Object-based attention: sensory modulation or priority setting?
The detection of an invalidly cued target is faster when it appears within a cued object than when it appears in an uncued object equally distant from the cued location; this is a manifestation of object based attention. Five experiments are reported in which it was investigated whether early sensory enhancement (in which attention "spreads" within an attended object but stops at its borders) o...
متن کاملObject-based attention: sensory enhancement or scanning prioritization.
The three experiments reported here test whether object-modulated attentional spreading can be obtained when the target location is 100% certain. Experiment 1 uses the reaction time (RT)-based flanker task similar to Shomstein and Yantis (2002), and replicates the null result of the object-modulated attentional spreading. RT and accuracy (ACC) have been shown to reflect different processes: pos...
متن کاملEvidence-based priority setting.
This paper describes evidence-based priority setting and resource allocation undertaken by a Division of the Women's & Children's Hospital, Adelaide during 1998-1999. We describe the methods used to combine program budgeting marginal analysis (PBMA), evidence based and "community values" approaches into one decision-making framework. Previous organisational changes involving the formation of mu...
متن کاملObject-based attention: shifting or uncertainty?
The contribution of object-based attentional guidance to visual processing is widely accepted, and recent models of attentional selection now include both space- and object-based representations. Nevertheless, although the mechanism of space-based attentional selection has been well characterized, the mechanism underlying object-based attentional selection remains poorly understood. Recent atte...
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...
