Abstract: In this study we examined the lexical mapping stage of auditory word recognition in children with specific language impairment (SLI). Twenty-one children with SLI, 21 children matched For chronological age (CM), and 21 vocabulary-matched (VM) children participated in a forward gating task in which they listened to successive temporal chunks of Familiar monosyllabic nouns. After each gate, children guessed the identity of the word and provided a confidence rating of their word guess. Results revealed that the children with SLI performed comparably to the CM and VM children on all seven dependent measures related to lexical mapping. The Findings were interpreted to suggest that children with SLI and their normally developing peers demonstrate a comparable lexical mapping phase (i.e., acoustic-phonetic analysis) of auditory word recognition.
