Working memory, short-term memory and reading proficiency in school-age children with cochlear implants

Area of Science:

• Cognitive Psychology
• Neuroscience
• Speech and Hearing Sciences

Background:

• Children with cochlear implants (CIs) often face challenges in auditory processing and language development.
• Understanding their cognitive strengths and weaknesses, particularly in memory, is crucial for educational interventions.

Purpose of the Study:

• To investigate short-term memory (STM) and working memory (WM) abilities in school-aged children with CIs using both visual and auditory tasks.
• To explore the relationship between these memory skills and reading/language outcomes in this population.

Main Methods:

• Assessed STM and WM (auditory and visual) and verbal knowledge in 10 children (ages 7-11) with early-onset hearing loss using standardized cognitive tests.
• Evaluated reading outcomes using the Woodcock Reading Mastery Test III.

Main Results:

• Children with CIs performed within the average range for visual STM and WM but below average for auditory STM and WM.
• Verbal knowledge measures were also below average.
• Reading comprehension scores were below average and positively correlated with visual STM, visual WM, and auditory STM.

Conclusions:

• CI users demonstrated superior visual (spatial) memory skills compared to auditory memory skills.
• Visual WM significantly correlated with reading outcomes.
• WM capacity appears modality-specific in children with hearing loss, supporting the use of visual memory-based reading strategies.
