Early language predicts later language in CI users

Castellanos et al. provide a longitudinal study on cochlear implant (CI) users > seven years post-implantation. Most of their test subjects were implanted as toddlers. Using the MacArthur–Bates Communicative Development Inventories (CDI), they found that “expressive language skills obtained in early toddlerhood are clinically meaningful and strongly predictive of long-term language and executive functioning outcomes in school-age and young adult CI users.” There are implications for use of the CDI as a screening tool. The background of this article is particularly interesting; the authors discuss the impact of early auditory deprivation on not just speech–language skills but executive functions as well.
