Picture naming and verbal fluency in children with cochlear implants

Area of Science:

• Linguistics
• Audiology
• Developmental Psychology

Background:

• Children with cochlear implants (CIs) may experience challenges in language development due to altered auditory input.
• Lexical access and organization are crucial for effective communication and academic success.

Purpose of the Study:

• To investigate lexical naming abilities in children with CIs.
• To determine if children with CIs exhibit deficits in lexical access and organization using picture-naming and verbal fluency tasks.

Main Methods:

• Compared 20 children with CIs (ages 7-10) to 20 age- and IQ-matched children with normal hearing (NH).
• Assessed lexical abilities via a timed picture-naming task (lexical access) and phonological/semantic verbal fluency tasks (lexical organization).

Main Results:

• No significant group differences were observed in the timed picture-naming task.
• Children with CIs produced significantly fewer words on verbal fluency tasks compared to NH children.
• Deficits were more pronounced in phonological verbal fluency than semantic verbal fluency tasks.

Conclusions:

• Early linguistic and auditory experiences may impact lexical representations and organization in children with CIs.
• Findings suggest a need to address lexical organization, focusing on semantic and phonological richness in therapy, not just vocabulary size.
• Further research is warranted to explore underlying linguistic deficits in this population.
