  Eigen mode selection ought to be a practical issue in some real game systems,
as it is a practical issue in the dynamics behaviour of a building, bridge, or
molecular, because of the mathematical similarity in theory. However, its
reality and accuracy have not been known in real games. We design a 5-strategy
game which, in the replicator dynamics theory, is predicted to exist two eigen
modes. Further, in behaviour game theory, the game is predicted that the mode
selection should depends on the game parameter. We conduct human subject game
experiments by controlling the parameter. The data confirm that, the
predictions on the mode existence as well as the mode selection are
significantly supported. This finding suggests that, like the equilibrium
selection concept in classical game theory, eigen mode selection is an issue in
game dynamics theory.
