Toward scale-free like behavior under increasing cognitive load



To understand how cognition and response selection processes might emerge from dynamic brain systems, we analyzed reaction times during the performance of both a working memory task and a choice reaction time task at different levels of “cognitive load.” Our findings suggest a continuous transition—tuned by load—from random behavior toward scale-free like behavior as an expanding connectivity process in a network poised near a critical point. © 2012 Wiley Periodicals, Inc.
