Episodic memory allows you to remember the event information with reference to time and place, in some respects, is considered a unique human ability. In particular, people often remember the episodes, the memory of which, at first glance, does not represent for them any practical value. A recent study has shown that this ability is not alien to the dogs.
According to scientists from Hungary, is still the question of whether dogs are “episodic” memory, was not considered too carefully because the answer to this question is not so difficult — it is known that dogs can carry the team, but in this situation they know that the memories will be useful to them, and it is somewhat different.
During the investigation the specialists have trained 17 dogs simple game of “do as I do”, the essence of which was that the man was producing some action (for example, Bouncing up and down) saying “do it” and the dog was produced as similar movement that was capable of. After that dogs taught to lie down on the Mat in response to certain actions. When both skills were honed, the scientists moved to the main experiment. They drew the attention of the dog and performed an action — for example, dealt with one of those in the room items. After that, the dog was taken away for the screen and for some time she had not seen this item. Returning to the place the dog is obeying the scientist lay on the carpet, and then the experimenter said “do it.” As it turned out, the dogs knew what they wanted, and repeated the actions of the people despite the obvious reasons to remember these actions in dogs was not, and since they were distracted. To accomplish the task the dog even managed an hour, but eventually the “unnecessary” memories and become less bright.
Experts say that their findings indicate the similarity of episodic memory in dogs, and this, in turn, makes us re-think about the fact that the difference between man and many animals, in some respects, continues to be overrated.
