Immigration, international trade, multicultural families: these are all
situations where one might observe incidences of multilingualism
today. Multilingual speakers outnumber monolingual speakers
worldwide. A clear understanding the neural components of this
phenomenon could have numerous educational and cultural
implications. In this study, I tested the hypothesis that proficiency
will have a significant effect on the extent of hemispheric language
dominance of second language. It was additionally hypothesized that
within the left hemisphere, a higher level of activation would be
present for second language. Transcranial Doppler sonography was
sampled in 10 healthy, right-handed, volunteers who had been
exposed to both the French and English languages. There were no
statistically significant effects of language proficiency on
hemispheric language dominance. There were no statistically
significant differences in extent of activation for second language. |
