【汪星人可以帮你找丢失的东西了】朴茨茅斯大学的研究人员通过对48只狗狗的研究发现当你丢失东西时,狗狗会知道,它甚至有一种特殊的本领,知道你在找什么,并且将长时间观察一个地方尽量会把你的注意力吸引到你丢失的东西上,从而帮助你找到它。

If you can’t remember where you put your keys, try asking the dog: Canines understand when humans have misplaced something valuable

  • Dogs can help us to find lost objects by drawing our attention to them
  • In a study of 48 dogs, researchers found they helped to find an object
  • The animals spent more time looking at an opaque tub containing it
  • Findings suggest dogs can work out values of objects based on our need

For the more forgetful among us, it would seem that dogs really are man’s best friend.

A study has shown that pet dogs seem to be able to understand when we have misplaced something that is valuable to us.

And they do what they can to try to help us find it – at least in the lab.

The University of Portsmouth research is important because it had previously been argued that helpfulness was a uniquely human trait.

Researcher Patricia Piotti began by writing in a notepad while a pet dog watched her.

 

She then left the room and the dog watched while either the notepad or a stapler was hidden in one of three opaque tubs.

When Ms Piotti, a vet, came back in, she pretended to search for the object, and in some cases, she spoke to the dog, asking questions such as ‘Where is it?’ and ‘Where has it gone?’.

The 48 dogs tested were more likely to draw her attention to the only tub with an object inside.

And they looked longer at the tub holding the notebook, than the one with the stapler.

Hearing the researcher talk about her search also seemed to spur them on.

With no tasty treats or other rewards on offer, Ms Piotti said the fact that the dogs tried to draw her attention more to the notepad which they had seen her use, than to the stapler, suggested they were trying to be helpful.

She said: ‘Dogs have outstanding abilities when it comes to communicating with humans.

‘One theory is that they have adapted to life with humans by evolving specialised cognitive skills for interacting with people.

‘There seems to be some evidence that dogs could be able to distinguish between objects based on a human’s need for them.’

She added that further work is needed to prove that the notebook-hunting dogs were actually trying to be helpful and not simply playing a version of ‘fetch’.

However, before you ask Fido to help you find your car keys or your spectacles, you should ensure none of his toys are nearby.

In another experiment, Ms Piotti found that the dogs were far more interested in finding hidden toys than her missing notebook.

Her research is reported in the journal PLOS ONE.
