Interocular transfer (IOT) of two motion aftereffects was examined in subjects with normal and deficient stereopsis. Normal subjects showed complete (100%) IOT of motion adaptation on coherent motion thresholds, but only partial IOT of a conventional motion aftereffect, supporting suggestions that the latter aftereffect may be mediated at a lower level in the visual pathway than the extrastriate regions implicated in processing coherent motion. This idea was strengthened by an even greater dissociation between the extent of IOT of the two aftereffects among stereodeficient subjects who exhibited very low IOT of the conventional motion aftereffect, but high (> 87%) IOT of the coherence motion aftereffect.
在具有正常立体视觉和立体视觉缺陷的受试者中，对两种运动后效的眼间转移（IOT）进行了检测。正常受试者在连贯运动阈值上表现出完全（100%）的运动适应眼间转移，但传统运动后效只有部分眼间转移，这支持了以下观点：后一种后效可能在视觉通路中比参与处理连贯运动的纹外区域更低的水平上介导。这一观点在立体视觉缺陷的受试者中得到了进一步加强，他们表现出传统运动后效的眼间转移程度非常低，但连贯运动后效的眼间转移程度很高（>87%），两种后效的眼间转移程度之间的分离更为明显。
