Teens who help strangers have more confidence: Get your kids involved in service to strangers in this season of giving, researchers suggest -- ScienceDailyIn the study, researchers looked at 681 adolescents, 11-14 years old, in two U.S. cities. They tracked them for four different time points, starting in 2008 through 2011. The participants responded to 10 statements such as "I feel useless at times" or "I am satisfied with myself" to assess self-esteem. Prosocial behavior was measured by self-reports, looking at various aspects of kindness and generosity, such as "I help people I don't know, even if it's not easy for me" or "I go out of my way to cheer up my friends" or "I really enjoy doing small favors for my family." "A unique feature of this study is that it explores helping behaviors toward multiple different targets," Padilla-Walker said. "Not all helping is created equal, and we're finding that prosocial behavior toward strangers is protective in a variety of ways that is unique from other types of helping. Another important finding is that the link between prosocial behavior and self-esteem is over a one-year time period and present across all three age lags in our study. Though not an overly large effect, this suggests a stable link between helping and feeling better about oneself across the early adolescent years."
College depressionIn 2013 the American College Health Association surveyed close to 100,000 college students from 153 different campuses about their health. When asked about their experiences, at some point over the past 12 months: 84.3 percent felt overwhelmed by all they had to do 60.5 percent felt very sad 57.0 percent felt very lonely 51.3 percent felt overwhelming anxiety 8.0 percent seriously considered suicide The 153 schools surveyed included campuses in all 50 states, small liberal arts colleges and large research universities, religious institutions and nonreligious, from the small to medium-sized to the very the large.
An unfortunate incident, a teachable moment | John PalfreyWith the benefit of a few days of reflection, the primary lesson I take away from these events is one of humility. Personally, I realize the limits of my persuasive power […]. A few weeks ago, I stood before all 328 graduating students in Cochran Chapel and told them unequivocally not to host or to attend such a party. On large screens in the chapel, as a cautionary tale, I put up a recent newspaper article about a peer school at which a large number of former students were arrested at a graduation party in northern New England. We sent a clear letter to students and families about graduation week, as we do every year; we held follow-up meetings with students and parents to forestall these events. As we now know, for some students, these efforts did not prevent such an event from taking place.
Risking MRSA for acne treatment“The pit in my stomach grows a little bigger every time I prescribe oral antibiotics to healthy, athletic teenagers for their acne knowing I am increasing their risk of contracting MRSA from the locker room, classroom or anywhere in the community,” dermatologist Sandra Johnson of Fort Smith, Ark., wrote in a February letter to the professional newsletter Dermatology Times.
Meanwhile, in times of doubt, take inspiration in one last distinction of the teen brain—a final key to both its clumsiness and its remarkable adaptability. This is the prolonged plasticity of those late-developing frontal areas as they slowly mature. As noted earlier, these areas are the last to lay down the fatty myelin insulation—the brain's white matter—that speeds transmission. And at first glance this seems like bad news: If we need these areas for the complex task of entering the world, why aren't they running at full speed when the challenges are most daunting? The answer is that speed comes at the price of flexibility. While a myelin coating greatly accelerates an axon's bandwidth, it also inhibits the growth of new branches from the axon. According to Douglas Fields, an NIH neuroscientist who has spent years studying myelin, "This makes the period when a brain area lays down myelin a sort of crucial period of learning—the wiring is getting upgraded, but once that's done, it's harder to change."
Yet teens gravitate toward peers for another, more powerful reason: to invest in the future rather than the past. We enter a world made by our parents. But we will live most of our lives, and prosper (or not) in a world run and remade by our peers. Knowing, understanding, and building relationships with them bears critically on success. Socially savvy rats or monkeys, for instance, generally get the best nesting areas or territories, the most food and water, more allies, and more sex with better and fitter mates. And no species is more intricately and deeply social than humans are.
Researchers such as Steinberg and Casey believe this risk-friendly weighing of cost versus reward has been selected for because, over the course of human evolution, the willingness to take risks during this period of life has granted an adaptive edge. Succeeding often requires moving out of the home and into less secure situations. "The more you seek novelty and take risks," says Baird, "the better you do." This responsiveness to reward thus works like the desire for new sensation: It gets you out of the house and into new turf.
our brains undergo a massive reorganization between our 12th and 25th years. The brain doesn't actually grow very much during this period. It has already reached 90 percent of its full size by the time a person is six, and a thickening skull accounts for most head growth afterward. But as we move through adolescence, the brain undergoes extensive remodeling, resembling a network and wiring upgrade. For starters, the brain's axons—the long nerve fibers that neurons use to send signals to other neurons—become gradually more insulated with a fatty substance called myelin (the brain's white matter), eventually boosting the axons' transmission speed up to a hundred times. Meanwhile, dendrites, the branchlike extensions that neurons use to receive signals from nearby axons, grow twiggier, and the most heavily used synapses—the little chemical junctures across which axons and dendrites pass notes—grow richer and stronger. At the same time, synapses that see little use begin to wither. This synaptic pruning, as it is called, causes the brain's cortex—the outer layer of gray matter where we do much of our conscious and complicated thinking—to become thinner but more efficient. Taken together, these changes make the entire brain a much faster and more sophisticated organ.
Through the ages, most answers have cited dark forces that uniquely affect the teen. Aristotle concluded more than 2,300 years ago that "the young are heated by Nature as drunken men by wine." A shepherd in William Shakespeare's The Winter's Tale wishes "there were no age between ten and three-and-twenty, or that youth would sleep out the rest; for there is nothing in the between but getting wenches with child, wronging the ancientry, stealing, fighting." His lament colors most modern scientific inquiries as well. G. Stanley Hall, who formalized adolescent studies with his 1904 Adolescence: Its Psychology and Its Relations to Physiology, Anthropology, Sociology, Sex, Crime, Religion and Education, believed this period of "storm and stress" replicated earlier, less civilized stages of human development. Freud saw adolescence as an expression of torturous psychosexual conflict; Erik Erikson, as the most tumultuous of life's several identity crises. Adolescence: always a problem.
