Age‐related changes in auditory temporal processing were investigated using a two‐tone flutter‐fusion paradigm. Ten elderly and ten young subjects (mean age 71.3 and 22.2 years, respectively) listened to pure‐tone pairs at six discrete interstimulus intervals (ISIs). The duration of the second tone (T2) was held constant at 100 ms. The duration of the first tone (T1) was variable. Subjects were instructed to adjust the duration of T1 at each ISI until they perceived flutter or fusion. In both groups, when critical T1 duration was plotted as a function of ISI, the curve was best described by a negative exponential equation. Elderly subjects demonstrated higher critical T1 durations and thus their curve was shifted to the right when compared to the young group. These results are similar to those found in flutter‐fusion experiments in vision. We hypothesize that decrements in temporal processing in elderly individuals may not be a modality specific phenomenon. Our results suggest a common underlying mechanis... |
