- Аннотация: The subjective scale of elasticity was constructed in a purpose to make an active touch of objects with variable shape (without participation of other analyzers). Parameter of the psychophysical power function equals 2.45451±0.184485. It is shown, that such subjectively one-dimensional quality as elasticity is realized by the two-channel analyzer. The system of size estimations of subjective distinction in elasticity of pairs objects can be well described (r=0.98) with the help of a two-dimensional spherical (variability of radius is equal 12.97 %) spatial (Euclid) model. Two Euclid space axes of model correspond to neural channels, and the change of a corner of a turn (movement of a point on a circle) corresponds to the change of subjective quality of elasticity. The magnitudes of the elasticity which were calculated as a corner in the constructed two-dimensional model, coincide well with the direct estimations of magnitude of elasticity (r =0.97). Furthermore, from the direct magnitude of elasticity estimations, it is possible to calculate the distinctions between pairs of stimulus as an absolute magnitude of these estimations’ difference, which coincide well (r = 0.94) with the experimentally received distinction’s grades. The revealed mechanism, based on the resembling a neural element can be used for constructing a new informational cybernetic algorithm of variably shaped objects’ recognition.
