The characteristics of the structural components inducing a length distortion were studied in Mueller-Lyer configuration and in other similar or different configurations. When placed in a more central position both ingoing and outgoing fins induced an apparent shrinkage of the shaft. It was found that a comparable effect is obtained as well with perpendicular lines and various other forms placed slightly centrally from the ends of the shaft (when placed away from the ends, an elongation is obtained). The shrinkage effect depended primarily on the ratio of the inner extent defined by the inducing forms to the extent of the shaft. With perpendicular inducing lines the most pronounced effects were observed at ratios of about 3/4. Configurations containing instead of perpendicular lines angled fins in equivalent positions showed a slightly more pronounced effect for the ingoing fins and less pronounced for the outgoing fins with a shift of optimal positions towards the ends for the ingoing and towards the center for the outgoing fins. If the ends of the shaft are marked by vertical lines the effect of the inducing forms is drastically reduced; it becomes significant as they exceed in vertical extent the end vertical lines. The findings support the idea of an interaction between size detectors as a basis of the length distorsion associated to Mueller-Lyer and other related configurations.
在穆勒-莱尔图形以及其他相似或不同的图形中，研究了导致长度变形的结构组件的特征。当置于更中心的位置时，无论是进入的鳍状物还是出去的鳍状物都会使杆体出现明显的收缩。研究发现，当垂直线条以及其他各种形式稍微位于杆体两端的中心位置时（当远离两端放置时，则会出现伸长），也会获得类似的效果。收缩效果主要取决于由诱导形式所界定的内部范围与杆体范围的比例。对于垂直线条，在比例约为3/4时观察到最明显的效果。在等效位置包含成角度的鳍状物而非垂直线条的图形中，对于进入的鳍状物效果略显明显，而对于出去的鳍状物效果则不太明显，且最佳位置向内移至进入鳍状物的端部，向外移至出去鳍状物的中心。如果杆体的端部由垂直线条标记，则诱导形式的效果会大幅降低；当它们在垂直范围上超过端部垂直线条时，效果才会变得显著。这些发现支持了尺寸探测器之间相互作用的观点，这是与穆勒-莱尔图形及其他相关图形相关的长度变形的基础。
