Mental States in Moving Shapes: Distinct Cortical and Subcortical Contributions to Theory of Mind Impairments in Dementia.

Impaired capacity for Theory of Mind (ToM) represents one of the hallmark features of the behavioral variant of frontotemporal dementia (bvFTD) and is suggested to underpin an array of socioemotional disturbances characteristic of this disorder. In contrast, while social processing typically remains intact in Alzheimer's disease (AD), the cognitive loading of socioemotional tasks may adversely impact mentalizing performance in AD. Here, we employed the Frith-Happé animations as a dynamic on-line assessment of mentalizing capacity with reduced incidental task demands in 18 bvFTD, 18 AD, and 25 age-matched Controls. Participants viewed silent animations in which geometric shapes interact in Random, Goal-Directed, and ToM conditions. An exclusive deficit in ToM classification was observed in bvFTD relative to Controls, while AD patients were impaired in the accurate classification of both Random and ToM trials. Correlation analyses revealed robust associations between ToM deficits and carer ratings of affective empathy disruption in bvFTD, and with episodic memory dysfunction in AD. Voxel-based morphometry analyses further identified dissociable neural correlates contingent on patient group. A distributed network of medial prefrontal, frontoinsular, striatal, lateral temporal, and parietal regions were implicated in the bvFTD group, whereas the right hippocampus correlated with task performance in AD. Notably, subregions of the cerebellum, including lobules I-IV and V, bilaterally were implicated in task performance irrespective of patient group. Our findings reveal new insights into the mechanisms potentially mediating ToM disruption in dementia syndromes, and suggest that the cerebellum may play a more prominent role in social cognition than previously appreciated.

A Study on the Theory of Mind Deficits and Delusions in Schizophrenic Patients

ABSTRACTPurpose: This study was conducted to find differences between patients with schizophrenia and healthy control group in ToM and to examine relationships among intelligence, ToM, and delusion in patients with schizophrenia. Methods: Data was collected from 50 patients of schizophrenia and 32 healthy subjects. Participants were given the psychological test form with structured questionnaire. The SPSS 22.0 program was used for t-test, ANCOVA, and, Pearson's Correlation. Measurements used for this study were Korean-Wechsler intelligence scale, three types of Theory of Mind test (Hinting task, False belief task, and Emotional attribution test), and Peters delusion inventory. Results: Performances of the ToM and intelligence in patients were lower than healthy controls. After controlling the impact of IQ, education level, and age, there was a difference between patients and healthy controls on the performance of the Hinting task (F(1,83) = 10.03, p =.002). Correlation analysis showed that the score of false belief task was correlated with delusion (r = −.360, p <.01) and intelligence (r =.449, p <.01). The emotional attribution task was correlated with intelligence (r = 0.309, p <.05). Conclusions: Through the finding of this study, theory of mind is highly recommended as a new target factor considering to develop nursing interventions for schizophrenia.

Cognitive abilities and theory of mind in explaining communicative-pragmatic disorders in patients with schizophrenia

Patients with schizophrenia usually show an impairment in their communicative-pragmatic performance; they also have difficulties in cognitive functioning and Theory of Mind (ToM). In the literature it has been proposed that ToM and cognitive deficits have a role in explaining the communicative-pragmatic difficulties of patients with schizophrenia. However, the exact interplay of these functions is still not completely clear. The present research investigates the relationship between communicative-pragmatic, ToM and cognitive impairments (i.e. general intelligence, selective attention, speed processing and EF -working memory, inhibition and flexibility-) in a sample of 26 individuals with schizophrenia and matched controls. The linguistic and extralinguistic scales of the Assessment Battery of Communication (ABaCo), and a series of ToM and cognitive tasks were administered to patients and healthy controls. The results showed that individuals with schizophrenia performed less well than controls in all the tasks investigated. However, a hierarchical regression analysis showed that only ToM, and not cognitive functions, seems to be a predictive variable of patients’ performance. Finally, a Fisher's exact test showed that there was not a stable significant relationship between ToM or EF and pragmatic impairment.

