Surprising Results In Teen Study: Adolescent Risky Behavior May Signal Mature Brain
A new study using brain imaging to study teen behavior indicates that adolescents who engage in dangerous activities have frontal white matter tracts that are more adult in form than their more conservative peers.
The brain goes through a course of maturation during adolescence and does not reach its adult form until the mid-twenties. A long-standing theory of adolescent behavior has assumed that this delayed brain maturation is the cause of impulsive and dangerous decisions in adolescence. The new study, using a new form of brain imaging, calls into question this theory.
In order to better understand the relationship between high risk-taking and the brain's development, Emory University and Emory School of Medicine neuroscientists used a form of magnetic resonance imaging (MRI) called diffusion tensor imaging (DTI) to measure structural changes in white matter in the brain. The study's findings are published in the Aug. 26, 2009 PLoS One.
"In the past, studies have focused on the pattern of gray matter density from childhood to early adulthood, says Gregory Berns, MD, PhD, principal investigator and professor of Psychiatry and Neuroeconomics at Emory University and director of the Center for Neuropolicy. "With new technology, we were able to develop the first study looking at how development of white matter relates to activities in the real world."
Gray matter is the part of the brain made up of neurons, while white matter connects neurons to each other. As the brain matures, white matter becomes denser and more organized. Gray matter and white matter follow different trajectories. Both are important for understanding brain function.
The study enrolled 91adolescents ages 12 through 18 over a three-year period. Levels of engagement in dangerous behaviors were measured by a survey that included questions about the teens' thrill seeking behaviors, reckless behaviors, rebellious behaviors and antisocial behaviors. DTI was used to measure corresponding structural changes in white matter.
"We were surprised to discover that risk-taking was associated with more highly-developed white matter – a more mature brain," says Berns. "We were also surprised to learn that except for slightly higher scores in risk-taking, there was no significant difference in the maturity of the white matter between males and females."
Berns suggests that doing adult-like activities requires sophisticated skills.
"Society is a lot different now than it was 100 years ago when teens were expected to go to work and raise a family," says Berns. "Now, adolescents aren't expected to act like adults until they are in their twenties, when they have finished their education and found a career.
"You could make the case that in this country, biological capacity shows up long before the wisdom that comes with time is fully developed," notes Berns.
Berns says more studies need to be done to determine if early brain development predisposes someone to engage in risky behaviors, or if the risky behavior drives the maturation of the brain.
The CDC reports that, 27,000 people between the ages of 10 and 24 die from bad decisions in the United States per year. Additionally, it has been shown that the period of mid-adolescence (ages 15 through 19) is the time when teens are more likely to begin high-risk behaviors such as drinking, abusing drugs or driving recklessly.
Other researchers who contributed to this study include, Sara Moore, BS, Department of Psychiatry and Behavioral Sciences at Emory University School of Medicine and C. Monica Capra, PhD, the Department of Economics and the Center for Neuropolicy, Emory University.
This study was funded by grants from the National Institute on Drug Abuse.

The Personal Fable of Adolescents
Understanding the Fantasy Construct Common to Youth
The Concept of the Personal Fable and Its Challenges
- All experiences are unique, nothing happens to anyone else like does to me.
- My experiences are special, no one can understand what I go through.
- My feelings are unique, no one has ever felt as I do.
- Nothing bad will happen to me, accidents only happen to others.

Adolescent Peer Pressure - Wanting to Fit In
By Yvonne Clark
Peer pressure is not isolated to one age group, everyone needs to belong or feel connected to his or her own age group. Kids and adults are partnered to peer pressure. Teens like adults are influenced by their peer group. This is normal behavior and is modeled for teenagers by the adults around them. As adults, we are familiar with the expression "keeping up with the Jones'," a sense of wanting to fit in. Adults conform to the social standards set by their peers and teenagers are very carefully watching the adults that influence his or her life.
