On adequate and constructive models of processing of meanings

Humans promote themselves in the universe, the totality of their realities, while by processing of meanings they enhance the effectiveness and efficiency of the promotion. Humans communicate by explanation and acquisition of meanings, while acquire meanings by their understanding and learning. In paper we provide language explanations of meanings on some realities tended to specifications of constructive and adequate models of meaning processing. We discuss constrains on meanings induced by the models and corresponding constrains on cognition of realities as well as provide experimental evidence supporting a viability of the models.
