Executive functions
Executive functions (also known as cognitive control and supervisory attentional system) is an umbrella term for the management (regulation, control) of cognitive processes, including working memory, reasoning, task flexibility, and problem solving as well as planning and execution.The executive system is a theorized cognitive system in psychology that controls and manages other cognitive processes, such as executive functions. The prefrontal areas of the frontal lobe are necessary but not solely sufficient for carrying out these functions.
