same side of the screen as the required response hand were considered low-conflict response (Lr). Trials in which the target letter appeared on the opposite side of the screen as the required response hand were considered high-conflict response (Hr) trials. Accordingly, for analysis, trials were segregated into four categories: LsLr, LsHr, HsLr, and HsHr. Pseudo-randomized presentation of stimuli generated 24 trials of each category type per block.
