Effects Of Aging And Spectral Shaping On The Sub-Cortical (Brainstem) Differentiation Of Contrastive Stop Consonants, Dania A. Rishiq
Theses and Dissertations (ETD)
Purpose: The objectives of this dissertation are to: (1) evaluate the influence of aging on the sub-cortical (brainstem) differentiation of voiced stop consonants (i.e. /b-d-g/); (2) determine whether potential aging deficits at the brainstem level influence behavioral identification of the /b-d-g/ stimuli, (3) investigate whether spectral shaping diminishes any aging impairments at the brainstem level; and (4) if so, whether minimizing these deficits improves the behavioral identification of the speech stimuli.
Subjects: Behavioral and electrophysiological responses were collected from 11 older adults (> 50 years old) with near-normal to normal hearing and were compared to those of 16 normal-hearing younger …
