Direct linkLeonard, Laurence B.; Deevy, Patricia; Horvath, Sabrina; Christ, Sharon L.; Karpicke, Jeffrey; Kueser, Justin B. – Journal of Speech, Language, and Hearing Research, 2023
Purpose: Children with developmental language disorder (DLD) have well-documented verb learning difficulties. In this study, we asked whether the inclusion of retrieval practice during the learning period would facilitate these children's verb learning relative to a similar procedure that provided no retrieval opportunities. Method: Eleven…

Weil, Lisa Wisman; Leonard, Laurence B. – Journal of Child Language, 2017
This study employed a paired priming paradigm to ask whether input features influence a child's propensity to use non-nominative versus nominative case in subject position, and to use non-nominative forms even when verbs are marked for agreement. Thirty English-speaking children (ages 2;6 to 3;7) heard sentences with pronouns that had…

Finneran, Denise A.; Leonard, Laurence B. – Journal of Speech, Language, and Hearing Research, 2010
Purpose: To examine the role of linguistic input in how young, typically developing children use the 3rd person singular -"s" (3S) inflection. Method: Novel verbs were presented to 16 young children in either 3S contexts (e.g., "The tiger heens") or nonfinite (NF) contexts (e.g., "Will the tiger heen?"). The input was further manipulated for…

Peer reviewedHsieh, Li; Leonard, Laurence B.; Swanson, Lori – Journal of Child Language, 1999
Examined input frequency, sentence position, and duration as contributing factors to grammatical inflections. In parents' conversations with and stories aimed at young children, noun plural inflections were more frequent than third singular verb inflections, especially in sentence-final position. Analysis of four mothers' speech when reading…

Owen, Amanda J.; Leonard, Laurence B. – Journal of Speech, Language, and Hearing Research, 2006
The purpose of this study was to explore whether 13 children with specific language impairment (SLI; ages 5;1-8;0 [years;months]) were as proficient as typically developing age- and vocabulary-matched children in the production of finite and nonfinite complement clauses. Preschool children with SLI have marked difficulties with verb-related…

Peer reviewedLoeb, Diane Frome; Leonard, Laurence B. – Journal of Speech and Hearing Research, 1991
The study found that eight specifically language-impaired children (ages four and five) were more limited than eight normally developing children (ages two and three, matched for mean utterance length) in the use of both subject case marking and verb morphology. A relationship between the two types of usage was found in both groups of children.…
