Acoustic differences in the imitation of prosodic patterns in children with autism spectrum disorders / Joshua John DIEHL in Research in Autism Spectrum Disorders, 6-1 (January-March 2012)
[article]
Titre : Acoustic differences in the imitation of prosodic patterns in children with autism spectrum disorders Type de document : Texte imprimé et/ou numérique Auteurs : Joshua John DIEHL, Auteur ; Rhea PAUL, Auteur Année de publication : 2012 Article en page(s) : p.123-134 Langues : Anglais (eng) Mots-clés : Autism Imitation Prosody Acoustic Communication Pragmatics Index. décimale : PER Périodiques Résumé : In research, it has been difficult to characterize the prosodic production differences that have been observed clinically in autism spectrum disorders (ASD). Moreover, the nature of these differences has been particularly hard to identify. This study examined one possible contributor to these perceived differences: motor planning. We examined the ability of children and adolescents with ASD to imitate prosodic patterns in comparison to a group with learning disabilities (LD) and a typically developing (TD) comparison group. Overall, we found that both the ASD and LD groups were significantly worse at perceiving and imitating prosodic patterns than the TD comparison group. Similar to previous studies using non-imitative speech, participants with ASD showed a significantly longer duration of utterances than the two comparison groups when attempting to imitate an intonation pattern. The implications of differences in duration of utterances are discussed. This study also highlights the importance of using clinical comparison groups in studies of language performance in individuals with ASD.

PATEL, Auteur ; Kritika NAYAR, Auteur ; Gary E. MARTIN, Auteur ; Kathryn FRANICH, Auteur ; Stephanie CRAWFORD, Auteur ; Joshua J. DIEHL, Auteur ; Molly LOSH, Auteur Article en page(s) : p.3032-3045 Langues : Anglais (eng) Mots-clés : Acoustic Autism spectrum disorder Broad autism phenotype Prosody Index. décimale : PER Périodiques Résumé : This study examined prosody through characterization of acoustic properties of the speech of individuals with ASD and their parents, during narration. A subset of utterances were low-pass filtered and rated for differences in intonation, speech rate, and rhythm. Listener ratings were minimally related to acoustic measures, underscoring the complexity of atypical prosody in ASD. Acoustic analyses revealed greater utterance-final fundamental frequency excursion size and slower speech rate in the ASD group. Slower speech rate was also evident in the ASD parent group, particularly parents with the broad autism phenotype. Overlapping prosodic differences in ASD and ASD Parent groups suggest that prosodic differences may constitute an important phenotype contributing to ASD features and index genetic liability to ASD among first-degree relatives.