Teen peer pressure -is more than just a phase that young people go through. Whether it leads to extreme hair and clothing, tattoos, or body piercing, peer pressure is a powerful reality and many adults do not realize its effects. It can be a negative force in the lives of children and adolescents, often resulting in their experimenting with tobacco, alcohol, and illegal drugs.
Teenagers want to be with people their own age. Children, especially during adolescence, begin to spend a lot more time with their friends, and less time with their family. This makes them more susceptible to the influences of their peers. It is important to remember that teenage friends can have a positive influence on a youth. During teenage years, young people are more accepting of their peers feelings and thoughts. Peers can and do act as positive role models.
Parents, teachers, and other adults should encourage teenagers to find friends that have similar interests and views as you a parent, educator, religious and community leader are trying to develop in the teen. The critical adult views including doing well in school, having respect for others, avoiding drug use, smoking, drinking and other risky behaviors.
During adolescence, young people put into practice risk-taking behaviors as they are trying to find their own identity and become more independent. This makes them very vulnerable to experimenting or becoming addicted to drugs and alcohol, sexual activity, and defiance of authority, especially if there is peer pressure to do so. Adolescents who use drugs are also more likely to become involved in gang activity, have low self-esteem, behavior problems, school performance problems, and depression.
Parents, teachers, religious and community leaders want to promote positive peer pressure among teens. Parents and other adults often believe that teenagers do not value their opinions. In reality, studies suggest that parents have tremendous influence over their children, especially teenagers. No matter the age of their children, parents, caregivers and other adult role models should never feel helpless about countering the negative effects of peer pressure.
Here are some suggestions what parents and other adults can do:
o Establish and maintain good communications
o Nurture strong self-esteem
o Avoid criticism that takes the form of ridicule or shame
o Monitor your teens activities
o Role-play peer pressure situations
o Talk openly and honestly about stealing, alcohol, illegal drugs, and sex
o Avoid attacking the teen's friends- criticizing a teenagers choice of friend can be perceived by a teen as a personal attack.
o Be an involved parent
o Ask questions and enjoy listening to teenagers as he or she talks
o Get teenagers involved in youth groups, community activities and peer monitoring programs
o Help the teen understand the difference between image (expressions of youth culture) and identity (who he or she is)
Peer pressure during childhood and adolescence equips young people to develop healthy friendships, self-identity, self-esteem, and self-reliance. It is healthy for everyone to talk about how they feel what they need, desire and want. Parents mistakenly assume that their teen does not want to talk to them, but it may just be that the teenager does not want to talk about his or her bad grades, their bad behavior and how much trouble they are in. Usually teenagers are more willing to talk about something they are interested in or something positive that is about them.
Develop a habit of talking with your teen everyday. Building a strong close open relationship with him or her while they are young will make it easier for your teen to discuss problems, concerns and other sensitive issues associated with school, relationships, and other life stressors.
Beyond Facebook: the Benefits of Deeper Friendships
Constantly connected via Facebook and Twitter, you may feel like you have a lot of friends. But will they be your go-to friends in a crisis?
Overwhelmed by home, family and work obligations, many people find it difficult to make and maintain deep friendships. Yet these connections are the kind that best support health and happiness.
When one of her high-school friends was laid off, Lauren Thormeier of Dublin, Ohio, took time out of her workday as a clinical therapist and left housework undone to listen to her friend air her worries and to brainstorm solutions. "You just say to yourself, the dishes can wait, the laundry can wait. Your friend needs you." In turn, Ms. Thormeier says, she knows she could call her friend "in the middle of the night" in a crisis.
Friendships of any kind can bear health benefits. The most satisfied, contented mothers are the ones who spend the most time each week connecting with friends, according to a survey of 2,000 mothers by CafeMom, a website for mothers. Social and emotional support is linked in numerous studies to better health and lower rates of disability, depression and anxiety.
Janet Schiavone, Nikki George, Joan Confoy and Donna Lee, left to right, have a group called 'Girl Talk.'
