Researchers have developed a new method for assessing psychopathy.
Those with dark personality traits such as psychopathy, sadism, low affective empathy, narcissism, cold-heartedness, and meanness, are more likely to sexually objectify those of the opposite sex.
Grandiose narcissists are more likely to be "mentally tough", experience less stress, and are less prone to depression.
Researchers investigate why people with psychopathic traits, and those who engage in acts of mass killing, tend to gravitate to certain careers.
Researchers have developed new tests and math models to help quantify automatic moral and empathetic judgement.
Activities targeting agreeableness were shown to reduce Dark Triad personality traits. However, those with Dark Triad personality disorders are less likely to want intervention to increase agreeableness.
Neuroimaging reveals 'successful' psychopaths (those who can control their antisocial tendencies) have greater levels of gray matter density between the left and right ventromedial prefrontal cortex. This area of the brain is implicated in self-regulatory processes, including reactive emotions.
While conventional thought considers those with psychopathic traits to be outgoing, charming, and bold, researchers say that many with psychopathy are more introverted.
Researchers investigate why some people take pleasure in hurting more vulnerable people.
