DIFFERENCES IN THE COGNITIVE FUNCTIONING OF PERSONS WITH WILLIAMS SYNDROME AND PERSONS WITH DOWN SYNDROME
Journal Title: Acta Neuropsychologica - Year 2012, Vol 10, Issue 2
Abstract
[b]Background:[/b] The goal of this study was to produce a precise picture of the cognitive profile of persons with Williams Syndrome (WS), through a comparison to the characteristic profile of persons with Down Syndrome (DS), another genetic disorder.[b]Material/Methods:[/b] We examined 35 persons with WS (average age 13.2 years) and a control group of persons with DS, matched for age and mental development. The research instruments used included Raven’s Colored Matrices, the Brief Intelligence Test, three subtests from the Wechsler Intelligence Scale for Children – Revised (Similarities, Picture Arranging, and Digit Recall), Piaget’s “left-right” test, a fragment from the MMSE, and a test of our own devising for recalling sensible verbal material.[b]Results:[/b] The WS group achieved better results than the DS group in respect to verbal intelligence, abstract thinking, cause-andeffect thinking, digit recall, and orientation in place and time. [b]Conclusions:[/b] WS has a significant impact on the affected person’s cognitive level and profile. In order to improve rehabilitation, it would be worthwhile to base interventions on relatively well preserved cognitive functions (verbal intelligence and word memory, including name recall) and social-emotional functions.
