Titre : Auditory-motor rhythm synchronization in children with autism spectrum disorder Type de document : texte imprimé Auteurs : Ana TRYFON, Auteur ; Nicholas E.V. FOSTER, Auteur ; Tia OUIMET, Auteur ; Krissy DOYLE-THOMAS, Auteur ; Evdokia ANAGNOSTOU, Auteur ; Megha SHARDA, Auteur ; Krista L. 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.

Titre : Enhanced Memory for Vocal Melodies in Autism Spectrum Disorder and Williams Syndrome Type de document : texte imprimé Auteurs : Michael W. WEISS, Auteur ; Megha SHARDA, Auteur ; Miriam D. LENSE, Auteur ; Krista L. HYDE, Auteur ; Sandra E. TREHUB, Auteur Article en page(s) : p.1127-1133 Langues : Anglais (eng) Mots-clés : Adolescent Adult Auditory Perception Autism Spectrum Disorder/complications Child Humans Music Voice Williams Syndrome/complications Williams syndrome autism memory vocalization Index. décimale : PER Périodiques Résumé : Adults and children with typical development (TD) remember vocal melodies (without lyrics) better than instrumental melodies, which is attributed to the biological and social significance of human vocalizations. Here we asked whether children with autism spectrum disorder (ASD), who have persistent difficulties with communication and social interaction, and adolescents and adults with Williams syndrome (WS), who are highly sociable, even indiscriminately friendly, exhibit a memory advantage for vocal melodies like that observed in individuals with TD. We tested 26 children with ASD, 26 adolescents and adults with WS of similar mental age, and 26 children with TD on their memory for vocal and instrumental (piano, marimba) melodies. After exposing them to 12 unfamiliar folk melodies with different timbres, we required them to indicate whether each of 24 melodies (half heard previously) was old (heard before) or new (not heard before) during an unexpected recognition test. Although the groups successfully distinguished the old from the new melodies, they differed in overall memory. Nevertheless, they exhibited a comparable advantage for vocal melodies. In short, individuals with ASD and WS show enhanced processing of socially significant auditory signals in the context of music. LAY SUMMARY: Typically developing children and adults remember vocal melodies better than instrumental melodies. In this study, we found that children with Autistic Spectrum Disorder, who have severe social processing deficits, and children and adults with Williams syndrome, who are highly sociable, exhibit comparable memory advantages for vocal melodies. The results have implications for musical interventions with these populations.

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.

Titre : Fronto-Temporal Connectivity is Preserved During Sung but Not Spoken Word Listening, Across the Autism Spectrum Type de document : texte imprimé Auteurs : Megha SHARDA, Auteur ; Rashi MIDHA, Auteur ; Supriya MALIK, Auteur ; Shaneel MUKERJI, Auteur ; Nandini C. SINGH, Auteur Article en page(s) : p.174-186 Langues : Anglais (eng) Mots-clés : functional MRI diffusion tensor imaging (DTI) cognitive neuroscience pediatrics Index. décimale : PER Périodiques Résumé : Co-occurrence of preserved musical function with language and socio-communicative impairments is a common but understudied feature of Autism Spectrum Disorders (ASD). Given the significant overlap in neural organization of these processes, investigating brain mechanisms underlying speech and music may not only help dissociate the nature of these auditory processes in ASD but also provide a neurobiological basis for development of interventions. Using a passive-listening functional magnetic resonance imaging paradigm with spoken words, sung words and piano tones, we found that 22 children with ASD, with varying levels of functioning, activated bilateral temporal brain networks during sung-word perception, similarly to an age and gender-matched control group. In contrast, spoken-word perception was right-lateralized in ASD and elicited reduced inferior frontal gyrus (IFG) activity which varied as a function of language ability. Diffusion tensor imaging analysis reflected reduced integrity of the left hemisphere fronto-temporal tract in the ASD group and further showed that the hypoactivation in IFG was predicted by integrity of this tract. Subsequent psychophysiological interactions revealed that functional fronto-temporal connectivity, disrupted during spoken-word perception, was preserved during sung-word listening in ASD, suggesting alternate mechanisms of speech and music processing in ASD. Our results thus demonstrate the ability of song to overcome the structural deficit for speech across the autism spectrum and provide a mechanistic basis for efficacy of song-based interventions in ASD.
