Rats Regret Their Decisions, Study Finds
PBS:
We bemoan our decisions when we get a bad deal or miss out. New research published in the journal Nature Neuroscience this week finds that regret may not be just a human emotion. It turns out rats also experience regret.
Researcher David Redish at the University of Minnesota in Minneapolis set up a “restaurant row” for his lab rats. The “restaurants” consisted of four stops where the rat could receive one option of his favorite flavor foods — banana, cherry, chocolate and a fourth unflavored food. The rat stops at the entrance and presses a button, which made a sound. The pitch indicated how long the rat needed to wait for food, anywhere from one to 45 seconds. If the rat was impatient, it could walk to the next stop and try again. However, each rat had an hour to get through the course, so it needed to be efficient.
