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

Figure 4

Waveforms and 2D topographies of LPP. Waveforms elicited by presentation of IAPS pictures (positive, negative, and neutral) at representative midline electrodes (CPz and Pz) are shown in (a). 2D topographies of the mean amplitudes averaged between 400 and 700 ms scalp distributions showing the original activities elicited by positive, negative, and neutral (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 LPP averaged between 400 and 700 ms as elicited by negative and neutral pictures collapsed across five channels at the frontocentral location (FC1, FC2, FC3, FC4, and Fz) are shown in (d). (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).
