| Research Abstract |
I studied how animals including humans and avian species have developed perceptual ability to identify moving objects in their environments by comparing motion perception between pigeons and humans. I have found a species difference in perception of multiple moving objects between pigeons and humans. Humans have a strong tendency to perceptually organize multiple objects, but pigeons do not. I also have found that both pigeons and humans can detect expanding stimuli more easily than contracting ones. Taking the fact that approaching and receding objects generate expanding and contracting images on the observer's retina into account, both pigeons and humans may be sensitive to approaching objects.
