The local limb cooling provides the special psychophysiology reaction as alteration of tremor parameters. Shannon’s entropy after limb cooling is researched. The efficacy of such approaches for quantity estimation according to Eskov-Zinchenko effect at biomechanics is presented. Entropy E value and quasi-attractor parameters for one person with multi repetition of tremor registration (N=225 repetition) is shown. All these 15 samples with 15 series (registration of tremorogramm of one person) present the stable value of E and quasi-attractor sequence for 225 repetitions. When the Lorenz attractors demonstrate mixing property the invariant means correspond the determined chaos. But the stress perturbation (5 min. cooling of limb in water t = 5 ºС) does not change the E value. Three groups of subjects do not present the distinction between groups without stress and after cooling of limb. So it is necessary to construct the new theory for cooling stress (not stochastic approach) in psychophysiology. The new approaches is realized according to the new theory of self-organization chaos. As a result, E entropy parameters are not obtained while the quasi-attractor (S) parameter for termograms differ significantly. This proves the uniqueness of self-organization chaos theory, and opens up new opportunities to use this new theory in psychology and psychophysiology. Objective evaluation of stress – the human response to external agents – is a very difficult task for the quantitative description and simulation. As part of chaos theory self-organizing it now becomes possible. In this case, Eskov-Zinchenko effect will be recorded only regarding quasi-attractors and matrix of pairwise comparison of samples with the calculation of k matches.

The reaction of the regulatory systems of the neuromuscular system of the human to the various acoustic effects (white noise, rhythmic music, classical music, hard rock) using special methods (e.g. chaos theory, self-organization) and methods of conventional statistics was studied. The state of hearing with or without acoustic impact is studied. However, the approach used is based on the analysis of the quasi-attractors parameters of the neuromuscular system (postural tremor) with simultaneous registration of left and right hand tremorogramm (in terms of sound effects). Acoustic effects played a role of a disturbing factor for tremor regulation (and muscle activity); it changes the psychophysiological state of the subject (N.A. Bernstein C and D regulation system). The designed matrix method of analysis enables the identification of systems with chaotic organization that was shown in this work by comparing left and right hand tremorogramm of subjects at different acoustic effects. The acoustic effects are regarded as disturbing influences affecting the mental state of homeostasis. In this case the main task is a quantitative assessment of mental status test calculations by tremorogramm parameters. Quasi-attractor parameters calculation method demonstrates the differences in tremorogramm of left and right hands and tremor responses to acoustic feedback. This employs a new approach in the evaluation of motor asymmetry and the method of recording the parameters of mental homeostasis by tremorogramm of chaotic dynamics. The problem of registering human mental status in cognitive psychology is resolved with a high degree of uncertainty (Bernstein).

The acoustic effects are considered as disturbance affecting the mental state of homeostasis. In this case the main task is to hold a quantitative assessment of the mental state by means of calculating tremorogramm parameters. A method for calculating quasi-attractor parameters, which shows differences in left and right hand tremorogramms and tremor responses to acoustic feedback. In fact, a new approach in evaluating motor asymmetry and the method of recording the parameters of mental homeostasis by chaotic dynamics tremorogramm are proposed.
