It has been suggested that the human visual system exploits an adaptable metric to implement a precise but plastic spatial representation. Indeed, adapting to a dense dot-texture reduces the apparent separation of subsequently presented dots pairs. Whether this metric is purely visual or shared between senses is still unknown. Here we present a new cross-modal after-effect revealing that the metric with which the visual system computes the relative spatial position of objects is shared with the motor system. A few seconds of mid-air self-produced tapping movements (adaptation) yielded a robust compression of the apparent separation of dot pairs subsequently displayed around the tapping region. This visuo-motor spatial metric could reflect an efficient functional architecture to program and execute actions aimed at efficient interaction with the objects in the environment.

运动适应扭曲了视觉空间。


有人建议，人类视觉系统利用适应性度量来实现精确但可塑的空间表示。事实上，适应密集的点纹理会减少随后呈现的点对的明显分离。该指标是纯粹的视觉指标还是感官之间共享的指标仍然未知。在这里，我们提出了一种新的跨模态后效应，揭示了视觉系统计算物体相对空间位置的度量与运动系统共享。几秒钟的空中自产生的敲击运动（适应）对随后在敲击区域周围显示的点对的明显分离产生了强烈的压缩。这种视觉运动空间度量可以反映一种有效的功能架构，用于编程和执行旨在与环境中的物体进行有效交互的动作。
