Subjective uncertainty, purposeful behavior, and theory of functional systems.
Neglect of probability prognosis orients the theory of functional systems to description of rigidly determined forms of behavior (congenital behavior, frontal syndrome, etc.). The authors suggest an original concept for analysis of behavior under conditions of subjective uncertainty based on probability estimations. It contains all classical components of a behavioral act model developed by P. K. Anokhin. The role of probability prognosis at the stages of making decision (purpose) and formation and realization of the program of actions is argued. Two new components are added to the classical model: memory buffer and system of making probabilistic decision for modifying the program of actions. Such an approach essentially extends the potentialities of using the theory of functional systems, making it usable not only for rigidly determined behavior but for behavior under conditions of subjective uncertainty.
