Researchers provide a neuro-hormonal explanation for emotional regulation problems in psychopathic patients.
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.
Neuroimaging study reveals structural and functional differences in brain areas associated with emotional regulation in those with personality traits linked to psychopathy or antisocial personality disorder.
Grandiose narcissists are more likely to be "mentally tough", experience less stress, and are less prone to depression.
According to a new study, boys who show behaviors consistent with psychopathic traits report they did not want to join in with laughter as much as their peers. Additionally, neuroimaging revealed reduced response to the sound of laughter in areas of the brain associated with emotional perception.
Researchers have developed new tests and math models to help quantify automatic moral and empathetic judgement.
According to a new study, those with psychopathic characteristics are less likely to react to a contagious yawn as their more empathetic peers.
Neuroimaging study reveals those with psychopathy have a 10% larger striatum than non-psychopaths. Researchers say the increased size of the striatum, a brain area associated with cognitive and social functions, may account for a higher likelihood of impulsive behaviors and increased need for stimulation often associated with psychopathy. Additionally, researchers suggest there may be an element of heredity in the neural anatomy, adding support to the neurodevelopmental perspective of psychopathy.
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.
Contrary to popular belief, those suffering from psychopathy are able to experience emotions, but they do have a blunted emotional response if their attention is directed toward something else. In essence, psychopaths feel emotions, but ignore them if they feel they might interfere with attaining personal goals.
Teens who display callous-unemotional traits are at higher risk of developing psychopathic traits as they enter adulthood.
While most people mellow with age, this does not appear to be the case for those with ASPD or psychopathy. Researchers report maladaptive behaviors associated with ASPD often get worse as people with the personality disorder age.
