Susan Goldin-Meadow: I think that gestures might help children learn, and in fact encouraging parents to gesture to their children, I think is a good thing.

You're listening to psychologist Susan Goldin-Meadow of the University of Chicago. [---1---]

Susan Goldin-Meadow: [---2---]

Goldin-Meadow also discovered a connection between gesturing and socioeconomic status, or SES. [---3---]

Susan Goldin-Meadow: [---4---] Those gestures go on to predict the size of the children's vocabulary at 54 months, their spoken vocabularies.

Pre-school vocabulary, said Goldin-Meadow, is a key indicator of how successful they'll be in school.

Susan Goldin-Meadow: we can trace those gestures in the children back to the way the parents gesture at 14 months. So parents in high SES families tend to produce more different kinds of meanings with their gestures than parents who are from lower SES families.

Goldin-Meadow led research that found that children have bigger vocabulary when they're raised by parents who actively gesture — point, wave, and nod. We've looked at children from a wide demographic range, we found that children at 14 months already look different. She and her colleagues videotaped 50 children talking and gesturing with their families, whose education and incomes varied. Children from high SES homes gesture more, actually they produce more different kinds of meanings with their gestures at 14 months than children from low SES homes. Gestures don't have to be anything new for parents to learn, they can just use their hands more when they talk to their kids.
