Codeswitching in Bilingual Aphasia

The purpose of this project is to examine how Spanish-English bilingual adults with aphasia switch between languages.  Typically, codeswitching studies include healthy participants (e.g., Branzi, Calabria, Boscarino, Costa, 2016; Calabria, Branzi, Marne, Hernandez, Costa, 2013; Prior & Gollan, 2011). Results show that switch trials evoke longer response times compared to non-switch trials and based on language experience, switching costs and mixing costs may also be affected.

In this study, bilingual adults with aphasia are asked to identify associations for within language word-pairs.  Based on previous work in the lab, we expect bilingual adults with aphasia to be slower on switch vs. non-switch trials; however, outcomes regarding switching and mixing costs are unclear.
