Behavioral Science Turns to Dogs for Answers

From Spiegel Online.

What may seem like simple amusement for Guinness and her fellow canines is in fact revolutionizing cognitive research. Range is the first animal researcher to attempt to lure domestic dogs to a touch screen. Scientists in her field have spent decades working with pigeons pecking at pictures, conversing with apes using brightly colored touch symbols, and listening in on the grunting noises made by seals. But the talents of Canis familiaris remained largely unexplored.

"Dogs can do things that we long believed only humans had mastered," says Juliane Kaminski of the Max Planck Institute (MPI) for Evolutionary Anthropology in the eastern German city of Leipzig.

"When it comes to understanding human behavior, no mammal comes even close to the dog," says Kaminski. Her Leipzig research team has demonstrated that dogs are far better than the supposedly clever apes at interpreting human gestures.

The researchers held two containers, one empty and the other containing food, in front of chimpanzees and dogs. Then they pointed to the correct container. The canines understood the gesture immediately, while the apes, genetically much more closely related to humans, were often perplexed by the pointing finger.

That's not all. Many dogs were even capable of interpreting the researcher's gaze. When the scientists looked at a container, the dogs would search inside for food, but when they looked in the direction of the container but focused on a point above it on the wall, the dogs were able to understand that this was not meant as a sign.

Dogs are so geared toward communication with people that it seems to run in their genes. Kaminski and her fellow researchers repeated the pointing experiment with six-week-old puppies. Astonishingly, even the puppies understood immediately that it was worth investigating the area the human finger was pointing to.

Range has already shown that dogs use a learning strategy -- selective imitation -- that, until recently, was believed to be unique to human children once they turned a year old. She taught her own dog to push a handle to open a food dispenser. Every dog would instinctively use its snout to push on such a device. But Guinness was only rewarded when she used her paw.

Once Guinness had learned the technique, individual dogs were brought in to observe her. If Guinness had a ball in her mouth, so that it was obvious that she could not use her snout, most of the observers pushed on the handle with their snouts. But when they saw Guinness without a ball they usually used their paws. If Guinness chose the more difficult method for no apparent reason, the dogs apparently concluded that there must be some advantage to this behavior.

Young children behave in a similar way.

Nowadays dog owners send their beloved pets to agility training, where they balance on ramps and crawl through tubes. Some dogs attend "dog dancing" sessions, and puppy training has become all the rage. "Dog education has changed," says Range.

Border collies like Rico and Guinness would probably be happiest watching over their own herds of sheep. "They simply want to work," says Range. American dog researcher Stanley Coren is convinced that the border collie is the most intelligent of the roughly 400 breeds of dog.

As clever as dogs are when it comes to all things relating to their masters, they fail miserably when logic comes into play.
