Code-switching patterns and inhibitory control in bilinguals with traumatic brain injury
MetadataShow full item record
Three case studies of code-switching in Spanish-English bilingual speakers with traumatic brain injury were conducted to investigate the relationship between executive functioning and language inhibition. Participants conversed in three language contexts: monolingual English, monolingual Spanish, and bilingual (both English and Spanish). Patterns of code-switching in participants with TBI and the influence of communication partner language choice during the bilingual context are described. Two participants with executive functioning deficits produced unconventional code-switching with the use of their non-dominant language. No code-switching occurred with the use of their dominant language. One participant with TBI had co-morbid aphasia and produced frequent unconventional code-switching with the use of his dominant language and no code-switching with the use of his non-dominant language. Results are discussed with reference to hypotheses of language interference, the relationship of cognitive-control between language use and abilities, linguistic activation, implications for therapy, and directions for future research.
