Liars' Brains Wired Differently
This finding is interesting...
A USC study of pathological liars shows first evidence of structural differences in the area of the brain that enables most people to feel remorse.A University of Southern California study has found the first proof of structural brain abnormalities in people who habitually lie, cheat and manipulate others.
While previous research has shown that there is heightened activity in the prefrontal cortex, the area of the brain that enables most people to feel remorse or learn moral behavior when normal people lie, this is the first study to provide evidence of structural differences in that area among pathological liars.The research led by Yaling Yang and Adrian Raine, both of the USC College of Letters, Arts and Sciences is published in the October issue of the British Journal of Psychiatry.The subjects were taken from a sample of 108 volunteers pulled from Los Angeles' temporary employment pool. A series of psychological tests and interviews placed 12 in the category of people who had a history of repeated lying (11 men, one woman); 16 who exhibited signs of antisocial personality disorder but not pathological lying (15 men, one woman); and 21 who were normal controls (15 men, six women).
