marginally significantp = 0.058
When comparing P3b amplitudes across time, the hypothesized interaction between Stimulus Type, Testing Session, and Group was marginally significant, F (1,22) = 4.01, p = 0.058, ω 2 = 0.007; there was also a significant interaction of Testing Session and Group F (1,22) = 14.58, p < 0.001,ω 2 = 0.025.
