Abstract
Introduction Cognitive aging seems to be a process of global degradation. Performance in psychological tests of fluid intelligence, such as Raven's Advanced Progressive Matrices, tends to decrease with age [1]. These results are strongly contrasted by performance improvements in everyday situations [2]. We therefore hypothesize that the observed aging deficits are partly caused by the optimization of cognitive functions due to learning.

Networks with comparatively lower memory load achieve more stable activations of the new feature combinations than the "old" networks. This corresponds well to the results of the free-association mode in either network type where only the "young" networks are close to a self-organized critical state