Theory of mind and schizophrenia in young and middle-aged patients: Influence of executive functions

Theory of Mind (ToM) is compromised in schizophrenia, and responsible for social disability. We aim to study the correlation between ToM deficits and Executive Functions (EF), using the Faux Pas Test (FPT) for ToM evaluation, Behavioral Assessment of the Dysexecutive Syndrome (BADS) and Wisconsin Card Sorting Test (WCST) for EF assessment. Two groups of patients with schizophrenia were included: 22 young (18–35 years-old) and 18 middle-aged (>50 years-old) Patients, compared to age-matched Controls.We found worst FPT performances in both groups of patients, but with a more generalized pattern of dysfunction in the middle-aged patient group. This group had worse EF scores than both controls and younger patients. The association of EF with FPT items was uneven. In young patients only empathy (Q6) remained significant after controlling for EF and level of education, while in middle-aged patients faux pas explanation (Q4), false belief (Q5) and total scores remained significant. In young patients only affective TOM was impaired. No correlation was found with clinical symptoms, nor age at onset of the disease.We conclude that ToM deficit arises early during the course of the illness (already present in young patients), increases in middle-aged patients, and relates only partially with EF.

Theory of Mind and the Detection of Suspicious Behavior

Two studies examined whether deficits in theory of mind—the ability to understand and predict the intent, behaviors, and emotions of others—are related to slowness in recognizing that there is something suspicious about the way in which an interaction is unfolding. Participants listened to vignettes, some culminating in a crime, and indicated when they detected something suspicious about the situation unfolding in the scenario. Theory of mind was assessed using the Frith-Happe animations task, which requires the identification of mental states and emotions of pairs of interacting animated geometric stimuli ( White, Coniston, Rogers, & Frith, 2011 ). A meta-analysis of the studies found meaningful—albeit relatively weak—negative relationships between latency to react to cues to suspicious behavior and performance on the theory of mind measure. Ways to refine this novel paradigm that might sharpen the relationship between the key variables are discussed.

Theory of Mind and Executive Functions are Dissociated in Multiple Sclerosis.

To investigate the relationship of executive functions (EF) and theory of mind (ToM) in multiple sclerosis (MS), clarifing whether ToM impairment in MS is related to EF dysfunction or whether they represent dissociable processes which can be independently impaired in MS. We enrolled 60 consecutive MS patients and 60 healthy controls (HC) matched on age, gender, and education level. All participants underwent ToM testing using the Eyes Test and the Videos Test and neuropsychological testing tapping different EF subdomains. A correlation analysis and a hierarchical cluster analysis were used to determine the similarity between explained variance between EF measures and ToM tests. MS patients had lower scores on both tasks of ToM compared to HC, i.e., Eyes Test (21.1 ± 5.0 vs. 29.5 ± 3.8, p < .001; Cohen's d: 1.9) and Videos Test (19.6 ± 2.4 vs. 22.9 ± 1.8, p < .001; Cohen's d: 1.6). They also performed significantly worse on different measures of EF. ToM performance was not significantly correlated with EF tests. The hierarchical cluster analysis showed that ToM measures in MS were clustered separately from the EF measures, revealing three executive clusters (Attention/working memory cluster; Inhibitory control/shifting ability cluster; Verbal Initiative/Abstract reasoning cluster) and one ToM cluster. This study suggests a dissociation of EF and ToM in MS, meaning that the MS-related neurobehavioral symptoms may be associated with a significant impairment in ToM independent of the level of EF performance. Ultimately, this discrimination of ToM deficits in MS may help to identify the appropriate cognitive and behavioral interventions.

