An alternative hypothesis for decline in temporal acuity during aging would be that the sound features are registered successfully: however, the ability to access the acoustical information required for the formation of a meaningful auditory object might be impaired.
The substantial improvement in temporal acuity following audiovisual training transferred fully to the visual task and did so regardless of variations in visual feature and stimulus location.
Second, individual differences in temporal acuity correlate across perception and action, 14, 15 similarly suggesting a common underlying mechanism.
Declines in auditory acuity [9] [10], temporal processing [11], memory [12], speed of information processing [13] [14] and the ability to filter out irrelevant competing auditory input [15] [16] also contribute to difficulties reported by older adults for hearing SIN.
Despite some improvement with practice, temporal acuity in this task does not fall below 20 30 ms in the best case, which is similar to the temporal resolution limit, and performance does not improve for comparison tasks with multiple stimulus presentations.
Consistent with results reported in young adults, the present data indicate that long-term musical experience shapes speech-in-noise perception [17] and auditory temporal acuity, as assessed by backward masking perception [26].
12 13 Moreover, the results of the HORIZON AMD, SECURE and SEVEN-UP studies demonstrate declines in visual acuity in subjects transitioned to PRN treatment from a fixed dosing scheme.
For example, temporal acuity is increased in the AL, whereby small time differences in the stimulus create longer time differences in the AL response (Szyszka et al., 2012; Stierle et al., 2013).
Specifically, musicians had enhanced speech-in-noise perception, auditory working memory and auditory temporal acuity (lower backward masking thresholds), compared to non-musicians.
The present study addresses this question by comparing directly the temporal resolution of human observers with their temporal acuity as measured in a temporal bisection task.
