Comparative vision: mid-level processing of form and motion in humans and pigeons

• Author / Creator

• The ability to perceive and act upon the external world is fundamental to every organism. For species such as humans and pigeons, vision is a dominant modality that allows interaction with the world. In this dissertation I examine the similarities and differences between humans and pigeons, two distantly related species that share the common problem of perceiving an object‐filled world. Specifically, results are presented from a series of studies examining how form and motion interact and how they contribute to object perception at the intermediate level of visual processing. The similarities and differences in form and motion perception in humans and pigeons are discussed with respect to similarities and differences in neuroanatomy and with respect to evolutionary adaptation. The research presented in this dissertation provides evidence to further the current understanding of the general principles of object perception and vision in general.
