The Effect Of Spatial Location On Distribution Of Inhibition Of Return In Multiple Cues

Inhibition of Return(IOR)is of great significance to human life.It can improve the efficiency of visual search.Since Posner discovered the phenomenon,many researchers have conducted in-depth research on its spatial mechanism.They found that under the condition of multiple cues,the spatial distribution of IOR would be affected by the global effect.However,they did not consider the influence of spatial location sensitivity of cues on the global effect.Therefore,this study designed two experiments to explore the effect of cue's position sensitivity on the spatial distribution pattern of IOR under multi-cues.In Experiment 1,the influence of the change of the spatial orientation of the multi-cue stimulus on the spatial distribution of IOR.It was found that both the single cue and the multi-cue found IOR;and,under the single cue,the spatial distance effect was also found.When the spatial distance between the target and the cue is longer,the IOR effect is weaker.While under the multi-cue,when the target and the clue position are consistent,no spatial distance effect is found;under the multi-cue,when the target and the cues position,when inconsistent,the spatial distance effect was found.The above results indicate that,after adjusting the position of the cues,the spatial distribution of IOR has changed.Experiment 2 investigated the effect of cues position sensitivity on the spatial distribution of IOR by controlling the spatial sensitivity of cue position.It was found that the effect of IOR can be observed under the prompt of multiple cues;and the spatial sensitivity of the cues does not affect the spatial distribution of IOR.However,in Experiment 2,when the SOA is 800ms,the sensitivity of the cue position will affect the IOR.Under the condition of inconsistent cue sensitivity,the high sensitivity position has a stronger IOR than the low sensitivity position;Under the same cue sensitivity,there is no difference in the IOR effect between the high sensitivity position and the low sensitivity position.The results of this experiment show that the sensitivity of multiple cue locations will affect the spatial distribution of IOR,but will be limited by SOA.The general conclusions of this study are as follows:(1)The phenomenon of IOR can be observed under multi-cues;(2)When the SOA is long,the spatial distribution pattern of IOR under multi-cues is affected by the spatial orientation of the cues.
