We modeled the effects of FTND,3 as a main effect and as an interaction term with valence, on baseline COR EMG. FTND was modeled as a continuous variable. Total FTND score interacted with valence in predicting COR EMG scores, F(3, 315) = 2.68, p < .05, with slopes indicating that those with higher FTND values had larger COR EMG responses to unpleasant slides than did those with lower FTND values, PE = 0.049, SE = 0.02, t(315) = 2.38, p < .02 (see Figure 1a).
