Discuss the practical implications of the research on Inhibition of Return Inhibition of Return (IOR) is the name given to the phenomena noted by Posner (1980) and Posner and Cohen (1984). IOR may be elicited by a central or peripheral precue that is predictive of a target location. Usually, a precue will facilitate responses when the cue is valid. However, in conditions where the delay between the cue and the target onset exceeds 300ms, the effect of early facilitation is lost, and the reaction time (RT) to cued locations increases to exceed the RT for targets appearing in uncued locations. The simple Posner and Cohen paradigm (1984) used three square boxes on a screen (fig. 1). FIG. 1: Experimental display for Posner & Cohen (1984) The middle box (A) was for fixation, and the experiment used uninformative peripheral cueing (150ms duration change in luminance) in the boxes on either side (B, C)...
