Contrary to previous studies, pigs appear to have better visual discrimination abilities than had previously been assumed. Cognition researchers from the Messerli Research Institute showed in a new study that pigs not only discriminate between front and back views of human heads but also that the animals apparently use certain facial features such as our eyes or mouth as cues. The results shed a new, more positive light on the previously rather pessimistic opinion of the visuo-cognitive abilities of these clever animals.
