中文摘要：

目的比较上下倒视条件下定位和定向训练对受试者视觉-运动协调能力提高的影响,为空间运动病的防护和感觉冲突适应训练方法的设计提供参考。方法选取16名受试者在上下倒视条件下进行迷宫测试,并分别进行30min的定位和定向训练后再次接受迷宫测试,分析和比较完成迷宫测试的时间和出错概率。结果两种训练后完成时间和错误率都显著下降,并且不同训练方式的结果也有显著性差异,定向训练的效果明显优于定位训练。结论在由视觉改变引发的感觉冲突环境下,经过相应的任务训练后对于未训练任务的适应性提高也同样有效,从而使得人视觉-运动协调能力提高进而适应感觉冲突的环境,并且不同的训练方式对于适应性的提高也有显著的差异性。

英文摘要：

Objective To compare the effects of location and orientation training on the improvement of visual-motor coordination under up-down reversed vision,provide reference for the preventation of space motion sickness and the design of adaptation training for sensory conflict. Method Sixteen subjects were instructed to complete the maze task wearing the up-down reversing prism spectacle before and after the location training and the orientation training. Both trainings lasted 30 minutes respectively. The error rate and the executing time during the maze test were analyzed and compared. Results Both trainings significantly decreased the error rate and the executing time. In addition,the results of different training methods had significant difference,and the effects of the orientation training was better than that of the location training under up-down reversed vision. Conclusions Under the sensory conflict environment arising from the visual change,the adaptation induced by some task train-ing could also be of benefit to some other task training so as to improve the ability of visual-motor coordination and the adaption to the sensory conflict. However,different trainings could have various degrees of improvement.
