The distracted teenage brain . Researchers have blamed those poor decisions on the immaturity of a teen. That is the part of the brain involved in making plans and decisions. But scientists now find the answer may be simpler: the allure of rewards. Rewards, even small ones, entice teens more than they do adults. And, perhaps surprisingly, teens tend to continue doing things they once found rewarding, even after the actual payoff is long gone. Both findings come from a new study by researchers at the University of Iowa in Iowa City. Psychologist Zachary Roper and his team worked with two groups of volunteers: 1. Each volunteer had to play a game of sorts. During a training phase, a computer displayed six circles, each a different color. The players had to find the red or green circle. These targets had either a horizontal or vertical line inside. The remaining circles had lines at other angles. When the participant found the correct target, they had to press one of two keys on a keyboard. One key would report they had found the vertical line. The other reported finding a horizontal line.

When a volunteer hit the right key, the screen flashed the amount of the reward they had earned. For some volunteers, green circles provided a large (1. For other volunteers, the amounts were reversed, with red circles worth more. All other colors had no reward. By the end of this training, volunteers had learned the value of each color. When the scientists asked the players about the value of red versus green circles, both teens and adults had no awareness that a circle. The scientists informed the volunteers they had a new target. Each had to report the orientation of the line inside a blue diamond. Again, groups of six symbols appeared on a computer screen. Only one was a diamond. The other five were still circles. In some trials, one of those circles was red or green. In other trials, there were no red or green circles. The recruits were told to answer as quickly as possible. And for this phase of the experiment, no additional money would be earned. The researchers now measured how long it took people to find the diamond and record their answers. When no red or green circles were among the onscreen options, both adults and teens responded quickly. But when a red or green circle showed up, both groups initially took a bit longer. Adults, though, quickly stopped paying attention to the colored circles. Their response times sped up. Teens reacted differently. They took longer to respond whenever a red or green circle showed up. Their response times never sped up. Their attention still was drawn to the previously valued circles . Clearly, the red and green circles were distracting teens from their objective. Roper. A psychologist at Johns Hopkins University in Baltimore, Md., he was not involved with the study. These data may help explain why teens engage in risky behavior, he says. Some behaviors, such as texting or using social media, trigger the brain. Once the teenage brain has linked a behavior to that reward, it continues to seek the reward again and again. Or why they respond to texts while driving. How can someone overcome their brain? Vaidya suggests physically removing distractions whenever possible. Shut down the phone when driving or disconnect from Wi- Fi while doing homework. When distractions are not readily available, it will be easier to focus attention on the things that matter most. Like arriving home safely. Located behind the forehead, it plays a role in making decisions and other complex mental activities, in emotions and in behaviors.
