Figure 4. Difference waves for old/new and repetition effects of distracters.
A. ERP old/new difference waves (studied minus new) for distracters at Pz.
B. Early ERP repetition effect (repeated minus initial presentations) for new distracters at Cz.
C. Early ERP repetition effect (repeated minus initial presentations) for studied distracters at Cz. Corresponding topographical maps are shown on the right. A star in each topographic map indicates the cortical location of the largest difference waves.
