In the last decades several studies have been investigated the behavior and cognition of dogs (Canis familiars) especially from socio-cognitive aspects. We already gained a solid knowledge on how dogs communicate with humans and conspecific partners, how they are able recognize, interpret and rely on social-communicational cues in their everyday lives, thus continuously perceiving a flow of visual information. However, the fundaments of how they process these visual information are still missing from the literature. The current PhD project have been developed around three independent studies, all of them investigating visual cognition in dogs (and for one case, also in humans) in the domain of perceiving motion.
