Spatial knowledge and geometric representation in a child blind from birth

摘要: 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 those from third object. This task requires child detect distances angular relationship familiar paths she derive therefrom angle new path. Our research indicates locomotion young is guided by knowledge Euclidean properties spatial layout principles for making inferences based on properties.
