| Outline of Final Research Achievements |
This research investigated adaptive processes in human and animal cognition, aiming at i) elucidating general principles common to cognitive processes at various levels such as learning, culture, and evolution, and ii) building a computational model based on these principles.
i) Redundancy and diversity of information have been found to play important roles in adaptive processes concerning human learning and communication, the resilience of human societies, and cognitive strategies adopted by non-human species.
ii) A computational model using empirical data from a real field has shown that a strategy with large tolerance to unstable environment and great diversity can emerge from random decision -making, gaining ground for a general theory of cognitive adaptation.
