Children with developmental language disorder (DLD) have significant deficits in language ability that cannot be attributed to neurological damage, hearing impairment, or intellectual disability. The symptoms displayed by children with DLD differ across languages. In English, DLD is often marked by severe difficulties acquiring verb inflection.…

Krok, Windi C.; Leonard, Laurence B. – Journal of Speech, Language, and Hearing Research, 2018
Purpose: This study was specifically designed to examine how verb variability and verb overlap in a morphosyntactic priming task affect typically developing children's use and generalization of auxiliary IS. Method: Forty typically developing 2- to 3-year-old native English-speaking children with inconsistent auxiliary IS production were primed…

Krok, Windi C.; Leonard, Laurence B. – Journal of Speech, Language, and Hearing Research, 2015
Purpose: This study examined the extent to which children with specific language impairment (SLI) across Germanic languages differ from their typically developing (TD) peers in the use of past tense morphology. Method: A systematic literature search identified empirical studies examining regular and/or irregular past tense production by English…

Polite, Elgustus J.; Leonard, Laurence B. – Child Language Teaching and Therapy, 2007
Children with specific language impairment (SLI) often have extraordinary difficulty in the use of tense and agreement morphemes. Because spontaneous speech samples may not provide a sufficient number of obligatory contexts for these morphemes, structured probe items are often employed. However, these usually emphasize actions that can be readily…

Leonard, Laurence B.; Deevy, Patricia; Miller, Carol A.; Charest, Monique; Kurtz, Robert; Rauf, Leila – Journal of Child Language, 2003
Children with specific language impairment (SLI) have well-documented problems in the use of tense-related grammatical morphemes. However, in English, tense often overlaps with aspect and modality. In this study, 15 children with SLI (mean age 5;2) and two groups of 15 typically developing children (mean ages 3;6 and 5;3) were compared in terms of…

Leonard, Laurence B.; Hansson, Kristina; Nettelbladt, Ulrike; Deevy, Patricia – Language Acquisition, 2004
We report a cross-linguistic investigation of English-and Swedish-speaking children with specific language impairment (SLI) in an attempt to determine whether Wexler's (1998; 2003) (Extended) Unique Checking Constraint (EUCC) can account for the grammatical profiles of these groups of children. In Study 1, a group of Swedish-speaking preschoolers…
