Acoustic and Perceptual Measurement of Expressive Prosody in High-Functioning Autism: Increased Pitch Range and What it Means to Listeners / Aparna NADIG in Journal of Autism and Developmental Disorders, 42-4 (April 2012) 

Public ISBD [article]  in Journal of Autism and Developmental Disorders > 42-4 (April 2012) . - p.499-511 Titre : Acoustic and Perceptual Measurement of Expressive Prosody in High-Functioning Autism: Increased Pitch Range and What it Means to Listeners Type de document : texte imprimé Auteurs : Aparna NADIG, Auteur Année de publication : 2012 Article en page(s) : p.499-511 Langues : Anglais (eng) Catégories : AUTISME DE HAUT NIVEAU PERCEPTION PROSODIE Mots-clés : High-functioning autism  Expressive prosody  Acoustic measurements  Pitch variability  Perceptual judgments Index. décimale : PER Périodiques Résumé : Are there consistent markers of atypical prosody in speakers with high functioning autism (HFA) compared to typically-developing speakers? We examined: (1) acoustic measurements of pitch range, mean pitch and speech rate in conversation, (2) perceptual ratings of conversation for these features and overall prosody, and (3) acoustic measurements of speech from a structured task. Increased pitch range was found in speakers with HFA during both conversation and structured communication. In global ratings listeners rated speakers with HFA as having atypical prosody. Although the HFA group demonstrated increased acoustic pitch range, listeners did not rate speakers with HFA as having increased pitch variation. We suggest that the quality of pitch variation used by speakers with HFA was non-conventional and thus not registered as such by listeners.

Adaptation of object descriptions to a partner under increasing communicative demands: a comparison of children with and without autism / Aparna NADIG in Autism Research, 2-6 (December 2009) 

Public ISBD [article]  in Autism Research > 2-6 (December 2009) . - p.334-347 Titre : Adaptation of object descriptions to a partner under increasing communicative demands: a comparison of children with and without autism Type de document : texte imprimé Auteurs : Aparna NADIG, Auteur ; Giacomo VIVANTI, Auteur ; Sally OZONOFF, Auteur Article en page(s) : p.334-347 Langues : Anglais (eng) Mots-clés : social-cognition developmental-psychology Index. décimale : PER Périodiques Résumé : This study compared the object descriptions of school-age children with high-functioning autism (HFA) with those of a matched group of typically developing children. Descriptions were elicited in a referential communication task where shared information was manipulated, and in a guessing game where clues had to be provided about the identity of an object that was hidden from the addressee. Across these tasks, increasingly complex levels of audience design were assessed: (1) the ability to give adequate descriptions from one's own perspective, (2) the ability to adjust descriptions to an addressee's perspective when this differs from one's own, and (3) the ability to provide indirect yet identifying descriptions in a situation where explicit labeling is inappropriate. Results showed that there were group differences in all three cases, with the HFA group giving less efficient descriptions with respect to the relevant context than the comparison group. More revealing was the identification of distinct adaptation profiles among the HFA participants: those who had difficulty with all three levels, those who displayed Level 1 audience design but poor Level 2 and Level 3 design, and those demonstrated all three levels of audience design, like the majority of the comparison group. Higher structural language ability, rather than symptom severity or social skills, differentiated those HFA participants with typical adaptation profiles from those who displayed deficient audience design, consistent with previous reports of language use in autism.

Brief Report: Conveying Subjective Experience in Conversation: Production of Mental State Terms and Personal Narratives in Individuals with High Functioning Autism / Janet BANG in Journal of Autism and Developmental Disorders, 43-7 (July 2013) 

Public ISBD [article]  in Journal of Autism and Developmental Disorders > 43-7 (July 2013) . - p.1732-1740 Titre : Brief Report: Conveying Subjective Experience in Conversation: Production of Mental State Terms and Personal Narratives in Individuals with High Functioning Autism Type de document : texte imprimé Auteurs : Janet BANG, Auteur ; Jesse BURNS, Auteur ; Aparna NADIG, Auteur Année de publication : 2013 Article en page(s) : p.1732-1740 Langues : Anglais (eng) Mots-clés : High-functioning autism  Conversation  Personal narrative  Mental state terms Index. décimale : PER Périodiques Résumé : Mental state terms and personal narratives are conversational devices used to communicate subjective experience in conversation. Pre-adolescents with high-functioning autism (HFA, n = 20) were compared with language-matched typically-developing peers (TYP, n = 17) on production of mental state terms (i.e., perception, physiology, desire, emotion, cognition) and personal narratives (sequenced retelling of life events) during short conversations. HFA and TYP participants did not differ in global use of mental state terms, nor did they exhibit reduced production of cognitive terms in particular. Participants with HFA produced significantly fewer personal narratives. They also produced a smaller proportion of their mental state terms during personal narratives. These findings underscore the importance of assessing and developing qualitative aspects of conversation in highly verbal individuals with autism.

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]  in Research 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 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.
