[The shaping of the behavioral act: the problem of intrasystemic heterochrony].

According to P.K. Anokhin's conception, the functional system of every behavioural act includes one and the same sequence of basic mechanisms, the main of them are afferent synthesis and making decision, realization of action, achievement of the result and evaluation of its parameters. The present work deals with the question about the extent of coordination in the development of these systemic mechanisms in the process of new behavioural act formation.
