为了阐明预测接触时间的机制，我们对视觉和触觉刺激时间变化的适应过程进行了研究。在我们的实验中，视觉刺激是一个虚拟的球以9.8 m/s（2）的速度落下，任何触觉刺激都是如此。触觉刺激相对于视觉刺激移位-60、0和+60 ms。结果表明，受试者并没有意识到时间的变化，但仍然改变了他们的触觉反应的时间。还发现这种适应性改变导致受试者对视觉触觉灵敏度的判断发生约60 ms的变化。（C）2011 Elsevier B. V.保留所有权利。
In order to elucidate the mechanism for predicting timing of contact, we performed an investigation of the adaptation process for shifts in the timing of visual and tactile stimuli. In our experiments, the visual stimulus was a virtual ball falling at 9.8 m/s(2) for any tactile stimulus. Tactile stimuli were shifted by -60, 0 and +60 ms, relative to the visual stimulus. Results showed that the subjects were not aware of the timing shifts, but still changed the timing of their tactile responses. This adaptation was also found to cause a shift in the subjects' judgment of visuotactile simultaneity by approximately 60 ms. (C) 2011 Elsevier B.V. All rights reserved.
