6 facts about crime and the adolescent brain
BY Emily Kaiser | May 15, 2013
[Time 2]
The criminal justice system needs to rethink the way it manages teenagers who misbehave, according to Laurence Steinberg, an adolescent brain development expert at Temple University.
Because the adolescent brain is still developing, the risks taken and mistakes made by young offenders may be more outside of their control than we think, said Steinberg.
"No one is saying that kids who commit horrific crimes shouldn't be punished," Steinberg told the New York Times. "But most in the scientific community think that we know that since this person is likely to change, why not revisit this when he's an adult and see what he's like?"
Steinberg is in the Twin Cities to speak at the University of Minnesota at a lecturetitled "Should the Science of Adolescent Brain Development Inform Legal Policy?"
Steinberg joined The Daily Circuit Thursday, Nov. 15 to discuss his research.
Here are six facts we gleaned from Steinberg's appearance on The Daily Circuit:
1. Adolescent brains have weak brakes
"One way to think about it is a kind of competition or balance between two different brain systems: A system that impels us to seek out rewards and go for novelty and excitement, sensation seeking, and then a brain system that really puts the brakes on impulses," Steinberg said.
"What we now understand about the adolescent brain is that both of these systems are changing during the course of adolescence. The reward seeking system is becoming more easily aroused, particularly during early adolescence, which makes kids seek and go after rewards. The braking system is still developing very, very slowly and it's not fully mature until people are well into their 20s."

2. Adolescents take more risks in groups
In Steinberg's lab at Temple University, researchers put people through a driving simulation and monitor their brain activity with MRI. The game involves a number of risk-taking scenarios.
"When adolescents are playing the game without their friends watching them, they don't play it any differently than adults do," he said.
The game player's friends are then brought into a room to watch their friend, but they can't interact.
"Just knowing that your friends are watching you doubles the number of risks teenagers take," he said. "If we look at adults, it has no impact on their behavior whatsoever."
When friends are watching, the brain activity changes too.
"There was much greater activation of rewards centers in the brain when the adolescent was playing the game being watched by his friends," Steinberg said. "In adults, the brain activity looks exactly the same when they are playing alone versus playing with their friends watching them. It leads us to think that something is going on when teenagers are with their peers that makes them especially sensitive to reward."
3. The behavior-governing prefrontal cortex is morphing
"What happens during adolescence is that this part of the brain becomes a more efficient tool through changes in the anatomy of the prefrontal cortex, but also it becomes a better connected part of the brain in its ability to communicate with other brain regions," Steinberg said. "The period of time during which this is happening really extends from pre-adolescence all the way into the mid-20s."

4. Adult guidance makes a difference
"If we're talking about a child who is at a stage of development where his own self-control is still immature and still developing, one thing that can help him is to have self-control imposed on him by other people," he said. "That's a role parents play that helps protect their youngsters from engaging in risky and reckless behavior."
5. Ninety percent of kids who break the law during adolescence don't become adult criminals
"A lot of the misbehavior that adolescents engage in is transient," he said. "It happens during adolescence partly as a function of the immaturity that is characteristic of the period and then it goes away without any intervention whatsoever."
6. Teen offenders are too often treated like adults when they hit the justice system
"It is not that unusual for our justice system to criminalize what I think most of us would consider to be, you know, stupid adolescent behavior," he said. "They come into contact with a system that just has stopped viewing them as what they are, which is kids. They are not adults. We need to go back to an earlier point in our history where we had a separate juvenile justice system that didn't have such a porous border with the adult system, which is what we have right now."

