HOFFMAN (6/23/14): A constellation of three popularity-seeking behaviors characterized pseudomaturity, Dr. Allen and his colleagues found. These young teenagers sought out friends who were physically attractive; their romances were more numerous, emotionally intense and sexually exploring than those of their peers; and they dabbled in minor delinquency — skipping school, sneaking into movies, vandalism.
As they turned 23, the study found that when compared to their socially slower-moving middle-school peers, they had a 45 percent greater rate of problems resulting from alcohol and marijuana use and a 40 percent higher level of actual use of those substances. They also had a 22 percent greater rate of adult criminal behavior, from theft to assaults.
Sadly, I have/had 5th graders that could be described as "psuedomature." I sure hope they figure it out before it's too late!
