Trustworthiness judgments and pupil-size in individuals with schizophrenia.

Individuals with schizophrenia show aberrant processing of social cues. In the current study, we (1) compared trustworthiness ratings of faces between patients with schizophrenia and healthy controls, (2) compared pupillary reactivity between patients and controls (3) examined whether trustworthiness judgments in schizophrenia are related to pupil reactivity, (4) and examined associations between trustworthiness judgements and symptom severity, specifically paranoia. Patients with schizophrenia spectrum disorders (N = 48) and healthy controls (N = 33) completed a Trustworthiness Task, during which their pupil size was measured via an eye-tracking device. The mean baseline-corrected pupil size was calculated from 24 pictures of real neutral faces, each presented for 2500ms. Self-reported psychotic experiences were measured by Community Assessment of Psychic Functioning (CAPE-42), and symptom severity was rated by Brief Psychiatric Rating Scale (BPRS). No group differences were found in trustworthiness ratings or pupil reactivity parameters during trustworthiness judgments. Separately, among patients, absolute difference in pupil-size change and dilation after reaching minimum size were related to more severe positive symptoms and self-reported paranoia. Our results did not show social cognitive biases in the stable outpatients with schizophrenia, or the role of pupil reactivity in trustworthiness judgments. Future studies should use longer stimuli for pupillary reactivity and control the type and dosage of utilized antipsychotic medication. Further studies are required to explore relationships in larger and more symptomatic groups of patients.

Strategies, processes, outcomes, and costs of implementing experience sampling-based monitoring in routine mental health care in four European countries: study protocol for the IMMERSE effectiveness-implementation study.

BACKGROUND: Recent years have seen a growing interest in the use of digital tools for delivering person-centred mental health care. Experience Sampling Methodology (ESM), a structured diary technique for capturing moment-to-moment variation in experience and behaviour in service users' daily life, reflects a particularly promising avenue for implementing a person-centred approach. While there is evidence on the effectiveness of ESM-based monitoring, uptake in routine mental health care remains limited. The overarching aim of this hybrid effectiveness-implementation study is to investigate, in detail, reach, effectiveness, adoption, implementation, and maintenance as well as contextual factors, processes, and costs of implementing ESM-based monitoring, reporting, and feedback into routine mental health care in four European countries (i.e., Belgium, Germany, Scotland, Slovakia). METHODS: In this hybrid effectiveness-implementation study, a parallel-group, assessor-blind, multi-centre cluster randomized controlled trial (cRCT) will be conducted, combined with a process and economic evaluation. In the cRCT, 24 clinical units (as the cluster and unit of randomization) at eight sites in four European countries will be randomly allocated using an unbalanced 2:1 ratio to one of two conditions: (a) the experimental condition, in which participants receive a Digital Mobile Mental Health intervention (DMMH) and other implementation strategies in addition to treatment as usual (TAU) or (b) the control condition, in which service users are provided with TAU. Outcome data in service users and clinicians will be collected at four time points: at baseline (t0), 2-month post-baseline (t1), 6-month post-baseline (t2), and 12-month post-baseline (t3). The primary outcome will be patient-reported service engagement assessed with the service attachment questionnaire at 2-month post-baseline. The process and economic evaluation will provide in-depth insights into in-vivo context-mechanism-outcome configurations and economic costs of the DMMH and other implementation strategies in routine care, respectively. DISCUSSION: If this trial provides evidence on reach, effectiveness, adoption, implementation and maintenance of implementing ESM-based monitoring, reporting, and feedback, it will form the basis for establishing its public health impact and has significant potential to bridge the research-to-practice gap and contribute to swifter ecological translation of digital innovations to real-world delivery in routine mental health care.

Bradykinesia in dystonic hand tremor: kinematic analysis and clinical rating.

