An explanation of the Poggendorff misalignment illusion in terms of three basic components, the horizontal-vertical, longitudinal-transverse and obtuse angle effects, is proposed. It is argued that these effects amy either singly or jointly give rise to an apparent elongation- contraction of the space between the aligned elements with consequent change in apparent oblique direction. Experimental evidence for the involvement of the three components in various combinations and for modification of perceived direction between the transversals is presented. It is shown that the illusion in various forms of the Poggendorff figure can be accounted for by the involvement of one or more of the three components, each of which can be demonstrated independently of the illusion. It is suggested that other classical illusions, including the Müller-Lyer, might also be analysed in terms of basic components.
本文提出了一种基于三个基本成分，即水平-垂直、纵向-横向和钝角效应，对波根多夫错视进行的解释。文中认为，这些效应可能单独或共同导致对齐元素之间空间的明显伸长或收缩，从而使视在倾斜方向发生变化。文中还给出了实验证据，证明这三个成分以各种组合形式参与其中，并对视在横向之间的方向感知产生了改变。结果表明，波根多夫图形各种形式的错觉都可以通过这三个成分中的一个或多个的参与来解释，每个成分都可以独立于错觉进行演示。文中还提出，包括缪勒-莱尔错觉在内的其他经典错觉，也可能可以根据基本成分进行分析。
