Receptive and Expressive Semantics: Does Bilingual Experience Matter?

The short answer is yes. But, the longer answer is more interesting I think. It’s well-known that we can understand more words than we can express. Generally though, there are strong associations between receptive and expressive language, the more words you understand the more words you can express. We see normal receptive-expressive gaps in early language development, later development, as well as in mature learners. As adults, there are words that we can recognize by context in reading for example, but don’t use them expressively or don’t consistently recall them. On standardized tests however, these inherent differences between the two kinds of tasks are controlled. We can compare performance on expressive and receptive tasks through use of standardized scores often using a mean of 100 and a standard deviation of 15. Large receptive-expressive discrepancies where receptive knowledge is much stronger than expressive knowledge can be an indicator of language impairment. How does this work in bilinguals?
