Task-specific and variability-driven activation of cognitive control processes during motor performance.

Although the ability of the full model to predict manual dexterity performance did not quite achieve the threshold for statistical significance ( R 2 = 0.26, F (7, 39) = 1.98, p = 0.08), set shifting abilities (WCST PE ; β = −0.419, t (46) = −2.72, p = 0.01), response planning (TOL time/acc ; β = −0.370, t (46) = −2.32, p = 0.03), and working memory capacity (CBT mspan ; β = −0.366, t (46) = −2.10, p = 0.04) appear to explain unique portions of the variance in manual dexterity.
