为了研究＋Ｇｘ作用对视觉－运动反应的影响，６名健康男性青年在人体离心机上，承受＋３Ｇｘ、＋５Ｇｘ和＋７Ｇｘ作用时，进行视觉－运动反应操作。结果表明，随着超重值的增大，被试者简单视觉－运动反应时延长，漏反应次数增多，反应时概率分布曲线发生了偏移。当被试者进行视觉辨别～运动反操作时，除反应时的变化同简单反应时的变化大同小异外，还观察到了随Ｇ值的增加漏反应和误操作次数增多的现象，感觉敏感性指数逐渐变小，决策标准指数在低Ｇ值时基本不变，在＋７Ｇｘ时增加明显。此外，心率和呼吸频率有随Ｇ值增加而增大的趋势。这表明在＋Ｇｘ作用时人的监控能力受到了一定程度的损害。
To study the effect of + Gx on visual-motor responses, six healthy male youth underwent visual-motor response when subjected to + 3Gx, + 5Gx and + 7Gx effects on a human centrifuge. The results showed that with the increase of overweight, the subjects’ simple visual-motor response prolonged, the number of missed reactions increased, and the probability distribution curve shifted during the reaction. When subjects were visually discerned ~ exercise reverse operation, in addition to changes in the reaction with simple changes in the same, but also observed with the G value increased leakage reaction and the number of misoperation increased phenomenon, sensory sensitivity index gradually Smaller, the decision-making criteria index remained low at low G values, increasing significantly at +7 Gx. In addition, heart rate and respiratory rate tend to increase with increasing G value. This indicates that the human monitoring ability is impaired to a certain degree under the effect of + Gx.
