  1. Hemisphere and lobe are additional predictors in the alpha model.
  2. LH = left-handers, RH = right-handers. Pre-D = pre-drive, post-D = post drive. For post hoc analyses < and > indicate the direction of the effect (e.g., 1st < 2nd refers lower levels of the outcome variable in the first half compared to second half of drive). Only relevant post hoc comparisons reaching statistical significance (p < .05) following corrections for multiple comparisons are reported for interactions.
