Researchers from several universities recently collaborated on a study to determine how genetic, environmental, and interpersonal factors influence the development of psychopathy. Psychopathy is characterized by lack of emotion<\/a>, dysfunctional attachments<\/a>, lack of remorse or guilt, and often antisocial tendencies, thought to be caused by genetic factors. The researchers sought to determine how environmental factors, such as peer influence, parenting, neglect, or abuse, affected two specific traits of psychopathy\u00e2\u20ac\u201dfearless dominance (FD) and impulsive antisociality (IA).<\/p>\n

Using the Psychopathy Checklist-Revised (PCL-R) and the Multidimensional Personality Questionnaire (MPQ), the researchers assessed 2,604 twins, all 17 years old, for several factors. They evaluated the parent-child relationship<\/a> and social environment, including peer interactions. They assessed levels of antisociality and prosocial behaviors and also gauged academic performance in school. Additionally, the team looked at external events including legal issues, school problems, and other stressful life experiences<\/a>.<\/p>\n

They found that the male twins exhibited more psychopathic behaviors overall. \u00e2\u20ac\u0153There was a moderate to large gender difference on MPQ-FD and MPQ-IA, with boys scoring higher on both,\u00e2\u20ac\u009d said the researchers. \u00e2\u20ac\u0153Boys also scored higher on antisocial peers, mother-child relationship problems, and school and legal problems. Girls scored higher on academic achievement and engagement and family level problems.\u00e2\u20ac\u009d They believe these findings regarding relationship problems are significant. \u00e2\u20ac\u0153This pattern of disrupted parent-child relationships and antisocial tendencies then initiates a sequence of developmental processes leading to academic failure, peer rejection, deviant peer af\u00ef\u00ac\u0081liation, drug use<\/a>, and delinquency.\u00e2\u20ac\u009d They added, \u00e2\u20ac\u0153Less discussed are factors that underlie the initial disrupted parent-child relationship, such as a child\u00e2\u20ac\u2122s undercontrolled temperament or the parent\u00e2\u20ac\u2122s own antisocial traits that then in\u00ef\u00ac\u201auence his or her parenting practices. We propose that genetic factors are a likely source of such individual differences that then in\u00ef\u00ac\u201auence other putatively environmental variables such as parent-child relationship problems.\u00e2\u20ac\u009d<\/p>\n
