Auditory Selective Attention Hindered by Visual Stimulus in Prelingually Deaf Children With Cochlear Implants.

Area of Science:

• Neuroscience
• Audiology
• Developmental Psychology

Background:

• Auditory selective attention is crucial for language development and learning.
• Children with prelingual deafness using cochlear implants (CI) may experience challenges in auditory processing.
• Visual distractors can impact cognitive tasks, particularly attention.

Purpose of the Study:

• To investigate the effect of visual distractors on auditory selective attention in children with CIs versus normal-hearing children.
• To compare reaction times and accuracy (d') in an auditory identification task under varying visual conditions.

Main Methods:

• Recruited 22 children with CIs and 16 normal-hearing children (aged 6-7 years).
• Participants completed an auditory identification task with and without visual stimuli.
• Measured reaction times and discriminability (d') to assess auditory attention performance.

Main Results:

• Normal-hearing children exhibited faster reaction times than the CI group.
• The normal-hearing group showed significantly better discriminability (d') in the presence of visual distractors (p=0.012).
• No significant difference in discriminability was found between groups without visual distraction (p=0.493).

Conclusions:

• Visual distractors significantly impair auditory attention performance in children with CIs compared to their normal-hearing peers.
• Enhanced visual processing in CI users may consume limited attentional resources, hindering auditory perception.
• These findings highlight the complex interplay between visual and auditory attention in pediatric CI users.
