Vibrotactile Perception: Perspective Taking by Children Who Are Visually Impaired

In: Journal of visual impairment & blindness: JVIB, Band 88, Heft 6, S. 550-563

Abstract

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