Atypical Cry Acoustics in 6-Month-Old Infants at Risk for Autism Spectrum Disorder / Stephen J. SHEINKOPF in Autism Research, 5-5 (October 2012)
[article]
Titre : Atypical Cry Acoustics in 6-Month-Old Infants at Risk for Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Stephen J. SHEINKOPF, Auteur ; Jana M. IVERSON, Auteur ; Melissa L. RINALDI, Auteur ; Barry M. LESTER, Auteur Article en page(s) : p.331-339 Langues : Anglais (eng) Mots-clés : autism infancy cry vocalizations acoustic analysis Index. décimale : PER Périodiques Résumé : This study examined differences in acoustic characteristics of infant cries in a sample of babies at risk for autism and a low-risk comparison group. Cry samples derived from vocal recordings of 6-month-old infants at risk for autism spectrum disorder (ASD; n=21) and low-risk infants (n=18) were subjected to acoustic analyses using analysis software designed for this purpose. Cries were categorized as either pain-related or non-pain-related based on videotape coding. At-risk infants produced pain-related cries with higher and more variable fundamental frequency (F 0) than low-risk infants. At-risk infants later classified with ASD at 36 months had among the highest F 0 values for both types of cries and produced cries that were more poorly phonated than those of nonautistic infants, reflecting cries that were less likely to be produced in a voiced mode. These results provide preliminary evidence that disruptions in cry acoustics may be part of an atypical vocal signature of autism in early life.
