Abstract


Introduction. The problem of research and evaluation of mental working and its mechanisms is considered one of the most important tasks of psychophysiology and applied sciences.

Purpose. The goal was to work out a method of testing and evaluate mental performance during the processing of information with different speed of presentation of stimuli with a closed cycle.

Methods. It is presented the method of research and estimation of mental working in the surveyed 19-20 years is presented, with the processing of multimodal information in the mode Go/Nogo/Go with a gradual increase and decrease of speed of presentation of stimuli with a closed cycle.

Results. It is established that the mental working capacity during processing of information on geometric figures is higher than verbal signals. It is proved the information reliability of the index of mental working capacity, the coefficient of efficiency of mental working capacity as well as the indicator of mobilization of functional reserves, which are calculated for geometric figures and verbal stimuli, provided that the information is processed with the gradual increase and decrease of the speed of presentation of signals. It is proved that during performing mental work on information processing in the reverse mode, the indicators of mental performance index, efficiency ratio, as well as the level of mobilization of functional reserves for verbal stimuli in boys were higher than that of geometric figures.

Originality. It is  proposed method of determining the mental performance and its index, the efficiency coefficient, as well as the level of mobilization of functional reserves during the processing of information of various modalities and complexity when using a reverse test.

Conclusions. The proposed method can be effectively used for assessing mental performance and using of functional brain reserves during the processing of information of various modalities and the speed of its presentation.

It is proved that the indicators of mental performance in our test with the reverse can testify in favor of their independent informative and with their help it is possible to evaluate different aspects of mental functioning and systemic mobilization of functional reserve of the brain.
