Action coordination during a real-world task: Evidence from children with and without autism spectrum disorder / Dominic A. TREVISAN in Development and Psychopathology, 33-1 (February 2021)

Joint actions require accurate and rapid inferences about others' goals, intentions, and focus of attention, skills that are thought to be impaired in individuals with autism spectrum disorder (ASD). Research to date has not investigated joint action abilities in individuals with ASD during real-world social interactions. We conducted an experimental study that required children with ASD and typically developing children to move tables by themselves or collaboratively through a maze. This involved developing innovative methodologies for measuring action coordination-a critical component of the joint action process. We found that children with ASD are less likely to benefit from the collaboration of a peer than are typically developing children, and they are less likely to synchronize their steps when moving the table. However, these differences were masked when scaffolded by an adult. There was no evidence that ASD differences were due to gross motor delays in the participants with ASD. We argue that action coordination is a highly adaptive social process that is intrinsic to successful human functioning that manifests as atypical synchronization of mind and body in children with ASD.

Change Detection in Naturalistic Pictures Among Children with Autism / Jacob A. BURACK in Journal of Autism and Developmental Disorders, 39-3 (March 2009)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 39-3 (March 2009) . - p.471-479 Titre : Change Detection in Naturalistic Pictures Among Children with Autism Type de document : texte imprimé Auteurs : Jacob A. BURACK, Auteur ; Shari JOSEPH, Auteur ; Natalie RUSSO, Auteur ; David I. SHORE, Auteur ; Mafalda PORPORINO, Auteur ; James T. ENNS, Auteur Année de publication : 2009 Article en page(s) : p.471-479 Langues : Anglais (eng) Mots-clés : Change-detection Attention Development Index. décimale : PER Périodiques Résumé : Persons with autism often show strong reactions to changes in the environment, suggesting that they may detect changes more efficiently than typically developing (TD) persons. However, Fletcher-Watson et al. (Br J Psychol 97:537–554, 2006) reported no differences between adults with autism and TD adults with a change-detection task. In this study, we also found no initial differences in change-detection between children with autism and NVMA-matched TD children, although differences emerged when detection failures were related to the developmental level of the participants. Whereas detection failures decreased with increasing developmental level for TD children, detection failures remained constant over the same developmental range for children with autism, pointing to an atypical developmental trajectory for change-detection among children with autism.

The Comprehensive Autistic Trait Inventory (CATI): development and validation of a new measure of autistic traits in the general population / Michael C.W. ENGLISH in Molecular Autism, 12 (2021)  

Public ISBD [article]  inMolecular Autism > 12 (2021) . - 37 p. Titre : The Comprehensive Autistic Trait Inventory (CATI): development and validation of a new measure of autistic traits in the general population Type de document : texte imprimé Auteurs : Michael C.W. ENGLISH, Auteur ; Gilles E. GIGNAC, Auteur ; Troy A.W. VISSER, Auteur ; Andrew J.O. WHITEHOUSE, Auteur ; James T. ENNS, Auteur ; Murray T. MAYBERY, Auteur Article en page(s) : 37 p. Langues : Anglais (eng) Mots-clés : Autism  Autistic traits  Broader autism spectrum  Factor analysis  General population  Questionnaire  Self-report  Subscales Index. décimale : PER Périodiques Résumé : BACKGROUND: Traits and characteristics qualitatively similar to those seen in diagnosed autism spectrum disorder can be found to varying degrees in the general population. To measure these traits and facilitate their use in autism research, several questionnaires have been developed that provide broad measures of autistic traits [e.g. Autism-Spectrum Quotient (AQ), Broad Autism Phenotype Questionnaire (BAPQ)]. However, since their development, our understanding of autism has grown considerably, and it is arguable that existing measures do not provide an ideal representation of the trait dimensions currently associated with autism. Our aim was to create a new measure of autistic traits that reflects our current understanding of autism, the Comprehensive Autism Trait Inventory (CATI). METHODS: In Study 1, 107 pilot items were administered to 1119 individuals in the general population and exploratory factor analysis of responses used to create the 42-item CATI comprising six subscales: Social Interactions, Communication, Social Camouflage, Repetitive Behaviours, Cognitive Rigidity, and Sensory Sensitivity. In Study 2, the CATI was administered to 1068 new individuals and confirmatory factor analysis used to verify the factor structure. The AQ and BAPQ were administered to validate the CATI, and additional autistic participants were recruited to compare the predictive ability of the measures. In Study 3, to validate the CATI subscales, the CATI was administered to 195 new individuals along with existing valid measures qualitatively similar to each CATI subscale. RESULTS: The CATI showed convergent validity at both the total-scale (r ≥ .79) and subscale level (r ≥ .68). The CATI also showed superior internal reliability for total-scale scores (α = .95) relative to the AQ (α = .90) and BAPQ (α = .94), consistently high reliability for subscales (α > .81), greater predictive ability for classifying autism (Youden's Index = .62 vs .56-.59), and demonstrated measurement invariance for sex. LIMITATIONS: Analyses of predictive ability for classifying autism depended upon self-reported diagnosis or identification of autism. The autistic sample was not large enough to test measurement invariance of autism diagnosis. CONCLUSIONS: The CATI is a reliable and economical new measure that provides observations across a wide range of trait dimensions associated with autism, potentially precluding the need to administer multiple measures, and to our knowledge, the CATI is also the first broad measure of autistic traits to have dedicated subscales for social camouflage and sensory sensitivity.
