The haptic horizontal-vertical illusion was studied in two experiments. In Experiment 1, the illusion was relatively weak in sighted subjects and depended on stimulus size and the nature of the figure, that is, whether the pattern was an inverted-T or L shape. Experiment 2 compared early blind and late blind subjects. The illusion was present for an inverted-T figure but absent for an L figure in late blind subjects. However, the early blind subjects treated both the L and T figures as similar and showed the illusion to both. These results support the idea that visual experience may alter haptic judgments in sighted and late blind subjects.
通过两个实验对触觉水平-垂直错觉进行了研究。在实验1中，有视觉的受试者的错觉相对较弱，且取决于刺激大小和图形的性质，即图案是倒T形还是L形。实验2比较了先天失明和后天失明的受试者。后天失明的受试者中，倒T形图形会产生错觉，而L形图形则不会。然而，先天失明的受试者认为L形和T形图形相似，对两者都会产生错觉。这些结果支持了这样一种观点，即视觉经验可能会改变有视觉的人和后天失明的受试者的触觉判断。