Scalar Implicature in Absence of Epistemic Reasoning? The Case of Autism Spectrum Disorder

ABSTRACTWe investigated “scalar implicature” in adolescents and children with autism spectrum disorder (ASD) to test whether theory of mind deficits associated with autism affect pragmatic inferences in language. We tested scalar implicature computation in adolescents with ASD (12–18 years) and asked whether they reason about mental states when computing inferences. Like previous studies, we found the adolescents with ASD computed implicatures to the same degree as neurotypical adults. However, we also found that this ability may not rely on epistemic reasoning. In a test of epistemic reasoning (which probed so-called “ignorance implicature”) we found that adolescents with ASD were able to make epistemic inferences required by Gricean models of scalar implicature when they were explicitly required by the task to do so. However, in a second task, which asked whether subjects spontaneously reason about mental states in the service of scalar implicature when not explicitly asked to, we found that adolescents with ASD did not engage in epistemic reasoning, leading them to compute scalar implicatures in contexts in which they were not justified. Based on these data, we argue that epistemic reasoning may not be a core, constitutive component of scalar implicature.

Longitudinal reciprocity between theory of mind and aggression in middle childhood

Theory of mind is one of the most important cognitive factors in social information-processing, and deficits in theory of mind have been linked to aggressive behavior in childhood. The present longitudinal study investigated reciprocal links between theory of mind and two forms of aggression – physical and relational – in middle childhood with three data waves over 3 years. Theory of mind was assessed by participants’ responses to cartoons, and physical and relational aggression were assessed through teacher reports in a community sample of 1657 children (mean age at Time 1: 8 years). Structural equation modeling analyses showed that theory of mind was a negative predictor of subsequent physical and relational aggression, both from Time 1 to Time 2 as well as from Time 2 to Time 3. Moreover, relational aggression was a negative predictor of theory of mind from Time 1 to Time 2. There were no significant gender or age differences in the tested pathways. The results suggest that reciprocal and negative longitudinal relations exist between children’s theory of mind and aggressive behavior. Our study extends current knowledge about the development of such relations across middle childhood.

Theory of mind in multiple sclerosis: A neuropsychological and MRI study.

Social cognition stands among the most frequently affected yet the least studied cognitive domains in multiple sclerosis (MS). Theory of mind (ToM) is a social cognitive facet that implies the one's ability to predict others' mental states. The objective of this study was to assess the relationship between ToM and neuropsychological and neuroimaging data. Thirty-eight consecutive MS patients completed the Reading the Mind in the Eyes test (RMET). They underwent a neuropsychological evaluation and a 3T T1-weighted brain MRI. A fully automated volume-based morphometry algorithm (MorphoBox) was applied to calculate regional brain volumes. Correlation analysis was performed using Spearman's test. Among the sociodemographic and clinical data, significant correlations were found between RMET scores and each of years of education (r=0.54; p<0.01) and the duration of the disease progressive phase (r=-0.46; p<0.01). Regarding neuropsychological measures, RMET scores were directly correlated with information processing speed (r=0.58; p<0.01) and empathy (r=0.46; p<0.01) scores. As for brain volumes, RMET scores were directly correlated with parietal (left: r=0.39; right: r=0.46; p<0.05) and temporal (left: r=0.36; right: r=0.40; p<0.05) white matter volumes, as well as with cingulate (left: r=0.32; right: r=0.44; p<0.05) gray matter volumes. These results highlight the relationship between ToM and some of the disease characteristics and cognitive domains. Importantly, ToM performance in MS is associated with brain volumes of key areas in social cognitive networks. Further works are needed to enhance the current knowledge on the underlying mechanisms of ToM deficits in this population.

Theory of Mind in the Early Course of Schizophrenia

Theory of mind deficit is a core feature of schizophrenia and is considered a vulnerability marker of the disorder. The majority of studies measuring theory of mind in schizophrenia involve multiple-episode or chronic schizophrenia patients, and therefore it is important to delineate whether these deficits occur before or following illness-onset by assessing high-risk subjects (clinical high risk and ultra-high risk), early-onset psychosis, and first-degree relatives. We address the question of whether theory of mind impairment is specific or a facet of general cognitive impairment in these clinical populations, and incorporate genetic and neuroimaging studies on the theory of mind. The review provides a succinct evaluation of the literature, discusses current limitations and proposes future directions. Keywords: Theory of mind, adolescence, neuroimaging, social cognition, unaffected relatives, high risk, endophenotype, mentalising.

