The Sustained Attention to Response Task (SART) is a computer based Go-No-Go response task. Participants respond to frequently occurring neutral stimuli and withhold responses to rare target stimuli. Researchers have suggested the inhibition demands of the SART may mirror those which occur in some firearm accidents. Participants in the present experiment used a simulated nonlethal weapon to subdue threats (images of people holding guns) on large screens. Participants completed a target rich task (high Go low No-Go, like a SART), a target sparse task (low Go/high No-Go), a verbal recall task, and dual versions of the target rich and target sparse tasks with the verbal recall task as the secondary task. Results provided further evidence that some accidental shootings may result from failures of response inhibition and that additional cognitive load is detrimental to overall performance. Future studies should explore the role of response inhibition in realistic firearm scenarios.
持续注意反应任务（SART）是一种基于计算机的 Go-No-Go 反应任务。参与者对频繁出现的中性刺激做出反应，对罕见的目标刺激则抑制反应。研究人员认为，SART 的抑制需求可能反映了某些枪支事故中所发生的需求。本实验中的参与者使用模拟非致命武器来制服威胁（持枪人员的图像），这些威胁显示在大屏幕上。参与者完成了一项目标丰富的任务（高 Go 低 No-Go，类似于 SART）、一项目标稀疏的任务（低 Go/高 No-Go）、一项口头回忆任务，以及目标丰富和目标稀疏任务的双重版本，其中口头回忆任务是次要任务。结果进一步证明，一些意外枪击事件可能是由于反应抑制失败造成的，并且额外的认知负荷对整体表现不利。未来的研究应该探索反应抑制在现实枪支场景中的作用。
