recently, more worked as herders or retrievers. As more ended up being animals instead of employees, pets might acquire more understanding of words that represent items.
The scientists question how other mammals may carry out in comparable tests. Boros likewise states comparable experiments might be carried out utilizing fMRI — however it’s much more difficult to train canines for such research studies. It can use up to 6 months to prepare them for such work.
Boros states these sort of research studies can reveal what people share with animals and what sets us apart. “It’s not insignificant about what is shared amongst all mammals and what it distinctively human,” she states. “We put ourselves on a pedestal, and after that it ends up that we are not so distinct after all.”
