Toy shapes may help kids learn words faster

LOS ANGELES That's according to University of Iowa researchers, who conducted a study of 16 children 18 months old.

The toddlers knew the names of about 17 objects, but those who played with different shaped toys learned nearly 10 new words per week, while those who played with similar objects only learned four words.

The study is published in the December issue of Psychological Science.
