capital, neurobiological and economic

In her look at neural plasticity, Jessa Gamble observes that when "careers require years of internships and graduate degrees, the age of adulthood is receding, practically into the 30s:"

Adolescence, loosely defined as the period between puberty and financial independence, now lasts about 15 years, twice as long as it did in the 1950s [...] when an increasing number of young people are still dependent on their parents. There is some concern that all of this dependence could lead to a lasting immaturity and failure to take on responsibility.

On a positive note, Gamble writes that "according to developmental researchers, there is one lasting gift that extended adolescence can bestow, and it resides in the brain:"

"Neurobiological capital" is built through a protracted period of learning capacity in the brain, and it is a privilege that comes to those lucky enough to enjoy intellectually stimulating environments in late adolescence. Far from a contributor to emotional immaturity, the trend toward an adolescence that extends into the mid-20s is an opportunity to create a lifelong brain-based advantage.


"Some of this evidence," she writes, "comes from brain studies of those who have had access to higher education:"

The window for developing self-regulation closes when adult life settles into a routine, and the brain begins to exchange growth for efficiency. But if an adolescent continues to be stimulated intellectually--through higher education or travel, for example--their brain remains in its formative stage into the mid-20s, and even primes itself for future learning in adulthood. Dubbed "metaplasticity," changing brain circuits through learning during adolescence can make subsequent modifications easier in those areas.

There is, of course, a cost that makes this stimulation an "economically exclusive" prospect:

Protracted brain plasticity often depends on access to a stimulating environment--and the money that entails. Instead of falling into the rote tasks of an entry-level position after college, a debt-free graduate might volunteer overseas for a year and learn a new language and culture.

To maximize neurobiological capital, it soon may not be enough for parents to sock away money in college savings accounts. Some may need to budget for a Neurobiological Runway Fund to cover the post-college years, too.
