在三个实验中，两个独立的样本，12个观察员，每个人都目视检查修改后的版本的蒂琴纳的aSyen的T型接头已被删除。在实验1中，aSyenaEuro（TM）的两条线被不相交于一个公共点的虚线所取代;在实验2中，aSyen被减少为五个点，代表原始线的端点和中点;在实验3中（第二个观察者样本），aSyen被分成两条独立的线，彼此间隔不同。观察者用触觉指示修改后的aSyens的两条正交线的长度，并用口头判断它们的相对长度或相应点之间的距离。实验1和2中常见的知觉错觉持续存在，但实验3中明显减弱。从下而上的错觉神经生理学帐户的影响，与自上而下激活的图形图式的方向敏感的机制之间的长期相互作用的阐述。
In three experiments, two independent samples of 12 observers each visually inspected modified versions of Titchener's aSyen from which the T-junctions had been deleted. For Experiment 1, the aSyenaEuro (TM) s two lines had been replaced by dashed lines not meeting in a common point; for Experiment 2, the aSyen had been reduced to five dots, representing the original lines' end- and midpoints; and for Experiment 3 (in which the second sample of observers served), the aSyen had been dissected into two separate lines, differently spaced from each other. Observers haptically indicated the lengths of the two orthogonal lines of the modified aSyens and verbally judged their relative lengths or the distances between the corresponding dots. The common perceptual illusions persisted in Experiments 1 and 2, but were markedly weakened in Experiment 3. Implications for a neurophysiological account of the illusions in terms of bottom-up, long-range interactions between orientation-sensitive mechanisms versus top-down activation of a figural schema are spelled out.
