我们使用由正交移动随机点图案组成的刺激，研究了视觉诱导自我运动感知（矢量）期间前景和背景刺激之间的相互作用。结果表明，当前景以较慢的速度移动时，诱导具有与前景相同方向分量的自运动感觉。我们将这种新的自我运动感知成分命名为“反向矢量”。使用各种自运动感觉测量和不同刺激条件下，反向矢量的鲁棒性得到了证实。潜在的相关因素，如前景和背景之间的相对运动，以及眼动信息和自我运动感知的误配准之间的相互作用的机制进行了讨论。(C)2000爱思唯尔科技有限公司版权所有。
We investigated interactions between foreground and background stimuli during visually induced perception of self-motion (vection) by using a stimulus composed of orthogonally moving random-dot patterns. The results indicated that, when the foreground moves with a slower speed, a self-motion sensation with a component in the same direction as the foreground is induced. We named this novel component of self-motion perception 'inverted vection'. The robustness of inverted vection was confirmed using various measures of self-motion sensation and under different stimulus conditions. The mechanism underlying inverted vection is discussed with regard to potentially relevant factors, such as relative motion between the foreground and background, and the interaction between the mis-registration of eye-movement information and self-motion perception.
