目的：本研究旨在探讨正常人群的特质冲动与抑制运动控制之间是否存在关联。方法：低冲动和高冲动的被试(由I7问卷评估，两组均为31人)执行停止任务。绩效差异通过独立样本t检验进行分析。结果：低冲动组和高冲动组在停止反应的速度(SSRT)上没有差异。然而，Meta分析显示，高冲动者比低冲动者在停止时稍微慢一些(效应大小=-0.26，p=0.06)。结论：只有少量证据表明普通人群的冲动性与较差的抑制性运动控制有关。
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.
