Same or different? Theory of mind among children with and without disabilities

Theory of Mind: A Brief Review of Candidate Genes

Deficits in theory of mind (ToM), known as the ability to understand the other's mind, have been associated with several psychopathological outcomes. The present systematic review aims to summarize the results of genetic studies that investigated gene polymorphisms associated with mentalization performance tasks in children and adults. The systematic review was carried out following PRISMA guidelines, and the literature search was conducted in PubMed and EBSCOhost using the following keywords: 'theory of mind, mentalizing, mindreading' and 'gene, genetic basis'. Nineteen studies met the eligibility criteria for inclusion. Most of the literature focused on the role of DRD4, DAT1, OXTR, OXT, COMT, ZNF804A, AVP, AVPR, SCL6A4, EFHC2, MAO-A, and the family of GTF2I genes in influencing ToM. However, controversial results emerged in sustaining the link between specific genetic polymorphisms and mentalization abilities in children and adults. Available data show heterogeneous outcomes, with studies reporting an association between the same family genes in subjects of the same age and other studies reporting no correlation. This does not allow us to draw any solid conclusions but paves the way for exploring genes involved in ToM tasks.

Longitudinal relations between theory of mind and academic achievement among deaf and hard-of-hearing school-aged children

This 2-year longitudinal study investigated the bidirectional relations between the development of theory of mind (ToM) and academic competences in a sample of 270 deaf and hard-of-hearing (DHH) children (Mage at Wave 1 = 7.52 years, SD = 0.99; 58.5% boys and 41.5% girls). Across three waves (10 months apart), children were assessed for their ToM abilities, using the ToM scale and a second-order false belief task, as well as for their language and mathematics skills. Cross-lagged correlational analysis revealed significant bidirectional associations between ToM and academic achievement (language and mathematics). That is, ToM predicted academic achievement with similar strength as ToM development itself was predicted by academic achievement. Our results highlight the bidirectional nature of the association between ToM and academic achievement, and they show that ToM development plays a crucial role in DHH children's school functioning.

Virtual reality and augmented reality as strategies for teaching social skills to individuals with intellectual disability: A systematic review

Virtual reality (VR) and augmented reality (AR) programs have proliferated significantly in recent years and they are finding their way into different educational and therapeutic purposes. This systematic review aims at analyzing the virtual reality and augmented reality programs designed to promote the development of social skills in individuals with intellectual disability. Searches were carried out in the Scopus, Science Direct, Springer and Web of Science databases in the period from 2005 to 2020. A total of six articles met the inclusion criteria. A descriptive data analysis was performed. The results show that the clinical profile of the individuals who participated in the interventions is diverse. It can be concluded that there is some scientific evidence that points to the usefulness of VR and AR in the development of intervention programs to improve the social skills of individuals diagnosed with developmental deficits. However, it is necessary to acknowledge methodological limitations such as the lack of control groups, follow-up measures and of generalization of the results.

Specific Language Impairment, Autism Spectrum Disorders and Social (Pragmatic) Communication Disorders: Is There Overlap in Language Deficits? A Review

Analysing language characteristics and understanding their dynamics is the key for a successful intervention by speech and language therapists (SLT). Thus, this review aims to investigate a possible overlap in language development shared by autism spectrum disorders (ASD), specific language impairment (SLI) and social (pragmatic) communication disorder (SPCD). The sources of this work were the PubMed, PsycInfo and SciELO databases, as well as the Scientific Open Access Repositories of Portugal. The final selection included 18 studies, focused on several linguistic areas. Results suggest that when individuals are matched according to some language or cognitive skills, they will also show similar characteristics in other language domains. Future work should be done based on spontaneous speech.

Just listen to your mind: Consequences of theory of mind development for deaf or hard-of-hearing children

BACKGROUND

Previous research reveals relations between theory of mind (ToM) and cognitive outcomes, but mostly among typically developing children.

AIM

To study these relations in children with developmental difficulties, this longitudinal study investigated the cognitive consequences of ToM in deaf or hard-of-hearing (DHH) children.

METHODS AND PROCEDURES

One hundred and thirty-four (X = 9.2 years) participants were assessed in three waves, i.e., one wave every ten months. The participants completed the ToM scale, language and literacy skills (LLS) tests, the academic self-concept in language (ASC-L) questionnaire, and the sensitivity to criticism measure.

OUTCOMES AND RESULTS

The results revealed that high levels of children's ToM ability predicted higher levels of LLS 20 months later. Mediators of this association were sensitivity to criticism and ASC-L. Controlling for LLS at T1, ASC-L at T2 mediated the relations between ToM and LLS at T3. Moreover, sensitivity to criticism predicted ASC-L, and sensitivity to criticism and ASC-L mediated the relation between ToM and LLS at T3. That is, children who were sensitive to criticism and held positive views of their academic self were also better skilled in ToM and in LLS.

CONCLUSIONS AND IMPLICATIONS

Our results can help improve the education of DHH students.

The relationship between theory of mind and sluggish cognitive tempo in school-age children with attention deficit and hyperactivity disorder

Sluggish cognitive tempo (SCT) is considered as a cognitive-emotional style. Theory of mind (ToM) skills form the basis of human cognition and social behavior. The aim of this study is to contribute to SCT literature by examining the relationship between SCT and cognitive and affective ToM in school-age children with attention deficit and hyperactivity disorder (ADHD). Fifty school-age children with ADHD (43 boys and seven girls) and 40 typically developing children (34 boys and six girls) were assessed using Parent-rated Barkley Child Attention Scale and Child Behavior Checklist/6-18, cognitive (first- and second-order ToM) and affective ToM (Reading Mind in the Eyes Test and Unexpected Outcomes Test (UOT)) tests. Multiple linear regression analysis was performed to determine the variables that may predict SCT levels in children with ADHD. Attention deficit and hyperactivity disorder-inattention (Exp(B) = .334, p = .027), internalization (Exp(B) = .305, p = .006), and UOT scores (Exp(B) = .933, p = .015) significantly predicted SCT severity in children with ADHD. SCT severity was significantly associated with impaired cognitive ToM skills as measured by second-order ToM (Exp(B) = 1.933, p = .045). Our findings may indicate that affective ToM developing with age, and impaired cognitive ToM skills are associated with increasing SCT severity.

