Temple Grandin, autistic designer of cattle handling systems, said that one reason she can easily figure out how a cow would react is because autistic people can easily "think the way that animals think."[22] According to Grandin, animals do not have "complex emotions such as shame or guilt" and they do not think in language. She says that, although not everything about animals is like an autistic person, the similarity is that they think visually and without language. She says people do not make this connection because the study of autism and the study of animal behavior are parallel disciplines involving different individuals.[22] Despite these similarities, the degree to which autistic individuals can be said to think like animals remains undetermined; non-human animals, as well as humans, have evolved cognitive specializations that may or may not share characteristics with other species.[23]
