Toward scale-free like behavior under increasing cognitive load

Authors


Abstract

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.
