Univariate multiple linear regressions indicated that the interaction predicted P200 to positive stimuli over the right hemisphere ( B = –0.54, Δ R 2 = 0.05, p = 0.05), and predicted P200 to each condition (including neutral) over the left hemisphere, though the positive condition was only marginally significant (positive: B = –0.50, Δ R 2 = 0.04, p = 0.06; neutral: B = –0.56, Δ R 2 = 0.05, p = 0.03; negative: B = –0.74, Δ R 2 = 0.07, p = 0.01).
