Executive function predicts the development of play skills for verbal preschoolers with autism spectrum disorders / Susan FAJA in Autism Research, 9-12 (December 2016)  

Public ISBD [article]  inAutism Research > 9-12 (December 2016) . - p.1274-1284 Titre : Executive function predicts the development of play skills for verbal preschoolers with autism spectrum disorders Type de document : Texte imprimé et/ou numérique Auteurs : Susan FAJA, Auteur ; Geraldine DAWSON, Auteur ; Katherine SULLIVAN, Auteur ; Andrew N. MELTZOFF, Auteur ; Annette ESTES, Auteur ; Raphael BERNIER, Auteur Article en page(s) : p.1274-1284 Langues : Anglais (eng) Mots-clés : autism  executive function  inhibition  spatial working memory  play  language Index. décimale : PER Périodiques Résumé : Executive function and play skills develop in early childhood and are linked to cognitive and language ability. The present study examined these abilities longitudinally in two groups with autism spectrum disorder—a group with higher initial language (n?=?30) and a group with lower initial language ability (n?=?36). Among the lower language group, concurrent nonverbal cognitive ability contributed most to individual differences in executive function and play skills. For the higher language group, executive function during preschool significantly predicted play ability at age 6 over and above intelligence, but early play did not predict later executive function. These results suggested that factors related to the development of play and executive function differ for subgroups of children with different language abilities and that early executive function skills may be critical in order for verbal children with autism to develop play.

Executive Function Skills Are Linked to Restricted and Repetitive Behaviors: Three Correlational Meta Analyses / R. K. IVERSEN in Autism Research, 14-6 (June 2021)  

Public ISBD [article]  inAutism Research > 14-6 (June 2021) . - p.1163-1185 Titre : Executive Function Skills Are Linked to Restricted and Repetitive Behaviors: Three Correlational Meta Analyses Type de document : Texte imprimé et/ou numérique Auteurs : R. K. IVERSEN, Auteur ; C. LEWIS, Auteur Article en page(s) : p.1163-1185 Langues : Anglais (eng) Mots-clés : Autism Spectrum Disorder  Autistic Disorder  Child  Cognition  Executive Function  Humans  Meta-Analysis as Topic  Parents  autism  executive function  meta-analysis  restricted and repetitive behaviors  systematic review Index. décimale : PER Périodiques Résumé : There is a consensus on the centrality of restricted and repetitive behaviors (RRBs) in the diagnosis of Autism Spectrum Disorder (ASD), yet the origins of these behaviors are still debated. We reconsider whether executive function (EF) accounts of RRBs should be revisited. EF deficits and high levels of RRBs are often pronounced in individuals with ASD and are also prevalent in young typically developing children. Despite this, the evidence is mixed, and there has been no systematic attempt to evaluate the relationship across studies and between task batteries. We examine recent evidence, and in three highly powered random-effects analyses (N =?2964), examine the strength of the association between RRB levels and performance on set shifting, inhibitory control, and parental-report based EF batteries. The analyses confirm significant associations between high levels of the behaviors and poor EF skills. Moreover, the associations remained stable across typical development and in individuals with ASD and across different types of EF measures. These meta-analyses consolidate recent evidence identifying that cognitive mechanisms correlate with high RRBs that are seen in individuals with ASD, as well as in typical development. We propose that the EF account may be critical for guiding future interventions in ASD research. LAY SUMMARY: Restricted and repetitive behaviors (RRBs) are diagnostic criteria for Autism yet also common in typical development, and if they persist over time some can have a negative impact on learning and social acceptance. The present meta-analyses found that high levels of RRBs related to poor performance on set-shifting and inhibitory control tasks, as well as high ratings on parental report scales. Future studies should create interventions that aim to improve these skills as they may help manage challenging RRBs.

Executive function and functional and structural brain differences in middle-age adults with autism spectrum disorder / B. Blair BRADEN in Autism Research, 10-12 (December 2017)  

Public ISBD [article]  inAutism Research > 10-12 (December 2017) . - p.1945-1959 Titre : Executive function and functional and structural brain differences in middle-age adults with autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : B.

