Cochlear-Implant-Performance-Prediction

United States60 participantsStarted 2025-06-25

Plain-language summary

Despite improved technology, many cochlear implant (CI) recipients still struggle to understand speech in noise (SIN). Because the bottom-up acoustic signal generated by the implant is distorted relative to normal-hearing acoustic input, CI users rely more on top-down processing to decipher masked speech. To better predict outcomes for CI recipients, top-down auditory processing ability should be assessed. However, hearing impairment makes testing top-down auditory processing ability through auditory means difficult. The study aims to determine whether testing visual top-down processing can predict auditory top-down processing capability.

Inclusion Criteria: * All participants who do not fit the exclusion criteria. Exclusion Criteria: * Individuals who are not yet adults (infants, children, teenage children), * Adults unable to consent, * Adults with known impaired decision-making capacity, * Pregnant women, * Prisoners (or other detained/paroled individuals), * Students or postdoctoral trainees who are taught by or academically mentored by the Principal Investigator, in compliance with the Enrollment of Students and Trainees in Research Studies policies. * Non-fluent English speakers, Tests (specifically Scrambled Letters and QuickSIN) require proficiency in the English language. * Individuals with severe hearing impairment, Tests (specifically QuickSIN) require participants to not have trouble hearing speech. * Individuals with significant, uncorrected visual impairment.