Advanced theory of mind in children with mild intellectual disability and deaf or hard of hearing children: A two-year longitudinal study in middle childhood

The present study investigates the development of advanced theory of mind (AToM) among typically developing (TD) children, children with mild intellectual disability (MID), and deaf or hard of hearing (DHH) children. The 2-year longitudinal study comprised three waves and included a large sample of children from Poland in middle childhood aged around 7.5-9.5 years (N = 779; M = 7.7, SD = 0.92 at wave 1). The analysis of children's understanding of second-order false belief and the Faux-Pas Recognition Test showed that TD children outperformed children with MID and DHH children on both measures. At 7.5 years, almost 60% of the TD children correctly solved the second-order false belief task; correct performance at 7.5 years in children with MID and DHH children was 27 and 38% respectively. Two years later, correct performance rose to 80% (TD children), 45% (children with MID), and 63% (DHH children). Despite these differences, the speed of AToM development did not differ across the groups. The development of faux-pas recognition followed a non-linear pattern, with TD children showing no further significant development after mid-elementary school. Our findings show differences in AToM development between TD children, children with MID, and DHH children, and they suggest that children's development of AToM may follow different developmental pathways, depending on the aspect of AToM under study.

Theory of mind goes to school: Does educational environment influence the development of theory of mind in middle childhood?

Previous research has shown that the development of theory of mind (ToM) depends on various individual and social factors, but very little research has examined the role of the natural educational environment in the development of ToM in middle childhood. In accordance with the importance of social factors in development, in this longitudinal study of 156 typically developing children, we investigated whether educational setting-classes containing children with disabilities (inclusive) or without such children (general education)-is associated with enhanced ToM development. ToM was measured with the ToM Scale, the Chocolate task and the Faux Pas Recognition Test. Analysis showed that ToM development was better among children educated in inclusive classes than among those educated in traditional classes. The results have implications for ToM development among children with and without disabilities as well as for educational practice.

Diagnóstico de autismo no século XXI: evolução dos domínios nas categorizações nosológicas

Resumo Os critérios que subsidiaram o diagnóstico do autismo passaram por diversas mudanças ao longo dos anos, acompanhando os pressupostos conceituais hegemônicos no período. O objetivo deste estudo é analisar a evolução do diagnóstico do autismo no século XXI, a partir dos domínios e subdomínios em que se baseiam as categorizações nosológicas. Adicionalmente, são sinalizados instrumentos auxiliares utilizados e algumas tecnologias diagnósticas em desenvolvimento, além de modelos conceituais que tratam do perfil neuropsicológico. Trata-se de pesquisa documental, tendo como referência os manuais diagnósticos existentes no período. Os domínios de interação social, comunicação e padrão restrito e repetitivo de comportamento foram mantidos nos diferentes manuais diagnósticos abordados. Os subdomínios de interação social e comunicação foram reduzidos, enquanto o padrão restrito e repetitivo teve consolidação no DSM-5. Compreender a evolução dos critérios diagnósticos tende a promover o desenvolvimento da clínica, potencializando a antecipação do diagnóstico e as intervenções necessárias para um melhor prognóstico.

Cognitive processes predicting advanced theory of mind in the broader autism phenotype

Little is known about executive functions (EFs) associated with advanced theory of mind (ToM) abilities. We aimed to determine if advanced ToM abilities were reduced in individuals with subclinical traits of autism spectrum disorder (ASD), known as the "Broader Autism Phenotype" (BAP), and identify the EFs that predicted unimpaired performance on an advanced ToM task, the faux pas test. We assessed 29 participants (13 males) with the BAP who were relatives of children with ASD. Thirteen participants showed reduced ability to understand a faux pas. A discriminant function analysis correctly classified 79% of cases as impaired or unimpaired, with high sensitivity (80%) and specificity (77%), which was best predicted by language-mediated EFs, including verbal generativity, working memory, cognitive inhibition, and flexibility. Autism Res 2020, 13: 921-934. © 2019 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: Little is known about the complex cognitive processes that enable accurate interpretation of another person's thoughts and emotions, known as "theory of mind." In relatives of individuals with autism, who had mild traits of autism themselves, approximately half had difficulty interpreting situations involving a social faux pas. Cognitive inhibition and flexibility, working memory, and verbal generativity were related to, and appeared to be protective for, unimpaired understanding of a faux pas.

Theory of mind development in school environment: A case of children with mild intellectual disability learning in inclusive and special education classrooms

BACKGROUND

This longitudinal study examines the extent to which a school classroom (inclusive vs. special education) is meaningful for theory of mind (ToM) development among children with mild intellectual disability.

MATERIALS AND METHODS

The participant group consisted of 166 primary school-aged children (M = 8.1, SD = 0.99), 79 of whom attended inclusive classrooms; the remaining 87 were in special education classrooms.

RESULTS

Although all children developed ToM over time, children's learning of ToM in inclusive classrooms was significantly greater than that seen in special classrooms. The difference remained significant after controlling for age. The present authors have compared children's individual and family characteristics, but there were almost no differences between groups.

CONCLUSIONS

The present authors discuss the results in the light of their importance for children's cognitive and social development. The implications for children's education are also considered.
