In a study that addressed the relationship between trait impulsivity and inhibitory control (two features known to be impaired in a number of psychiatric condition, including alcoholism), Aichert et al. (2012) found significant associations of BIS-11 impulsivity with commission errors on a Go/NoGo task and directional error on an anti-saccade task, but not on stop signal and Stroop tasks. Latent variable analysis revealed that 12% of variance of the “prepotent response inhibition” construct could be explained by the BIS-11 impulsivity. However, the magnitude of the associations was small, indicating that while a portion of variance in prepotent response inhibition can be explained by psychometric trait impulsivity, the majority of variance remains unexplained. Thus, these findings suggest that prepotent response inhibition paradigms can account for psychometric trait impulsivity only to a limited extent. In another study, Lijffijt et al. (2004) investigated the association between trait impulsivity in the normal population and inhibitory motor control, as assessed by both the stop task and by a short meta-analysis of three studies. They did not find any difference between high-impulsives and low-impulsives on the
