The paper introduces an extension of the proposal according to which
conceptual representations in cognitive agents should be intended as heterogeneous
proxytypes. The main contribution of this paper is in that it details how
to reconcile, under a heterogeneous representational perspective, different theories
of typicality about conceptual representation and reasoning. In particular, it
provides a novel theoretical hypothesis - as well as a novel categorization algorithm
called DELTA - showing how to integrate the representational and reasoning
assumptions of the theory-theory of concepts with the those ascribed to the
prototype and exemplars-based theories
