[The relationship between astronauts erroneous actions, their psychophysiological state and work and rest regimen]

The correlation analysis of the data obtained in the MIR 18, and 21 through to 23 main missions was supportive of the strong dependence of erroneous actions by cosmonauts, their psychophysiologic state and the work/rest schedule. This conclusion guidelined the development of a prototype of technique to perform an integrated analysis of erroneous crew actions which can also help to identification of impacts of psychophysiologic state and deviations from the requisite rest/work schedule in order to set the origin of erroneous actions, and to work out recommendations towards the enhancement of ground-based crew training and other matters. With these findings, the predictive virtues of the technique has been demonstrated.
