Bilingual children and communication disorders: a 30-year research retrospective.

We present a review of the empirical literature at the intersection of bilingualism and pediatric communication disorders. A computer search of six electronic databases was done to identify studies published in English since 1950 that directly investigated some aspect of speech, language, or cognitive performance in developing bilinguals and children with communication impairments. The computer search yielded 116 non-duplicated articles, the first published in 1978.
