What attributes guide the deployment of visual attention and how do they do it?
As you drive into the centre of town, cars and trucks approach from several directions, and pedestrians swarm into the intersection. The wind blows a newspaper into the gutter and a pigeon doesExpand

Low target prevalence is a stubborn source of errors in visual search tasks.
In visual search tasks, observers look for targets in displays containing distractors. Likelihood that targets will be missed varies with target prevalence, the frequency with which targets areExpand

How fast can you change your mind? The speed of top-down guidance in visual search
Most laboratory visual search tasks involve many searches for the same target, while in the real world we typically change our target with each search (e.g. find the coffee cup, then the sugar). HowExpand

Cognitive psychology: Rare items often missed in visual searches
We show that target rarity leads to disturbingly inaccurate performance in target detection: if observers do not find what they are looking for fairly frequently, they often fail to notice it when it does appear. Expand

Tracking unique objects
Is content addressable in the representation that subserves performance in multiple-object-tracking (MOT) experiments? We devised an MOT variant that featured unique, nameable objects (cartoonExpand

Visual attention.
A typical visual scene we encounter in everyday life is complex and filled with a huge amount of perceptual information. The term, 'visual attention' describes a set of mechanisms that limit someExpand

[General method].
Stimuli: The target was either a mirror-reversed "P" or a mirror-reversed "S." Distractors were drawn from the rest of the alphabet. Task: Report the color of the target when you found it. UnspeededExpand

Why is visual search superior in autism spectrum disorder?
This study investigated the possibility that enhanced memory for rejected distractor locations underlies the superior visual search skills exhibited by individuals with autism spectrum disorderExpand

Using fMRI to distinguish components of the multiple object tracking task.
Multiple object tracking (MOT) has proven to be a powerful technique for studying sustained selective attention. However, surprisingly little is known about its underlying neural mechanisms. PreviousExpand

The role of location and motion information in the tracking and recovery of moving objects
Observers in a multiple object tracking task can track about four to five independently moving targets among several moving distractors, even if all of the stimuli disappear for a 300-msec gap. HowExpand
