In everyday life, we solve such perceptual-cognitive bottlenecks by reducing the complexity of such a task via aligning parts with same lengths; actually, what Figure 1(f) and (l) provides is a kind of geometrical fractional arithmetic as one side of the first object fully cancels out one side of the second—to be compared—object. This reduces the degrees of freedom to just one—now only one remaining side has to be compared with the other side, and this works out brilliantly as shown by data provided in Figure 1 (for versions 1(f) and (l)). If we follow such a strategy to reduce the complexity of this perceptual task, we are able to validly estimate “area sizes”—in fact we are then only estimating unidimensional information—if we do not follow such a strategy, we evidently and substantially fail. The most important insight from the entire story seems to be: sometimes, insights from perceptual illusions are much more striking than even mathematical proof, particularly if such illusions show a high degree of Prägnanz! Finally, the enjoyment of perceiving such an emerging Gestalt and the insight it creates gives us the pleasure needed to continue in our path of perceptual learning (Muth & Carbon, 2013).