But the deepest friendships confer the greatest benefits. A sense of being loved, cared for and listened to fosters a sense of meaning and purpose and reduces stress-induced wear and tear on the body, lowering the heart rate, blood pressure and stress hormones, according to research published last month in the Journal of Health and Social Behavior. Supportive friendships also are linked in research to increased longevity and may actually change the way you experience stressful events, buffering the negative mental effects.
Friends have a measurable impact in reducing depression after life turning points, research shows. New parents who were more satisfied with their friendships reported lower rates of depression after childbirth, says a study of 137 couples published in 2002 in the Journal of Marriage and Family.
Such friendships seem to hold more health benefits for woman than men. Among men and women who had experienced emotional abuse or neglect in childhood, according to a study published last year in the journal Depression and Anxiety, women who had supportive friends faced a significantly better chance of fighting off depression in adulthood—but not men.
While the reasons aren't completely clear, other research shows men place less emphasis than women on the depth of their ties with friends and more emphasis on how often they see them or how long they have known them. Women, on the other hand, tend to have more intimate bonds with their friends, and they stress the emotional qualities of their relationships.
While the Girl Talk members have plenty of differences that might divide them—the women are both at-home and working mothers, Republicans and Democrats, and their religious backgrounds differ—"we're beyond labels," Ms. Schiavone says. "We're friends—and that has been our saving grace."

Counting your blessing: being thankful and grateful does help you feel NTV7
By Khor Gui Wei (Nathan)
Be grateful 感恩- The Honorable Zheng Yan, Founder of Charity Foundation Chi-tzu
Have you ever been throwing out your grievances to people around you about how boring your life is in Kampar? Weather is so hot la, parkings are so few la, lecture class, assignment exam SO MANY la (Tan, 2010). Arghh, you could not stand it.
But wait, have you ever tried to improve the situation?
Of course, you are not superman or wonderwoman. You can’t shot down the sun, build parking complex with one hand and topple down the management to overturn the system. But why don’t we start from simple thing, say yourself? Instead of trying hard to change the objective reality, I suggest we adjust our subjective inner state. Heard about Louis Armstrong before? Yes, he was the Jazz singer who sang “I feel good” whenever you switch your channel to NTV7. Here we will discuss about how to make yourself “feel good”.
If you ever had chance to go through those Holy Scriptures, you would find that most of the religions preach on one common theme- be grateful. Be it Christian, Islam or Buddhism. However, we are not going to discuss on religious basis. We shall see what researchers have found in their studies regarding gratitude, mostly done on adolescents.
Researchers discovered that people, who are grateful to things that happened around them, no matter big or small, tend to be more grateful, optimistic, satisfied with life condition and a decrease in negative affect (Froh, Yurkewicz, & Kashdan, 2009). Furthermore, one who is grateful tends to lend a helping hand to those in need. In other word, grateful people are more prosocial. Several researches also indicated grateful people tend to have better life appraisal and thus spend more time in exercising, resulting in better health (Emmons & McCullough, 2003). Besides than that, these people show higher levels of positive affect- proud, hopeful, inspired, forgiving, and excited (Froh, Yurkewicz, & Kashdan, 2009). Most importantly, grateful adolescents tend to report great satisfaction with their school experience (Froh, Sefick, & McCullough, 2008).
Perhaps after you read through the brief summary of the researches above, you would have doubted whether it could really be so powerful in improving your life, just by being grateful. So I shall say you could always try it yourself, no harm right? It won’t spend a single penny from your tight pocket, especially in this short semester.
If you would like to give it a try, here are few suggestions to end this sharing also :
1) Think back 5 things that you feel thankful for, big or small, everyday.
2) Say thank you to yourself, appreciating the efforts your SELF have put in. For instance, work hard in assignment, able to control your emotion and thus avoid interpersonal conflict.
3) Feel grateful to those who have helped you.
4) Feel grateful to what you have now ( opportunity of education, no famine, etc.)
5) And many many more ways waiting you to discover. = )
