Results are corrected for multiple comparisons by applying a Bonferroni correction. Bold indicates two-tailed (p < 0.05) and one-tailed (p < 0.05/2) significant results. RT, Reaction time; R, Rewarded; NR, Not rewarded; H, High; L, Low. Partial eta squared (η²) values range from 0 to 1, and represents the proportion of total variance accounted for by the factor(s), while excluding other factors from the total explained variance (i.e., non-error variation) in the repeated measures ANOVA (83).
