Top-down search for color prevents voluntary directing of attention to informative singleton cues
Ansorge, Ulrich and Worschech, Franziska (2012) Top-down search for color prevents voluntary directing of attention to informative singleton cues. Experimental Psychology 59 (3), pp. 153-162. ISSN 1618-3169.
Visuo-spatial attention can be directed in a top-down controlled way to search for color targets and it can be captured by color contrasts, regardless of color identity. Here we tested whether participants can both search for a particular color target (e.g., red) and make use of a color-contrast cue that predicted the target’s most likely position to direct their attention voluntarily. Our results show that this was impossible for the participants. Results support that top-down search for particular colors is incommensurate with directing attention to just any color contrast. The results are discussed in light of the current debates concerning the roles of color and color contrast for visuo-spatial attention.