Introduction: Bradykinesia is an essential diagnostic criterion for Parkinson's disease (PD) but is frequently observed in many non-parkinsonian movement disorders, complicating differential diagnosis, particularly in disorders featuring tremors. The presence of bradykinetic features in the subset of dystonic tremors (DT), either "pure" dystonic tremors or tremors associated with dystonia, remains currently unexplored. The aim of the current study was to evaluate upper limb bradykinesia in DT patients, comparing them with healthy controls (HC) and patients with PD by observing repetitive finger tapping (FT). Methods: The protocol consisted of two main parts. Initially, the kinematic recording of repetitive FT was performed using optical hand tracking system (Leap Motion Controller). The values of amplitude, amplitude decrement, frequency, frequency decrement, speed, acceleration and number of halts of FT were calculated. Subsequently, three independent movement disorder specialists from different movement disorders centres, blinded to the diagnosis, rated the presence of FT bradykinesia based on video recordings. Results: Thirty-six subjects participated in the study (12 DT, 12 HC and 12 early-stage PD). Kinematic analysis revealed no significant difference in the selected parameters of FT bradykinesia between DT patients and HC. In comparisons between DT and PD patients, PD patients exhibited bigger amplitude decrement and slower FT performance. In the blinded clinical assessment, bradykinesia was rated, on average, as being present in 41.6% of DT patients, 27.7% of HC, and 91.7% of PD patients. While overall inter-rater agreement was moderate, weak agreement was noted within the DT group. Discussion: Clinical ratings indicated signs of bradykinesia in almost half of DT patients. The objective kinematic analysis confirmed comparable parameters between DT and HC individuals, with more pronounced abnormalities in PD across various kinematic parameters. Interpretation of bradykinesia signs in tremor patients with DT should be approached cautiously and objective motion analysis might complement the diagnostic process and serve as a decision support system in the choice of clinical entities.

Identity recognition from faces and bodies in schizophrenia spectrum disorders.

Deficits in facial identity recognition and its association with poor social functioning are well documented in schizophrenia, but none of these studies have assessed the role of the body in these processes. Recent research in healthy populations shows that the body is also an important source of information in identity recognition, and the current study aimed to thoroughly examine identity recognition from both faces and bodies in schizophrenia. Sixty-five individuals with schizophrenia and forty-nine healthy controls completed three conditions of an identity matching task in which they attempted to match unidentified persons in unedited photos of faces and bodies, edited photos showing faces only, or edited photos showing bodies only. Results revealed global deficits in identity recognition in individuals with schizophrenia (ηp2 = 0.068), but both groups showed better recognition from bodies alone as compared to faces alone (ηp2 = 0.573), suggesting that the ability to extract useful information from bodies when identifying persons may remain partially preserved in schizophrenia. Further research is necessary to understand the relationship between face/body processing, identity recognition, and functional outcomes in individuals with schizophrenia-spectrum disorders.

Interpersonal distance in schizophrenia: A systematic review.

BACKGROUND AND HYPOTHESIS: Schizophrenia is often associated with severe difficulties in social functioning, resulting in increased isolation and subsequent loneliness. Interpersonal distance - the amount of space around an individual's body during social interaction - can signal such difficulties. However, little is known about how individuals with schizophrenia regulate their interpersonal distance during social encounters. Summarizing the current empirical findings of interpersonal distance regulation in schizophrenia can bring novel perspectives for understanding interpersonal difficulties observed in this clinical population. STUDY DESIGN: This systematic review examined empirical studies indexed in Web of Science and PubMed based on a-priori-defined criteria. 1164 studies were screened with the final review consisting of 14 studies. They together included 1145 adult participants, of whom 668 were diagnosed with schizophrenia or psychotic disorder. STUDY RESULTS: The studies clearly showed that patients maintain greater interpersonal distances than do controls. Furthermore, a larger distance was linked to more severe positive and negative symptoms. More specifically, the link to symptoms was more pronounced when patients were being approached by someone else during interactions. On a neurobiological level, the increased activity and functional connectivity of the dorsal inferior parietal sulcus and increased subjective state-dependent stress are further indicated as being potentially related to increase interpersonal distancing in schizophrenia. CONCLUSIONS: We provided information about the aberrant modulation of interpersonal distance in schizophrenia. Studies showed substantial heterogeneity in tasks used to measure interpersonal distance. Future studies should look at links to social functioning, underlying neurobiology, and neuroendocrinal regulation of interpersonal space in schizophrenia.

Linking social motivation, general motivation, and social cognition to interpersonal functioning in schizophrenia: insights from exploratory graph analysis.

