Processing time in the elderly: the effect of the ability to temporal resolution in jobs of ordering a series of sounds

PURPOSE: to determine the effect on the ability of temporal resolution in the temporal ordering of a series of sounds with time of stimulation and varied interval inter-stimulus in an elderly population with or without hearing loss. METHOD: 10 (ten) elderly individuals with hearing loss from mild to moderate, who did or did not use hearing aids and 5 (five) subjects without hearing loss, aged from 60 to 80 years old, were tested for temporal ordering of series of sounds with pure tone, named standard pattern of Duraction, and musical tone, named standard test for melodic duration and temporal resolution Gaps-in-Noise test or GIN test. RESULTS: in the analysis of the test of temporal resolution as the percentage of correct identification, it was found that the group with no hearing loss has a higher percentage of identification of gaps than the group with hearing loss. Thus, individuals with hearing loss had worse threshold detection gaps (average of 1.4 milliseconds) than individuals without hearing loss (4.6 milliseconds). In the analysis of each test of ordering series of sounds, there were no statistically significant differences between groups. There was no significant correlation between the performance of the elderly with and without hearing loss among the temporal processing tests. CONCLUSION: the ability of temporal resolution does not affect the ability of temporal ordering of a series of sounds with duration of stimulation and varied inter-stimulus intervals in the elderly with or without hearing loss.
