Every fall, like clockwork, Linda Krentz of Beaverton, Oregon, felt her brain go on strike. "I just couldn't get going in the morning," she says. "I'd get depressed and gain 10 pounds every winter and lose them again in the spring." Then she read about seasonal affective disorder, a form of depression that occurs in fall and winter, and she saw the light literally. Every morning now she turns on a specially constructed light box for half an hour and sits in front of it to trick her brain into thinking it's still enjoying those long summer days. It seems to work. Krentz is not alone. Scientists estimate that 10 million Americans suffer from seasonal depression and 25 million more develop milder versions. But there's never been definitive proof that treatment with very bright lights makes a difference. After all, it's hard to do a double-blind test when the subjects can see for themselves whether or not the light is on. That's why nobody has ever separated the real effects of light therapy from placebo effects. Until now, in three separate studies published last month, researchers report not only that light therapy works better than a placebo but that treatment is usually more effective in the early morning than in the evening. In two of the groups, the placebo problem was resolved by telling patients they were comparing light boxes to a new anti-depressant device that gives off negatively charged ions . The third used the timing of light therapy as the control. Why does light therapy work? No one really knows. "Our research suggests it has something to do with shifting the body's internal clock," says psychiatrist Dr. Lewey. The body is programmed to start the day with sunrise, he explains, and this gets later as the days get shorter. But why such subtle shifts make some people depressed and not others is a mystery. That hasn't stopped thousands of winter depressives from trying to heal themselves. Light boxes for that purpose are available without a doctor's prescription. That bothers psychologist Michael... What is the CURRENT view concerning the treatment of seasonal depression with bright lights? A) Its effect remains to be seen. B) It serves as a kind of placebo. C) It proves to be an effective therapy. D) It hardly produces any effects.

Students who date in middle school have significantly worse study skills. They are four times more likely to drop out of school and report twice as much alcohol and tobacco use as their single classmates, according to new research from the University of Georgia. "Romantic relationships are a trademark of adolescence, but very few studies have examined how adolescents differ in the development of these relationships," said Pamela Orpinas, study author and professor in the College of Public Health and head of the Department of Health Promotion and Behavior.[: _ Z _ X _ X _ K] Orpinas followed a group of 624 students over a seven-year period from 6th to 12th grade. Each year, the group of students completed a survey indicating whether they had dated and reported the frequency of different behaviors, including the use of drugs and alcohol. Their teachers completed questionnaires about the students' academic efforts. He found some students never or hardly ever reported dating from middle to high school, and these students had consistently the best study skills according to their teachers. Other students dated infrequently in middle school but increased the frequency of dating in high school. "At all points in time, teachers rated the students who reported the lowest frequency of dating as having the best study skills and the students with the highest dating as having the worst study skills," according to the journal article. Study skills refer to behaviors that lead to academic success such as doing work for extra credit being well organized, finishing homework, working hard and reading assigned chapters. "Dating a classmate may have the same emotional complications of dating a co-worker," Orpinas said, "When the couple break up, they have to continue to see each other in class and perhaps witness the ex-partner dating someone else. It is reasonable to think this could be linked to depression and divert attention from studying." "Dating should not be considered a ceremony of growth in middle school," Orpinas concluded. Orpinas' attitude towards dating in middle school is _ A) supportive B) positive C) negative D) indifferent
