Motion aftereffects (MAEs) are thought to result from the adaptation of both subcortical and cortical systems involved in the processing of visual motion. Recently, it has been reported that the implied motion of static images in combination with linguistic descriptions of motion is sufficient to elicit an MAE, although neither factor alone is thought to directly activate visual motion areas in the brain. Given that the monotonic change of musical pitch is widely recognized in music as a metaphor for vertical motion, we investigated whether prolonged exposure to ascending or descending musical scales can also produce a visual motion aftereffect. After listening to ascending or descending musical scales, participants made decisions about the direction of visual motion in random-dot kinematogram stimuli. Metaphoric motion in the musical stimuli did affect the visual direction judgments, in that repeated exposure to rising or falling musical scales shifted participants' sensitivity to visual motion in the opposite direction. The finding that music can induce an MAE suggests that the subjective interpretation of monotonic pitch change as motion may have a perceptual foundation.
运动后效（MAEs）被认为是由参与视觉运动处理的皮层下和皮层系统的适应所导致的。最近，有报道称静态图像的隐含运动与运动的语言描述相结合足以引发运动后效，尽管单独的这两个因素都不被认为能直接激活大脑中的视觉运动区域。鉴于音乐音高的单调变化在音乐中被广泛视为垂直运动的隐喻，我们研究了长时间接触升调或降调音阶是否也会产生视觉运动后效。在听了升调或降调音阶后，参与者对随机点运动图刺激中的视觉运动方向做出判断。音乐刺激中的隐喻运动确实影响了视觉方向判断，即反复接触升调或降调音阶会使参与者对视觉运动的敏感度向相反方向偏移。音乐能诱发运动后效这一发现表明，将单调音高变化主观解释为运动可能有感知基础。
