Teenage Brain Development: Its Impact on Criminal Activity and Trial Sentencing

Keywords adolescent brain development; decision-making; impulsivity; rehabilitation; harsh punishment; maturity; juvenile justice

THE DEVELOPMENT OF A CHILD'S BRAIN AND HOW IT AFFECTS A TEENAGER’S reasoning skills when making tough decisions and acting upon them seems to be a gray area in the legal community. Adolescence is a transitional period during which a child is becoming an adult. While there has been some limitations and restrictions to what children and teenagers can do— such as voting, legal alcohol drinking, enrolling in the military, among other limitations—when it comes to how to prosecute and sentence a minor, there are still circumstances where the legal system could demand to treat them as fully functioning adults. Why is this worrying? Mainly because recent discoveries in neuroscience have shown that “a teenager’s brain does not resemble an adult’s fully matured brain until they reach their early [twenties].” Basically, an adolescent brain is different from an adult brain. What this means is that the adolescent brain is constantly developing into an adult brain, and the “risks taken and mistakes made by [teenagers] may be . . . outside of their control . . . .” These risks and mistakes come from impulsive actions, poorly measured decisions, and the peer pressure that teenagers suffer from; proving that at that stage the brain is still very malleable. Thus, teenagers and their developing brains, act according to impulses, and lack of thought for the consequences of their actions, similar to acting in the heat of the moment. These scientific discoveries have helped the psychiatric and legal community understand why teenagers have a higher risk of committing crimes such as: shoplifting, assault, and even murder.

According to Michael N. Tennison, minors “start out with little or no capacity for responsibility and gain it gradually but globally as they mature; if they engage in serious or adult-like crime, however, then they must be capable of experiencing adult-like consequences.” We are living in a period of time when people who are between the ages of fourteen and twenty-four—a range where the brain is at the peak of its development—commit many crimes yet most of which are treated as adult-like crimes, with adult-like punishments. While it is true that teenagers know right from wrong, and that they should be held responsible for their behavior when they violate the law, courts should analyze adequate punishments where teenagers are able to reform and rejoin society.

New findings in the field of juvenile developmental neuroscience have contributed in recent United States Supreme Court decisions regarding serious crimes made by teenagers. Below, I will explain in detail, the process of teenage brain development, the different ways this influences a teenager’s decision- making and how in many occasions this leads to criminal behavior, followed by how the United States Supreme Court has applied these neurobiological discoveries.

I. HOW AND WHY A TEENAGER’S BRAIN IS A WORK IN PROGRESS?

The answer to this question will be answered by explaining the adolescent brain, its development, and how this process affects a teenager’s behavior and reaction to certain situations.

A. The Adolescent Brain

The adolescent brain mostly ranges from the age of eleven to twenty-four. During the teenage years, the brain is in constant change; it is a time of significant growth and development. This process—also known as puberty—is where a child develops into an adult. At this stage, the adolescent brain and thus, the teenager, “will do very stupid things in a very impulsive way”, which, to paint a picture, means that they are going through a rollercoaster of emotions that affects their decision-making abilities. It is at this stage where a person starts to resemble what professor Laurence Steinberg compares to a “car with a good accelerator but a weak brake.” What professor Steinberg means with this metaphor is that the adolescent brain has strong impulses that the teenager cannot seem to control and, like a car with weak brakes, it is bound to crash. Basically, the adolescent brain, due to “possessing less information” prevents teens from analyzing risks and, instead, “focus[es] on short-term gains rather than possible long-term losses . . . .”

During the adolescence, the teenager is in the process of “developing an integrated sense of self, including individuation, separation from parents, and personal identity.” It is during this process that the risky behavior starts. However, this is an experimentation stage that does not tend to “extend beyond adolescence,” and seems to seize once the personal identity “becomes settled with maturity.”

According to experts in the field, the adolescent brain can emotionally be divided into two competing systems. One system is a thrill seeker, a type of adrenaline rush that seeks the praise of others and that “craves sensation and excitement” regardless of the risk. The second system is responsible for “put[ting] the breaks on impulses,” and is also known as the analytical risk measuring system. Accordingly, these two systems influence how teenagers and young adults react and behave in certain situations. As previously mentioned, these systems arise from the development of the adolescent brain. Thus, as professor Steinberg has stated, “these systems are changing during the course of adolescence.” This change will eventually bring a balance and proportionality to the brain system where the reward-seeking thrill will hold off until the consequences of such actions or behaviors have been properly analyzed.

The risk-taking and the desire for peer approval tends to be prominent at the ages that range from fifteen to eighteen, ages when most juvenile criminal activity is reported. As mentioned, this process in the adolescent brain may last until the late twenties, which is why even young adults (who are compared with fully grown adults) are still shaping and developing their judgment and impulse control. For these reasons—risk-taking, rewards, and novel exciting situations—adults tend to denominate teenagers and young adults as what Michael N. Tennisson & Amanda C. Pustilnik identify as dumb, that is, people who take unreasonable risks and making bad decisions. However, as Dr. David Fassler has stated on adolescent brain development:

[This] doesn't mean adolescents can't make a rational decision or appreciate the difference between right and wrong . . . [i]t . . . mean[s], [that] when confronted with stressful or emotional decisions, they are more likely to act impulsively, on instinct, without fully understanding or analyzing the consequences of their actions.

It can therefore be inferred that teens cannot really control their impulses. Regarding the need to be rewarded and praised, Professor Laurence Steinberg has stated, "this isn't a choice that kids are making to give in to their friends . . . biologically, they're more vulnerable to that." Hence, as maturity sneaks in, people will develop better control over their impulses and use a better reasoning" approach to make better judgments, aiding in the need to make careful decisions when stressful situations arise.

B. Brain Development

Thanks to Neuroscience and technology, significant evidence to explain the brain structure and function during the teenage years is now available. First of all, neuroscience confirms that adulthood and, thus, brain development, arrives in the late twenties. The differences between adolescent and adult reasoning and behavior can be observed and studied through brain development. Secondly, technology in brain imaging, such as Magnetic Resonance Imaging (hereinafter, "M.R.I."), has provided "the opportunity to safely track the development of brain structure, brain function, and brain connectivity in humans."S M.R.I. has helped the scientific and sociological field support their findings and conclusions regarding what was previously described about the adolescent brain.

i. Structural Brain Development

The human brain has reached approximately ninety percent of the adult size by the time a child is six years old; however, its development is still in the early raw stages of development. Therefore, it is pertinent to say that the teenage years are "a critical period for brain development" and not brain growth. With brain imaging, scientists have been able to study the process of brain development.

