Attentional Spreading in Object-Based Attention
Richard, Ashleigh M.; Lee, Hyunkyu; Vecera, Shaun P.
Journal of Experimental Psychology: Human Perception and Performance, v34 n4 p842-853 Aug 2008
The authors investigated 2 effects of object-based attention: the spread of attention within an attended object and the prioritization of search across possible target locations within an attended object. Participants performed a flanker task in which the location of the task-relevant target was fixed and known to participants. A spreading attention account predicts that object-based attention will arise from the spread of attention through an attended object. A prioritization account predicts that there will be a small, if any, object-based effect because the location of the target is known in advance and objects are not required to prioritize the deployment of attentional search. The results suggested that object-based attention operates via the spread of attention within an object. (Contains 6 figures, 1 table, and 3 footnotes.)
