Howley, Sarah A.; Prasad, Sarah E.; Pender, Niall P.; Murphy, Kieran C. – Research in Developmental Disabilities: A Multidisciplinary Journal, 2012
22q11.2 Deletion Syndrome (22q11DS) is a common microdeletion disorder associated with mild to moderate intellectual disability and specific neurocognitive deficits, particularly in visual-motor and attentional abilities. Currently there is evidence that the visual-motor profile of 22q11DS is not entirely mediated by intellectual disability and…

Jansen, Brenda R. J.; De Lange, Eva; Van der Molen, Mariet J. – Research in Developmental Disabilities: A Multidisciplinary Journal, 2013
Adolescents with mild to borderline intellectual disability (MBID) often complete schooling without mastering basic math skills, even though basic math is essential for math-related challenges in everyday life. Limited attention to cognitive skills and low executive functioning (EF) may cause this delay. We aimed to improve math skills in an…

Van Herwegen, Jo; Farran, Emily; Annaz, Dagmara – Research in Developmental Disabilities: A Multidisciplinary Journal, 2011
Raven's Coloured Progressive Matrices (RCPM) is a standardised test that is commonly used to obtain a non-verbal reasoning score for children. As the RCPM involves the matching of a target to a pattern it is also considered to be a visuo-spatial perception task. RCPM is therefore frequently used in studies in Williams Syndrome (WS), in order to…
