Basic oculomotor function is similar in young children with ASD and typically developing controls / Inbar AVNI in Autism Research, 14-12 (December 2021)
[article]
Titre : Basic oculomotor function is similar in young children with ASD and typically developing controls Type de document : Texte imprimé et/ou numérique Auteurs : Inbar AVNI, Auteur ; G. MEIRI, Auteur ; A. MICHAELOVSKI, Auteur ; I. MENASHE, Auteur ; L. SHMUELOF, Auteur ; I. DINSTEIN, Auteur Article en page(s) : p.2580-2591 Langues : Anglais (eng) Mots-clés : Adolescent Adult Autism Spectrum Disorder Child Child, Preschool Eye Movements Humans Infant Saccades eye position eye tracking gaze kinematic characteristics movies oculomotor control saccade Index. décimale : PER Périodiques Résumé : A variety of eye tracking studies have demonstrated that young children with ASD gaze at images and movies of social interactions differently than typically developing children. These findings have supported the hypothesis that gaze behavior differences are generated by a weaker preference for social stimuli in ASD children. The hypothesis assumes that gaze differences are not caused by abnormalities in oculomotor function including saccade frequency and kinematics. Previous studies of oculomotor function have mostly been performed with school-age children, adolescents, and adults using visual search, anti-saccade, and gap saccade tasks that are less suitable for young pre-school children. Here, we examined oculomotor function in 144 children (90 with ASD and 54 controls), 1-10-years-old, as they watched two animated movies interleaved with the presentation of multiple salient stimuli that elicited saccades-to-targets. The results revealed that the number of fixations, fixation duration, number of saccades, saccade duration, saccade accuracy, and saccade latency did not differ significantly across groups. Minor initial differences in saccade peak velocity were not supported by analysis with a linear mixed model. These findings suggest that most children with ASD exhibit similar oculomotor function to that of controls, when performing saccades-to-targets or freely viewing child-friendly movies. This suggests that previously reported gaze abnormalities in children with ASD are not due to underlying oculomotor deficiencies. LAY SUMMARY: This study demonstrates that children with ASD perform similar eye movements to those of controls when freely observing movies or making eye movements to targets. Similar results were apparent across groups in the number of eye movements, their accuracy, duration, and other measures that assess eye movement control. These findings are important for interpreting previously reported differences in gaze behavior of children with ASD, which are likely due to atypical social preferences rather than impaired control of eye movements.

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.
