Figure 1.

Results for the early posterior negativity (EPN) for the letter and picture tasks for neutral and negative figures (left), and for neutral and negative scenes (right) across 12 electrodes (average referenced). The top row shows mean ERP waves from 100 ms before to 400 ms after stimulus onset. The bottom row shows mean amplitudes across 200–280 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
