Also, monolinguals performed better than bilinguals on verbal fluency in the study. Kirkpatrick asserts that monolinguals are at a disadvantage to bilinguals in the international job market. There is a significant difference in the amount of TOTs experienced by monolinguals and bilinguals. Similar effects have been found in lifelong elderly bilinguals and simultaneous bilingual children. Language comprehension research on bilinguals used fMRI techniques. Often simultaneous bilinguals are more proficient in their languages than sequential bilinguals. Equally proficient bilinguals use working memory more than bilinguals who have unequal proficiency. Children acquiring two languages natively from these early years are called simultaneous bilinguals. Children who acquire two languages from birth are called simultaneous bilinguals. Children acquiring two languages in this way are called simultaneous bilinguals. The rest of them were bilinguals, French Canadians or allophones (Norwegian-speaking only). Monolinguals also access words more often than bilinguals in a target language. Even in the case of simultaneous bilinguals, one language usually dominates over the other. This amounts to 25.7% Basque bilinguals overall, 15.4% passive speakers, and 58.9% non-speakers. Today there are 751 500 bilinguals and 434 000 passive speakers.