Basically, this development revolves around the brain's wiring. Beginning with the brain's axons, which are "long, thin tendrils that extend from the cell and transmit information," getting wrapped (like insulation) around myelin (the white matter in the brain), which contributes in the growth on brain connectivity. The key to what myelin does during the adolescence is that it doubles its amount in the brain, thus, in the axons. These doubled amounts affect the speed at which messages are sent through the brain, meaning, "impulses or messages can pass at far higher speed along the axon," thus affecting someone's primary learning abilities. The myelination process begins from the back of the brain all the way through the front, which is the area involved in “decision- making, planning and self-control,” ending with a matured brain and person. While the myelination process is happening, the dendrites, which the axons send information to, grow branches all across the brain, allowing for better communication throughout the brain. Then, “[t]he synapses, the chemical junctions at which messages are passed on, grow stronger if they are used often.” What it is meant by if they are used often is that if some synapses are not used, they will eventually disappear, causing pruning. The pruning “causes the brain’s cortex—the outer layer of ‘grey matter’ which does much of our complex, conscious thinking—to become thinner and more efficient.” While that is happening, the corpus callosum (responsible for joining the two hemispheres, left and right), “thickens, improving the efficiency of communication both between and within the brain’s hemispheres.” With this, stronger links develop connecting different regions in the brain.

It is important to remember that brain development begins on the back of the brain and moves all the way to the front. Why is it important? Mainly because “regions that involve primary functions, such as motor and sensory systems, mature earliest compared with brain regions that integrate these primary functions for goal-directed behavior.” The motor and sensory system development, as mentioned, is the first thing to develop in the brain, and it is also located in the back of the brain, which is why this is the first thing our brains work on. The last thing we develop is, the constantly evolving, pre-frontal cortex. The pre-frontal cortex is the “defining feature of our human brain;” this is the part of the brain that is responsible for the risky behavior, poor decision-making, and social-rewarding activities teenagers engage in. Brain development, specifically the pre-frontal cortex, will not fully be developed until late twenties or even later, which is why “risk-taking, [peer pressure] and impulsive behavior are more common among teens and young adults,” because teenagers don’t fully have the capacity to weigh pros and cons.

ii. Brain Development and a Teenager’s Day-to-Day Life

The previously described brain developments, which take place during the teenage years, can be noticeable in a teenager through “behavioral, cognitive and emotional changes,” which reciprocate to poor judgment, quick reactions, and long journeys to find themselves. The timing of these changes, which arise from puberty and maturing, “underlie many aspects of a [risky] behavior.” It is therefore imperative to discuss these changes on their own, in order to have a better understanding of why brain development influences in a teenager’s behavior.

Thanks to brain imaging technology, such as M.R.I., researchers have been able to study the maturation of the pre-frontal cortex and its relation to cognitive behavior in teenagers. Throughout their teenage years, adolescents: (1) “lack mature capacity for self-regulation in emotionally charged contexts, relative to adults and children;” (2) “have a heightened sensitivity to proximal external influences, such as peer pressure and immediate incentives, relative to adults,” and (3) “show less ability to make judgments and decisions that require future orientation.” Basically, this pattern is what makes a teenager prone to risky behavior that results in some sort of reward, even if it is detrimental to others or him/herself. The maturation of these cognitive patterns will mold the teenager into an adult capable of processing new information, knowing the difference from right and wrong, and improving their decision-making skills.

As stated, decision-making is part of the brain development related to cognitive behavior, however, it is also “highly influenced by emotion.” The aforementioned rewards that adolescents highly search and desire, although being part of a cognitive system, are also derived from an “emotional regulation” that result in risk taking situations. During brain development, many structures are—at the same time—involved in processing emotions (such as: fear, anger, excitement), controlling impulses (such as: motivation and survival), and “feelings of pleasure that reward behavior” (such as: food, money, and signs of appreciation). These structures are located in the limbic system, which is located in the cerebrum. For example, the nucleus accumbens is associated with the need to be rewarded and praised by others; it acts by providing some sort of goal- oriented thirst, whether favorable or harmful to the acting teenager. At the same time, the amygdala and hippocampus are linked together to control how someone reacts to fear, thus, having an effect on emotional response. That reaction, then, remains in the hippocampus, creating an emotional memory. Nonetheless, even though those brain structures influence the emotional behavior of a teenager, neurotransmitters, such as dopamine, have a high involvement in the regulation of emotions and behavior during adolescence. Researchers have stated that dopamine has “been found to be involved in the brain’s response to novelty and rewards in the environment as well as risk-taking behavior.” Based on this, experts have been able to understand and explain the adolescent brain and its involvement with adolescent behavior, “such as quickness to anger, intense mood swings, and making decisions [based on] ‘gut’ feelings,” among others.

II. BRAIN DEVELOPMENT AND CRIMINAL ACTIVITY

As described above, the study of brain development has helped understand why teenagers engage in risky and, somewhat, delinquent behavior. M.R.I. studies have led researchers, from a biological perspective, to believe that depending on the stage of brain development, teenagers will not think properly before taking a risk and will rather act on impulses. When teenagers face situations where they have the time to process what is happening and their surroundings, they will probably be able to “distinguish right from wrong” and react like an adult would; however, when faced with an emotionally stressful situation and with incomplete information, basic emotional sensations will drive an adolescent to react irrationally and impulsively. For example, Dr. Fassler explains this impulse by explaining the likelihood of an adolescent to commit a crime: “an anxious adolescent with a gun in a gas station or a convenience store,” he then adds that the teenager “is significantly more likely to pull the trigger than an adult . . . under the exact same circumstance.” Essentially, it can be said that, depending on the situation, teens are “capable of reasoning about the possible harm or benefits of different courses of action”, and are therefore able to pull the brakes. However, sometimes the situation prevents them from weighing the risks involved. It is pertinent then to consider the circumstances the teenager was going through, in order to get a better understanding of what he was feeling and thinking prior to making a decision.

In order to have a better understanding of why adolescents make irrational decisions that lead to delinquency, researchers have come up with two types of cognitions: hot and cold. Basically, these are categories for what was previously explained on teenagers measuring and taking risks based on the situation they are facing and how much time or information they have. Researchers describe hot cognition as conditions where teenagers face “high arousal and intense emotion” that leads to poor decisions. On the other hand, cold cognition relates to mellow situations where teens go in the right direction of the law. Therefore, based on brain development research, “we should expect some irrational, emotion-driven [and possibly delinquent] behavior from [teenagers, since] it is not until their late twenties that it is reasonable to expect them to have the brain development necessary to behave like fully rational adults.”

Below, there are several factors which, together with the development of the brain, can contribute to teenage delinquency.

