“…The latter limitations are problematic as they affect estimates of performance variance, which themselves affect experimental effect calculations (Borenstein, Hedges, Higgins, & Rothstein, 2009; Dunlap, Cortina, Vaslow, & Burke, 1996). For instance, in repeated measures designs, even if the task order is randomized or counterbalanced to minimize carryover effects (Park, Bose, Notz, & Dean, 2011), the total time on task is increased when compared with nonrepeated measures designs. This might have different implications for task performance in the involved experimental groups.…”
