Personal Experiences of Help and Harm Lead Georgetown Psychologist to Brain Study of Adolescents with Psychopathic Traits

Sunday, June 23rd, 2013

One of the most intriguing and controversial areas of ponerology is research involving children with psychopathic traits. The questions regarding nature vs. nurture are particularly numerous and potentially disturbing in these cases. And yet answering them might also offer the opportunity for developing more effective strategies to help these children, their families and those around them both while they are children and as they grow up.

Several researchers, such as Adrian Raine, have done work studying the brains and neurological responses of children who exhibit traits often found in psychopaths and today we look at another such researcher. (more…)

New Study Evokes Debate Over the Ethics of Using Biological Markers to Predict, Preempt Harmful Activity

Friday, March 29th, 2013

One of the “holy grails” of ponerology – and an achievement that will inevitably force us to confront extremely challenging ethical dilemmas – is an improved ability to predict harmful behavior before it happens.

Dr. Kent Kiehl of the Mind Research Network has been one of the more active researchers investigating what we can learn from brain imaging of psychopaths. And he and colleagues have recently published, in the Proceedings of the National Academy of Sciences of the United States of America, a study entitled “Neuroprediction of future rearrest.”

The study involved having 96 soon-to-be-released male prisoners perform computer tasks that required quick decision-making and inhibition of impulsive responses, while their brains were observed using functional magnetic resonance imaging (fMRI). The researchers focused in on the brain region known as the anterior cingulate cortex (ACC) and found that, when controlling for other known risk factors, those prisoners with less ACC activity than their fellow study participants were about twice as likely to be rearrested within 4 years of release as those with higher ACC activity.

We’ve already mentioned, in previous stories, that reduced cingulate cortex function is associated with psychopathy and has been identified in some violent criminal offenders.

The question is, as we zero in on markers like this – whether they be certain anatomical or functional characteristics of the brain, particular genetic features or anything else – what is the most ethical way in which to use this knowledge? (more…)