A. Peer Pressure

Why does the presence of peers interfere with self-control? Why do teenagers feel the need to be praised by their peers, thus engaging in risky situations? As I explained before, the pre-frontal cortex and the limbic system are the last structures to develop in the brain. They regulate emotions and decision-making, resulting in the process of self-control. Therefore, during the adolescence, teenagers are less likely to control impulses, plan ahead, or weigh the pros and cons of different courses of action. Thanks to M.R.I., researchers have "discovered that the peer [pressure] effect was ... due to the impact that peers have on adolescents' reward sensitivity".

Professor Steinberg has created a process that monitors brain activity by putting people through a simulation involving a series of risk-taking scenarios. It consisted on teenagers playing a game. First, without their friends, to which Steinberg noticed that "they [didn't] play it any differently than adults do." Then, with their friends present in the room without interacting with the teenager being monitored, Steinberg noticed that in the M.R.I. "there was much greater activation of reward centers in the brain when the adolescent was playing the game being watched by his friends.» He explained this stating that when a teenager has their peers as spectators, the risks will double. This M.R.I. analysis led Professor Steinberg and his fellow researchers "to think that something is going on when teenagers are with their peers that makes them especially sensitive to reward."

Consequently, jurisprudence has shown that teenagers will commit a crime in a group because the presence of peers stimulates the "reward centers of the brain which may increase risk-taking.” But, how do violence, peer pressure, and teenagers all fit into the equation? Simply put, teenagers by themselves rarely resort to violence in order to resolve a conflict; however, when peers are present, “adolescents are [prone] to resort to violence to resolve the conflict." Thus, the equation seems to be that teenage violence results from the combination of the need to be accepted and rewarded by peers. Doctor Alice Sterling Honig explains this as a type of “triumph of physical power [that is] glorified and held up" by their peers. This is, therefore, more proof that peer pressure highly influences a teenager at times of applying common sense and in acting impulsively. The adolescent’s perspective of right and wrong depends on what their peers think.

B. Parental Guidance

Why is parental guidance so important during brain development? Because during the maturation of the pre-frontal cortex, the cognitive functions are in full development mode, and therefore, are very involved in behavioral control. During this adolescent stage, parents should not overprotect their children, but “help [them] through this period by listening and offering support and guidance.” According to prison guards, many teenagers at juvenile detention centers end in prison because of lack of restrictions from their parents. Steinberg agrees with this, and he specifically stated that when “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 [the child] is to have self-control imposed on him [or her] by other people.” By this, he meant that parents have roles that, when taken seriously, will result in the guidance of their children and in the prevention of risky and reckless behavior.

There is extensive research regarding parental support and teenage delinquency. Scholars of this subject have stated that “[p]arental behavior can affect the occurrence of delinquent behavior in three main ways: hostile and coercive family processes, parenting styles and practices, and family modeling and socialization about risky behaviors.”However, these are not the only family related factors that influence teenage delinquency. Ultimately, it all comes down to the type of caregiving the child receives before and during the adolescence. Homes with involved, authoritative, and nurturing parenting will most likely raise a teenager who will not engage in delinquent behavior. However, “[d]isengaged parenting raises the risk for adolescent [behavioral problems] due to the absence of emotional bonding.” The risk of parents not being present (in this context, not being present means being disengaged) in a teenager’s life could lead to antisocial behavior or a group of peers with deviant views that will result in the commission of a crime.

A research on parenting and delinquency found significant links between “all parenting dimensions and delinquency but the magnitude of the related on the particular parenting dimension.” Their research consisted on gathering information of different parenting perspectives and analyzing its impact on teenage delinquency. As it turns out, their findings “revealed that negative aspects of support including rejection, hostility and neglect and psychological control had the strongest links to delinquency.” But what caught my attention— and which I believe to be pertinent to this article—was that “[a] lack of support had a relatively strong link to delinquency if that parent and child were the same sex.” If we take this as true, it could be said that children are prone to identify and have a better relationship with the same sex parent; thus, abandonment by the same sex parent will probably cause the teenager to rebel. Following that line of thought, lack of paternal support in a boy’s growth, for example, will probably result in the boy growing up without a father figure, causing him to resort to an outside male figure that might lead him to a negative, delinquent life. According to Walter R. Schumm, “[w]ith respect to conduct problems, as reported by parents on the [Strengths and Difficulties Questionnaire] scale [recent research has] not [found] significant differences between the children of same-sex and heterosexual parents.” However, because of sampling limitations, very little is known about same-sex families and its links to delinquency and there is a need for high-quality research in this area.

III. CRIMINAL PUNISHMENT & JUVENILE DELINQUENCY

It has long been established that a punishment should be proportional to the crime. According to this, how people are punished should be equivalent to their involvement during the commission of the crime, thus harsher punishments tend to be applied for the most serious crimes. The Puerto Rico Penal Code (hereinafter, “Penal Code”) establishes that punishment may not “attempt against human dignity” and will be “in proportion to the seriousness of the crime.” The Penal Code also states that the punishment should be imposed to: (1) protect society; (2) deter future crime; (3) rehabilitate the offender, and (4) punish according to the personal culpability of the criminal offender (retribution). However, regarding juvenile delinquency and punishment, adolescents are driven by peer pressure and impulsivity, so they are “less deserving of harsh punishment.”

There has been an ongoing debate on whether teenagers should be prosecuted in juvenile courts or as adults in the criminal justice system. The way a teenager is tried and prosecuted will have serious life changing repercussions in the course of their future. The process will have a huge negative impact because the adolescent brain is at a developmental stage where it is vulnerable and susceptible to be easily influenced by hardened criminals at adult prisons, which will prevent the adolescent from reforming.86 However, legislators in the United States have made policies that facilitate the prosecution of teenagers in the adult system. Such is the case that young offenders under the age of eighteen that have been charged as adults spiked between the years 1990 and 2010, where “the number of juveniles serving time in adult prisons . . . increased by almost 230%.” Charging kids as adults will make them think that the justice system has given up on them and their “stupid adolescent behavior.” The courts’ determination to prosecute a teenager in the adult system is based on the harm caused, and not the teenager’s age, therefore leaving aside their degree of maturity into account. Their reasoning is that “if a [teenager] causes serious harm, then he or she is not truly a child but rather an adult-like criminal in a child's body.” This flawed reasoning promotes biased and unfair judging and sentencing. Because of this, courts should analyze which punishment makes for turning a delinquent kid into a responsible citizen. However, at times when courts are at a crossroad between certain policies that requires them to act in a certain way and decide on objective and proportional punishments, there tends to be no room for discretion. At this pivotal point, it is up to policy makers to focus on a criminal justice reform in order to deal with juvenile delinquency and, thus, determine adequate punishments to minors who commit illegal activities.

