Preview of partial stimulus information in search prioritizes features and conjunctions, not locations.

Color selection efficacy As in Experiment 1 , CSE declined following a gray-bar preview, F (2, 8) = 10.74, p = .006, η p 2 = .73, whereas the two disc and color-bar previews had only small effects on CSE that did not reach statistical significance—color-bar: F (2, 8) = 3.3, p = .10, η p 2 = .45; color-disc: F (2, 8) = 1.6, p = .27, η p 2 = .29; gray-disc: F (2, 8) = 1.6, p = .27, η p 2 = .29.
