Semantic processing in bilingual people with aphasia: An eye-tracking study examining cross-language semantic facilitation and interference.

About the Author: Sophie Blankenheim conducted her master’s thesis on this work under the supervision of Maria Varkanitsa Summary Bilingual lexical processing involves simultaneous activation of both languages, with encountering a word in one language priming the equivalent word in the other. Previous research on healthy individuals has shown that naming responses are slowed down […]

Evolution of word production errors after typicality-based semantic naming treatment in individuals with aphasia

Authors: Ran Li, Natalie Gilmore, Mia O’Connell, Swathi Kiran Q&A with Ran Li What is this paper about and why are the results important? This study implemented an error coding scale to assess changes in word production errors following a semantic-based naming therapy in individuals with chronic aphasia. It provides insights into the linguistic mechanisms that […]
