2.10. Statistical Analysis

Levene’s test was used to assess the homogeneity of variance in each group. Then, two independent sample t-tests and one-way analysis of variance (ANOVA) were applied to determine the differences between the two groups (i.e., control vs. stress) and between the three groups (i.e., control vs. eustress vs. distress). Dunnett T3 was conducted as a post hoc test based on the studentized maximum modulus [49]. We also investigated the correlations between sAA and the behavioral results of accuracy or reaction time. Hence, we obtained Pearson correlation coefficients for these data.
