辨别本体感受和视觉空间信息是学习视觉运动转换的先决条件。本研究探讨了个体在视觉-运动旋转范式下辨别所见光标运动和所感手部运动方向的能力及其年龄相关变化。年轻和年长的参与者在数字化平板电脑上进行了3次手臂动作，而看不到他们的手臂。第二次动作的视觉反馈随机旋转了-30 °到30°的各种角度，并显示在监视器上。老年人比年轻人更容易受到歧视。在这两个年龄组中，感觉到的手的方向朝着看到的光标方向移动（即，视觉捕获）通过视觉反馈的旋转的大约25%到30%。老年人也表现出增强的视觉捕捉。结果表明，增加的感觉噪声和增加的双峰信息的同化导致老年人的辨别能力下降。这些发现提供了与年龄相关的变化在学习新的视觉运动转换的根本原因。
Discrimination of proprioceptive and visual spatial information is a prerequisite for the learning of visuo-motor transformations. This study investigated the individual's capability to discriminate the directions of seen cursor motions and felt hand movements under a visuo-motor rotation paradigm and its age-related variation. Young and older participants performed 3-stroke arm movements on a digitizing tablet without seeing their arm. The visual feedback of the second stroke was rotated randomly by various angles ranging from −30° to 30° and displayed on a monitor. Older adults were poorer in discrimination than young adults. In both age groups, the felt hand direction was shifted toward the seen cursor direction (i.e., visual capture) by approximately 25% to 30% of the rotation of the visual feedback. Older adults also showed an enhanced visual capture. The results suggest that both the increased sensory noise and the increased assimilation of the bimodal information cause the reduction of discrimination capability in older adults. These findings provide underlying reasons for age-related changes in learning a new visuo-motor transformation.
