Cognition is a distinctive characteristic of the human brain, which distinguishes itself from all other mammalian species. It is therefore not surprising that when we speak of cognitive control, we naturally think of cognitive control in the brain [1]. Most importantly, cognitive control resides in the executive part of the brain, reciprocally coupled to its perceptual part via the working memory [2]. The net result of this threefold combination is the perception-action cycle that embodies the environment, thereby constituting a closed-loop feedback system of a global kind.
