B-Brains (SOM Section 6.4)
Any part of the brain connected not
to the outside world, but only to another part of the
same brain. Like a manager, a B-brain can supervise
and A-brain without understanding either how the A-brain
works or the problems with which the A-brain is involved
-- for example, by recognizing patterns of activity that
indicate the A-brain is confused, wasting time in repetitive
activity, or focused on an unproductive level of detail
Papert's Principle (SOM Section 10.4)
Some of the most crucial steps in mental growth
are based not simply on acquiring new skills, but on
acquiring new administrative ways to use what one
already knows.
