A psychopathy is defined as a person who suffers from a chronic
mental disorder and exhibits abnormal and violent behavior in social
situations. According to Fallon, psychopathy is not considered a disease
because it is currently too difficult to specifically define. There are no
obvious, crucial, or physical characteristics about a person that lead others
to distinguish them as a psychopath. As a result, psychopathy is categorized by
DSM as a disorder or a syndrome.
Brain scans are
able to identify psychopaths as they show depleted tissue regions within the
brain that are characteristic of psychopathy. An experiment conducted by the
University of Montreal attempted to analysis the difference between
psychopathic offenders, violent offenders, and non-offenders. The experiment
examined the brain activity in each group while preforming a series of tasks.
The violent or non-psychopathic offenders and non-offenders showed similar
brain functioning when they completed the tasks during the experiment. The
psychopath participants had a different response.
Psychopaths exhibit no response to threats, are extremely
emotionless and their behavior is often deliberate upon beforehand. Fallon
contemplates his previous experiences when he is identified as a psychopath
through a brain scan. He recalls numerous violent events in his past that did
not strike to him as having potential resulting problems. For example, he was enamored
with explosions as a children and eventually began building pipe bombs. He says
that there were times when he and friends almost burned down houses, but this
did not deter him from the excitement and obsession with explosives.
Data from this experiment suggested that the triggers of the
psychopath lay in the organization of the brain’s network. Specifically,
researchers found that psychopaths did not respond to the concepts of rewards
and punishments in the same way as the other participants. There was “abnormal
responding to punishment within the posterior cingulate and insula when a
preciously rewarded response was punished.” Psychopaths are not able to weigh
out potential positive and negative outcomes of their actions and only foresee
the positive outcomes. As a result, they do not anticipate the negative
outcomes or punishments and consequently commonly act out in unnatural ways.
The researchers
concluded that there may be specific intervention, that when administered
during childhood, can prevent the social distortions endured by the psychopath.
Most violent individuals exhibited criminal predispositions starting at an
early age. As a result these habits are reinforced within their brains for long
periods of time. From this experiment, researchers hope that by use of
interventions from early ages, these behaviors can be reduced and criminal
activity can be limited.
Research
continues to grow on the topic of psychopathy. Hopefully as more knowledge is
gained about the disorder, there will be remedies developed to help the people
ailed with it. Fallon did not find out he had the brain of a psychopath until
later on in his life and consequently questioned the meaning of many of the
events of his life. For this disorder to be remedied, psychopathy needs to be
thoroughly defined and comprehended. With more research about how these brain
patterns occurs, we can understand how and why psychopaths functions the way
they do.
