Someday, a military commander will look over a battlefield map to check the position of troops, tanks, artillery emplacements and the enemy, considering every contingency in the complex mission.

Koraly Pérez-Edgar's work over the years has demonstrated that extreme shyness observed in children is often a predictor of anxiety later in life.

Pérez-Edgar runs the University's Cognition, Affect, and Temperament Lab.
