Results for the late positive potential (LPP) to picture onset.

<p>(A) Grand average waveforms of the LPP-relevant electrodes for the three picture categories across participants. Note that the arousal effect on the LPP is apparent as the relative positivity between 400 and 800 ms after picture onset for arousing (i.e., pleasant and unpleasant) pictures versus neutral pictures. (B) Magnified version of (A) for individuals with high and low self-reported trait mindfulness separately. (C) Graphs depicting the mean amplitudes of the LPP-relevant electrodes between 400 and 800 ms after picture onset for the three picture categories for all participants (left, <i>N</i> = 51) and for high (<i>n</i> = 25) and low (<i>n</i> = 26) self-reported trait mindfulness separately (right). (D) Topographical distribution of the mean amplitude differences between 400 and 800 ms after picture onset between the arousing (i.e., combined pleasant and unpleasant) pictures versus neutral pictures, with electrodes selected for analysis in magenta (A1 (Cz), A2, A3 (CPz), A4, A19 (Pz), D1, D15, D16, C1, B1, and B2). The 95% <i>CI</i> refers to each individual condition mean. FFMQ-NR = Nonreactivity subscale of the FFMQ.
