At the edge of graspability: Substances and aggregates

This paper explores the relation between the cognitive and perceptual aspects of substances and aggregates and the kind of grasp they require. It focuses on how the reference to the effector of the grasp (the entity that comes in contact with the object) is realised in a corpus of linguistic descriptions of the grasp of substances and aggregates. In particular, this work investigates whether the position of such entities on a scale of individuation influences the way in which the effector of a possible grasp is referred to in an action description task.