A. Retribution

Believers of this punishment see it as a way to proportionally punish the wrongdoer, even if it doesn’t “result in a reduction [of the] crime.” Retribution stays focused on the commission of the crime and justifies the punishment based on the magnitude of the crime at the time it was committed. Juvenile cases with serious crimes are usually seen in regular adult courts, which result in adult-like punishments. As previously discussed, teenagers do not think, nor react, like adults. However, courts have, on occasions, given harsh punishments to criminal offenders for actions done during their teenage years. Retribution’s main goal is to deter the crime for which they are punishing. The thing is, this punishment is expensive, and there is no guarantee that it will deter future crimes. To get a better understanding of this, increasing a sentence of ten years to twenty years seems rational, however, “the cost of administering the more severe penalty is very high.”

It is then fair to say that when it comes to criminally punishing a teenager who acted with an irrational impulse because of the reward he/she might get for committing a crime, or who simply did not conduct a cost-benefit analysis, retribution will not necessarily deter others from committing the exact same crime or another far worse. Thus, imposing these harsh penalties on teenagers will cost the state a lot more, and it is not likely that the expected deterrence effect will, in fact, deter the adolescent whose brain is still not developed and will likely be “more impulsive and less reflective in their behavior.”

B. Rehabilitation

People who strongly support retribution criticize rehabilitation because the theory removes the analysis of punishing based on what the criminal deserves and “consider[s] only what will cure him,” thus makes him/her a good citizen. Rehabilitation consists of the reformation of the wrongdoer instead of imposing a sense of fear and a will to hurt the criminal because it is equal to the crime committed.

When applied to juvenile situations, we already know that “the brains of adolescents are biologically and developmentally different from the brains of adults.” It is mainly because of this that it can be implied that teenagers “are more likely to mature and change over time, enhancing the possibility of rehabilitation.” Because of this reasoning, experts in child development consider “that rehabilitation works better for juveniles than for adult offenders.” For example, a guilty fourteen-year-old murderer will have matured by the end of his teenage years, and during those maturing years he could be responsive to rehabilitation; it is different with an adult murderer who is set in his own matured ways.

C. Retribution vs. Rehabilitation in Juvenile Punishment

It is conflicting to embrace the fact that “juvenile court proceedings are aimed very much at rehabilitating [adolescents], while the adult system has become increasingly focused on retribution.” This being so, it is pertinent to reform the way the adult system, and thus, the justice system, punishes teenagers. Kids at the time of the commission of the crime, as explained above, act by impulse and without analyzing it’s consequences of their possible; actions and risks this makes deterrence likely to fail. It will fail because at the stage their brains are at, teenagers will continue to act recklessly without mediating the consequences; hence, a harsh retributive punishment will not deter future crimes. “Teens are less likely to weigh the prospect of future punishment relative to immediate reward.” Meanwhile, rehabilitating a teenager is a real possibility since they are in constant development. Teens are highly influenced by others; by giving them a chance to rehabilitate they can reform and thus, “pose a lower risk of recidivism and need not be incapacitated for life.”

We must remember that, even though the goal is to punish and deter the crime for which a teen is being punished, this is happening during the adolescence. This means that it happens due to the immaturity (and sometimes, lack of guidance) a person goes through, which eventually fades. Professor Steinberg stated that “only [ten] percent of serious juvenile offenders become adult criminals." Which is why courts should consider the age and maturity and lean towards a lesser punishment for juvenile delinquents for them to be able to participate in vocational training and rehabilitation programs.

IV. TEENAGE BRAIN DEVELOPMENT SUPREME COURT JUVENILE CASES

A. Roper v. Simmons

In Roper v. Simmons, Christopher Simmons was a seventeen-year-old kid in Missouri when he committed a murder after a burglary. Alongside a friend, he broke into the victim’s home, tied her up and pushed her from a bridge into a river, causing her to drown. His friend testified against him saying the crime was planned and premeditated, and Simmons was found guilty. At that time, State law required that when a teenager committed a crime like murder, he must be tried as an adult. The lower court told the jury to consider two things: Simmons age at the time of the event as a mitigating factor, and death penalty. The case reached the Supreme Court of the United States, where the majority went State- by-State analyzing juvenile death penalty, and decided against it for individuals under the age of eighteen at the time of the offense, concluding that the Eighth Amendment rejected such punishment for minors. They reached this consensus by analyzing Simmons’ age and how teenagers have a less developed brain and cognitive skills—compared to adults. Based on this, the Court noted three factors that demonstrate that adolescents can’t be placed in the same level of adult offenders that are subject to death penalty. The first factor was that a “lack of maturity and an underdeveloped sense of responsibility . . . found in youth more often than in adults [leads to] impetuous and ill-considered actions and decisions.” The other factor that the Court considered was that “juveniles are more vulnerable [and] susceptible to negative influences and outside pressures, including peer pressure.” The third determining factor was that “the character of a juvenile is not as well formed as that of an adult. The personality traits of juveniles are more transitory, less fixed.” For the purpose of this article, this third factor supports the main idea that teenagers, if given the opportunity torehabilitate, will reform. The Court specifically stated that:

The reality that juveniles still struggle to define their identity means it is less supportable to conclude that even a heinous crime committed by a juvenile is evidence of irretrievably depraved character. From a moral standpoint it would be misguided to equate the failings of a minor with those of an adult, for greater possibility exists that a minor's character deficiencies will be reformed.

These factors diminished Simmons’ culpability and justified abolishing deathpenalty for teenagers. Furthermore, these factors, while lessening culpability, also support the idea that harsh punishments will not deter adolescents fromcommitting crimes; hence, retribution is not appropriate.

B. Graham v. Florida

Graham v. Florida started with Graham committing an offense at the age of sixteen. He was charged as an adult and he entered a plea deal in which he did jail time and probation. During his probation, Graham was arrested for an alleged involvement in a shooting. At the age of eighteen he faced a different judge, who sentenced him for violating his initial probation." The judge scolded Graham for not taking the advantage to turn his life around, determined that he had an escalating pattern of crime that proved that there were no other sentencing options, and proceeded to sentence Graham to life in prison without the possibility of parole. In this case, imposition of a life sentence without the possibility of parole was for a minor who had committed armed burglaries and robberies. The Supreme Court repeated the scientific analysis used in Roper, and established that states cannot impose a life sentence without the possibility of parole to a minor who did not commit murder. ° The majority added that brain science--as Graham's Amici Curiae pointed out-suggests that there are fundamental differences between juvenile and adult minds. Following this line of thought, the Court focused on how "parts of the brain involved in behavior control continue to mature through late adolescence. Thus, this developmental difference, the Court figured, means that a juvenile's brain is constantly changing, therefore they have a bigger chance of change than adults, resulting in actions that will not constitute "irretrievably depraved character" as it tends to happen with adults. The Court also noted in the Amici that, these differences "also put|s juveniles] at a significant disadvantage in criminal proceedings. This increases the risk of error in assessing their culpability, because it impairs youths' ability to understand legal proceedings, to communicate with counsel, and to make legal decisions. The Court found that the punishment was too harsh, and with the lessening culpability acknowledged from Roper it was held that retribution and deterrence were inappropriate. Additionally, the Court added that the harsh punishment prevented the possibility of rehabilitation. With this rationale, it can be implied that, teenagers that commit serious crimes are not hopelessly lost. They just need to feel the possibility of getting out as a new reformed citizen, and to sentence a teenager to life in prison without the possibility of parole prevents them from doing so.

