Lisa Bedore is chair and a professor in the Department of Communication Sciences and Disorders, where she directs the HABLA (Human Abilities in Bilingual Language Acquisition) Lab at Temple University. Bedore’s training is in the areas of communication disorders, child language acquisition, and Spanish linguistics. She is a clinically certified speech language pathologist.

The primary goal of Bedore’s research is to understand how children integrate information across linguistic domains to support language learning. Two windows into this question are bilingualism and developmental language disorders. Bilingual language learners are challenged because they have divided language experiences and they must integrate information across domains. One of Bedore’s key contributions in this area has been in her contribution to developing tools to understand children’s language experience and in the study of the relationship between patterns of language experience and language outcomes. Early in development, opportunities to hear and use each language account for a large amount of the variability in children‘s language knowledge. Over time, depth of experience comes to play a role in language outcomes. Children with developmental language disorders are inefficient language learners who do not take advantage of their language experiences to the same extent as their typically developing peers.

Bedore’s work with children with developmental language disorders has focused on documenting the patterns of grammatical difficulties across languages (Spanish, English, Mandarin) and identifying reliable clinical markers of impairment. Much of her theoretical and clinical research focuses on understanding the interface between bilingualism and developmental language disorders. Through her collaborative work in the HABLA lab she has contributed to an extensive database documenting children’s dual language skills in semantics, grammar and phonology as well as information about children’s language learning experiences. This is central to theoretical examination of predictors of bilingual language development, effective assessments developed specifically for US bilingual language learners (e.g., Bilingual English Spanish Assessment), and development of language interventions that support strong linguistic foundations for literacy.

Bedore’s research has been funded through the National Institutes of Health for over 20 years.
