Eye Movement Patterns and Approximate Number Sense Task Performance in Williams Syndrome and Down Syndrome: A Developmental Perspective / Jo VAN HERWEGEN in Journal of Autism and Developmental Disorders, 49-10 (October 2019)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 49-10 (October 2019) . - p.4030-4038 Titre : Eye Movement Patterns and Approximate Number Sense Task Performance in Williams Syndrome and Down Syndrome: A Developmental Perspective Type de document : texte imprimé Auteurs : Jo VAN HERWEGEN, Auteur ; Erica RANZATO, Auteur ; Annette KARMILOFF-SMITH, Auteur ; Victoria SIMMS, Auteur Article en page(s) : p.4030-4038 Langues : Anglais (eng) Mots-clés : Down syndrome  Eye movements  Number development  Williams syndrome Index. décimale : PER Périodiques Résumé : It has been reported that approximate number sense (ANS) task performance is impaired in individuals with Williams syndrome (WS) and Down syndrome (DS). Research with infants has suggested this impairment is caused by sticky fixation in WS and sustained attention deficits for those with DS. This study examined looking patterns of older children and adults with WS (n = 24) and DS (n = 23) during an ANS task compared to typically developing controls matched for chronological age and those matched for mental age. Results showed that, although there were no group differences, looking patterns changed with chronological age for both the WS and DS groups. Looking behaviour related to ANS performance only in the WS group. Implications for interventions are discussed.

Understanding Number Line Estimation in Williams Syndrome and Down Syndrome / Victoria SIMMS in Journal of Autism and Developmental Disorders, 50-2 (February 2020)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 50-2 (February 2020) . - p.583-591 Titre : Understanding Number Line Estimation in Williams Syndrome and Down Syndrome Type de document : texte imprimé Auteurs : Victoria SIMMS, Auteur ; Annette KARMILOFF-SMITH, Auteur ; Erica RANZATO, Auteur ; Jo VAN HERWEGEN, Auteur Article en page(s) : p.583-591 Langues : Anglais (eng) Mots-clés : Down Syndrome  Number familiarity  Number line estimation  Visuo-spatial skills  Williams Syndrome Index. décimale : PER Périodiques Résumé : Previous studies suggest that tasks dependent on the mental number line may be difficult for Williams Syndrome (WS) and Down Syndrome (DS) groups. However, few have directly assessed number line estimation in these groups. The current study assessed 28 WS, 25 DS and 25 typically developing (TD) participants in non-verbal intelligence, number familiarity, visuo-spatial skills and number line estimation. Group comparisons indicated no differences in number line estimation. However, the WS group displayed difficulties with visuo-spatial skills and the DS group displayed difficulties with number familiarity. Differential relationships between number line estimation and visuo-spatial/number familiarity skills were observed across groups. Data is discussed in the context of assessment of skills in neurodevelopmental disorders.
