Perception of local properties of the visual field is influenced by aftereffects of adaptation. The tilt aftereffect describes repulsion of the perceived orientation of a line from the orientation of an adapting line. Analogous effects of spatial context are often called illusions. Repulsion of the perceived orientation of a grating from the orientation of a surrounding grating is referred to as the tilt illusion. In the same manner, the size aftereffect and Ebbinghaus illusion form a complementary pair of temporal and spatial context effects of size. Here we report psychophysical evidence for a previously unknown aspect-ratio illusion which causes the perceived aspect-ratio of a rectangle to be repelled from the aspect-ratio of rectangles surrounding it. This illusion provides a spatial analogue to the aspect-ratio aftereffect.
人对视野局部的感知会受到适应后效的影响。倾斜后效描述了人感知到的线的方向会偏离适应线的方向。类似的空间背景效应通常被称为错觉。光栅的感知方向会偏离周围光栅的方向，这种现象被称为倾斜错觉。同样，大小后效和艾宾浩斯错觉形成了一对大小的时间和空间背景效应。在这里，我们报告了一个之前未知的纵横比错觉的心理物理证据，该错觉导致人感知到的矩形的纵横比与其周围矩形的纵横比产生偏离。这个错觉为纵横比后效提供了一个空间上的类似物。
