Many remember the notorious trial of John Wayne Gacy, a man
who strangled and killed numerous young men only to satisfy his sexual desires.
The image of law enforcement officials pulling out the victims’ corpses from a
crawl space in his home is forever engrained in some minds. Noted as a monster
and a killer clown, he was sentenced to capital punishment and further
executed. The public personally attacked his defense attorney, Samuel Amirante,
for seeking a sentence of life in prison. He argued that for the sake of research,
capital punishment should not be imposed: There is much to learn about
psychopathy.
Recently, studies have shown that psychopaths may not be as
evil as we think. There is a neurological deficiency that can partially explain
their behavior, and explain why Gacy was able to watch his victims strangle to
death without even a flinch. Accounting for twenty three percent of inmates and
one percent of the general population, psychopaths are characterized as
callous, impulsive, and unemotional. In the last decade, researchers have discovered
that these individuals contain a cognitive-affective deficiency. Specifically, psychopaths
exhibit an abnormal selective attention when presented with complex stimuli. In
other words, the individuals ignore cues that are unrelated to their goal, accounting
for Gacy’s emotional deficit. As the men struggled for air, his attention was
reallocated to the information pertaining to his goal. Similarly, cognitive-affective
deficiencies have also been noted in externalizers or individuals who exhibit
intense hostility and reactive aggression.
These individuals have impaired
executive functioning and overreact in emotional situations.
With this in mind, Dr. Baskin-Sommers used 103 inmates who exhibited
either psychopathy or externalizing traits to determine the efficacy of
cognitive remediation. Using the Psychopathy-Checklist Revised (PCL-R) the
subjects were grouped into psychopathy or externalizing subtypes. Half of the participants
were randomly assigned to training sessions that targeted their cognitive
deficiency while the other half were mismatched in treatment. Prior to training,
the subjects conducted an assessment session to determine if their scores would improve post-training. Once a week, for six weeks the inmates either received
cognitive training for psychopathy or externalizing. Tasks that have been
chosen to target psychopath’s selective attention included Reversal Learning,
Gaze, and Context Discrimination. Moreover, tasks that targeted the
overreactivity of externalizers included Breath holding, the Go-Stop Task, and
the Simon Task. After such training, the participants were given the same
assessment session to note any improvements.
Dr. Baskin-Sommers found that deficit matched groups only
showed significant improvement due to training. While those with mismatched
training, performed worse on the assessment as their deficiencies were
exacerbated by the training session. Interestingly enough, psychopaths with
matched treatment displayed a decrease in the number of correctional punishments received and matched externalizers displayed a decrease in severity in
misbehavior. This suggests that cognitive remediation may be effective.
Another study described in Medical News Today, revealed that psychopaths possess empathy, but
a neurological deficiency accounts for the fact that the emotion does not
always get triggered. Eighteen participants diagnosed with psychopathy were compared
to a control group of twenty six individuals. Principally, the subjects viewed
movie clips of characters who interacted in either a loving, painful, socially
rejected or neutral manner. The participants were then shown the same
scenes again but were asked to empathize with the actors to try to understand the
feelings that they were displaying. Subjects were placed in MRI scanners
in order to analyze their brain patterns as they viewed the interactions. The results
revealed that psychopaths did display less empathy as compared to control
participants. However, psychopaths were still able to empathize when asked to
understand the actors’ feelings. Moreover, the brain scans showed that psychopaths
displayed less activity in brain regions involved with their own emotions and
sensations, suggesting a neurological basis for decreased empathy.
What is significant is that with cognitive training,
researchers believe that psychopaths may increase their ability to experience
empathy. The article describes, “Therapies for psychopathic individuals should
focus on making their already-existing empathy ability more automatic in order
to prevent them from harming others” (Whiteman). As in the study conducted by
Dr. Baskin-Sommers, cognitive remediation may be the key in treating the
deficiencies that inmates display. Although initially criticized for this view,
defense attorney, Samuel Amirante, is now just one of many who recognizes the
importance of studying such abnormal behaviors. Understanding the deficiencies may decrease the harm imposed on
society.
