This abstract details a study of children by Texas A&M International University, Laredo, TX (C.F., C.S.), and the University of Texas, San Antonio, TX (R.H.), to determine the factors (including media) that may influence youth violence and aggression. Researches measured the degree of delinquency and agression as based on the Child Behavior Checklist (CBCL), as well as observable criminal behavior and bullying.
