Aggression levels in college students after exposure or non-exposure to an aggressive life experience
Through a secondary analysis of existing data, the authors researched the question of what types of aggressive behaviors are learned from an individual's social environment. The findings included data on three student groups: 1) students who had never been in military service; 2) students who had been in military service and had been to Viet Nam; and 3) students who had been in military service, but who had not been to Viet Nam. The results indicated that assault is clearly one aggressive behavior that appears to increase with exposure to an aggressive life experience.
