Computer-savvy canines

In the second test, the dogs were shown new dog pictures pasted onto the landscape pictures used in the training phase, facing them with contradictory information: on the one hand, a new positive stimulus as the pictures contained dogs even though they were new dogs; on the other hand, a familiar negative stimulus in the form of the landscape. When the dogs were faced with a choice between the new dog on the familiar landscape and a completely new landscape with no dog, they reliably selected the option with the dog. These results show that the dogs were able to form a concept i.e. 'dog', although the experiment cannot tell us whether they recognized the dog pictures as actual dogs.

Dog, dog, dog, dog, dog. Sorry, I thought it had to be said a few more times. :)
