VCFS EF edition:20 location:Dublin, Ireland date:19-21 July 2013
This presentation gives a group and individual analysis of broad cognitive abilities in children with 22q11.2 deletion syndrome achieved through use of the Cattell-Horn-Carroll (CHC) factor model (Flanagan, McGrew & Ortiz, 2000). The description of part scores and broad cognitive abilities allows us to look in depth to different facets of intelligence. Additionally, we focus on the structural language profiles of these children.
In this study we describe five different broad cognitive competences including fluid reasoning (Gf), crystallized intelligence (Gc), short term memory (Gsm), visual-spatial ability (Gv) and cognitive processing speed (Gs). Measurements are done by means of a contemporary intelligence battery based on subtests of the WISC-III-NL, the WPPSI-III-NL and the SON R6-40. The language profiles are based on the results of standardized language assessment with the PPVT-III-NL, the CELF-4-NL or the CELF-Preschool-2-NL.
In this presentation, we will give an overview of the wide range of performance of children with 22q11.2 deletion syndrome. The relationship between various aspects of cognition and linguistic parameters will be discussed, and the strength and weakness patterns will be highlighted.
