In That Tucked Tail, Real Pangs of Regret?

[elleng]

If you own a dog, especially a dog that has anointed your favorite rug, you know that an animal is capable of apologizing. He can whimper and slouch and tuck his tail and look positively mortified — “I don’t know what possessed me.” But is he really feeling sorry?

. . .

Yet as new reports keep appearing — moping coyotes, rueful monkeys, tigers that cover their eyes in remorse, chimpanzees that second-guess their choices — the more I wonder if animals do indulge in a little paw-wringing.

Your dog may not share Hamlet’s dithering melancholia, but he might have something in common with Woody Allen.

The latest data comes from brain scans of monkeys trying to win a large prize of juice by guessing where it was hidden. When the monkeys picked wrongly and were shown the location of the prize, the neurons in their brain clearly registered what might have been, according to the Duke University neurobiologists who recently reported the experiment in Science.
