Prof. Castro’s research focuses on word retrieval in aging adults and adults with language impairments (e.g., aphasia, dementia), with a particular focus on how words are organized in memory. Her research uses behavioral studies and computational modeling, with an important focus on translating theories to clinical practice (e.g., maximizing aphasia treatment outcomes).
