Bimodal bilinguals, fluent in a signed and a spoken language, exhibit a unique form of bilingualism because their two languages access distinct sensory-motor systems for comprehension and production.  When a bilingual’s languages are both spoken, the two languages compete for articulation (only one language can be spoken at a time), and both languages are perceived by the same perceptual system (audition).  Differences between unimodal and bimodal bilinguals have implications for how the brain might be organized to control, process, and represent two languages. Recent studies using a variety of methods illustrate what bimodal bilinguals and their ability to code-blend (to simultaneously produce a word and a sign) can tell us about language processing and the functional neural organization of language.
