VIBROTACTILE PERCEPTION - PERSPECTIVE-TAKING BY CHILDREN WHO ARE VISUALLY-IMPAIRED

The study reported in this article compared the performance on perspec tive-taking tasks of congenitally blind children performing tasks thro ugh haptic exploration, congenitally blind children using a vibrotacti le prosthetic device, and children with low vision using limited visua l abilities. The vibrotactile prosthetic device improved the blind chi ldren's performance on the perspective-taking tasks. When the visually impaired children were asked to perform the tasks through haptic expl oration or the use of limited vision, the perspective-taking tasks did not adequately measure their perspective-taking abilities.
