Neural summed similarity effect for Experiments 2 & 3. Normalized oscillatory power shown as a function of binned summed similarity (defined in equation 1) for both targets (dashed lines) and lures (solid lines). Bins are defined as the lowest and highest 50% of the summed similarity distribution. Power is averaged over all frequencies in the 2–4 Hz delta band and in the channels within the frontal ROI (see Figure 4/5(b)) in the first half of the trial. Error bars reflect standard error of the mean.
