Response 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 کاملConditioned fear modulates visual selection.
Eye movements reflect the dynamic interplay between top-down- and bottom-up-driven processes. For example, when we voluntarily move our eyes across the visual field, salient visual stimuli in the environment may capture our attention, our eyes, or modulate the trajectory of an eye movement. Previous research has shown that the behavioral relevance of a salient stimulus modulates these processes...
متن کاملMasking within and across visual dimensions: psychophysical evidence for perceptual segregation of color and motion.
Visual masking can result from the interference of perceptual signals. According to the principle of functional specialization, interference should be greatest when signal and mask belong to the same visual attribute (e.g., color or motion) and least when they belong to different ones. We provide evidence to support this view and show that the time course of masking is visual attribute specific...
متن کاملVisual search — 1 VISUAL SEARCH ACROSS THE LIFE SPAN
The focus of this study was to evaluate the gains and losses in visual search performance across the lifespan in a representative sample of 298 individuals ranging from 6 to 89 years of age. Adopting a lifespan developmental perspective, two general resource theories were considered: cognitive speed and inhibitory control. Participants searched computer displays to indicate the presence or abse...
