Interpretation of p-values: p < 0.05*, p < 0.01**, p < 0.001***; the significance level was adjusted by the sequentially rejective Bonferroni test to prevent the alpha error from accumulating (Holm, 1979); interpretation of BFs (Wagenmakers et al., 2018): BF < 0.33 (moderate evidence for the null hypothesis), BF < 0.10 (strong evidence for the null hypothesis), BF < 0.033 (very strong evidence for the null hypothesis), BF > 3 (moderate evidence for the alternative hypothesis), BF > 10 (strong evidence for the alternative hypothesis), BF > 30 (very strong evidence for the alternative hypothesis).
