Statistical analyses were conducted via repeated-measure analysis of variance (ANOVA) or via Friedman ANOVA when the data did not meet the assumption of normality (tested with the Shapiro-Wilk test). When significant ANOVA effects emerged, we further explored the results with paired samples f-tests and the family-wise error ratę was controlled with the Holm-Bonferroni method (Holm, 1979). When data violated the assumption of normality, Wilcoxon signed-rank tests were used instead of paired f-tests. Effect sizes were computed by calculating the appropriate index out of the following: the partial eta sąuared index (r/j;) for standard ANOVA, or the Kendalls W (Sheskin, 2003) for Friedman ANOVA, or the r² in Wilcoxon signed-rank tests for pairwise comparisons. Statistical analyses were implemented in IBM SPSS Statistics version 22.
