Background: Turkish has a rich system of noun suffixes, and although its complex suffixation system may seem daunting, it can actually present a learning opportunity for children. Despite its unique features, Turkish has not been studied extensively, especially in the case of children with language deficits, such as developmental language disorder…

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…

We tested four predictions based on the assumption that optional infinitives can be attributed to properties of the input whereby children inappropriately extract non-finite subject-verb sequences (e.g. "the girl run") from larger input utterances (e.g. "Does the girl run?" "Let's watch the girl run"). Thirty children…

Purpose: Our purpose was to test the competing sources of input (CSI) hypothesis by evaluating an intervention based on its principles. This hypothesis proposes that children's use of main verbs without tense is the result of their treating certain sentence types in the input (e.g., "Was 'she laughing'?") as models for declaratives…

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…

Purpose: The author presents a tutorial on structural priming and its relevance to the study of grammatical development and language intervention. Method: The findings from structural priming studies are examined from the standpoint of the types of changes that occur in participants' language use, the contexts in which these changes occur, and the…

Background: Many school-age children with specific language impairment produce sentences that appear to conform to the adult grammar. It may be premature to conclude from this, however, that their language formulation ability is age appropriate. Aims: To determine whether a more subtle measure of language use, speech disruptions during sentence…

Purpose: Children with specific language impairment (SLI) often fail to produce past tense forms in obligatory contexts, although the factors affecting such inconsistency are not well understood. This study examined the influence of accompanying temporal adverbials (e.g., "just, already") on the past tense production of these children. Method:…

Describes early word usage in four children aged 1.6 to 1.9. The research investigated the children's use of words whose referents are unknown to them. (Author/AM)

Judgments of utterance appropriateness were examined in three, four, five, and six year olds to examine bases for these judgments in a variety of social contexts. The judgments of the six year olds more closely resembled those of a group of adults, but their judgments were not yet free of some of the factors operative for the younger children.…

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…

Reports three studies concerning individual differences in children's use of consonants during early phonological development. The findings indicate that these differences fall within a predictable range, that the linguistic environment cannot account for several of them, and that they are partly due to variations in the choice of lexical items.…

Analysis of the spontaneous speech of English- and Italian-speaking children with specific language impairment indicated that word-final consonants adversely influenced Italian subjects' tendency to use articles. There was no evidence of syntactic differences between the language groups. (Author/CB)

Twenty-five Italian-speaking children (ages 4 to 7) with specific language impairments were compared to younger control children in their use of auxiliary verbs, pronominal clitics, infinitives, present-tense verbal inflections, and articles. Differences favoring the control children were found for those morphemes that required the production of…

Children with specific language impairments (eight learning Italian, eight learning English as a first language) were studied for grammatical deficits. Italian-speakers used noun inflections, verb inflections, copula forms more than English-speaking counterparts, matched by utterance length. Articles were used similarly. Results were consistent…
