"Representational Momentum" (RM) is a mislocalization of the endpoint of a moving target in the direction of motion. In vision, RM has been shown to increase with target velocity. In audition, however, the effect of target velocity is unclear. Using a perceptual paradigm with moving broadband noise targets in Virtual Auditory Space resulted in a linear increase in RM from 0.9° to 2.3° for an increase in target velocity from 25°/s to 100°/s. Accounting for the effect of eye position also reduced variance. These results suggest that RM may be the result of similar underlying mechanisms in both modalities.
“表征动量”（RM）是指移动目标的终点在运动方向上的错误定位。在视觉中，RM已被证明会随着目标速度的增加而增加。然而，在听觉中，目标速度的影响尚不清楚。在虚拟听觉空间中使用移动宽带噪声目标的感知范式，当目标速度从25°/秒增加到100°/秒时，RM从0.9°线性增加到2.3°。考虑眼睛位置的影响也降低了方差。这些结果表明，RM可能是两种模态中相似潜在机制的结果。
