Behavior recognition process and behavior generation process have a close relationship in humans' brains. It is expected that humans' brains understand the meaning of behavior and create symbols through co-development of recognition and generation processes. In this paper, we propose a novel method for the integration of behavior patterns and symbols using associative memory in order to realize the co-development processing. In the model, behavior recognition process and generation process are practiced based on a mutual dynamics. We also confirmed the feasibility of the method on humanoid simulator.
