What are the developmental patterns in the use of physical aggression between the ages of 2 years and 11 years? Is there a group of children who display atypically high levels of physical aggression throughout that age period? Is there a group of children who were not highly physically aggressive during toddlerhood who became physically aggressive when they entered school? Does the difference between the number of boys and the number of girls who are physically aggressive increase with age? What characteristics distinguish children who have a developmental pattern characterized by atypically high levels of physical aggression from those children who follow a typical pattern?
