We investigated perceived range, perceived velocity, and perceived duration of the body rotating in the frontal plane (in roll). Specifically, to examine how shear to the otoliths in the inner ears and tactile pressure to the trunk affect judgments of range and velocity, in two experiments, we manipulated rotating range (30°–160°), rotating velocity (1.8°/sec to 9.6°/sec), mean tilt of the body (−60°, 0°, and 60°), and exposure to the visual vertical. Thirty-three normal or blindfolded participants made verbal judgments of range, velocity, and duration for each combination of these factors. The exponents of the power functions fitted to these judgments were, as a first approximation, .94, .61, and .84 for range, velocity, and duration, respectively, and perceived velocity was proportional to the ratio of perceived range to perceived duration (r = .91). These results suggest that the vestibular and somatosensory inputs are effective on judgments of range, but less so on judgments of velocity, and that perceived velocity may be determined as a ratio of perceived range to perceived duration. In addition, we found that (1) when the range the body has traveled is constant, the perceived range increases as the objective velocity decreases (proprioceptive τ effect); (2) self-motion through the tilted roll sometimes enlarges perceived range and perceived duration but reduces perceived velocity; and (3) the exposure to the visual vertical reduces variability of judgments for range and velocity and also reduces perceived range and perceived velocity of self-motion within a small range through the vertical roll.

人体在额面上旋转的感知范围，感知速度和感知持续时间。

我们调查了人体在额叶平面（滚动）中旋转的感知范围，感知速度和感知持续时间。具体来说，为了检查内耳耳石的剪切力和躯干的触觉压力如何影响距离和速度的判断，在两个实验中，我们操纵了旋转范围（30°–160°），旋转速度（1.8°/ sec至9.6°/ sec），平均身体倾斜度（−60°，0°和60°），并且暴露于视觉垂直方向。33名正常或被蒙住眼睛的参与者对这些因素的每种组合做出了范围，速度和持续时间的口头判断。作为一次近似，适合于这些判断的幂函数的指数分别为范围，速度和持续时间的.94，.61和.84，并且感知速度与感知范围与感知持续时间的比率成比例（r = 0.91）。这些结果表明，前庭和体感输入对范围的判断有效，但对速度的判断则较差，并且可以将感知速度确定为感知距离与感知持续时间的比率。此外，我们发现（1）当人体运动的距离恒定时，随着目标速度的降低，感知距离会增加（本体感受τ效应）；（2）通过倾斜的滚筒进行自我运动有时会扩大感知范围和感知持续时间，但会降低感知速度；（3）暴露于视觉垂直区域降低了范围和速度判断的可变性，并且还降低了通过垂直滚动在很小范围内的感知范围和感知自运动的速度。
