This inconsistency and uncertainty may be the product of different theoretical and methodological approaches used to define attention in autism. In the current study, we investigate whether the allocation of attentional resources to task demands, and attention resource capacity, differs between autistics with no comorbid attention-deficit diagnosis (n = 55) and age-matched neurotypicals (n = 55). We compared differences in capacity and the allocation of resources by manipulating attentional load in a Multiple Object-Tracking (MOT) task, a robust, versatile, and ecological measure of selective, sustained, and distributed attention. While autistics demonstrated lower MOT performance, this difference disappeared when we accounted for fluid reasoning intelligence. Additionally, the similarity in the trend of MOT performance at increasing levels of attentional load between autistics and neurotypicals suggests no differences in the allocation of attentional resources to task demands. Taken together, our study suggests that higher-order cognitive abilities, such as intelligence, should be considered when characterizing attention across the autistic population in research. Similarly, our findings highlight the importance of considering cognitive competence when assessing attentional capabilities in autistic individuals, which could have significant implications for clinical diagnosis, treatment, and support.

Perception of emotion in musical performance in adolescents with autism spectrum disorders / Anjali BHATARA in Autism Research, 3-5 (October 2010)  

Public ISBD [article]  inAutism Research > 3-5 (October 2010) . - p.214-225 Titre : Perception of emotion in musical performance in adolescents with autism spectrum disorders Type de document : Texte imprimé et/ou numérique Auteurs : Anjali BHATARA, Auteur ; Eve-Marie QUINTIN, Auteur ; Bianca LEVY, Auteur ; Ursula BELLUGI, Auteur ; Eric FOMBONNE, Auteur ; Daniel J. LEVITIN, Auteur Année de publication : 2010 Article en page(s) : p.214-225 Langues : Anglais (eng) Mots-clés : autism spectrum disorders  Asperger syndrome  Williams syndrome  music  emotion perception  auditory perception Index. décimale : PER Périodiques Résumé : Individuals with autism spectrum disorders (ASD) are impaired in understanding the emotional undertones of speech, many of which are communicated through prosody. Musical performance also employs a form of prosody to communicate emotion, and the goal of this study was to examine the ability of adolescents with ASD to understand musical emotion. We designed an experiment in which each musical stimulus served as its own control while we varied the emotional expressivity by manipulating timing and amplitude variation. We asked children and adolescents with ASD and matched controls as well as individuals with Williams syndrome (WS) to rate how emotional these excerpts sounded. Results show that children and adolescents with ASD are impaired relative to matched controls and individuals with WS at judging the difference in emotionality among the expressivity levels. Implications for theories of emotion in autism are discussed in light of these findings.
