The Role of Auditory Experience in the Neurocognitive Systems for Everyday and Effortful Listening
Current models of auditory cognition suggest that cognitive resources for processing degraded acoustic information are limited, creating a trade-off between effort and comprehension. Indeed, everyday listening frequently occurs under a wide range of inescapable suboptimal and adverse conditions, challenges which are exacerbated by reduced hearing acuity and the use of imperfect hearing amplification and prosthetic devices.
In this cognitive neuroscience experiment using optical neuroimaging, we assess:
Advancing these scientific questions allows us to better understand the complex nature of neuroplasticity and early-life sensitive windows for language processing. It will ultimately inform us of the underlying cognitive mechanisms that play a role in spoken language outcomes for hearing aid and cochlear implant users.
This work has profound implications for transformative translational impacts across several domains, such as educational practice and policy, aural (re)habilitation clinical practice approaches, and assessment of clinical health outcomes.
Ultimately, this work will advance several scientific and societal questions regarding the role of deafness mediated by hearing technologies in certain cognitive functions, such as language processing and comprehension, effort, stress, and fatigue. These advancements could improve overall health and quality of life outcomes in those with hearing loss.
