The <Group for Research on Artificial Cognition> (GRACo) is an interdisciplinary group dedicated to the synthetic design of cognitive systems. The group is part of the Department of Exact Sciences at the State University of Feira de Santana (UEFS).

Main topics of research

  • Semiotic Processes
  • Meaning
  • Language
  • Comunication
  • Cognitive Adaptive Processes
  • Embodied and situated cognition

Focuses of research

  • fundamental constraints for the emergence of semiosis
  • differences between innate and learned sign systems
  • adaptive role of compositional languages
  • adaptive advantage of symbolic processes
  • hypothetic minimal neural substrate of these processes
  • mutual influences between different semiotic competences and low level cognitive tasks (attention, perceptual categorization, motor skill)
  • hierarchical presupposition of fundamental kinds of semiotic competences
  • symbol grounding processes


  • Theoretical Framework
    • Charles Sanders Peirce's Philosophy of Sign, Phenomenology and Pragmatism
    • Ecological Psychology
    • Embodied and situated cognitive science
    • Biosemiotics
  • Experimental Frameworks
    • Ethology and Neuroethology
    • Experimental Psychology
    • Synthetic Psychology
    • Complex Adaptive System (self-organization dynamics)
    • Biologically inspired computation
      • Evolutionary computation
      • ALife
      • Synthetic Ethology
      • Artificial immune systems
