“…Recently, IOR has emerged as a useful phenomenon to explore influence of peripheral cue content on exogenous control of covert attention (e.g., Fox, Russo, & Dutton, 2002;Stoyanova, Pratt, & Anderson, 2007;Taylor & Therrien, 2005;Theeuwes & Van der Stigchel, 2006). First discovered and investigated by Posner and Cohen (1984; see Klein, 2000, for a review), IOR refers to the finding that, after attention has been exogenously cued and then withdrawn from a location, attention is biased against returning to the region, indicated by inhibited processing of stimuli at (or near) the previously attended location relative to previously unattended locations.…”
