Linear relationship between age and performance on the VMT for the dominant and non-dominant hands for each block. There was a significant linear relationship between age and performance with the dominant hand on days 1–5 (r = 0.744, p ≤ 0.05), days 6–10 (r = 0.627, p ≤ 0.05), days 11–15 (r = 0.790, p ≤ 0.05), and days 16–20 (r = 0.763, p ≤ 0.05) but not for days 21–25 (r = 0.235, p = 0.575). There was no significant linear relationship between age and the non-dominant hand on this task.
