In 2016, it will be 120 years since the birth of N.A. Bernstein. His critical article was addressed to the conditioned-reflex theory of I.P. Pavlov and was published almost 60 years ago, but to the present time Bernstein hypotheses of "repetition without repetition" has not been studied. Quantitative description of these experimental results is now performed on the basis of construction of samples pairwise comparisons matrices under conditions of multiple repetitions of movements. The quantitative results show differences between voluntary (tapping) and involuntary (postural tremor) movements. It is proved that from the standpoint of chaotic assessment there aren't significant differences between these movements. New methods were presented for calculating the psychophysiological parameters of man. The new concept of Eskov-Zinchenko effect was presented, which demonstrates the chaotic kaleidoscope of statistical distribution functions f ( x ) of the obtained samples, the spectral densities of signals and their autocorrelation A ( t ). The role of consciousness is being discussed in organizing various types of movement. It is proved that the alleged involuntary movements (tremor) and voluntary movements (tapping) differ insignificantly from each other. From the standpoint of the stochastics, these two types of motion are chaotic in fact, because statistical distribution function f ( x ) changes randomly. The new theory of chaos-self-organization suggests methods of calculation of matrices of pairwise comparisons of samples that provide a clear distinction between tremor and tapping, i.e. between involuntary and voluntary movements. Voluntariness itself, i.e. increasing the role of consciousness in movements, is performed by increase in percentage of stochastics if we compare consecutive samples of tremorogramms and tappingramms. It represents quantitatively the Eskov-Zinchenko effect in evaluation not only the movement, but also in implementation of regulation of various functional systems that provide homeostasis.
