本研究比较了在不同提示条件下视觉旋转的单适应和双适应。参与者适应恒定旋转或以交替顺序应用的相反旋转（双重适应）。在实验1中，视觉和相应的姿势线索，以指示不同的旋转方向。在实验2中，无论是视觉或姿势线索。在所有的提示条件下，大量的双重适应观察到，虽然它是衰减相比，单一的适应。转换成本的分析确定为性能之间的差异，最后一次审判之前和第一次审判后，旋转方向的变化建议实质性优势的视觉线索相比，姿势的线索，这是符合以往的研究结果表明，视觉的优势在运动的代表性和控制。
The present study compared single and dual adaptation to visuomotor rotations in different cueing conditions. Participants adapted either to a constant rotation or to opposing rotations (dual adaptation) applied in an alternating order. In Experiment 1, visual and corresponding postural cues were provided to indicate different rotation directions. In Experiment 2, either a visual or a postural cue was available. In all cueing conditions, substantial dual adaptation was observed, although it was attenuated in comparison to single adaptation. Analysis of switching costs determined as the performance difference between the last trial before and the first trial after the change of rotation direction suggested substantial advantage of the visual cue compared to the postural cue, which was in line with previous findings demonstrating the dominance of visual sense in movement representation and control.
