ERP waves for the LPP. Mean ERP waves across 11 central-parietal electrodes relevant for the late positive potential (LPP) for neutral, negative, and spider pictures during the four tasks, separately for participants with spider fear (two top rows) and for participants without spider fear (two bottom rows). For each group, the first row shows the ERP waves between −100 and 800 ms, and the second row shows a blow up of the same ERP waves between +250 and +750 ms.
