Although contour rivalry is known to suppress the contribution of the non-dominant eye to some visuomotor mechanisms such as the pupillary light reflex, there have been no reports of the impact of rivalry on accommodation control. In the situation where the accommodation demands in the two eyes are in dynamic conflict, it has been reported that the accommodation response can be modelled in terms of a vector average of the appropriate response in the two eyes. This study compared the binocular interactions in the accommodation system with rivalrous and non-rivalrous stimuli. Accommodation was continuously monitored with an infrared optometer, while the accommodation demand in the two eyes was dynamically modulated independently in the two eyes. When the visual target was perceptually rivalrous the previously described binocular interactions were abolished and the accommodation response closely followed the accommodation demand presented to the dominant eye.
虽然已知轮廓竞争会抑制非主导眼对某些视觉运动机制（如瞳孔光反射）的贡献，但尚无关于竞争对调节控制影响的报道。在双眼调节需求处于动态冲突的情况下，据报道调节反应可以用双眼适当反应的矢量平均值来建模。本研究比较了调节系统中竞争刺激和非竞争刺激下的双眼相互作用。使用红外验光仪持续监测调节，同时双眼的调节需求在两只眼睛中独立动态调节。当视觉目标在感知上具有竞争性时，先前描述的双眼相互作用被消除，调节反应紧密跟随呈现给主导眼的调节需求。
