Laughter Differs in Children with Autism: An Acoustic Analysis of Laughs Produced by Children With and Without the Disorder / William J. HUDENKO in Journal of Autism and Developmental Disorders, 39-10 (October 2009)

STONE, Auteur Année de publication : 2009 Article en page(s) : p.1392-1400 Langues : Anglais (eng) Mots-clés : Autism Laughter Emotion Affect Expression Acoustics Index. décimale : PER Périodiques Résumé : Few studies have examined vocal expressions of emotion in children with autism. We tested the hypothesis that during social interactions, children diagnosed with autism would exhibit less extreme laugh acoustics than their nonautistic peers. Laughter was recorded during a series of playful interactions with an examiner. Results showed that children with autism exhibited only one type of laughter, whereas comparison participants exhibited two types. No group differences were found for laugh duration, mean fundamental frequency (F0) values, change in F0, or number of laughs per bout. Findings are interpreted to suggest that children with autism express laughter primarily in response to positive internal states, rather than using laughter to negotiate social interactions.

Listeners prefer the laughs of children with autism to those of typically developing children / William J. HUDENKO in Autism, 16-6 (November 2012)  

Public ISBD [article]  inAutism > 16-6 (November 2012) . - p.641-655 Titre : Listeners prefer the laughs of children with autism to those of typically developing children Type de document : Texte imprimé et/ou numérique Auteurs : William J. HUDENKO, Auteur ; Michael A. MAGENHEIMER, Auteur Année de publication : 2012 Article en page(s) : p.641-655 Langues : Anglais (eng) Mots-clés : affect: autism  emotion  laughs  laughter  perception Index. décimale : PER Périodiques Résumé : The purpose of this study was to investigate the impact of laugh sounds produced by 8- to 10-year-old children with and without autism on naïve listeners, and to evaluate if listeners could distinguish between the laughs of the two groups. Results showed that listeners rated the laughs of children with autism more positively than the laughs of typically developing children, and that they were slightly above chance levels at judging which group produced the laugh. A subset of participants who reported listening for œuncontrolled � or œlonger � laughs were significantly better at discriminating between the laughs of the two groups. Our results suggest that the laughs of children with autism have the potential to promote the formation of relationships.
