This image shows the game the study participants played. The monolingual children moved the correct object about 50 percent of the time. But mere exposure to another language improved children’s ability to understand the adult’s perspective and select the correct objects. The children in the exposure group selected correctly 76 percent of the time, and the bilingual group took the adult’s perspective in the game correctly 77 percent of the time.
Young children who hear more than one language spoken at home become better communicators, a new study from University of Chicago psychologists finds. Effective communication requires the ability to take others’ perspectives.
