Significant results with p < .05 are displayed in bold.
a
Effect sizes according to Cohen's d.
b
If not indicated specifically, group differences were computed using an independent samples t‐tests as parameters showed normal distribution in a Kolmogorov‐Smirnov tests. Level of significance was α = 0.05.
c
Due to non‐parametric distribution, group differences were tested using a Wilcoxon‐Mann‐Whitney test.
d
For the control of family‐wise error for DemTect subtests, Holm‐Bonferroni correction was applied.