Motivation in general, and social motivation in particular are important for interpersonal functioning in individuals with schizophrenia. Still, their roles after accounting for social cognition, are not well understood. The sample consisted of 147 patients with schizophrenia. General motivation was measured using the Behavioral inhibition/activation scale (BIS/BAS). Social motivation was measured by Passive social withdrawal and Active social avoidance items from PANSS. Interpersonal functioning was evaluated with Birchwood's Social Functioning Scale (SFS). We used Exploratory Graph Analysis for network estimation and community detection. Active social avoidance, passive social withdrawal, and social withdrawal/engagement (from SFS) were the most important nodes. In addition, three distinct communities were identified: Social cognition, Social motivation, and Interpersonal functioning. Notably, the BIS and BAS measures of general motivation were not part of any community. BAS showed stronger links to functioning than BIS. Passive social withdrawal was more strongly linked to interpersonal functioning than social cognitive abilities. Results suggest that social motivation, especially social approach, is more closely related to interpersonal functioning in schizophrenia than general motivation. In contrast, we found that general motivation was largely unrelated to social motivation. This pattern highlights the importance of type of motivation for understanding variability in interpersonal difficulties in schizophrenia.

Temporal pathways from attachment insecurity to paranoia in a heterogeneous clinical sample: An experience sampling study.

INTRODUCTION: There has been growing interest in the role of attachment mechanisms in the onset and maintenance of paranoia. The latest systematic reviews of mixed samples of healthy individuals and psychiatric patients have revealed that increased trait attachment anxiety and avoidance are associated with experiencing paranoia, with trait attachment anxiety showing a stronger association. Few studies have examined attachment and paranoia in naturalistic conditions via the Experience Sampling Method. OBJECTIVES: The present study examined whether experiences of attachment anxiety and avoidance fluctuate in the flow of daily life, and whether a within-person change in both attachment states precedes the experience of momentary paranoia, and negative and positive emotions. METHODS: Thirty-seven clinical participants and twenty-six healthy controls were studied over six consecutive days using the Experience Sampling Method (ESM). An experience-in-close-relationships questionnaire (ECR-R 16 SF) was used to capture trait attachment dimensions. Several ESM items were used to capture momentary negative and positive affect, paranoia and attachment insecurity states. RESULTS: The findings revealed that fluctuations in both attachment insecurity states were significantly higher in the clinical group. A prior elevated attachment anxiety and avoidance was followed by an increase in negative affect in the next moment and elevated attachment avoidance was additionally followed by a decrease in positive affect and an increase in paranoia. CONCLUSION: Our findings reveal the specific temporal associations between momentary attachment insecurity states as predictors of change in emotions/affects and paranoia, along with evidence that state attachment avoidance has a superior impact on momentary affect and paranoia compared to state attachment anxiety. These results contrast with those of recent cross-sectional studies.

Connections between and within extended psychosis and autistic phenotypes and social relationships in the general population.

OBJECTIVES: Non - clinical individuals with higher levels of autistic traits and psychotic experiences also have problems in social relationships. Therefore, this study aimed to model complex associations between autistic and psychotic phenotypes and indicators of social relationships in the general population using a network approach. METHODS: The sample consisted of 649 participants with a mean age of M = 40.23 and SD = 13.09 sampled from the general population. The sample was representative for the 18-65 years old general population in the Slovak Republic. The following scales were administered: Community Assessment of Psychic Experiences, The Comprehensive Autistic Trait Inventory, and NIH Toolbox Adult Social Relationship Scales. Associations between variables and the presence of communities were identified using Exploratory Graph Analysis. RESULTS: Results revealed four highly stable and densely connected communities within the network: social relationships, autistic traits, positive symptoms, and the last one consisting of all negative symptoms, problems in social interactions, and depression. The most important variables in the network were difficulties in social interaction, perceived rejection, bizarre ideas, depression, and social withdrawal. CONCLUSIONS: The psychotic and autistic phenotypes in the general population showed a network of connections with characteristics of social relationships. Community detection revealed that autistic traits and psychotic-like experiences formed relatively independent communities. Further, there was substantial overlap between negative symptoms (e.g., social withdrawal), and core features of the autistic phenotype, especially social interaction difficulties.

Retention in outpatient treatment of alcohol dependence based on the Lesch`s typology and the involvement of a close person.

