Feature-based attention is independent of object appearance.
How attention interacts with low-level visual representations to give rise to perception remains a central yet controversial question in neuroscience. While several previous studies suggest that the units of attentional selection are individual objects, other evidence points instead toward lower-level features, such as an attended color or direction of motion. We used both human fMRI and psycho...
متن کاملHow Prevalent Is Object-Based Attention?
Previous research suggests that visual attention can be allocated to locations in space (space-based attention) and to objects (object-based attention). The cueing effects associated with space-based attention tend to be large and are found consistently across experiments. Object-based attention effects, however, are small and found less consistently across experiments. In three experiments we ...
متن کاملFeature-based attention modulates the perception of object contours.
Feature-based attention is known to support perception of visual features associated with early and intermediate visual areas. Here we examined the role of feature-based attention in higher levels of object processing. We used a dual-task design to probe perception of poorly attended contour-defined or motion-defined loops while attention was occupied with congruent or incongruent feature detec...
متن کاملFeature-based attention spreads preferentially in an object-specific manner
We studied the spreading of feature-based attention from attended to ignored motion fields (linear, circular, and combinations). When observers attended one of two superimposed motion fields on one side of the visual midline, sub-threshold priming by an ignored motion field was altered significantly on the opposite side of the midline. This attentional spreading was observed only when attended ...
متن کاملModulation of spatial Stroop by object-based attention but not by space-based attention.
Earlier studies have shown that the spatial Stroop effect systematically decreases when a peripheral precue is presented at the same location as the target, compared to an uncued location condition. In this study, two experiments were conducted to explore whether the cueing modulation of spatial Stroop is object based and/or space based. In Experiment 1, we found evidence favouring the view tha...
