Note. Alpha levels have been corrected using a Bonferroni correction within each outcome category (i.e., each column), such that alpha = .006 for rinse ratings, .017 for initial task difficulty ratings, and .008 for OSPAN ratings and performance. Italicized font indicates statistical significance relative to the corrected alpha level. ^†Indicates that equal variances between groups has not been assumed (based on a statistically significant Levene's test). “un” = Unsweet rinse condition. “s” = Sucrose rinse condition. “su” = Sucralose rinse condition. “hi” = High-effort condition and “lo” = Low-effort condition. Note that in some cases, data for each participant were not always available; see Additional file 3, for ns, means, and standard deviations.
