초록
The purpose of this study was to examine the effects of auditory-letter cue integration stimulus with and without noise environments in older adults. 25 young and 25 elderly adults with normal hearing participated. All participants completed four working memory tasks - forward digit span, backward digit span, word span and listening span were assessed at Auditory Only (AO) and Auditory Letter (AL) conditions with noise (0 dB SNR) and without noise environments. The results revealed that older adults had lower working memory capacity than young adults in all working memory tasks except digit forward span at AO condition and digit forward span, word span at AL condition without noise environment and letter-cue enhancement of older adults was higher than that of young adults. These results were interpreted that older adults had difficulty to recall speech more than young adults did, especially, under in adverse listening conditions. Also, additional sensory cue, that is letter cue, would be effective method for improvement of working memory capacity for older adults.
