Three temperamental influences on behavior. A: A reactive system for approaching rewards and a reactive system for avoiding threats or punishment compete for ascendance; in the absence of effortful control, the resultant of that competition is expressed in behavior. B: The engagement of an effortful control system permits the resultant arising from the competition of the reactive systems to be overridden, thus dampening the role of the reactive systems in determining behavior. Adapted from various statements by Rothbart, Eisenberg, and others.
