Cortical Correlates of Binaural Temporal Processing Deficits in Older Adults.

ABSTRACT:

Objectives

This study was designed to evaluate binaural temporal processing in young and older adults using a binaural masking level difference (BMLD) paradigm. Using behavioral and electrophysiological measures within the same listeners, a series of stimulus manipulations was used to evaluate the relative contribution of binaural temporal fine-structure and temporal envelope cues. We evaluated the hypotheses that age-related declines in the BMLD task would be more strongly associated with temporal fine-structure than envelope cues and that age-related declines in behavioral measures would be correlated with cortical auditory evoked potential (CAEP) measures.

Design

Thirty adults participated in the study, including 10 young normal-hearing, 10 older normal-hearing, and 10 ol
