Neurocognitive Processes in Deaf Children with Cochlear Implants (R01 DC009581)

This new research project focuses on the neurocognitive processes underlying speech and language outcomes in prelingually deaf children following cochlear implantation. Past research on cochlear implants has been narrowly focused on speech and language outcomes and efficacy of cochlear implantation as a medical treatment for profound hearing loss. The primary objective of this research project is to demonstrate that domain-general neurocognitive processes related to executive functioning, such as working memory, fluency-speed, concentration-inhibition and organization-integration skills, are strongly associated with traditional clinical speech and language outcome measures. These executive function/cognitive control processes involve the global coordination, integration and functional connectivity of multiple underlying brain systems used in speech perception, production and spoken language processing.
