Updating ability reduces the negative effect of noise on memory of speech for persons with age-related hearing loss
2014 (English)Manuscript (preprint) (Other academic)
Background noise makes listening more cognitively demanding, especially for persons with hearing impairment, and this seems to affect memory encoding. In the present study, we investigated free recall of highly intelligible spoken two-digit numbers presented with and without noise and with and without visual cues. Twenty young adults with normal hearing took part in Experiment 1 and twenty-four older adults with hearing loss in Experiment 2. Amplification compensated for loss of audibility. The young adults performed better than the older adults with hearing loss. Background noise reduced performance to a similar extent in both groups probably due to poorer long-term memory encoding. However, older adults with hearing loss who had better executive skills showed better long term memory encoding. Visual cues improved performance for both groups but more for the young adults. The older adults with hearing impairment seemed to engage a range of cognitive skills to perform the free recall task.
