HF symptoms. Methods: Using a convergent mixed methods design, we enrolled a purposeful sample of 40 adults with an unplanned hospitalization for HF symptom exacerbation. Quantitative data were obtained from the electronic health record and the Self-Care of Heart Failure Index (SCHFI v 7.2, scale scores 0-100, higher score = better self-care). Qualitative data from 1:1 semi-structured interviews exploring the symptom perception process were analyzed using directed content analysis. For data integration, individual difficulties in the SCHFI symptom perception processes of monitoring, awareness, and evaluation were anchored on the qualitative data. Two groups with different symptom perception consistency were identified from interviews. Group differences were examined using independent T, Mann-Whitney, Chi 2 , and Fisher’s Exact tests. Results: The sample was 50% male, 45% non-white, mean age 62 years, and 75% NYHA III-IV. Most (72.5%) demonstrated adequate symptom perception (SCHFI score ≥70). The consistent symptom perception group (n=27, 67.5%) had no difficulties in symptom monitoring, awareness, and evaluation while the inconsistent group reported insufficient symptom monitoring and/or inaccurate symptom evaluation. The consistent group was more experienced with HF and visited the emergency department more frequently in the past year. There were no group differences in age, gender, race, NYHA class, and HF stage (Table 1). Conclusion: Symptom perception interventions may be particularly useful early in the HF trajectory to enhance symptom monitoring and evaluation abilities.

Причины и следствия лингвокреативности в межкультурной коммуникации

The research is devoted to the problems of linguistic creativity in intercultural communication. The features of modern intercultural communication in new digital media are considered: social networks, electronic mass media, and the Internet-communication. The causes of intercultural communicative failures on the topic of international relations are revealed and the role of invective linguistic creativity in the emergence and development of intercultural conflict is established. It is determined that the perception of linguistic innovations in the context of intercultural communication is determined not only by linguistic, but also by cultural and pragmatic factors, and in the modern world it is increasingly burdened with negative evaluation which depends on political and ideological aspects. In the context of international political and economic confrontation, the relevance and aesthetics of linguistic or discursive innovation often becomes one-sided and is interpreted only from the point of view of the addresser. In the examples considered, linguistic creativity in the statements of heads of state in social networks violates the norms of speech behavior, the language standard, causes difficulty in perception, leads to misunderstanding and rejection by interlocutors representing different cultures and languages, and is often invective. In order to avoid communication failures, the relevance and aesthetics of non-standard language forms should be evaluated not only from the point of view of the addresser, but also the recipient of the message, otherwise, unintentionally or intentionally, there is a threat of intercultural communication failure.

Always look on the bright side of logic? Testing explanations of intuitive sensitivity to logic in perceptual tasks.

Much recent research and theorizing in the field of reasoning has been concerned with intuitive sensitivity to logical validity, such as the logic-brightness effect, in which logically valid arguments are judged to have a "brighter" typeface than invalid arguments. We propose and test a novel signal competition account of this phenomenon. Our account makes two assumptions: (a) as per the demands of the logic-brightness task, people attempt to find a perceptual signal to guide brightness judgments, but (b) when the perceptual signal is hard to discern, they instead attend to cues such as argument validity. Experiment 1 tested this account by manipulating the difficulty of the perceptual contrast. When contrast discrimination was relatively difficult, we replicated the logic-brightness effect. When the discrimination was easy, the effect was eliminated. Experiment 2 manipulated the ambiguity of the perceptual task, comparing discrimination performance when the perceptual contrast was labeled in terms of rating "brightness" or "darkness". When the less ambiguous darkness labeling was used, there was no evidence of a logic-brightness effect. In both experiments, individual sensitivity to the perceptual discrimination was negatively correlated with sensitivity to argument validity. Hierarchical latent mixture modeling revealed distinct individual strategies: responses based on perceptual cues, responses based on validity or guessing. Consistent with the signal competition account, the proportion of those responding to validity increased with perceptual discrimination difficulty or task ambiguity. The results challenge explanations of the logic-brightness effect based on parallel dual-process models of reasoning. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Metacognition and self‐regulation on the road: A qualitative approach to driver attention and distraction

AbstractThis study aimed to explore the self‐regulatory experiences and perceptions of drivers' attentional processes on the road, via a metacognitive framework. A total of 46 Australian drivers participated in a phone interview and thematic analysis was applied to the data. The results revealed that effective self‐reported attention regulation was perceptually contingent on: driving experience, metacognitive skills used to regulate attention, and strategies to sustain attention. The perceptual difficulty of driving environments was shown to impact on self‐reported arousal, and thus the perceived ability to control and sustain attention. Similarly, cognitive confidence, and metacognitive beliefs about worry and mindless driving were shown to not only influence the tendency to engage in worry and mindless driving, but also the subjective ability to self‐regulate attention whilst doing so. This study has provided evidence for the potential of metacognitive concepts to help better understand the process of attentional lapses and difficulties on the road.

