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.
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.
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.
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.
Researchers investigate why people with psychopathic traits, and those who engage in acts of mass killing, tend to gravitate to certain careers.
It is estimated that 1% of the general population has psychopathic traits. Among the upper echelons of corporations, up to 3.5% of employees are psychopathic, with the percentage rising for those who are chief executives. Researchers investigate how those with psychopathic traits impact the workplace for other employees, and how corporate psychopaths end up costing the economy billions of dollars due to their unethical behaviors.
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.
Researchers reveal the neurobiology and typical behavior associated with psychopathic personalities. The paper explores the red flags that might mean you are in a relationship with a psychopath.
If there is a specific goal they want to accomplish, psychopaths are able to consider the thoughts of others, a new study reveals.
A new study using university students reveals those with high psychopathic traits showed a significantly reduces response time when being prompted to lie following training than those low levels of the traits. Researchers say their findings provide evidence that those with higher psychopathic traits may be better at learning to lie.
Taking a mobile neuroimaging system on the road to prisons, researchers look at the brain activity of those considered to be psychopaths and discover their brains are wired in a way that leads them to over-value immediate rewards while neglecting future consequences.
Researchers provide a neuro-hormonal explanation for emotional regulation problems in psychopathic patients.