Neural correlates of "Theory of Mind" in very preterm born children.

Very preterm (VPT) birth (<32 weeks' gestational age) has been implicated in social-cognitive deficits including Theory of Mind (ToM); the ability to attribute mental states to others and understand that those beliefs can differ from one's own or reality. The neural bases for ToM deficits in VPT born children have not been examined. We used magnetoencephalography (MEG) for its excellent spatial and temporal resolution to determine the neural underpinnings of ToM in 24 VPT and 24 full-term born (FT) children (7-13 years). VPT children performed more poorly on neuropsychological measures of ToM but not inhibition. In the MEG task, both FT children and VPT children recruited regions involved in false belief processing such as the rIFG (VPT: 275-350 ms, FT: 250-375 ms) and left inferior temporal gyrus (VPT: 375-450 ms, FT: 325-375 ms) and right fusiform gyrus (VPT: 150-200 ms, FT: 175-250 ms). The rIPL (included in the temporal-parietal junction) was recruited in FT children (475-575 ms) and the lTPJ in VPT children (500-575 ms). However, activations in all regions were reduced in the VPT compared to the FT group. We suggest that with increasing social-cognitive demands such as varying the type of scenarios in the standardized measure of ToM, reduced activations in the rIFG and TPJ in the VPT group may reflect the decreased performance. With access to both spatial and temporal information, we discuss the role of domain general and specific regions of the ToM network in both groups.

Meta-Analysis of Social Cognition in Mild Cognitive Impairment.

Social cognitive abilities are impaired in Alzheimer disease and other dementias. Recent studies suggested that social cognitive abilities might be also impaired in mild cognitive impairment (MCI). Current meta-analysis aimed to summarize available evidence for deficits in theory of mind (ToM) and emotion recognition in MCI. In this meta-analysis of 17 studies, facial emotion recognition and ToM performances of 513 individuals with MCI and 693 healthy controls were compared. Mild cognitive impairment was associated with significant impairments falling in the medium effect sizes range in ToM ( d = 0.63) and facial emotion recognition ( d = 0.58). Among individual emotions, recognition of fear and sadness were particularly impaired. There were no significant between-group differences in recognition of disgust, happiness, and surprise. Social cognitive deficits were more severe in multidomain MCI. There is a need for longitudinal studies investigating the potential role of social cognitive impairment in predicting conversion to dementia.

Neurological soft signs, but not theory of mind and emotion recognition deficit distinguished children with ADHD from healthy control

Attention Deficit Hyperactivity Disorder (ADHD) is associated with social cognition impairment, executive dysfunction and motor abnormalities, consisting in the persistence of neurological soft signs (NSS). Theory of mind (ToM) and emotion recognition (ER) deficit of children with ADHD have been interpreted as a consequence of their executive dysfunction, particularly inhibitory control deficit. To our knowledge, there are not studies that evaluate the possible correlation between the ToM and ER deficit and NSS in the population with ADHD, while this association has been studied in other psychiatric disorders, such as schizophrenia. Therefore, the aim of this study was to evaluate ToM and ER and NSS in a sample of 23 drug-naïve children with ADHD and a sample of 20 healthy children and the possible correlation between social cognition dysfunction and NSS in ADHD. Our findings suggest that ToM and ER dysfunction is not a constant feature in the population with ADHD, while NSS confirmed as a markers of atypical neurodevelopment and predictors of the severity of functional impairment in children with ADHD.

Cognitive Correlates of Different Mentalizing Abilities in Individuals with High and Low Trait Schizotypy: Findings from an Extreme-Group Design.

