Abstract:
Turn-taking as spontaneous role switching between chaser and evader is
studied. Agents are modeled as mobile vehicles with sensors and
internal recurrent neural networks. By using a genetic algorithm,
agents become able to take turns (follower) and at the same time to
allow the other to take turns (evader). Turn-taking allows a
variety of motion patterns, showing regular and irregular
spatio-temporal patterns. Turn-taking is a cooperative activity between
two agents, and preference for imperfect contingency is a sign of the
cocreative aspect of interaction. My contention is that cocreative
activity relies on cooperation. The adaptability of the turn-taking
system increases at the regular to chaotic turn-taking phase in
experiment.
