Tilt aftereffects induced by line gratings are maximal when the test and inducing stimuli have an angular separation of 10 degrees-15 degrees. Similar effects induced by prismatically tilted real-object scenes have been found to increase monotonically with scene tilt. The difference between these two angular functions of aftereffect (that induced by gratings and that induced by real objects) has been attributed to the 'meaning' inherent in the real-object scenes. The preliminary experiments described here suggest that tilt aftereffects and illusions induced by projected slides of tilted real-object scenes have angular functions similar to that induced by a line grating. Hence, the monotonically increasing angular function obtained in the prism studies is not necessarily determined by the use of real-object scenes.
当测试刺激与诱导刺激的角度间隔为10度至15度时，线光栅诱发的倾斜后效最大。已发现由棱镜倾斜的真实物体场景诱发的类似效应会随着场景倾斜而单调增加。后效的这两种角度函数（由光栅诱发的和由真实物体诱发的）之间的差异归因于真实物体场景中固有的“意义”。此处描述的初步实验表明，倾斜真实物体场景的投影幻灯片诱发的倾斜后效和错觉具有与线光栅诱发的类似的角度函数。因此，在棱镜研究中获得的单调增加的角度函数不一定由使用真实物体场景决定。
