Subjective expectancy and inhibition of return: A dissociation in a non-spatial two-alternative forced choice task

Inhibition of Return (IOR) is conventionally defined by slow responses to targets that appear at the same location as a prior attentional cue, relative to a condition in which targets appear at a different location from a prior attentional cue (Posner & Cohen, 1984). A number of recent studies have extended the study of IOR to non-spatial orienting tasks (Law, Pratt, & Abrams, 1995; Hu, Samuel, & Chan, 2011; Spadaro, He, & Milliken, 2012), …
