Purpose: In this reply, we respond to comments on our article "Tracking the Growth of Tense and Agreement in Children With Specific Language Impairment: Differences Between Measures of Accuracy, Diversity, and Productivity." Conclusion: The finite verb morphology composite can be disproportionately affected by frequently occurring…

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.…

Purpose: Composite measures of children's use of tense and agreement morphology differ in their emphasis on accuracy, diversity, or productivity, yet little is known about how these different measures change over time. An understanding of these differences is especially important for the study of children with specific language impairment, given…

Purpose: P. A. Hadley and H. Short (2005) developed a set of measures designed to assess the emerging diversity and productivity of tense and agreement (T/A) morpheme use by 2-year-olds. The authors extended 2 of these measures to the preschool years to evaluate their utility in distinguishing children with specific language impairment (SLI) from…

Purpose: Hungarian is a null-subject language with both agglutinating and fusional elements in its verb inflection system, and agreement between the verb and object as well as between the verb and subject. These characteristics make this language a good test case for alternative accounts of the grammatical deficits of children with language…

The aim of this study was to uncover factors accounting for the ability of children with specific language impairment (SLI) to learn agreement morphemes in intervention. Twenty-five children with SLI who participated in a six-month intervention program focused on teaching third person singular -s or auxiliary "is"/"are"/"was" showed a wide range…

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…

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…

This paper reports on two studies of finite verb use to determine whether children with specific language impairments, who use grammatical morphemes less than typical children matched for mean length of utterance (MLU), produce other language details more frequently. The paper concluded that offsetting effects are not necessary in principle, given…

This study examined the influence of argument-MA-structure complexity on the omission of auxiliary "be" verbs in 30 children with specific language impairment (SLI). Results indicated that the children with SLI and controls matched for mean length of utterance were more likely to omit the auxiliary forms when attempting sentences with greater…

Evaluation of the grammatical morphology used by 50 preschool children with specific language impairment as a function of their lexical diversity found their use of finite-verb morphology (based on number of different verbs used) and noun-related morphology lagged behind expectations in comparison to a group of normally developing preschoolers.…

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…

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…

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.…
