Experiments with Modified Grade 2 Braille Codes to Determine Their Effect on Reading Speed

Abstract

Discusses the braille code as a medium of communication and describes four experiments in which Standard English Grade 2 Braille is compared with three “reduced” codes and one “expanded” code. Although the criterion used in the experiments is “speed of reading,” other criteria that need to be taken into account are discussed, the most important being space-saving and ease of learning. The authors see these investigations as part of the preliminary work that must be undertaken if braille is to be made accessible to a larger number of readers, particularly to children and adults of average and below-average ability.
