Lough, Emma; Hanley, Mary; Rodgers, Jacqui; South, Mikle; Kirk, Hannah; Kennedy, Daniel P.; Riby, Deborah M. – Journal of Autism and Developmental Disorders, 2015
Interpersonal distance regulation is crucial for successful social interactions. We investigated personal space awareness in Williams syndrome (WS) and autism spectrum disorder (ASD) compared to typical development. Parents reported that individuals with WS and ASD were significantly more likely than those developing typically to invade the…

Mervis, Carolyn B. – Topics in Language Disorders, 2009
Williams syndrome is a rare neurodevelopmental disorder caused by deletion of approximately 25 genes on chromosome 7q11.23. Children with the syndrome evidence large individual differences in both broad language and reading abilities. Nevertheless, as a group, children with this syndrome show a consistent pattern characterized by relative…

Riby, D. M.; Kirk, H.; Hanley, M.; Riby, L. M. – Journal of Intellectual Disability Research, 2014
Background: The developmental disorder Williams syndrome (WS) is characterised by a distinctive cognitive profile and an intriguing social phenotype. Individuals with the disorder are often highly social engaging with familiar and unfamiliar people and once in an interaction they often show subtle abnormalities of social behaviour. Atypically…

D'Souza, Dean; D'Souza, Hana; Karmiloff-Smith, Annette – Journal of Child Language, 2017
In order to understand how language abilities emerge in typically and atypically developing infants and toddlers, it is important to embrace complexity in development. In this paper, we describe evidence that early language development is an experience-dependent process, shaped by diverse, interconnected, interdependent developmental mechanisms,…

Martens, Marilee A.; Seyfer, Daisha L.; Andridge, Rebecca R.; Foster, Jessica E. A.; McClure, Kelsey E.; Coury, Daniel L. – Research in Developmental Disabilities: A Multidisciplinary Journal, 2013
Williams syndrome (WS) is a genetic condition characterized by a unique neurocognitive and behavioral profile, including increased incidence of attention deficit/hyperactivity disorder (ADHD). The purpose of the present study was to examine the perceived helpfulness and side effects of medications used to treat ADHD (methylphenidate class,…

Van Herwegen, Jo; Dimitriou, Dagmara; Rundblad, Gabriella – Research in Developmental Disabilities: A Multidisciplinary Journal, 2013
This study investigated the development of novel metaphor and metonymy comprehension in both typically developing (TD) children and individuals with Williams syndrome (WS). Thirty-one TD children between the ages of 3;09 and 17;01 and thirty-four individuals with WS between the ages of 7;01 and 44 years old were administered a newly developed task…

Williams, Tracey A.; Porter, Melanie A.; Langdon, Robyn – Journal of Autism and Developmental Disorders, 2013
Fragile X syndrome (FXS) and Williams syndrome (WS) are both genetic disorders which present with similar cognitive-behavioral problems, but distinct social phenotypes. Despite these social differences both syndromes display poor social relations which may result from abnormal social processing. This study aimed to manipulate the location of…

Levy, Yonata; Eilam, Ariela – Journal of Child Language, 2013
This is a naturalistic study of the development of language in Hebrew-speaking children with Williams syndrome (WS) and children with Down syndrome (DS), whose MLU extended from 1[multiplied by]0 to 4[multiplied by]4. Developmental curves over the entire span of data collection revealed minor differences between children with WS, children with DS,…

Van Den Heuvel, E.; Manders, E.; Swillen, A.; Zink, I. – Journal of Intellectual Disability Research, 2016
Background: This study aimed to compare developmental courses of structural and pragmatic language skills in school-aged children with Williams syndrome (WS) and children with idiopathic intellectual disability (IID). Comparison of these language trajectories could highlight syndrome-specific developmental features. Method: Twelve monolingual…

Thomas, Michael S. C.; Van Duuren, Mike; Purser, Harry R. M.; Mareschal, Denis; Ansari, Daniel; Karmiloff-Smith, Annette – Journal of Experimental Child Psychology, 2010
The domain of figurative language comprehension was used to probe the developmental relation between language and cognition in typically developing individuals and individuals with Williams syndrome. Extending the work of Vosniadou and Ortony, the emergence of nonliteral similarity and category knowledge was investigated in 117 typically…

Hargrove, Patricia M.; Pittelko, Stephen; Fillingane, Evan; Rustman, Emily; Lund, Bonnie – Communication Disorders Quarterly, 2013
The purpose of this research was to compare selected speech and paralinguistic skills of speakers with Williams syndrome (WS) and typically developing peers and to demonstrate the feasibility of providing preexisting databases to students to facilitate graduate research. In a series of three studies, conversational samples of 12 adolescents with…

Ng, Rowena; Lai, Philip; Levitin, Daniel J.; Bellugi, Ursula – Journal of Mental Health Research in Intellectual Disabilities, 2013
Williams syndrome (WS) is a neurogenetic developmental disorder characterized by peaks and valleys of cognitive abilities. One peak that has been understudied is the affinity that many individuals with WS have with music. It remains unknown whether their high levels of musical interest, skill, and expressivity are related to their sociable…

Self, Michelle A. – ProQuest LLC, 2010
The purpose of this study was to describe and explore the experience of inclusion of students with Williams syndrome, a rare genetic condition of a microdeletion on chromosome 7 which has medical, behavior, and cognitive issues. The study was conducted by gaining an understanding from the parents' point of view. The study was twofold. First, the…

Levy, Yonata – Research in Developmental Disabilities: A Multidisciplinary Journal, 2011
This is a study of word decoding in adolescents with Down syndrome and in adolescents with Intellectual Deficits of unknown etiology. It was designed as a replication of studies of word decoding in English speaking and in Hebrew speaking adolescents with Williams syndrome ([0230] and [0235]). Participants' IQ was matched to IQ in the groups with…

Reilly, Colin; Murtagh, Lelia; Senior, Joyce – Journal of Research in Special Educational Needs, 2016
Research suggests that genetic syndromes associated with intellectual disability often have specific cognitive and behavioural profiles. It has been suggested that educational approaches need to reflect these profiles. Parents (n = 381) and teachers (n = 204) of children with one of four syndromes, fragile X syndrome, Prader-Willi syndrome,…
