Social complexity and the early social environment affect visual social attention to faces / T. TSANG in Autism Research, 12-3 (March 2019)  

Public ISBD [article]  inAutism Research > 12-3 (March 2019) . - p.445-457 Titre : Social complexity and the early social environment affect visual social attention to faces Type de document : Texte imprimé et/ou numérique Auteurs : T. TSANG, Auteur ; S. JOHNSON, Auteur ; S. JESTE, Auteur ; Mirella DAPRETTO, Auteur Article en page(s) : p.445-457 Langues : Anglais (eng) Mots-clés : autism risk  broad autism phenotype  infancy  social development  visual social attention Index. décimale : PER Périodiques Résumé : Diminished attention to socially relevant information appears to be an early emerging risk factor associated with autism spectrum disorders (ASD). However, inconsistencies across studies suggest that atypicalities in visual social attention in infants at high-risk for ASD during the first postnatal year may be subtle and more apparent under certain contexts. Here we explore factors that may moderate developmental trajectories in attention to faces, including the social complexity of the dynamic visual stimuli used to measure visual social attention and the early social environment of the infant as indexed by parental affectedness of ASD-related traits. Across infants at both high (HR) and low risk for ASD, attention to faces increased during the first postnatal year, with overall greater attention being allocated to schematic faces in the simpler video stimulus. Moreover, greater parental affectedness of ASD-related traits was associated with reduced developmental gains in attention to faces. For HR infants, greater attention to faces was positively associated with social communicative competence, including better joint attention skills and lower social impairments. Altogether, our findings highlight the importance of considering developmental level when selecting stimuli to longitudinally examine visual social attention, and the clinical relevance of including measures of infant's social environment in understanding early markers of ASD risk. Autism Res 2019, 12: 445-457 (c) 2019 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: Attention to faces is an important means for infants to learn about the social world. The complexity of the social scene and an infant's early social environment both affect the amount of time infants at high- and low-risk for ASD look at faces during the first postnatal year. For infants at high-risk for ASD, greater attention to faces was associated with better social skills. Understanding an infant's social environment may have a positive impact on social communicative development.

Theory of Mind Indexes the Broader Autism Phenotype in Siblings of Children with Autism at School Age / T. TSANG in Autism Research and Treatment, 2016 (2016)  

Public ISBD [article]  inAutism Research and Treatment > 2016 (2016) Titre : Theory of Mind Indexes the Broader Autism Phenotype in Siblings of Children with Autism at School Age Type de document : Texte imprimé et/ou numérique Auteurs : T. TSANG, Auteur ; K. GILLESPIE-LYNCH, Auteur ; T. HUTMAN, Auteur Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Subclinical variants of the social-communicative challenges and rigidity that define autism spectrum disorder (ASD) are known as the broader autism phenotype (BAP). The BAP has been conceptualized categorically (as specific to a subset of relatives of individuals with ASD) and dimensionally (as continuously distributed within the general population). The current study examined the compatibility of these two approaches by assessing associations among autism symptoms and social-communicative skills in young school-age children with ASD, children who have a sibling with ASD, and children without a sibling with ASD. Autism symptoms were associated with reduced Theory of Mind (ToM), adaptive skills, cognitive empathy, and language skills across the full sample. Reduced ToM was a core aspect of the BAP in the current sample regardless of whether the BAP was defined categorically (in terms of siblings of children with ASD who exhibited atypical developmental) or dimensionally (in terms of associations with autism symptoms across the entire sample). Early language skills predicted school-age ToM. Findings support the compatibility of categorical and dimensional approaches to the BAP, highlight reduced ToM as a core aspect of the school-age BAP, and suggest that narrative-based approaches to promoting ToM may be beneficial for siblings of children with ASD.

Visual Traces of Language Acquisition in Toddlers with Autism Spectrum Disorder During the Second Year of Life / Serene HABAYEB in Journal of Autism and Developmental Disorders, 51-7 (July 2021)

To explore the adaptive implications of this engagement, we collected eye-tracking measures on cross-sectional samples of 10-25-month-old typically developing toddlers (TD;N?=?28) and those with autism spectrum disorder (ASD;N?=?54). Concurrent language assessments were conducted and relationships between visual engagement and expressive and receptive language were analyzed between groups, and within ASD subgroups. TD and ASD toddlers exhibited greater mouth- than eye-looking, with TD exhibiting higher levels of mouth-looking than ASD. Mouth-looking was positively associated with expressive language in TD toddlers, and in ASD toddlers who had acquired first words. Mouth-looking was unrelated to expressive language in ASD toddlers who had not yet acquired first words.
