Abstract: In consideration of working memory as a means for goal-directed behavior in nonstationary environments, we argue that the dynamics of working memory should satisfy 3 Current correspondence: RIKEN, Frontier Research Program, Lab. For Information Representation, Hirosawa, 2-1, Wako-shi, Saitama, 351-01, Japan. email: nakahara@irl.riken.go.jp two opposing demands: long-term maintenance and quick transition. These two characteristics are contradictory within the linear domain. We propose the... (Update)
