Influence of musical training on temporal productions when using fast and slow counting paces.

The aim of the study was to assess the ability to maintain a steady pace during a counting task, aloud or silently, when a fast (28 counts every 900 ms) or slow (18 counts every 1,400 ms) pace is adopted (target = 25,200 ms), and to test whether ability is the same for musician and nonmusicians. The study analyzes the mean and variability of 30 temporal productions. The results show more variability (a larger coefficient of variation: standard deviation/mean production) in the condition where the pace is slow, a finding consistent with previous reports with this task. This finding applies here in both the aloud and silent counting conditions and, most importantly, applies to both musicians and nonmusicians. The results also indicate that there is no significant difference for the absolute error (|mean production - target duration|). In brief, the capacity to keep variability low when maintaining a pace seems to gain benefit from musical training, and this training difference does not depend on counting aloud versus silently and is not restricted to brief intervals.
