Visual search and dual tasks reveal two distinct attentional resources.
Most theories of visual processing assume that a target will "pop out" from an array of distractors ("parallel" visual search, e.g., color or orientation discrimination) if targets and distractors can be discriminated without attention. When the discrimination requires attention (e.g., rotated L vs. T or red-green vs. green-red bisected disks), "serial" examination is needed in visual search. A...
متن کاملBilateral attentional advantage on elementary visual tasks
We examined interactions between and within the left and right visual hemifields using elementary visual tasks. Each trial required identifying a letter at fixation and then either discriminating the orientation of (experiment 1) or detecting (experiment 2) peripheral Gabor targets. On half the trials Gabor distracters were presented between the Gabor targets, and were either restricted to one ...
متن کاملThe Complexity of Visual Search Tasks
One of the most frustrating things about studying attention is that research is so often is accompanied by vague discussions of capacity limits, bottlenecks, resource limits, allocations of attentional resources, and the like. How can these notions be made more concrete? The sub-area of computer science known as Computational Complexity is concerned with the theoretical issues dealing with the ...
متن کاملSegmentation of objects from backgrounds in visual search tasks 3
11 In most visual search experiments in the laboratory, objects are presented on an isolated, blank background. In most real world 12 search tasks, however, the background is continuous and can be complex. In six experiments, we examine the ability of the visual 13 system to separate search items from a background. The results support a view in which objects are separated from backgrounds in a ...