The dissent by Justice Thomas, joined by Justice Scalia and Justice Alito, focused, in part, on the relevance of science and juvenile punishment. Specifically, they argued how the majority sided with the Amicus’ brief on the differences between “adolescents for whom antisocial behavior is a fleeting symptom and those for whom it is a lifelong pattern.” They relied on a study, not cited in the Amicus brief. The study was an older 1993 paper, published well before the real advent of modern neuroscience. However, this study was not contrary to what was stated by the Amicus regarding antisocial behavior, it basically reaffirmed it. What is true for adolescents is that their brains can be molded. They are in a period of development. What the majority wanted to assert was that not all adolescents guilty of even major crimes are hopelessly lost.

C. Miller v. Alabama

In Miller v. Alabama the Supreme Court of the United States consolidated twoappeals, one of which involved a fourteen-year-old boy who participated in a robbery in which his accomplice killed an employee of a store. Although the prosecutor had the discretion to prosecute (or not) the minor as an adult, after being convicted as an adult, the only sentence available was life without the possibility of parole. The case also involved a fourteen-year-old boy who had killed a victim in the process of another robbery. The state juvenile court sent the case to an adult court, and the minor received a mandatory life sentence without parole. The Supreme Court declared these sentences unconstitutional noting the diminished culpability and the likelihood to reform. They based their position on the same scientific analysis cited in Roper and Graham. The Court held that the neurological—scientific—factors established in the previous cases had becomestronger. Some factors that this Court acknowledged from Roper, were that only a“small proportion” of teenagers that commit any illegal activity, will continue to engage in this problematic behavior. The Court noted that Graham stated continuing scientific developments that showed significant brain differences between adults and teenagers, specifically parts “involved in behavior control.” Another factor that the Court considered, according to the Amicus Curiae by the American Psychological Association, that adolescent brains are not yet fully mature in regions and systems related to higher-order executive functions such as impulse control, planning ahead, and risk avoidance.” Consequently, the Court insisted that a sentencer must consider mitigating factors in juvenile cases such as the stage in life that the teenager is at. This means, taking into consideration that adolescence is: (1) “a time of immaturity, irresponsibility, ‘impetuousness[,] and recklessness’”; (2) a moment in life when a person may get caught up in the claws of peer pressure, and (3) a time of mental and emotional development, which could lead to psychological damage.

CONCLUSION

Neurobiological research through M.R.I. has proved that teenagers’ brains and the way they function when making decisions or solving problems, are different than adults. Depending on the stage of the brains development, not the age, adolescents are prone to act on impulse and rewards, and will not measure right or wrong behavior (even though they recognize what is right and what is wrong). While brain scans do show differences between adult and teen brains, courts should decide whether or not that matters in the courtroom. Even if courtrooms decide not to engage in neuroimaging science, there is enough research to prove and focus on the importance of adolescent development. So, should the justice system punish a teenager who commits a serious crime differently from an adult that commits the same crime? As this article has explained, the answer is Yes. I am not suggesting that society should punish a teenager differently than an adult because teenagers need to be excused from total criminal responsibility. I am not arguing that at all. What I am suggesting is that research has shown that kids will mature; therefore, a kid that commits a crime is likely to reform. Teenagers, when up for sentencing, should be considered for rehabilitation. This gives them an opportunity to reform and phase out their criminal behavior; it gives them hope and prevents cruel punishments related to retribution.

It is time to re-evaluate the policies regarding young offenders, and advocate for policies that protect them from harsh punishments by assessing each adolescent’s maturity in order to determine a just punishment. After all, teenagers are treated as minors for many things, such as getting married, drinking, going to the casino, needing a parent or caretaker to go to the doctor; the justice system needs to be in sync with the times. Since it is not a viable idea to create a court to attend juvenile cases ranging from fifteen to nineteen years of age, what I am suggesting is to consider the offender’s age and maturity to mitigate the punishment. The United States Supreme Court has acknowledged several differences in brain development between youth and adult minds, and thus, has established mitigating factors to consider in juvenile cases. Professionals in the legal field and court systems need to educate themselves about these differences in brain development, how teenagers react to the world around them, and apply this knowledge when sentencing a juvenile felon.

The Impact of Adolescent Brain Development on Criminal Justice

The intersection of adolescent brain development and legal culpability presents a complex challenge within the legal community. While societal restrictions acknowledge the developmental differences between adolescents and adults in various domains (e.g., voting, military service), the criminal justice system grapples with determining appropriate accountability for minors who engage in criminal behavior. Recent neuroscientific discoveries highlighting the ongoing development of the adolescent brain into the early twenties underscore the ethical complexities of holding teenagers to the same legal standards as adults. This article examines the developmental trajectory of the adolescent brain, exploring its influence on decision-making and propensity for risk-taking, ultimately culminating in an analysis of how these neurobiological insights have shaped landmark United States Supreme Court decisions concerning juvenile offenders.

I. The Adolescent Brain: A Work in Progress

Understanding the unique characteristics of the adolescent brain is crucial for appreciating the challenges teenagers face in navigating complex social and emotional situations.

A. The Adolescent Brain: A Balancing Act

The period of adolescence, spanning roughly from ages eleven to twenty-four, represents a period of profound neural transformation. This dynamic process, characterized by significant structural and functional changes within the brain, underpins the behavioral and cognitive shifts observed during these formative years. Often described metaphorically as "a car with a good accelerator but a weak brake," the adolescent brain exhibits a heightened sensitivity to rewards and novelty, coupled with an underdeveloped capacity for impulse control and long-term planning. This neurobiological imbalance contributes to the increased proclivity for risk-taking and emotionally driven decision-making observed in adolescence.

