Strengthening the semantic verb network in multilingual people with aphasia: within- and cross-language treatment effects*

Abstract In multilingual people, semantic knowledge is predominantly shared across languages. Providing semantic-focused treatment to people with aphasia has been posited strengthen connectivity within association cortices that subserve knowledge. such should result in within- and cross-language generalisation all languages, although not equally. We investigated effects two participants who received verb-based pre-stroke highly proficient compared patterns finding after the less-impaired, pre-morbidly more-proficient first-acquired language (L1). This observation supports theory greater between lexicon of a L1 system than less-proficient later-acquired language. Our findings could also be explained by both Competing Mechanisms Theory lingering suppression.
