Abstract

ABSTRACT: Only a few studies have investigated inhibitory sub-components in individuals with Down syndrome (DS). This study investigates interference suppression, through global-local processes, in 50 people with DS matched for mental age (MA) with 63 typically developing children (MA = 23.6 and 6.8 years respectively). We adapted and administered a non-verbal Navon-shape task with high-familiarity symbols. For both groups, results showed equal performance on global vs . local items in the congruent condition, whereas significantly better performance on global conditions when faced with incongruent items. A greater impairment in incongruent responses emerged for both groups and more so for individuals with DS.
