Object-based visual attention with endogenous orienting.
In a series of experiments, we examined covert orienting using endogenous cuing, in which attention is voluntarily directed toward a peripheral location. In one experiment, subjects were cued to attend to one end of an oblong object. They then detected targets on the cued object or elsewhere. In another experiment, subjects provided judgments of the relative temporal order of two flashes after ...
متن کاملCompetition between endogenous and exogenous orienting of visual attention.
The relation between reflexive and voluntary orienting of visual attention was investigated with 4 experiments: a simple detection task, a localization task, a saccade toward the target task, and a target identification task in which discrimination difficulty was manipulated. Endogenous and exogenous orienting cues were presented in each trial and their validity was manipulated orthogonally to ...
متن کاملModulation of object-based attention by spatial focus under endogenous and exogenous orienting.
In R. Egly, J. Driver, and R. D. Rafal's (1994) influential double-rectangle spatial-cuing paradigm, exogenous cues consistently induce object-based attention, whereas endogenous cues generally induce space-based attention. This difference suggests an interdependency between mode of orienting (endogenous vs exogenous) and mode of selection (object based vs space based). However, mode of orienti...
متن کاملEndogenous Orienting of Attention without Awareness
This study investigated the role of awareness in endogenous orienting of visual attention. Twenty-five subjects performed a Covert Attention Task, in which target stimuli were preceded by masked and unmasked symbolic central cues (i.e., digits). Results showed a facilitation effect in both the aware and unaware condition, suggesting that a symbolic cue was able to induce an endogenous orienting...
متن کاملObject-based attention with endogenous cuing and positional certainty.
Previous studies have concluded that object-based attention does not always arise if attention is cued endogenously (Macquistan, 1997) or if the target location is known with certainty (Shomstein & Yantis, 2002). In the Experiments reported here, we found object-based attention even when the locations of the two targets were known with certainty due to presentation of an endogenous cue. However...
