This research examined how linguistic differences between African American English (AAE) and Mainstream American English (MAE) impact how children process sentences and learn new information. The central hypothesis of this dissertation is that these linguistic differences adversely impact how AAE-speaking children use contrastive inflectional verb…

Purpose: We compared copula and auxiliary verb BE use by African American English-speaking children with and without a creole heritage, using Gullah/Geechee as the creole criterion, to determine if differences exist, the nature of the differences, and the impact of the differences on interpretations of ability. Method: Data came from 38 children,…

Purpose: Using data from children who spoke various nonmainstream dialects of English and who were classified as either children with specific language impairment (SLI) or typically developing (TD) children, we examined children's marking of infinitival TO by their dialect and clinical status. Method: The data came from 180 kindergartners (91…

Purpose: This study examined African American English--speaking children's use of BE, DO, and modal auxiliaries. Method: The data were based on language samples obtained from 48 three-year-olds. Analyses examined rates of marking by auxiliary type, auxiliary surface form, succeeding element, and syntactic construction and by a number of child…

Purpose: To examine 3 forms ("am," "is," "are") of auxiliary BE production by African American English (AAE)-speaking children with and without specific language impairment (SLI). Method: Thirty AAE speakers participated: 10 six-year-olds with SLI, 10 age-matched controls, and 10 language-matched controls. BE production was examined through…

In discussions of cross-linguistic influence (also known as language transfer), the focus is usually on the influence of a particular structure in a particular instance of language contact, for instance, the negative transfer of serial verbs by Vietnamese learners of English: "She has managed to rise the kite fly over the tallest…

The study examined children's use of verbal -s marking (e.g., he "walks") in two nonmainstream dialects of English, African American English (AAE), and Southern White English (SWE). Verbal -s marking was of interest because there are gaps in the literature about the nature of this structure within and across typically developing children…

Purpose: To examine lexical knowledge in children through a fast mapping task. Method: This study compared the performance of 60 African American English-speaking and general American English-speaking children between the ages of 4 and 6 years. They were presented with a comprehension task involving the fast mapping of novel verbs in 4 different…

Purpose: To investigate children's performance on a fast mapping task. Possible effects across age, dialect group, and clinical status were explored. Method: Participants between the ages of 4 and 9 saw a series of pictured events and heard novel verbs. The novel verbs were in intransitive, transitive, dative, and complement syntactic frames or…

The production of third-person /s/ on English verbs seems to be ahead of comprehension. Mainstream American English (MAE) is contrasted with African American English (AAE), in which /s/ is rarely supplied. Two studies explored what information children get solely from /s/ on the end of a verb. Sixty-five MAE- and 65 AAE-speaking four- to…

The extension of the progressive aspect to stative verbs has been identified as a characteristic feature of New Varieties of English across the world, including the English of black South Africans (BSAfE). This paper examines the use of the progressive aspect in BSAfE, by doing a comparative analysis of three corpora of argumentative student…