BAXTER, Auteur Article en page(s) : p.1945-1959 Langues : Anglais (eng) Mots-clés : autism  aging  executive function  magnetic resonance imaging (MRI)  functional connectivity  diffusion tensor imaging  hippocampus  working memory Index. décimale : PER Périodiques Résumé : There is a rapidly growing group of aging adults with autism spectrum disorder (ASD) who may have unique needs, yet cognitive and brain function in older adults with ASD is understudied. We combined functional and structural neuroimaging and neuropsychological tests to examine differences between middle-aged men with ASD and matched neurotypical (NT) men. Participants (ASD, n?=?16; NT, n?=?17) aged 40–64 years were well-matched according to age, IQ (range: 83–131), and education (range: 9–20 years). Middle-age adults with ASD made more errors on an executive function task (Wisconsin Card Sorting Test) but performed similarly to NT adults on tests of delayed verbal memory (Rey Auditory Verbal Learning Test) and local visual search (Embedded Figures Task). Independent component analysis of a functional MRI working memory task (n-back) completed by most participants (ASD?=?14, NT?=?17) showed decreased engagement of a cortico-striatal-thalamic-cortical neural network in older adults with ASD. Structurally, older adults with ASD had reduced bilateral hippocampal volumes, as measured by FreeSurfer. Findings expand our understanding of ASD as a lifelong condition with persistent cognitive and functional and structural brain differences evident at middle-age. Autism Res 2017, 10: 1945–1959. © 2017 International Society for Autism Research, Wiley Periodicals, Inc. Lay Summary We compared cognitive abilities and brain measures between 16 middle-age men with high-functioning autism spectrum disorder (ASD) and 17 typical middle-age men to better understand how aging affects an older group of adults with ASD. Men with ASD made more errors on a test involving flexible thinking, had less activity in a flexible thinking brain network, and had smaller volume of a brain structure related to memory than typical men. We will follow these older adults over time to determine if aging changes are greater for individuals with ASD.

Executive function as a mediator in the link between attention-deficit/hyperactivity disorder and social problems / Wan-Ling TSENG in Journal of Child Psychology and Psychiatry, 54-9 (September 2013)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 54-9 (September 2013) . - p.996-1004 Titre : Executive function as a mediator in the link between attention-deficit/hyperactivity disorder and social problems Type de document : Texte imprimé et/ou numérique Auteurs : Wan-Ling TSENG, Auteur ; Susan Shur-Fen GAU, Auteur Article en page(s) : p.996-1004 Langues : Anglais (eng) Mots-clés : ADHD  executive function  social problems  mediator Index. décimale : PER Périodiques Résumé : Background Cognitive processes and mechanisms underlying the strong link between attention-deficit/hyperactivity disorder (ADHD) and social problems remain unclear. Limited knowledge also exists regarding a subgroup of youth with ADHD who do not have social problems. This study investigated the extent to which executive function (EF) mediated the association between ADHD and social problems and compared ADHD symptoms, comorbidities, and EF among ADHD youth with and without social problems and controls. Methods The sample consisted of 279 youth with ADHD and 173 controls without ADHD (11–17 years of age) in Taiwan. Among youth with ADHD, two subgroups were further identified: 70 ADHD youth with social problems and 31 ADHD youth without social problems. EF was assessed with four subtests from the Cambridge Neuropsychological Test Automated Battery (Spatial span, Spatial working memory, Intra-dimensional/extra-dimensional shifts, Stockings of Cambridge). Social problems were assessed by mother and child reports. Results Executive function measures in working memory and planning mediated the effect of ADHD on social problems, independent of age, gender, and IQ. The two ADHD groups with and without social problems did not differ in ADHD severity or comorbidities; however, ADHD youth without social problems performed better on certain measures of EF such as working memory, planning, and response inhibition. Conclusions These findings suggest that deficits in some aspects of EF may account for social problems often experienced by youth with ADHD.

Executive Function: Cognition and Behaviour in Adults with Autism Spectrum Disorders (ASD) / K. JOHNSTON in Journal of Autism and Developmental Disorders, 49-10 (October 2019)

Possible confounds include EF domain assessed and co-occurring neurodevelopmental diagnoses. EF task performance across multiple domains and everyday function of autistic adults (n = 110) was significantly different to age- and IQ-matched controls (n = 31). Although significantly more likely to fall into the clinically impaired range, 35.8% of the ASD group showed no impairment on EF measures. Factor analysis revealed a single unifying EF construct rather than a selective pattern of impairment. Dysexecutive behaviours were frequently reported in the ASD group, unrelated to Autism symptoms, EF task performance or co-occurring conditions. This study suggests autistic adults can experience clinically significant executive function difficulties and co-occuring dysexecutive behaviours that are disabling in everyday life.
