Abstract

The deterioration in the ability to process rapid changes in auditory input may play a primary role in the difficulty many older listeners experience perceiving speech. In young adults, perceptual skills have been found to improve with practice. However, there is very little information on the degree to which practice improves performance on perceptual tasks in older adults. Younger and older adults were trained for 10 sequential 1-hour sessions on a between-channel gap detection- task (a gap between 2-kHz and a 1-kHz noise bands). Performance on this task was assessed one day and one month after the last training session. We also tested the extent to which the benefits of training generalized to other frequencies and to the untrained ear. In addition, pre- and post-training Evoked Potential Response (ERP) measures were obtained to assess cortical changes in the response to temporal gaps induced by training.
