Table 2.

One-way MANOVA and MANCOVA results for the reference (target stimulus) and relative θ power. The respective θ power measure at MESOIs is the dependent variables and group (NACs vs. LTAAs) is the between-subjects independent variable. The covariates are either the P3b amplitude at Pz taken on its own or the P3b together with the reference θ power measures at each of the MESOIs. Post-hoc one-way ANOVA (ANCOVA) results for each of the dependent variables taken on their own is shown below the overall MANOVA (MANCOVA) result.
