What do children make of robot dogs?

Whether something is living or not is a crucial distinction, and it's one that children already understand by the age of five. What then do children make of the latest generation of robot pets - toys designed to be as "alive" as possible? It's a surprisingly little researched area, but with the shuttle rate of technological advance in toy-land, it's one that's bound to become increasingly relevant.

Gail Melson and colleagues filmed 72 kids, aged 7 to 15 years, playing for 45 minutes with a Sony Aibo robot dog  and for 45 minutes playing with a real-life pooch of the Australian Shepherd breed. The Sony 210 Aibo dog was the most advanced robot dog at the time this research was conducted. It was capable of walking after a pink ball, kicking and headbutting it. It could also shake itself, sit down, lie down, offer its paw, learn, and display positive and negative emotion via lights.

As well as filming the children, the researchers also asked them questions about the biological (e.g. does X eat?), mental (e.g. can X feel happy?), and social (e.g. does X like you?) properties of the two dogs, as well as their moral standing (e.g. is it OK or not OK to hit X?).

The picture that emerged was mixed. On the one hand, the children clearly saw the real dog as more real and alive than the robot dog. They also examined the robot dog as if it were an object rather than a creature - prodding it and picking it up. On the other hand, there were signs that the children saw the robot dog as more than a mere toy. For example, over 80 per cent of the children spoke and gave commands to the robot dog as often as they did to the real dog. Nearly half the children petted the robot dog gently at least once, despite its metallic surface. Moreover, the children were no more likely to say it was okay to hit the robot dog than they were to say it was okay to hit the real dog! In all cases there was a trend for older children to see the robot dog as less real.

"These children were surprisingly willing to treat the robot dog as 'dog like'," the researchers concluded. "...[S]uch findings may be evidence of the emergence of a new ontological category, neither artifact nor living being."

I wonder how stuffed dogs would measure up...

I don't wonder about stuffed dogs much, I do however wonder about more visually animal-like robots. Fake fur, animal-like voices. Especially if they are not trying to pretend to be an existing animal, but something completely new (no, not furbys, or whatever they were named). I would love to find out if very small children who do not yet comprehend what a "real" animal is like would develop more or less of an uncanny valley if raised with artificial pets that do respond to and use interactions humans prefer (touching, body language and verbal cues).
