Brief Report: Reduced Grouping Interference in Children with ASD: Evidence from a Multiple Object Tracking Task / Kris EVERS in Journal of Autism and Developmental Disorders, 44-7 (July 2014)

Titre : Brief Report: Reduced Grouping Interference in Children with ASD: Evidence from a Multiple Object Tracking Task Type de document : Texte imprimé et/ou numérique Auteurs : Kris EVERS, Auteur ; Lee DE-WIT, Auteur ; Ruth VAN DER HALLEN, Auteur ; Birgitt HAESEN, Auteur ; Jean STEYAERT, Auteur ; Ilse NOENS, Auteur ; Johan WAGEMANS, Auteur Article en page(s) : p.1779-1787 Langues : Anglais (eng) Mots-clés : Attention Autism spectrum disorder (ASD) Global interference Grouping Multiple object tracking Weak central coherence Index. décimale : PER Périodiques Résumé : This study was inspired by the more locally oriented processing style in autism spectrum disorders (ASD). A modified multiple object tracking (MOT) task was administered to a group of children with and without ASD. Participants not only had to distinguish moving targets from distracters, but they also had to track targets when they were visually grouped to distracters, a manipulation which has a detrimental effect on tracking performance in adults. MOT performance in the ASD group was also affected by grouping, but this effect was significantly reduced. This result highlights how the reduced bias towards more global processing in ASD could influence further stages of cognition by altering the way in which attention selects information for further processing.

Titre : A review of behavioural and electrophysiological studies on auditory processing and speech perception in autism spectrum disorders Type de document : Texte imprimé et/ou numérique Auteurs : Birgitt HAESEN, Auteur ; Bart BOETS, Auteur ; Johan WAGEMANS, Auteur Année de publication : 2011 Article en page(s) : p.701-714 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder Auditory processing Speech perception Local processing Global processing Index. décimale : PER Périodiques Résumé : This literature review aims to interpret behavioural and electrophysiological studies addressing auditory processing in children and adults with autism spectrum disorder (ASD). Data have been organised according to the applied methodology (behavioural versus electrophysiological studies) and according to stimulus complexity (pure versus complex tones versus speech sounds). In line with the weak central coherence (WCC) theory of autism we aimed to investigate whether individuals with ASD show a more locally and less globally oriented processing style in the auditory modality. To avoid the possible confound of stimulus complexity, this influence was taken into account as an additional hypothesis. The review reveals that the identification and discrimination of isolated acoustic features (in particular pitch processing) is generally intact or enhanced in individuals with ASD, for pure as well as for complex tones and speech sounds. It thus appears that the local processing advantage is not influenced by stimulus complexity. Individuals with ASD are also less susceptible to global interference of speech-like material. A deficit in global auditory processing, however, is less universally confirmed. We propose that the observed pattern of auditory enhancements and deficits in ASD may be related to an atypical pattern of right hemisphere dominance. As the right and left hemisphere are relatively more specialized in spectral versus temporal auditory processing, respectively, right hemisphere dominance in ASD could provoke enhanced pitch and vowel processing, whereas left hemisphere deficiencies might explain speech perception problems and temporal processing deficits.
