[Behavioral activity in an uncertain environment (the methodological characteristics of an experimental study)].

A fundamental resemblance between processes of probabilitive training and conditional reflex forming exist wile using lowintensive signal stimulus and probabilitive way of confirmation. A base of intrinsic unity of these methodical variants is a complicated way of elicitation of bond between signal stimulus and confirmation, absence of one-way interpreted information about an environment presuming probabilitive estimate using. In this case informative interaction between an individual and subjectively accidental environment takes place or the same, a process of subjectively probabilitive training. Accordingly probabilitive training is a dinamic process of training under conditions of subjective uncertainty based probabilitive estimate application and feedback elements existence.