Mentalizing or Theory of Mind (ToM) deficits in schizophrenia have been studied to great extent, but studies involving samples of trait schizotypy yield ambiguous results. Executive functions like cognitive inhibition, cognitive flexibility, and agency are all prerequisites of mentalizing, and it is assumed that the impairment of these functions contributes to ToM deficits in schizophrenia. Whether these impairments influence the ToM performance of people with high trait schizotypy remains unclear. Although impaired self-agency has repeatedly been identified in people with schizotypy, its role in mentalizing is yet to be investigated. The main aim of this study was to explore whether deficits in cognitive and affective ToM can be found in high trait schizotypy, and to identify in what way these deficits are related to the positive and negative dimensions of schizotypy. The secondary aim was to examine whether these deficits correlate with executive functions. Based on the dimensional view of the schizophrenia spectrum, an extreme-group design was applied to non-clinical volunteers demonstrating high (N = 39) and low (N = 47) trait schizotypy. Affective and cognitive ToM were investigated using the Movie for Assessment of Social Cognition, a sensitive and video-based measurement. Cognitive inhibition was assessed using the Stroop Test, and cognitive flexibility was analyzed using the Trail-Making Test. Agency was measured using a computerized self-agency paradigm. Participants in the high-schizotypy group performed significantly worse in the affective ToM task (d = 0.79), and their overall ToM performance was significantly impaired (d = 0.60). No between-group differences were found with regards to cognitive ToM, executive functions, and self-agency. Cognitive flexibility correlated negatively with positive schizotypy, and contributed to a worse overall and affective ToM. Impaired cognitive inhibition contributed to undermentalizing-type errors. It was found that non-clinical participants with high trait (positive) schizotypy – especially those with slight executive-function deficits – may have difficulties in understanding the emotional state of others and consequently in functioning in social situations.

Examining differences in cognitive and affective theory of mind between persons with high and low extent of somatic symptoms: an experimental study

BackgroundMedically unexplained somatic symptoms are common, associated with disability and strongly related to depression and anxiety disorders. One interesting, but to date rarely tested, hypothesis is that deficits in both theory of mind (ToM) and emotional awareness may undergird the phenomenon of somatization. This study sought to investigate whether or not differences in ToM functioning and self-reported emotional awareness are associated with somatic symptoms in a sample from the general population.MethodsThe sample consisted of 50 healthy participants (37 females, 13 males) aged between 22 and 64 years (46.8 ± 11.7) of whom 29 reported a high extent of somatic symptoms (HSR), whereas 21 reported a low extent of somatic symptoms (LSR) based on the 30 highest and lowest percentiles of the Symptom List norms. The participants’ affective and cognitive ToM were assessed with two experimental paradigms by experimenters who were blind to the participants’ group membership. In addition, self-reports regarding emotional awareness, alexithymia, depressive and anxiety symptoms and current affect were collected.ResultsIn the experimental tasks, HSR showed lower affective ToM than LSR but the groups did not differ in cognitive ToM. Although HSR reported lower emotional awareness than LSR in the self-report measure, this group difference vanished when we controlled for anxiety and depression. Depression, anxiety, emotional awareness and alexithymia were correlated positively.ConclusionsThe data supported the hypothesis that deficits in affective ToM are related to somatic symptoms. Neither cognitive ToM nor self-reported emotional awareness were associated with somatic symptoms. Self-reported emotional awareness, alexithymia and symptoms of depression and anxiety shared a considerable amount of variance.

Uncovering the neuroanatomical correlates of cognitive, affective and conative theory of mind in paediatric traumatic brain injury: a neural systems perspective.

