Attentional Selection from Natural Scenes

Phelps Hall 3512

Abstract
. The visual system has an extraordinary capability to extract categorical information when searching complex natural scenes. For example, subjects are able to rapidly detect the presence of object categories such as animals or vehicles in novel scenes that are presented very briefly. In my talk, I will discuss recent studies that are aimed at elucidating the neural basis underlying such visual search at the level of object categories in the human brain. In addition, I will revisit the representation of categorical object information in two lesion models: in agnosia, when object-selective cortex is dysfunctional, and in amnesia, when major feedback input to object representations is interrupted.

Sabine Kastner is Professor of Psychology and the Princeton Neuroscience Institute at Princeton University. Dr. Kastner, Principal Investigator of the Neuroscience of Attention & Perception Laboratory, studies the neural basis of visual perception, attention, and awareness using a translational approach that combines neuroimaging in humans and monkeys, monkey physiology and studies in patients with brain lesions. A major long-term goal is to provide a neural basis for human visual attention in the framework of biased competition theory. She holds an M.D. from University of Dusseldorf and a Ph.D. from the University of Gottingen.

The objectives of the ThinkSpatial brown-bag presentations are to exchange ideas about spatial perspectives in research and teaching, to broaden communication and cooperation across disciplines among faculty and graduate students, and to encourage the sharing of tools and concepts.
Please contact Andrea Ballatore (893-5267, aballatore@spatial.ucsb.edu) to review and schedule possible discussion topics or presentations that share your disciplinary interest in spatial thinking.
