HYDE, Auteur Article en page(s) : p.51-61 Langues : Anglais (eng) Mots-clés : Autism  Auditory  Motor  Rhythm  Synchronization  Development Index. décimale : PER Périodiques Résumé : Autism spectrum disorder (ASD) is characterized by difficulties in social and communication skills as well as atypical sensory perception and motor skills. Sensorimotor abilities such as auditory-motor integration are essential for social interaction and communication. The goal of this research was to investigate the development of auditory-motor rhythm synchronization for the first time in ASD versus typically-developing (TD) children. Methods Participants were 31 boys with ASD and 23 TD boys that were matched in age and IQ. Participants were tested on an auditory-motor rhythm synchronization task in which they tapped in synchrony with rhythms of varying metrical complexity. Results Both children with ASD and TD performed similarly on this task and both groups performed better with age. This work demonstrates that non-verbal rhythm synchronization is intact in ASD over the course of childhood development. This research serves to better understand sensorimotor interactions in ASD and to better define sensory phenotypes in ASD.

Effects of Age and Attention on Auditory Global–Local Processing in Children with Autism Spectrum Disorder / Nicholas E. V. FOSTER in Journal of Autism and Developmental Disorders, 46-4 (April 2016)

HYDE, Auteur Article en page(s) : p.1415-1428 Langues : Anglais (eng) Mots-clés : Autism  Auditory  Development  Attention Index. décimale : PER Périodiques Résumé : In vision, typically-developing (TD) individuals perceive “global” (whole) before “local” (detailed) features, whereas individuals with autism spectrum disorder (ASD) exhibit a local bias. However, auditory global–local distinctions are less clear in ASD, particularly in terms of age and attention effects. To these aims, here ASD and TD children judged local and global pitch structure in nine-tone melodies. Both groups showed a similar global precedence effect, but ASD children were less sensitive to global interference than TD children at younger ages. There was no effect of attention task. These findings provide novel evidence of developmental differences in auditory perception and may help to refine sensory phenotypes in ASD.

Epidemiology of Autism Spectrum Disorders / Lisa R. FRENCH

Public ISBD in The Neuroscience of Autism Spectrum Disorders / Joseph D. BUXBAUM Titre : Epidemiology of Autism Spectrum Disorders Type de document : Texte imprimé et/ou numérique Auteurs : Lisa R. FRENCH, Auteur ; Armando BERTONE, Auteur ; Krista L. HYDE, Auteur ; Eric FOMBONNE, Auteur Année de publication : 2013 Importance : p.3-24 Langues : Anglais (eng) Index. décimale : SCI-D SCI-D - Neurosciences Résumé : In this chapter, we discuss methodological factors which impact the estimation of prevalence of autism spectrum disorders (ASD), and how current trends in prevalence change are being interpreted. Our systematic literature review results in prevalence estimates ranging from 0.063% to 2.6% for ASD, with the best current estimate of prevalence being approximately (74/10,000). Males are affected four to five times more often than females. In addition, a smaller proportion of children diagnosed with an autistic disorder (~32%) compared to that of all ASD children combined (~53%) have normal cognitive functioning. Rate trends analyses confirm an increase in ASD prevalence, and that the possibility of a true increase in incidence should not be ruled out. Explanations for an increase of ASD within and across populations are considered. However, increasing trends in prevalence rates cannot be directly attributed to an increase in the incidence of ASD, due to multiple confounding factors.

Evidence for intact melodic and rhythmic perception in children with Autism Spectrum Disorder / Kevin JAMEY in Research in Autism Spectrum Disorders, 64 (August 2019)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 64 (August 2019) . - p.1-12 Titre : Evidence for intact melodic and rhythmic perception in children with Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Kevin JAMEY, Auteur ; Nicholas E. V. FOSTER, Auteur ; Megha SHARDA, Auteur ; Carola TUERK, Auteur ; Aparna NADIG, Auteur ; Krista L. HYDE, Auteur Article en page(s) : p.1-12 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder  Auditory  Music  Perception  Cognition  Development Index. décimale : PER Périodiques Résumé : Background Autism spectrum disorder (ASD) is a complex neurodevelopmental condition characterized by socio-communicative difficulties and restricted patterns of behavior. Despite these challenges, some individuals with ASD have preserved or even enhanced sensory skills, for example in the case of music. As such, music provides a key way to study sensory processing and individual differences in ASD. However, current studies of music perception in ASD have mixed results. Methods This study sought to examine music perception in terms of melodic pitch, rhythm, and memory in school-age children with ASD compared to typically-developing (TD) children. Music perception was investigated as a function of verbal and non-verbal IQ, age, and ASD social symptom severity. Results Children with ASD performed similar to TD children on melodic pitch perception, rhythm perception and melodic memory. Melodic pitch perception in particular was strongly associated with non-verbal cognitive abilities in the ASD group. Similar effects of age on performance were observed in ASD and TD; in particular, rhythm discrimination increased with age in both groups. Music perception in ASD was not associated with ASD social symptom severity. Discussion These findings provide further evidence for intact melodic and rhythmic perception in children with ASD. In addition, music perception abilities were related to non-verbal cognitive ability and age in ASD, and not with ASD social symptom severity. This research provides a better understanding of individual differences in auditory processing, helps to better define phenotypes in ASD, and can guide future studies on the effects of music therapy in ASD.

Is there a bit of autism in all of us? Autism spectrum traits are related to cortical thickness differences in both autism and typical development / Line GEBAUER in Research in Autism Spectrum Disorders, 13-14 (May 2015)

However, these traits are highly variable across individuals with ASD and are also present in the typically developing population. Brain structural correlates of ASD are also heterogeneous. Recent findings have indicated that ASD traits as measured by the autism quotient (AQ) are reflected in white matter structural differences in a continuous way across both typically-developed and ASD individuals. Here, we tested for the first time, how ASD traits are related to gray matter structural differences (and particularly cortical thickness) in both ASD and typically developing adults. The present results show that ASD traits are primarily correlated with reductions in cortical thickness in a continuous fashion across ASD and typically developing adults in social brain areas and the default mode network including the orbitofrontal cortex, postcentral gyrus, and lingual gyrus. These findings provide new evidence that ASD traits are primarily reflected in neural structure that exists along a continuum extending into the typically developing population.
