Psychopaths react to human emotion differently to other people
The difference between otherwise similar people with anti-social personality disorder (APD) and psychopaths is the way the latter's brain reacts when confronted with human emotion, a new study has found.
Researchers at the University of Michigan, US, set out to uncover why both people with APD and psychopaths both act on impulse and display a disregard for others - but psychopaths also callously manipulate others.
Luke Hyde, an assistant psychology professor told Pacific Standard
magazine that because many studies had been done on criminals with very high levels of psychopathy, the team wanted to better understand adults with lower levels of anti-social and psychopathic traits.
The participants in the study were tested using a technique that experts hoped would distinctly measure the difference between people with APD and psychopaths, while confirming how the two groups also overlap in many ways.
To make their findings, published earlier this year in the Journal of Abnormal Psychology
, researchers recruited 103 adults from a database of psychologically profiled people managed by the University of Pittsburgh's Adult Health and Behaviour project.
