Infants can't distinguish between large and small groups
Date:6/19/2012

p has old evolutionary roots. Dozens of species, including some fish, monkeys and birds have shown the ability to recognize numerical differences in laboratory studies. VanMarle speculated that being unable to compare large and small sets early in infancy may not have been problematic during human evolution because young children probably received most of their food and protection from caregivers. Infants' survival didn't depend on determining which bush had the most berries or how many predators they just saw, she said.

"In the modern world there are educational programs that claim to give children an advantage by teaching them arithmetic at an early age," said vanMarle. "This research suggests that such programs may be ineffective simply because infants are unable to compare some numbers with others."
