For example, the blindfolded and blind groups were walked along two legs of an isosceles triangle and told to return to the origin. Other than the similarities in navigation without landmarks, the blind and sighted fared similarly when faced with converting descriptions of routes into spatial comprehension by drawing out the route described. This suggests that blind individuals use some form of mental imagery. The use of mental imagery is also demonstrated when blind children are able to recognize objects to which they have had no previous exposure. However, blind and sighted people process information in different ways.
Most sighted people make visual representations of the information they acquire.
Although the blind may use some form of mental imagery, many do not have direct experience with visual representation. Since much of their world is mapped through their haptic senses they benefit when using instruments, such as a cane, to navigate. They are able to infer information about their surroundings without having to recall from memory the length of the cane to determine size characteristics of their environment. An advantage that the blind have over sighted people is that they do not have a problem blending mirror images of objects that are 180 degrees out of orientation. The blind tend to use an absolute orientation for objects.
