Barn owls raised with one ear plugged make systematic errors in auditory localization when the earplug is removed. Young owls correct their localization errors within a few weeks. However, such animals did not correct their auditory localization errors when deprived of vision. Moreover, when prisms were mounted in front of their eyes, they adjusted their auditory localization to match the visual error induced by the prisms, as long as the visual and auditory errors were within the same quadrant of directions. The results demonstrate that, during development, the visual system provides the spatial reference for fine-tuning auditory localization.
用耳塞堵住一只耳朵饲养的仓鸮，在取下耳塞后听觉定位会出现系统性错误。幼鸮会在几周内纠正它们的定位错误。然而，当这些动物被剥夺视觉时，它们并没有纠正听觉定位错误。此外，当在它们眼前安装棱镜时，只要视觉和听觉误差在同一方向象限内，它们就会调整听觉定位以匹配棱镜引起的视觉误差。结果表明，在发育过程中，视觉系统为微调听觉定位提供空间参考。
