Abstract

Inhibition of return is the effect due to which it takes a longer time for people to attend recently examined locations. In a typical inhibition of return paradigm, a peripheral location was exogenously cued, following which attention was disengaged from the cued location. Thereafter, return to the cued location was inhibited. Although attentional disengagement from the cued location was a critical component in inhibition of return, the effect of a fixation cue following the peripheral cue on eliciting exogenously triggered attentional  disengagement was not fully tested. The present study examined the effect of this fixation cue, while endogenous attentional disengagement was varied across the experiments. It was demonstrated that the fixation cue, or exogenously triggered attentional disengagement from the cued location, was critical to inhibition of return only in the absence of endogenous attentional disengagement from the cued location.

Keywords: attentional disengagement, fixation cue, inhibition of return
