N2 - Purpose: We examined the effects of vocabulary, lexical Results: Children from both groups with larger vocabularies characteristics (age of acquisition and phonotactic showedbetterperformancethanchildrenwithsmaller probability), and auditory access (aided audibility and vocabularies on nonwords and late-acquired words but not daily hearing aid [HA] use) on speech perception skills in early-acquired words. Overall, children with HAs showed children with HAs. poorer performance than children with NH. Auditory access Method: Participants included 24 children with HAs and was not associated with speech perception for the children 25 children with normal hearing (NH), ages 5–12 years. with HAs. Groups were matched on age, expressive and receptive Conclusions: Children with HAs show deficits in sensitivity vocabulary, articulation, and nonverbal working memory. to phonological structure but appear to take advantage of Participants repeated monosyllabic words and nonwords in vocabulary skills to support speech perception in the same noise.
