Review by Powerpoint

Through the endless pursuit of research, some of the best stories are the result of approaching a topic through multiple expertise. For instance, there was a study our of Pittsburgh that attempted to tackle the understanding of why teenagers seem to be "impulsive." This has an impact on society since EVERYONE has experienced this impulsiveness, and it would be beneficial to understand this moment in life.

I will let you first take a gander at the power point real quick, since I intended you to do so. Don't feel guilty and just do it.

O.K., now that you have looked over these few slides, I just want to expound upon a little bit. The value of this study was that it took an apparent observation -teenagers seem to act more recklessly than adults- and then explored whether there was a biological explanation for this observation. An experiment using mice resulted in significant results showing that indeed there must be some biological explanation, and that under stressful conditions further exacerbates this impulsiveness.

The ironic thing is that in the end the most likely explanation of this impulsiveness is that it is a maturity thing...but of the brain. It is likely that there are some changes that the brain undergoes in its development that makes people and animals to be more cautious and less impulsive. Now the next step is to verify this hypothesis with some continual studies, and then we will truly know why teenagers are impulsive.
