The idea behind the experiment is to see what qualities kids see as innate. Is the language that a person speaks innate, or is it learned? Is the sound that an animal makes innate, or is it learned?
The implications could be quite profound. I quote the final four paragraphs here:
“Both monolinguals and second language learners showed some errors in their thinking, but each group made different kinds of mistakes. Monolinguals were more likely to think that everything is innate, while bilinguals were more likely to think that everything is learned,” says Byers-Heinlein.
“Children’s systematic errors are really interesting to psychologists, because they help us understand the process of development. Our results provide a striking demonstration that everyday experience in one domain — language learning — can alter children’s beliefs about a wide range of domains, reducing children’s essentialist biases.”
The study has important social implications because adults who hold stronger essentialist beliefs are more likely to endorse stereotypes and prejudiced attitudes.
“Our finding that bilingualism reduces essentialist beliefs raises the possibility that early second language education could be used to promote the acceptance of human social and physical diversity,” says Byers-Heinlein.
I’ve often wondered what would happen to racism in the world if every child born was interracial. The next best thing? If every child is multilingual.
I hope more research is done in this field.
