Showing dogs the opposite half of the face to the half they had learned to recognise in their training, showed they could "transfer their knowledge" of human facial expressions.
研究人员给狗狗们展示它们在训练中所辨认的半张面部图片的另一半,结果表明它们对人类面部表情的知识可以“活学活用”。
"So, for example, in the training, they see the mouth region of the happy face," said Prof Huber, "and they associate that with what the eyes would look like."
“比如,举个例子,在训练中,它们看到了笑脸的嘴部区域,”胡贝尔教授说,“然后它们能将其与看上去对应的眼睛联系起来。”
This study, published in the journal Current Biology, is part of a larger project studying how humans and their canine companions interact.
这项研究发表在《当代生物》(Current Biology)杂志上,是一项关于人类与狗如何互动的大型研究课题的一部分。
Dr Kun Guo, a psychologist and expert in human-animal interaction from the University of Lincoln, said: "Showing dogs only half of the face and then the other half separately means they can't rely on the shape of the eyes or the mouth - they must have some sort of template in their mind.
林肯大学(University of Lincoln)心理学家及人与动物相互关系专家昆·郭(Kun Guo)博士表示:“先让狗狗看半张脸部图片,然后再看另半张,这就意味着它们不能依靠眼睛或嘴巴的形状来辨别表情——它们的脑海中一定有某种样板。”
