In this entry, Carl Zimmer clearly states that fast driving, drugs, and unsefe sex: The risk-loving behavir of teenagers may result from a neurological gap in the development of the brain.
Study shows that this case applies to many situations. For example, scientists ran a study on a group of rats of varying ages, allowing the animals to drink as much sweetened condensed milk as they wanted. The rats had to press the lever dozens of times before they were rewarded with a single sip, and each successive sip required two more presses than the previous one. They found that pubescent rats would press the lever much more often than rats of any other age, putting in more work for the calories given their size. In other words they valued the milk more. The affects of adolescence on rats parallels the affects adolescence has on humans. Whether rodent or human, adolescene makes us add more value not only to sweet drinks, but to all sorts or rewards.
Another study shown in this write up similar to the previous one would be the study they did on humans varying in ages. It was an experiment where scientists arranged four decks in various ways. The scientists had stacked the decks. Two of the decks had more losing cards than winning ones, and the reverse was true for the other two decks. Scientists tracked the strategies of 901 volunteers ranging in age from 10 to 30 years old and compared the teenagers with the other age groups, Adolescents tended to play the winning decks more often than adults or preteens. In other words, they wewe unusually sensitive to the reward of winning money but the same as others when it came to a risk in losing it. Adolescents had a unique way in placing value on things. It is remarkable that the affects are similar in both cases between the humans and the rats. I guess we are not too far off from the animal kingdom after all...
The reading also goes into detail about teens and the affects of a neurological gap. "The trubble with teens is that they fall into a neurological gap." Until it catches up, teenagers are stuck with strong responces to rewards without much of a compensating responce to the associated risks. The reward system of the teenage brain may make adolescents more willing to face the risks that come with this advancing new stage of life. This may act as a "cussion" supressing the difficulty and advancement into adulthood and becoming more independent. The problem is that with modern dangers such as illegal drugs and fast cars, the human risks have increased. Evolution does not operate quickly enough to have reacted to such factors.
To conclude, this particular reading interested me the most mainly because it deals with the study of people in our own age group. I find it interesting to learn more about ones self and how your body/nervous system works and cooperates with eachother. The affects of adolescence is an interesting topic, one worthy of discussion!
