The assessment of the informational components of a functional state of locomotive crews members by means of the "Machinist" technique
It has been revealed that indicators of the informational components of a functional state of locomotive crews members received by means of the «Machinist» technique were sensitive to the workload increase. It has been revealed that the integral indicator of the «Machinist» technique, which included indicators characterizing visual attention capacity, its distribution and switching, perception resistance, ability to the differentiated assessment of the visual information, speed of decision-making, level of anticipative thinking, working memory level, spatial thinking and interference resistance, progressively decreased with the workload growth, caused by the excess of working hours over the established norms. It has been shown, that high sensitivity of the technique indicators to the workload is caused by similarity of the psychological maintenance of activity during the performance of the test task and real activity of the locomotive driver. In this connection, the consequences of the workload on the functions involved in the real activity affected the work of the functional system, that provided activity for the test task performance. The «Machinist» technique can be used for the dynamic control of a functional state and working capacity of locomotive crew members.
