The Nonword Repetition Task (NRT) is considered to be a less-biased language measure for children from cultural minority groups. In the current study, we examined NRT performance of 50 at-risk, preschool-age children who spoke African American English (AAE). In addition to the NRT, measures included AAE dialect density and several standardised language tests. The primary aim was to determine significant contributors to NRT performance. We hypothesised that the language measures would significantly contribute to NRT performance while dialect density would be an insignificant contributor. Contrary to our predictions, dialect density was a unique and significant predictor of NRT performance (in addition to phonological awareness), while the language measures were not significant predictors. The current findings cast doubt on categorising the NRT as a less-biased language assessment for AAE-speaking preschoolers; however, the NRT may have potential as a screener for identifying preschoolers at risk for delays in literacy acquisition.

Sixteen-year-olds with specific language impairment (SLI), nonspecific language impairment (NLI), and those showing typical language development (TD) responded to target words in sentences that were either grammatical or contained a grammatical error immediately before the target word. The TD participants showed the expected slower response times (RTs) when errors preceded the target word, regardless of error type. The SLI and NLI groups also showed the expected slowing, except when the error type involved the omission of a tense/agreement inflection. This response pattern mirrored an early developmental period of alternating between using and omitting tense/agreement inflections that is characteristic of SLI and NLI. The findings could not be readily attributed to factors such as insensitivity to omissions in general or insensitivity to the particular phonetic forms used to mark tense/agreement. The observed response pattern may represent continued difficulty with tense/agreement morphology that persists in subtle form into adolescence.
