Thirty-two parents or guardians of individuals with WS (Mage = 24.76 years, SD = 7.55) were included. Associations between anxiety, intolerance of uncertainty, sensory hyper-sensitivity, and ASD symptoms were assessed. Linear regression analysis revealed that intolerance of uncertainty and sensory hyper-sensitivity were unique independent predictors of anxiety, while social communication score was not. There was evidence of a mediating effect of sensory hyper-sensitivity on the relationship between intolerance of uncertainty and anxiety. These findings bear strong resemblance to the pattern seen in ASD and emphasize the need for development of anxiety interventions that attempt to reduce negative beliefs about unpredictable situations in WS.

Social affiliation motives modulate spontaneous learning in Williams syndrome but not in autism / G. VIVANTI in Molecular Autism, 7 (2016)  

Public ISBD [article]  inMolecular Autism > 7 (2016) . - 40p. Titre : Social affiliation motives modulate spontaneous learning in Williams syndrome but not in autism Type de document : Texte imprimé et/ou numérique Auteurs : G. VIVANTI, Auteur ; D. R. HOCKING, Auteur ; P. FANNING, Auteur ; Cheryl DISSANAYAKE, Auteur Article en page(s) : 40p. Langues : Anglais (eng) Mots-clés : Attention  Autistic Disorder/psychology  Child, Preschool  Female  Humans  Learning  Male  Williams Syndrome/psychology  Autism  Imitation  Social cognition  Social learning  Williams syndrome Index. décimale : PER Périodiques Résumé : BACKGROUND: Children with autism spectrum disorder (ASD) and those with Williams syndrome (WS) have difficulties with learning, though the nature of these remains unclear. METHODS: In this study, we used novel eye-tracking and behavioral paradigms to measure how 36 preschoolers with ASD and 21 age- and IQ-matched peers with WS attend to and learn novel behaviors (1) from the outcomes of their own actions (non-social learning), (2) through imitation of others' actions (social learning), and across situations in which imitative learning served either an instrumental function or fulfilled social affiliation motives. RESULTS: The two groups demonstrated similar abilities to learn from the consequences of their own actions and to imitate new actions that were instrumental to the achievement of a tangible goal. Children with WS, unlike those with ASD, increased their attention and imitative learning performance when the model acted in a socially engaging manner. CONCLUSIONS: Learning abnormalities in ASD appear to be linked to the social rather than instrumental dimensions of learning.

Verbal labels increase the salience of novel objects for preschoolers with typical development and Williams syndrome, but not in autism / G. VIVANTI in Journal of Neurodevelopmental Disorders, 8-1 (December 2016)  

Public ISBD [article]  inJournal of Neurodevelopmental Disorders > 8-1 (December 2016) . - p.46 Titre : Verbal labels increase the salience of novel objects for preschoolers with typical development and Williams syndrome, but not in autism Type de document : Texte imprimé et/ou numérique Auteurs : G. VIVANTI, Auteur ; D. R. HOCKING, Auteur ; P. FANNING, Auteur ; Cheryl DISSANAYAKE, Auteur Article en page(s) : p.46 Langues : Anglais (eng) Mots-clés : Autism  Referential communication  Social learning  Williams syndrome Index. décimale : PER Périodiques Résumé : BACKGROUND: Early research has documented that young children show an increased interest toward objects that are verbally labeled by an adult, compared to objects that are presented without a label. It is unclear whether the same phenomenon occurs in neurodevelopmental disorders affecting social development, such as autism spectrum disorder (ASD) and Williams syndrome (WS). METHODS: The present study used a novel eye-tracking paradigm to determine whether hearing a verbal label increases the salience of novel objects in 35 preschoolers with ASD, 18 preschoolers with WS, and 20 typically developing peers. RESULTS: We found that typically developing children and those with WS, but not those with ASD, spent significantly more time looking at objects that are verbally labeled by an adult, compared to objects that are presented without a label. CONCLUSIONS: In children without ASD, information accompanied by the speaker's verbal label is accorded a "special status," and it is more likely to be attended to. In contrast, children with ASD do not appear to attribute a special salience to labeled objects compared to non-labeled objects. This result is consistent with the notion that reduced responsivity to pedagogical cues hinders social learning in young children with ASD.
