Abstract: | There is an ongoing debate as to whether prioritizing new objects over old objects (the so-calledpreview benefit) is the result of top-down inhibition of old objects (i.e., visual marking; Watson & Humphreys, 1997) or attentional allocation
to new objects, presented with a luminance transient (Donk & Theeuwes, 2001). In the two experiments reported here, we tested
whether prioritization by luminance transients alone can produce a subset-selective search similar to the preview effect.
Subjects viewed multiobject displays while a subset of objects was briefly flashed. The subjects prioritized up to 14 flashed
objects over at least 14 nonflashed objects. Since prioritization by luminance transients can produce a subsetselective search
on its own, it may well play an important role in the preview benefit. |
