Random and Short-Term Excessive Eye Movement in Children with Autism During Face-to-Face Conversation / Zhong ZHAO in Journal of Autism and Developmental Disorders, 52-8 (August 2022)
[article]
Titre : Random and Short-Term Excessive Eye Movement in Children with Autism During Face-to-Face Conversation Type de document : Texte imprimé et/ou numérique Auteurs : Zhong ZHAO, Auteur ; Jiayi XING, Auteur ; Xiaobin ZHANG, Auteur ; Xingda QU, Auteur ; Xinyao HU, Auteur ; Jianping LU, Auteur Article en page(s) : p.3699-3710 Langues : Anglais (eng) Mots-clés : Autism Spectrum Disorder Autistic Disorder Child Communication Eye Movements Humans Autism Entropy Eye movement quantity Eye tracking Face-to-face interaction Oculomotor Index. décimale : PER Périodiques Résumé : This study investigated the oculomotor performance in children with autism spectrum disorder (ASD) during a face-to-face conversation. A head mounted eye tracker recorded the eye movements in 20 children with ASD and 23 children with typical development (TD). Group comparisons were conducted on the randomness and the quantity of eye movement. The amount of time needed to reveal group difference was also examined. Results showed that the randomness of eye movement was significantly higher at all examined time durations, and the amount of eye movement was significantly greater within 3Â s in the ASD group. These findings demonstrated an atypical pattern of oculomotor dynamics in children ASD, which might facilitate the objective identification of ASD during daily social interaction.

PRUETT in Journal of Autism and Developmental Disorders, 41-6 (June 2011)
[article]
Titre : Social and Non-Social Cueing of Visuospatial Attention in Autism and Typical Development Type de document : Texte imprimé et/ou numérique Auteurs : John R. PRUETT, Auteur ; Angela LAMACCHIA, Auteur ; Sarah HOERTEL, Auteur ; Emma SQUIRE, Auteur ; Kelly MCVEY, Auteur ; Richard D. TODD, Auteur ; John N. CONSTANTINO, Auteur ; Steven E. PETERSEN, Auteur Année de publication : 2011 Article en page(s) : p.715-731 Langues : Anglais (eng) Mots-clés : Gaze Box Arrow Vision Oculomotor Child Index. décimale : PER Périodiques Résumé : Three experiments explored attention to eye gaze, which is incompletely understood in typical development and is hypothesized to be disrupted in autism. Experiment 1 (n = 26 typical adults) involved covert orienting to box, arrow, and gaze cues at two probabilities and cue-target times to test whether reorienting for gaze is endogenous, exogenous, or unique; experiment 2 (total n = 80: male and female children and adults) studied age and sex effects on gaze cueing. Gaze cueing appears endogenous and may strengthen in typical development. Experiment 3 tested exogenous, endogenous, and gaze-based orienting in 25 typical and 27 Autistic Spectrum Disorder (ASD) children. ASD children made more saccades, slowing their reaction times; however, exogenous and endogenous orienting, including gaze cueing, appear intact in ASD.

SCHUBERT, Auteur ; Krestin RADONOVICH, Auteur ; Keith D. WHITE, Auteur ; Mark H. LEWIS, Auteur Article en page(s) : p.251-266 Langues : Anglais (eng) Mots-clés : autism spectrum disorders vestibulo-ocular reflex sensorimotor cerebellum dysrhythmia oculomotor Index. décimale : PER Périodiques Résumé : Sensorimotor processing alterations are a growing focus in the assessment and treatment of Autism Spectrum Disorders (ASD). The rotational vestibulo-ocular reflex (rVOR), which functions to maintain stable vision during head movements, is a sensorimotor system that may be useful in understanding such alterations and their underlying neurobiology. In this study, we assessed post-rotary nystagmus elicited by continuous whole body rotation among children with high-functioning ASD and typically developing children. Children with ASD exhibited increased rVOR gain, the ratio of eye velocity to head velocity, indicating a possible lack of cerebellar inhibitory input to brainstem vestibular nuclei in this population. The ASD group also showed less regular or periodic horizontal eye movements as indexed by greater variance accounted for by multiple higher frequency bandwidths as well as greater entropy scores compared to typically developing children. The decreased regularity or dysrhythmia in the temporal structure of nystagmus beats in children with ASD may be due to alterations in cerebellum and brainstem circuitry. These findings could potentially serve as a model to better understand the functional effects of differences in these brain structures in ASD.
