[Role of connectedness in early object-based attentional selection].
It has been suggested that uniform connectedness is the most fundamental factor in forming units of attentional selection, while there are evidences that attention can select a perceptual group that consists of separate elements with similar features. The present study examined the effects of connectedness and a boundary-feature similarity on early spatial-selection processes using a sustained-...
متن کاملObject-based selection: the role of attentional shifts.
The objective of this paper was to investigate under what conditions object-based effects are observed. Recently, Watson and Kramer (1999) used a divided-attention task and showed that unless top-down factors induce a bias toward selection at a higher level, object-based effects are obtained when same-object targets belong to the same uniformly connected (single-UC) region, but not when they be...
متن کاملStrategic effects on object-based attentional selection.
The same-object benefit, that is faster and/or more accurate performance when two target properties to be identified appear on one object than when each of the properties appear on different objects, has been a robust and theoretically important finding in the study of attentional selection. Indeed, the same-object benefit has been interpreted to suggest that attention can be used to select obj...
متن کاملNeural correlates of object-based attentional selection in human cortex.
Humans can attend to different objects independent of their spatial locations. While selecting an object has been shown to modulate object processing in high-level visual areas in occipitotemporal cortex, where/how behavioral importance (i.e., priority) for objects is represented is unknown. Here we examined the patterns of distributed neural activity during an object-based selection task. We m...
متن کاملThe role of visual short-term memory in object-based attentional selection
The present study investigated the relationship between object-based attention and visual short-term memory (VSTM). Three claims were investigated: (a) spatial attention and spatial STM share similar processing resources; (b) object-based attention and object STM share similar processing resources; and (c) both sets of processing resources are dissociable. Although the first claim is well estab...
