Measuring the Duration of the Phase of the Formation of a Physiological Phenomenon as a Predictor of Conscious Sensation at the Visual-Motor Reaction "Go / No-Go" – Type in the Paradigm of Backward Masking

In a psychophysiological experiment, the effect of inhibition of the “Go/No-go” – type differential visual-motor reaction (DVMR) under the influence of a masker stimulus presented at different periods of its implementation was revealed; this effect is manifested in the range of stimulus onset asynchrony (SOA) from 40 to 100 ms. There is a relationship between the latent period of DVMR and the value of the SOA interval, described in a logarithmic scale by the equation of a straight line: the latency of the sensorimotor response is inversely proportional to the logarithm of SOA. The psychophysiological method based on measuring the degree of inhibition of the “Go/No-go” – type DVMR speed in the backward masking paradigm can be used to measure the duration of the formation of a physiological phenomenon as a predictor of conscious sensation. A possible mechanism of inhibition of the rate of realization of the “Go/No-go” – type "reaction during backward masking consists in a decrease in the intensity of the physiological phenomenon under the influence of the masker, which lengthens the latent period of the sensorimotor reaction.
