A series of experiments demonstrated that a congenitally blind 2 1/2-year-old child-as well as sighted but blindfolded children and adults-can determine the appropriate path between two objects after traveling to each of those objects from a third object. This task requires that the child detect the distances and the angular relationship of the familiar paths and that she derive therefrom the angle of the new path. Our research indicates that the locomotion of the young blind child is guided by knowledge of the Euclidean properties of a spatial layout and by principles for making inferences based on those properties.
一系列实验表明，一名先天性失明的2岁半儿童，以及视力正常但被蒙住眼睛的儿童和成年人，在从第三个物体前往这两个物体中的每一个之后，都能确定这两个物体之间的合适路径。这项任务要求儿童检测熟悉路径的距离和角度关系，并从中推导出新路径的角度。我们的研究表明，年幼失明儿童的行动是由对空间布局的欧几里得属性的了解以及基于这些属性进行推理的原则所引导的。
