Dogs and wolves – fascinating research.

Something new to learn every day!

I have been saving this report for a few weeks.  Following yesterday’s great news about the latest concerning wolves in Oregon, today seemed a perfect follow-on with a report first published in online journal PLOS ONE. However, what follows is a full republication of the report as I read it on the Science Daily website.

Teaching young wolves new tricks: Wolves are considerably better imitators than dogs

Summary: Although wolves and dogs are closely related, they show some striking differences. Scientists have undertaken experiments that suggest that wolves observe one another more closely than dogs and so are better at learning from one another. The scientists believe that cooperation among wolves is the basis of the understanding between dogs and humans.

Although wolves and dogs are closely related, they show some striking differences. Scientists from the Messerli Research Institute at the University of Veterinary Medicine, Vienna have undertaken experiments that suggest that wolves observe one another more closely than dogs and so are better at learning from one another. The scientists believe that cooperation among wolves is the basis of the understanding between dogs and humans.

Their findings have been published in the online journal PLOS ONE.

Wolves were domesticated more than 15,000 years ago and it is widely assumed that the ability of domestic dogs to form close relationships with humans stems from changes during the domestication process. But the effects of domestication on the interactions between the animals have not received much attention. The point has been addressed by Friederike Range and Zsófia Virányi, two members of the University of Veterinary Medicine, Vienna (Vetmeduni Vienna) who work at the Wolf Science Center (WSC) in Ernstbrunn, Niederösterreich.

Wolves copy other wolves solving problems

The scientists found that wolves are considerably better than dogs at opening a container, providing they have previously watched another animal do so. Their study involved 14 wolves and 15 mongrel dogs, all about six months old, hand-reared and kept in packs. Each animal was allowed to observe one of two situations in which a trained dog opened a wooden box, either with its mouth or with its paw, to gain access to a food reward. Surprisingly, all of the wolves managed to open the box after watching a dog solve the puzzle, while only four of the dogs managed to do so. Wolves more frequently opened the box using the method they had observed, whereas the dogs appeared to choose randomly whether to use their mouth or their paw.

Watch closely …

To exclude the possibility that six-month old dogs fail the experiment because of a delayed physical or cognitive development, the researchers repeated the test after nine months. The dogs proved no more adept at opening the box than they were at a younger age. Another possible explanation for the wolves’ apparent superiority at learning is that wolves might simply be better than dogs at solving such problems. To test this idea, the researchers examined the animals’ ability to open a box without prior demonstration by a dog. They found that the wolves were rarely successful. “Their problem-solving capability really seems to be based on the observation of a dog performing the task,” says Range. “The wolves watched the dog very closely and were able to apply their new knowledge to solve the problem. Their skill at copying probably relates to the fact that wolves are more dependent on cooperation with conspecifics than dogs are and therefore pay more attention to the actions of their partners.”

The researchers think that it is likely that the dog-human cooperation originated from cooperation between wolves. During the process of domestication, dogs have become able to accept humans as social partners and thus have adapted their social skills to include interactions with them, concomitantly losing the ability to learn by watching other dogs.

So if you, like me, are one of many people who believe that your dog knows what you are thinking, then we need to thank the wolf!

Dogs ‘copy’ their owners

More evidence that shows there’s more to dogs than we realise.

Earlier on this year, a series of Posts was published on Learning from Dogs based on a science programme on the BBC (BBC Horizon) that revealed the degree of sophistication that is inherent in these clever animals.

This is the link to that article.  Unfortunately the YouTube videos have now been removed but there are some clips available on the BBC website here.  As the programme was introduced:

We have an extraordinary relationship with dogs – closer than with any other animal on the planet. But what makes the bond between us so special?

Research into dogs is gaining momentum, and scientists are investigating them like never before. From the latest fossil evidence, to the sequencing of the canine genome, to cognitive experiments, dogs are fast turning into the new chimps as a window into understanding ourselves.

Anyway, all this is a lead in to an item on the news today regarding a study into dogs by the University of Vienna.

Dogs “automatically imitate” the body movements of their owners, according to a study.

This automatic imitation is a crucial part of social learning in humans.

But Austrian researchers report that the phenomenon – where the sight of another’s body movement causes the observer to move in the same way – is evident in many other animals.

They say that it reveals clues about how this type of learning evolved.

The study, which was led by Dr Friederike Range from the University of Vienna in Austria, also suggests that the way in which people interact with and play with their dogs as they are growing up shapes their ability to imitate.

The phenomenon under investigation is known as "selective imitation" and implies that dogs -- like human infants -- do not simply copy an action they observe, but adjust the extent to which they imitate to the circumstances of the action. (Credit: iStockphoto/David Brimm)

There’s more to the news release on Science Daily from which is quoted:

New research by Friederike Range and Ludwig Huber, of the University of Vienna, and Zsofia Viranyi, of the Eötvös University in Budapest, reveals striking similarities between humans and dogs in the way they imitate the actions of others. The phenomenon under investigation is known as “selective imitation” and implies that dogs–like human infants–do not simply copy an action they observe, but adjust the extent to which they imitate to the circumstances of the action.
