Central Executive and Default Mode Networks: An Appraisal of Executive Function and Social Skill Brain-Behavior Correlates in Youth with Autism Spectrum Disorder / Jessica BLUME in Journal of Autism and Developmental Disorders, 54-5 (May 2024)

DHANASEKARA, Auteur ; Chanaka N. KAHATHUDUWA, Auteur ; Ann M. MASTERGEORGE, Auteur Article en page(s) : p.1882-1896 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Atypical connectivity patterns have been observed for individuals with autism spectrum disorders (ASD), particularly across the triple-network model. The current study investigated brain-behavior relationships in the context of social skills and executive function profiles for ASD youth. We calculated connectivity measures from diffusion tensor imaging using Bayesian estimation and probabilistic tractography. We replicated prior structural equation modeling of behavioral measures with total default mode network (DMN) connectivity to include comparisons with central executive network (CEN) connectivity and CEN-DMN connectivity. Increased within-CEN connectivity was related to metacognitive strengths. Our findings indicate behavior regulation difficulties in youth with ASD may be attributable to impaired connectivity between the CEN and DMN and social skill difficulties may be exacerbated by impaired within-DMN connectivity.

Eye-Tracking in Infants and Young Children at Risk for Autism Spectrum Disorder: A Systematic Review of Visual Stimuli in Experimental Paradigms / A. M. MASTERGEORGE in Journal of Autism and Developmental Disorders, 51-8 (August 2021)

Clear definitions and standardization of research protocols to document the utility and feasibility of these methods are warranted. This systematic review provides an account of stimuli dimensions and experimental paradigms used in eye-tracking research for young children at risk for ASD published from 2005 through 2019. This review identifies variability in eye-tracking protocols and heterogeneity of stimuli used for eye-tracking as factors that undermine the value of eye-tracking as an objective, reliable screening tool. We underscore the importance of sharing eye-tracking stimuli to enhance replicability of findings and more importantly the need to develop a bank of publicly available, validated stimuli.

Intrinsic Structural Connectivity of the Default Mode Network and Behavioral Correlates of Executive Function and Social Skills in Youth with Autism Spectrum Disorders / Jessica BLUME in Journal of Autism and Developmental Disorders, 53-5 (May 2023)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 53-5 (May 2023) . - p.1930-1941 Titre : Intrinsic Structural Connectivity of the Default Mode Network and Behavioral Correlates of Executive Function and Social Skills in Youth with Autism Spectrum Disorders Type de document : Texte imprimé et/ou numérique Auteurs : Jessica BLUME, Auteur ; Chanaka KAHATHUDUWA, Auteur ; Ann MASTERGEORGE, Auteur Article en page(s) : p.1930-1941 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Brain connectivity of individuals with autism spectrum disorders (ASD) is heterogenous, as are the behavioral manifestations. The current study investigated brain-behavior relationships in the context of social skills and executive function profiles with data from the Autism Brain Imaging Database Exchange II. We calculated connectivity measures from diffusion tensor imaging using Bayesian estimation and probabilistic tractography. Subsequently, we performed structural equation modeling by regressing three latent factors, yielded from an exploratory factor analysis, onto total default mode network (DMN) connectivity. Both social regulation processing and self-directed cognitive processing factors moderately, negatively correlated with total DMN connectivity. Our findings indicate social regulation processing difficulties in youth with ASD may be attributable to impaired connectivity between the anterior and posterior DMN.

Language Growth in Young Children with Autism: Interactions Between Language Production and Social Communication / Jessica BLUME in Journal of Autism and Developmental Disorders, 51-2 (February 2021)

MASTERGEORGE, Auteur Article en page(s) : p.644-665 Langues : Anglais (eng) Mots-clés : Autism  Gesture  Language  Social communication Index. décimale : PER Périodiques Résumé : Young children with autism spectrum disorder (ASD) present with a broad range of spoken language abilities, as well as delays in precursor skills such as gesture production and joint attention skills. While standardized assessments describe language strengths, the Communication and Symbolic Behavior Scales (CSBS-DP) is a particularly robust measure as it additionally characterizes precise aspects of social communication. This study provides a unique contribution by assessing the interactional effects of CSBS-DP Social Composite performance with early language samples on later language outcomes. Our results indicate that multiple social communication elements significantly interact with early spoken language to predict later language. Our findings also highlight the transactional relationship between early spoken vocabulary and social communication skills that bolster language development growth.

Predicting Language in Children with ASD Using Spontaneous Language Samples and Standardized Measures / Rebecca P. THOMAS in Journal of Autism and Developmental Disorders, 53-10 (October 2023)

MASTERGEORGE, Auteur ; Letitia NAIGLES, Auteur Article en page(s) : p.3916-3931 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : This longitudinal study examined the degree to which standardized measures of language and natural language samples predicted later language usage in a heterogeneous sample of children with autism spectrum disorder (ASD), and how this relationship is impacted by ASD severity and interventions. Participants with a diagnosis of ASD (N=54, 41 males) completed standardized assessments of language and social functioning; natural language samples were transcribed from play-based interactions. Findings indicated that standardized language measures, natural language measures, and ADOS severity were each unique predictors of later lexical use. Intervention types also appeared to impact later language; in particular, participation in mainstream inclusion accounted for significant amounts of variance in children?s mean length of utterance at T3.
