Inhibition of return at foveal and extrafoveal locations: re-assessing the evidence

Abstract

Inhibition of return (IOR) has been described as a hallmark of externally controlled orienting of attention using extrafoveal cues and targets. This paper describes an IOR like inhibition of reaction time for the detection of targets at the fovea that cannot be explained by shift of covert attention. This foveal RT inhibition adds to the evidence that challenges the view of IOR-like phenomena as obligatory expressions of orienting and attentional control.
