While we know that dogs evolved from wolves through a process of domestication, it remains unclear how this process may have affected dog cognitive development. Here we tested dog (N=44) and wolf (N=37) puppies, 5-18 weeks old, on a battery of temperament and cognition tasks. Dog puppies were more attracted to humans, read human gestures more skillfully and made more eye contact with humans than wolf puppies. The two species were similarly attracted to objects and performed similarly on nonsocial measures of memory and inhibitory control. These results demonstrate the role of domestication in enhancing the cooperative communication skills of dogs through selection on attraction to humans, which altered developmental pathways.

与人类的合作交流逐渐发展为在狗中早期出现

虽然我们知道狗是通过驯化过程从狼进化而来的,但仍不清楚该过程如何影响狗的认知发育。在这里,我们测试了5-18周大的狗(N = 44)和狼(N = 37)幼犬,进行了一系列的气质和认知任务。与狼幼犬相比,狗幼犬更容易吸引人,更能熟练地读取人的手势,并与人更多地眼神交流。这两个物种被类似地吸引到物体上,并且在记忆和抑制控制的非社会措施上表现相似。这些结果表明驯化通过选择对人的吸引力来增强狗的合作交流能力,从而改变了发育途径,从而发挥了作用。
