At puberty, however, the brain shuts down half of that capacity, preserving only those modes of thought

16、 that have seemed most valuable during the first decade or so of life.The current emphasis on standardized testing highlights analysis and procedure, meaning that few of us inherently use our innovative and collaborative modes of thought. This breaks the major rule in the American belief system - th
