Exploring the ability of subjects to make accurate discriminations by active touch, two studies involving 20 sighted adults investigated sensitivity of the fingertip in perceiving length, using Braille cells as stimuli. Results indicated differential sensitivity of the fingertip to one parameter of active touch: cell height discrimination. (JW)

A comparison of reading rates of 24 print readers and 23 Braille readers on oral reading, silent reading, and studying, found significant differences as a function of reading group and reading task but no group-by-task interaction. Less than one-third of the Braille readers read slower than print readers. (Contains references.) (Author/CR)
