Nonword repetitions of children with specific language impairment: Exploration of some explanations for their inaccuracies

Abstract

To examine possible explanations of the reported inaccuracies of children with specific language impairment (SLI) on nonword repetition, we compared the repetitions of 54 children with SLI and their peers in terms of number and type of error as well as latency and duration of response. We found no evidence of differences between the groups in auditory discrimination or response processes, but we did find some evidence suggesting differences in either the formation or storage of phonological representations in working memory. Because repetition accuracy was significantly correlated with expressive, but not receptive, measures of language, we hypothesized that the problem lay with the nature of phonological representations in working memory and not with the ability to hold phonological information in working memory.
