What Do Children with Specific Language Impairment Do with Multiple Forms of "DO"?

Purpose: This study was designed to examine the early usage patterns of multiple grammatical functions of "DO" in children with and without specific language impairment (SLI). Children's use of this plurifunctional form is informative for evaluation of theoretical accounts of the deficit in SLI. Method: Spontaneous uses of multiple functions of "DO" were analyzed in language samples from 89 children: 37 children with SLI, ages 5;0-5;6 (years;months); 37 age-equivalent children; and 15 language-equivalent children, ages 2;8-4;10. Proportion correct and types of errors produced were analyzed for each function of "DO." Results: Children with SLI had significantly lower levels of proportion correct auxiliary "DO" use compared to both control groups, with omissions of the "DO" form as the primary error type. Children with SLI had near-ceiling performance on lexical "DO" and elliptical "DO," similar to both control groups. Conclusions: Plurifunctionality is not problematic: Children acquire each function of "DO" separately. Grammatical properties of the function, rather than surface properties of the form, dictate whether children with SLI will have difficulty using the word. Overall, these results support the extended optional infinitive account of SLI and the use of auxiliary "DO" omissions as part of a clinical marker for SLI.
