本研究旨在探讨持续注意力任务是否可以由无意识视角或有限资源视角来充分描述。176名参与者（88名女性和88名男性）被随机分配到两个信号显著性条件中的一个：高和低。收集了表现和自我报告状态，精力充沛的唤醒，紧张的唤醒，与任务相关的想法和与任务无关的想法。整体性能效率和警惕性衰减率受观察到的信号显著性水平的影响。任务后自我报告的任务无关思维与整体工作效率显著相关，但与警觉性下降无关。任务后的能量觉醒自我报告与整体表现和警觉性下降显著相关。研究结果支持资源理论关于警觉性下降的观点，与无意识理论关于警觉性下降的观点相矛盾。(C) 2008 Elsevier B.V.版权所有
The present study was designed to explore whether sustained attention tasks can tie adequately described by a mindlessness perspective or a limited resource perspective. One hundred and seventy six participants (88 women and 88 men) were assigned at random to one of two signal salience conditions: high and low. Performance and self-reported states, Energetic Arousal, Tense Arousal, Task-Related-Thoughts, and Task-Unrelated-Thoughts, were collected. Overall performance efficiency and the rate of the vigilance decrement were influenced by the salience level of the signal being observed. Post-task self-reports of Task-Unrelated-Thoughts were significantly related to overall performance efficiency, but not with the vigilance decrement. Post-task self-reports of Energetic Arousal were significantly related to both overall performance and the vigilance decrement. The results support a resource theory perspective in regards to the vigilance decrement and are in contradiction to the mindlessness theory in regards to the vigilance decrement.
