Comparative executive function analysis: Cochlear implants and normal hearing in 7- to 11-year-old children from Iran.

This study compares executive functioning in deaf children with cochlear implants and those with normal hearing. Individuals who lacked auditory stimulation during their early years might experience cognitive challenges that extend beyond just speech and language abilities. The executive functioning abilities of a group of 32 children who were born deaf and received cochlear implants before the age of 7 were contrasted with those of 30 children with normal hearing. Both sets of children underwent assessments using the Tower of London, BRIEF, and Stroop tests. The average score on the Tower of London task reveals that children who received cochlear implants (4.03 ± 2.53) achieved lower scores than typically hearing children (8.37 ± 2.79). This group also exhibited higher errors in the Stroop test and slightly longer response times Additionally, in terms of emotional control assessed by the BRIEF, a higher score was recorded. Notably, significant differences between the two groups were identified for organizing materials (t(62) = -4.204, The significant differences in data between both groups suggest the influence of cochlear implantation on cognitive functions. This emphasizes the importance of a holistic approach to supporting the overall development of these children.
