Jesse and Stephanie are getting ready to have their first son, and they are interested in teaching him both of their native languages (Spanish and English) from his earliest years. They are concerned, however,
that if they teach both languages that the child will confuse the two and will not be able to distinguish between them as he gets older. What does research noted in your text have to say about bilingualism in children? a. Research has found that bilingualism is not truly possible in children before they hit their adolescent years, so the parents would be best advised to choose one language to teach their son. b. Because of different brain areas that control language development in boys and girls, the parents' concerns would only be valid if they were having a daughter. c. Children who are raised with only one language develop much better fluency in that language than children who are raised with two or more languages, so the parents' concerns are very valid. d. Children who are bilingual seem to be able to keep two or more vocabularies separate, so the parents' concerns are not an issue.
