Social and non-social sensory responsivity in toddlers at high-risk for autism spectrum disorder / J. GUNDERSON in Autism Research, 14-10 (October 2021)
[article]
Titre : Social and non-social sensory responsivity in toddlers at high-risk for autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : J. GUNDERSON, Auteur ; E. WORTHLEY, Auteur ; R. GRZADZINSKI, Auteur ; C. BURROWS, Auteur ; A. ESTES, Auteur ; Lonnie ZWAIGENBAUM, Auteur ; Kelly N. BOTTERON, Auteur ; Stephen R. DAGER, Auteur ; Heather C. HAZLETT, Auteur ; R. SCHULTZ, Auteur ; J. PIVEN, Auteur ; J. WOLFF, Auteur Article en page(s) : p.2143-2155 Langues : Anglais (eng) Mots-clés : Autism Spectrum Disorder Child, Preschool Female Humans Infant Male Surveys and Questionnaires context environment sensory functioning sensory responsivity social Index. décimale : PER Périodiques Résumé : Empirical evidence concerning sensory responsivity in young children who later develop autism spectrum disorder (ASD) remains relatively limited. It is unclear whether specific patterns or aspects of sensory responsivity underlay the emergence of the disorder. The goals of this study were to (a) examine whether social versus non-social context impacted the expression of sensory responsivity in infants at high risk for ASD, and (b) examine if sensory responsivity in social or non-social contexts was associated with severity of ASD symptoms. The Sensory Experiences Questionnaire 2.1 was collected for 338 infants (131 females, 207 males) at high-risk for ASD at 12 and/or 24?months of age. High-risk toddlers meeting diagnostic criteria for ASD (n =?75) showed elevated sensory responsivity in both social and non-social contexts at 12?months of age and differences widened over the second year of life. Individuals with ASD demonstrate higher responsivity in both contexts suggestive of generalized atypical sensory responsivity in ASD. LAY SUMMARY: Behaviors such as avoiding or noticing sensory input (e.g., sounds, touches) are often different in individuals with autism spectrum disorder (ASD) than those without. The reason for this is widely unknown. The findings from this study show that in toddlers, sensory responsivity increased in both social and non-social situations. Therefore, the setting of sensory input does not explain these differences.

Titre : Visual attention to faces in children with autism spectrum disorder: are there sex differences? Type de document : Texte imprimé et/ou numérique Auteurs : C. HARROP, Auteur ; D. JONES, Auteur ; S. ZHENG, Auteur ; Sallie W. NOWELL, Auteur ; R. SCHULTZ, Auteur ; Julia PARISH-MORRIS, Auteur Article en page(s) : 28 p. Langues : Anglais (eng) Mots-clés : Autism spectrum disorder Eye gaze Sex differences Social attention Social cognition Index. décimale : PER Périodiques Résumé : Background: The male bias in autism spectrum disorder (ASD) diagnoses is well documented. As a result, less is known about the female ASD phenotype. Recent research suggests that conclusions drawn from predominantly male samples may not accurately capture female behavior. In this study, we explore potential sex differences in attention to social stimuli, which is generally reported to be diminished in ASD. Population-based sex differences in attention to faces have been reported, such that typically developing (TD) females attend more to social stimuli (including faces) from infancy through adulthood than TD males. It is yet unknown whether population-based sex differences in the face domain are preserved in ASD. Methods: A dynamic, naturalistic infrared eye-tracking paradigm measured attention to social stimuli (faces) in 74 school-aged males and females with ASD (male N = 23; female N = 19) and without ASD (male N = 16; female N = 16). Two kinds of video stimuli were presented that varied in social content: rich social scenes (dyadic play between two children) and lean social scenes (parallel play by two children). Results: Results revealed a significant 3-way interaction between sex, diagnosis, and condition after controlling for chronological and mental age. ASD females attended more to faces than ASD males in the socially lean condition. This effect was not found in the typically developing (TD) group. ASD males attended less to faces regardless of social context; however, ASD females only attended significantly less to faces compared to TD females in the socially rich condition. TD males and ASD females did not differ in their attention to faces in either condition. Conclusions: This study has implications for how the field understands core social deficits in children with ASD, which should ideally be benchmarked against same-sex peers (male and female). Social attention in ASD females fell on a continuum-greater than their ASD male peers, but not as great as TD females. Overall, their social attention mirrored that of TD males. Improved understanding of the female social phenotype in ASD will enhance early screening and diagnostic efforts and will guide the development of sex-sensitive experimental paradigms and social interventions.
