Notes: Three effect sizes for each measure and each participant are presented. All effect sizes provide an estimate of change from baseline to treatment, in standard deviation units. The signs on the Choice Visual Detection and Rapid Automatic Naming effect sizes were inverted so that a positive sign uniformly indicates positive change across time. The first effect size, d, was calculated by subtracting the mean of the three baseline data points from the mean of the last three data points and dividing by the pooled standard deviation across all data points for an individual (Gillam et al., 2001). The second effect size, SMD_baseline, was calculated by subtracting the mean of the three baseline data points from the mean of all treatment data points and dividing by the standard deviation of the baseline data points (Busk & Serlin, 1992). The third effect size, SMD_pooled, was calculated by subtracting the mean of the three baseline data points from the mean of all treatment data points and dividing by the pooled standard deviation across all data points for an individual (Busk & Serlin, 1992).
