Quote from Maverick1:
Great article. This is the paragraph that caught my attention:
"Cloninger has trained rats and mice in mazes to have persistence by carefully not rewarding them when they get to the finish. âThe key is intermittent reinforcement,â says Cloninger. The brain has to learn that frustrating spells can be worked through. A person who grows up getting too frequent rewards will not have persistence, because theyâll quit when the rewards disappear.â
