A subdivided path in the visual field appears longer than an empty path of the same length. This effect may be attributed to the division of the path into multiple segments, or to an influence of the visual elements used to mark the subdivision, and thus filling-up the estimated space. To address this question, we used two series of stimuli, in which the spatial distribution of the filling optical mater, or the form of the dividers, was varied while the relative coverage of the filled space was kept constant. We found significant dependence of the effect magnitude on a number of filling elements as well as on their form. These results indicate that the illusory space expansion is not merely an effect of 'filling-up' the space, but it also depends on the filling pattern. Consequences of these findings for the theory of the Oppel-Kundt phenomenon are briefly discussed.
视野中细分的路径看起来比相同长度的空白路径更长。这种效应可能归因于路径被分割成多个部分，或者归因于用于标记细分的视觉元素的影响，从而填充了估计的空间。为了解决这个问题，我们使用了两组刺激，其中填充光学材料的空间分布或分隔物的形式有所变化，而填充空间的相对覆盖率保持不变。我们发现效应大小显著依赖于填充元素的数量及其形式。这些结果表明，虚幻的空间扩展不仅仅是空间“填充”的效应，还取决于填充模式。简要讨论了这些发现对奥佩尔 - 昆特现象理论的影响。
