Attention, segregation, and textons: Bridging the gap between object-based attention and texton-based segregation

Attention, segregation, and textons: Bridging the gap between object-based attention and texton-based segregation

Studies of object-based attention (OBA) have suggested that attentional selection is intimately associated with discrete objects. However, the relationship of this association to the basic visual features ('textons') which guide the segregation of visual scenes into 'objects' remains largely unexplored. Here we study this hypothesized relationship for one of the most conspicuous features of ear...

Bridging the Gap Between Object-Based Attention and Texton-Based Segmentation: How Attention Spreads Through Orientation-Defined Textures

Many recent studies of object-based attention (OBA) have suggested that the underlying units of attention are often discrete objects, through which attention readily spreads. However, the relationship of such experiments to the basic visual features (‘textons’) which guide the segmentation of visual scenes into ‘objects’ remains largely unexplored. Here we bridge this gap for one of the most co...

Toward a Biased Competition Account of Object-Based Segregation and Attention

Because the visual system cannot process all of the objects, colors, and features present in a visual scene, visual attention allows some visual stimuli to be selected and processed over others. Most research on visual attention has focused on spatial or location-based attention, in which the locations occupied by stimuli are selected for further processing. Recent research, however, has demons...

Interference between object-based attention and object-based memory.

Research has shown that there are at least two kinds of visual selective attention: location based and object based. In the present study, we sought to determine the locus of spatially invariant object-based selection using a dual-task paradigm. In four experiments, observers performed an attention task (object feature report or visual search) with a concurrent memory task (object memory or spa...