OBJECTIVES: Retention in alcohol-dependence treatment is an indicator of successful treatment. The aim of this study was to analyze Lesch's typology of alcohol dependence (LAT) and the participation of close people as potential predictors of retention in outpatient treatment. METHODS: Participants were included in the study according to the inclusion criteria. Data were collected over eight visits during a 6-month period. The primary outcome was retention in treatment during the 6-month follow-up period. RESULTS: 119 patients were involved in the study, and 84 (70.6 %) of those patients remained in treatment up to the 6th month. Analysis of retention was performed for the Lesch I, II, and III types, as the type IV patients were underrepresented and had different baseline characteristics. Higher retention was found for Lesch I type patients (78.4 %) in comparison to the merged II and III groups. The presence of close people at planned visits had a significant effect on treatment persistence. CONCLUSIONS: We found no significant difference in the treatment retention of alcohol-dependent patients at the 6-month follow-up. However, a more comprehensive survival analysis indicated a trend of different retention dynamics between the Lesch I and merged Lesch II and III subgroups. Baseline severity of dependence measured by AUDIT score had no significant effect on treatment retention (Tab. 1, Fig. 3, Ref. 35).

Heterogeneity of social cognitive performance in autism and schizophrenia.

Autistic adults and those with schizophrenia (SCZ) demonstrate similar levels of reduced social cognitive performance at the group level, but it is unclear whether these patterns are relatively consistent or highly variable within and between the two conditions. Seventy-two adults with SCZ (52 male, Mage  = 28.2 years) and 94 with diagnoses on the autism spectrum (83 male, Mage  = 24.2 years) without intellectual disability completed a comprehensive social cognitive battery. Latent profile analysis identified four homogeneous subgroups that were compared on their diagnosis, independent living skills, neurocognition, and symptomatology. Two groups showed normative performance across most social cognitive tasks but were differentiated by one having significantly higher hostility and blaming biases. Autistic participants were more likely to demonstrate fully normative performance (46.8%) than participants with SCZ, whereas normative performance in SCZ was more likely to co-occur with increased hostility and blaming biases (36.1%). Approximately 43% of participants in the full sample were classified into the remaining two groups showing low or very low performance. These participants tended to perform worse on neurocognitive tests and have lower IQ and fewer independent living skills. The prevalence of low performance on social cognitive tasks was comparable across clinical groups. However, nearly half of autistic participants demonstrated normative social cognitive performance, challenging assumptions that reduced social cognitive performance is inherent to the condition. Subgrouping also revealed a meaningful distinction between the clinical groups: participants with SCZ were more likely to demonstrate hostility biases than autistic participants, even when social cognitive performance was otherwise in the typical range. LAY SUMMARY: Social cognition refers to the perception and interpretation of social information. Previous research has shown that both autistic people and those with schizophrenia demonstrate reduced performance on traditional social cognitive tasks, which we replicate here at the group level. However, we also found that almost half of autistic participants performed in the normal range. Over a third of participants with schizophrenia did as well, but for them this performance was accompanied by a hostility bias not commonly found in the autistic sample. Taken together, findings challenge assumptions that difficulties in social cognition are a uniform characteristic of these clinical conditions in those without intellectual disability.

Normative data for the Slovak version of the Frontal Assessment Battery (FAB).

The Frontal Assessment Battery (FAB) is a well-established screening measure of frontal lobe pathology. The aim of this study is the development of normative data for healthy Slovak adults. The final sample consisted of 487 healthy adults (54% of them female). The mean age in our sample was M = 55.29 (SD = 19.96). For the whole sample, the mean score on the FAB was 16.46 and the SD was 1.64. The mean score on the MMSE for the whole sample was 28.39 and the SD was 1.43. All participants underwent a complex neuropsychological examination spanning the relevant cognitive domains. FAB scores were found to be negatively associated with age (rs = -0.464, p < 0.001) and positively associated with years of education (rs = 0.199, p < 0.001). FAB scores positively correlated with the performance in MMSE (rs = 0.266, p < 0.001). Statistically significant and theoretically meaningful associations to other neuropsychological tests used in this study suggested the adequate convergent validity of the Slovak version of the FAB. The present study provided accurate normative FAB data, which can be used for clinical and research purposes.

Social cognition, neurocognition, symptomatology, functional competences and outcomes in people with schizophrenia - A network analysis perspective.

