At the time and location of the N300 (early, parietal), theta power was also greater during prospective memory than ongoing task trials (prospective memory: 3.87 μV 2 , ongoing task: 2.79 μV 2 ; 95% CI [−1.61, −0.62]; t (15) = −4.85, p = 0.001; Cohen's d = −1.25) (Figure 8B ), and alpha power showed a trend toward being greater during prospective memory (prospective memory: 2.54 μV 2 , ongoing task: 2.06 μV 2 ; p = 0.088) (Figure 8B ).
