COLOR PRIMING AND ADAPTATION IN COLOR-SINGLETON SEARCH Brian A. Goolsby and Satoru Suzuki, Department of Psychology, Northwestern University, Evanston, IL, U.S.A. Previously, we showed that repetition of a target-distractor color relationship in a color-singleton search task facilitates allocation of attention to subsequent singleton targets (Psychonomics, 1999; 2000). Here, we investigated the conditions for which color-singleton search is also facilitated through distractor-color adaptation. RT was reduced when the distractor color on a color-singleton trial was repeated from a previous trial where all items were the same-color. A large central distractor-colored patch did not similarly facilitate later singleton detection. The adaptation items and color-singleton items did not need to share position, eccentricity, or shape. These results suggest that the color representation underlying this distractor-adaptation effect is specific to discrete items, but not to position and shape.
