- Notes: * = significant within-groups differences pre-post (pwithin ≤ 0.05) & significant interactions of the groups (pinteraction ≤ 0.05); ° = trends to significant within-groups differences pre-post (0.05 ≥ pwithin ≤ 0.10), calculated with ANOVA. Abbreviations: DTC dual task costs, η2: effect size η2 = .01; small effect, η2 = .06; moderate effect, η2 = .14; large effect.
