我们刻画了一类时空错觉的两个互补性质。首先，如果游标刺激在监视器上闪烁一小段时间，然后立即出现光栅，后者可以表达游标的特征，如其偏移、方向或运动（特征继承）。然而，微调刺激本身在感知上仍然是不可见的。其次，游标可以通过呈现具有大量元件的光栅（透照）而变得可见。在这些条件下，受试者感知到两个独立的“对象”，每个对象都具有自己的特征，这两个域之间的过渡可以通过光栅的时空布局的细微变化来实现。这应该允许精神病学家和电生理学家以精确和定量的方式研究特征结合。
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.
