注意力的转移会导致视觉对象定位错误。一个吸引注意力的简短提示可以导致对随后呈现的视觉对象的感知位置发生变化——具体来说，就是将其从注意力焦点移开（注意力排斥）。在本研究中，我们探讨了深度是否会通过在不同深度平面上呈现来自目标或注视的周边视觉线索来影响注意排斥的程度。实验1的结果表明，当提示出现在距离目标和注视点较远的深度平面时，注意排斥的幅度较大。在实验2中，我们将注视点与最近的线索呈现在同一深度平面上，发现当线索呈现在远离注视点的深度平面上时，斥力效应更大。在实验3中，当注视与最远的线索呈现在同一深度平面时，没有观察到深度调制。综上所述，当线索出现在距离注视点较远的深度平面时，注意排斥效应的强度增加。我们推测，在远离注视平面的空间中残留的更粗糙的空间表征或在比注视平面更近的空间中增强的注意过程可能是引起更大的注意排斥效应的原因。
Shifts of attention can cause mislocalisation of visual objects. A brief cue that attracts attention can cause a shift in the perceived location of a subsequently presented visual object—specifically, moving it away from the focus of attention (attentional repulsion). In the present study we investigated whether depth would influence the magnitude of attentional repulsion by presenting peripheral visual cues in different depth planes from the target or fixation. In experiment 1 the results showed that the magnitude of the attentional repulsion was larger when the cue was presented at the depth plane farther away from the target and fixation. In experiment 2 we presented the fixation point in the same depth plane as the nearest cues and found larger repulsion effects when the cues were presented in depth planes farther away from the fixation. In experiment 3 no depth modulation was observed when the fixation was presented in the same depth plane with the farthest cues. Taken together, when the cues were presented in the depth plane farther away from the fixation, the magnitude of the attentional repulsion effect increased. It is speculated that the residual coarser spatial representation in the space farther from the fixation plane or the enhanced attentional process for the space closer than the fixation may be responsible for the larger attentional repulsion effect.
