The Graphic-Linguistic Distinction Exploring Alternatives

What properties, if any, distinguish graphical representations fromlinguistic representations? This paper looks for answers in the literatureof philosophy, logic, artificial intelligence, and cognitive psychology, andextracts seven alternative binary classifications of representations thatmay characterize the graphic-linguistic boundary. We assess eachalternative by two standards: (a) whether it extensionally fits the graphic-linguistic distinction, and (b) how far it explains the properties commonly attributed to graphic representations but not to linguistic ones.
