Violence Among Teens and Young Adults
Violence among teens and young adults nation wide appear to be on the increase and may as
believed by some be reaching endemic proportions. Is it simply bullying or is the violence
indicative of something much more involved? Is this problem as resent research may suggest be
related to brain chemistry and an immature prefrontal cortex and as such are we too quick to
blame adolescents for incidents we adults believe could have been easily avoided? Is it related to
cultural difference, stress, or a history of social conditioning? What can be done about this
increasing concern and who is responsible for the reverse of this trend?
Biochemical differences within the brain may in part be responsible for teen and young
adult violence. Since the birth of functional magnetic resonance imaging (f MRI) recent
comparison studies have pointed out a difference in the teen vs. adult prefrontal cortex of the
brain responsible for executive functioning that brings about reasoning skills, planning and
voluntary behavior. MRIs have shown in teens that the skull thickens but the brain is 90% that of
an adults. The brains over-all breadth is stable but the components change in size and shape.
There are also alterations in neurons that are involved in decision making, judgment and impulse
control. These studies have suggested an underdeveloped prefrontal cortex in adolescents and
young adults and as such brain function that support cognitive control of behavior are not yet
mature. (Beatriz Luna, director of the Laboratory of Neuro-cognitive Development at the
University of Pittsburgh). Leslie Sabbagh (science journalist specializing in medicine and
aerospace) states that in every day life general overtaxing of the prefrontal cortex may undermine
executive function, impairing planned behaviors and choices that suggest why adolescents exhibit
impulsive or thoughtless behavior. Conjointly, Luna comments it is easier for adults to suppress
bad responses to peer pressure then teens as adults are better able to keep themselves in line,
rather than succumbing to temptation. Susan F. Tapert, (associate professor of psychiatry at the
University of California, San Diego investigating spatial working memory in teens ages 12 to 14 and
ages 15 to 17) suggests that this age group becomes much less efficient when they are stressed
with overwhelming responsibilities. Further, adolescents who feel overwhelmed are inclined to
make bad decisions. Only at the end of adolescence, Tapert states, is spatial working memory
more efficiently distributed across brain regions.
Violent behavior as suggested by researchers Daniel Strueber, Monika Lueck and Gerhard
Roth (Hanse Institute for the Advance study in Delmenhorst Germany and at the Institute for Brain
Research at the University of Bremen) never erupts from a single cause. Rather it appears to resultfrom a complex web of related factors. Some of these factors appear to be neuro-chemically
inherited, some due to damage to the frontal cortex. Others may be anatomical and yet others are
manifest through childhood experience or environmental conditioning.
The greater gender at risk for outward physical aggression appears within males. In many
animal species, male aggression has been closely linked to testosterone levels. In humans, the
association seems slight however researchers have found significantly higher levels of

testosterone in violent offenders as compared with nonviolent offenders. Notably, of those
females who exhibit increased aggression they too have been shown to have higher levels of
testosterone. It is known that testosterone is subject to substantial fluctuation and increase for
example in males just prior to competitive sporting activities. This level remains higher for a
greater length of time among winners but seems to decrease rapidly among the losers.
Unremitting competition and notably conflict in general may accordingly permanently alter
testosterone levels. Commonly, in accordance with Strueber, Lueck and Roth male testosterone
levels seem to peak in the late teens and remain high until the mid-20s exactly the age group in
which male aggression and violence are most common. Low levels of serotonin known to be an
inhibitory and fear-reducing chemical in the brain may also be linked to antisocial and impulsive
acts of violence. Comparatively, those with decreased serotonin levels are also proven to suffer
from depression with among other symptoms that of impulsivity, irritability and fear.
Psychologist James Dabbs of Georgia State University suggests that biochemical
differences maybe genetic or behaviorally linked to environmental factors. As an example, the
most severe and early cases of abuse and neglect in childhood may have a permanent impactupon the reduction of serotonin levels within the brain that in turn may point to a greater risk for
predisposed violent and/or explosive behaviors. These psychosocial risk factors may include
serious deficiencies in early parent-child relationships such as failure to thrive cases, neglect,
physical/sexual abuse, inconsistent parenting, persistent parental conflict, break-ups, loss in the
family, parental criminality and poverty relations can over the course of time lead to severe
developmental disorders such as lowered impulse control, lack of empathy and reduced capacity
for resolving conflict. Because of diminished reasoning skills teens most often fail to appropriately
weigh risks against benefits. With a reduced capacity for conflict resolution and reasoning
adolescents and young adults may more readily turn to potentially destructive coping behaviors
such that of responding to peer pressures, cutting, violence, promiscuity, alcohol and/or otherdrug abuse in order to quell interpersonal conflict or to more greatly enhance feelings of well
being. More aptly they appear to choose impulsively greater more pleasurable gains such that
again of alcohol/drugs, cutting or promiscuity as hormones (endorphins) are released during a
period of development when the pleasure center (nucleus accumbens) of the brain is said to be
more well developed then that of the prefrontal cortex.
Understanding the limitations and capabilities of the teen and young adult brain is
imperative for education and psychological assessment. Current strategies for reversing the trend
of violence in teens and young adults within school and home settings seem incomplete and/or
may be inconsistently utilized. As we are all affected by the violence, I believe we are allresponsible for reversing the trend by taking a closer look as to whether we are contributing to the
problem or helping overcome it.
For now the following are empirically supported recommendations for helping adolescents
and young adults avoid unhealthy risks:

3/3
1. Create a de-stressed learning environment for children while they develop increasing
endogenous control.
2. Reduce and/or more closely monitor work loads such that of homework or multitasking
activities.
3. Protect those who are teased or those who may standout with learning disabilities,
cultural or behavioral differences through physical presents and intervention.
4. Teach empathy, tolerance, understanding and anger management.
5. Teach adequate communication and conflict resolution skill.
6. Encourage the use of intuition when reasoning skill capacity appears limited or
impacted by irrational consequential benefits.
7. Offer well reasoned arguments for resisting risky behaviors as well as factual evidence
and examples of social norms. Offer safer alternatives.
8. Remove or limit opportunities that promote risky behaviors such that of alcohol or drug
use. Implement a higher drinking age; limit the number of peers who can accompany young
drivers.
9. Encourage the use of self-binding contracts such as in not cutting, hurting self or others
or engaging in promiscuity or attending unsupervised parties.
10. Encourage the development of recognizing early warning signs that may signal
immediate or pending danger. before it is too late i.e. raising of voice, clenching of fists, tightening
of jaw, feelings of isolation, loss of appetite, insomnia, irritability, lack of concentration, feelings of
helplessness or hopelessness.
11. Encourage the development of healthy vs. unhealthy behaviors through exposure to
media that may be emotionally evocative.
12. Encourage the use of outside support systems such that of Human Service Agencies,
physicians, and therapists who can offer financial assistance/monitoring, pharmaceutical and
cognitive behavioral therapies.
13. When using discipline or implementing consequences, give back that which you have
taken in self-esteem or self worth by pointing out both the incorrect behavior as well as behaviors
that have previous been performed well.
14. Encourage the use of positive self-talk.
15. Get involved in your teenagers life. Stay involved despite their resistance, which are
often no more then attempts at protecting their pride/ego while seeking healthy independence.
