Group-mean performance (in z-scores) for YNH (open symbols) and ONH (filled symbols) participants on different cognitive tasks. Error bars represent ±1 SD. Gray panel frames indicate non-significant group differences (p > 0.05). Bold black panel frames denote significant results at p ≤ 0.05 that remained significant after applying a Holm-Bonferroni correction. The effect size is given by Cohen's d at the bottom of each panel.
