The
separation of adult and juveniles in the justice system was caused by a change
in ideologies regarding juvenile offenders.
Through increased research spanning multidisciplinary scientific fields,
it has become recognized that juveniles vary greatly in comparison to adults. These variations demand and justify
sentencing and correction treatment that is different for adult and juvenile
offenders. Juveniles differ mentally, psychological,
and socially in comparison to adults. Further
examination of these aspects outlines the significant differences between
juvenile and adult offenders, and the necessity to sentence each group accordingly.
Significant
neurological differences have been found between juvenile and adult offenders. During adolescence the brain has yet to fully
develop, unlike an adult’s. More
specifically the frontal lobe of the brain in adolescents remains
underdeveloped; the frontal lobe of the brain is responsible for regulating
decision making, problem solving, control of behavior, and emotions. (National
Institute of Health) An underdeveloped frontal lobe prohibits juveniles from
comprehending the gravity of their behavior, the consequences of risk, and
disables them from establishing long term goals. As a result of an underdeveloped frontal
lobe:
… adolescents tend to use a part of
the brain called the amygdala during their decision-making. The amygdala is a locus for impulsive and
aggressive behavior, and its dominance over the undeveloped frontal lobe makes
adolescents ‘more prone to react with gut instincts.’ In adult brains, the
frontal lobe offers a check on the emotions and impulses originating from the
amygdala. (Parker 49)
The Amnesty
International report provides a clear and obvious difference between the mental
development of juveniles in contrast to adults.
In addition, research has recognized that juveniles undergo rapid
neurological change and development during adolescents and these changes often
times occur before competent decision making is developed. (Rigby 1-8) Coinciding, according to an Amnesty
International report on juvenile offender’s mental development, “Neurological
studies show that children have physiologically less-developed means of
controlling themselves.” (Parker 47) It becomes apparent through research that
the juvenile cognition and neurological development is not fully complete
during adolescents; therefore, it is unethical to hold juveniles to the same
standards as adults when it has been proven that juveniles do not have the same
mental competency as adults.
In
addition to neurological differences, science has proven great psychological
differences between juveniles and adults.
The most noticeable psychological difference is juveniles’ inability to
reason with logic. Instead, juveniles’
emotions are the main influence in decision making. Especially in stressful situations juveniles
are more likely to reasons with emotions, such as fear, then with a logical
though process. (Parker 47) Another
psychological difference is juveniles’ inability to form and appreciate long
term goals. Instead, juveniles focus on
more short term goals, which greatly influences their decision making process.
(Parker 45) Psychological differences
are extremely similar to neurological difference because the brain is not fully
developed (neurological), therefore it is not capable of using logical
reasoning to make a decision (psychological).
However, these are not the only significant difference found between
juveniles and adults.
Another
significant area of difference between juveniles and adults is the social
development and environment. The lack of
mental development results in a lessened ability to logically reason, leads
juveniles to be high influenced by peer groups and peer pressure. Juveniles are more likely to engage in criminal
activity in a group than by themselves. (Rigby 5) While engaging in criminal activity in groups,
the level of criminality is easily escalated due to the lack of understanding
and inability to stop the situation with reason. According to the Prison Journal:
Juveniles are thus more likely than
adults to react with unplanned violence under the extreme duress of a crime
that goes awry—to fight rather than flee.
For juveniles, it would be more accurate to see the majority of these
crimes as situations that have gotten beyond their control and even full
comprehension.” (Johnson and Sonia 198-206)
Tied into the
underdeveloped neurological and psychological aspects of juveniles is the
inability for juveniles to control and comprehend social situations when facing
pressure from peers. In such cases,
rational adults are less likely to be influences by peer pressure, and more
likely to be able to stop and correct inappropriate behavior caused by peer
groups.
Neurological, psychological, and
social research combined proves the vast differences between juvenile and adult
development. These differences ethically
demand that juveniles be treated differently with the justice system,
especially considering that juveniles have been proven to respond well and
benefit from therapeutic treatment avenues over harsh sentencing. However, research also has acknowledged a
core group of juvenile offenders that are disproportionately responsible for
the majority of juvenile crime. This
core group, upon repeat offending, loses the defense of competence and
underdevelopment. After juveniles
offenders within this core group continue offending, they are usually charged
with harsher sentences resembling those of adults. At this point, once all other therapeutic
avenues have been exhausted and no sign of reform is apparent within the
juvenile, should juveniles be subject to adult sanctioning. In all other cases, the obvious differences
between juveniles and adults portray the need to sanction and treat juveniles
differently within the justice system.
