This work presents a theoretical revision regarding the theme of anger , its evaluation and intervention, directly related to aggression and important theories of the personality, focusing –primarily- in Eysenck’s theory. Two instruments were used on 200 children of both sexes, within the ages of 9 to 11 years old in three schools in Santafe de Bogota; one of these instruments was applied to measure anger (MAC scale of Anger) and another to measure the personality dimensions of Extroversion-Neuroticism.