B. Brain Development: A Closer Look

Advances in neuroimaging techniques, particularly Magnetic Resonance Imaging (MRI), have provided unprecedented insights into the structural and functional maturation of the adolescent brain.

i. Structural Brain Development

While the human brain attains approximately ninety percent of its adult size by age six, significant developmental processes continue throughout adolescence and into early adulthood. A key process during this period is myelination, involving the formation of a fatty sheath around nerve fibers (axons) that enhances the speed and efficiency of neural communication. Myelination progresses in a posterior-to-anterior direction, with areas responsible for higher-order cognitive functions, such as planning and impulse control (prefrontal cortex), maturing last. This protracted developmental trajectory of the prefrontal cortex contributes to adolescents' heightened sensitivity to rewards, susceptibility to peer influence, and difficulty with impulse control.

ii. Brain Development and Adolescent Behavior

The ongoing maturation of brain structures, particularly the prefrontal cortex, manifests in observable behavioral, cognitive, and emotional changes during adolescence. Research suggests that teenagers, compared to adults, demonstrate: (1) decreased capacity for self-regulation in emotionally charged contexts; (2) increased susceptibility to external influences, such as peer pressure; and (3) diminished ability to engage in future-oriented decision-making. These developmental vulnerabilities contribute to the increased likelihood of risk-taking and impulsive behaviors observed during adolescence.

II. Brain Development and Criminal Activity

The neurobiological underpinnings of adolescent behavior have significant implications for understanding the factors contributing to juvenile delinquency.

A. Peer Pressure: A Powerful Influence

Neuroimaging studies have revealed that the presence of peers can significantly amplify activity in brain regions associated with reward processing in adolescents. This heightened sensitivity to peer influence, coupled with an underdeveloped capacity for impulse control, increases the likelihood of teenagers engaging in risky or delinquent behavior when in the company of peers.

B. Parental Guidance: A Protective Factor

Parental support and guidance play a crucial role in shaping adolescent behavior and mitigating risk-taking tendencies. Research suggests that positive parenting practices, such as involvement, authoritative discipline, and emotional support, are associated with reduced risk of delinquency. Conversely, disengaged or neglectful parenting increases the likelihood of adolescents engaging in antisocial or criminal behavior.

III. Criminal Punishment & Juvenile Delinquency

The recognition of developmental differences between adolescent and adult offenders has sparked debate regarding appropriate punishment within the criminal justice system.

A. Retribution: A Question of Proportionality

The principle of retribution emphasizes punishment commensurate with the severity of the crime committed. However, the application of this principle to juvenile offenders raises concerns regarding proportionality, considering their diminished culpability due to developmental immaturity. Critics argue that harsh, retributive punishments may be ineffective in deterring future crime among adolescents, who are less likely to engage in cost-benefit analyses and more driven by immediate rewards.

B. Rehabilitation: Fostering Growth and Change

Rehabilitation focuses on addressing the underlying factors contributing to criminal behavior and providing opportunities for offenders to develop prosocial skills and reintegrate into society. Proponents of rehabilitation argue that this approach is particularly well-suited for juvenile offenders, who possess a greater capacity for change and growth due to their ongoing brain development.

C. Retribution vs. Rehabilitation in Juvenile Punishment

Balancing the principles of retribution and rehabilitation in the context of juvenile justice presents a significant challenge. While the adult criminal justice system often emphasizes punishment and deterrence, the juvenile justice system leans toward rehabilitation, recognizing the potential for growth and change in young offenders.

IV. Teenage Brain Development: Landmark Supreme Court Juvenile Cases

Several landmark Supreme Court cases have incorporated scientific understanding of adolescent brain development into decisions regarding appropriate sentencing for juvenile offenders.

A. Roper v. Simmons

In Roper v. Simmons (2005), the Supreme Court ruled that the death penalty for juveniles violated the Eighth Amendment's prohibition against cruel and unusual punishment. The Court cited developmental differences between adolescents and adults, highlighting adolescents' diminished culpability due to immaturity, susceptibility to peer influence, and greater capacity for rehabilitation.

B. Graham v. Florida

In Graham v. Florida (2010), the Supreme Court held that life sentences without the possibility of parole for juveniles who did not commit homicide constituted cruel and unusual punishment. The Court reiterated the developmental arguments from Roper, emphasizing the ongoing maturation of the adolescent brain and the potential for rehabilitation.

C. Miller v. Alabama

In Miller v. Alabama (2012), the Supreme Court ruled that mandatory life sentences without parole for juveniles, even in cases involving homicide, were unconstitutional. The Court reaffirmed the relevance of developmental neuroscience, stating that judges must consider the mitigating factors of youth when sentencing juvenile offenders.

Conclusion

Advances in neuroscience have provided compelling evidence of the distinct characteristics of the adolescent brain, highlighting the importance of considering developmental maturity in legal contexts. While teenagers are capable of understanding the difference between right and wrong, their developing brains render them more susceptible to impulsive behavior, peer influence, and emotionally driven decision-making. This understanding has prompted a shift toward a more rehabilitative approach in juvenile justice, recognizing the potential for growth and change in young offenders. As neuroscience continues to illuminate the complexities of the adolescent brain, it is imperative that the legal system adapts its approach to juvenile justice, ensuring fair and developmentally appropriate responses to youthful misconduct.

Teenage Brains and Criminal Justice: A Look at Why Age Matters

Navigating the line between childhood and adulthood is tricky, especially for the legal system. While teens can't vote, drink, or join the military, they might face adult consequences for serious crimes. This is concerning because scientific research now shows that a teenager's brain doesn't fully mature until their early twenties. This means adolescent brains operate differently than adult brains, often leading to impulsive actions and poor decisions. So, how should the law respond to teenage crime? This article explores the development of the adolescent brain, its impact on decision-making, and how these findings have influenced recent U.S. Supreme Court decisions.

I. The Adolescent Brain: A Work in Progress

Understanding the unique characteristics of the teenage brain is crucial for understanding their actions.

A. A Tale of Two Systems

The teenage brain is constantly changing, marked by significant growth and development. This period, known as adolescence, typically spans from ages eleven to twenty-four. It's a time of intense emotional fluctuations and evolving cognitive abilities. Imagine a car with a powerful engine but weak brakes – that's the adolescent brain, according to Professor Laurence Steinberg. Teens have strong impulses but lack the mature self-control to always rein them in.

Experts often describe the adolescent brain as having two competing systems. One is driven by the thrill of new experiences and the desire for peer approval, leading to risky behavior. The other, still under construction, is responsible for analyzing risks and making responsible decisions. This internal tug-of-war explains why teens sometimes make rash choices, even when they know better.

B. Wiring and Rewiring: Inside Brain Development

Neuroscience, particularly brain imaging techniques like MRI, has provided valuable insights into the adolescent brain. While the brain reaches 90% of its adult size by age six, the teenage years are crucial for its intricate wiring.

i. Structural Development

During adolescence, the brain undergoes a process called myelination, where axons (nerve fibers) become insulated with a fatty substance called myelin. This insulation speeds up the transmission of information, enhancing learning and cognitive abilities. Simultaneously, unused connections are pruned away, making the brain more efficient.

