"They are stimulus seekers and pose the greatest problem for parents as children" (Damasio, 2000). They are irresponsible, and have a lack or remorse for deviant behavior. "They have a chronic indifference to and violation of the rights of one's fellow human beings" (Alterman, Cacciola, McDermott, Mulholland, Newman, & Rutherford, 2000).
