A study published in Archives of General Psychiatry reveals that psychopathy is characterized by reduced grey matter volumes in key brain areas, leading to impaired empathy and moral behavior. The findings suggest a clear behavioral difference between psychopaths and non-psychopathic offenders with anti-social personality disorder.
Scientific research challenges common myths about psychopathy, revealing it's not just a matter of genes or inalterable. Studies show that psychopathic individuals can exhibit anxiety and dysphoria, and intensive treatment can reduce violent behavior.
A study by Cornell University researchers found that psychopathic killers use specific word patterns when describing their crimes, including more conjunctions and words related to physical needs. These patterns can help identify potential psychopaths, potentially aiding in diagnosis and treatment.
A study by Daniel Bartels and David Pizarro found a strong link between utilitarian responses to moral dilemmas and psychopathic, Machiavellian personality traits. Individuals with these traits are more likely to prioritize overall consequences over personal feelings and values.
A new project led by University of Chicago researcher Jean Decety will use fMRI technology to examine the neural circuitry of criminal psychopaths in prisons. The research aims to identify the brain networks necessary for empathy and develop targeted therapies.
Children with psychopathic tendencies don't respond quickly to fearful faces, suggesting a deeper issue with processing threats. This suggests that addressing callous unemotionality may be more effective than teaching attention to fearful faces.
A study published in The Canadian Journal of Psychiatry identifies four subtypes of pathological gamblers, each with unique characteristics and levels of psychopathology. The findings suggest that different treatments may be needed for each group, highlighting the complexity of this disorder.
Researchers found that children with a specific serotonin transporter gene variant are more likely to exhibit psychopathic traits if they grow up poor. These traits include lack of empathy, arrogance, and deceitfulness. The study suggests that socioeconomic environment influences the expression of this genetic trait.
A new study suggests that an underlying cause of psychopathic behavior may be frontal lobe dysfunction, with participants showing striking similarities to those with brain damage. The research examined the emotional and cognitive aspects of Theory of Mind abilities in criminal offenders and patients with frontal lobe damage.
Researchers found that individuals with high impulsive/antisocial traits had a hypersensitive dopamine response system, which may contribute to psychopathic behavior. The study suggests that this heightened response could make individuals less fearful of consequences and more prone to aggressive behaviors.
Researchers found that psychopaths have a hyper-reactive dopamine reward system, linked to violent crime, recidivism, and substance abuse. The study suggests that impulsive traits and heightened attraction to rewards overwhelm concerns about risk, contributing to problematic behaviors.
Researchers at Binghamton University found that when water striders have the freedom to move between groups, females prefer to cluster around non-aggressive males. This suggests that a 'gentleman' approach to mating is beneficial for group productivity. In contrast, male psychopaths disrupt the group's dynamics and reduce fertility.
Researchers at King's College London discovered a significant reduction in the integrity of a key brain tract associated with emotions and decision-making in individuals with psychopathy. The findings suggest that biological differences in the brain may underpin psychopathic behavior.
Researchers studied child/adolescent psychopathy, finding it resembles adult version but with areas of instability that could inform interventions. The special issue examines various aspects, including genetics, temperament, and parenting styles.
Researcher Joseph Newman challenges the loaded label of 'psychopath,' arguing it's applied too liberally without understanding key elements. His work suggests psychopathy is a learning disability that makes individuals oblivious to consequences, with significant implications for treatment and behavioral interventions.
Research author Dr. Tarja Ketola suggests that companies using psychopathic practices can overcome mental burdens by integrating personal and professional values. By applying virtue ethical values, 'psychopathic' companies can move towards ideal responsibility and genuine corporate responsibility.
New research reveals distinct brain structure and function differences in adolescents compared to adults, leading to impulsive decision-making and increased risk-taking behavior. Puberty appears to be a critical stage of development, characterized by heightened novelty seeking and exploratory behavior.
The study found that psychopaths have abnormal wiring in the hippocampus and corpus callosum, leading to impulsiveness, lack of emotions, and social disconnectedness. This suggests a neuro-developmental root for psychopathy, with faulty brain development causing structural abnormalities.
