Researchers have long debated the nature of cognitive control in vision, with the field being dominated by two theoretical camps. Stimulus-driven theories claim that visual attention is automatically captured by salient stimuli, whereas goal-driven theories argue that capture depends critically the goals of a viewer. To resolve this debate, we have previously provided key evidence for a new hybrid model called signal suppression hypothesis. According to this account, all salient stimuli generate an active salience signal which automatically attempts to guide visual attention. However, this signal can be actively suppressed. In the current talk, we review the converging evidence for this active suppression of salient items, using behavioral, eye tracking and electrophysiological methods. We will also discuss the cognitive mechanisms underlying suppression effects and directions for future research.