BACKGROUND: Extensive difficulties in reaching functional milestones characterize schizophrenia and related psychotic disorders. These impairments are in part explained by lower social cognitive abilities, cognitive impairment, and current psychopathology. The present study aims to model dynamic associations among social cognition, neurocognition, psychopathology, social skills, functional capacity, and functional outcomes in schizophrenia using network analysis in order to identify those factors that are most central to functioning. METHODS: The sample consisted of 408 patients with schizophrenia spectrum disorders who were drawn from the SCOPE project. Participants completed a complex battery of state-of-the-art measures of social cognition, neurocognition, and functional outcomes. Gaussian Graphical Modeling was used for estimation of the network structure. Accuracy of the network was evaluated using the Bootstrap method. RESULTS: Data supported the importance of functional capacity and social skills, which are prerequisites to real - world outcomes. These variables were among the most central in the network. Social cognition was related to functional capacity, social skills, and real - world functioning. Negative symptoms were connected to functional capacity, social skills, and real - world functioning. CONCLUSIONS: Predictors of functional outcomes are complexly associated with each other. Functional capacity, social - skills, working memory, negative symptoms, mentalizing, and emotion recognition were central nodes that support their importance as potential targets of personalized intervention.

Slovak version of the Trail Making Test: Normative data.

The Trail Making Test (TMT) is a popular measure of cognitive functioning, especially processing speed and cognitive flexibility. This study aims to provide normative data for the Slovak adult population. The secondary aim is to test the convergent validity by examining relationships of direct and derived indices to other neuropsychological measures. A sample of 487 healthy adults undertook neuropsychological testing. The relationships of TMT scores to demographic variables and other neuropsychological measures were tested. Age was positively correlated with TMT-A (r = 0.444, p < .01), TMT-B (r = 0.426, p < .01), and the B-A index (r = 0.317, p < .01). Years of education were negatively correlated with TMT-B (r = -0.183, p < .01), B-A difference (r = -0.188, p < .01) and B/A ratio (r = -0.119, p < .01). There were no statistically significant differences in performance based on gender. The test scores were correlated with other measures of processing speed and executive functions. Presented normative data are stratified into 7 age categories. For more accurate interpretation, regression equations were calculated to take years of education into account. TMT-A and B performance, as well as B-A difference score, must be interpreted in relation to age, while education can provide additional information. The B/A ratio is independent from age but should be also corrected for educational level.

Psycho-social factors associated with mental resilience in the Corona lockdown.

The SARS-CoV-2 pandemic is not only a threat to physical health but is also having severe impacts on mental health. Although increases in stress-related symptomatology and other adverse psycho-social outcomes, as well as their most important risk factors have been described, hardly anything is known about potential protective factors. Resilience refers to the maintenance of mental health despite adversity. To gain mechanistic insights about the relationship between described psycho-social resilience factors and resilience specifically in the current crisis, we assessed resilience factors, exposure to Corona crisis-specific and general stressors, as well as internalizing symptoms in a cross-sectional online survey conducted in 24 languages during the most intense phase of the lockdown in Europe (22 March to 19 April) in a convenience sample of N = 15,970 adults. Resilience, as an outcome, was conceptualized as good mental health despite stressor exposure and measured as the inverse residual between actual and predicted symptom total score. Preregistered hypotheses (osf.io/r6btn) were tested with multiple regression models and mediation analyses. Results confirmed our primary hypothesis that positive appraisal style (PAS) is positively associated with resilience (p < 0.0001). The resilience factor PAS also partly mediated the positive association between perceived social support and resilience, and its association with resilience was in turn partly mediated by the ability to easily recover from stress (both p < 0.0001). In comparison with other resilience factors, good stress response recovery and positive appraisal specifically of the consequences of the Corona crisis were the strongest factors. Preregistered exploratory subgroup analyses (osf.io/thka9) showed that all tested resilience factors generalize across major socio-demographic categories. This research identifies modifiable protective factors that can be targeted by public mental health efforts in this and in future pandemics.

Processing moving visual scenes during upright stance in elderly patients with mild cognitive impairment.

BACKGROUND: The ability to maintain balance in an upright stance gradually worsens with age and is even more difficult for patients with cognitive disorders. Cognitive impairment plays a probable role in the worsening of stability. The purpose of this study was to expose subjects with mild cognitive impairment (MCI) and healthy, age-matched controls to moving visual scenes in order to examine their postural adaptation abilities. METHODS: We observed postural responses to moving visual stimulation while subjects stood on a force platform. The visual disturbance was created by interposing a moving picture in four directions (forward, backward, right, and left). The pre-stimulus (a static scene for 10 s), stimulus (a dynamic visual scene for 20 seconds) and post-stimulus (a static scene for 20 seconds) periods were evaluated. We separately analyzed the total path (TP) of the center of pressure (COP) and the root mean square (RMS) of the COP displacement in all four directions. RESULTS: We found differences in the TP of the COP during the post-stimulus period for all stimulus directions except in motion towards the subject (left p = 0.006, right p = 0.004, and away from the subject p = 0.009). Significant RMS differences between groups were also observed during the post-stimulus period in all directions except when directed towards the subject (left p = 0.002, right p = 0.007, and away from the subject p = 0.014). CONCLUSION: Exposing subjects to a moving visual scene induced greater destabilization in MCI subjects compared to healthy elderly controls. Surprisingly, the moving visual scene also induced significant aftereffects in the MCI group. Our findings indicate that the MCI group had diminished adaptation to the dynamic visual scene and recovery. These results suggest that even mild cognitive deficits can impair sensory information integration and alter the sensory re-weighing process.

