The present paper outlines a framework which allows a consistent interpretation of data
regarding visual selection in visual search tasks. It organizes and reviews visual search …

Four visual search experiments examined the allocation of attention in a multi-item display
with a salient stimulus difference. If, irrespective of its relevance to performance, an item with …

Research on visual attention deals with the limit on our ability to identify several stimuli at
once. In visual search, this leads to concern with both the number of targets and the number …

Previous studies have shown that simple reaction times (RTs) to a visual target are
facilitated when the target occurs at a location expected by an observer and are slowed …
