Tests of proprioceptive adaptation (head-hand), visual adaptation (eye-head), and both components (eye-hand) were made during 15-min exposure to 20 degrees tilt in two experiments. In both experiments, subjects alternated exposures in which they explored hallways (hall) or viewed their active hand (hand), but in Experiment 2 subjects received two exposures to each condition, while in Experiment 1 only one exposure was given. Hall exposure produced greater visual change, and hand exposure produced greater proprioceptive change; but in both conditions, when order of conditions was controlled, the sum of performance on visual and proprioceptive tests was not statistically different from performance on the common test. In Experiment 2, adaptive components appeared to be inversely related, both within and between exposure conditions, thus providing some evidence of a reciprocal relationship, but a reliable negative correlation between components was not found. Finally, adaptation increased over alternation-repetition of exposure tasks in the second experiment, even though adaptation appeared limited within any given exposure. Results are interpreted in terms of the linear model, and the possible role of attentional factors in processing sensory inconsistencies is discussed.
在两个实验中，在15分钟内将身体倾斜20度的情况下，进行了本体感受适应性测试（头部 - 手部）、视觉适应性测试（眼睛 - 头部）以及两者综合测试（眼睛 - 手部）。在两个实验中，受试者交替进行两种测试，一种是在走廊中探索（走廊测试），另一种是观察自己活动的手（手部测试），但在实验2中，每种测试条件下受试者接受两次测试，而在实验1中每种条件下只进行一次测试。走廊测试产生了更大的视觉变化，手部测试产生了更大的本体感受变化；但在两种测试条件下，当测试条件的顺序得到控制时，视觉和本体感受测试的表现总和与普通测试的表现相比，在统计学上没有差异。在实验2中，适应性成分在测试条件内和条件之间似乎呈负相关，从而提供了某种相互关系的证据，但未发现成分之间存在可靠的负相关。最后，在第二个实验中，尽管在任何给定测试中适应性似乎有限，但随着测试任务的交替重复，适应性有所增加。研究结果根据线性模型进行了解释，并讨论了注意力因素在处理感觉不一致方面可能发挥的作用。
