Dogs won't give food to a human, even if that person gave them some food first, and that they would help other dogs that had helped them before. Therefore, the team Previous studies have shown that dogs can recognize cooperative and uncooperative humans, "reciprocal altruism"- that is, doing a good thing in return to a human who had given expected to find that their test subjects would put these two things together and show To start, the team trained a group of 37 dogs to press a button which would activate a them food first. *enclosure with the dispenser, while one of (2) two humans was in a separate enclosure with the button.

After that, the researchers switched over the button and the dispenser. They expected that the dogs would press the button to give food to the helpful human but not to the though the dogs did press the button, they did it just as often when either human had the food dispenser, and even when no human was there at all. "In these kinds of studies (5) [perform / to / dogs / which/ trained / are in a particular behavior for an experiment, they will usually do the behavior a few times as they have simply learned the association between the behavior and getting a reward, and it may be enjoyable for them to do the behavior," said Jim McGetrick, a PhD student at the University of Veterinary Medicine in Vienna who led the research. 身を正しく が本冊子 1番 2 次の英文を読んで下の設問に答えなさい。 (3) giving us some food?

McGetrick believes there is possible that the dogs did not understand enough about the task to realize that only one of the humans was providing them with food," he said. It could also be because they didn't fully understand the button and dispenser system, or because they were too focused on the food to notice whether a particular human was pressing the button or not. "Having said all that, even if they did completely understand the task and were fully attentive to the actions of the humans, there is still a good possibility that they wouldn't have given food back in return," he added.
