Abstract

This article examines whether defining features can also determine inhibition when participants are required to make a cognitive search on the basis of a target feature (color or shape). In 2 spatial localization experiments in which a touch-sensitive monitor was used, results indicated that distractor inhibition depended on both defining and reported stimulus features. Two additional experiments examined the locus of discrepancy between these results and other findings (e.g., B. Milliken, S. R Tipper, & B. Weaver, see record 1994-35938-001). The researchers concluded that defining features can determine inhibition in a selective attention task involving spatial localization. However, defining-feature inhibition may depend on level of analysis of the stimuli.
