As described earlier, the Blame Externalization subscale is part of the Impulsive Antisociality factor of the PPI-R, which in turn would be expected to be related to tasks measuring response inhibition, since response inhibition is one part of the multifaceted impulsivity construct (Keilp et al., 2005; Reynolds et al., 2006; Sharma et al., 2013; Spinella, 2004). However, the relationship between this PPI-R factor and reduced inhibitory performance did not survive corrections for multiple comparisons in the current study. Furthermore, the PPI-R Carefree Nonplanfulness subscale, which also loads on the PPI-R Impulsive Antisociality factor, was not related to response inhibition in the current task. Carefree Nonplanfulness refers to an inability to plan ahead, which is indicative of impulsivity as also captured by the BIS-11 Nonplanning Impulsiveness factor (Patton et al., 1995) and the current results suggest that both tap aspects of impulsivity outside of those measured by response inhibition. These results are further consistent with the previously reported absence of a relationship between PPI-R Carefree Nonplanfulness and cognitive load in a working memory task (Sadeh & Verona, 2008)
