Object-based selection is contingent on attentional control settings.
The visual system allocates attention in object-based and location-based modes. However, the question of when attention selects objects and when it selects locations remains poorly understood. In this article, we present variations on two classic paradigms from the object-based attention literature, in which object-based effects are observed only when the object feature matches the task goal of...
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 کاملCortical mechanisms of space-based and object-based attentional control.
Visual attention, the mechanism by which observers select relevant or important information from scenes, can be deployed to locations in space or to spatially invariant object representations. Studies have examined both the modulatory effects of attention on the strength of extrastriate cortical representations, and the control of attention by parietal and frontal cortical circuits. Subregions ...
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 کاملObject-based attentional selection can modulate the Stroop effect.
The Stroop (1935) effect is the inability to ignore a color word when the task is to report the ink color of that word (i.e., to say "green" to the word RED in green ink). The present study investigated whether object-based processing contributes to the Stroop effect. According to this view, observers are unable to ignore irrelevant features of an attended object (Kahneman & Henik, 1981). In th...
