No, such beliefs were perhaps entertained by Descartes. But to assume that humans are separate from animals in our conscious perception of the world and our agency flies completely in the face of our understanding of basic biology, from genetics, developmental biology, to neurophysiology. We could claim that all other human beings aren't conscious as well, and that any reactions are affective only. It's clearly not serious, but claiming the same about mammals and other higher vertebrates can't be serious either given their extremely close biological similarity. It is extremely unlikely that they aren't as entirely as aware of the world as ourselves, and it is not logical to assume there is some fundamental cognitive difference when our observations show such close similarity.
