but I can deal with it' but if a child has been too underchallenged for too long, they start to act as though that acceptable challenge range collapses into a skinny line - everything is boringly easy or impossible.

Interesting and relevant for me to read this today. DD was complaining earlier in the year that math (she is accelerated a full grade this year) is too hard, impossible, etc. (She is getting As, but also is getting things wrong sometimes, which is new.) They've recently been doing some material she finds easier and now she's complaining that it's boring, too easy, etc. DD!! Two weeks ago you were sobbing about how you were no good at math!! WTH?
