摘　　要：利用虚拟现实技术,将IOR经典线索提示范式应用到三维空间,设置不同的深度距离,操纵目标深度、线索类型两个自变量,分析IOR效应的差异,并进一步探索其在三维空间中的扩散范围问题。结果发现:(1)短距离条件下,同侧视野不同深度的线索(Z-无效)反应显著慢于不同视野相同深度的线索(X-无效)反应,而长距离条件下,两者无显著差异;(2)无论目标深度远近,IOR效应均存在,短距离条件Z-无效的IOR量均显著小于长距离条件。结论:三维空间存在IOR,并在深度位置上具有一定的扩散范围,以提示线索位置为中心,IOR的扩散程度随深度距离的增加而降低。Inhibition of return(IOR),typically explored in cueing paradigms,is a performance cost associated with previously attended locations.It has been suggested as a crucial attentional mechanism that biases orientation towards novelty.Our living environment turns out to be a complex threedimensional space which entails ecological functioning of visual search.In Wang et al.’s(2015)three-dimensional experiment,participants’attention was(re)oriented in a straight line along the depth plane to induce location-based IOR.However,their operation could have an inconsistent depth distance,contaminating the IOR effect.Our study thus aimed to explore the range of IOR spreading in the depth of three-dimensional space.Two depth distances were manipulated in the study:short distance for Experiment 1 and short distance for Experiment 2.The types of cuetarget were divided into Valid(the target appeared in both the same depth plane and hemispace of the vision as the cue),X-Invalid(the target appeared in the same depth plane,but different hemispace of the vision as the cue),Z-Invalid(the target appeared in the same hemispace of the vision,but in different depth plane as the cue),and X-Z-Invalid(the target appeared in the different depth plane and hemispace of the vision).The cue-target in depth of target(closer depth plane vs.farther depth plane)was crossed with the cue-target types,forming a 2×4 factorial design in the two experiments.At the beginning of each trial,either of the four locations in the near or far space was cued for 300ms,and was followed by an interval of 200ms interstimulus.Then the spatial location of the central fixation cross was cued for 200ms to divert attention away from the previously by cued location.After another period of 150 or 250ms,the target was presented for 250ms at one of four locations,either cued or un-cued,with equal probability for four cue types.The validity of clues was 25%in the two experiments.Our results revealed a main effect of cue types in both the short,F(3,28)=13.914,p<.001,and long
