Seminar Series

60 Oxford Street, Room 330
Jeremy M. Wolfe, Professor of Ophthalmology, Harvard Medical School
Seminar Title: Visual Search: Is it a Matter of Life and Death?
Abstract
I will give an introduction to the problem of visual search and to
the Guided Search model that my lab has been working on for a number
of years. I will discuss an important practical problem in search.
Rare targets are hard to find simply because they are rare. We ask
people to find rare targets in some very important tasks like baggage
screening and routine mammography so, if low target prevalence makes
search difficult, this could be a real problem. Finally, I will place
the problem of search into the larger context of visual perception
and show how our need to use selective attention leads to some
interesting perceptual errors.
