From The New York Times, the Bilingual Advantage. Ellen saw that there was a big difference in the way monolingual and bilingual children processed language.
Q. How did you begin studying bilingualism?
A. You know, I didn’t start trying to find out whether bilingualism was bad or good. I did my doctorate in psychology: on how children acquire language. When I finished graduate school, in 1976, there was a job shortage in Canada for Ph.D.’s. The only position I found was with a research project studying second language acquisition in school children. It wasn’t my area. But it was close enough.
As a psychologist, I brought neuroscience questions to the study, like “How does the acquisition of a second language change thought?” It was these types of questions that naturally led to the bilingualism research. The way research works is, it takes you down a road. You then follow that road.
Q. So what exactly did you find on this unexpected road?
A. As we did our research, you could see there was a big difference in the way monolingual and bilingual children processed language. We found that if you gave 5- and 6-year-olds language problems to solve, monolingual and bilingual children knew, pretty much, the same amount of language.
But on one question, there was a difference. We asked all the children if a certain illogical sentence was grammatically correct: “Apples grow on noses.” The monolingual children couldn’t answer. They’d say, “That’s silly” and they’d stall. But the bilingual children would say, in their own words, “It’s silly, but it’s grammatically correct.” The bilinguals, we found, manifested a cognitive system with the ability to attend to important information and ignore the less important.
