The activations in the γ and α ranges were entered into mixed-model ANOVAs with category knowledge (familiar versus unfamiliar) and experiment (Experiment 1 versus Experiment 2) as between-subject factors, phase (presentation versus occlusion) and hemisphere (left versus right) as within-subject factors. The ANOVA in the γ range (25–45 Hz) revealed two effects that approached significance: an interaction between experiment, category and phase, F 1,44 = 2.818, p = 0.100, η p 2 = 0.06 , and a main effect of category knowledge, F 1,44 = 2.772, p = 0.106, η p 2 = 0.06 .
