Threshold problem and differential psychophysics

The author has doubts as to well-known psycho-physical paradigm maintaining that for every individual principles of sensoric system operation are the same. To counterbalance it the author proposes new psychological branch taking into account individual peculiarities of an observer - differential psychophysics. Some experimentally found determinants of individual behaviour of observers are given, and possible solution of threshold problem is proposed in connection with one of them.
