这项研究表明，在一项新颖的任务——双手触觉追踪中，神经正常的成年人可以在很少或没有训练的情况下独立地长时间移动他们的两只手。参与者轻轻地触摸按钮，这些按钮的位置在水平面上由1或2名人类驾驶员（实验1）准随机移动，在垂直平面上由2名人类驾驶员（实验2）以圆形和方形模式移动，或在水平面上由2名人类驾驶员以不同频率移动（实验3）。尽管在实验1中左右运动不相关（双驾驶员条件下），在实验2中同时跟踪圆形和正方形时，左右运动在空间上不协调，在实验3中左右运动保持不同的频率比，但在所有条件下，双手接触都保持得同样好。因为触觉追踪已经揭示了人类实际上可以独立移动两只手，它可能有潜力作为一种新的行为工具来揭示其他感知运动能力。
This study shows that in a novel task—bimanual haptic tracking—neurologically normal human adults can move their 2 hands independently for extended periods of time with little or no training. Participants lightly touched buttons whose positions were moved either quasi-randomly in the horizontal plane by 1 or 2 human drivers (Experiment 1), in circle and square patterns in the vertical plane by 2 human drivers (Experiment 2), or at different frequencies in the horizontal plane by 2 human drivers (Experiment 3). Bimanual contact was maintained equally well in all conditions even though in Experiment 1 the left-and right-hand motions were uncorrelated (in the 2-driver condition), in Experiment 2 the left-and right-hand motions were spatially incongruous when circles and squares were tracked at the same time, and in Experiment 3 the left-and right-hand motions maintained different frequency ratios. Because haptic tracking has revealed that humans can in fact move their 2 hands independently, it may have potential as a new behavioral tool for revealing other perceptual-motor capabilities.
