Inhibition of return promotes stop‐signal inhibition by delaying responses
Abstract:Inhibition of return (IOR) refers to a mechanism that slows response times (RTs) to detect, localize, or discriminate a target that is presented at a location previously occupied by an irrelevant peripheral cue. Generally, the slowing of RTs is described as a negative effect on responding that is believed to promote searching to new locations. In this report, we consider whether IOR might benefit performance when the goal is to prevent a prepared response. Using the stop-signal paradigm, we show that IOR improved the ability to inhibit a prepared response by delaying responses to the target. Thus, in addition to aiding visual search, IOR may also provide an opportunity for the adjustment of decisions and behaviour in accordance with the demands of a dynamic environment.
