An important key for increasing our understanding of ASD-specific social deficits may lie with the social motor synchronization that takes place when we implicitly coordinate our bodies with others. Here, we tested whether dynamical measures of synchronization differentiate children with ASD from controls and further explored the relationships between synchronization ability and motor control problems. We found (a) that children with ASD exhibited different and less stable patterns of social synchronization ability than controls; (b) children with ASD performed motor movements that were slower and more variable in both spacing and timing; and (c) some social synchronization that involved motor timing was related to motor ability but less rhythmic synchronization was not. These findings raise the possibility that objective dynamical measures of synchronization ability and motor skill could provide new insights into understanding the social deficits in ASD that could ultimately aid clinical diagnosis and prognosis.

A multiple deficit model of reading disability and attention-deficit/hyperactivity disorder: searching for shared cognitive deficits / Lauren M. MCGRATH in Journal of Child Psychology and Psychiatry, 52-5 (May 2011)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 52-5 (May 2011) . - p.547-557 Titre : A multiple deficit model of reading disability and attention-deficit/hyperactivity disorder: searching for shared cognitive deficits Type de document : Texte imprimé et/ou numérique Auteurs : Lauren M.

DEFRIES, Auteur ; Richard K. OLSON, Auteur Année de publication : 2011 Article en page(s) : p.547-557 Langues : Anglais (eng) Mots-clés : Reading disability  attention-deficit/hyperactivity disorder  processing speed  comorbidity  multiple deficit model Index. décimale : PER Périodiques Résumé : Background:  This study tests a multiple cognitive deficit model of reading disability (RD), attention-deficit/hyperactivity disorder (ADHD), and their comorbidity. Methods:  A structural equation model (SEM) of multiple cognitive risk factors and symptom outcome variables was constructed. The model included phonological awareness as a unique predictor of RD and response inhibition as a unique predictor of ADHD. Processing speed, naming speed, and verbal working memory were modeled as potential shared cognitive deficits. Results:  Model fit indices from the SEM indicated satisfactory fit. Closer inspection of the path weights revealed that processing speed was the only cognitive variable with significant unique relationships to RD and ADHD dimensions, particularly inattention. Moreover, the significant correlation between reading and inattention was reduced to non-significance when processing speed was included in the model, suggesting that processing speed primarily accounted for the phenotypic correlation (or comorbidity) between reading and inattention. Conclusions:  This study illustrates the power of a multiple deficit approach to complex developmental disorders and psychopathologies, particularly for exploring comorbidities. The theoretical role of processing speed in the developmental pathways of RD and ADHD and directions for future research are discussed.

Social Motor Synchronization: Insights for Understanding Social Behavior in Autism / Paula FITZPATRICK in Journal of Autism and Developmental Disorders, 47-7 (July 2017)

SCHMIDT, Auteur Article en page(s) : p.2092-2107 Langues : Anglais (eng) Mots-clés : Autism  Social synchronization  Dynamics  Social interaction Index. décimale : PER Périodiques Résumé : Impairments in social interaction and communication are critical features of ASD but the underlying processes are poorly understood. An under-explored area is the social motor synchronization that happens when we coordinate our bodies with others. Here, we explored the relationships between dynamical measures of social motor synchronization and assessments of ASD traits. We found (a) spontaneous social motor synchronization was associated with responding to joint attention, cooperation, and theory of mind while intentional social motor synchronization was associated with initiating joint attention and theory of mind; and (b) social motor synchronization was associated with ASD severity but not fully explained by motor problems. Findings suggest that objective measures of social motor synchronization may provide insights into understanding ASD traits.
