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.
