随着数字制造将传统的体力工作转变为更多的系统监控任务，需要新的方法来理解人们的精神工作量和长期集中注意力的能力。许多生理测量已经显示出检测认知状态变化的希望，最近传感器技术的进步提供了微创方法来监测我们的认知活动。例如，先前的功能性近红外光谱研究已经观察到在任务高需求期间脑血流动力学反应的变化。本研究探讨了持续注意任务中任务需求、疲劳和注意力退化的关系，以及它们对心率、呼吸频率、鼻温和前额叶皮层和颞中回血流动力学反应的影响。分析显示，相对于基线，疲劳对心率，呼吸频率和血流动力学反应的影响很小但很重要。相对于基线，任务需求对呼吸频率和鼻温有微小但显著的影响，但在心率和血流动力学反应方面没有观察到不同需求水平之间的差异。我们的研究结果让我们深入了解了生理数据可以告诉我们的认知状态、集中注意力的能力以及长期疲劳的影响。
As Digital Manufacturing transforms traditionally physical work into more system-monitoring tasks, new methods are required for understanding people's mental workload and prolonged capacity for focused attention. Many physiological measures have shown promise for detecting changes in cognitive state, and recent advances in sensor technology offer minimally-invasive ways to monitor our cognitive activity. Previous research in functional near-infrared spectroscopy, for example, has observed changes in cerebral hemodynamic response during periods of high demand within tasks. This work investigated the relationships among task demand, fatigue, and attention degradation in a sustained attention task, and their effect on heart rate, breathing rate, nose temperature and hemodynamic response in the prefrontal cortex and middle temporal gyrus. Analysis revealed a small but significant effect of fatigue on heart rate relative to baseline, breathing rate and hemodynamic response. Task demand had a small but significant effect on breathing rate and nose temperature, both relative to baseline, but no difference between levels of demand was observed in heart rate or hemodynamic response. Our results provide insight into what physiological data can tell us about cognitive state, ability to focus, and the impact of fatigue over time.
