Researchers: More Intelligent Jays Show More Self-Control
The researchers say that the same relationship holds true for cuttlefish, chimpanzees, and humansA recent study finds that Eurasian jays can pass a version of the “Marshmallow test” and that the smarter jays had the greatest self-control. The original Marshmallow test tested children to see if they could resist eating one marshmallow if they were offered two later. So enterprising researchers decided to try it on smart birds: To test the self-control of ten Eurasian jays, Garrulus glandarius, researchers designed an experiment inspired by the 1972 Stanford Marshmallow test — in which children were offered a choice between one marshmallow immediately, or two if they waited for a period of time. Instead of marshmallows, the jays were presented with mealworms, bread and cheese. Mealworms are a common favourite; bread and cheese come second Read More ›
