On the short-term memory span

The propositions of vector quality of short-term memory span and the expone ntial dependence of this volume on the extension of events' alphabet indice s are considered. Its incompetence is shown. The theoretical basis of the p ossibility to prognoze the short-term memory span on multiplicative alphabe ts of different order in order of the theory of probabilities in discussed. The method of experimental examination of this possibility is suggested.
