ClinConnect Summary

This research aims to understand age-related temporal processing in older cochlear-implant (CI) users. The overall objective is to disentangle the peripheral and central contributions to age-related temporal processing deficits in this population. The central hypothesis is that age-related speech perception deficits are explained by unique contributions from peripheral and central auditory functions, significantly affecting outcomes in older CI users.

The central hypothesis will be tested by determining (1) the extent to which temporal processing of simple signals from single-electrode sti...