Deficits in theory of mind (ToM) are common after neurological insult acquired in the first and second decade of life, however the contribution of large-scale neural networks to ToM deficits in children with brain injury is unclear. Using paediatric traumatic brain injury (TBI) as a model, this study investigated the sub-acute effect of paediatric traumatic brain injury on grey-matter volume of three large-scale, domain-general brain networks (the Default Mode Network, DMN; the Central Executive Network, CEN; and the Salience Network, SN), as well as two domain-specific neural networks implicated in social-affective processes (the Cerebro-Cerebellar Mentalizing Network, CCMN and the Mirror Neuron/Empathy Network, MNEN). We also evaluated prospective structure–function relationships between these large-scale neural networks and cognitive, affective and conative ToM. 3D T1- weighted magnetic resonance imaging sequences were acquired sub-acutely in 137 children [TBI: n = 103; typically developing (TD) children: n = 34]. All children were assessed on measures of ToM at 24-months post-injury. Children with severe TBI showed sub-acute volumetric reductions in the CCMN, SN, MNEN, CEN and DMN, as well as reduced grey-matter volumes of several hub regions of these neural networks. Volumetric reductions in the CCMN and several of its hub regions, including the cerebellum, predicted poorer cognitive ToM. In contrast, poorer affective and conative ToM were predicted by volumetric reductions in the SN and MNEN, respectively. Overall, results suggest that cognitive, affective and conative ToM may be prospectively predicted by individual differences in structure of different neural systems—the CCMN, SN and MNEN, respectively. The prospective relationship between cerebellar volume and cognitive ToM outcomes is a novel finding in our paediatric brain injury sample and suggests that the cerebellum may play a role in the neural networks important for ToM. These findings are discussed in relation to neurocognitive models of ToM. We conclude that detection of sub-acute volumetric abnormalities of large-scale neural networks and their hub regions may aid in the early identification of children at risk for chronic social-cognitive impairment.

Role of Two Types of Syntactic Embedding in Belief Attribution in Adults with or without Asperger Syndrome.

The role of syntax in belief attribution (BA) is not completely understood in healthy adults and understudied in adults with autism spectrum disorder. Embedded syntax could be useful either for the development of Theory of Mind (ToM) (Emergence account) or more generally over the lifespan (Reasoning account). Two hypotheses have been explored, one suggesting that embedding itself (Relatives and Complement sentences and Metarepresentation account) is important for ToM and another one considering that the embedding of a false proposition into a true one (Complement sentences and Misrepresentation account) is important. The goals of this study were to evaluate (1) the role of syntax in ToM (Emergence vs. Reasoning account), (2) the type of syntax implied in ToM (Metarepresentation vs. Misrepresentation account), and (3) the verbally mediated strategies which compensate for ToM deficits in adults with Asperger Syndrome (AS). Fifty NeuroTypical (NT) adults and 22 adults with AS were involved in a forced-choice task including ±ToM tasks (BA and a control task, physical causation, PC) under four Interference conditions (silence, syllable repetition, relative sentences repetition, and complement sentences repetition). The non-significant ±ToM × Interference interaction effect in the NT group did not support the Reasoning account and thus suggests that syntax is useful only for ToM development (i.e., Emergence account). Results also indicated that repeating complement clauses put NT participants in a dual task whereas repeating relative clauses did not, suggesting that repeating relatives is easier for NT than repeating complements. This could be an argument in favor of the Misrepresentation account. However, this result should be interpreted with caution because our results did not support the Reasoning account. Moreover, AS participants (but not NT participants) were more disrupted by ±ToM tasks when asked to repeat complement sentences compared to relative clause sentences. This result is in favor of the Misrepresentation account and indirectly suggests verbally mediated strategies for ToM in AS. To summarize, our results are in favor of the Emergence account in NT and of Reasoning and Misrepresentation accounts in adults with AS. Overall, this suggests that adults with AS use complement syntax to compensate for ToM deficits.

