Figure 3.

Results for the late positive potential (LPP) for the letter and picture tasks for neutral and negative figures (left), and for neutral and negative scenes (right) across 20 electrodes (average referenced). The top row shows mean ERP waves from 100 ms before to 1000 ms after stimulus onset. The bottom row shows mean amplitudes across 400–700 ms. The error bars show the 95% CI of the difference scores between negative and neutral pictures in each condition, and the brackets refer to the interaction between task and emotion. ***p < .001, *p < .05
