The Sustained Attention to Response Task (SART) is a Go-No-Go signal detection task developed to measure lapses of attention. In this study, we examined the impact that warning signals, reliable and unreliable, have on SART performance. Eighteen participants performed a no-warning, reliable-warning, or unreliable-warning SART. Response times were faster, errors of commission lower, but errors of omission higher in the reliable-warning SART in comparison with the no-warning or unreliable-warning SART. There was a significant negative correlation between participants' errors of commission rate and their response times in the unreliable-warning and no-warning SART. This correlation was reduced in the reliable-warning SART. Making the task perceptually easier reduces the errors of commission, in contradiction to the mindlessness perspective, and reduces the speed-accuracy trade-off. These results, overall, support the view that the SART is primarily a measure of response strategy, not sustained attention per se.
持续注意反应任务（SART）是一种用于测量注意力不集中的 Go-No-Go 信号检测任务。在这项研究中，我们研究了可靠和不可靠的警告信号对 SART 表现的影响。18 名参与者进行了无警告、可靠警告或不可靠警告 SART。与无警告或不可靠警告 SART 相比，可靠警告 SART 中的反应时间更快，错误率更低，但错误率更高。在不可靠警告和无警告 SART 中，参与者的错误率与反应时间之间存在显著的负相关。在可靠警告 SART 中，这种相关性降低了。使任务在感知上更容易，减少了错误率，这与无意识观点相反，并且减少了速度准确性权衡。总的来说，这些结果支持这样一种观点，即 SART 主要是一种反应策略的衡量标准，而不是持续注意力本身。
