Note. Bold η_p² represents significant effect sizes, ↑ result significantly (p < 0.01) higher in SZ group (n = 35, HC n = 35), ↓ result significantly (p < 0.01) lower in SZ group, -n.s. Correlations significance *p < 0.01, **p < 0.001

Bold font indicates statistically significant effects, including Bonferroni correction for multiple testing
