Description

The aim of the present study was to comparatively investigate the effect of accent on word discrimination between young and older adults. The test stimuli were Japanese words spoken in two different accent conditions: standard accent and misplaced accent. The stimuli were presented to the subjects at the appropriate sound level (40dBSL) and low sound level (20dBSL) through a headphone.<br>The results revealed significant differences for each of the conditions of aging, presented sound level, and accent. In particular, the older adults showed lower percentages of correct answers in the low sound level condition and misplaced accent condition. Furthermore, the scores in the older adults were not correlated with the personal property characteristics, age, hearing ability or speech intelligibility. In contrast, in the young adults the percentage of correct answers was higher in the low sound level condition, and significantly declined in the misplaced accent condition.<br>It was thought that there was differential use of prosodic information in word discrimination between young and older adults. Thus, we should consider the age while examining prosodic information processing.
