Abstract
Do salient distractors have the power to automatically capture attention? This question has led to a heated debate concerning the role of salience in attentional control. A potential resolution, called the signal suppression hypothesis, has proposed that salient items produce a bottom-up signal that vies for attention, but that salient stimuli can be suppressed via top-down control to prevent the capture of attention. This hypothesis, however, has been criticized on the grounds that the distractors used in initial studies of support were weakly salient. It has been difficult to know how seriously to take this low-salience criticism because assertions about high and low salience were made in the absence of a common (or any) measure of salience. The current study used a recently developed psychophysical technique to compare the salience of distractors from two previous studies at the center of this debate. Surprisingly, we found that the original stimuli criticized as having low salience were, if anything, more salient than stimuli from the later studies that purported to increase salience. Follow-up experiments determined exactly why the original stimuli were more salient and tested whether further improving salience could cause attentional capture as predicted by the low-salience account. Ultimately, these findings challenge purely stimulus-driven accounts of attentional control. (PsycInfo Database Record (c) 2024 APA, all rights reserved).
