Inhibition of return
Inhibition of return ( IOR ; German for "inhibition of return") describes a phenomenon of gaze movement : If a test person observed an object at a certain location more closely (between 100 and 300 milliseconds), then it is very unlikely that after a change of focus ( so-called saccade ) looks there again, but instead looks at other areas that were not observed. It is therefore assumed that the function of the IOR is to gain as much information as possible and to discover new things.
The phenomenon was first described by Michael Posner and Yoav Cohen , who tried in vain to show that the response time when finding certain objects is less in the old position than in a new position. Cues at the same position before the object searched for can also trigger the IOR, but the cue must appear at least between 300 and 500 milliseconds beforehand. With a shorter time interval (100-300 milliseconds), however, the response time improves.
