From: Aging and distractor resistance in working memory: Does emotional valence matter?
Grand-average ERP waveforms across three conditions of emotional distractors in the n-back task in older and young adults. The P2 amplitude was calculated as the average amplitude at Cz, FC1, FC2, FCz, and Fz; the N2 amplitude was calculated as the average amplitude at Fz, Cz and FCz; the LPP amplitude was calculated as the average amplitude at Cz, Pz, CP1 and CP2. Dotted rectangles represent the time windows used for the analysis of each ERP component
