Giedd, chief of the Brain Imaging Section of the Child Psychiatry Branch at the National Institute of Mental Health, is also the recipient of the BBRF's 2013 Ruane Prize for Outstanding Achievement in Child and Adolescent Psychiatric Research.
The major benefit of adolescence, Giedd explained, is a slowly maturing brain that makes humans more adaptable and more open to change than if their brains had matured more rapidly. The Neanderthals, in contrast, had a less-protected period of adolescence. Their brains matured rapidly, and they quickly grew into adults, yet the downside was that they did not adapt well and eventually became extinct, he said. Moreover, because the adolescent brain is in the process of maturing, teens tend to be much more adaptable and more at home with the dizzying advances of the digital revolution than adults are, Giedd noted.
More information about human adolescence and Giedd's view of this developmental stage is in the Psychiatric News article "Prolonged Adolescence Helps Build a Better Brain." Information about adolescent development from a psychodynamic perspective can be found in the new American Psychiatric Publishing book Normal Child and Adolescent Development: A Psychodynamic Primer.
