What are the units of attention? In addition to standard models holding that attention can
select spatial regions and visual features, recent work suggests that in some cases attention …

This tutorial provides a selective review of research on object-based deployment of
attention. It focuses primarily on behavioral studies with human observers. The tutorial is …

Much of the research in visual attention has been driven by the spotlight metaphor. This
metaphor has been useful over many years for generating experimental questions in …

A large body of evidence suggests that visual attention selects objects as well as spatial
locations. If attention is to be regarded as truly object based, then it should operate not only …

The way the cognitive system scans the visual environment for relevant information–visual
search in short–has been a long-standing central topic in vision science. From its inception …

The objective of this paper was to investigate under what conditions object-based effects are
observed. Recently, Watson and Kramer (1999) used a divided-attention task and showed …

There is now much experimental evidence supporting the idea that visual attention can be
deployed in at least two ways: one space-based and other object-based. However, it is not …

Earlier studies have shown that attention can be directed to objects, defined on the basis of
generic grouping principles, highly familiar shapes, or task instructions, rather than to …

Previous studies have concluded that object-based attention does not always arise if
attention is cued endogenously (Macquistan, 1997) or if the target location is known with …
