Previous research on visuospatial attention has shown that peripheral abrupt-onset cues at target position (valid condition) lead to faster reaction times than cues indicating a different position (invalid condition). When using late stimulus onset asynchronies (SOA) above 300 ms this so called cueing effect is reversed and inhibiton of return (IOR) follows with delayed reaction times in the valid condition. More recently, IOR was found in conditions with unconsciously perceived cues as well

In the present study, the effects of IOR were investigated by comparing the reaction times of irrelevant supraliminal and subliminal cues for each a short (16 ms) and a long (1000 ms) SOA with targets more often (75 %) presented at the opposite position of the cue (antipredictive). Therefore the paradigm of Mulckhuyse and colleagues (2007) was adopted by using their technique of flicker fusion for the unconscious condition. The results rule out the idea of IOR as an automatic process and, hence, speak for a controlled mechanism underlying the effect.
