Ever since the late-1990s, when researchers discovered that the human brain takes into our mid-20s to fully develop — far longer than previously thought — the teen brain has been getting a bad rap. Teens, the emerging dominant narrative insisted, were “works in progress” whose “immature brains” left them in a state “akin to mental retardation” — all titles from prominent papers or articles about this long developmental arc.
In a National Geographic feature to be published next week, however, I highlight a different take: A growing view among researchers that this prolonged developmental arc is less a matter of delayed development than prolonged flexibility. This account of the adolescent brain — call it the “adaptive adolescent” meme rather than the “immature brain” meme — “casts the teen less as a rough work than as an exquisitely sensitive, highly adaptive creature wired almost perfectly for the job of moving from the safety of home into the complicated world outside.” The teen brain, in short, is not dysfunctional; it’s adaptive. (See Carl Zimmer’s recent column for a rare look at this idea.)
An interesting idea and new perspective. Flexibility higher among teens than among adults, which makes sense. Also it chimes with my thinking of adaptability growing with age. Cite this one!
