Efficiency of Executive Functions and Literacy Among Children With Specific Language Impairment

Abstract

Recently, extensive studies investigating executive functions in children with specific language impairment (SLI) have been performed. In the present study, we compared the level of executive functions (i.e., inhibitory control and cognitive flexibility) and literacy skills between 53 healthy children and 53 children with SLIs between the ages of 3 and 11 years. The groups were matched by age, gender and parental education level. Executive functions were assessed using the Children Card Sort, and the Literacy Assessment Battery was applied to measure literacy skills. The patients with SLI displayed a significantly lower level of cognitive flexibility than that of the healthy children. No significant differences were observed between the groups in inhibitory control and the majority of literacy skills. The results confirm the hypothesis that patients with SLI experience difficulties in cognitive flexibility.

Variability of Executive Function Performance in Preschoolers with Developmental Language Disorder

“…Several studies that have compared DCCS performance between children with and without DLD have found significantly better performance for typically developing children relative to the DLD group. 14,43,44 However, using this same task, Reichenbach et al 45 reported equivalent performance between DLD and typically developing groups. Yang and Gray 33 found no group differences in a nonverbal version of the DCCS, but reported that children with DLD performed significantly worse than typically developing peers on a verbal version of DCCS that required labeling.…”
