Two groups of children aged 6 to 13, composed of 55 congenitally blind and 64 sighted subjects, were observed in a manual preference test. The activities which strongly differentiate handedness in both groups appeared to be transitive and body oriented, instrumental manipulations and graphical actions. However, bringing the hand to the mouth, pouring and prehension in blind, and pointing in sighted did not differentiate handedness as well. The role of visual deprivation in hand preference orientation is discussed.
对两组6至13岁的儿童进行了一项手动偏好测试观察，其中一组有55名先天性失明儿童，另一组有64名视力正常的儿童。在两组中能强烈区分利手的活动似乎是可传递的、以身体为导向的、工具性操作和图形动作。然而，将手放到嘴边、盲人组的倒水和抓握动作，以及视力正常组的指物动作，在区分利手方面效果不佳。本文讨论了视觉剥夺在利手偏好取向中的作用。
