The focus of this study was the use of grammatical morphology by Spanish-speaking preschoolers with specific language impairment (SU). Relative to both same-age peers and younger typically developing children with similar mean lengths of utterance (MLUs), the children with SU showed more limited use of several different grammatical morphemes. These limitations were most marked for noun-related morphemes such as adjective-agreement inflections and direct object clitics. Most errors on the part of children in all groups consisted of substitutions of a form that shared most but not all of the targets grammatical features (e.g., correct tense and number but incorrect person). Number errors usually involved singular forms used in plural contexts; person errors usually involved third person forms used in first person contexts. The pattern of limitations of the children with SU suggests that, for languages such as Spanish, additional factors might have to be considered in the search for clinical markers for this disorder. Implications for evaluation and treatment of language disorders in Spanish-speaking children are also discussed.
Children from bilingual backgrounds are sometimes overidentified with language impairment (LI) because educators do not have appropriate developmental expectations. At other times bilingual children are underidentified because educators wait to identify difficulties while children learn the second language. In this review we discuss data on language acquisition from several sources including cross-linguistic studies of typical first language acquisition and LI in monolingual and bilingual children. Based on this literature we discuss problems with current assessment approaches. We then propose a decision-making framework for identification of bilingual children who are at risk for LI. A key feature of this proposal is the importance of clinical markers for identification of LI.
The purpose of this study was to determine if different language measures resulted in the same classifications of language dominance and proficiency for a group of bilingual pre-kindergarteners and kindergarteners. Data were analyzed for 1029 Spanish–English bilingual pre-kindergarteners who spanned the full range of bilingual language proficiency. Parent questionnaires were used to quantify age of first exposure and current language use. Scores from a short test of semantic and morphosyntactic development in Spanish and English were used to quantify children’s performance. Some children who were in the functionally monolingual range based on interview data demonstrated minimal knowledge of their other languages when tested. Current use accounted for more of the variance in language dominance than did age of first exposure. Results indicate that at different levels of language exposure children differed in their performance on semantic and morphosyntax tasks. These patterns suggest that it may be difficult to compare the results of studies that employ different measures of language dominance and proficiency. Current use is likely to be a useful metric of bilingual development that can be used to build a comprehensive picture of child bilingualism.
Purpose-This study assesses the factors that contribute to Spanish and English language development in bilingual children.
Method-757Hispanic Pre-kindergarten and kindergarten age children completed screening tests of semantic and morphosyntactic development in Spanish and English. Parents provided information about their occupation and education as well as their children's English and Spanish exposure. Data were analyzed using zero-inflated regression models (comprising a logistic regression component and a negative binomial or Poisson component) to explore factors that contributed to children initiating L1 and L2 performance and factors that contributed to building children's knowledge.Results-Factors that were positively associated with initiating L1 and L2 performance were language input/output, free and reduced lunch, and age. Factors associated with building knowledge included age, parent education, input/output, free and reduced lunch and school district.Conclusion-Amount of language input is important as children begin to use a language, and amount of language output is important for adding knowledge to their language. Semantic development seemed to be driven more by input while morphosyntax development relied on both input and output. Clinicians who assess bilingual children should examine children's language output in their second language to better understand their levels of performance.
Several hypotheses have been offered to explain the grammatical morpheme difficulties observed in the speech of children with specific language impairment. Three of the accounts that could be evaluated in English were the focus of this study: the extended optional infinitive account, the implicit rule deficit account, and the surface account. Preschoolers with specific language impairment, a group of age controls, and a group of younger children matched for mean length of utterance were evaluated in their use of several theory-relevant grammatical morphemes. The findings revealed advantages for both the surface and extended optional infinitive hypotheses. In contrast, a test of the predictions based on the implicit rule deficit account suggested that the children studied here were not experiencing a deficit of this type.