Importantly, this development starts from the back of the brain and moves forward, with the prefrontal cortex, responsible for planning, decision-making, and impulse control, maturing last. This explains why teens often struggle with these skills – their brains are literally still under construction!

ii. Impact on Daily Life

This ongoing brain development manifests in the behavioral, cognitive, and emotional changes characteristic of the teenage years. Teens might struggle with emotional regulation, be more susceptible to peer pressure, and have difficulty considering long-term consequences. They are wired to seek immediate rewards, even if it means taking risks.

II. From Brain Development to Criminal Activity

The link between the developing brain and delinquent behavior is a complex one.

While capable of rational thought, teens are more likely to make impulsive, emotion-driven decisions in stressful situations, especially when surrounded by peers. This is because their brains haven't fully developed the capacity to weigh risks and consequences effectively.

Several factors, alongside brain development, contribute to teenage delinquency:

A. The Power of Peers

Teenagers are highly sensitive to peer influence. Studies using MRI have shown that the presence of peers activates the reward centers of the brain in adolescents, making them more likely to engage in risky behavior to gain acceptance and approval.

This desire for peer approval can have dangerous consequences, particularly when it comes to violence. Research suggests that while teens are less likely to resort to violence when alone, the presence of peers can increase aggression and escalate conflicts.

B. The Importance of Parental Guidance

Parental support and guidance play a crucial role in navigating the challenges of adolescence. A stable and supportive family environment can provide teens with the structure and emotional support they need to develop healthy coping mechanisms and make positive choices.

Conversely, research indicates a strong correlation between negative parenting practices, such as neglect or harsh discipline, and increased rates of delinquency. Teens lacking a supportive home environment are more susceptible to negative peer influence and are at a higher risk of engaging in risky behaviors.

III. Juvenile Justice: Finding the Right Balance

The question of how to appropriately punish teenage offenders is a subject of ongoing debate. Should they face the same consequences as adults, or do their developing brains warrant a different approach?

While the principle of proportionality suggests that punishment should fit the crime, the unique characteristics of the adolescent brain complicate this equation. Teenagers are driven by different motivations than adults, and their capacity for change should be considered.

A. Retribution: Is It Enough?

Retribution focuses on punishing offenders based on the severity of their actions, aiming to deter future crime. However, this approach might be less effective for adolescents, who are less likely to be deterred by the threat of punishment, particularly when focused on immediate rewards.

B. Rehabilitation: A Chance to Change

Rehabilitation, on the other hand, emphasizes helping offenders reform and reintegrate into society. This approach aligns with the understanding that adolescent brains are still developing and therefore more malleable. Providing opportunities for education, therapy, and vocational training can equip young offenders with the skills and support they need to turn their lives around.

C. Prioritizing Rehabilitation in Juvenile Justice

Given the significant differences between adolescent and adult brains, many experts argue that the juvenile justice system should prioritize rehabilitation over retribution. Harsh punishments might not effectively deter future crime and could hinder a young person's chance at reform.

Investing in programs that address the underlying factors contributing to delinquency, such as substance abuse, trauma, or lack of educational opportunities, can have a more significant impact on reducing recidivism and promoting positive social outcomes.

IV. Supreme Court Cases: Recognizing Adolescent Differences

The evolving understanding of the adolescent brain has reached the highest court in the land, influencing key decisions related to juvenile sentencing.

A. Roper v. Simmons: Drawing a Line on Death Penalty

In Roper v. Simmons (2005), the Supreme Court abolished the death penalty for individuals who committed crimes under the age of 18. The Court recognized the inherent differences between adolescents and adults, citing their immaturity, susceptibility to peer pressure, and greater capacity for change as mitigating factors.

B. Graham v. Florida: Life Without Parole Reconsidered

Similarly, in Graham v. Florida (2010), the Court ruled that life sentences without the possibility of parole were unconstitutional for juveniles convicted of crimes other than homicide. This decision emphasized the ongoing development of the adolescent brain and the importance of providing opportunities for rehabilitation.

C. Miller v. Alabama: Mandatory Sentences Deemed Unjust

Continuing this trend, Miller v. Alabama (2012) extended the ban on mandatory life-without-parole sentences to all juvenile offenders, even in cases involving homicide. The Court reiterated the unique characteristics of adolescence and stressed the need for individualized sentencing that considers a young person's potential for rehabilitation.

Conclusion: A Call for Reform

The growing body of scientific evidence regarding adolescent brain development has significant implications for the criminal justice system. Treating teenagers like miniature adults ignores the fundamental differences in their cognitive and emotional development, potentially leading to unjust and ineffective outcomes.

While accountability is crucial, it's essential to balance punishment with opportunities for rehabilitation and growth. By acknowledging the unique vulnerabilities and potential of the adolescent brain, the justice system can play a more constructive role in guiding young offenders towards a brighter future.

Teen Brains and Tough Choices: Why the Legal System Needs to Catch Up

Ever wonder why teenagers sometimes make decisions that seem illogical? It turns out, there's a scientific reason! This article dives into how the teenage brain develops and why it matters when it comes to making big decisions, especially ones that involve breaking the law.

I. Work in Progress: Understanding the Teenage Brain

We've all heard the phrase "teenager" and instantly thought of crazy hormones and impulsive actions. While there's some truth to that, it all comes down to what's happening inside the teenage brain.

A. A Brain Unlike Any Other

Think of the teenage brain like a car with a supercharged engine but weak brakes – tons of power and impulse, but not enough control. From ages 11 to 24, the brain is going through major renovations, especially in the front part responsible for decision-making, planning, and self-control. This means teens are more likely to act on gut feelings rather than thinking things through, especially in the heat of the moment.

This doesn't mean teens can't tell right from wrong! It's just that their brains are wired to seek thrills and social rewards, sometimes overriding that inner voice of reason. Add in the pressure to fit in with friends, and you've got a recipe for risky choices.

B. Building a Better Brain

Thanks to cool technology like MRI scans, scientists can now literally see the brain rewiring itself during the teenage years.

1. Building Blocks of the Brain

Even though your brain is almost adult-sized by age 6, the real work is just beginning. Imagine your brain as a complex network of roads. During adolescence, those roads are being paved and upgraded (myelination), allowing thoughts to travel faster and smoother. At the same time, new connections are sprouting (dendrites and synapses), creating more complex pathways. It's like going from backroads to a superhighway! This process, however, takes time, and the last area to fully mature is the prefrontal cortex – the boss of the brain.

2. From Brain Changes to Real-Life Choices

This brain rewiring has a big impact on how teenagers act, think, and feel. It explains why teens often struggle with controlling impulses, thinking long-term, and resisting peer pressure. They're also more sensitive to emotions and easily influenced by feelings of reward, which can lead to seeking out exciting, even if risky, experiences. The good news? As the brain matures, so does the ability to make smarter and more rational decisions.

