Feature integration across parts in visual search.
In the present study, participants searched for a conjunction of color and orientation either from the same part of an object (same-part display), or from different parts of an object (different-part display). While no difference was found between the two display conditions in single feature searches, conjunction search in the same-part display was significantly faster than that in the differen...
متن کاملResponse selection modulates visual search within and across dimensions.
In feature search tasks, uncertainty about the dimension on which targets differ from the nontargets hampers search performance relative to a situation in which this dimension is known in advance. Typically, these cross-dimensional costs are associated with less efficient guidance of attention to the target. In the present study, participants either had to perform a feature search task or had t...
متن کاملWithin and cross dimensions 1 Running Head: WITHIN AND CROSS DIMENSIONS Response Selection modulates Visual Search Within And Across Dimensions
In feature search tasks, uncertainty about the dimension on which targets differ from the surrounding nontargets hampers search performance relative to a situation in which this dimension is known in advance. Typically these cross-dimensional costs are associated with less efficient guidance of attention to the target. In the present study participants either had to perform a visual search task...
متن کاملSalience from feature contrast: additivity across dimensions
Test targets ('singletons') that displayed orientation, motion, luminance, or color contrast, or pairwise combinations of these, were presented in line texture arrays, and their saliences were quantified in comparison to reference targets at defined luminance levels. In general, saliency effects in different stimulus dimensions did add, but did not add linearly. That is, targets with feature co...
متن کاملFeature Conjunctions in Visual Search
Selective Tuning (ST) [1] presents a framework for modeling attention and in this paper we show how it performs in visual search tasks. Two types of tasks are presented, a motion search task and an object search task. Both tasks are successfully tested with different feature and conjunction visual searches.