Punishment for juvenile crime – should it be different?
BY Paul Samakow | May 18, 2014
[Time 5]
Two teenagers shot and killed a college baseball player out for a jog in Oklahoma last August. They explained they committed the murder because they were just bored.
Juveniles who commit crimes have legal protections that include lighter sentencing than adults would receive in the same circumstances. Discussions continue about the appropriateness of that leniency each time a horrible crime is committed by a teen.
The Supreme Court has trended toward the more lenient position, and most recently, California’s high court ruled in the same direction.
In 2005, in the case of Roper v. Simmons, the Supreme Court ruled that the death penalty for those under 18 was cruel and unusual punishment and thus unconstitutional. Life in prison, without parole, thus became the most significant punishment a juvenile could suffer for committing any crime.
In 2012, the Court ruled that mandatory life sentences for juveniles also violated the 8th Amendment’s protections against cruel and unusual punishment. The thinking was simply that juveniles are different than adults. The Justices appreciated that a juvenile’s brain is not fully developed.
The ruling means, for juveniles, that a judge cannot simply look at the mandatory sentence for a given crime and impose it; rather, when sentencing, judges must look at and consider that a younger person is different than an adult.
“Youth have less responsibility for their actions than adults and greater prospects for reform,” the court concluded.
Reformers of juvenile sentencing say that a younger person’s brain is not fully developed. They are correct.
Peter A. Weir, a former judge and now a prosecutor in Colorado, offered a tougher view in the November 13, 2013 Denver Post. He said that some juvenile offenders commit crimes so serious and so heinous that public safety mandates — and justice demands — full accountability in our criminal justice system.
Weir counters the argument of those who say this is unfair and unjust: “reform experts tell us that three-quarters of adolescents lack the decision-making abilities of adults, thus one-quarter of juveniles can function in an adult manner.” Weir further notes that experts acknowledge that they cannot apply general concepts of a developing brain to the activities of any specific person.

The Colorado case that led Weir to his comments involved a young man just shy of his eighteenth birthday. The young man hunted, kidnapped and killed a ten-year-old girl. Weir says the murder was thoughtful, deliberate and cunning in its planning and execution. The “juvenile” was sentenced to life in prison plus 86 years.
Last month, California’s Supreme Court overturned a longstanding punishment “presumption” that would impose life without parole for juveniles convicted of certain murders.
California’s court ruled that trial courts “must consider all relevant evidence bearing on the distinctive attributes of youth, including hallmark features of adolescence such as immaturity, impulsivity, and a failure to appreciate risks and consequences.”
The ruling forces judges to consider those factors before imposing the harshest of sentences on youth.
Elizabeth Calvin, a senior advocate for children’s rights at Human Rights Watch, said about the California ruling:
“The court has recognized today what every parent knows – kids are different and are capable of tremendous growth and transformation. Now, it is up to judges and state legislators to ensure that all child offenders have a meaningful chance to work toward rehabilitation, to periodically demonstrate their achievements, and, if merited, to earn their release from prison.”
Richard Bonnie of the University of Virginia School of Law and Elizabeth Scott of the Columbia Law School, in the journal Current Directions in Psychological Science, argue that “new scientific insights can and should guide legal decision making about teens as a group, but that it’s far too early to look for scientific assistance in individual judgments”.
“One problem is that law and science view human development quite differently.” As Bonnie and Scott note, “the law basically divides people into minors — vulnerable and incompetent–and adults, who are autonomous and responsible. But psychological science has a more nuanced view of adolescence as a separate stage, between childhood and adulthood.”
They say that this view “is supported by neuroscience, which shows that the frontal cortex — the seat of judgment, self-control, and sensible planning — matures very gradually into early adulthood. It is out of sync with the early development of the emotional brain, and as a result there is a gap between early sensation seeking and later self-discipline.”

[The Rest]
In 2012, a theory of the juvenile mind was offered from the world of psychological science, furthering the “there is a difference” theme. Jean-Louis van Gelder, of the Netherlands Institute for the Study of Crime and Law Enforcement, argues that juveniles suffer from conspicuous shortsightedness. He says that young people appear overly focused on immediate rewards such as money, sex, stimulation, and that they have little regard for potential later consequences. Van Gelder says this seems obvious in a way, and that is why juveniles commit crimes and end up in jail.
Van Gelder asked “why?” and decided to test for the concept that juveniles suffer from a specific cognitive deficit, one that makes it very difficult for them to imagine their future selves. He ran multiple experiments. He concluded that “the vividness of the future self is the key to making prudent decisions in the here and now — and diminishing criminal propensity”.
Understanding criminal mentality is the subject of countless studies, books, and seemingly endless analysis by scientists, criminologists, psychologists, legal scholars and others concerned with decreasing crime. Whatever the reason for criminal behavior, it is clear that a blind punishment rule that cannot address individual circumstances and differences between a juvenile and an adult is inappropriate.
Parents catch their kids, ages 17 and 11, doing the same “bad” thing. Older kid gets punished harsher. There is a need to consider everything when punishing someone.
A juvenile criminal two months shy of age 18 should not necessarily be treated with lenience. Mr. Weir, the U.S. Supreme Court, and the California Supreme Court are all correct.
