在这项研究中，我们模拟了一个手动装配操作，参与者接触到两种不同的信息呈现方式，反映了两个任务条件（单调和更苛刻的任务条件）。我们研究了心理负荷（MWL）的变化如何调节事件相关电位（ERP）的P300成分，记录从无线脑电图（EEG），反应时间（RT）和任务无关的运动（从Kinect检索）的数量。我们发现，P300振幅的减少和增加的任务无关的运动的数量，都表明在单调的任务（较低的MWL）的注意力水平下降。在要求更高的任务中，施加稍高的MWL，这些趋势并不明显。RT没有显示出对应用的工作量水平的任何依赖性。这些结果表明，无线EEG，但也Kinect，可用于测量MWL的变化对工人的认知状态的影响。
In this study, we simulated a manual assembly operation, where participants were exposed to two distinct ways of information presentation, reflecting two task conditions (monotonous and more demanding task condition). We investigated how changes in mental workload (MWL) modulate the P300 component of event-related potentials (ERPs), recorded from wireless electroencephalography (EEG), reaction times (RTs) and quantity of task unrelated movements (retrieved from Kinect). We found a decrease in P300 amplitude and an increase in the quantity of the task unrelated movements, both indicating a decrease in attention level during a monotonous task (lower MWL). During the more demanding task, where a slightly higher MWL was imposed, these trends were not obvious. RTs did not show any dependency on the level of workload applied. These results suggest that a wireless EEG, but also Kinect, can be used to measure the influence of MWL variation on the cognitive state of the workers.
