Abstract
  1. Passive linear self-motion estimation along the X and Y axes was investigated in human subjects. 2. A target was viewed from a distance of 0.8 or 2.4 m from the starting point. Subjects were then blindfolded and transported toward the target on a distance of 3.2 m and back to the start. Acceleration was constant: +/- 0.2 or +/- 1 m/s2. The subjects pushed a button on both outward and return paths, when they passed the previously seen target. 3. The results showed anticipation of the target on the outward path, and not on the return. This was identical for both axes and both accelerations. 4. The data are in accord with a model of double integration of the otolith signal, suggesting that linear path integration is a basic sensory mechanism.
摘要
  1. 对人类受试者沿X轴和Y轴的被动线性自我运动估计进行了研究。2. 从距离起点0.8米或2.4米的位置观察一个目标。然后受试者被蒙上眼睛,朝着目标移动3.2米,再返回起点。加速度恒定:±0.2或±1米/秒²。受试者在向外和返回的路径上经过先前看到的目标时按下按钮。3. 结果显示,在向外的路径上对目标有预期,而在返回路径上则没有。两个轴和两种加速度的情况都是如此。4. 数据与耳石信号双重积分模型一致,表明线性路径积分是一种基本的感觉机制。
