Despite such statisti- cal evidence for this trend, among US adolescents (ages 12–18 years), as well as “emerging adults” (ages 18–25 years) there are significant excep- tions to this pacification of violence. Both cohorts remain key outliers whose behaviors are particularly difficult to explain when considering their psychological development in this second decade of life, which fol- lows its own civilizing direction. Human development research suggests that an improved ability to understand others, regulate emotions such as anger and fear, skillfully relate to and cooperate with peers, and use language rather than intimidation to influence others promotes a sophis- ticated and gentle individual. As developmental psychologists search for clues to violence occurring later in life, they have long viewed the child- hood years as a time when the prevalence of aggression, seen commonly in squabbles among 2-year-olds over toys, gradually declines during elementary school years as a result of vastly improved cognitive abilities (Dodge, Coie, & Lynam, 2006; Loeber & Hay, 1993).
