Baby brains are hard-wired for math

Experiment indicates that infants recognize apparent errors in subtraction.

Next time someone complains about arithmetic being hard, math lovers can defend themselves by saying "even a 6-month-old can do it."

Through monitoring the brains of infants, researchers confirmed that infants as early as 6 months in age can detect mathematical errors, putting to rest a debate that has gone on for over a decade.

A team of scientists from the United States and Israel exposed 24 infants to a videotaped puppet show. They used the puppets for addition and subtraction while observing the reaction of the babies.

For example, they started the show with two dolls. Before the show ended, a doll was removed and then the infant's vision was blocked with a screen. When the screen was taken away, either one doll was left, as expected, or two dolls, which would not be mathematically correct.

The infants looked at the screen longer (8.04 seconds) when the number of dolls was two, which did not agree with the solution of 2 – 1 = 1.
