Gaze Performance in Children with Autism Spectrum Disorder when Observing Communicative Actions / Terje FALCK-YTTER in Journal of Autism and Developmental Disorders, 42-10 (October 2012)

Gaze measures included the children’s spontaneous tendency to look at the correct (attended) toy, and the latency of their correct responses. In addition to group differences (AD vs. TD), we found that in AD, accuracy of performance was specifically related to adaptive communication skills. The study also indicated that the latency of correct gaze shifts is related to verbal intelligence. These results have direct implications for our understanding of (responsive) joint attention impairments in AD.

How children with autism look at events / Claes VON HOFSTEN in Research in Autism Spectrum Disorders, 3-2 (April-june 2009)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 3-2 (April-june 2009) . - p.556-569 Titre : How children with autism look at events Type de document : Texte imprimé et/ou numérique Auteurs : Claes VON HOFSTEN, Auteur ; Helena UHLIG, Auteur ; Malin ADELL, Auteur ; Olga KOCHUKHOVA, Auteur Année de publication : 2009 Article en page(s) : p.556-569 Langues : Anglais (eng) Mots-clés : Eye-tracking Preschool-children Visual-motion-perception Predictive-abilities Social-perception Index. décimale : PER Périodiques Résumé : Patterns of eye movements were studied in a group of 10 preschool children with Autism Spectrum Disorder (ASD) and in two reference groups with typically developing (TD) children, 12 3-year-olds and 12 1-year-olds. Three hypotheses were tested regarding the origins of problems experienced by children with ASD in dynamic situations. The first one stated that the children with ASD have deficient motion perception. The second one stated that children with ASD are deficient in predicting events, and the third one that the roots are to be found in deficient social perception. The results show that the children with ASD tracked moving objects with smooth pursuit and predicted the reappearance of temporarily occluded moving object in the same way as the TD children. Their eye movements, however, revealed deficient social perception. They looked at a video-taped conversation much less than the TD children, they did not predict the onset of the next turn in the conversation, and the fixations on the speakers were shorter. These effects did not appear in a control video with objects taking turns and making sounds in a similar alternating way to the two participants in the conversation.

Visually directed reaching of children with motor impairments / Agneta FORSSTROM in Developmental Medicine & Child Neurology, 24-5 (October 1982)

Public ISBD [article]  inDevelopmental Medicine & Child Neurology > 24-5 (October 1982) . - p.653-661 Titre : Visually directed reaching of children with motor impairments Type de document : Texte imprimé et/ou numérique Auteurs : Agneta FORSSTROM, Auteur ; Claes VON HOFSTEN, Auteur Année de publication : 1982 Article en page(s) : p.653-661 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Impaired postural fixation affects the efficiency and flexibility of impending movements. 38 children aged between four and 11 years with abnormal postural fixation associated with slight neurological disturbances were studied, together with a matched control group, when reaching for a moving object. 298 reaches from each group were analysed by a technique which took into account the three-dimensional properties of the reaches. Acceleration profiles were analysed and used to divide reaches into movement elements. The aiming of those elements were calculated and compared with an optimal value. The test indicated the following: the relative lengths of approach paths was greater for the children in the clinical group than for the controls; the neurologically impaired children were less apt than the controls to increase the efficiency of their reaching patterns; but they took their less efficient motor performance into account when planning the reach and aimed further ahead of the target than the controls.

Young children with Autism Spectrum Disorder look differently at positive versus negative emotional faces / Tessa C.J. DE WIT in Research in Autism Spectrum Disorders, 2-4 (October 2008)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 2-4 (October 2008) . - p.651-659 Titre : Young children with Autism Spectrum Disorder look differently at positive versus negative emotional faces Type de document : Texte imprimé et/ou numérique Auteurs : Tessa C.J.

Typically, adults show specific viewing patterns while scanning positive and negative emotional expressions in faces. In this study, we investigated whether the same pattern is present in a group of 3- to 6-year-old children with ASD and a 5-year-old control group. We found that although the group with ASD looked less at feature areas of the face (eye, mouth, nose) than the control group, both the children with ASD and the normally developing children displayed differential scanning patterns for faces displaying positive and negative emotions. Specifically, we found increased scanning of the eye region when looking at faces displaying negative emotions. This study shows that, although young children with ASD exhibit abnormal face scanning patterns, they do exhibit differential viewing strategies while scanning positive and negative facial expressions.
