OBJECTIVE: The present study investigates whether there is an association between trait impulsivity in the normal population and inhibitory motor control as assessed by the stop task. METHOD: Low- and high-impulsive participants (as assessed by the I7 questionnaire; both groups n = 31) performed the stop task. Differences in performance were analyzed by an independent samples t-test. Furthermore, a short meta-analysis was performed on this study and three previous studies with a similar aim. RESULTS: The low- and high-impulsive groups did not differ on the speed to stop the response (SSRT). However, the meta-analysis revealed that high-impulsives are marginally slower in stopping than low-impulsives (effect size = -0.26, p= 0.06). CONCLUSIONS: There is only minor evidence that impulsivity inthe common population is associated with poor inhibitory motor control.