Theory of mind deficits partly mediate impaired social decision-making in schizophrenia

BackgroundUsing paradigms from game theory, researchers have reported abnormal decision-making in social context in patients with schizophrenia. However, less is known about the underpinnings of the impairment. This study aimed to test whether theory of mind (ToM) deficits and/or neurocognitive dysfunctions mediate impaired social decision-making in patients with schizophrenia.MethodsWe compared thirty-five patients with schizophrenia to thirty-eight matched healthy controls with regard to social decision-making using the mini Ultimatum Game (mini UG), a paradigm from game theory. Additionally, we assessed ToM using the Theory of Mind Picture Stories Task, a mental state attribution task, and assessed neurocognition using the Brief Assessment of Cognition in Schizophrenia. Mediation analyses were performed on the data.ResultsIn contrast to the behavioral pattern of healthy controls in the mini UG, the patients with schizophrenia significantly accepted more disadvantageous offers and rejected more advantageous offers, and showed reduced sensitivity to the fairness-related context changes in the mini UG. Impaired ToM and neurocognition were also found in the patients. Mediation analyses indicated that ToM but not neurocognition partially mediated the group differences on the disadvantageous and advantageous offers in the mini UG.ConclusionsPatients with schizophrenia exhibited impaired social decision-making. This impairment can be partly explained by their ToM deficits rather than neurocognitive deficits. However, the exact nature of the ToM deficits that mediate impaired social decision-making needs to be identified in future.

Social cognition and communication skills in Asperger syndrome young adults

Abstract: The aim of this study is to compare patients with Asperger syndrome (AS) and control participants on social cognition tasks and communication skills. Twenty young adults were assessed in three social cognition domains; recognition of basic emotions, recognition of complex emotions and Theory of Mind (ToM). In addition participants completed a self-report questionnaire as a measure of social communication skills. The results indicate that adults with AS perform below neurotypical control participants in emotion processing, ToM and communication skills. There were no significant correlations between the variables of social cognition and communication skills in the group of AS. Taken together, results suggest that people with a diagnosis of AS present a deficit in ToM and emotional processing as well as in communication skills. However, it was not possible to identify a significant association between the variables of social cognition and communication skills. Cognición social y habilidades de comunicación en adultos jóvenes con síndrome de Asperger Resumen: El objetivo de este trabajo es estudiar la ejecución de personas con síndrome de Asperger (AS) en tareas de cognición social y de habilidades comunicacionales. Para ello se evaluaron veinte adultos jóvenes en tres áreas de la cognición social, reconocimiento de emociones básicas, reconocimiento de emociones complejas y Teoría de la Mente (ToM). Además los participantes completaron un autoinforme sobre habilidades de comunicación social. Los resultados indican que los adultos con SA obtienen una peor ejecución en las tareas de procesamiento de las emociones (tanto básicas como complejas), en tareas de ToM y en habilidades de comunicación. No se han obtenido correlaciones significativas entre las variables de cognición social y las habilidades de comunicación. En conjunto, los resultados sugieren que las personas con un diagnóstico de SA presentan un déficit en el procesamiento emocional y de ToM, así como en las habilidades de comunicación. Sin embargo, no fue posible identificar una asociación significativa entre las diferentes variables de cognición social evaluadas y las habilidades de comunicación.

Do specific metacognitive training modules lead to specific cognitive changes among patients diagnosed with schizophrenia? A single module effectiveness pilot study

Background and objectives: This study aimed to assess specific changes in cognitive biases and the efficacy of two individual metacognitive training (MCT) modules which target the jumping to conclusions bias and theory of mind deficits among people diagnosed with schizophrenia spectrum disorders.Methods: Thirty-one patients were randomly allocated to three groups: jumping to conclusions, theory of mind, and a control group. Paranoid ideation, jumping to conclusions, and theory of mind were assessed pre- and post-treatment.Results: There were no significant changes in paranoid ideation pre- and post-intervention in any group. There was a tendency towards a decrease in the jumping to conclusions bias in the corresponding group in comparison to the other two groups. There was a significant change in the theory of mind deficit in the corresponding group in comparison to the jumping to conclusions group, but not the control group.Conclusions: Our study tentatively suggests that a single module of MCT training based on theory of mind and jumping to conclusions may affect specific cognitive biases.
