Direct linkD'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,…

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,…

Skwerer, Daniela Plesa; Ammerman, Emily; Tager-Flusberg, Helen – Journal of Child Language, 2013
Research on language in individuals with Williams syndrome (WS) has been fueled by persistent theoretical controversies for two decades. These shifted from initial focus on dissociations between language and cognition functions, to examining the paradox of socio-communicative impairments despite high sociability and relatively proficient…

Lukacs, Agnes; Pleh, Csaba; Racsmany, Mihaly – Journal of Child Language, 2007
We present data on the language of space in Hungarian individuals with Williams syndrome (WS; 19 in the first, 15 in the second study, between 8;0 and 21;11) and a verbal control (VC) group of typically developing (TD; 19 in the first, 15 in the second study, between 3;5 and 10;7) children from: (1) a study of elicited production and comprehension…

Peer reviewedStevens, Tassos; Karmiloff-Smith, Annette – Journal of Child Language, 1997
This study examines the processes underlying vocabulary acquisition, i.e., how new words are learned, in children with Williams Syndrome, a rare neurodevelopmental disorder. A Williams Syndrome group was compared to groups of normal controls in the range 3-9 years in four different experiments testing for constraints on word learning. (Author/JL)

Levy, Yonata – Journal of Child Language, 2004
Williams syndrome (WS) is often cited as the prime example within developmental disorders of the dissociation of language from other cognitive skills, particularly from visuo-motor skills. This claim has been responsible for the challenges posed by this population to cognitive theories and to models of language acquisition. Two Hebrew-speaking…
