Scatterplots of relations between ΔNegLPP amplitude and self-reported past month severity of cannabis use-related problems (top row), # of CUD criteria in the past year (middle row), and lifetime # of serious cannabis quit attempts (bottom row). 400–1000ms, 1000–2000ms, and 2000–3000ms ΔNegLPP amplitude are presented from left to right. Pearson (MPS, CUD)/Spearman (Quit Attempts) correlation coefficients and associated significance values are presented in the bottom right of each scatterplot.
