The Impact of Vocabulary Breadth and Depth on Bilingual Comprehension
A recent study conducted by researchers in the United States and Canada has found that bilingual children demonstrate greater comprehension of language than monolingual children, and the key to their success is in their breadth and depth of vocabulary. The study, published in the Journal of Experimental Child Psychology, examined the language comprehension of both monolingual and bilingual children between the ages of six and nine. The researchers found that bilingual children had greater breadth and depth of vocabulary because they were exposed to two distinct languages, which allowed them to think more deeply about the meanings of words. This greater understanding of language enabled them to better comprehend complex stories. This finding suggests that bilingualism may offer children cognitive advantages in the area of language comprehension, and may potentially benefit their academic performance.
