Inhibition of return (IOR) is a phenomenon that reflects slower target detection when the target appears at a previously cued rather than uncued location. In the present study, we investigated the extent to which IOR occurs in three-dimensional (3D) scenes comprising pictorial depth information. Peripheral cues and targets appeared on top of 3D rectangular boxes placed on the surface of a textured ground plane in virtual space. When the target appeared at a farther location than the cue, the magnitude of the IOR effect in the 3D condition remained similar to the values found in the two-dimensional (2D) control condition (IOR was depth-blind). When the target appeared at a nearer location than the cue, the magnitude of the IOR effect was significantly attenuated (IOR was depth-specific). The present findings address inconsistencies in the literature on the effect of depth on IOR and support the notion that visuospatial attention exhibits a near-space advantage even in 3D scenes consisting entirely of pictorial depth information.
返回抑制（IOR）是一种现象，当目标出现在先前提示的位置而非未提示的位置时，反映出目标检测速度较慢。在本研究中，我们调查了IOR在包含图像深度信息的三维（3D）场景中出现的程度。外周提示和目标出现在虚拟空间中有纹理的地面平面上放置的3D矩形框顶部。当目标出现在比提示更远的位置时，3D条件下IOR效应的大小与二维（2D）对照条件下的值相似（IOR是深度盲的）。当目标出现在比提示更近的位置时，IOR效应的大小显著减弱（IOR是深度特定的）。本研究结果解决了关于深度对IOR影响的文献中的不一致之处，并支持了即使在完全由图像深度信息组成的3D场景中，视觉空间注意也表现出近空间优势的观点。
