According to a growing number of studies, the stereographic presentation of three-dimensional information improves overall performance relative to displays with only monocular depth cues. Based on studies using real-world, three-dimensional stimuli, however, the efficiency (i.e., speed) of shifting attention between objects located at different depths is impaired relative to that of attention shifts between objects located at the same depth. In the present study we tested whether similar impairments occur when attention is shifted in stereographic space. We compared the time course of attention shifts across and within depth planes using a spatial cuing task. Contrary to the results from studies of real-world stimuli, we found no difference between the time course of within-plane and across-plane attention shifts.
越来越多的研究表明，相对于仅具有单眼深度线索的显示器，三维信息的立体呈现可提高整体性能。然而，基于使用真实世界三维刺激的研究，与在相同深度的物体之间转移注意力相比，在不同深度的物体之间转移注意力的效率（即速度）会受到损害。在本研究中，我们测试了在立体空间中转移注意力时是否会出现类似的损害。我们使用空间线索任务比较了跨深度平面和深度平面内注意力转移的时间进程。与对真实世界刺激的研究结果相反，我们发现平面内和跨平面注意力转移的时间进程没有差异。
