IACAP 2011 presentation on cognition as management of meanings:
Cognition is proposed as a management of meanings for agents that have constraints to satisfy (stay alive, look for happiness, avoid obstacles, …).
(IACAP 2011 presentation http://cogprints.org/7584/)
The systemic approach to meaning generation for agents is used in an evolutionary perspective to cognition where robots are agents with derived constraints, meanings and intentionality.