Psychometric properties of the Observable Social Cognition Rating Scale (OSCARS): Self-report and informant-rated social cognitive abilities in schizophrenia.

Individuals with schizophrenia spectrum disorders (SSD) consistently show deficits in social cognition (SC) which is associated with real world outcomes. Psychosocial treatments have demonstrated reliable improvements in SC abilities, highlighting the need for accurate identification of SC deficits for efficient and individualized treatment planning. To this end, the Observable Social Cognition Rating Scale (OSCARS) is an 8-item scale with both self and informant versions. This study investigated psychometric properties of the OSCARS as both a self and informant-reported scale in a large sample of SSD (n = 382) and individuals without a psychiatric diagnosis (n = 289). A two-factor structure (Social Cognitive Bias and Social Cognitive Ability) of the OSCARS demonstrated acceptable model fit with good internal consistency for both self- and informant-report. The OSCARS had adequate convergent, external, and predictive validity. Area Under the Curve (AUC) values suggest the OSCARS has some value in identifying individuals with impaired SC and social competence, although stronger AUC values were demonstrated when identifying individuals with impaired real-world functioning. Overall, psychometric properties indicate the OSCARS may be a useful first-step tool for clinicians to detect functioning deficits in SSD and efficiently identify individuals in need of additional assessment or psychosocial interventions.

Temporal associations between sleep quality and paranoia across the paranoia continuum: An experience sampling study.

Sleep disturbances are prevalent among individuals with a psychotic disorder and have been linked to symptoms of paranoia across the entire psychosis continuum. Emerging evidence suggests that rather than a secondary symptom, poor quality of sleep may contribute to elevated paranoid ideation. We investigated the temporal dynamics of sleep quality and paranoid ideation using the experience sampling method in 42 acutely paranoid individuals with a psychotic disorder, 32 nonparanoid individuals with psychotic disorder, and 41 individuals with high schizotypy traits. We applied time-lagged mixed multilevel modeling to tease apart the effect of poor sleep quality on morning paranoia and negative affect, and the impact of evening paranoid ideation and negative affect on subsequent sleep quality. In the whole sample, poor subjective sleep quality predicted elevated paranoia the following morning, a relationship that was fully mediated by morning negative affect. No significant association between evening paranoia and poor sleep the following night emerged. In the everyday lives of individuals on the paranoia continuum, low quality of sleep appears to drive paranoia through its impact on negative affect. These findings identify sleep quality as an important target of transdiagnostic interventions for psychotic and affective symptomatology.

Implicit and explicit processing of bodily emotions in schizophrenia.

INTRODUCTION: Disturbed emotion processing is well documented in schizophrenia, but the majority of studies evaluate processing of emotion only from facial expressions. Social cues are also communicated via body posture, and they are similarly relevant for successful social interactions. The aim of the current study was to thoroughly examine body perception abilities in individuals with schizophrenia. METHODS: Fifty-nine patients with schizophrenia and 37 healthy controls completed two tasks of body processing. The first, which was based on the Affect Misattribution Procedure, evaluated implicit processing of bodily emotions, and the second utilised a traditional emotion identification paradigm to assess explicit emotion recognition. RESULTS: Results revealed aberrant implicit processing, but more normative explicit processing, in individuals with schizophrenia. Moderate associations were found between processing of bodies and symptoms of paranoia. Performance on the tasks was not related to cognitive functioning but was associated with clinician-rated social functioning. CONCLUSIONS: Collectively, these results provide information about disturbed processing of bodily emotions in schizophrenia and suggest that these disturbances are associated with the severity of positive symptoms and predict difficulties in everyday social activities and interpersonal relationships.
