Description of Research Report: The Vividness of Imagery in a Person Who Has Been Blind for Three Years
When we speak of mental imagery, we immediately tend to think of "a picture in the head" and an image related to vision without taking into account other sensory modalities (Millar, 1990). Paivio (1971) suggested that people who are congenitally blind may be deficient in visual imagery, but that mental images involving other sensory modalities should not differ from those of sighted people. In many cases, the nonvisual mental images of people who are blind appear to be clearer than those of sighted people. Sighted people basically center on vision, giving less weight to the other senses; by contrast, people who are blind need to make the most effective use of the other senses to compensate for their lack of vision.
