线框（内克尔）立方体的旋转方向，这是感知的，可以训练依赖于刺激位置。然而，目前还不知道“位置”的哪些方面对这种学习很重要。因此，我们在一系列实验中探索了“位置”，这些实验分别评估了测试地点、相对于观察者的位置以及视网膜图像中的位置，作为可能被视觉系统招募的位置信号类型。受试者使用线框立方体进行训练，旋转方向由深度线索消除歧义。训练立方体呈现在两个位置，以相反的方向旋转。在交错测试试验中，模糊的单眼立方体出现在相同的两个位置。在何种程度上，测试立方体被认为是旋转根据训练的位置旋转权变是我们的测量位置线索招聘。我们发现，只有视网膜的位置被招募作为一个线索，明显的旋转方向。此外，学习的视网膜位置线索是强大的眼转移。我们的研究结果与一个相对较低水平的学习网站，如MT一致。
The direction of rotation of a wire-frame (Necker) cube, which is perceptually bistable, can be trained to depend on stimulus location. However, it is not known which aspects of “location” are important to this learning. We therefore explored “location” in a series of experiments that separately assessed testing venue, location relative to the observer, and location in the retinal image as types of location signal that could potentially be recruited by the visual system. Subjects were trained using wire-frame cubes with rotation direction disambiguated by depth cues. Training cubes were presented at two locations, rotating in opposite directions. On interleaved test trials, ambiguous monocular cubes were presented at the same two locations. The extent to which test cubes were perceived to rotate according to the trained location-rotation contingency was our measure of location-cue recruitment. We found that only retinal position was recruited as a cue for apparent rotation direction. Furthermore, the learned retinal location cue was robust to ocular transfer. Our findings are consistent with a relatively low-level site of learning, such as MT.
