Table 1.

Two-way MANOVA results for the reference, absolute and relative θ power. The respective θ power measure at MESOIs is the dependent variables, with group (NACs vs. LTAAs) as the between-subjects independent variable and stimulus (target vs. rare non-target vs. standard non-target) as the repeated-measures independent variable. Post-hoc two-way ANOVA results for each of the dependent variables taken on their own is shown below the overall MANOVA result.
