Individuals with autism spectrum disorder are impaired in absolute but not relative pitch and duration matching in speech and song imitation / L. WANG in Autism Research, 14-11 (November 2021)
[article]
Titre : Individuals with autism spectrum disorder are impaired in absolute but not relative pitch and duration matching in speech and song imitation Type de document : Texte imprimé et/ou numérique Auteurs : L. WANG, Auteur ; P. Q. PFORDRESHER, Auteur ; C. JIANG, Auteur ; F. LIU, Auteur Article en page(s) : p.2355-2372 Langues : Anglais (eng) Mots-clés : Adult Autism Spectrum Disorder/complications Child Humans Imitative Behavior Singing Speech Voice Asd duration pitch song speech vocal imitation Index. décimale : PER Périodiques Résumé : Individuals with autism spectrum disorder (ASD) often exhibit atypical imitation. However, few studies have identified clear quantitative characteristics of vocal imitation in ASD. This study investigated imitation of speech and song in English-speaking individuals with and without ASD and its modulation by age. Participants consisted of 25 autistic children and 19 autistic adults, who were compared to 25 children and 19 adults with typical development matched on age, gender, musical training, and cognitive abilities. The task required participants to imitate speech and song stimuli with varying pitch and duration patterns. Acoustic analyses of the imitation performance suggested that individuals with ASD were worse than controls on absolute pitch and duration matching for both speech and song imitation, although they performed as well as controls on relative pitch and duration matching. Furthermore, the two groups produced similar numbers of pitch contour, pitch interval-, and time errors. Across both groups, sung pitch was imitated more accurately than spoken pitch, whereas spoken duration was imitated more accurately than sung duration. Children imitated spoken pitch more accurately than adults when it came to speech stimuli, whereas age showed no significant relationship to song imitation. These results reveal a vocal imitation deficit across speech and music domains in ASD that is specific to absolute pitch and duration matching. This finding provides evidence for shared mechanisms between speech and song imitation, which involves independent implementation of relative versus absolute features. LAY SUMMARY: Individuals with autism spectrum disorder (ASD) often exhibit atypical imitation of actions and gestures. Characteristics of vocal imitation in ASD remain unclear. By comparing speech and song imitation, this study shows that individuals with ASD have a vocal imitative deficit that is specific to absolute pitch and duration matching, while performing as well as controls on relative pitch and duration matching, across speech and music domains.

MATTHEWS, Auteur ; Jessica LAFLIN, Auteur ; Beatriz C. ORR, Auteur ; Katrina WARRINER, Auteur ; Mary DECARLO, Auteur ; Christopher J. SMITH, Auteur Article en page(s) : p.2201-2207 Langues : Anglais (eng) Mots-clés : Adolescents Autism spectrum disorder Duration PEERS social skills intervention Index. décimale : PER Périodiques Résumé : Evidence supporting the effectiveness of the PEERS® social skills intervention for adolescents with autism spectrum disorder is relatively strong. Less is known about whether the duration of the program impacts participant outcomes. The current study compared outcomes of participants randomly assigned to participate in an accelerated version of PEERS that met twice weekly for 7 weeks (n?=?11) or the traditional PEERS program that met once weekly for 14 weeks (n?=?10). The accelerated PEERS group demonstrated improvements consistent with previous research on the program, and treatment response did not differ significantly between the accelerated PEERS and traditional PEERS groups. Together, findings provide preliminary evidence that PEERS is effective when administered as a 7-week program.
