Eye-Hand Coordination in Children with High Functioning Autism and Asperger’s Disorder Using a Gap-Overlap Paradigm / Alessandro CRIPPA in Journal of Autism and Developmental Disorders, 43-4 (April 2013)
[article]
Titre : Eye-Hand Coordination in Children with High Functioning Autism and Asperger’s Disorder Using a Gap-Overlap Paradigm Type de document : Texte imprimé et/ou numérique Auteurs : Alessandro CRIPPA, Auteur ; Sara FORTI, Auteur ; Paolo PEREGO, Auteur ; Massimo MOLTENI, Auteur Article en page(s) : p.841-850 Langues : Anglais (eng) Mots-clés : Autism Eye hand coordination Gap effect Oculomotor control Index. décimale : PER Périodiques Résumé : We investigated eye-hand coordination in children with autism spectrum disorders (ASD) in comparison with age-matched normally developing peers. The eye-hand correlation was measured by putting fixation latencies in relation with pointing and key pressing responses in visual detection tasks where a gap-overlap paradigm was used and compared to fixation latencies in absence of manual response. ASD patients showed less efficient eye-hand coordination, which was particularly evident when pointing towards a target was being fixated. The data of normally developing participants confirmed that manual gap effects are more likely for more complex hand movements. An important discrepancy was discovered in participants with ASD: beside normal eye gap effects, they showed no concurrent hand gap effects when pointing to targets. This result has been interpreted as a further sign of inefficient eye-hand coordination in this patient population.

Titre : Reduced visual disengagement but intact phasic alerting in young children with autism Type de document : Texte imprimé et/ou numérique Auteurs : Johan Lundin KLEBERG, Auteur ; Emilia THORUP, Auteur ; Terje FALCK-YTTER, Auteur Article en page(s) : p.539-545 Langues : Anglais (eng) Mots-clés : autism attention gap effect visual disengagement alerting orienting arousal Index. décimale : PER Périodiques Résumé : Children with autism may have difficulties with visual disengagement—that is, inhibiting current fixations and orienting to new stimuli in the periphery. These difficulties may limit these children's ability to flexibly monitor the environment, regulate their internal states, and interact with others. In typical development, visual disengagement is influenced by a phasic alerting network that increases the processing speed of the visual system after salient events. The role of the phasic alerting effect in the putative atypical disengagement performance in autism spectrum disorder (ASD) is not known. Here, we compared visual disengagement in six-year-old children with autism (N?=?18) and typically developing children (N?=?17) matched for age and nonverbal IQ. We manipulated phasic alerting during a visual disengagement task by adding spatially nonpredictive sounds shortly before the onset of the visual peripheral targets. Children with ASD showed evidence of delayed disengagement compared to the control group. Sounds facilitated visual disengagement similarly in both groups, suggesting typical modulation by phasic alerting in ASD in the context of this task. These results support the view that atypical visual disengagement in ASD is related to other factors than atypicalities in the alerting network.

It is unclear, however, whether these are specifically social differences; it is possible that they are a result of broader alterations in engaging and disengaging visual attention. We used eye-tracking technology with children with autism spectrum disorder (n = 35) and typical development (n = 32), showing them both social and nonsocial imaging to test their visual attention. Children with autism spectrum disorder had a significant difference in how long it took them to look from an image in the middle to one on the side, depending on whether the middle image stayed on the screen or flashed off before the one on the side appeared. This difference was present for both social and nonsocial images, and was related to cognitive ability for only the children with autism spectrum disorder. Our findings suggest that children with autism spectrum disorder have differences in general processes of engaging visual attention that are not specifically social in nature, and that these processes may relate to cognitive ability in autism spectrum disorder. Affected processes of visual engagement in autism spectrum disorder may contribute to symptoms like reduced eye contact, but social-specific symptoms of autism spectrum disorder likely do not stem from reduced visual engagement alone.
