• Resumen

  • To examine how individuals with visual impairments understand space and the way they develop cognitive maps, we studied the differences in cognitive maps resulting from different methods and tools for spatial coding in large geographical spaces. We examined the ability of 21 blind individuals to create cognitive maps of routes in unfamiliar areas using (a) audiotactile maps, (b) tactile maps, and (c) direct experience of movement along the routes. We also compared participants’ cognitive maps created with the use of audiotactile maps, tactile maps, and independent movement along the routes with regard to their precision (i.e., the correctness or incorrectness of spatial information location) and inclusiveness (i.e., the amount of spatial information included correctly in the cognitive map). The results of the experimental trials demonstrated that becoming familiar with an area is easier for blind individuals when they use a tactile aide, such as an audiotactile map, as compared with walking along the route.
