Towards adequate constructive models of mental systems

Mental systems represent realities, particularly, our utilities, have varying effectiveness with respect to our goals and are processed to support utilization and gaining the benefits from the utilities. Classifying mental systems are effective with respect to the goals insofar as they provide appropriate utilities regularly, i.e. are modeling the utilities constructively and adequately. In the paper we specify ontological, constructive and systemic models of mental systems comparable by expressiveness with algorithms and natural languages, provide arguments of their adequacy for explaining, understanding and human-computer interactions as well as convince to follow the ideas of inventors of algorithms in adequate modeling of mental behavior.
