Dyspraxia and autistic traits in adults with and without autism spectrum conditions / Sarah A. CASSIDY in Molecular Autism, 7 (2016)
[article]
Titre : Dyspraxia and autistic traits in adults with and without autism spectrum conditions Type de document : Texte imprimé et/ou numérique Auteurs : Sarah A. CASSIDY, Auteur ; P. HANNANT, Auteur ; Teresa TAVASSOLI, Auteur ; Carrie ALLISON, Auteur ; P. SMITH, Auteur ; Simon BARON-COHEN, Auteur Article en page(s) : 48p. Langues : Anglais (eng) Mots-clés : Adolescent Adult Aged Apraxias/complications/physiopathology/psychology Autism Spectrum Disorder/complications/physiopathology/psychology Autistic Disorder/complications/physiopathology/psychology Case-Control Studies Empathy Female Humans Male Middle Aged Phenotype Psychological Tests Psychomotor Performance Social Skills Surveys and Questionnaires Autism spectrum conditions Autistic traits Co-morbidity Dyspraxia Index. décimale : PER Périodiques Résumé : BACKGROUND: Autism spectrum conditions (ASC) are frequently associated with motor coordination difficulties. However, no studies have explored the prevalence of dyspraxia in a large sample of individuals with and without ASC or associations between dyspraxia and autistic traits in these individuals. METHODS: Two thousand eight hundred seventy-one adults (with ASC) and 10,706 controls (without ASC) self-reported whether they have been diagnosed with dyspraxia. A subsample of participants then completed the Autism Spectrum Quotient (AQ; 1237 ASC and 6765 controls) and the Empathy Quotient (EQ; 1147 ASC and 6129 controls) online through the Autism Research Centre website. The prevalence of dyspraxia was compared between those with and without ASC. AQ and EQ scores were compared across the four groups: (1) adults with ASC with dyspraxia, (2) adults with ASC without dyspraxia, (3) controls with dyspraxia, and (4) controls without dyspraxia. RESULTS: Adults with ASC were significantly more likely to report a diagnosis of dyspraxia (6.9%) than those without ASC (0.8%). In the ASC group, those with co-morbid diagnosis of dyspraxia did not have significantly different AQ or EQ scores than those without co-morbid dyspraxia. However, in the control group (without ASC), those with dyspraxia had significantly higher AQ and lower EQ scores than those without dyspraxia. CONCLUSIONS: Dyspraxia is significantly more prevalent in adults with ASC compared to controls, confirming reports that motor coordination difficulties are significantly more common in this group. Interestingly, in the general population, dyspraxia was associated with significantly higher autistic traits and lower empathy. These results suggest that motor coordination skills are important for effective social skills and empathy.

Titre : Dyspraxia in ASD: Impaired coordination of movement elements Type de document : Texte imprimé et/ou numérique Auteurs : Danielle MCAULIFFE, Auteur ; Ajay S. PILLAI, Auteur ; Alyssa TIEDEMANN, Auteur ; Stewart H. MOSTOFSKY, Auteur ; Joshua B. EWEN, Auteur Article en page(s) : p.648-652 Langues : Anglais (eng) Mots-clés : dyspraxia autism motor planning divided attention multiple task interference Index. décimale : PER Périodiques Résumé : Children with autism spectrum disorders (ASD) have long been known to have deficits in the performance of praxis gestures; these motor deficits also correlate with social and communicative deficits. To date, the precise nature of the errors involved in praxis has not been clearly mapped out. Based on observations of individuals with ASD performing gestures, we hypothesized that the simultaneous execution of multiple movement elements is especially impaired in affected children. We examined 25 school-aged participants with ASD and 25 age-matched controls performing seven simultaneous gestures that required the concurrent performance of movement elements and nine serial gestures, in which all elements were performed serially. There was indeed a group × gesture-type interaction (P?0.001). Whereas both groups had greater difficulty performing simultaneous than serial gestures, children with ASD had a 2.6-times greater performance decrement with simultaneous (vs. serial) gestures than controls. These results point to a potential deficit in the simultaneous processing of multiple inputs and outputs in ASD. Such deficits could relate to models of social interaction that highlight the parallel-processing nature of social communication.

Titre : Exploring the Relationship Between Gestural Recognition and Imitation: Evidence of Dyspraxia in Autism Spectrum Disorders Type de document : Texte imprimé et/ou numérique Auteurs : Heidi STIEGLITZ HAM, Auteur ; Angela BARTOLO, Auteur ; Martin CORLEY, Auteur ; Gnanathusharan RAJENDRAN, Auteur ; Aniko SZABO, Auteur ; Sara SWANSON, Auteur Année de publication : 2011 Article en page(s) : p.1-12 Langues : Anglais (eng) Mots-clés : Autism spectrum disorders Dyspraxia Gestural recognition Imitation Index. décimale : PER Périodiques Résumé : In this study, the relationship between gesture recognition and imitation was explored. Nineteen individuals with Autism Spectrum Disorder (ASD) were compared to a control group of 23 typically developing children on their ability to imitate and recognize three gesture types (transitive, intransitive, and pantomimes). The ASD group performed more poorly than controls on all tasks of recognition and imitation. Higher performance on tests of working memory was associated with increased odds of successful imitation in both groups. Group differences remained even when working memory was statistically controlled for. An association was revealed in the ASD group between pantomime recognition and imitation but a similar association was not identified for intransitive gestures suggesting that recognition alone is not sufficient for imitation success.

PILLAI, Auteur ; Katarina AMENT, Auteur ; Jack ADAMEK, Auteur ; Brian S. CAFFO, Auteur ; Stewart H. MOSTOFSKY, Auteur ; Joshua B. EWEN, Auteur Article en page(s) : p.777-784 Langues : Anglais (eng) Mots-clés : autism dyspraxia imitation learning motor control skill learning Index. décimale : PER Périodiques Résumé : Autism spectrum disorder (ASD) consists of altered performance of a range of skills, including social/communicative and motor skills. It is unclear whether this altered performance results from atypical acquisition or learning of the skills or from atypical "online" performance of the skills. Atypicalities of skilled actions that require both motor and cognitive resources, such as abnormal gesturing, are highly prevalent in ASD and are easier to study in a laboratory context than are social/communicative skills. Imitation has long been known to be impaired in ASD; because learning via imitation is a prime method by which humans acquire skills, we tested the hypothesis that children with ASD show alterations in learning novel gestures via imitation. Eighteen participants with ASD and IQ > 80, ages 8-12.9 years, and 19 typically developing peers performed a task in which they watched a video of a model performing a novel, meaningless arm/hand gesture and copied the gesture. Each gesture video/copy sequence was repeated 4-6 times. Eight gestures were analyzed. Examination of learning trajectories revealed that while children with ASD made nearly as much progress in learning from repetition 1 to repetition 4, the shape of the learning curves differed. Causal modeling demonstrated the shape of the learning curve influenced both the performance of overlearned gestures and autism severity, suggesting that it is in the index of learning mechanisms relevant both to motor skills and to autism core features. Autism Res 2020, 13: 777-784.. (c) 2019 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: Imitation is a route by which humans learn a wide range of skills, naturally and in therapies. Imitation is known to be altered in autism spectrum disorder (ASD), but learning via imitation has not been rigorously examined. We found that the shape of the learning curve is altered in ASD, in a way that has a significant impact both on measures of autism severity and of other motor skills.
