Abstract

Visual search for a target is faster when its features are known before the search display appears, but there is an ongoing discussion about whether knowledge of nontarget features has a similar effect. Stored target or nontarget features used to guide visual search are referred to as positive or negative attentional templates, respectively. We suggest that the inconsistent findings concerning negative attentional templates may arise from 2 methodological choices in past research. The activation of negative attentional templates was never directly assessed and the use of negative attentional templates by the participant was optional. We addressed these issues in the contingent capture paradigm, which provides a marker for the activation of attentional templates in conditions where attentional templates are optional or mandatory. If an attentional template for a color is activated, cuing effects are larger for spatial cues in a matching color than for spatial cues in a nonmatching color. The question is whether the activation of negative attentional templates results in a similar difference between matching and nonmatching colors. We found that negative attentional templates were not activated when the target could be located based on its saliency (singleton search) and the use of the negative attentional template was optional. In contrast, when the negative attentional template was necessary to locate the target (feature search), we found the expected difference between matching and nonmatching spatial cues. Thus, the activation of negative attentional templates depends on task demands. In contrast, positive attentional templates were activated irrespective of task demands.
