Compromised emotional competence: seeds of violence sown early?

The authors expected less secure preschoolers to be less emotionally competent when interacting with peers at age 3 and that these emotionally incompetent children, especially those who showed much unregulated anger, would be less socially competent in kindergarten. These directional hypotheses were examined in a sample of 91 preschoolers, and all were corroborated.
