How dogs don't ape

A distinguishing feature of human intelligence is our ability to understand the goals and intentions of others. This ability develops gradually during infancy, and the extent to which it is present in other animals is an intriguing question.

New research by Friederike Range and Ludwig Huber, of the University of Vienna, and Zsofia Viranyi, of the Etvs 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 dogslike human infantsdo not simply copy an action they observe, but adjust the extent to which they imitate to the circumstances of the action. The research will appear online on April 26th in the journal Current Biology, published by Cell Press.

In the study, dogs were faced with the task of opening a container with food by pulling a rod. Whereas dogs prefer to use the mouth for this task, a female dog was trained to open the box with her paw. When the other dogs observed the females action, they imitated it in order to get the food. However, the dogs imitated selectively. They used their mouths instead of their paws for manipulating the rod when they had seen the demonstrating dog using her paw while holding a ball in her mouth. However, when the demonstrating dogs mouth was free, the dogs imitated her action completely and used the paw themselves.

This means that the way the dogs imitate is tuned to the goal of the action. If the dogs perceive the demonstrator being unable to use her mouth, because she holds a ball in it, they choose the easier, more preferred way to achieve the goal. But when the mouth is free, there appears to be a reason for the demonstrating dog not to use her mouth, and so the dogs imitate the action.

The new work shows for the first time that animals do imitate selectively. This reveals a striking parallel between dogs and human infants in tha
