The LSU research team aims to identify clinical markers of children with Specific Language Impairment in non-traditional dialects, such as African American English and Southern White English. They hope to develop tools that can be used in Louisiana classrooms to assist speech language pathologists and educators.
The MOSAIC program is a four-year training initiative for graduate students to work with immigrant children learning English as a second language. The program addresses inadequate training of speech-language pathologists to diagnose communication disorders in multilingual children, targeting rural states with high numbers of ESL learners.
A new parent questionnaire, Language Use Inventory (LUI), has been developed to evaluate language skills in children with autism. The LUI assesses pragmatic language development, which is critical for effective communication in everyday interactions.
A Northwestern University study found that bilingual participants mastered nearly twice the number of words as monolinguals when learning an invented language. The research suggests that early exposure to two languages carries far-reaching benefits, making bilingual individuals better language learners in general.
