Verbal, Figural, and Arithmetic Fluency of Children with Cochlear Implants

Area of Science:

• Neuroscience
• Developmental Psychology
• Audiology

Background:

• Cochlear implantation (CI) offers significant benefits for children with prelingual severe hearing loss and deafness.
• Adequate rehabilitation post-CI is essential for developing auditory, speech, language, cognitive, and academic skills.
• Understanding cognitive functions like fluency in CI users is vital for optimizing their development.

Purpose of the Study:

• To analyze verbal, figural, and arithmetic fluency in children with cochlear implants (CI) compared to children with normal hearing (NH).
• To investigate the interrelationship between different types of fluency in both groups.
• To identify factors influencing fluency in children with CI.

Main Methods:

• Study included 46 children with CI and 110 children with NH, aged 9 to 16.
• Verbal fluency assessed via phonemic and semantic tasks.
• Non-verbal fluency measured using figural tasks.
• Arithmetic fluency evaluated with simple arithmetic problems (numbers up to 100).

Main Results:

• Children with CI demonstrated significantly poorer performance in phonemic fluency, semantic fluency, figural fluency, and arithmetic fluency compared to NH children.
• Positive correlations were observed between different fluency modalities in both groups.
• Girls with CI showed an advantage in phonemic fluency; age correlated with arithmetic fluency in the CI group.

Conclusions:

• Children with CI exhibit deficits across verbal, figural, and arithmetic fluency domains.
• The findings underscore the critical role of early auditory and language experiences in shaping cognitive fluency.
• Further research and targeted interventions are needed to support cognitive development in children with CI.
