A tantrum is an emotional outburst of ill humor or a fit of ba temper wherein the higher brain functions are unable to stop the emotional expression of the lower (emotional and physical) brain functions. It can be categorized by an irrational fit of crying, screaming, defiance, and a resistance to every attempt at pacification in which even physical control is lost. The person may not stand or sit on their own. Even when the "goal" of the person is met, he or she is not calmed.
