Differences in discrimination performance between treatments approached significance (Friedman’s test: n = 5(8), χ 2 = 14.73, p = 0.065) but subsequent post-hoc analyses (pair-wise Wilcoxon Signed-Rank tests followed by the Bonferroni correction for multiple testing) revealed that discrimination performance in all tasks was statistically indistinguishable (all pairwise comparisons: adjusted p = 1).
