Trumping by Blasts of Noise: , Self-Esteem, Shame, and Aggression in Young Adolescents

This experiment tested how self-views influence shame-induced aggression. One hundred and sixty-three young adolescents (M 5 12.2 years) completed measures of narcissism and self-esteem. They lost to an ostensible opponent on a competitive task. In the shame condition, they were told that their opponent was bad, and they saw their own name at the bottom of a ranking list. In the control condition, they were told nothing about their opponent and did not see a ranking list. Next, participants could blast their opponent with noise (aggression measure). As expected, narcissistic children were more aggressive than others, but only after they had been shamed. Low self-esteem did not lead to aggression. In fact, narcissism in combination with high self-esteem led to exceptionally high aggression.

Violent aggressive behavior in youth leaves scars on esteem would cause aggression. Even more problem- perpetrators, victims, and society at large.

Thus, early adolescence low self-esteem should be particularly aggressive may be a critical age period to initiate aggression when shamed because shameful events make them interventions targeted at changing self-views.
