A solid (ie filled-in) two-dimensional form is seen in motion toward another solid object of different shape and not towards an outline object of the same shape. The interpretation of these findings in terms of luminance-domain spatial frequency filtering is challenged by experiments in which the same results were obtained with kinetic and cyclopean forms.
一个实心（即填充）的二维图形朝着另一个形状不同的实心物体移动，而不是朝着相同形状的轮廓物体移动。用亮度域空间频率滤波来解释这些发现受到了一些实验的挑战，在这些实验中，使用动态和双眼视觉图形也获得了相同的结果。
