Study: Kids who are good liars score high on memory tests

Your kids lying to you may actually be a good thing? A new study from the University of North Florida found kids who are good liars also have better working memories -- especially verbal.

Researchers say it may be because it takes a good talker to keep one's lies straight. The children tested who were good liars had higher scores on memory tests. You can find the full study in this month's Journal of Experimental Child Psychology.
