Language experience and preschoolers' foreign word learning

Four-year-old English speakers (N = 48) who were monolingual, bilingual, or regularly exposed to a second language were taught what they were told were foreign labels for familiar and novel objects. When task demands were low, there was no difference in word learning among the three groups. However, when task demands were higher, bilinguals learned more words than monolingual children, and exposed children's performance fell between the two. These findings indicate that the bilingual word learning advantage seen in adults may begin as early as the preschool years.
