Abstract
Three approaches to the study of braille reading can be identified. They are (a) the observation of braille reading behavior, for the purpose of drawing inferences concerning the perceptual and cognitive processes upon which braille reading depends, or to discover the behavioral patterns that characterize fast and slow readers; (b) the determination of the legibility of braille characters; and (c) the demonstration of braille reading performance as a function of variables relating to the manner in which braille is displayed. Experiments exemplifying these approaches are described, and some suggestions for future research are made.
