Purpose: This study examines the utility of Video-Implemented Script Training for Aphasia (VISTA) for improving speech production and fluency in a Spanish-English bilingual speaker with aphasia. Method: In this single-subject, multiple-baseline intervention study, VISTA was utilized to facilitate fluent and intelligible speech through training…

Although a "semantic receptive-expressive gap" appears to be a universal feature of early bilingualism, little is known about its development. We sought to determine if the magnitude of the discrepancy between receptive and expressive standard scores changed over time in bilingual children's two languages. In this longitudinal study,…

Purpose: Bilinguals tend to produce cognates (e.g., "telephone" in English and "teléfono" in Spanish) more accurately than they produce noncognates ("table"/"mesa"). We tested whether the same holds for bilingual children with specific language impairment (SLI). Method: Participants included Spanish-English…

We explore the classification accuracy of a parent and teacher report measure, the Inventory to Assess Language Knowledge (ITALK), to screen for developmental language disorder (DLD) in bilingual children. Participants were 120 Spanish-English bilingual children with typical development (TD) and 19 bilingual children with DLD, ranging in age from…

Purpose: The study examines the extent of convergence of semantic category members in Spanish-English bilingual children with reference to adults using a semantic fluency task. Method: Thirty-seven children with developmental language disorder (DLD), matched pairwise with 37 typically developing (TD) children in the age range of 7;0-9;11…

Theories of how language works have shifted from rule-like competence accounts to more skill-like incremental learning accounts. Under these, people acquire language incrementally, through practice, and may even lose it incrementally as they acquire competing mappings. Incremental learning implies that (1) a bilingual's abilities in their…

Research has investigated how lexical-semantic and participant factors impact word learning in young children and adults. However, limited information pertaining to expressive vocabulary development exists for school-aged bilinguals--particularly those with developmental language disorder (DLD). Cross-linguistic differences in the semantic…

Purpose: The differential diagnosis of developmental language disorder (DLD) in bilingual children represents a unique challenge due to their distributed language exposure and knowledge. The current evidence indicates that dual-language testing yields the most accurate classification of DLD among bilinguals, but there are limited personnel and…

This study sought to scaffold administration performance of a standardized bilingual screener to sufficient levels of accuracy for data collection using principles of Cognitive Load Theory by managing task complexity when training pre-service clinicians. Before training administration skills, two students were given copies of the manual for the…

Purpose: Using a blocked cyclic picture-naming task, we compared accuracy and error patterns across languages for Spanish-English bilingual children with and without developmental language disorder (DLD). Method: Pictured stimuli were manipulated for semantic similarity across two (Same and Mixed) category contexts. Children's productions were…

Purpose: This study examines English performance on a set of 11 grammatical forms in Spanish-English bilingual, school-age children in order to understand how item difficulty of grammatical constructions helps correctly classify language impairment (LI) from expected variability in second language acquisition when taking into account linguistic…

Children with Developmental language disorder (DLD) have particular difficulty learning language despite otherwise general normal development. When school age bilingual children struggle with language, a common question is if the difficulties they present reflect lack of ability or lack of language experience. To address the question of…

Purpose: This study examined the use of African American English (AAE) among a group of young Latinx bilingual children and the accuracy of the English Morphosyntax subtest of the Bilingual English-Spanish Assessment (BESA) in classifying these children with and without developmental language disorder (DLD). Method: Children (N = 81) between the…

Purpose: This study examined the effects of single-language and conceptual scoring on the vocabulary performance of bilingual children with and without specific language impairment. We assessed classification accuracy across 3 scoring methods. Method: Participants included Spanish-English bilingual children (N = 247) aged 5;1 (years;months) to…

Background: Significant progress has been made in the identification of language impairment in children are bilingual. Bilingual children's vocabulary knowledge may be distributed across languages. Thus, when testing bilingual children it is difficult to know how to weigh each language for diagnostic purposes. Even when conceptual scoring is used…
