Two studies investigated whether the sustained attention to response task (SART) is a better measure of impulsive responding than of sustained attention. Participants performed target detection tasks with global-local letter stimuli using one of two response formats: standard, responding to targets; and SART, withholding to targets. In the first experiment, performance in the SART changed rapidly over time, whereas performance in the standard format was stable over time. In the second experiment, performance in the SART was susceptible to global-local condensation tasks, a result previously found with highly impulsive individuals. Overall the results indicate that the SART is sensitive to impulsive responding.
两项研究调查了持续注意力反应任务（SART）是否比对持续注意力的测量更能有效衡量冲动反应。参与者使用两种反应形式之一，对全局-局部字母刺激执行目标检测任务：标准形式，对目标做出反应；以及SART形式，对目标不做反应。在第一个实验中，SART形式下的表现随时间迅速变化，而标准形式下的表现随时间保持稳定。在第二个实验中，SART形式下的表现易受全局-局部浓缩任务的影响，这是先前在高度冲动的个体中发现的结果。总体而言，结果表明SART对冲动反应敏感。
