Grammaticality Judgments of Tense and Agreement by Children With and Without Developmental Language Disorder Across Dialects of English.

purposeWithin General American English (GAE), the grammar weaknesses of children with developmental language disorder (DLD) have been documented with many tasks, including grammaticality judgments. Recently, Vaughn et al. replicated this finding with a judgment task targeting tense and agreement (T/A) structures for children who spoke African American English (AAE), a dialect that contains a greater variety of T/A forms than GAE. In the current study, we further tested this finding for children who spoke Southern White English (SWE), another dialect that contains a greater variety of T/A forms than GAE but less variety than AAE. Then, combining the SWE and AAE data, we explored the effects of a child's dialect, clinical group, and production of T/A forms on the children's judgments.

methodThe data were from 88 SWE-speaking children (DLD,

conclusionsChildren with DLD across dialects of English present grammar difficulties that affect their ability to make judgments about sentences. More cross-dialectal research is needed to better understand the grammatical weaknesses of childhood DLD, especially for structures such as verbal -
