Summary:Gaspelin and Luck describe the signal suppression hypothesis, which proposes that attentional suppression prevents the capture of visual attention by salient distractors. We will discuss several problems with this proposal. On a theoretical level, we will argue that attentional suppression is a dispensable mechanism. Most effects of attentional suppression can be easily explained by reduced target expectancy at the distractor location. On an empirical level, we will argue that electrophysiological evidence for attentional suppression is spurious because, in key conditions, the P D most likely reflects idiosyncratic scan paths.
