 abstract={Counting belongs to the most basic and frequent mental activities of humans. The subject of this paper is the non-trivial case of counting, namely that with imprecisely specified objects of counting. We will show that both scalar and fuzzy cardinalities of fuzzy sets as well as their extensions to Atanassov’s intuitionistic fuzzy sets are not sophisticated, artificial constructions. On the contrary, they model and reflect human counting procedures under imprecision possibly combined with incompleteness of information.},
