visual search and attention
-
How people manage to find target objects in visual scenes is also a fascinating human ability. We have proposed a model for visual search that assumes people search through items one at a time, but that this is slow and serial search is aided by a parallel process that guides attention to items likely to be targets. This attention attraction can be disrupted by other aspects of the visual scene. For example, the sudden onset of items in the display tends to attract attraction. In current work, we are looking at how multiple calls for attention compete and/or cooperate with each other.
