Brains Hard-Wired for Math

Posted by samzenpus on from the easy-as-1-2-3 dept.

mcgrew writes "New Scientist is reporting that "non-human primates really can understand the meaning of numerals." The small study of two rhesus monkeys reveals that cells in their brains respond selectively to specific number values — regardless of whether the amount is represented by dots on a screen or an Arabic numeral. For example, a given brain cell in the monkey will respond to the number three, but not the number one. The results suggest that individual cells in human brains might also have a fine-tuned preference for specific numerical values." The report itself is online at PLoS Biology, Semantic Associations between Signs and Numerical Categories in the Prefrontal Cortex."

    My brain has a fine-tuned preference for the number 'one'.

    # I wonder if the brains are wired for specific bases, like base 10.

    We like it because we have ten fingers. Other civilizations have had other number systems though. The Mayans used base 20, since they had 20 fingers

    I've co-taught an undergraduate mathematics course. Based on this experience and many others, I assure you the human mind is not hard-wired for math.

  7. I really like seven... by feepness · · Score: 4, Funny

    For some reason I get aroused when I hear the number seven. Especially when it's followed by "of nine".

    There actually are 11 kinds of people - one kind doesn't get the joke, one kind does, and the other nine are sick to death of hearing it trotted out at every bloody opportunity.

    Did you just add footnotes to actually back up your claim on a slashdot discussion? *rubs eyes* You're going to destroy this site's reputation.

    There was one which used that system but it died out after the first generation. ;)

    these were non-numbered footnotes so they don't count.
