In four experiments involving blindfolded subjects, constant errors in the haptic judgment of extent in the horizontal plane were found to relate consistently to the time and velocity of limb movement. Radial movements, executed at a slower speed and for a longer time, are judged longer than tangential movements of equal extent. The data were considered in relation to certain physiological and kinematic properties of the actively moving limb. Taken together with additional information on judgments of movement duration, the results suggest that the illusion of extent is modulated by the perception of differential time cues. In these terms, it was noted that the haptic horizontal-vertical illusion with the L figure is another instance of the interaction of apparent space and time commonly found in studies of psychological relativity.
在四项针对蒙眼受试者的实验中，发现受试者在水平面内对范围进行触觉判断时的恒定误差始终与肢体运动的时间和速度相关。以较慢速度且较长时间执行的径向运动，相比同等范围的切向运动，会被判断为更长。这些数据是结合主动运动肢体的某些生理和运动学特性来考虑的。结合关于运动持续时间判断的其他信息来看，结果表明范围错觉是由对不同时间线索的感知所调节的。就此而言，有人指出带有L形的触觉水平 - 垂直错觉是心理相对论研究中常见的表观空间与时间相互作用的另一个实例。
