She Knew the New Rule. She Played by the Old One Anyway.

I told my daughter the sorting rule had changed. She repeated it back correctly, then sorted the next card by the old rule anyway. I used to think that meant she wasn’t listening. What the research on cognitive flexibility in children shows is a lot more specific, and a lot less worrying, than that.

Willpower Is Not the Skill. Knowing What to Do Instead Is

I kept telling my daughter to use her willpower. It never worked. Then I found out what separated the children who waited longest in Walter Mischel’s original studies, and none of it involved trying harder or gritting their teeth. Self-control in young children looks a lot more like redirection than resistance.
