Goals: This study examined: (a) crystallized/fluid intelligence trajectories of adolescents and adults with Down syndrome; and (b) the contribution of endogenous (health, activities of daily living--ADL) and exogenous (cognitively stimulating leisure activities) factors on adults' intelligence with age. Method: Four cohorts (N = 80) with Down…

Patterson, T.; Rapsey, C. M.; Glue, P. – Journal of Intellectual Disability Research, 2013
Background: There is conjecture regarding the profile of cognitive development over time in children with Down syndrome (DS). Characterising this profile would be valuable for the planning and assessment of intervention studies. Method: A systematic search of the literature from 1990 to the present was conducted to identify longitudinal data on…

Couzens, Donna; Haynes, Michele; Cuskelly, Monica – Journal of Applied Research in Intellectual Disabilities, 2012
Background: Associations among cognitive development and intrapersonal and environmental characteristics were investigated for 89 longitudinal study participants with Down syndrome to understand developmental patterns associated with cognitive strengths and weaknesses. Materials and Methods: Subtest scores of the Stanford-Binet IV collected…

Rihtman, Tanya; Tekuzener, Esti; Parush, Shula; Tenenbaum, Alex; Bachrach, Steven J.; Ornoy, Asher – Developmental Medicine & Child Neurology, 2010
Aim: There is a lack of investigation into the functional developmental profile of children with Down syndrome. On the basis of current international health paradigms, the purpose of this study was to assess the developmental profile of these children. Method: Sixty children (33 males, 27 females) with Down syndrome (age range 6-16y; mean age 9y…

Peer reviewedHawkins, Barbara A.; Eklund, Susan J.; James, David R.; Foose, Alice K. – Mental Retardation, 2003
Fifty-eight adults with Down syndrome were assessed longitudinally over 10 years for the purpose of modeling aging-related change in cognitive function and adaptive behavior. Findings provide further evidence of changes in performance with age and include selected effects for participants who completed the study and those lost to follow-up.…