Problems Encountered by Mathematics and Science Teachers in Classrooms where Syrian Students under Temporary Protection Status are Educated and Suggestions for Solution

In this study, problems encountered by mathematics and science teachers in classrooms where Syrian students under temporary protection status and suggestions for solution to these problems were examined. A case study was used among qualitative research methods. 30 volunteer mathematics and science teachers from three state middle schools in the 2018-2019 academic year have attended the study in which criterion sampling was preferred. In the study where a semi-structured interview form was utilized, evaluation of the data was done through content analysis. As the result of this study, it was determined that Syrian students have problems particularly language and communication problems which are stemming from behavioral, parenting, economic, legislative, and their past lives. Underlying the problems encountered by mathematics and science teachers in their lessons is the Syrian students' not having sufficient language skills and having difficulties in perception and learning. Incompatibility of the curriculum, parents' perspective on education, having difficulties in dealing with problems and lack of materials are among the issues that teachers have problems in. The difficulty acquisition levels and course contents, the level difference between students, and the lack of training in the subjects are among the most common problems encountered by teachers in terms of the dimension of the curriculum. The suggestions of mathematics and science teachers are for the students and families to overcome the language problem, increasing the supplementary courses, providing material support, and providing support for the education of the families.

Acute effects of local vibration and visual feedback on the pelvic floor muscle training in Japanese healthy adults: A cross-over study

BACKGROUND: Those undergoing pelvic floor muscle training (PFMT) often experience difficulty in perception; therefore, an easier PFMT method should be devised. OBJECTIVE: To determine the effectiveness of combining PFMT with either vibration stimulation or visual feedback provided by a branded cushion (not a prototype) in increasing PFM muscle activity. Since PFM does not involve large joint movements, muscle activity was a suitable indicator. METHODS: Twenty healthy adults were included in this study. All participants performed PFMT under three conditions using a branded cushion: vibration stimulation, visual feedback, and a control. All three conditions were provided separately. PFM activity of the midline of the perineum at two points was recorded as the root mean square measured using PFM electromyography, measured twice for each condition. Muscle activity ratio was obtained by calculating maximum voluntary contraction of PFM in pre- and post-PFMT conditions. RESULTS: PFM activity and muscle activity ratio were both significantly higher following PFMT under vibration stimulation and visual feedback conditions (p&lt; 0.01, p&lt; 0.01, respectively). CONCLUSIONS: PFMT accompanied by vibration stimulation or visual feedback could immediately raise PFM muscle activity. We believe this study contributes to improving PFMT efficiency by suggesting more suitable PFMT methods.

Reading Behaviors through Patterns of Finger-Tracking in Italian Children with Autism Spectrum Disorder.

The paper proposes an ecological and portable protocol for the large-scale collection of reading data in high-functioning autism spectrum disorder (ASD) children based on recording the finger movements of a subject reading a text displayed on a tablet touchscreen. By capitalizing on recent evidence that movements of a finger that points to a scene or text during visual exploration or reading may approximate eye fixations, we focus on recognition of written content and function words, pace of reading, and accuracy in reading comprehension. The analysis showed significant differences between typically developing and ASD children, with the latter group exhibiting greater variation in levels of reading ability, slower developmental pace in reading speed, less accurate comprehension, greater dependency on word length and word frequency, less significant prediction-based processing, as well as a monotonous, steady reading pace with reduced attention to weak punctuation. Finger-tracking patterns provides evidence that ASD readers may fail to integrate single word processing into major syntactic structures and lends support to the hypothesis of an impaired use of contextual information to predict upcoming stimuli, suggesting that difficulties in perception may arise as difficulties in prediction.

Focus perception in Japanese: Effects of lexical accent and focus location.

This study explored the contexts in which native Japanese listeners have difficulty identifying prosodic focus. Using a 4AFC identification task, we compared native Japanese listeners’ focus identification accuracy in different lexical accent × focus location conditions using resynthesised speech stimuli, which varied only in fundamental frequency. Experiment 1 compared the identification accuracy in lexical accent × focus location conditions using both natural and resynthesised stimuli. The results showed that focus identification rates were similar with the two stimulus types, thus establishing the reliability of the resynthesised stimuli. Experiment 2 explored these conditions further using only resynthesised stimuli. Narrow foci bearing the lexical pitch accent were always more correctly identified than unaccented ones, whereas the identification rate for final focus was the lowest among all focus locations. From these results, we argue that the difficulty of focus perception in Japanese is attributed to (i) the blocking of PFC by unaccented words, and (ii) similarity in F0 contours between lexical pitch accent and narrow focus, including in particular the similarity between downstep and PFC. Focus perception is therefore contingent on other concurrent communicative functions which may sometimes take precedence in a +PFC language.

Нарушение социального восприятия у больных неврозоподобной шизофренией с обсессивно-фобическим синдромом

Introduction. The study is focused on identifying disorientation in the communication of patients with neurosis-like schizophrenia with obsessive-phobic syndrome. Insufficient scientific development and high medical and social significance of the topic are shown. The assumption is formulated that patients have a pronounced violation of social perception, interconnected with positive, negative symptoms and quality of life. Empirical analysis. The results of the study showed significant difficulties of perception and interpretation of social information, interrelated with clinical symptoms. The leading role is played by rigidity, stereotyped thinking, which determine the fragmentary and superficial perception of emotions, as well as elements of delusional ideas and hallucinations that distort the understanding of social situations. Over the course of the disease, inadequately inflated estimates of life are formed. Social anhedonia mediates the influence of clinical symptoms on social perception, stabilizing the deficits of social perception and intelligence. The length of the disease contributes to life satisfaction in connection with a protective self-attitude and reconciliation with the status of “disabled”. Conclusion. Patients have pronounced difficulties recognizing emotions by facial expressions, posture and gestures associated with positive and negative symptoms. An increase in the subjective assessment of aspects of life in society reflects a protective worldview and self-attitude, as well as a downward drift of standards.
