Psychopaths not only lack feelings of remorse, empathy and guilt, but they also lack responsibility and fear of punishment, and have difficulty regulating their emotions.Psychopathic traits seem to present with similar symptomologies across thelifespan (i.e., childhood, adolescence, adulthood) ( Blair, 2005).
Results demonstrated that negative parental affects observed at ages 9–10 influenced the child’s later psychopathic personality at ages 14–15, based on both caregiver and youth self-reports. For these ‘parent-driven effects’, both genetic and non-shared environmental factors were important in the development of later psychopathic personality during adolescence. There were additional ‘child-driven effects’ such that children’s psychopathic personality at ages 9–10 influenced negative parent-to-child affect at ages 14–15, but only within caregiver reports.
Thus, children’s genetically influenced psychopathic personality seemed to evoke parental negativity at ages 14–15, highlighting the importance of investigating bidirectional effects in parent-child relationships to understand the development of these traits.
