Models of visual attention have, with few exceptions, suggested that attention is deployed to
unitary regions of visual space. Kramer and Hahn (1995) recently reported that attention is …

In an effort to examine the flexibility with which attention can be allocated in visual space, we
investigated whether subjects could selectively attend to multiple noncontiguous locations in …

Although in traditional attention research the focus of visual spatial attention has been
considered as indivisible, many studies in the last 15 years have claimed the contrary …

It is still a matter of debate whether observers can attend simultaneously to more than one
location. Using essentially the same paradigm as was used previously by NP Bichot, KR …

Must attention be disengaged from a location before it can be moved to another? We
addressed this question in four experiments. Participants searched for a target defined by its …

A popular metaphor for visual attention is that of a spotlight that enhances perceptual
processing within its beam. Many studies on the orienting of visual attention have addressed …

According to object-based theories of visual attention can be divided within a single object
more efficiently than between separate objects (J. Duncan, 1984). Recently, GC Baylis and …

The representation within which attention operates was investigated in 3 experiments. The
task was similar to that of R. Egly, J. Driver, and RD Rafal (1994). Participants had to detect …

If we practise letting our attention wander over the different parts of the field of vision while
keeping the same fixation-point, it will soon become clear to us that the fixation-point of …

Experiment 1 used a modified spatial cueing paradigm that was introduced by Egly et al.[J.
Exp. Psychol. Gen. 123 (1994) 161] to investigate the cost incurred in shifting attention within …
