We characterize a class of spatio-temporal illusions with two complementary properties. Firstly, if a vernier stimulus is flashed for a short time on a monitor and is followed immediately by a grating, the latter can express features of the vernier, such as its offset, its orientation, or its motion (feature inheritance). Yet the vernier stimulus itself remains perceptually invisible. Secondly, the vernier can be rendered visible by presenting gratings with a larger number of elements (shine-through). Under these conditions, subjects perceive two independent "objects" each carrying their own features. Transition between these two domains can be effected by subtle changes in the spatio-temporal layout of the grating. This should allow psychophysicists and electrophysiologists to investigate feature binding in a precise and quantitative manner.
我们描述了一类具有两种互补特性的时空错觉。首先，如果一个游标刺激在显示器上短时间闪烁，然后紧接着呈现一个光栅，那么后者可以表现出游标的特征，比如其偏移量、方向或运动（特征继承）。然而，游标刺激本身在感知上仍然是不可见的。其次，通过呈现具有更多元素的光栅，可以使游标变得可见（穿透显示）。在这些条件下，受试者会感知到两个独立的“物体”，每个都带有自己的特征。这两个领域之间的转换可以通过光栅时空布局的细微变化来实现。这应该能让心理物理学家和电生理学家以精确和定量的方式研究特征捆绑。
