Visual Marking and Change Blindness: Moving Occluders and Transient Masks Neutralize Shape Changes to Ignored Objects
Watson, Derrick G.; Kunar, Melina A.
Journal of Experimental Psychology: Human Perception and Performance, v36 n6 p1391-1405 Dec 2010
Visual search efficiency improves by presenting (previewing) one set of distractors before the target and remaining distractor items (D. G. Watson & G. W. Humphreys, 1997). Previous work has shown that this preview benefit is abolished if the old items change their shape when the new items are added (e.g., D. G. Watson & G. W. Humphreys, 2002). Here we present 5 experiments that examined whether such object changes are still effective in recapturing attention if the changes occur while the previewed objects are occluded or masked. Overall, the findings suggest that masking transients are effective in preventing both object changes and the presentation of new objects from capturing attention in time-based visual search conditions. The findings are discussed in relation to theories of change blindness, new object capture, and the ecological properties of time-based visual selection. (Contains 2 tables and 10 figures.)
