ABSTRACT: Here we analyze the well-studied case of vocal signs in vervet monkeys in order to (1) classify them according to the fundamental Peircean kinds of signs, (2) infer minimum brain organizational constraints for their interpretation, (3) hypothesize possible neuroanatomical substrates able to satisfy these constraints, and (4) propose an experiment based on the interpretation of signs in vervet monkeys to test these hypotheses.

ABSTRACT: Here we propose a new synthetic methodology (SNToolkit) to serve as a formal model to the well-studied case of semiosis in East African vervet monkeys (Cercopithecus aethiops) in order to: (i) propose a synthetic experiment to simulate the well-studied ethological case of intraspecific communication in vervets, (ii) infer the minimum organizational constraints for design a symbolic artificial mind, (iii) hypothesize possible neuroanatomical substrates able to satisfy these constraints. KEYWORDS: computational semiotics, computational neuroethology, animal communication, meaning process, semiotic synthesis.

TITLE: INTERACTIVE DIAGRAMS FOR CHARLES PEIRCE¹S CLASSIFICATIONS OF SIGNS: SOME IMPLICATIONS FOR THE EPISTEMOLOGY OF MATHEMATICS
Priscila Farias (PUC-SP) & João Queiroz (PUC-SP)
ABSTRACT: This article presents the first results of a research on new strategies for the visualization of sign classifications structures and processes. The focus of this research are the various (3-, 10-, 28- and 66-fold) classifications of signs described by Peirce. The main issue addressed here is how computer graphics and design methodology may help us to build dynamic and interactive models that serve as tools for the investigation of sign theory. Two models are presented. One of them concerns specifically the 10-fold classification, while the other deals with the deep structure of Peirce¹s various trichotomic classifications. The first is Œ10cubes, an interactive 3-D model of Peirce´s 10-fold classification. The second is Œ3N3, a computer program that builds equivalent diagrams for any n-trichotomic classification of signs, allowing us to analyze and compare different hypothesis regarding those classifications.
