| ABSTRACT |
|
The purpose of present study was to investigate aging effects on frequency pattern recognition in a population in Korean by using pitch
pattern tests. Frequency pattern test has been used to measure central auditory function that is sensitive to lesions in either hemisphere
or interhemisphere. A wealth of experimental evidence suggests that frequency pattern recognition degrades with aging, and that
performance deficits are more severe in verbal than in humming modes of responses (Bellis & Wilber, 2001). Frequency pattern test
consists of 60 patterns of three-tone burst in varying patterns of high- (1,122 Hz) and low- (880 Hz) frequency. Thirty items were
presented to each ear, with the listener humming or verbally labeling the patterns. Twenty subjects were between the age of 20-29
years and 10 subjects were between the ages of 60-70 years all with normal hearing sensitivities. For both the humming and labeling
conditions, mean scores of elderly subjects were significantly lower than those of young subjects. The average scores of young
subjects were 99.49% for the right and 99.67% for the left for humming. Scores for labeling were 93.99% for the right and 93.99%
for the left. Elderly subjects scores were 79.67% for the right and 80.66% for the left ear for humming. The scores for labeling were
47.33% for the right and 44.66% for the left. The results for the population in Korea identified a pattern that shows that the pattern
recognition abilities are degraded by aging. Performance for linguistic labeling is affected more by aging than humming. |
