[The invariance of subjective time scales].

Organization of subjective time scales was studied by various methods of duration scaling (reproduction, fractionation, multiplication, evaluation, measuring and cross-model selection). Computation of linear correlation coefficients between physical time and its subjective expression for various methods of scaling in different coordinate systems allows to make a conclusion about a degree form of psychophysical dependence. The value of function degree index varies in the range of 0.80-0.88 for verbal evaluation and 0.93-1.07 for other methods. The concept is suggested about the "active" and "passive" time.
