Résumé
Sign languages (SL) are natural linguistic systems comparable to spoken languages (SpL) in terms of lexical and grammatical complexity but conveyed with a different canal. SL use a visual-gestural modality while SpL use an auditory-verbal modality. Previous works have shown that neural organization for language is canal independent, and both sign and spoken language users can be similarly affected by aphasia (showing fluent and non-fluent aphasia types, anomia, agrammatism, semantic and phonological paraphasias, neologisms...) (Goldberg & Hillis, 2022; Patel 2020). While research has mainly addressed SL aphasia on a descriptive level, this study is, to our knowledge, the first to focus on intervention. Our aim is to see if the recovery mechanisms are also canal independent. To do so, we measure the evolution of naming abilities in SL users with aphasia undergoing a version of a well-established anomia therapy, the Phonological Components Analysis (Leonard et al., 2008), adapted to the signed modality using the key parameters of sign formation (Brentari, 2011), (handshape, orientation, movement, and location).
