Prof. Castro’s research focuses on the precision rehabilitation of anomia, or word retrieval impairment. She takes a multi-pronged approach by modeling how words are organized in and retrieved from memory, maximizing treatment designs to increase acquisition of trained words and generalization of treatment to untrained words and contexts, and understanding how clinicial decisions are made for specific clients receiving anoma treatment.
