The spatial imagery in blind children: Abilities to scan and rotate tactile objects’ shapes

Summary/Abstract: The aim of the research was to explore the ability of spatial imagery in blind students, particularly their abilities to scan and mentally rotate tactile objects’ shapes. The results demonstrate that the older the blind children are, the easier it is for them to differentiate shapes, but only in case when one of two objects is rotated. It may mean that the ability of mental rotation is developing during the school years, and the spatial scanning ability is achieved at an earlier age. It was also stated that identification of objects’ shapes is more accurate in an aligned condition than in a rotated condition. It suggests that the mental rotation process is more complicated than the scanning process for blind children to perform.
