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 speed to stop the response (SSRT). However, the meta-analysis revealed that the high-impulsives are marginally slower in stopping than low-impulsives (effect size = -0.26, p = 0.06). The authors concluded that there is only minor evidence that impulsivity in the common population is associated with poor inhibitory control.
