The study is aimed at analysing the position of intuitive thought as reflected in current polemics within the dual processes models. In the first section, theories concerned with functionality of heuristics are presented, where evolutionary and ecological lenses offer insights that uncover details of human cognitive functioning under uncertainty and time pressure. The shift from normative models towards alternative explanations of 'heuristic person' reasoning is discussed. In the second section, views of human cognitive uniqueness as manifested in inferential activity are presented, emphasizing the primacy of inferential cognitions in progression of human intelligence. Within cognitive linguistics and sociolinguistics, transmission and comprehension of relevant meanings is attributed to cognitive mechanisms that go beyond mere verbal functioning and underlie mutually efficient strategies in communication of humans as intelligent actors in various environments.
