When Kids Imitate Others, They’re Just Being Human

"I heard it for the first time a few days ago: 'She’s copying me!” my 4-year-old wailed in a righteous complaint about her little sister. And she most certainly was copying, repeating the same nonsense word over and over. While it was distressing to my older kid, I thought it was funny that it took her so long to realize her sister copies almost everything she does. This egregious violation occurred just after I had read about an experiment that pitted young kids against bonobos in a test to see who might copy other individuals more. I’ll get right to the punch line: Kids won, by a long shot. The results, published online July 24 in Child Development, show that despite imitation annoying older siblings everywhere, it’s actually really important."
