Direct linkLo, S. T.; Collin, P. J. L.; Hokken-Koelega, A. C. S. – Journal of Intellectual Disability Research, 2015
Background: Prader-Willi syndrome (PWS) is characterised by hypotonia, hypogonadism, short stature, obesity, behavioural problems, intellectual disability, and delay in language, social and motor development. There is very limited knowledge about visual-motor integration in children with PWS. Method: Seventy-three children with PWS aged 7-17 years…

Isaac, L.; Lincoln, A. – Journal of Intellectual Disability Research, 2011
Background: Williams syndrome (WMS) is a rare genetic disorder with an estimated prevalence of 1 in 20,000 live births. Among other characteristics, WMS has a distinctive cognitive profile with spared face processing and language skills that contrasts with impairment in the cognitive domains of spatial cognition, problem solving and planning. It…

Baker, S.; Hooper, S.; Skinner, M.; Hatton, D.; Schaaf, J.; Ornstein, P.; Bailey, D. – Journal of Intellectual Disability Research, 2011
Background: Working memory problems have been targeted as core deficits in individuals with Fragile X syndrome (FXS); however, there have been few studies that have examined working memory in young boys with FXS, and even fewer studies that have studied the working memory performance of young boys with FXS across different degrees of complexity.…

Menghini, D.; Addona, F.; Costanzo, F.; Vicari, S. – Journal of Intellectual Disability Research, 2010
Background: The present study was aimed at investigating working memory (WM) and executive functions capacities in individuals with Williams syndrome (WS) as compared with mental-age matched typically developing (TD) children. Method: In order to serve the study goal, a sizeable battery of tasks tapping WM as well as attention, memory, planning,…

Jacobson, C.; Shearer, J.; Habel, A.; Kane, F.; Tsakanikos, E.; Kravariti, E. – Journal of Intellectual Disability Research, 2010
Background: The 22q11.2 deletion syndrome (22qDS) confers high risk for intellectual disability and neuropsychological/academic impairment, although a minority of patients show average intelligence. Intellectual heterogeneity and the high prevalence of psychiatric diagnoses in earlier studies may have obscured the prototypical neuropsychological…

Key, A. P. F.; Dykens, E. M. – Journal of Intellectual Disability Research, 2008
Background: Prader-Willi syndrome (PWS) is a genetic disorder associated with intellectual disabilities, compulsivity, hyperphagia and increased risks of life-threatening obesity. Food preferences in people with PWS are well documented, but research has yet to focus on other properties of food in PWS, including composition and suitability for…

Kogan, C. S.; Boutet, I.; Cornish, K.; Graham, G. E.; Berry-Kravis, E.; Drouin, A.; Milgram, N. W. – Journal of Intellectual Disability Research, 2009
Background: Standardised neuropsychological and cognitive measures present some limitations in their applicability and generalisability to individuals with intellectual disability (ID). Alternative approaches to defining the cognitive signatures of various forms of ID are needed to advance our understanding of the profiles of strengths and…
