Abstract

A central problem of theories of grounded cognition concerns the grounding of abstract concepts in sensorimotor representations. The paper aims at providing a new basis for a theory of cogni-tive abstraction mechanisms. The focus will be on the notions of causal indexicals and affordances, understood as action related concepts that show different degrees of abstraction. Abstraction mechanisms will be characterized that allow the transformation of such obviously "grounded" concepts into more abstract ones. In this way, the relation between sensorimotor processes and abstract concepts will be described in detail, and general principles of abstraction will be determined.
