Lexical access impairment vs. language control impairment in bilingual aphasia

Bilingual persons with aphasia have a unique language deficit characterized by deficits in lexical access (i.e., aphasia) and language control (i.e., the ability to speak in one language without interruption from the other language). If bilingual persons with aphasia cannot name an object, is that due to deficits in lexical access, language control or a combination of the two? Currently this distinction is unknown and presents a challenge to intervention. In order to develop evidence-based treatment methods for this population, the relationship between aphasia and language control must be identified. This project explores the relationship between language control and lexical access in Spanish-English bilingual adults with aphasia.

We are currently recruiting Spanish-English adults with aphasia. Individuals can be balanced or unbalanced bilinguals with any type of aphasia. If interested in learning more, please contact Dr. Teresa Gray at graymatterlaboratory@gmail.com.
