Mindfulness Trait Predicts Neurophysiological Reactivity Associated with Negativity Bias: An ERP Study

Figure 3

Waveforms and 2D topographies of P2. Waveforms elicited by presentation of IAPS pictures (positive, negative, and neutral) at representative midline electrodes (Fz, FCz, and Cz) are shown in (a). 2D topographies of the mean amplitudes averaged between 140 and 280 ms scalp distributions showing the original activities elicited by positive, negative, and neutral pictures (b) and differences between activities elicited by positive and neutral, negative and neutral, and positive and negative pictures (c) are shown. Scatterplot representing age positively correlates with difference of the mean amplitudes of P2 averaged between 140 to 280 ms as elicited by positive and neutral pictures collapsed across five channels at the frontal location (F1, F2, F3, F4, and Fz) is shown in (d). Scatterplot representing CAMS-R positively correlates with difference of the mean amplitudes of P2 averaged between 140 and 280 ms as elicited by positive and negative pictures collapsed across five channels at the frontocentral location (FC1, FC2, FC3, FC4, and FCz) are shown in (e). (Pos: positive; Neg: negative; Neu: neutral; Pos-Neu: positive-negative; Neg-Neu: negative-neutral; Pos-Neg: positive-negative; CAMS-R: Cognitive and Affective Mindfulness Scale Revised; IAPS: International Affective Picture System).
