The Effects of the Fixation Cue in Inhibition of Return

Abstract

In experiments examining inhibition of return (IOR), an attentional effect that inhibits the returning of attention to a previously attended location or object, a second cue during the stimulus onset asynchrony (SOA) period is typically used. This is done to control the reorienting of attention from a peripherally cued location back to the central fixation point before the target appears. Recently, there have been numerous studies which demonstrate that fixation cues are effective in revealing IOR. Plenty of factors have been shown to influence the effects of the fixation cue in IOR, including the time onset of the fixation cue, the number of potential target locations, the attentional demands of performing the task, the modality of the fixation cue, and the condition of participants. Here, the authors review previous work that has examined the effects of the fixation cue in IOR.