II. When Teen Brains and Crime Collide

Because the teenage brain is still under construction, it's no surprise that some teens end up making choices that get them in trouble with the law. They might not fully grasp the consequences of their actions or think they're invincible.

A. The Power of the Pack

Ever notice how being around friends can make you do things you wouldn't normally do? That's because the teenage brain is super sensitive to social rewards. MRI studies show that the reward centers of teen brains light up like fireworks when they're with friends, especially when taking risks. This intense desire for peer approval can lead teens to make bad choices, even if they know better deep down.

B. Parents as Brain Builders

This is where parents and caregivers come in! While it's tempting to shield teens from all of life's challenges, what they really need is guidance and support to navigate this tricky time. Studies show that teens raised in homes with involved and caring parents are less likely to engage in risky behavior. Parents can help by setting clear expectations, encouraging healthy activities, and being a source of support when things get tough.

III. Finding the Right Balance: Punishing Teen Crime

The justice system faces a tough question: how do you hold teenagers accountable for their actions while also acknowledging that their brains aren't fully developed?

A. An Eye for an Eye: Does Retribution Really Work?

Some people believe in harsh punishments to fit the crime. The idea is that the punishment should be equal to the harm caused, regardless of age. While this might sound fair, it doesn't always work with teenagers. Because their brains are wired for immediate rewards, the threat of future consequences isn't always effective in deterring crime.

B. A Second Chance: The Power of Rehabilitation

Rehabilitation, on the other hand, focuses on helping young offenders change their behavior and become productive members of society. Since teen brains are still moldable, they're more likely to respond to programs that teach them new skills, address underlying issues, and provide support. This approach not only gives teens a second chance but also reduces the likelihood of them committing crimes in the future.

C. Finding a Better Way: Rethinking Juvenile Justice

The current justice system often seems stuck between punishing teens like adults and recognizing their unique needs. Instead of automatically trying and sentencing teens in the adult system, courts should consider their age, maturity, and potential for rehabilitation. After all, shouldn't the goal be to guide young people towards a brighter future instead of locking them up and throwing away the key?

IV. Landmark Cases: The Supreme Court Speaks Up

In recent years, even the highest court in the land – the Supreme Court – has started to recognize the science behind the teenage brain. In cases like Roper v. Simmons, Graham v. Florida, and Miller v. Alabama, the Court ruled that harsh punishments like the death penalty and life without parole are unconstitutional for juveniles. Why? Because these punishments don't take into account the unique characteristics of the adolescent brain, including its capacity for change.

Conclusion: It's Time to Bridge the Gap

The science is clear: teenage brains are different from adult brains. This knowledge should be reflected in the way we address juvenile crime. Instead of simply punishing teenagers, we need to invest in programs and policies that support their development and provide opportunities for rehabilitation. By understanding the adolescent brain, we can create a justice system that is both fair and effective in promoting long-term positive change.

I. Building a Brain: How Come Teenagers Act So Impulsive?

Imagine the brain is like a fancy car. A teenager's brain has a super powerful engine (that's like the part of the brain that wants to do exciting things), but the brakes aren't very strong yet (that's the part that helps you stop and think before you act). This means that teenagers might have trouble controlling their impulses – those sudden urges to do something without thinking!

Inside their brains, teenagers are going through a lot of changes. They are trying to figure out who they are, what they like, and how they fit in with the world. This can be exciting, but it can also be confusing and lead to risky decisions.

A. The Growing Brain

The brain is made of billions of tiny parts that talk to each other. During the teenage years, the connections between these parts are still getting stronger and faster. One of the last parts of the brain to finish growing is called the prefrontal cortex. This part helps us make good decisions, plan for the future, and control our emotions. Since it's still under construction in teenagers, they might make choices based on how they feel right now, rather than thinking about what might happen later.

B. How Brains Get Wired

Scientists can use special machines called MRI scanners to watch how brains grow. They can see how different parts of the brain connect and talk to each other. This helps them understand why teenagers act differently than adults. For example, the part of the brain that makes us feel good when we get a reward is very active in teenagers. This means they might be more likely to take risks if they think they'll get something good out of it, like praise from their friends.

II. Why Do Some Teenagers Break the Law?

We know that teenage brains are still developing, and this can make them more likely to take risks. But there are other important factors that can lead to teenagers getting into trouble.

A. Powerful Friends

Peer pressure is a common feeling, especially for teenagers. Their brains are wired to care a lot about what their friends think. This can be a good thing, but it can also lead them to do risky or even dangerous things if they think it will impress their peers.

B. Guidance from Grown-Ups

Just like a car needs a driver, a developing brain needs guidance from parents and other caring adults. Teenagers need clear rules and boundaries, but they also need support and understanding. When adults are involved in their lives and provide a listening ear, teenagers are less likely to make choices that get them into trouble.

III. Second Chances: What Happens When Teenagers Break the Law?

When someone breaks the law, there are consequences. But should teenagers be punished the same way as adults? Some people believe in retribution – that the punishment should fit the crime, no matter who committed it. Others believe in rehabilitation – that the focus should be on helping the person change their behavior so they don't break the law again.

A. Punishment or Change?

Remember that teenagers' brains are still developing, which means they have a greater capacity for change. This is why many experts believe that rehabilitation is a better approach than simply punishing teenagers who break the law. Instead of sending them to adult prison, where they might learn bad habits from hardened criminals, programs that focus on education, counseling, and job training can give teenagers the tools they need to turn their lives around.

B. What About Serious Crimes?

Even when teenagers commit serious crimes, it's important to remember that they are still developing and have a greater potential for rehabilitation than adults. Sentences like life in prison without the possibility of parole take away all hope for the future and don't give teenagers a chance to grow and change.

IV. The Highest Court in the Land Weighs In

The Supreme Court is the most important court in the United States. It has heard several cases involving teenagers who committed serious crimes and has made some important decisions based on what scientists have discovered about the teenage brain. The Court has said that teenagers are less culpable than adults – meaning they are not as responsible for their actions because their brains are not fully developed. The Court has also said that teenagers should have a chance to show that they can change and should not be given punishments that are too harsh or don't allow for rehabilitation.

A. Important Cases

In cases like Roper v. Simmons, Graham v. Florida, and Miller v. Alabama, the Supreme Court has said that it is unconstitutional – or against the law – to give teenagers the death penalty or life in prison without the possibility of parole. The Court has recognized that teenagers' brains are different and that they deserve a chance to turn their lives around.

CONCLUSION

Teenage brains need time, care, and guidance to reach their full potential. Instead of punishing teenagers as if they were mini-adults, we should focus on understanding how their developing brains work and create a justice system that offers them a chance to learn from their mistakes and become responsible members of society.
