Fig. 5.

CDA and contralateral α power suppression measured in experiment 2. Shown are the CDA results for matched distractor (top), one-distractor (middle), and eight-distractor (bottom) conditions. The waveforms are the difference waves for each set size, and the time windows for the stimulus event and CDA are highlighted accordingly. The bar graphs show mean CDA amplitudes during the highlighted window for each set size. Error bars on bar graphs represent SEs. The asterisks represent the results of planned t-tests (where *** is <0.001).
